->''"The terror, which would not end for another twenty-eight years -- if it ever did end -- began, so far as I know or can tell, with a boat made from a sheet of newspaper floating down a gutter swollen with rain."''

''It'' is a 1986 horror novel by American author Creator/StephenKing. The story is about seven children being terrorized by a malevolent monster -- known only as It -- that shapeshifts to take the form of their deepest fears, but primarily appears in the guise of [[MonsterClown "Pennywise the Dancing Clown"]]. The novel features a nonlinear narrative which alternates between two different time periods (1958 and 1985) and shifts among the different perspectives and stories of its seven protagonists. It deals with themes which would eventually become King staples: the power of memory, childhood trauma and the ugliness lurking behind a small-town façade.

One of the most popular Stephen King novels and widely regarded as a horror classic, ''It'' is also one of the darkest and most frightening, its subject matter being a child-killing supernatural monster with AdultsAreUseless in effect for at least half the story. And yet weirdly enough, there are some really uplifting moments. Along with ''Literature/TheStand'' it is one of the stories that cemented King's reputation as the premier modern horror writer, and like ''The Stand'', it is one of the few examples of an ''epic horror novel'' in literature at over a thousand pages.

In 1990, the novel was loosely adapted into a television movie featuring Creator/TimCurry in the title role. See Film/It1990 for that.

In 2009, Creator/WarnerBros (who owned Creator/{{Lorimar}} when the original TV adaption was made, but was folded into Warner Bros. TV in 1993) announced that a remake of ''It'' was being planned, with Dan Lin, Roy Lee and Doug Davison tabbed to produce. However, the film spent some time in DevelopmentHell until Andrés Muschietti, director of ''Film/{{Mama}}'', was attached and production began in summer 2016, with Creator/BillSkarsgard as Pennywise the Dancing Clown, which released in 2017. See Film/It2017 for that.

Not to be confused with [[Film/{{It 1927}} the 1927 silent film of the same name]], which introduced the phrase "It Girl" to the world. Or 1958's ''Film/ItTheTerrorFromBeyondSpace''. Or the debut album by Music/{{Pulp}}. Or the BigBad of ''Literature/AWrinkleInTime''. Or the Psammead of ''Literature/FiveChildrenAndIt''. Or [[Series/TheAddamsFamily Cousin Itt]]. Or [[Film/ItFollows "It", the deadliest STD ever.]] Or the guys down in the sub-basement who (we hope) run the [[Tropers/TheAdvertisementServer TV Tropes Server]]. [[OverlyLongGag Or the pronoun]].

----
!!''It'' provides examples of the following tropes:

* AbsurdlySpaciousSewer: Crucial events (in both time periods) occur in the sewers under Derry, which feature pipes big enough for adults to walk in without having to bend down, and chambers large enough for multiple adults to have plenty of elbow room. The uncommonly large pipes are [[LampshadeHanging remarked upon by the characters]] and implied to having been influenced by It.
* AbusiveParents: A short list: Beverly's father, Henry's father, Tom Rogan's mother, Eddie Corcoran's stepfather and Eddie Kaspbrak's mother (even if [[MyBelovedSmother she didn't mean it that way]]).
* AdultsAreUseless / InvisibleToAdults: Actually justified, as It has taken complete control over Derry, and that therefore the adults cannot see what is going on.
* AgeAppropriateAngst: Played with. Derry has regular periods where the local EldritchAbomination eats kids. The Losers end the killing spree twice. When they're kids, they recover quickly from all the scares, and they don't get caught up in angsting about all the dead kids. When they're adults...
* AgentScully: Eddie Corcoran doesn't believe in monsters. When the very real monster It attacks him, he assumes it's just an actor in a costume, and he's still searching for the zipper on the 'costume' -- even while he's being eaten alive.
** Stan Uris is this way as well. Even after an actual encounter with IT, he tries very hard to deny the idea that there's anything supernatural going on. As an adult, once he's forced to come face to face with it again, [[spoiler:he takes his own life]].
* AintTooProudToBeg: [[spoiler:It (or rather, ''[[SamusIsAGirl she]]'') pleads for its life when it's on death's doorstep]].
* AlasPoorVillain:
** Both [[spoiler:Victor and Belch]] suffer horrific fates at the hands of IT. [[spoiler:The Losers even express pity for them when seeing their corpses in 1985.]]
** Peter, Moose, Gard, and possibly even Marcia Fadden are all speculated by the Losers to have been killed by It.
** [[spoiler:Henry]] also counts. By the end, he's been driven to insanity and so pathetic that it's not hard to pity him. [[spoiler:Even Mike feels bad for him.]]
* AllTakeAndNoGive: Eddie and his mother (in the past) and Eddie and his wife (in the book's present) both come off as the second variety, with the woman as the domineering Giver, and Eddie as the Taker who is being controlled.
** It's particularly sad because Eddie is ''firmly aware'' of this. He knows that he married a woman just like his mother, and that she's keeping him close with food and pampering. Trouble is, he doesn't know how to fight back.
* AmnesiaDanger: The Losers Club loses its memories after initially defeating IT in the late 50's. When they re-assemble in Derry in the 80's without Stanley Uris, their memories are still quite spotty, and they don't have the knowledge they need to defeat IT until the very last moments. Of course, that might all have been part of the plan.
* AnachronicOrder: The novel jumps back-and-forth between two time periods (the '50s and the '80s), but follows each of these two periods chronologically. (That is, if we don't count normal flashbacks which also appear within each of the two narrative threads.)
* AnArmAndALeg: Pennywise pulls off Georgie Denbrough's arm.
* AngstWhatAngst: Discussed InUniverse. The Losers are much more capable of dealing with all the supernatural horror as children than they are as adults; after defeating It in the sewers, Bill goes home: "After a block or two he begins to walk faster, thinking of supper... and a block or two after that, he begins to whistle."
* AntagonistTitle: "IT" is the EldritchAbomination villain who takes the form of the MonsterClown Pennywise.
* AppearanceIsInTheEyeOfTheBeholder: When the Losers go to It's lair, the sign above the door of the lair is like this: each of them sees it differently.
* ArcWords:
** "He thrusts his fists against the posts and still insists he sees the ghosts." This is a tip of the hat by Stephen King to Curt Siodmak's story "Donovan's Brain."
** "The Turtle can't help you."
** "They float. They all float."
* ArsonMurderAndJaywalking: "I have come to rob all the women... rape all the men... and learn to do the Peppermint Twist!"
* AssholeVictim: [[spoiler:Patrick Hockstetter, Henry, and Tom Rogan.]] Also, Eddie Corcoran's stepfather. No one will miss him much.
* ATruceWhileWeGawk: During the rock fight. All of the kids (RagtagBunchOfMisfits and JerkJock[=s=] alike) stop fighting and turn to watch Victor Criss and Bill Denbrough start a rock-throwing duel, complete with an UnflinchingWalk towards each other. Even ''[[AxCrazy Henry]]'' pauses to watch.
