->'''Nagisa:''' "Do you like this school?" \\
'''Tomoya:''' "..."\\
'''Nagisa:''' "I really, really love it. But nothing can stay unchanged."\\
'''Tomoya (internal monologue)''' ''A girl I've never seen before. The words weren't directed at me. She must be talking to someone in her heart.''\\

Tomoya Okazaki is an [[OrdinaryHighSchoolStudent ordinary high school senior]] who [[BookDumb doesn't take his studies seriously.]] Always [[{{Delinquents}} late for class, he's seen as a delinquent]] by the rest of his classmates, who are busily preparing for their college entrance examinations. He hates his life and the whole town, and the closest thing he has to a real friend is LoserProtagonist Youhei Sunohara, who just barely manages to rise to the level of ButtMonkey at the best of times. Tomoya is thoroughly miserable.

Then one day, while walking to school, he bumps into Nagisa Furukawa, a [[ShrinkingViolet shy girl]] whose only friends at the school have already graduated. Whenever Tomoya sees her around school, she's alone; her classmates scarcely notice she exists, and no one has any interest in befriending her.

No one, that is, except Tomoya, who without even realizing it finds himself taking her under his wing. As he sets out to help her reestablish the school's drama club, he finds himself connecting (or, as it often turns out, reconnecting) with several other girls from the school. Although he doesn't care much about them at first -- he doesn't much care about ''anything'' at first -- he gradually opens his heart to them as they get to know each other better.

The title, [[WordOfGod according to the author]], comes from the Irish word for "family" (although "Clannad" is actually the name of an Irish band, an abbreviation of "Clann as Dobhar" or "the family from Dore) -- and indeed family, along with the related concept of TrueCompanions, is a major theme of ''CLANNAD''.

The original VisualNovel ''CLANNAD'' was made by KeyVisualArts and released in 2004. The {{manga}} adaptation, illustrated by Juri Misaki, was published by Jive between November 2005 and March 2009; Drama [=CDs=] were released in 2007. In September 2007, Creator/ToeiAnimation released TheMovie, directed by Osamu Dezaki. The television series, by KyotoAnimation, aired between October 2007 and March 2008. The VisualNovel and the {{anime}} television series are each divided into two parts, the high school portion, which takes place during the first few weeks of Tomoya's senior year, and the ''After Story'', which takes place later. Two special OVA episodes were made for this series by KyotoAnimation. The first is the [[{{omake}} bonus episode]] 24 in the first season, [[AlternateUniverse ''Another World: Tomoyo Arc'']], and the second the [[{{omake}} bonus episode]] on the final Clannad DVD, [[AlternateUniverse ''Another World: Kyou Arc'']].

([[{{Nerd}} For those who care about such things]]: over at the Anime News Network, ''CLANNAD ~After Story~'' (i.e. season two of the {{anime}} series) [[http://www.animenewsnetwork.com/encyclopedia/ratings-anime.php is currently ranked #3]] among the almost 6000 {{anime}} series and movies listed there -- [[ViewersAreGeniuses at least if you go by]] [[http://en.wikipedia.org/wiki/Bayes_estimator Bayesian estimator]]. It also previously held the #1 spot in a similar listing at [[http://myanimelist.net/topanime.php MyAnimeList.]] Not that online polls are worth the paper they're (not) written on. Still. Interesting.)

Both seasons and the movie are licensed by Sentai Filmworks, the employees of the once-prosperous Creator/ADVFilms. The first two episodes are available online for free. Viewers in the U.S. can watch the subbed versions of both [[http://www.hulu.com/clannad the first series]] and ''[[http://www.hulu.com/clannad-after-story ~After Story~]]'' in their entirety on Creator/{{Hulu}} for free with commercials. Sekai Project will be localizing the visual novel for an international UsefulNotes/{{Steam}} release.

Not to be confused with the Irish band [[Music/{{Clannad}} Clannad]].

----
!!''CLANNAD'' contains examples of:

* AbsurdlyYouthfulMother: Lots of examples but most apparent is Sanae. Just (majorly spoileriffic link!) [[http://www.youtube.com/watch?v=ckH-mSrme6k compare]] her to [[spoiler:Nagisa]]'s midwife, who was Sanae's classmate in high school.
* AccentUponTheWrongSyllable: The English dub's character names, for those accustomed to the Japanese voices. For example, Nagisa is pronounced "Na-GEE-sa" in the dub.
* AccidentalMisnaming: When Tomoya first meets Nagisa's parents Akio and Sanae, they keep inventing bizarre names for him (e.g., "Cosmic-san"). They're not being mean, they're just rather {{cloudcuckoolander}}ish.
* AdaptationInducedPlotHole: If you're watching all three Seasonverse anime in order. Wait, what!? Now ikiryou are eventually doomed to be RetGone, especially if they're discovered? This wasn't in... oh, wait, it ''was'' in ''VisualNovel/{{Kanon}}'', but only if you played the game.
* AdaptationDistillation: The movie compresses a long visual novel into an hour-and-a-half-long movie.
* AdultFear: This show takes a shot at fathers. [[spoiler:Imagine if your wife died giving birth, and you'd raised your child for years, only to have her die in your arms, her last words were that she loved you and didn't know why it was getting so dark. Tomoya broke down and cried, dying and crying out for someone to help him save his daughter.]]
** Akio and Sanae as well. [[spoiler: Imagine if your daughter died giving birth and you were forced to raise her child for five years due to your son-in-law's HeroicBSoD. Then he gets over it and takes her back only for her to become terribly ill and die from the same illness that killed your daughter, leaving your son-in-law to die of despair, clutching the corpse of your five-year-old granddaughter.]] Yikes.
* AdventurousIrishViolins: The musical score often has this as a nod to the Irish connections of its namesake, as well as to invoke a sense of whimsical romanticism and everyday wonder.
* AfterTheEnd: Tomoya envisions a future with all the trappings of such series, with Fūko as the hero's sealed superweapon ("Starfish Manipulator!").
** In addition, the Illusionary World seems to be some sort of extreme CosyCatastrophe version -- a world that has ended and has no sentient life except for one little girl (and her toy) [[spoiler: who turn out to be Ushio, Tomoya's daughter, and Tomoya himself.]]
* AmbiguousGender: In the VisualNovel: Hiiragi Kappei. So effeminate-looking that Tomoya is unsure of whether he is a guy or a girl even after he states his gender. Even after having the truth dropped on him, Sunohara, in a state of denial, chooses to pursue what Tomoya calls "unrequited love." The [[HoYay implications]] are not lost on us.
* AllGirlsWantBadBoys: Nagisa, Kotomi, Tomoyoa, Kyou and Ryou all fall for Tomoya.
* AllThereInTheManual: Fūko's reappearances in the anime are based on a mode in the VisualNovel where, if you obtain the ''Fūko Master'' and ''Fūko Ninja'' statuses, when replaying Tomoyo's route, Fūko will pop up at random times. The Light Orbs and the ResetButtonEnding are both from the original VN as well.
* AlternateUniverse: The first season's {{omake}} episode 24, in which Tomoyo wins (and the her potential romantic rivals don't even make an appearance onscreen), and the DVD-only episode for ''~After Story~'', in which Kyou wins. All the routes in the game are a bunch of [[AlternateUniverse Alternate Universes]] to each other. This actually becomes a ''plot point''.
** Also, within the {{anime}}'s canon storyline, an AlternateUniverse is the result of the Ichinoses' research, as continued by Kotomi after she graduates. Becomes a focal plot point for the GrandFinale.
** May be the way how the miracle at the end happens. [[spoiler:The miracle did not turn back time and save Nagisa, it simply created an AlternateUniverse where Nagisa survives, meaning that Nagisa, Tomoya, and Ushio are still dead in the universe where they died. Interestingly, the miracle requires you to replay or reload to the point where Nagisa dies, the same way you do when you're going for another route and another continuity.]]
* AnachronicOrder: Not so much in the VisualNovel or the {{anime}} series, but definitely in the 2006 Creator/ToeiAnimation movie. Generally, the action therein skips back and forth between two timelines: Tomoya's senior year in high school, when he's falling in love with Nagisa, and [[spoiler: the weeks, months, and then years after Nagisa's death, when Tomoya is going through (and eventually recovers from) his HeroicBSOD.]] So instead of season one followed by ''~After Story~'' -- as in the KyotoAnimation series -- in the movie we get the former and the latter half of the latter interspliced.
* ArcWords: "Day before yesterday I saw a rabbit, and yesterday a deer, and today, you." Said several times by Kotomi to Tomoya. Also ArcWords (appearing essentially unchanged six times) [[ShoutOut in its source]], Robert F. Young's TimeTravel love story, ''TheDandelionGirl''.
** Many of Nagisa's quotes are good examples, especially "Would you like me to take you... to a place in this city where wishes come true?" as well as her very first lines, quoted at the top.
** Nagisa is pretty much the queen of this trope as far as Clannad is concerned. Ironically, she is probably the one who would be most surprised to find out how much meaning her own quotes have.
* ArtShift: Of a more subtle sort, at least: the "Illusionary World" scenes are animated at a sharply higher quality than the main series, with no duplicate frames and consequently very fluid movement. The scenes make heavy use of CG, too.
* AsideGlance: Kyou and Tomoyo each tend to give the audience an AsideGlance whenever they tease resident ButtMonkey Sunohara into another of his stupid outbursts.
** A more poignant example, from near the end of season one: in front of the whole drama club, Tomoyo tells Nagisa, [[GracefulLoser "I'm so glad he chose you."]] The slighted parties -- Kyou, Ryou, and Kotomi -- each give their own version of the AsideGlance. [[{{Tsundere}} Kyou's]] is almost defiant, with a hint of Tomoyo-directed dagger eyes. Her [[PolarOppositeTwins twin sister]] [[ShrinkingViolet Ryou's]] subtler AsideGlance registers shame rather than anger. Subtlest of all is [[EmotionlessGirl Kotomi's]]: her head doesn't even move as she peers at the audience; evidently she's too lost in thought to fully register that Tomoyo has (inadvertently?) insulted her.
** In ''~After Story~'', {{aside glance}}s are common ways to punctuate a joke, especially (but not always) at Youhei's expense.
* AuthorAppeal: Everything [[KeyVisualArts Key/Visual Arts]] usually likes to put in their games comes in here.
** Not quite everything, considering Key's [[HGame background]]
** Tomoyo's design was apparently based on Jun Maeda's taste in women.
* AwesomeMcCoolName: When he first meets Tomoya, Nagisa's dad decides that his name is too wimpy and proceeds to try to think of a better one. Something big and imposing, like "Galaxy Cosmos"...
* AwesomenessByAnalysis: A SubvertedTrope, when [[TeenGenius Kotomi]] plays baseball: at the plate, she starts a thought stream about angles, velocities, and so forth, while fancy schematics and statistics flash by in the background. But when the pitcher actually pitches, Kotomi chickens out, and the ball winds up bouncing off the bat's handle simply by accident.
* [[TheBabyTrap Baby Trap]]: [[spoiler:Ryou attempts this with Kappei in his route, only for the whole lie to fall flat on its face when he reminds her that they haven't had sex, so it's impossible. She then tries again, threatening to have sex with him while he's unconscious in order to get pregnant.]]
* BadassAdorable: Tomoyo and Kyou. The adorable part is fairly obvious, and the {{Badass}} part is typically demonstrated on ButtMonkey Sunohara. (Sometimes they get a [[JerkAss worthier target]].)
* BaitAndSwitchCredits: The first season opening credits prominently feature an important character who doesn't appear until ''~After Story~''. [[CuttingOffTheBranches Might count]] as a SpoilerOpening for players of the VisualNovel. Might count as a bit of a SpoilerOpening even for those who haven't, in that the scene depicted doesn't take place until more than halfway through the GrandFinale.
* BaseballEpisode
* BathtubBonding: Shown with Fuko and Sanae. Also with Ryou and Kyou in their OVA.
