-> ''"[The wizard] jumped down, and started waving his arms around while he went to speaking and squealing in one of those languages wizards use so the rest of us will think there is something terribly strange and mystical about what they do, kind of like lawyers."''
-->-- '''Murgen''', ''Literature/TheBlackCompany''

A version of FunctionalMagic where spells are cast by [[BeCarefulWhatYouSay speaking]] in a particular language. Can be WordsCanBreakMyBones or IKnowYourTrueName taken to the N[[superscript:th]] degree, where ''every'' word in the language is a "true name", but this need not be the case for it to be a language of magic.

BlackMagic is often paired with BlackSpeech, WhiteMagic is often in [[OurAngelsAreDifferent Angel song]]. In works set on Earth, the language may be a real-but-now-dead one, such as [[AltumVidetur Latin]]. The words are often written in the Old Norse [[http://en.wikipedia.org/wiki/Runic_alphabet runic alphabet]]; HermeticMagic can use a number of real-life occult alphabets, such as Enochian or Paracelsus' Alphabet of the Magi, instead.

WordsCanBreakMyBones and IKnowYourTrueName are subtropes. May be the backbone of a MagicalIncantation. If consistently SUNG to make it magic, that's MagicMusic.

!!WordsCanBreakMyBones examples:


* The horned denizens of the moon Wreath in ''ComicBook/{{Saga}}'' speak in this language which is both their native tongue and the means of using magic. Interestingly, this language is always represented in text in a light blue font and is literally '''called''' "Blue."

* ''FanFic/TheApprenticeTheStudentAndTheCharlatan'' has two instances.
** First is a precursor to modern Equestrian magic, where magic was spoken through spellwords. It functions as a ShoutOut to ''Literature/TheInheritanceCycle'' as the language in question is referred to as "an ancient language" and the one word we see used is lifted directly from it.
** The second, which appears to be the "written" form of the above, is the language of spells, used to arrange traps or other enchantments. It doesn't have a script, but the characters all treat such spells as though they had a language of their own that could be manipulated to do what they want.