* AuthorAvatar: In this case, Bill (tall, redhead, stutter, horror writer) the author is not Stephen King but Peter Straub.
** One of the men Claude Heroux chopped up in the Silver Dollar was "Eddie King--a bearded man whose spectacles were almost as fat as his gut." (Stephen King's middle name is Edwin.)
* AuthorTract: One occurs against a specific style of writing a few chapters in: we're given details about Bill's struggle in a college writing class, particularly with the man who is the instructor and would-be mentor. Whereas Bill is interested in writing stories for their own sake and cultivating his talent, the instructor insists [[WhatDoYouMeanItsNotDidactic everything must be didactic]] and is more interested in every story being an allegory for a stereotypically left-leaning political or social statement. On a whim, Bill submits one of his works -- one which the teacher had flunked (had, in fact, scribbled "'''PULP CRAP'''" across the front page of) to a horror fiction magazine and gets high praise and a reasonably good cheque; he pins a copy of the acceptance letter to the cork board on the door of the instructor's office. This is the start of a nasty falling out which ends with Bill dropping out of college and going on to become a success anyway.
* AxeCrazy: Claude Heroux.
* BadassBoast: It.
--> I am the eater of worlds, and of children. And you...are...NEXT!
* BathSuicide: This is how the adult Stan Uris kills himself when he learns that It has returned.
* BatmanGambit: [[spoiler:It is vaguely implied that the so-called ''Other'' had a hand in bringing the Losers together and infusing them with the courage necessary to face [[EldritchAbomination the Spider]].]]
* {{Bathos}}: It is a monster from beyond space and time that will feast upon your fear and your flesh...and it wants to know if you have Prince Albert in a can.
* BeatStillMyHeart: [[spoiler:Bill kills IT by tearing out IT's heart and smashing it between his hands]].
* BerserkButton: Ben's temperament might be on the meek side under normal circumstances, but make fun of or hurt Beverly in front of him, and he will get righteously ''pissed.''
* BigBad: [[AntagonistTitle It]], an EldritchAbomination that takes the form of [[MonsterClown Pennywise]].
* BigFriendlyDog: A sad version. Mike's dog, Mr. Chips, is so friendly he [[spoiler:eats the poisoned treats that Henry Bowers feeds him. He even wags his tail as he's dying.]]
* BiggerIsBetterInBed: Zigzagged; during the [[spoiler: [[{{Squick}} sewer sex scene]], Bev finds that Ben is the most well-equipped of the Losers Club. It's very painful for her at first, but he also gives her her first orgasm.]]
* BiggerOnTheInside: The house at 29 Neibolt Street, and the smoke-hole.
* BigGood: [[spoiler:The Turtle. An even higher godlike entity is implied but never explored (except in ''Franchise/TheDarkTower'' novels). That they forget about their friendship after finally killing it seems to ratify the ''Other'' used this bond to its breaking point without having them all go mad.]]
** As far as the Losers go, Bill fills this role. Mike also has shades of it.
* BitchInSheepsClothing: Many of IT's manifestations, including Mrs. Kersh and Pennywise himself.
* BittersweetEnding: [[spoiler:IT is finally defeated and vanquished, but two of the Losers' Club members are dead and the others aren't sure if they stomped out all of the eggs IT laid. Also, most of their hometown is destroyed by a flood with IT's death and the surviving members' memories slowly fade away until they completely forget about each other, but somehow they know that they will be friends forever. King's later works state that as a city, Derry bounces back from the storm and flooding.]]
** [[spoiler: Later books imply that IT survived, though 27 years later [[RealitySubtext no sequel book]] occurred.]]
* BratsWithSlingshots: A slingshot is employed against Pennywise after the Losers make silver slugs to use against the teenage werewolf. Of the seven protagonists, Bev is by far the best shot.
* BrickJoke:
** A rather ghastly one in the book. During one scene, the chief of police shows Mike Hanlon the "tramp chair," a torture device used to discourage transients from stopping in Derry. [[spoiler: It falls through the ceiling and kills the police chief at the end of the book.]]
** The moose blower, introduced in the first part of the book, shows up at the house on Neibolt Street.
** Richie jokes about the futility of fighting IT by sarcastically suggesting bringing a slingshot and sneezing powder. Later in the novel he actually does it. [[spoiler:And it works.]]
* BrokeYourArmPunchingOutCthulhu: [[spoiler:Eddie Kaspbrak loses his arm battling It and dies. He does weaken It enough for the rest of the Losers to kill It.]]
* BrownNote: [[spoiler:The "deadlights", IT's true form, can cause whoever sees them to go insane or die on the spot.]]
* BugCatching: One of the summer pastimes undertaken by the children is catching insects, frogs and other creepy crawlies in the Barrens.
* BullyBrutality: Henry Bowers is shown as perfectly willing to do such things as carve his name into Ben Hanscom's belly (only managing the "H" before Ben gets away), [[spoiler:[[KickTheDog poison Mike Hanlon's pet dog]]]], break Eddie Kaspbrak's arm, nearly drown Bill Denbrough in a dunk tank, and white-wash Stan Uris' face in snow until he draws blood. The other members of his gang are actually [[EvenEvilHasStandards horrified that he would go so far]]. Needless to say, it's easy for [[spoiler:It to use him as TheScapegoat for Its killing spree]].
* BystanderSyndrome: The Losers notice the shockingly high level of this in Derry, caused by IT's toxic influence on the town.
* CallASmeerpARabbit: At the climax, when [[spoiler:the Losers behold Its true form, the best their frail human minds can come up with is "GiantSpider". But the benevolent cosmological entity that helps Stuttering Bill really is a giant turtle.]]
* CallToAdventure: The 1985 storyline begins when Mike Hanlon telephones his six childhood friends and and reminds them of their promise to return to Derry and fight IT again if IT resurfaced.
* TheCameo:
** [[spoiler:Literature/{{Christine}} shows up to give Henry Bowers a lift.]]
** Dick Hallorann of ''Literature/TheShining'' fame also shows up in Will Hanlon's story of how the future cook of the Overlook hotel saved him from the Black Spot fire.
** The 1930s flashback includes an appearance by "Pickman, the guy who paints those funny pictures", from the Creator/HPLovecraft story ''Pickman's Model''.
** King injects himself into the 1905 flashback, describing a character with thick glasses and a gut named "Eddie King." (His middle name is Edwin.)
** [[NotQuiteDead Pennywise]] appears in other Creator/StephenKing novels featuring Derry, and is even mentioned in Franchise/TheDarkTower saga.
** Beverly and Richie as well as several other Derry residents make an appearance in ''Literature/ElevenTwentyTwoSixtyThree''.
** Rebecca Paulson from Haven Village (see ''Literature/TheTommyknockers'' and also her own standalone short story "The Revelations of 'Becka Paulson"), makes an appearance in the climax; it's mentioned she found some of the money which was lost when the roof blew off of the Derry Farmer's Trust.