* BeautifulDreamer: A hint of this, in the ''~After Story~'' {{omake}} episode 23, set a year before the first episode of season one. Kyou finds Tomoya sleeping in the school courtyard and is about summon her newfound ClassRepresentative powers to scold him for being late to class. Instead she gets lost in noticing [[{{Bishounen}} how beautiful he looks]]. (Unless you choose to view this episode as a prelude to the AlternateUniverse OVA ''Another World: Kyou Arc'', this scene fuses BeautifulDreamer with ShipTease.) Note that Youhei spoils things by not only waking Tomoya up but claiming that Kyou was about to pull a [[DudeShesLikeInAComa Dudette, He's Like In A Coma]] on him.
** Not surprising since Kyou is the first girl besides [[ForgottenChildhoodFriend Kotomi]] to fall for Tomoya.
* BelligerentSexualTension: Between Kyou and Tomoya, both in Kyou's route in the VisualNovel and in the AlternateUniverse OVA ''Another World: Kyou Arc''.
* BewareTheNiceOnes: In the VisualNovel, Ryou -- at least if Sunohara continues to pursue what Tomoya calls "[[HoYay unrequited love]]" for Kappei.
* BigDamnHeroes: [[spoiler:Sunohara, of all people]], in Episode 4 of the second season.
* BigSleep: [[spoiler:Both Nagisa and Ushio]].
* {{Bishonen}}: Tomoya, Kappei, Yusuke, Akio.
** Arguably Yohei, for similar reasons as Kappei. Admit it, "baby face" Sunohara is hot, he's just the butt monkey.
** Tomoya's dad in his younger days, before hardships took its toll on one's body. Who did you think Tomoya got his drop dead gorgeous looks from?
* {{Bishoujo}}: Design aesthetic used for just about every female character in the cast.
* BlackComedyRape:
** In the VisualNovel, Tomoya uses an expression involving Kotomi (who has a fear of being bullied) having a tail. Kyou launches a thorough investigation and checks breast size while she's at it. Kyou later uses threats of "massages" to coerce Kotomi. This is downplayed -- somewhat -- in the {{anime}}.
** When visiting Ushio and Tomoya, Fuko worriedly asks if Tomoya slipped any sleeping pills into the food he prepared.
* BlueWithShock: Kotomi and Tomoya after receiving a bad fortune. Nagisa and her mother also do this separately in dramatic fashion, with identical lightning strikes in the background.
* BluntMetaphorsTrauma: Ah, Kotomi and your continued abuse of Japanese wordplay. Half the time she doesn't get the joke being made and the other half she's made a [[IncrediblyLamePun horribly obvious one]], often leading into a...
* BokeAndTsukkomiRoutine: As part of his effort to socialize Kotomi, Tomoya tries to teach her this. It culminates in Kotomi, Ryou, and Nagisa working together to learn the ''tsukkomi'' role, with Kyou as their strict teacher.
** Youhei, as befits the resident ButtMonkey, invariably and unwittingly winds up in no end of {{Boke And Tsukkomi Routine}}s. Often with Tomoya, but with many of the other characters, too.
** Tomoya's character revolves heavily around being a tsukkomi and he tries to be one with just about every character, whether it be verbally or just in his thoughts. It doesn't work too well on Kotomi though since she just doesn't get it.
** According to Tomoya, he's surrounded by bokkes, namely Nagisa and Ryou. It is for this reason that he can't help but be the tsukkomi all the time.
* BoobsOfSteel: Tomoyo. Kyou. ([[AvertedTrope Averted]] with Kotomi.)
** Kotomi's assets are due to her being based on the HotLibrarian, a common DatingSim character.
* BookEnds: Clannad After Story begins and ends with a scene of [[spoiler:Tomoya and his father walking through a field of sunflowers.]]
* BreakHerHeartToSaveHer: Not as extreme as some other examples, but in Tomoyo's Other World episode, Tomoya breaks up with Tomoyo in order to prevent himself from stopping her from accomplishing her goal. Tomoya was perfectly aware that she would never forgive herself if she failed. As per typical Clannad, it's really painful to watch him say things like "I didn't love you" in order to make Tomoyo leave.
* BreakingTheFourthWall: At one point in the visual novel, Tomoya says that they should stop kicking Sunohara because the current screen looks wierd.
* BreakoutCharacter: Tomoyo, who got her route extended in ''Tomoyo After''.
* BreakTheCutie: Tomoya is a male example.
** [[spoiler:Poor Kyou and Ryou.]]
* BreatherEpisode: In ''~After Story~'', episodes 19 and 20 have elements of this. Not that they're light and fluffy -- they're {{Tear Jerker}}s in their own right -- but at least in comparison with [[spoiler: episode 16, in which Nagisa dies giving birth to Ushio; episode 17, in which we learn that Tomoya, in his grief over Nagisa, has fallen into [[HeroicBSOD such a severe depression]] that he has essentially ''ignored his own daughter for five years'' and thus become precisely what he hated most about his own father; episode 18, in which Tomoya reconciles with Ushio but bursts into tears (and takes us with him) when telling Ushio about Nagisa -- and of course, episode 21, in which Ushio (and possibly [[DeathByDespair Tomoya]]) dies.]]
** The first half of ''~After Story~'' episode 16 serves as a breather '''half'''-episode. [[spoiler: Because of the episode's [[DownerEnding second]] [[DeathByChildbirth half]], it's easy to forget how cheerful and optimistic the reunion scene is, and what a relief after all the tension of episode 15. This is the last time we see Tomoya, Nagisa, Kyou, Ryou, Kotomi, and Youhei together; leaving aside the WhereAreTheyNow montage in the GrandFinale, this is the last we see of Ryou, Kotomi, or Youhei.]]
** It's odd to consider the first episode of a season as a breather episode, but episode 1 of ''~After Story~'' certainly qualifies. After the power of the end of the first season, and before all of the nuclear powered emotional scenes later in ''~After Story~'', it starts with the cast... playing baseball?
* BrickJoke: The stars given out to everyone by Fuko [[spoiler:are forgotten due to her coma status prevailing and preventing her from waking]] majorly are seen by the ''viewer''. [[TearJerker Emotional impact]] occurs when the viewer realizes that [[spoiler:the characters cannot remember their actions with her]] but can only be remembered by the stars.
* UsefulNotes/BritishEnglish: A curious example with the Creator/SentaiFilmworks English sub. The American company has Tomoya and Yoshino working with "spanners" (wrenches in American English). Yoshino also releases an album titled ''Love and Spanner''.
* BrokenAesop: People who dislike the ResetButtonEnding of ''~After Story~'' generally think it undermines all of Tomoya's CharacterDevelopment and the message that you should accept your losses and make the best of what you have.
* BrokenGlassPenalty: This happens twice whilst playing baseball. It's Akio's fault both times.
** Tomoya had one in the later part of After. Like father-in-law, like son-in-law?
* BromanticFoil: Sunohara.
* BroodingBoyGentleGirl: Tomoya and Nagisa
* BrotherChuck: Kappei, from the VisualNovel, doesn't make an appearance in any of the {{anime}} adaptations.
* BrotherSisterIncest: Tomoya [[ImagineSpot imagines]] this when Mei talks to him about setting up a relationship.
* ButtMonkey: Sunohara, who is routinely brutally beaten, thrown out windows, and skipped across concrete -- usually at the [[strike:hands]] feet of Tomoyo. And it's nearly always his own fault. In addition, his gullibility makes him a frequent victim of [[TricksterArchetype Tomoya's]] pranks.
** Sunohara "enjoys" an unusual niche among [[ButtMonkey buttmonkies]]: just about everything bad that happens to him is his own fault.
*** Except when it involves Tomoya's pranks. Even though you can tell that Tomoya is true friend when push comes to shove, he's also a jerkass of a friend too. Though, I guess abuse is okay when its anyone on Sunohara.
* ByThePowerOfGreyskull: Parodied with Kotomi, whose naive attempt at a MagicalGirl [[http://www.youtube.com/watch?v=jyKwqfOCsUk impression]] involves an Creator/HPLovecraft incantation. Considering her surprise when nothing happens, [[{{Cloudcuckoolander}} one wonders what exactly she was expecting]].
* CallBack: The "Okazaki SAIKOU!" scene in After Story references Fuuko's dream in Ep. 6 where Okazaki says the same line and is wearing (nothing but) those same black tights.
** There's another CallBack, which doubles as an IronicEcho, in the Illusionary World's GrandFinale that references two earlier events. One of them is in After Story episode 20 where [[spoiler: Tomoya sings Dango Daikazoku to put Ushio to sleep]]. The other is from season 1 episode 22 where [[spoiler: Nagisa ends the play by singing the same song]]. It culminates in this conversation:
--> '''The Girl''' -- [[spoiler: (hums Dango Daikazoku)]]
--> '''The Doll''' -- Wait, I ''know'' [[spoiler: that song]]!
--> '''The Girl''' -- You should. It's [[spoiler: the song you always sang to me]].
* CantHoldHisLiquor: Nagisa becomes fully-flushed drunk the ''second'' she downs her cup and turns into a ClingyJealousGirl.
** Inherited from her mother Sanae.
* CareerEndingInjury: Tomoya was a talented basketball player before the start of the series [[spoiler: until an injury from a physical altercation with his father resulted in him being unable to lift his arm above shoulder-level, forcing him to quit the team.]] This on top of the subsequent emotional neglect is shown to be a major contributor to his delinquency and resentment of the town at the beginning of the series.
* CatchPhrase: Nagisa's "Ehehe" in the game. Subtler in the series.
* CatSmile: Sunohara. Unexpectedly, Tomoya does one, too, at one point.
* CharacterDevelopment: Every character in the series experiences this, but more particularly with both Tomoya and Nagisa. Nagisa shown more confidence of herself at the end of Clannad while Tomoya becomes more open to his feelings. Most of Nagisa's character development is from Clannad while Tomoya's at Clannad ~After Story~.
* ChastityCouple: Tomoya's relationship with Nagisa is strictly hugging but no kissing.
** The VN explores this more than the anime as Tomoya deals with his internal struggle over this. It mostly has to do with Nagisa's soft and fragile demeanor as he is MUCH more forward with Tomoyo in her route.
** In the anime, Tomoya and Nagisa start going out, start holding hands, and then get married. As a married couple, every image of them in bed together shows both of them fully clothed and about 3 feet apart. [[SubvertedTrope But then]], we discover that Nagisa is pregnant. (In fact she announces how it happened: "We have sex and sex makes babies!".) So they ''aren't'' actually chaste, but they certainly appear that way onscreen.
* ChekhovsGun: The significance of the [[spoiler:Light Orbs]].
** [[spoiler:In the anime, Fuko after her arc would be ChekhovsGunman; she makes a few random appearances mostly as PluckyComicRelief while her significance with regards to the dream world and role as a key catalyst to the whole story only becomes apparent in the GrandFinale.]]
* ChewToy: Sunohara. The only time his injuries are not PlayedForLaughs is [[spoiler:when he and Tomoya brawl in the rain as a result of Sunohara's neglect of Mei]].
* CherryBlossoms: ''CLANNAD'' being Key's "spring" work, cherry blossoms are blowing in the wind almost all the time. The first scene of the {{anime}} series -- the scene in which BoyMeetsGirl -- is almost clogged with them.
* ChickMagnet: Tomoya.
* ChildhoodMemoryDemolitionTeam: Used repeatedly.
* ClassRepresentative: Both Ryou and Kyou (in separate classes). ShrinkingViolet Ryou, however, was assigned the job via lottery. Her more outgoing sister [[{{Tsundere}} Kyou]] is in at least her second year as ClassRepresentative.
* CleanPrettyChildbirth: [[spoiler:Ushio's birth is remarkably blood and bodily-fluid free, especially since her mother doesn't survive it the first time around. You'd probably be forgiven for thinking Nagisa just fell asleep. In the true ending, Tomoya gives Ushio her first bath, but she doesn't look like she needs one.]]