* CampGay: Adrian Mellon, IT's first victim in 1985, and his boyfriend, Don Hagarty.
* CarvedMark: Henry begins to carve the first letter of his name into Ben's belly with a knife, and would have put his whole name down there if Ben hadn't fought back and gotten away. The scar fades with age, until Ben is reminded of his obligation and it returns as visibly as the day he received it.
* CatchPhrase:
** I worry about you, Bevvie. [[AbusiveParents Sometimes I worry a lot]].
** B-B-B-(*beat*)-Billy Boy.
** I'll kill you all.
** Dontcha wanna balloon?
** We/they all float (down here).
*** When you're down here (with us/me), YOU'LL FLOAT TOO!
* ChekhovsGun: Lots of past events that are mentioned fairly in the story -- like the 1931 execution of the Bradley gang or the fire at the Black Spot -- are returned to and expanded later on.
* ChildEater: IT. So very, ''very'' much.
* ChildHater: Again, Pennywise. Though the one thing he loves about children is their taste.
* ChildrenAreInnocent: Averted with the bullies, Henry Bowers and Patrick Hockstetter being the most psychotic. For example, [[spoiler:Henry chases down Ben, pins him to the ground with help of his fellow bullies, and proceeds to carve his name into Ben's stomach. Patrick Hockstetter is a solipsist, but his world view is shaken when his baby brother is born and he loses some attention from his parents. This makes him afraid that his little brother may exist, so he smothers the baby with a pillow. No one ever finds out. His father does see the evidence and realizes that Patrick is the culprit, but the very concept horrifies him to the point that he goes into immediate and complete denial.]]
* ChildrenAreSpecial: In that they're the only ones able to see It, and resist the mass hypnosis the monster seems to have placed upon the town's adults to make them callous and indifferent to the murderous/evil happenings in Derry.
* CircleOfFriendship: [[spoiler:The main characters do this to help Mike defend himself from a BrainwashedAndCrazy nurse after Henry's attack sends him to the hospital.]]
* ClapYourHandsIfYouBelieve: The Losers use their childlike beliefs as weapons, so that IT can be damaged by things such as silver bullets or an aspirator. Also pretty brutally (if subtly) deconstructed: the ability of beliefs to change the real world works both ways. The kids can use belief to fight back against IT, but the things they believe about their day-to-day lives (which are not so pleasant) become more and more true as time goes on. It's most noticeable with Eddie, whose mother has convinced him he has asthma to the point where he carries a placebo inhaler. Bill's parents are deeply grieving for their murdered younger son, but the more Bill ''wants'' them to come around, the more he ''believes'' they've stopped loving him altogether, and the more distant his parents become. The returning of Ben's scar, too; it didn't come back until he remembered getting it.
** A lack of belief in the supernatural, however, doesn't affect It in the slightest. When It takes the form of the Film/CreatureFromTheBlackLagoon to kill Eddie Corcoran, Eddie is fumbling to find the zipper in the back of the thing's "costume" even as it rips the unfortunate boy's head from his shoulders.
-->''"You're...not...real," Eddie choked, but clouds of grayness were closing in now, and he realized faintly that it was real enough, this Creature. It was, after all, killing him.''
* CoitusEnsues: Two examples.
** [[spoiler:[[{{Squick}} As an eleven year old, Beverly has sex with all of her friends in the sewer]] after defeating It. This is in order to revive their sense of camaraderie and unite the group long enough to escape the sewers of Derry. This is also possibly done as a TakeThat to her father who has already expressed his belief that she is having sex with them. Obviously it was not a scene they could replicate in the movie.]]
** [[spoiler:In the present, Bill and Beverly hop in the sack together when staying at the Derry Inn. Nothing really comes of it; Bill goes back to his wife Audra and Bev is implied to get together with Ben. Bill and Bev's encounter is never mentioned after that.]]
* CollapsingLair: On a rather large scale. [[spoiler:Throughout Derry, the weather goes crazy, the river turns into a flood and much of the city collapses into the ground. This seems to start when the Loser's Club begins to battle with It, and the destruction peaks at It's death... but trails off rapidly. It seems that the act of actually ''defying'' It was enough to unbalance things on a big scale.]]
* ContinuityNod:
** Bev mentions the murders in Castle Rock that took place in ''Literature/TheDeadZone''.
** Dick Hallorann from TheShining appears in a section of the book as a friend of Will Hanlon during the 1920s and 30s when they opened up The Black Spot. When the Maine Legion of White Decency burn the club down, Dick actually saves Will's life.
** They are several references made to [[Film/TheShawshankRedemption Shawshank State Prison]].
** As an adult, Ben lives near [[Literature/NightShift Gatlin]], [[Franchise/ChildrenOfTheCorn Nebraska]] in the town of [[Literature/TheStand Hemingford Home]].
* ContrivedCoincidence: Due to the nature of Derry and It, this happens ''very'' frequently.
--> It was one of those odd quirks of fate or coincidence which sometimes obtain (and which, in truth, obtain more frequently in Derry).
* ControlFreak: [[DomesticAbuse Tom Rogan]], who micromanages every single aspect of his wife's life and beats her when she doesn't do exactly what he wants. It's not made entirely clear whether he carries this attitude to work with him, or if his wife is the sole victim of it.
* CosmicHorrorStory: The monster is perceived as a GiantSpider by the protagonists, because this was the closest analogue that their rational minds could find for Its appearance. Attempting to fight It can result one's mind being flung beyond the edge of the universe, then being driven mad by the Deadlights (which It is merely an appendage of). [[spoiler:After the protagonists succeed in killing It, they [[LaserGuidedAmnesia magically forget]] about the entire incident; apparently this was the only way they could have lived a normal life afterward.]] The novel could also be seen as LovecraftLite: [[spoiler: The Turtle may be an EldritchAbomination and [[GodIsDead may have died]] in the years between the 1958 and 1986 but it is strongly implied that there is ''something'' that still wants them to destroy It once and for all.]]
* CouldntFindAPen: Stan Uris commits suicide in his bathtub because he doesn't want to go back to Derry to face It again. When his wife finds him, she finds that he's written the single word "IT" on the bathroom wall in his own blood.
* CreepyBasement: Georgie Denbrough hates going down to the cellar. He should have been more worried about the drains ...
* DadTheVeteran: Bill's father fought in World War II and brought back a German pistol that Bill uses against It.
* DaylightHorror: This trope is present in spades -- both attacks by It itself and the "mundane", man-made horror of, for example, Beverly's father and other less savory residents of Derry occur just as often during daylight hours as during the night - arguably, some of the most revolting scenes happen in broad daylight (such as the demise of [[spoiler:Patrick Hockstetter at the hands of Leech!It, for instance]]). In fact, all of the protagonists have their first encounter with It (as kids) during the day or early evening. [[spoiler:Both showdowns with It occur during the night, though.]]
* DeadlyDoctor: Mark Lamonica (coincidentally, the younger brother of one of It's 1958 victims, Cheryl), a nurse who is [[spoiler:possessed/influenced by It to try and kill Mike Hanlon when Mike is in hospital from his attack by Henry.]]