* ClipShow: The RecapEpisode for ''~After Story~'', ''Under The Green Tree'', summing up both series.
* CloseupOnHead: With Sunohara and Tomoya. First, a shot of Sunohara (including his shoulders) commenting on something happening in the baseball field. Then, a closeup of Tomoya asking what's going on. A third shot reveals that after Sunohara's closeup, Tomoya somehow ended up sitting on Sunohara's shoulders. Sunohara doesn't realize/react to this until after he answers Tomoya.
* {{Cloudcuckoolander}}: Kotomi, when she first gets drafted by Tomoya. (She gets better though. Somewhat.) Also, Fūko. And of course Sunohara, who, unlike the others, actually ''is'' stupid.
** At least some of the time, Nagisa. And her parents. Actually, as Tomoya [[LampshadeHanging observes]], most of the people in the town have at least occasional aspects of {{Cloudcuckoolander}}.
** A quote from Tomoya "These stupid girls... ARE... EVERYWHERE!"
*** He was referring to Nagisa and Fuko in this particular case but the quote can be applied to many of the characters. He even says the entire town is filled with these stupid people shortly after this quote.
* ColorCodedForYourConvenience: The color of the shield of the Hikarizaka school uniform tells you what year the student is... blue for senior, red for junior and green for freshman.
* {{Combos}}: Tomoyo has a rapid fire sequence of kicks that juggles her opponent in the air, and a combo meter actually appears on screen every time she uses it (on Sunohara). At one point, she and Tomoya do a chain combo. In the Visual Novel, she chain combos with almost everyone on the cast.
* ComingOfAgeStory: It's often pointed out by many characters of the cast that Tomoya is "just a kid" and that he will need to, someday, become a man in order to support his family.
* CompletelyMissingThePoint: Fūko's sister suggests that she stop referring to herself [[ThirdPersonPerson in third-person]], to sound more grown-up. Fūko decides to start using ''[[JapanesePronouns atai]]'', [[JapanesePronouns a first-person pronoun only used by immature little girls.]]
* ConspicuousCG: A lot of it, especially in the AlternateUniverse with the girl and her toy robot.
* ContinuityNod: It's quick and easy to miss, but the driver involved in the accident with the bus that causes Kotomi to have a breakdown is the same guy who blamed Yoshino for damaging his car earlier in the series.
* ConvenientlySeated: Tomoya who's beside the window.
* CookingDuel: Sunohara and Fūko, except with carving.
* CoolBigSis: Misae.
* CosyCatastrophe: In the Illusionary World, the toy informs us that their universe is one in which all sentient life has ended -- except for one little girl. (And his, although he doesn't make a big deal about himself.)
* CryCute: Tomoyo, Kyou, and even Tomoya on a few ocassions.
* CurtainsMatchTheWindow: Almost everyone.
* CuteBruiser: Tomoyo, to an extent.
* CuteLittleFangs: Pop up now and then, when a {{Tsundere}}-type gets really angry. Also, Misae-san.
* DarkerAndEdgier: ''~After Story~'', especially in the second half.
* TheDayTheMusicLied: The VN several times starts playing emotional music during scenes that are set up to be misleading either to the audience or characters. Such as Tomoya starting to tell Tomoyo that Sunohara loves her, or when Kyou pulls Tomoya aside to show him a love letter, the assumption being that it's from her to him. The music starts in both cases only to get cut short by Sunohara butting in to say he wants to fight Tomoyo or an irritated Kyou explaining it was from some boy to Ryou.
* DeadpanSnarker: Tomoya.
* DeathByChildbirth: [[spoiler:Nagisa, in the movie, the {{anime}} series, and the bad ending of the VisualNovel.]]
** [[spoiler: [[SubvertedTrope Subverted]] later in the {{anime}} series, when Nagisa survives through the forced time-reset that Tomoya instigates.]]
* DeathByDespair: [[spoiler: Tomoya collapses in the snow shortly after Ushio's death, pleading for Nagisa -- for anyone -- to save her.]]
* DeathGlare: Tomoya gives one to a couple of creeps trying to hit on Nagisa that Mei has attracted to the bakery.
* DeliberatelyMonochrome: In what surely must be a ShoutOut to ''LightNovel/HaruhiSuzumiya'', the {{anime}} for ''CLANNAD'' begins with [[strike: Kyon]] Tomoya [[{{narrator}} narrating]], telling us how much he hates the town he lives in and his life in general. He's clearly depressed, and the world is presented almost exclusively in white, blue, drab green, and grey. Abruptly [[LoveInterest Nagisa]] appears, almost as if by magic. As Tomoya watches her talk to herself, the monochrome of his world begins to break down. The screen flashes with brilliant colors. A few seconds later, with some DramaticWind and some even more dramatic camera movement, Nagisa turns to look at Tomoya. The screen is awash with vibrant colors, and Tomoya's world has officially changed forever.
** In addition, the {{anime}} series occasionally employs briefer DeliberatelyMonochrome sequences in order to imply a sense of unreality -- for example, when Youhei is in a fog after first waking up.
** Late in the series, a heart-breaking use of DeliberatelyMonochrome - episode 16 of ''~After Story~'' concludes with something of an IronicEcho of the series' opening scene. Whereas the original scene gradually bursts from monochrome to full color as Tomoya and Nagisa first notice each other, here the color palette fades from almost surreal intensity (even the tree trunks are purple!) to nearly black and white,[[spoiler: to signify that Nagisa has died.]]
* {{Delinquents}}: Tomoya and Sunohara are known as this. Tomoyo used to be one but is trying to change.
** It's revealed in the ''~After Story~'' Extra episode that the victim of Tomoya's and Sunohara's second major prank in their second year was [[spoiler:Nagisa]], Kyou being the victim of their first prank.
* DemotedToExtra: Let's just say that ''After Story'' is one hell of a [[DemotedToExtra Demotion To Extra]] for any heroines not named "Nagisa." Justified since After Story is the continuation of her route.
** A better example would be Yukine, who was originally intended to be one of the "main heroines" and her route was supposed to be longer but Jun Maeda was unsatisfied with her route. She still ends up with Tomoya but her route is noticeably shorter and lacking in impact compare to the main heroines (Nagisa, Tomoyo, Kyou, Kotomi, Fuko). All of the heroines take a back seat to Nagisa but it was always intended to be that way.
** Fuko after her arc is completed in the first season. She does make occasional reappearances, but the characters don't remember her, and she only shows up for comedic effects for the rest of Season 1. However, it's subverted late in Season 2, when the real Fuko does show up again, mostly for Ushio [[ImTakingHerHomeWithMe kidnap attempts.]]
* DeusExMachina: The ending of the {{anime}} series. There was a lot of foreshadowing for those who know where to look. Also, those who have played the VisualNovel all the way through will recognize it as the true ending. Reactions to this ending often lead into FanDumb territory.
** Considering that [[AlternateUniverse alternate universes]] are also a very important point, a DeusExMachina may not have happened at all. In the universe where [[spoiler:Ushio and Tomoya die]], they really did [[spoiler:die]]. The miracle is that [[spoiler:Nagisa survives in an alternate universe, though it is unclear whether the consciousness of the Tomoya of both universe are the same]]. This is supported in that the miracle does not happen after [[spoiler:their death]], it happens only if you re-play [[spoiler:Nagisa's death scene again]], making it like you're playing another route.
* DiabolusExMachina: Both [[spoiler:Ushio's and Tomoya's deaths, but it turned out all right due to some form of time travel]].
** Also, [[spoiler: Nagisa goes into an early labor on the night where it just so happens to be snowing too hard to get her proper medical care.]]
* DidIJustSayThatOutLoud: In season one, Episode 20:
---> '''Tomoya''': ''* after hitting a home run* '' Did you see that, Nagisa?
---> '''Nagisa''': Yes, I watched you carefully!
---> '''Akio''': [[MeaningfulEcho Love him all over again?]]
---> '''Nagisa''': Ye- Dad!?
---> '''Akio''': ''* cigarette falls out of his mouth* '' Damn it! So she is in love with him!
** Akio again, when he finds Nagisa and Tomoya digging through the shed:
---> '''Akio''': Jeez, why can't you two just go make out in the bedroom like normal teens? ''*{{Beat}}*'' What the hell am I encouraging!?
* DisneyAcidSequence : Tomoya's seriously stuffed-up dream-sequence in Episode 11 of season one.
* DoesThisRemindYouOfAnything: In the AlternateUniverse ''Tomoyo Arc'' {{omake}} episode. Tomoya and Tomoyo are sitting next to each other on a park bench when a distraught Tomoya spills ice cream on his knee. Tomoyo's hand reaches out of frame as she reaches down to wipe the ice cream off his knee. [[spoiler: It's just then that Tomoya announces he's breaking up with her. The visual suggestiveness of the scene only increases the scene's emotional punch.]]
** In the same episode, the moment when the railroad crossing gate first rises has a faint hint of SomethingElseAlsoRises.
** DoesThisRemindYouOfAnything combined with DudeShesLikeInAComa: Sometimes when Fūko falls into one of her {{cloudcuckoolander}} traces, [[TricksterArchetype Tomoya attempts to "help" her back to reality]] by sticking a drinking straw up her nose.
* DoNotCallMePaul: Honorific example: in the BaseballEpisode, Akio calls Misae "Misae-chan" and Tomoyo "Tomo-pyon." They are not amused.
* DopeSlap: Tomoya gives one to Fuko when she uses "Isogai" as her last name, which she [[LineOfSightName read off the neighbor's house]], when staying with the Furukawas.
* DoorStopper: With so many arcs, the Clannad visual novel takes a very long time to complete.
** Especially since you HAVE to complete ALL of the routes to play and complete the ''After Story'' arc, widely considered to be by far the best part of the entire story/game.
* DownToTheLastPlay:
** Basketball match of episode 16 of season 1. Your average stuff of winning by one point included.
** Baseball match in episode 1 of ''After Story'', pretty much the same thing.
* DramaticWind: All those CherryBlossoms won't just move themselves. In TheMovie, DramaticWind is nearly ubiquitous. Maybe that's why Nagisa has to wear a scarf.
** In one episode Kotomi [[InvokedTrope Invokes]] it by opening a window.
* DreadfulMusician: Kotomi's violin playing practically counts as assault though ''she'' thinks her music is lovely.
** She may just be woefully out of practice; her violin playing is a lot less ... oppressive in the {{flashback}}s to her childhood.
* DreamSequence
* [[DudeShesLikeInAComa Dude, He's Like in a Coma]]: Kyou considers this while catching Tomoya taking a nap in the One Year Before episode. Sunohara catches her at it, and calls her out on it. HilarityEnsues
* EarlyBirdCameo: Ushio. In the first season's [[SpoilerOpening opening credits]], no less.
* EarlyInstallmentWeirdness: The video game gags in the first season.
* EarnYourHappyEnding: Quite literally. In the game, you have to go through every character route in order to get the "true" ending of After Story. To put it in perspective this involves around 100 hours of reading, not to mention crying your eyes out on at least half a dozen occasions.
** Also applies in-universe. Tomoya had to go through all those hardships for him to [[spoiler:be reborn as the Garbage Doll in the Illusionary World. He gets his happy ending when Ushio sends him back in time, this time prepared to prevent Nagisa's death]].
* EndOfTheWorldAsWeKnowIt: Parodied in the game with this hilarious quote from Misae:
---> '''Misae''': For Sunohara to have such a cute sister, and for Okazaki to have such a cute girlfriend... If it were the end of the world, it'd be bad for the sister and Furukawa-san, but... I'll say it. It's the end of the world.
* EvenTheGirlsWantHer: Kyou has a group of fangirls in the basketball match.