* DeadpanSnarker: All the characters have moments of this, but special recognition goes to Richie's ex-girlfriend, Sandy.
--> Richie: When did you change your mind about bringing kids into this shitty world?
--> Sandy: When I finally met a man who wasn't a shit.
* DecoyProtagonist: In the second prologue, when the police are investigating the murder of Adrian Mellon, one of the cops notices that one of the attackers and Mellon's boyfriend both described seeing a clown attack Mellon at the end. The other cops mock him for taking this seriously, but he's sure he's onto something. First-time readers could be forgiven that this cop will play a large role in defeating It. He's never seen again.
* DeepSouth:
** Mike's father Will tells a story from when he was in the Army about a sergeant from Georgia, a grade-A redneck racist asshole, who gave him a hard time just because Will had the audacity to look him in the eye, salute and say "Good afternoon, Sergeant" while on the way back from spending his three-day pass in Boston.
** Averted in Stan's experience. When he gets married, he and his wife Patricia moved to rural Georgia and later Atlanta. Patricia is a bit worried that two Jewish Yankees may face some discrimination (both she and Stan had been victims of it in the past) but nothing like that ever happens to them.
* {{Delinquents}}: Henry Bowers and his friends.
* DepartmentOfRedundancyDepartment: "A nagging unpleasantness began to nag at him."
* DepravedBisexual: Patrick Hocksetter, who fondles the girls in his class but is also interested in propositioning Henry for sex.
* DeusSexMachina: [[spoiler:[[{{Squick}} Bev has sex in the sewer with the other members of the Losers Club]]. Apparently it's supposed to be a metaphor for moving from childhood to adulthood.]] Another level of irony (and possibly a FamilyUnfriendlyAesop) also exists here, when you contrast this with another scene in the book. Bev's father is portrayed as an abusive, overprotective, borderline psychopath. When he learns that she's been playing with boys, he insists — violently — on ''physically'' checking to see if she's still a virgin. [[spoiler:Fortunately, she escapes him.]] At this point, she still is, and the scene plays out like an attempted rape. The real irony of the matter is that Beverly is inspired to [[spoiler:have sex with the boys]] ''because'' of what her father did. He put the idea in her head.
* DidYouJustPunchOutCthulhu: Seven pre-teens managed to defeat a devourer demon from the dawn of time.
* DisappearedDad:
** Ben Hanscom and Eddie Kapsbrak's fathers both no longer figure in their lives -- Eddie's dad is definitely dead, making his mother extremely overprotective of him, while it's never specified whether Ben's dad died or just up and left when Ben was little. In the tv series he and his mother live with his aunt and cousins who bully him and say he's lucky they're willing to take him in, and It takes the form of his father and points to a mausoleum saying 'that's my home now', confirming that he's dead.
** Bev's dad is present in 1958, but apparently in 1985 she hasn't spoken to him in so long she's not even sure if he's still alive. She goes to visit their old apartment to see if he still lives there and finds Mrs. Kersh instead.
* DisposableWoman: It goes after Audra just to cause Bill further pain. [[spoiler:Luckily, Bill is able to save her from being StuffedInTheFridge and cure her Deadlights-induced catatonia]].
* TheDogBitesBack: Half of why It went down the first time. In all It's years of killing and eating children, none of them ever really tried to fight back.
** Embodied in the event referred to as "the Apocalyptic Rockfight". It began when Henry and his gang (Victor Criss, Belch Huggins, DumbMuscle farmboy Moose Sadler, and rich {{Jerkass}} Peter Gordon) chase Mike to the gravel pit at the end of the dump, and the Losers happen to be nearby. They decide to help Mike, and the sheer act of them putting up a fight sends Henry's gang (with the exception of Vic) into blind fury, and shortly thereafter, surprised panic. They manage to fight off all of the bullies and declare that henceforth, the Barrens is officially Losers' Club territory.
* DoggedNiceGuy: Ben Hanscom to Beverly Marsh.
* DomesticAbuser: Tom Rogan. He even has a belt dedicated to using on his wife.
* {{Doorstopper}}: In Holland, a woman pressed charges against a mail company because a copy of ''IT'' '''killed her chihuahua''' when it dropped through the mail chute. The hardcover copy of ''IT'' is 1,135 pages long.
** Hilariously lampooned in Charles [=McGrath's=] "ID," originally published in ''Magazine/TheNewYorker'' and reprinted in George Beahm's ''The Stephen King Companion''. Six-year-old Chuckie Douglas watches as men with chainsaws cut down every tree in Weesquapeckett, Maine, and proceed to clear-cut the entire state ("Paper, Sonny," says one lumberjack who bears a suspicious resemblance to a certain author. "Got to have more paper!"). Not long after, he notices that his dad's right arm is now three feet longer than his left, from carrying a book in his briefcase. Meanwhile, around the world, a luxury liner carrying members of the Book-of-the-Month Club lists to port, a book-delivery truck falls through a solid-iron trestle bridge, and the "Authors Ka-Ki" section of a library floor collapses into the basement and crushes a janitor.
* DownInTheDumps: The Barrens, the place where all the kids go to do anything.
* DrawingStraws: To decide who would take part in the smoke-induced vision.
* TheDreaded:
** IT, of course.
** {{Iron|y}}ically, The Losers [[{{Inverted}} become this to It]].
* DreamSequence
* DrivenToSuicide: After Mike calls Stan with the news that IT has returned, Stan kills himself by slashing his wrists while taking a bath and writes "IT" on the wall in his blood.
** Implied to have been the fate of Branson Buddinger, author of ''A History of Old Derry''.
* EldritchAbomination: [[spoiler:IT's terrestrial form is a being that can change shape, alter reality, and whose very presence causes the population of Derry to become more callous, hateful, and violent. IT's true form is a destructive orange light that exists outside of our universe.]]
* EmpathicEnvironment: The storm that takes place in Derry when [[spoiler:the Losers kill It in 1985.]]
* TheEndOrIsIt: [[spoiler:From the first line, it's uncertain as to whether "the terror" ever really did end. In the final chapters, the possibility is noted that Ben may have missed one of IT's eggs when he was executing her offspring.]]
* EnergyBeings: It, itself. When Bill [[spoiler:initiates the Ritual of Chüd, "It" flings him through It's mind into a "Darkness beyond the universe", towards where It's true form resides as a swirling mass of Orange Light.]]
* EvenEvilHasStandards: Henry Bowers's gang, despite being brutal bullies themselves, are actually appalled by some of the things Henry does to the Losers, such as trying to carve his name into Ben Hanscom's belly or trying to blow up Mike Hanlon with cherry bombs and M-80s. In comparison, this could only apply to Victor. Henry's a terrifying man, and Patrick is really moreso creepy than offensive. It's highly implied in the film that they follow Henry around out of fear than respect or even friendship. Better to side with the psycho than it is to be against him.