** In-universe it's "Only the Girls Want Her," much to Kyou's dismay.
* EveryoneCanSeeIt: The viewer can tell Tomoya and Nagisa are the OfficialCouple by the opening credits of the first episode. Most other characters come to this conclusion quickly, too... except that Kyou and Ryou discover this the hard way. But even after a naval battle's worth of ShipSinking, Tomoya and Nagisa just can't see themselves as a couple. [[spoiler: Until the CrowningMomentOfHeartWarming final scene of the final (non-{{omake}}) episode of season one.]]
* EvolvingCredits: When Tomoya's grandmother is introduced in episode 18 of ''After Story'', she shows up in the ending credits as well. At the end of the next episode, Tomoya's father is added to the parade as well. In the final episode, Fūko and Ushio lead the line.
** In the game: the light orbs that the player has collected will appear under the same tree in the game's menu, glow brightly when all 13 are collected, and when you've finally [[HundredPercentCompletion reached the True End]], the Girl in from the Illusionary World will be there.
*** Similarly, in the anime, the scene where they state the episode number and title changed over time, adding orbs of light after major events that roughly correspond to when they are obtained in the game. In the first season, orbs are added at the beginning of episodes [[spoiler: 7, 10, 13, 15, 19 and 22.]] In After Story, orbs are added in episodes [[spoiler: 1, 5, 7, 10, 13, 16 and 21.]] After episode 22 in ''After Story'', the Girl from the Illusionary World is now seen lying in the grass under the tree.
* {{Expy}}: Misae Sagara is similar to Kaname Chidori from LightNovel/FullMetalPanic. They are both voiced by the same voice actress, have similar hair color (blackish blue), similar personality, and Misae's last name is the same as Kaname's love interest. They both also seem to be fond of the suplex. Given that both anime were also made by Kyoto Animation, which may have something to do with both characters having the same voice actress.
* EyesAlwaysShut: Naoyuki Okazaki a.k.a. Tomoya's father is pretty always seen like this. He rarely opens his eyes for more than a second or two.
* {{Facefault}}: Repeatedly. The most amusing one is when Tomoya imagines Fūko announcing over the school intercom that the wooden stars she's been handing out are in fact starfish, with the entire class simultaneously facefaulting in response.
** The one where Tomoya facefaults because Akio mentioned that Sanae's boobs were huge, in front of a ''drunk Nagisa'', no less, is hilarious as well. Though it's more of a {{headdesk}} maneuver.
** Kyou also manages one so hard that she knocked down a door along the way.
* FakedRipVanWinkle: Tomoya pulls this off against a half-asleep Sunohara -- twice, in one minute. Sunohara really is [[WhatAnIdiot that stupid]].
* FamousLastWords:
** "[[{{Understatement}} But I'm a little tired now. May I rest for a while?]]" [[spoiler: Nagisa, dying minutes after giving birth to Ushio.]] While a blizzard clogs the whole city up with [[SnowMeansDeath snow]].
** "[[spoiler: Papa?]] I love you." [[spoiler: Ushio, dying in Tomoya's arms.]] In the [[SnowMeansDeath snow]].
** "Someone! Someone save [[spoiler: Ushio! Nagisa!" Tomoya, before he follows Ushio in death.]] In the very same [[SnowMeansDeath snow]].
* {{Fangirl}}: Mei is something of a Yoshino Yuusuke fangirl.
* {{Fanservice}}: The ShipTease, below, or Kyou in gym clothes in general (such as her {{Gainaxing}} twice in the opening credits bouncing a basketball). A late episode features several of the girls stretching off each other's backs: chest in foreground, everything else blurred out. Goodness, were Ryou's breasts ''always'' that big? Also, the extra episode of the after story has the bath scene of the two sisters.
** Well, she is [[BoobsOfSteel Kyou's]] twin sister.
*** Interestingly, there is ''nothing'' of this sort in the VisualNovel. Not one piece of perverse imagery. The closest thing to Fanservice in the V.N. are a couple of misleading conversations that clarify themselves immediately after for comic effect - most notably, the situation Tomoya and Sunohara engineer wherein [[spoiler:Ryou thinks Nagisa is trying to confess to her. She's actually trying to ask for advice on forming the drama club.]]
*** Another is when Tomoya seems to be about to have [[spoiler: sex with Tomoyo, when he is putting his hand on her breast while she's lying down on a desk. A teacher walks in and Tomoya threatens her to avoid punishment and embarrassment for Tomoyo. Many fans were not pleased with the interruption.]] It is hinted to have actually happened in a bad end of the route, though, a few days later.
**** The scene takes place in her normal path [[spoiler: it's the reason Tomoya got suspended, and afterward Tomoyo goes to see him to cook him breakfast.]]
* FelonyMisdemeanor: Tomoya and Youhei are considered delinquents, though all they do is skip class and show up late when they do bother to attend.
* TheFellowshipHasEnded: In ''~After Story~'', Tomoya, Youhei, Kotomi, Ryou and Kyou graduate, and Nagisa is unable to revive the drama club [[spoiler: when she repeats her senior year ''again'' due to her illness. Youhei, Kotomi and the Fujibayashi sisters do later visit Tomoya and a pregnant Nagisa, but that's the last we see of them, except for Kyou, until the finale. In the RecapEpisode, Tomoya mentions that everyone reunited for New Year's as well.]]
* FirstGirlWins: Depends on whether you count by order of introduction to the audience or to Tomoya.
** In the first case played as straight as humanly possible, with Nagisa standing at the bottom of a hill, facing the sun, with CherryBlossoms blowing through the DramaticWind. WhatDoYouMeanItsNotSymbolic? [[ViewersAreMorons In case all that wasn't clear enough,]] romantic music soars as the two leads first look at each other. A few seconds later, she's following him like a puppy as the scene keeps flashing to brilliant white light. At the 0:37 mark any GenreSavvy viewer not in deep denial ''knows'' she and Tomoya will become the OfficialCouple.
** By contrast, Kotomi is the "First Girl", chronologically speaking, and in the VisualNovel she can surpass Nagisa to become the VictoriousChildhoodFriend.
*** "Surpass" is an iffy term since Nagisa was never a romantic prospect in Kotomi's route, she was just Kotomi's first female friend.
* FirstNameBasis: Tomoya calls all of the other main girls by their given name without honorific, adding "-chan" for [[http://static.tvtropes.org/pmwiki/pub/images/kotomi-chan.jpg Kotomi]] because she won't notice him otherwise, but he and Nagisa call each other by family name. At one point, Fūko, who approves of them as an OfficialCouple, tries to convince them to be more "adult-like" by switching to a first name basis (complete with -chan and -kun honorifics), but after a stuttering attempt both protest that it's too embarrassing (though Tomoya does manage it by leaving off the "-chan").
** Later in the {{anime}}, in an ''[[BonusMaterial omake]]'' episode set during the summer of Tomoya's senior year, Mei ''finally'' succeeds in getting Nagisa to call Tomoya by his first name. Note that the two have already been going steady for several weeks by this time.
** In the VisualNovel, Ryou and Tomoya switch to first name basis, as well, in her and Kyou's route in the game. It's the final scene in the Ryou end.
*** And in the Kyou route it turns into Ryou's desperate attempt to keep Tomoya interested in her by acting like her sister.
** The same goes for Yukine in her route.
** Kyou calls everyone by their first names.
* {{Flashback}}: A lot of them.
* FlashbackNightmare: Tomoya starts to have these as he gets closer to Kotomi, complete with [[FreezeFrameBonus a seemingly random]] [[ArcWords rabbit and deer.]]
* {{Foreshadowing}}: When Sunohara asks Yukine to be his fake girlfriend, a mishap happens which foreshadows Yukine's story arc.
** Additionally, when the topic of the possibilities of multiple worlds and timelines was mentioned in episode 16 of After Story, Tomoya suddenly remembers Nagisa's play, which is a rough description of ''The World that Ended''
** Ushio's love of the robot toy Tomoya gave her. Not only does she love it because Tomoya gave it to her, it also is related to how much she loves robots themselves-- [[spoiler: since her dad was a robot in the Alternate Universe, after all]].
** More so, the last thing Ushio said before [[spoiler: she collapsed into a fever]] was "I tried; but I just couldn't do it by myself." It seems she's talking about [[spoiler: trying to leave the Alternate World and trying to save everyone]], but wasn't able to.
* ForgottenChildhoodFriend: Non-villainous example. Kotomi Ichinose was Tomoya's childhood friend, yet after [[spoiler:Kotomi's parents died in the plane crash]], Tomoya stopped coming over to her house because Kotomi would not come out. The next time they would meet was when Tomoya wandered into the library in his senior year. (This happens the same way in both the VisualNovel and the {{anime}}).
* GadgeteerGenius: Technically, Yoshino, and later Tomoya as well.
* TheGadfly: Tomoya. Poor, poor Sunohara, his most frequent victim. Then again, you have to be ''really'' stupid to put any faith in what Tomoya tells you.
** Even the trusting Nagisa catches on. Seeing her say candidly "Since occasionally you're a liar" in episode 19 is priceless.
* GainaxEnding: Seriously, to understand the GrandFinale requires a lot of analysis of the dialogue between [[spoiler:Ushio and the Garbage Doll before the Illusionary World collapses]]. Also, one has to wonder why [[spoiler:Nagisa has knowledge of Tomoya wishing that he'd never met her]], as well as if [[spoiler:the reality where the Okazaki family got [[TotalPartyKill TPK'd]] really happened]]. (Yes.)
** You would also have to had paid attention to both Misae's and Yukine's arcs to understand the properties of the Light Orbs.
** Playing the VisualNovel and reading [[http://tstorm.bwys.org/2009/03/clannad-after-story-17-22/ this]] helps.
*** It makes sense for the VisualNovel, not so much for the anime[[spoiler:, because in Episode 20 of After Story, Kyou mentions that she, Youhei, Kotomi and the others planned to visit Okazaki sooner or later, showing that the events after Ushio's death take place in the same timeline in which Tomoya gets to meet and befriend everyone.]] So the [[spoiler: Reset Ending triggered by the Lights is, in the Anime, the result of a gigantic Karmic reward made possible by the Lights, earned by Tomoya with his good deeds in the series, and triggered by Ushio's and Okazaki's death]]. It still works. Just, differently.
** For people who confused about ''After Story'' episodes 16-23, and where episode 24 fits into the timeline, there is [[http://tstorm.bwys.org/wp-media/2009/03/clannad-tv-timeline-diagram.png this.]]
* {{Gainaxing}}: Kyou while ''bouncing a basketball'' in the opening credits of season 1. What a way to get a bloke-viewer's attention.
* GayOption: Yes, there really ''is'' a Sunohara ending (really a gag bad end), made available by dumping Tomoyo just prior to locking onto her route. In it Tomoya decides that Sunohara is the only one for him (to Sunohara's considerable alarm).
** To get the "Sunohara" bad end, you have to push away all of the girls, Tomoyo just happens to be the last one in the sequence to be rejected. Perhaps to poke fun at the player, Tomoya says, despite meeting all these girls, he doesn't the slightest interest in any of them so he must be gay.
* GenerationXerox: As much as Tomoya hates his father for neglecting him to dull the pain of his mother's death [[spoiler: he has become exactly the same to his own little girl Ushio to forget that her birth killed Nagisa.]]
* GenericCuteness: To such an extreme it's nearly impossible to tell just by their appearance which girls are meant to be beautiful in-universe. This leads, almost inevitably, to InformedAttractiveness. (See also.)
* GeniusLoci: The entire city, in certain characters' opinion.
* GenreBusting: It's like a slice-of-life romance drama with a side-order of the supernatural.
* TheGlomp: The one performed by [[http://static.tvtropes.org/pmwiki/pub/images/Kyou_-_get_to_know_Kotomi_better.jpg Kyou on the visibly uneasy Kotomi]] is especially famous.
* GlowingEyesOfDoom: Kyou.
* GoIntoTheLight: Parodied on more than one occasion by Nagisa's very theatrical parents.
* GoOutWithASmile: In TheMovie, [[spoiler: Nagisa's adorable last smile, soon before she dies after giving birth to Tomoya's daughter.]] Subtler in the tv series that followed.
* GrandFinale: Doubles as a [[CrowningMomentOfHeartwarming Crowning Episode of Heartwarming]].
* GratuitousEnglish: Sunohara tries to use some, but his English is so bad "revenge" comes out as more like "rezombie". The anime version of Kotomi's arc ends with a misspelled note in English also spoken in a variety of languages, with varying levels of success. The English note was free of errors in the original game.
** ''I am pretty dog. Thank you, my friend from New York!''
** ''Like the fireball!''
*** Sunohara often uses English in horrible wrong ways. Tomoya often calls him out on it.
** In Tomoyo's extra episode, she present a speech broadcast on television in very broken English, that makes little sense if you actually speak the language (Her speech in the dub is completely different, thankfully). Naturally, when watching it, Sunohara asks what language she's speaking.
** There's a lot of GratuitousEnglish in the series. Also in the songs, especially "[[CrowningMusicOfAwesome Ana]]", the lyrics of which are almost entirely awkwardly translated English.
* GratuitousForeignLanguage: Irish Gaelic, misused in the title (as described at the top of this page) and used in other contexts as well, like song titles.
* HairAntennae: The entire Furukawa family. Except Ushio -- but technically she's an Okazaki.
* HairColors: Hair colors run the usual rainbow gambit, but it is Sunohara's blond hair that Fūko [[LampshadeHanging calls out as unnatural]]. In this instance, she's correct (albeit rude): his hair is naturally dark, like his sister Mei's, and he dyes it blond. We see his natural hair color in some of the {{omake}}s and toward the end of ''~After Story~''.
* HappilyMarried: Akio and Sanae. Later, [[spoiler: Tomoya and Nagisa]]. Possibly Yuusuke and Kouko, although we don't see them together that much. And, leaving aside very minor characters and {{flashback}}s, that's [[AllLoveIsUnrequited pretty much it for the requited relationships]] in the {{anime}} series.
** There is a very good reason why we don't get to see Yuusuke and Kouko together much. In the game, ''After Story'' strictly follows Nagisa's route and Nagisa's route only, meaning that there was no Fuuko story and Yuusuke and Kouko never got married. In the anime, Nagisa's route incorporated everyone's else route but since the original source material never had those two married in ''After Story'', anything deeply related to their marriage just kinda got pushed aside.
* HeadbuttThermometer: In the VisualNovel, Tomoyo checks Tomoya's temperature this way after he claims to have a cold, oblivious to how intimate it might look to others.
* HeadDesk: In ''Clannad ~After Story~'', during Nagisa's 20th birthday, is also her first time drinking sake (the legal age for drinking in Japan is 20). She gets extremely drunk off just one bowl/cup and turns into a ClingyJealousGirl. HilarityEnsues and when Sanae and Akio start messing with him too, Tomoya does a fast headdesk.
* HerHeartWillGoOn:
** The GaidenGame eroge sequel to Tomoyo's route ''Tomoyo After: It's a Wonderful Life'' and the manga based on that (''Tomoyo After: Dear Shining Memories'').
** {{Gender Flip}}ped in the movie. [[spoiler: Nagisa is still dead, but Tomoya and Ushio are still alive.]]
* HeroicBSOD: Tomoya [[spoiler: after Nagisa dies]]. On a far smaller scale, Kotomi's FreakOut, when she thinks that Ryou was involved in the bus accident.
** Nagisa suffers one after accidentally learning more about her parents' past. It nearly ruins her play as a result, until her dad snaps her out of it.
* HesitationEqualsDishonesty: Tomoya says he likes snow in ''After Story'' episode 21 with a long hesitation after being asked if he likes snow. He does not like snow. [[SnowMeansDeath Which is completely justifiable in this anime.]]
* HeterosexualLifePartners: Rie Nishina and Sugisaka (two members from the Choir Club) are implied to be this in the epilogue.
* HiddenEyes: Many characters have moments when they have eyes hidden, particularly Tomoya when he's not feeling well.
* HomoeroticSubtext: The "misunderstanding" between Ryou and Nagisa on the rooftop. In one scene Kyou also appears to like Kotomi a lot, leading to the famous [[TheGlomp Glomp]].
** Tomoya also becomes rather uncomfortable with Kappei because of this, though it eventually dies down when he stops thinking of Kappei as being so girly.
* HopeSpot: [[spoiler: Nagisa opens her eyes briefly after giving birth to Ushio, only to die a moment later. Also, Ushio and Tomoya reconciling after being estranged only for her to die from the same illness that affected Nagisa in the bad ending. Fortunately, in the true ending both Nagisa and Ushio [[Film/MontyPythonAndTheHolyGrail got better]].]]
* HospitalHottie: You'll literally say HelloNurse [[spoiler:Ryou]] in After Story.
* HotBlooded: Akio. All he needs is the mecha.
* HotTeacher: Sanae used to be a teacher, but still remained hot. [[spoiler:Kyou]] becomes one in After Story. Kouko also used to be a teacher.
* HowMuchMoreCanHeTake: Tomoya, on behalf of Yukine's absent brother, battles from dawn until after dark.
** Also applies to practically the entire ''After Story'' in regard to Tomoya.
* IdentityAmnesia: After their deaths, [[spoiler:Tomoya and Ushio forget who they are (or were) when they are reborn into the Illusionary World as the Garbage Doll and the Girl]].
* IllGirl: Nagisa was held back due to illness while her friends graduated. Meanwhile, [[spoiler:Fūko has been lying in a coma for years, and is projecting her ghost into the school]].
* ImTakingHerHomeWithMe!: The adorably innocent [[{{Cloudcuckoolander}} Ibuki Fuuko]] says she wants to do this to little Ushio-chan, Tomoya's daughter, to be her little sister.
** In season one, Tomoya and Nagisa say the same thing about Mei.
* ImagineSpot: Tomoya has quite the amusing imagination! Not so much as to call him MrImagination, though.
* ImpactSilhouette: Sunohara makes his shape in a wall that way thanks to the help of Tomoyo right near the beginning of ''After Story''.
* IndecisiveMedium: The VisualNovel-style gags in the Anime adaptation.
* IndirectKiss: At one point, Nagisa acts flustered when Tomoya reachers over and takes a piece of a pastry she is eating to eat himself. Nothing is said, but Nagisa's reaction makes it clear she understands the implication.
** Again, in the visual novel Kyou points out that Tomoya and Ryou have an indirect kiss, when the latter feeds Tomoya with her chopsticks, then using it to eat.
*** You can also say Miyazawa and Ryou picking off a grain of rice from his lips and eating it counts.
** Whether it was before or after (if she had a taste at all), Tomoya licking Kotomi's ice cream in the Visual Novel counts. Of course, it was an innocent gesture on her part.
* InformedAbility: For a supposed "delinquent", Tomoya is very mild. Onscreen, he merely goes to school late and is a smart-mouth.
** Probably a case of [[CultureClash cultural difference]]. Japan is a more disciplined and polite society than any Western one. Therefore, while Tomoya isn't a delinquent by most Western standards, he may be by Japanese standards.
* InformedAttractiveness: Nagisa is supposedly more attractive than average, but this isn't evident in her character design. She's drawn as cute, of course, but so are almost all female characters in the series, to the point where it blurs into GenericCuteness.
* InnocentCohabitation: Tomoya temporarily moves in with Nagisa and her family due to issues with his dad. Sunohara is shocked when he finds out and is rather annoyed when Tomoya continues to insist that [[SheIsNotMyGirlfriend they aren't a couple]].
** [[PlayingWithATrope Played with]] in the VisualNovel. Akio outright admits he wants Tomoya to have sex with Nagisa, and Nagisa herself wants to but isn't forward about it.
* InstantFanClub: Fuko's. If provoked, she can summon her admirers as an attack.
* IntertwinedFingers: Ryou and Nagisa.
* IronicHell: Discussed in parody during Kotomi's tsukkomi training, when Kyou describes the different worlds awaiting a tsukkomi, including the hell of all tsukkomis, the hell of lame jokes that cause people to FaceFault, and the one that really frightens Kyou and Tomoya, the hell with no punchlines...
* ItIsAlwaysSpring: In season one (leaving aside the [=OVAs=]), all of which takes place within a few weeks.
** A SubvertedTrope after Kotomi's arc, when the girls switch to the summer uniforms from ''[[ContinuityNod Tomoyo After]]''.
* IWantMyBelovedToBeHappy: A variant whereby Kyou supports her sister Ryou's attempts to get with Tomoya, despite liking him herself. More thoroughly explored in the Kyou Another World OVA.
* {{Jerkass}} / JerkJock: The soccer club is seriously filled with {{Jerkass}}es / {{Jerk Jock}}s. (To a much lesser extent, so is the rugby team.)
* LargeHam: Yoshino Yuusuke, who after hitting a ball in a baseball match, proceeds to give out a hammy speech about "Intangible Memories"... and gets balled out. (He remembers to call for a time-out the second time he tries it.)
** And Akio. Not surprising since [[spoiler: he was the unofficial king of the drama club when he was in high school, and he even embarked on a career as an actor -- before a near-tragedy with young Nagisa closed off that path.]]
* LeaningOnTheFourthWall: Frequent, usually combined with with SelfDeprecation both toward the character in question and the show itself. Near the beginning of the first season, Tomoya chides Nagisa for being unable to decide if her play is intended to make viewers laugh or cry. Her flustered answers to his questions might almost be a CLANNAD fan flailing in an attempt to explain to a skeptic the appeal of the franchise. In another conversation between Tomoya and Nagisa, this time near the end of the first season, he tells her that her beloved odango song was a bathetic (if not outright pathetic) ending for the emotionally wrenching play she performed. Yes, that's the same song used as the Ending Theme throughout the first season.
* {{Leitmotif}}:
** One for each member of Tomoya's harem -- except poor [[DemotedToExtra Ryou]]. Yes, even Yukine. Also, the first season ED, ''Dango Daikazoku'', functions as both the ED and Nagisa's {{Leitmotif}}.
** The "arc-happy-ending" leitmotif in the first season is rearranged into the second season's opening theme.
* LetHerGrowUpDear: Upon finding out that his daughter Nagisa is pregnant, Akio is torn between denial ("A stork brought it, right?"), happiness at becoming a grandfather, and wanting to strangle Tomoya for sleeping with her. ("Congratulations ... you bastard!!") Nagisa's reaction is classic.
* TheLoad: Nagisa ''thinks'' she's one.
* LoserProtagonist: Sunohara. Tomoya would seem much less impressive without him as a reference point.
* LoveDodecahedron: Tomoya has [[ChickMagnet quite a few admirers]], but is really only interested in Nagisa.
* LoveHurts: Especially in After Story.
* MagicRealism: Though by and large it looks like the series is set in a mundane world just like ours, there are hints of the supernatural lurking just below the surface.
* MagicSkirt: Skirts always cover everything, despite all the kicking that Kyou and Tomoyo do.
** For the audience, that is. Sunohara gets a glance of Kyou's light-blue ''pantsu''. Kyou is not amused.
** Another case: Tomoya. Whenever he and Sunohara meet with Tomoyo and Tomoyo proceeds with the ass-kicking, Tomoya will be in front of Tomoyo while she's giving Sunohara air time. And her kicking leg is raised in a very meaningful angle.
* MaleGaze: Of course. For example, in ''~After Story~'' episode 20, when Kyou greets one of her students with his mother, [[http://static.tvtropes.org/pmwiki/pub/images/s_ass.jpg the camera pans on Kyou's butt, and Tomoya's eyes are seen looking towards Kyou's ass for about two seconds]].
** There is also the interesting camera angles used when Ryou and Kotomi are stretching together in one scene, that constantly features one of the pairs' [[IncrediblyLamePun pair.]]