* EveryoneIsJesusInPurgatory: An in-universe example: when Bill Denbrough follows a writing course in college, he gets an instructor who keeps insisting that each story has deeper meanings and messages, be it political, religious etc. One day Bill has enough and finally stands up to his instructor, asking him point blank if it has ever occurred to him that sometimes a story can be just a story, without socio-anything. His instructor disagrees.
* EvilIsHammy: Pennywise has his/Its moments in the novel.
* FartsOnFire: [[PlayedForDrama Not played for laughs]]: A fart-lighting scene leads to a homosexual encounter between Henry and Patrick Hockstetter. It's one of the most suspenseful scenes in the book, because the whole thing is witnessed by a hidden Bev who is struggling desperately not to be noticed by them.
* {{Fauxshadow}}: There are a few hints that [[spoiler: Benjamin Hanscom]] will be killed by It; he's straight up told he will die tonight by It, and he's the second to leave the fire after [[spoiler: Stanley Uris]], the character who dies first. By the end of the novel, he's still alive.
* TheFellowshipHasEnded: [[spoiler:After defeating IT for the first time, all the seven members of the Loser's Club never meet again. Eventually, they all go in their separate ways, and completely forget about each other (except for Mike but he implies that even with desperate efforts to remember, he will forget why he's even carrying out the measures. Specifically he brings up the example that he will write his friends down but the ink itself may fade, and even if he can keeps renewing the ink, he may forget why he's doing it and why these names are even relevant).]] Downplayed in the film as [[spoiler:the forgetting isn't really mentioned and it's confirmed that Ben and Beverly end up together, which was only implied in the book]].
* [[spoiler:FemaleMonsterSurprise:]] [[spoiler:It is apparently female and has given birth to eggs.]]
* FictionalDocument: Bill Denbrough's novels, some of which have similar titles to Creator/StephenKing's ones.
* FightingAShadow: [[spoiler:The terrestrial form of IT as the spider is just the physical avatar of the Deadlights outside the universe. Even after the Losers kill the Spider, hints in later novels suggest that IT isn't entirely gone from Derry, even if [=ITs=] ability to physically manifest is.]]
* FinalBattle: Foreshadowed right from the first page.
* FlashbackWithinAFlashback: happens as a side-effect of the book's time-jumping structure. For instance, the adult Ben thinks back on being chased into the woods by Henry as a kid, and within that flashback is another flashback in which he thinks back on the first time he encountered Pennywise months earlier.
* FlatEarthAtheist: Stan.
* FoodEatsYou: Certainly how [=IT's=] fights with the Looser Club must seem to IT, though in this case the "food" was always sentient.
* TheFourthWallWillNotProtectYou: IT, at one point, [[spoiler:[[DoNotAdjustYourSet hijacks the narration]] and boasts about Its age and killing prowess]].
* ForegoneConclusion: No matter how scary or even deadly things get in 1958, we know the Losers Club is going to survive, since they're still alive to come together and decide what to do in 1985.
* {{Foreshadowing}}: IT scares Beverly in the bathroom and her dad rushes in, demanding what all the screaming was about. Beverly lies and says that she just saw a spider in the drain. [[spoiler:Which is IT's true physical manifestation. They even fight it in the sewer.]] Also, in the last section of the book, when [[spoiler:Al chases Beverly into the Barrens, trying to kill her because he's been possessed by IT]] Lars Theraminius starts crying because he sees Marsh turning into a spider. It gives him nightmares for a week.
** The dragon/magic stones story Bill tells the others in the TV series is very similar to [[spoiler:how the FinalBattle plays out]].
* FormerlyFat: Ben Hanscom was fat as a kid, but ended up slimming down as a teenager.
* FreeRangeChildren:
** The parents of the main kids might as well be nonexistent, considering how they let their kids roam around unsupervised all day ''despite there being a killer preying on children loose in town,'' even given the more relaxed attitude of the time period. Of course, one of Pennywise/It's powers seems to be making the townsfolk indifferent to—perhaps even accepting of—his evils, so it might be justified.
*** Partially justified in story for Bill Denbrough's parents, whose grief over the death of his younger brother has made them both withdraw emotionally (even by the standards of the era).
*** Ben's mother at least gives him a watch to make certain he knows to be home by a certain time, ready to call the police if he's at all late.
* GangOfBullies: Henry Bowers and co.
* {{Gasshole}}: One of the bullies communicates solely via burping into victim's faces; he is aptly named Belch.
* GayBarReveal: The landlord of a failing bar in Derry, the Falcon, is relieved when business picks up, in the form of quiet, youngish men who start patronizing his establishment. It takes him months to work out that his bar has become the unofficial gay bar of the town. He isn't bothered too much by the revelation however, as the new clientele seem to hardly ever find reasons to start fights and mess up the bar.
* GeniusLoci: It is often equated with Derry, the town itself.
* GiantEyeOfDoom: One of Pennywise's forms in the Derry sewers is a giant eye, as seen in The Crawling Eye. [[spoiler:Eddie drives it back by spraying it with his asthma inhaler and claiming the liquid is battery acid; a direct comparison to the medicine's taste when he uses it. In reality, his inhaler is a placebo, water with a dash of camphor, prescribed to Eddie in order to placate his mother who uses guilt and Munchausen Syndrome by Proxy to keep Eddie under her thumb.]]
* GiantSpider: Its true visible human form.
* GilliganCut: Used frequently to jump between the adult and child sections of the novel.
* GlamourFailure: Most of Its forms are overtly supernatural while the Pennywise/Bob Gray persona is meant to pass as a normal man in a clown suit, but there are always giveaways that something is wrong with "him," such as a total lack of a shadow, color-changing eyes, and a habit of doing things gravity shouldn't allow.
* GodIsDead: The Turtle created the universe (because of a stomach ache). [[spoiler:Later, it's revealed that the Turtle died in the thirty-year time gap. The cause? It merely choked on a few galaxies it couldn't belch up.]]
* GoMadFromTheRevelation: A common reaction upon seeing [[spoiler:It's true form.]]
* GondorCallsForAid: In the movie when IT returns and the now adult Mike calls the rest of his lucky 7 The Losers Club.
* GreatGazoo: Pennywise is a malevolent form of this trope. Wacky, powerful, and completely evil and murderous, and invisible to most people.
* GrowingUpSucks: Childhood power is strongly rooted in how temporary it is, and no matter how well one might hold onto it, childlike wonder is doomed to fade in the end. Ultimately symbolized in the book by the explosion of the hallway that connects the children's library to the adults' library, never to be rebuilt, and eventually the people of Derry forget that the two buildings were ever connected.
* GroupHug : In both the book and the movie. The group draws strength from it.
* HeroOfAnotherStory: Vincent "Boogers" Taliendo, an old grade-school chum of a few of the Losers, is still in Derry in 1985. As the town begins to crumble, he heads for the hills; King tells us "his journey to the Derry town limits and beyond would make a saga in itself....suffice it to say that he did eventually get out of town."
* HoistByHisOwnPetard: Butch Bowers, Henry's father, who already hated Will Hanlon, Mike's father, for being black, was pushed over the edge when Will started undercutting Butch's produce prices (Will was mainly able to do this because unlike Butch he was a competent farmer and not a lazy dumbass). In retaliation Butch poisons all of Will's chickens. He would have most likely gotten away with it as a jury of Derry's citizens probably wouldn't care that Butch had killed some [[NWordPrivileges n***'s]] chickens, but Butch decided to go the extra mile and paint a swastika on the chicken coop as well, and they ''would'' bring him up on charges for that little shenanigan, what with UsefulNotes/WorldWarII being quite fresh in everyone's mind. So Butch has to pay for the value of the chickens, and he has to sell his prized Mercury automobile in order to afford it.
* HopeSpot: Eddie Corcoran ''almost'' gets away from It...then he trips over a bench, pushed over by vandals that was hidden in the grass.
** When the now grown up Losers find out IT is still alive and is getting back to eating children, the last thirty odd years become this.
* HumanoidAbomination: Its favorite form is [[MonsterClown Pennywise the Dancing Clown]].
* IfYouKillHimYouWillBeJustLikeHim: Of a sort. Mike is only stopped from killing Henry because he realizes that if he does so, he would be a pawn of It just like Henry.
* ImNotAfraidOfYou: How the Losers manage to defeat It once and for all.
* InCaseYouForgotWhoWroteIt: A surprisingly rare example for a Creator/StephenKing adaptation, probably because the title on its own is extremely generic.
* InformedJudaism: An early chapter describes the home where Stan Uris lived as an adult. There is a key-board that was given to the family as a present "2 Christmases ago". Granted, it might have been a generic 'holiday' gift from a Christian friend, but it's really old that Stan's wife would describe it that way, instead of saying that it was given to them around Hanukkah. His wife Patricia also tries to assure Stan that he is not a "klutz" (meaning he's not stupid instead of not clumsy) when the actual Yiddish word for a fool is "yutz" and a Jewish person is unlikely to confuse the terms. Many of Stanley's other behaviours (he admits that his family sometimes eats ham, and when he was about 12 years old he still didn't know what 'kosher' meant) seem at odds with a Jewish upbringing. His pals at the Loser's Club sometimes even forget that Stan is a Jew. When a friend suggests using a crucifix to warn off a supernatural creature Stan gets mad and says it won't work for him, but never considers that a symbol of the Jewish faith (such as a Star of David) might grant him protection.
* JerkassHasAPoint: [[MyBelovedSmother Mrs. Kaspbrak]] usually doesn't let Eddie do anything, because she lives in terror of him dying of illness or injury. In the case of the shoe store X-ray machine, however, she was quite correct when she screamed at Eddie that those things give you cancer.
** Actually no, she is still being over the top even in this case. While it can certainly be argued that regular exposure to ionising radiation is something that should be limited, there is little evidence fluoroscopes 'gave you cancer'. Only one salesperson - people using and demonstrating these machines for ''years'' - has been confirmed as developing cancer. This was a BCC (basal cell carcinoma) of the foot and could easily have happened whether he was exposed to radiation or not.
* KarmaHoudini: Victor "Boogers" Taliendo is a minor bully, and not a true member of Henry Bowers' gang. He spends most of his life in Derry and works as a janitor after he finished school. He has a few close calls when the flood starts, but ultimately makes it out alive.
* JerkWithAHeartOfGold: Mr. Keene, the drugstore owner. He certainly is not a nice person [[spoiler:but feels it is right to inform Eddie that his asthma medicine is simply a placebo.]]
* KickTheDog: A literal example; Henry poisons Mike's dog ForTheEvulz. Followed by a righteous TheDogBitesBack moment during the "apocalyptic rock fight." While chasing and taunting Mike, Henry reveals that he killed Mr. Chips. [[spoiler: The Losers' Club, all seven, who've all had run-ins with Henry by that point, pelt Henry with rocks until he gives in. Henry stays out of the Barrens from that point forward.]]
* LaserGuidedAmnesia: The members of the Losers Club all suffer Derry-related amnesia after defeating IT in the 50's and leaving Derry. The exception is Mike, who stuck around town.
* LaserGuidedKarma: Eddie Corcoran's stepfather, Richard Macklin, beat his little brother Dorsey to death and then pretended he fell off a ladder. While Richard didn't kill Eddie (that was courtesy of IT as the Creature from the Black Lagoon) he's a prime suspect when Eddie disappears, and the authorities launch an investigation into what ''really'' happened to Dorsey. Richard is found guilty of the murder of both his stepsons, spends years in prison and eventually commits suicide.
* LaughThemselvesSick / LaughingMad / TensionCuttingLaughter : The Losers laugh a lot, because Richie is the ClassClown, but noted in the book as a response to terror.
* LetsSplitUpGang: Subverted. When Bill and Richie are exploring the basement of the house on Neibolt Street, Bill starts to suggest this. Richie cuts him off with a resounding "Fuck that!"
* LikeParentLikeSpouse: A rather dark example. Beverly had an abusive father, and later went on to marry a man who also abused her. Sadly, this is TruthInTelevision for many real-life abuse victims.
** Eddie Kasprak's mother and wife are also an example, although the abuse is more emotional in their case.
* LineOfSightName: [[spoiler:Tom Rogan]] uses one of these after arriving in Derry.
* LoadBearingBoss: [[spoiler:A flood destroys Derry not long after It's death. It's implied that It was allowing the town to exist in exchange for providing IT victims every 27 years.]]
* LuckySeven: The last third of the text uses seven as a motif, in that for their particular "magic" to work, the Losers Club has to have all seven members present, or their bond isn't as strong. In the film version, they refer to themselves as "Lucky Seven."
* MagicalClown: Pennywise the Clown is [[spoiler:an EldritchAbomination who shape-shifts to feed on people's fear]].
* MamaBear: Mrs. Kaspbrak, described in almost these exact words, [[spoiler:when Eddie is in the hospital after Henry breaks his arm.]]
* ManChild: Adrian Mellon is described as "rather childlike." Henry never really progressed past the twelve-year-old bully. And IT describes Ben, Bill and Richie as "boy-men" during their final confrontation.
* MindRape: Pennywise is very fond of messing with the Losers Club's heads.
* {{Misblamed}}: An in-universe example; Henry is accused of committing all the murders in the Summer of 1958, when in reality, [[spoiler:the only person he actually kills is his own father]], but his sanity is so far gone by that point that he doesn't fight the charges.
* MisfortuneCookie: After the Losers have dinner at a Chinese restaurant, they get freaked out when the fortune cookies crack open to reveal all sorts of horrible things inside.
* MonsterClown: Pennywise, a ''literal'' monster in the form of a clown.
* MorphicResonance: Several of Its forms have orange pom-poms.
* MostWritersAreWriters: Bill Denbrough grows up to be a horror writer. Bev's friend Kay [=McCall=] is an author of feminist non-fiction.