* MatchmakerCrush: Kyou tries to push Tomoya to be with her sister Ryou at every opportunity ... though she has a crush on him, too. Sometimes she'll make a flirtatious play for Tomoya in the middle of working out a plan to get Ryou and Tomoya together, as if she's forgetting that if Ryou is dating Tomoya, she isn't, and if she's dating Tomoya, Ryou isn't. (This sort of emotional confusion / conflation can be TruthInTelevision even for adults, much less hormonal high school students.)
* MeaningfulEcho: A lot of them. On the joyous end of the emotional spectrum, near the end of season one of the {{anime}}, an otherwise minor echo accidentally gets Nagisa [[DidIJustSayThatOutLoud to confess her love for Tomoya out loud]] for the first time. At the very opposite end of the emotional spectrum, in episode sixteen of ''~Clannad After Story~'', [[spoiler: at the end of Nagisa's ReallyDeadMontage]], there's the {{flashback}} to when Tomoya and Nagisa first met. Again Nagisa says, "Everything changes, eventually. ... Fun things, happy things, they'll all ... They'll all eventually change. But can you still love this place?" -- but this time, at least for the viewer, it means something else entirely.
** One particularly powerful one from ''~After Story~'':
----> '''Ushio:''' "Sanae-san told me...where it was okay to cry...was in the bathroom...[[spoiler:[[CrowningMomentOfHeartwarming and in daddy's arms.]]]]"
* MeaningfulName: The name of the city in which the story takes place is implied to be Hikarizaka (光坂), meaning roughly "light-hill," referring to two important motifs in the story.
* MediumAwareness: In the VisualNovel, Tomoyo, Tomoya, and Sunohara hold a brief conversation with Sunohara's upside-down sprite suspended in front of the screen (he had just been kicked in the air), ending with Tomoya telling him "Hurry up and fall, this screen looks unnatural."
** Also in the VisualNovel, Tomoya can also somehow see how many question marks Kotomi gives him.
* MenCantKeepHouse: Mei visits Sunohara's dorm room to find it's like this. Nagisa notes that it's [[DamnedByFaintPraise 'a very boyish room']].
* MindScrew: See GainaxEnding above.
* MinorInjuryOverreaction: Akio when he accidentally steps on a wood cutting knife. While it probably was painful, he treats it as if it were a mortal wound. Sanae plays along with him.
* MistakenForGay: "''Fujibayashi Kyou is bi!''" Just another of [[TricksterArchetype Tomoya's]] pranks -- although [[http://static.tvtropes.org/pmwiki/pub/images/Kyou_-_get_to_know_Kotomi_better.jpg Kyou certainly isn't helping things.]]
** Tomoya also tricks Nagisa into believing that Sunohara is gay.
** Furthermore, by omitting key details, he makes Ryou think that Nagisa's plea to reinstate the drama club is actually a love confession.
** After misunderstanding something Mei says about playing Cupid, Tomoya has an ImagineSpot in which he and Youhei are lovers.
* {{Montage}}: Usually you'll expect one when Tomoya starts narrating.
** GoodTimesMontage: Sometimes things are going well and we'll get these.
** SadTimesMontage: Sometimes things aren't going well and we'll get these.
* MoodDissonance: The second season Episode 16 ends with [[spoiler:Nagisa dying after giving birth, a {{flashback}} over Tomoya's happy moments with her, and Tomoya wishing he had never gotten involved with her so that she might still be alive. With the words "I should have never met her"]], the screen fades to white, aaaaaaaand ... cue the cheerful, bouncing ending theme ([[spoiler:which showcases the whole cast, ending with Tomoya and Nagisa]])!
* MoodWhiplash: Well, [[spoiler: Nagisa just died and Tomoya fell into the DespairEventHorizon.]] Cue the happy ending theme!
** A minor case in the VN used primarily for comedic effect. During a conversation with Sunohara, you repeatedly state that you are leaving the school and that Sunohara is a stranger to you, accompanied with somber music only for Sunohara to butt in and declare that you keep dissing him out loud.
** There's so much mood whiplash in the series overall you'll need a neck brace by the time it's over.
* MoonRabbit: Mentioned in the first ending song.
* MrFanservice:
** Tomoya. Akio. To a far lesser extent, Youhei Sunohara.
** Yoshino Yuusuke.
* MundaneMadeAwesome:
** Drawing out a baseball bat is usually done in a dramatic way.
** The Dango song gets incredibly epic at the end; very unusual for something that is supposed to be a jingle for rice-balls.
* MyOwnPrivateIDo: [[spoiler: Tomoya and Nagisa elope in ''~After Story~'', but only because they're too poor to afford a "real" wedding.]]
* TheNameIsBondJamesBond: Kyou does this when Tomoya introduces Kotomi to her.
* NeverGotToSayGoodbye: Kotomi. [[spoiler:Her last words to her parents were how she hated them, because they were going to miss her birthday to go to a conference. Their plane crashed]].
* NonstandardGameOver: The so called "Ryou's ending" and the ending to Fuko's route should you had already chosen to be with Nagisa earlier in the game. They are in most ways ''Good Ends'' but are technically ''Bad Ends,'' especially the one in Fuko's route since the events of the normal end still takes place in-universe, you just don't get to see it.
* NotSoWeak: Nagisa. She even defends ''Sunohara'' but refuses to believe she could be even slightly cute or that she isn't a burden.
* [[ObstructiveBureaucrat Obstructive Bureaucracy]]: The student council is ridiculously obstructive to Nagisa's attempts to reestablish the theater club. Until Tomoyo gets elected president, that is.
* OddlyVisibleEyebrows
* OfficialCouple: Nagisa and Tomoya. After all, Nagisa is the "[[FirstGirlWins First Girl]]," Tomoya spends the majority of the show with her, and her theme song (also the season one ending theme) refers to a "mischievous" blue dango and a "kind" pink dango as a couple. The opening scene, where Tomoya describes their long path up to school, could be considered a description of their developing relationship.
* OhCrap:
** Whenever Akio realizes he's just insulted Sanae's bread with [[ImStandingRightHere her standing right behind him]].
** More seriously, the looks on Tomoya's, Akio's, Sanae's and the midwife's faces when they realize [[spoiler: that Nagisa is dying.]]
* OlderThanTheyLook: Sanae and Akio, who look to be in their early to mid twenties yet have a daughter (Nagisa) who is presumably eighteen or nineteen in season one. In addition, Fūko, who looks (and [[BrattyHalfpint acts]]) about ten, is the same age as Tomoya, Kotomi, Ryou, and Kyou.
* OneHeadTaller: Tomoya is almost exactly one head taller than Nagisa. (For that matter, most of Tomoya's potential {{Love Interest}}s are within a few inches of Nagisa in height. But with Nagisa, it's most striking -- and also most relevant, since they're the central arc's OfficialCouple.)
* OneSteveLimit: [[AvertedTrope Averted]] both with Ryou and Kyou (who are twins) and with Tomoya and Tomoyo.
** A more extreme version: in the AlternateUniverse depicted in ''Tomoyo After: It's a Wonderful Life'', Tomoya and Tomoyo move in together with Tomoyo's long-lost younger half-sister -- Tomo. Yes, really.
* TheOnlyOneAllowedToDefeatYou: A SubvertedTrope. [[TheDitz For some reason,]] Sunohara adamantly believes that he and Tomoyo share this dynamic, but he's quickly proven wrong with a kick into the sky and nothing else, not even a passing glance from her. Ouch. Also a CrowningMomentOfFunny.
** He's "quickly proven wrong" to the viewer, but he clings to this notion for about a dozen more episodes and perhaps twice that many thorough and humiliating thrashings.
*** It is explained [[http://www.youtube.com/watch?v=Alu7qWXAmFE here]]
* OnlySixFaces
** Kouko and Yuusuke look like older versions of Nagisa and Tomoya.
** Averted with the Fujibayashi twins. [[spoiler:Even when Kyou cuts her hair as short as Ryou, you can tell the differences.]]
** The character design is the same as the previous Key works. There is even a scene where Kyou makes the exactly same face as [[VisualNovel/{{Kanon}} Ayu Tsukimiya]].
* OurHeroIsDead: [[spoiler:Tomoya and Ushio in the second to the last episode of ''After Story''. Also, Nagisa.]]
* PaperThinDisguise: Akio disguises himself as a rapper at one point. His daughter can't recognize him.
** In the visual novel, he just put on a pair of sunglasses and it somehow ''works''.
* ParentalAbandonment: Tomoya's father neglects him to forget the pain of losing his wife [[spoiler:unfortunately, like father like son.]]
** [[SubvertedTrope Subverted]] by ''~After Story~'' 18, where Tomoya's grandmother explains to him that his father [[spoiler:threw away all his chances to have a good life just so he could raise Tomoya as best as he could.]] To be fair, Naoyuki did have breakdowns in the later years, but when Tomoya realizes that he's been doing a GenerationXerox ever since [[spoiler:Nagisa died]], he wholeheartedly forgives his father, and reconciles with Ushio.
* PlaceWorseThanDeath: How Tomoya feels about the town at the beginning.
* PlayingCyrano: Kyou, to Ryou. In the VisualNovel, this leads to various different results, usually via MatchmakerCrush.
* PoorCommunicationKills: Vital on some of Tomoya's pranks to succeed.
* PoseOfSupplication: Fūko's fan club, after she rejects them.
* PostEpisodeTrailer: The next-episode trailer consists of clips of conversations from the next episode, sometimes spliced from different parts of a scene or even different scenes [[NeverTrustATrailer in order to form new, humorously incongruous dialogue]]. In one instance, [[AllLovingHero sweethearts]] Nagisa and Ryou appear to be happily assuring a terrified [[ShrinkingViolet Kotomi]] that they're bullies.
* ThePowerOfFriendship: One of the major themes of the series.
* PracticeKiss: In the OVA "Another World: Kyou chapter", Kyou offers a practice kiss to Tomoya, who she is secretly in love with, but who at that time is dating her twin sister Ryou. She pulls back at the last second before they actually kiss, but not before they are seen by some of their classmates.
** This also happens in the Visual Novel, choosing to kiss her is important to getting into Kyou's arc.
* PunchedAcrossTheRoom: This tends to happen to Youhei. (A lot.) Sometimes down the hall, out the window, and into the top of a nearby tree. [[CrowningMomentOfFunny And down a garbage chute]]
* PungeonMaster: Nagisa's father Akio.
* PutOnABus: Fuko, with the aid of [[spoiler:massively induced amnesia concerning her very existence]].
** Several characters after ep 14 [[spoiler:Tomoyo, Mai, Yukine, The Choir Club Girls]] and ep 16 [[spoiler:Sunohara, Kotomi, Ryou]] of the second season.
** TheBusCameBack: Kyou turns out to be [[spoiler: Ushio's kindergarten teacher.]]
* RealPlaceBackground: Hikarizaka is based on the Tokyo suburb of Mizuho, as seen in [[http://punynari.wordpress.com/2010/10/03/clannad-anime-pilgrimage/ these pictures]]. There's also a bit of Osaka thrown in for the apartment Tomoya moves into. Tomoya's and Ushio's trip takes place at the tip of Tohoku.
* ReallyDeadMontage: In the anime, you could almost hope [[spoiler:Nagisa, and later Ushio,]] just fell asleep or something, were it not for all the flashbacks.
* RecapEpisode: In one extra episode of the anime, Tomoya talks about what happened in the events of the first season and ''After Story''.
* RedEyesTakeWarning: Kyou has a couple of these.
* RelationshipUpgrade: Many, between Tomoya and Nagisa. That each one is hard-earned -- Tomoya is hesitant to open up; Nagisa is a ShrinkingViolet -- just makes them that much more heartwarming.
* ResetButtonEnding: [[InvertedTrope Inverted]] in this series, as compared to other [[ResetButtonEnding Reset Button Endings]]. This undoes the existing ShootTheShaggyDog ending.