* MuggingTheMonster: Henry and his pals ambush Ben, but it results in a vicious fight in which Henry takes almost as much punishment as Ben.
* MyBelovedSmother:
** Eddie's mother is a quintessential example, to the point where she's convinced her non-asthmatic son has asthma, leading to the pharmacist giving him a placebo-filled inhaler and outright telling him she doesn't want him to have friends aside from her.
** Ben's mother is a less dramatic example, but she feeds his obesity by making him huge meals and gets offended when Ben tries to cut back on the food. He eventually realizes that giving him all the food he could eat was his mother's way of proving to herself that she could provide for her son. He loses weight by asking her to make a bunch of salads, then praising them to the sky- he eats healthier, she gets the self-esteem boost.
* MythologyGag: When Richard Macklin is convicted for the murder of his stepson Dorsey, he is sent to [[Literature/DifferentSeasons Shawshank State Prison]].
** During the reunion lunch, Mike contrasts Derry's violent proclivities by mentioning "[A] medium-sized city in Texas where the violent-crime rate is far below what you’d expect for a city of its size and mixed racial make-up." It's a reference to La Plata, the town at the epicenter of the "calmquake" in the ''Literature/NightmaresAndDreamscapes'' story "The End of the Whole Mess."
** Ben's list of movie vampires that Pennywise's Dracula looks nothing like includes Reggie Nalder. His vampire role was in ''Salem's Lot''.
* NobleBigotWithABadge: The cops interrogating the young men that assaulted Adrian Mellon, a gay man, throwing him off a bridge and into the Derry canal to his death (at the hands of Pennywise), would love nothing more than to see the local gay bar close its doors for good. However, they react with anger and disgust at the brutal way in which Mellon was beaten and they look forward to throwing the book at the three punks who did it.
* NWordPrivileges:
** A variant on this in that the Loser's Club all have "N-word privileges" with respect to each other. Thus, it's okay for a member of the club to make fun of Stan for being Jewish or Ben for being fat or Bill for his stutter, but God help any outsider who does the same thing.
** Averted in the literal sense, which Richie does add a rather inappropriate (by today's standard, if not that of 1958) southern black caricature voice to his repertoire after Mike's arrival, he does it good-naturedly, not out of maliciousness, and none of the Losers even use the actual N-Word directed at Mike.
* NonIndicativeTitle: [[spoiler:An odd example. "It" is actually female (and pregnant).]]
* NothingIsScarier
* OfficerOHara: Mr. Nell, who provides the basis for Richie's "Irish Cop" Voice.
* OffingTheMouth: Richie Tozier is a largely involuntary DeadpanSnarker who must mock others whenever he notices something he can mock people for, and this is the reason Henry Bowers is out to get him, and along with the others of the Losers, out to kill him.
* OneSteveLimit: Averted with Eddie Corcoran and Eddie Kaspbrak. Bill also (presumably) shares the name "William" with Michael Hanlon's father, though he goes by "Will."
* ParentalIncest: Implied that this is what Beverly's father wanted to do to her (especially during the scene in which [[spoiler:Mrs. Kersh turns into a witch and then into her father (provided that IT was not just messing with her and was channeling the truth).]] Earlier on, Beverly's mother asks her if her father ever touched her (which Beverly doesn't understand).
* ParentalObliviousness: None of the children's parents are aware of what's happening in Derry.
* PhraseCatcher: Beep beep, Richie.
* PlaceboEffect: Eddie's asthma is revealed to be psychosomatic, and his medication is a placebo.
* PoliceAreUseless: The Losers don't even bother to go to the cops because they are smart enough to know they won't be any help. Also invoked by Mike's father after Henry attacks him and drenches him head to toe in mud; Mike's mother demands he call the cops, but dear ol' Dad doesn't do so because he doesn't care for the police chief Borton and views him as a spineless jellyfish who won't side with him.
* PoliticallyIncorrectVillain: Pennywise himself, along with Henry and Butch Bowers. Ditto for Adrian Mellon's murderers.
* ThePowerOfFriendship: One of the major themes in the book is of childhood friends who have long since gone their separate ways but must now come together to defeat the BigBad.
* {{Pride}}: Pennywise's biggest weakness overall. After centuries It never bothered to learn its own limitations or vulnerabilities or to take its own victims seriously. Even after establishing firmly that, possibly for the first time ever, the "food" has decided to fight back, a fairly obvious possibility when hunting sentient prey, It does absolutely nothing about the problem. It just lets them walk right up to its home, safe in the belief It can take them all with no trouble, and gets curb stomp into another thirty years of hibernation.
* ProductionForeshadowing: In the story "Gray Matter" from his book ''Literature/NightShift'', King tells us about a sewer worker who went down into a pipe one day and allegedly saw "a spider as big as a good-sized dog settin' in a web full of kitties and such all wrapped up in silk thread."
* RatKing:
-->"A litter. Biggest litter I ever saw...''anyone'' ever saw, probably...Their ''tails''...they were all tangled up, Bill. Knotted together. Like snakes."
* RealMenWearPink: Henry Bowers wears a pink motorcycle jacket in the book. A fourth grader who is foolish enough to laugh at it loses three of his front teeth.
* RedOniBlueOni: [[spoiler:The Spider and the Turtle. One actively hunts down and eats human children while the other just sits on the edge of forever, seeing it all happen and "helping" the Losers during their first confrontation with It. The Spider berates it for just sitting there, offering seemingly useless advice. That the Spider's eyes are described as ruby-red while the Turtle's shell is some blueish-greenish color also reinforces the trope.]] Arguably, the brash and heroic Bill, Beverly, and Richie, against the more reserved Mike, Eddie, and Stan. Ben fits somewhere in the middle.
* TheReveal: The revelation, in the book's later chapters, that IT [[spoiler:is actually female. Not only that, but she just so happens to have [[OhCrap laid a shitload of eggs...]]]]
* RippedFromTheHeadlines: Adrian Mellon's murder was modelled after the murder of Charlie Howard, another CampGay man who was thrown off a bridge in Maine; they even landed in the same river. Howard simply drowned, though; there was no demonic clown involved. Probably. Also The Brady Gang (changed to Bradley in the text), [[http://en.wikipedia.org/wiki/Al_Brady gunned down by FBI agents]] in Bangor in 1937.
* SacrificialLamb: George Denbrough and Adrian Mellon.
* SayMyName: ''"BEEEEEEEEEEV!"''
* ScareEmStraight: In 1957, Ben borrows a trashy book called ''Roadblock''. The librarian mentions that, thanks to its use of a melodramatic SurpriseCarCrash, she normally gives it to teenagers who've just obtained their driver's licenses to scare them into obeying the speed limit. According to her, it seems to work.
* ScrewThisImOuttaHere: Mike mentions that there are a ''lot'' of families who move out of town when the cycle starts and they realize just how bad the evil in town can get.
* ShapeshifterModeLock: Once Pennywise assumes the shape of its victim's greatest fear, it has to follow all the "rules" of that shape, whether it wants to or not. ''And it cannot change form to something else once everyone who sees it has "agreed" on what it is.'' For example, when Pennywise confronts the kids in the house on Neibolt Street, Richie Tozier screams out that its "THE TEENAGE WEREWOLF!", a movie-monster that he is terrified of. The other kids, who had been seeing Pennywise as various ''other'' monsters, immediately saw it as a werewolf as well. And once it was a werewolf, it became vulnerable to the silver slugs Bev was shooting at it with the slingshot.
** Notably averted with [[spoiler: Patrick Hotstetter]]. When IT appears, because the character has been described as a sociopath bordering on true psychopathy, his emotional responses are muddy at best. Because there's nothing that really scares this character, IT appears with a face like running wax and a rotting, burbly voice. This is somehow scarier.
* ShoutOut: ''[[Film/TheWizardOfOz Bowers and Huggins and Criss (oh my)]]''.
* SilverBullet: At one point [[ClapYourHandsIfYouBelieve the Losers use belief to make their weapons into silver bullets]] to hurt IT when it tries to attack them in the form of a werewolf.
* TheSmurfettePrinciple: Beverly is the ''only'' girl in the Losers Club.
* SpannerInTheWorks: Pennywise's own impatience and arrogance serves as this for him. In addition, he further hampers himself by breaking down and terrifying his prey, ensuring they won't go anywhere near the sewers. For example, he almost gets Bill into the sewer treatment plant by impersonating his father, but when Bill hesitates, he turns into a rotting corpse and grimly remarks on how they're all floating down here; Bill promptly freaks out and runs away. [[FridgeLogic This is because meat flavoured with fear tastes better.]]
* SpeedSex: Beverly's friend, Kay [=McCall=] (a feminist writer) says this about [[GoldDigger her ex-husband]]: "Two pumps a tickle and a squirt, that was ole Sammy's motto. The only time he could keep it up for longer than seventy seconds was when he was [[ADateWithRosiePalms pulling off in the tub]]."
* SpookySilentLibrary: At least when Mike's working there after hours.
* SpookyPhotographs: That start moving and threatening you. And they bleed.
* [[DrinkingGame/StephenKing Stephen King Drinking Game]]: Probably the highest scoring of any of King's work.
* SurvivalMantra: "He thrusts his fists against the posts and still insists he sees the ghosts," Bill's anti-stuttering and [[spoiler:anti-It]] phrase.
* SympathyForTheDevil: One of the reasons why [[spoiler:Mike can't quite bring himself to kill [[JerkAss Henry Bowers]]]] in self-defense. [[spoiler:Mike]] pities him for having grown up under [[spoiler:[[AbusiveParents someone like Butch Bowers]]]], who naturally heavily influenced [[spoiler:Henry's]] way of thinking and was partially responsible for his son's racism and jerkassery. And that Mike would be doing Its work.
* TakeThat:
** In the book, the adult Richie's reason for agreeing to fight IT? "It can't be any worse than interviewing Ozzy Osborne."
** In the novel, when Bill ([[AuthorAvatar who, as an adult becomes a very successful horror writer]]) recalls his college years, and how he crashed heads with his writing teacher, who believed that a good work of fiction [[AuthorTract also had to make a political statement]], and Bill's statement that one should write good stories that entertain, since "politics change over time but stories remain."
* ThereAreNoTherapists.
* ThereIsNoKillLikeOverkill: The execution of the Bradley gang.
* TownWithADarkSecret: More like a dark secret shaped like a town.
* TrueCompanions: The Loser's Club.
* TurtlePower: [[spoiler:Hinted at throughout the book. A cosmic force, opposed to It in at least some way, is called the Turtle. It subtly guides the protagonists and, according to It, created the universe when it got sick and threw up.]]
* VoluntaryShapeshifting: IT usually takes the form of Pennywise the Clown, but often assumes the shape of whatever the victim is most afraid of. Pennywise is something of a neutral form for either dealing with multiple victims or the same victim twice, or just getting around.
* WeaksauceWeakness: It, an EldritchAbomination in the extreme, can be staved off by...a child believing that water in his inhaler is battery acid, or, in one case, Beverly mentioning grackles, a particular kind of bird. It's [[JustifiedTrope justified]] in that It deliberately uses what children fear most to scare them, which has been an effective tactic for centuries. The Losers' Club were the first children to actually ''fight back'', so it's naturally completely unused to the idea of defending Itself.
* WhatHappenedToTheMouse: In the book, Eddie Kaspbrak was married to a woman named Myra. She is never told what happened in Derry; not even [[spoiler: the death of her husband is revealed.]]
** [[spoiler:Tom Rogan's death]] is treated with almost casual brevity, so much so that some readers (especially those suffering from mild EndingFatigue) may be left wondering what happened to him.
* WhamLine : [[spoiler:"IT was not male. IT was female. And IT was pregnant."]]
* WhereEverybodyKnowsYourFlame: Parodied - it takes the guy running The Falcon ''years'' to realize that his place has become the town's gay bar, but everyone else is convinced there must be orgies going on nightly.
* WhyDontYouJustShootHim: There are plenty of times in the story where It has one of the Losers cornered or alone but doesn't kill them. For that matter, it would be child's play for It to enter the kids' houses through the sewer system and kill them in their sleep. The story implies that It doesn't do this for two reasons: 1) It feeds on their fear, and 2) It has fun coming up with different guises and ways to psychologically torment them.
* WorstNewsJudgmentEver: Mike discovers that despite the children's killings and incidents in which many people die, those news are rarely spoken outside the town of Derry; it's like ''something doesn't want those to be known outside''.
* WouldHurtAChild: It won't just hurt kids, but psychologically torment and ''eat'' them too. In fact, Its introduction scene, where It lures little George Denbrough to a sewer grate and rips the poor kid's arm off at the shoulder says everything we need to know about just what kind of a monster It truly is.
* YouCannotGraspTheTrueForm: In addition to It assuming various guises to make children afraid and thus taste better, this is also implied; seeing Its true form can ''completely destroy someone's sanity.'' When the Losers' Club battles IT, the "true form" they see--a GiantSpider--is said to be their minds desperately trying to make sense of the horrible being, and a massive arachnid is as close as they can get.
* YouCantFightFate: It's heavily implied that everything that happens during the Losers' battles with It, or at least a significant portion of events, are predestined.
* YourCheatingHeart: [[spoiler: Bill and Beverly have sex as soon as there's an opportunity when they meet up again in 1985. In Beverly's case it's understandable, since she's just escaped from her abusive husband, but Billy is happily married!]]
* YourMindMakesItReal: Which It learns can be a two-edged sword: "This is battery acid, you slime!" [[spoiler:Doesn't work nearly as well for Eddie in 1985, as IT quickly kills him when he sprays his aspirator.]]

''"You don't have to look back to see those children; part of your mind will see them forever, live with them forever, love with them forever. They are not necessarily the best part of you, but they were once the repository of all you could become."''