* RidiculouslyCuteCritter:
** Botan, Kyou's pet piglet, who seems to be following in the spiritual footsteps of [[VisualNovel/{{Air}} Potato]] and [[{{Kanon}} Piro]].
** Dango family
* RightBehindMe: A RunningGag has Akio talking about Sanae's bread before learning she was behind him and heard the whole thing.
* RPGElements: After Tomoya successfully pulls off a prank on Fūko, the action will sometimes freeze and a congratulatory "you mastered a new skill!" message will appear to an old video game-style tune. ''Mastered "Shooting Juice up the Nose!"'' Also, when Sunohara wants to join Tomoya and Nagisa to help the theater club, Tomoya's perspective for his response [[ShoutOut changes]] to that of the ''VisualNovel/LittleBusters'' VisualNovel, and [[ButThouMust all of the choices are attacks...]]
* RoomFullOfCrazy: A room covered with certain newspaper articles.
* RunningGag: Any events where someone says Sanae's bread tastes like trash, especially if it's Akio who says it
-->'''Sanae''': ''"My bread... is... trash material!?!?" * runs off crying* ''
-->'''Akio''': ''* stuffs said bread into his mouth and chases after her* "I LOVE IIIITTT!!!"''
** Also, Kotomi introducing herself by saying, without fail, "Hello, Tomoya-kun," no matter who she's (supposed) to be talking to. Tomoya even [[LampshadeHanging lampshades]] the RunningGag.
-->'''Tomoya''': This is getting really old.
** Another from Kotomi: "''[[ShrinkingViolet Ijimekko]]''?" ([[ShrinkingViolet "Is she a bully?"]])
** Periodically after the close of her arc in the anime, Fuko will come back (with a MagicalGirl-esque entrance) to help the protagonists with some dilemma. However, something always comes up to keep her from being able to actually help.
** [[ButtMonkey Sunohara]] getting beaten up periodically (usually by Kyou or [[BadassAdorable Tomoyo]]) is a frequent gag, too.
* SaveOurClub: Nagisa's efforts to rebuild the drama club.
* SayMyName: Numerous names get dramatically shouted over the series. Especially Nagisa's name.
* ScareChord: Invoked [[http://www.youtube.com/watch?v=lpKmNUdXsys&feature=related hilariously here.]]
* SceneryPorn: Everything looks ''incredible''.
* SerialEscalation: Just how much more tear-jerking can the series be?
* SchmuckBait:
** In the extra episode "The Event from One Year Before", Sunohara comes up with the idea to play a prank on the incoming freshmen using a banner ball with a pull cord tag reading "Pull me. It'll be fun!" The freshmen are all too aware of the obvious trap that's in store, but [[spoiler: ''Nagisa'', bless her naïve little heart, pulls the string...and gets a konk on the head from a big metal pan for her trouble.]]
** Tomoya likes to do this in general to Sunohara and Fuko.
** [[DiscussedTrope Discussed]] in episode 20 of ''After Story'' when Tomoya gets a visit. It's about pressing red button if it says "don't press".
* SelfDeprecation: The show frequently pokes fun at itself while LeaningOnTheFourthWall (see above).
** As for the characters, both Nagisa and Tomoya often think of themselves as undeserving to be happy due to their flaws.
* SheIsAllGrownUp: Mei, briefly, in the GrandFinale. Blink and you might miss it. (Trust us, [[PerverseSexualLust you won't want to miss it.]]) The rest of the girls in the series also qualify, though much more subtly. They were already beautiful, but look generally more mature at the end than they do in high school. Justified in that they're all in their mid-20s at this point. Subverted for Fuko, who is still very childlike in appearance and mannerisms though she is the same age as the other characters.
* SheIsNotMyGirlfriend: Tomoya and Nagisa, with gradually increasing frequency, as people see them interacting and come to the natural conclusion. It becomes very evident to every single girl at the end of episode 18.
** [[PlayingWithATrope Played with]] in an episode in which [[TheGadfly Tomoya]] tricks Nagisa into thinking [[PluckyComicRelief Youhei]] is [[BoysLove in love with him]] and being a StalkerWithACrush. In an attempt to protect Tomoya, Nagisa "lies" to Youhei, claiming she and Tomoya are dating. Immediately afterward, she apologizes to Tomoya. (Of course, they kinda ''are'' [[OfficialCouple dating by that point,]] even if they don't admit it to themselves.)
*** In the game they were actually dating, they just hadn't told anybody about it yet.
* ShipSinking: Four alternate romantic options (Kyou, Ryou, Tomoyo, Kotomi) are [[http://www.youtube.com/watch?v=qvemcebvJb8&feature=related swiftly dispatched at once during a tennis match late in the first series]], the girls becoming increasingly miserable as Tomoya's unconscious behavior makes it crystal-clear who the OfficialCouple is. Their tears were matched by tears of ''[[DieForOurShip rage]]'' from shippers, the obviousness of said OfficialCouple be damned. Well, there's always the VisualNovel. And the AlternateUniverse arcs for Tomoyo (season one {{omake}} / episode 24) and Kyou (''~After Story~'' {{omake}} episode 25 / OVA).
** Even in the visual novel, all of the other heroines still fall far behind Nagisa; at least its something though.
** In the main {{anime}}, few of the Tomoya X not-Nagisa shippers really had their hopes up. It was blatantly obvious from the beginning who the [[OfficialCouple official main couple]] was. (See FirstGirlWins and DeliberatelyMonochrome.)
* ShipTease: Perhaps in apology for the impending ShipSinking, an earlier episode features Kyou getting locked in a gym storage room with Tomoya, instantly turning ''[[{{Tsundere}} deredere]]'' to the max and misinterpreting her conversation with Tomoya into thinking she's about to have her first time. Hello, {{Fanservice}}. (The scene also has elements of ArentYouGoingToRavishMe?)
** What makes this ironic is that in the visual novel there are several variation of this scene and, if anything, Nagisa's and Tomoyo's are far more suggestive. The real kicker is that they are all part of ''Yukine's'' route!
*** Even better in that it's entirely possible to get locked in the storage room with [[spoiler:Akio!]]
* ShoutOut: In addition to the standard KyoAni cross-referencing, Kotomi quotes a line from the short story ''TheDandelionGirl'': "Day before yesterday I saw a rabbit, and yesterday a deer, and today, you." (See also ByThePowerOfGreyskull, RPGElements.)
** The summer uniforms from ''[[AlternateContinuity Tomoyo After]]''.
** Episode 20 also has a brief shout-out to the famous music video for ''Thriller''.
*** [[http://www.youtube.com/watch?v=s4huZHu84PI Which has since been dubbed over the scene...]]
** Specific examples of the KyoAni crossreferencing: [[{{Kanon}} Mai's sword and Sayuri's magical staff, along with their ribbons]] make an appearance in the Drama Club's prop box, and in episode 1, the desaturated opening is similar to the first chronological episode of ''SuzumiyaHaruhi''. In episode 17 of ''After Story'' a giant stuffed anteater much like the one from ''Kanon'' is visible in the Furukawa house. Finally, the toy store is called Shiraho, which was the name of the spirit possessing Kano in ''VisualNovel/{{AIR}}''.
** The VisualNovel has {{Shout Out}}s to ''{{Doraemon}}''.
** During Kotomi's path in the Visual Novel, Kyou attempts to get a doll from a game at the arcade that is described surprisingly similar in appearance to [[{{Peanuts}} Snoopy]].
** ''~After Story~'', episode 8 has a shout out to Akiko from {{Kanon}} and her [[LethalChef special home made jam]] (in a deadly combination with Sanae's bread).
** It even has a shout out to the visual novel. Tomoya imagined that life is an RPG. Sunohara wants to join the party. They can use "smoke", "attack" or "magic on him. There is no option to let Sunohara join.
** A shoutout to ''Franchise/AceAttorney'' appears in the visual novel when Tomoya imagines Fuko as his lawyer against the AbsurdlyPowerfulStudentCouncil. Fuko shouts ''"Igi ari!"'' (''"I disagree!"'', the equivalent of the localization's ''"Objection!"'') before making a statement. She does this ''four times''.
** Sanae is wearing [[VisualNovel/{{AIR}} Misuzu's]] apron.
** When Nagisa finds a videotape of her dad's high school acting days, he's playing the lead in ''Theatre/OedipusTheKing'', another family-themed tragedy.
** Kotomi tries to summon [[CthulhuMythos Cthulhu]] with the drama club's magic wand prop.
** The Furukawa Bakery baseball team plays against the [[Music/{{Nirvana}} Smell Like Teen Spirits]].
** [[http://en.wikipedia.org/wiki/De_Vermis_Mysteriis De Vermis Mysteriis]]'' gets a reference in the spell Kotomi utters when they find the magic wand:
--> "Tibi, magnum Innominandum, signa stellarum nigrarum et bufoniformis Sadoquae sigillum."
* SiblingYinYang: Kyou and Ryou.
* SiblingTriangle: Kyou and Ryou, with Tomoya.
* SleepCute: The end of Fūko's arc has Tomoya and Nagisa sitting on the floor of a classroom during the evening, with Fūko in-between, only to have the two end up leaning against each other sound asleep by the next morning.
** And, in Fūko's storyline in the VisualNovel, Tomoya and Fūko wind up like this. Although come morning, it's just Tomoya [[spoiler:until Koumura reminds Tomoya of Fūko's existence, and it turns out she's been invisible and following him around since he woke up.]]
** Yukine, in her story arc, ends up sleeping on Tomoya's lap at Nagisa's suggestion. Sunohara walks in on it, and acts predictably.
* SleepingSingle: Tomoya and Nagisa. In 2009. However, it's due to living in a tiny apartment and poor as all hell, they're not going to spend money on a double futon that probably wont fit in the wardrobe. They probably just brought their old ones from home to save money.
** You must also take their personalities into account. Nagisa's always been shy, and Tomoya is actually quite chaste, having shown very little interest in sex throughout the story, both in the anime and visual novel. He also doesn't want to pressure Nagisa, and it's very obvious that the prospect of sex makes him just as nervous as her, if not moreso. The two just happen to have naturally old-fashioned and ridiculously chaste personalities, and it's clear that they eventually get over it.
* SmokingIsCool: Akio always has a cigarette sticking out of his mouth, even when he plays baseball in heavy downpours.
** And subverted with Tomoya who takes up smoking [[spoiler: after Nagisa's death]]. Where scenes with Akio smoking help play up the fun side of his character, the scenes with Tomoya smoking, complete with close-ups of cigarette butt filled ashtrays, are meant to showcase just how far he has fallen.
* SnowMeansLove: In Tomoyo's route in the VN, Tomoya [[spoiler:breaks up with her [[IWantMyBelovedToBeHappy so that she can focus on her responsibilities]] and become successful]]. After eight months, he walks out of the school one day and sees her standing in the snow in front of him. She tells him that [[spoiler:her responsibilities are concluded]], that she loves him, and that [[spoiler:she has been waiting for him for those whole eight months]]. [[SugarWiki/HeartwarmingMoments They hug.]]
* SnowMeansDeath:
** [[spoiler:Nagisa's]] death might have been preventable, or at least delayed, by modern medicine, except for a massive snowstorm that prevents [[spoiler:her]] from getting access to it until it is too late.
** Several years later, after [[spoiler:Tomoya recovers from his grief over losing Nagisa, he begins acting as a proper father once more to his daughter, Ushio. Then Ushio falls ill, and dies during the winter while out on a trip with Tomoya. Overcome with grief, he collapses in the snow and dies right alongside her.]]
* SocialServicesDoesNotExist: [[spoiler: Naoyuki]] gets off pretty lightly, considering that his physical abuse ended up permanently disabling his son. Both that incident and the subsequent emotional neglect were oddly glossed over in the series, to the point where [[spoiler: Tomoya’s]] tearful gratitude for his 'sacrifices' later on creates some potentially [[InsaneForgiveness mixed]] [[CrowningMomentOfHeartwarming feelings]].
* SomethingElseAlsoRises: See DoesThisRemindYouOfAnything, above.
* SoundtrackDissonance: [[https://www.youtube.com/watch?v=Qe_5GCxaz5M Parting At The Foot Of The Hill]] is a cheerful, cute-sounding tune...that plays over the scene of [[spoiler:Nagisa dying after giving birth to Ushio.]]
* SpamAttack: Tomoyo's signature rapid kicks.
* SpitTake: Tomoya does that when he heard that Nagisa hasn't seen a theatre play before.
* SpoilerOpening: See BaitAndSwitchCredits above.
* StandingBetweenTheEnemies: Yukine stopped two gangs from fighting [[spoiler: by revealing that her brother was DeadAllAlong ]]
* StarfishCharacter: Fūko, and not merely because she loves starfish.
* StayingWithFriends
* StockFootage: Fūko's reappearances.
* StockingFiller: Fūko.
* StoryArc: Fūko (4-9) and Kotomi (10-14) get discrete arcs in the anime based on their paths from the VisualNovel, while the other characters are more mixed together.
** Just about every character arc in the game gets put into the main anime (even the baseball arc) with the exception of Kappei (who doesn't make an appearance) and Tomoyo and Kyou (since their arc revolves heavily around their romantic relationship with Tomoya and would therefore be mutually exclusive with Nagisa's). They get the omake episodes though.
* StrappedToAnOperatingTable: Tomoya finds himself strapped to an operating table (and attended by nurse Kyou) during an odd dream sequence that rapidly grows disturbing.
* StudentCouncilPresident: Tomoyo Sakagami and her spiritual predecessor, Misae Sagara.
* StupidSexyFlanders: Tomoya initially goes through this with Hiiragi Kappei in his arc in the visual novel due to Kappei's androgynous appearance.
* SupportingHarem: Even in the VisualNovel, where other girls have their own routes, it was made obvious that Nagisa is the lead girl.
* SureLetsGoWithThat: Tomoya's modus operandi as a trickster mostly consists of simply not correcting the misunderstandings of others, but going along with their incorrect suspicions, ("Yeah, this is ''exactly'' what it looks like!"), and watching as HilarityEnsues.
* TeamMom: Yukine is the TeamMom for both the city's rival gangs. (This includes acting as the resident "nurse" and provider of sanctuary.)
** Misae is a more official TeamMom to the residents of the boys' dorm over which she presides -- especially the rugby team, but also Youhei and thus by extension Tomoya (although he doesn't actually live there and is not technically under her supervision). She also has a motherly relationship both with Nagisa and with Tomoyo.
* TemptingFate: In the first episode of the first season, Tomoya hopes that Nagisa's father is sane. [[spoiler:It took years after Nagisa's DeathByChildbirth to find out the complete reason on his actions.]]
* TenderTears: Ushio, you just want to give her a big hug when she does.
** Most of the girls are this. Kotomi, Ryou, Nagisa--the list just goes on and on...
* ThemeTuneCameo: The closing theme from the first season, "Dango Daikazoku," pops up frequently in the series, especially in ''~After Story~''. It appears both as a {{leitmotif}} (it's Nagisa's main theme) and as a song in itself, usually sung by Nagisa herself, but sometimes by other characters (usually Tomoya) when they're remembering her.
* ThemeTwinNaming: Kyou and Ryou.
* ThirdPersonPerson: Fuko. Of the small, childish variety. It's ''quite'' [[{{Moe}} endearing]].
** On of the odd things about the Sentai dub/sub is that this character trait is not only missing from the dub, but the sub of the first season as well (granted, a few fansubs of Clannad out there also fail to show that she's speaking in third person). However, it shows up in Sentai's dub and sub for Fuko's appearances in the second season, as it is necessary for her to do so in order for Kouko to call her out on it in the Grand Finale.
** Indeed, the subs for ~''After Story''~ use Fuko's name about twice as often as she actually says it.
* ThoseTwoGuys: Misae's two friends Saki and Yuki. Saki even [[LampshadeHanging comments on their background status]]
--->'''Saki''': Come come now, ours have always been the lives of supporting characters. * Turns to Shima* Go give it your best Main Character!
** Background characters to someone who is a background character to start with.
* ThroughHisStomach: When Tomoyo, The Fujibayashi sisters and Kotomi all individually cook breakfast for Tomoya to cheer him up for getting suspended, things get tense as they show up one by one to deliver three full course meals. [[HilarityEnsues Then Fuko shows up too]].
** Ryou attempts this, [[LethalChef but she's not very good at cooking]]. When Botan steals a bit of the bento she's made, she falls over because it's so bad.
* ThrowTheDogABone: Sunohara actually manages to secure some dignity for himself in Kyou's route and also shows himself to actually be a fairly decent guy. Even though he claims in the same route he would be going for a harem end to solve Tomoya's dilemna. Then again, the fact that just having a little dignity is ''that'' rare for him sort of cancels it out.
** Still in the ultimate canon route ~''After Story''~, the later years writers have not been kind enough to him, he has no clear background, he is not even visible in here, the most you know about him is that he got a job as soon he graduated and that's it.
* ThunderShock: Experienced by both Nagisa and her theatrical mother, Sanae. In Nagisa's case, her antennae-hair is temporarily withered as a result.
* TokenMiniMoe: Mei. Played with to no end (and by Mei herself, no less!) early on in the After Story.
** [[http://svg.kyon.pl/static/img/remiq.net_9435.jpg Onii-chan!]]
*** She has some pretty serious competition from Fuko as well
* TomboyAndGirlyGirl: Nagisa and Tomoyo, although they don't interact much. Nagisa is timid and physically weak, while Tomoyo is confident and physically strong. In addition, Nagisa speaks politely to everyone, even Tomoya, while Tomoyo almost always speaks informally. Interestingly, both Nagisa and Tomoyo seek to invert this relationship; Nagisa wants to become stronger and more confident, while Tomoyo wants to become calmer and more feminine.
* TooDumbToLive: Sunohara. And too comic relief-y to die. [[{{Buttmonkey}} Yeah.]]
* TrainingMontage: Tomoya preparing for Ushio's school sports day.
* TricksterArchetype: Tomoya.
* {{Tsundere}}: Kyou. She wears light blue panties, by the way. This is important.
--->'''Kyou''': ''FORGET IIIIITTTT!!! * [[MegatonPunch kicks the above editor to the sky]]* ''
* TwistedKneeCollapse: Kotomi reads books in this highly uncomfortable position while she sits on a pillow on the floor.
* TwoDecadesBehind: According to TheOtherWiki, the events of the series take place starting in 2003, but there are no cellphones or computers seen ''anywhere'', save for the electric company office. Possibly justified in that the main characters are dirt poor. The series could have easily taken place in TheNineties or even TheEighties. We do see that the Furukawas have upgraded to a flat-screen TV later in ''~After Story~''.
* UnflinchingWalk: Tomoyo's first appearance when she easily dispatches the bullies from a rival school. She doesn't look back when they're flying in the air.
* UnwantedHarem: Nagisa is one half of the OfficialCouple, but if you combine all the routes (like the anime does), Tomoya's other ardent admirers include Kyou, Ryou, Tomoyo, Yukine, Kotomi, Fuko, Misae and (depending on how you look at it) Sanae.
** In Nagisa's route, just Kyou, Ryou, and Tomoyo and Kotomi.
** Could also count in Nagisa's route in the game since Ryou and Kyou already have crushes on Tomoya to begin with, Kotomi liked him when they were kids, and it is recommended that you interact with Tomoyo to the point where she would have fallen him. This is especially apparent with Tomoyo, who expresses disappointment that Tomoya is with Nagisa.
*** Fuko may count but she doesn't show any interest in Tomoya until the very end of her route and only if Tomoya makes the first move (which is rather awkward considering all the romantic tension between Nagisa and Tomoya throughout Fuko's route) or hadn't already chosen Nagisa.
* {{Utsuge}}: KeyVisualArts is known for heart-wrenching plots.
* VerbalTic: Tomoya suggests Sunohara to add 'and a toilet seat cover' in the end of every of his sentences. Sunohara goes through exactly that, hilariously ruining every attempt of him sounding serious.
* WatchingTheSunset: After Nagisa and Tomoya get married, there's a scene of them meeting on a hilltop path, the sun setting behind them. Because of the angle at which we see them, and the way Nagisa's holding her bag, it looks for a moment as if Nagisa's pregnant. Borders on AgainstTheSettingSun, except no words are actually spoken.
* WeddingEnhancedFertility: [[spoiler:Nagisa gets pregnant a few months after marrying Tomoya. She even specifically asks for a baby.]]
* WhamEpisode: Perhaps most notably [[spoiler:Nagisa's death; Ushio's death]]; the GrandFinale; the RecapEpisode (for some). But in a way, each episode starting around when [[spoiler: Nagisa gets sick again and has to drop out of her senior year for the second time]] is a WhamEpisode unto itself, with the whams growing more and more intense and [[TearJerker more and more heart-wrenching]].
* WhamLine:
--> '''Ushio:''' I couldn't pee by myself.
* WhatHappenedToTheMouse:
** It seems that Key doesn't like best friends hanging around when the protagonist is facing huge problems in his life, Sunohara was not seen in the later years of After Story, while the other girls obviously shouldn't have much importance as Tomoya already consumated with his choice, some of them actually get expanded appearances in the anime, whereas Sunohara does not in any way, the only information about him is given when the story is next to it's closure, said information is only about what's his current job and that's it, even his sister got to appear more than him.
*** Cue many fanfics about what he was doing during these times. Sunohara's lack of appearance only made many of his fans with willingness to write crazy to interesting stories for the fellow; only in fanon Sunohara gets to love and be loved by someone.
** Anyone who's not Tomoya or Nagisa, really. We only see brief glimpses of them in the finale, but no real detail as to what they're up to.
* WhereAreTheyNowEpilogue: The montage at the end of the GrandFinale (while "Chiisana Tenohira" plays).
* WhereTheHellIsSpringfield: The location of the town in Japan is not specified.
* WhiteVoidRoom: In the end of episode 16 of ''After Story''.
* WholesomeCrossdresser: In a {{flashback}} episode of ''~After Story~'', Misae's friends get Shima to don a girl's uniform in after he expresses a desire to see what Misae does as the StudentCouncilPresident. Everyone (including Misae) remarks on how cute "she" is, and HilarityEnsues.
* WistfulAmnesia: Both subverted and played straight in the anime [[spoiler:after Fūko disappears]].
* WordSaladLyrics: "Ana"
* WomanInWhite
* TheWonka: Whatever you may say about her odder traits, Kotomi is ''still'' the most successful student in the school. Why carry scissors around everywhere? To cut paper, of course!
* WrongGenreSavvy: Sunohara, who tries raising relationship flags as much as possible and is convinced (Visual Novel) he had a CrashIntoHello with Kappei, refusing to admit that the [[DudeLooksLikeALady dude just looks like a lady]].
** He also applies DudeLooksLikeALady to Tomoyo, thinking that no girl could be so strong - she must be a guy!
* YouGottaHaveBlueHair: Kotomi, Tomoya, and the Fujibayashi sisters.
* {{Youkai}}: [[spoiler:Misae's cat is actually a nekomata that was sent by its deceased former master to pay back a debt of gratitude to Misae, who cheered him up when she met him at the hospital years ago.]]
* ZettaiRyouiki: Various grades:
** Kyou - Grade A.
** Ryou - Grade A when not wearing the summer uniform; she's a Grade C when wearing the summer uniform.
** The rest of the main [[HaremPlot harem]] are Grade C.
** In the {{flashback}} to her high school days, Misae is a Grade A.
*** Shima has Grade A when he's dressed in the girl's uniform in the flashback. N-Not that anyone would keep track!