* The elven language in ''Literature/InheritanceCycle''. Want a big fire or an explosive arrow? Just yell "Brisingr!" and you're all done. The name of the language itself allows one to control how it is used.
** At one point, a MrExposition character explained that back in the beginning of the world, magic was ''purely'' based on intent and no words were attached. But the "Grey People" did some epic thing that permanently tied the magic of Alagaesia to words, in order to make magic more controllable.
** There is a handy dictionary in the back of the book that lets people try to speak it: the ancient language does not at all roll off the tongue. Kinda makes it much weirder when we learn that the entire elven race speaks it on a daily basis.
*** If the "Ancient Tongue" looks that difficult, you need to [[http://en.wikipedia.org/wiki/Ubykh_language look around more.]]
** The language isn't that hard if your native tongue is Swedish or Norwegian. Also, Finnish, Estonian and Hungarian get an easy ride, though they pronounce the words differently.
** Subverted in that [[OurElvesAreBetter the elves]] use this language for normal conversation. See, if you don't actively put any magic behind the words, then its only power is being a LanguageOfTruth.
* The Speech in the ''Literature/YoungWizards'' series. A spell consists of talking to the Universe using the Speech, first saying what you want to happen and then saying how you want it to be accomplished. The Speech can also be used as TranslatorMicrobes, but not the most convenient type -- people who don't know the Speech will automatically hear their first language when it's spoken, so, for example, a European wizard working in Africa might surprise {{Muggles}} when he not only appears to be speaking several languages he shouldn't know, but also speaking all of them simultaneously.
* In the ''Literature/{{Earthsea}}'' series, magic works exactly like this. On the negative side, screwing up can result in TheEndOfTheWorldAsWeKnowIt fairly easily. That's why wizards avoid doing anything as much as possible. The language of magic is also the language of dragons (somehow, they avoid reshaping reality every time they lie). The True Speech is a LanguageOfTruth to humans, but dragons can and do lie in it. From ''A Wizard of Earthsea":
--> ''Although use of the Old Speech binds a man to truth, this is not so with dragons. It is their own language, and they can lie in it...''
** We have to note that dragon lying is closer to HalfTruth and other forms of non-lying deceit than direct fibbing. You see, the way in which it is a language of truth is not that one cannot lie in it, but rather that [[RealityWarping reality changes to make the statement true]] (with [[RealityWarpingIsNotAToy devastating effects]], since everything--every pebble, every twig, every drop of water--has a name, which it might share with other things)... The dragons' ability to lie in it thus has more to do with their deep knowledge of the language than any specific power they have.
* The Divine Language in ''[[VisualNovel/FateStayNight Fate/stay night]]'', spoken by Servant Caster, which allows her to summon plague winds or 'rains of light' (read: [[BeamSpam lasers]]) with a single word. Represented by Ancient Greek, but supposedly, it's cannot be pronounced by modern humans (which was probably a problem when they were making the voiced edition). The Fairy Letters written on [[WaveMotionGun Excalibur]] also count.
** Also from the Franchise/{{Nasuverse}}, the [[LightNovel/KaraNoKyoukai Unified Language]], which was 'spoken' to another plane altogether; it allows for the retrieval of a soul's 'recordings', essentially giving access to all knowledge possessed by every human being in existence.
* In the Literature/KateDaniels universe, once a word of power is acquired, the mage can command other people and objects just by saying the word, which translate to such things as "Release" and "Obey". However, words of power are acquired by having a contest of wills with the word, and most mages die rather than mastering its power. At the end of ''Magic Bites'', the BigBad reveals himself to be fluent in the language from which all words of power were taken.
* In Creator/RobertEHoward's Literature/ConanTheBarbarian story "Literature/ShadowsInTheMoonlight", [[DreamingOfTimesGoneBy Olivia dreams]] that the incantation "Yagkoolan yok tha, xuthalla!" is used by a PhysicalGod to [[TakenForGranite transform his son's murderers to statues]]. (It appears harmless when recited by a parrot, though.)
* Inverted in Literature/TheDresdenFiles, where Practitioners use ancient languages as verbal foci for their magic ''to insulate their brain from the energy they're channeling''.
** Harry uses a bastardized Latin (which would be bad for him if he ever actually learned Latin properly - which he's supposed to because it's the common language of wizards), though others have used Egyptian dialects and Oriental languages, among others. Harry and other "low-level" wizards also have to actually vocalize. When members of the Senior Council use magic, they don't say a word, and it's extremely creepy.
* In Heinlein's Literature/StrangerInAStrangeLand, the Martian language works sort of like this. Knowing fully (grokking) the language allows powers like telekinesis, total annihilation of people, and stuff.
* In Rick Cook's Wizardry series, the Language of Magic is a ''programming'' language. In later novels, subcontractors are hired to improve the OS.
** More comprehensively, the Language is equivalent to a genetic code in which spells naturally self-assemble, evolve, and at higher levels of complexity assume physical incarnations and utilize lower-level beings the way we contain our own flora and and fauna. Likewise, things of magic respond to human activities to varying degrees of complexity. The key realization was that a specific set of enzyme-equivalents have ''predictable'' behavior (most don't) and which can combine to form logic gates, allowing spells to be constructed using programming techniques rather than lethal trial-and-error or bargaining with magical creatures. Most of the human-usable Language of Magic is ''not'' suitable for programming in, and it's noted repeatedly how different constructed spells feel from the natural variety.
* In ''Literature/TheBrokenCrescent'', all magic takes place via the Language of the Gods. Speaking or writing in this language intrinsically causes magical effects. Nick Black, the hero, is able to perform great feats of magic once he deciphers the syntax and structure of it.

* In ''Series/{{Doctor Who}},'' we get Old High Gallifreyan, the lost language of the Time Lords.
--> Eleventh Doctor: "There were days...many days, when those words could burn stars and raise up empires and topple gods."
** Then subverted and PlayedForLaughs:
--> Amy: "So what do these words say?"
--> Doctor: [[ArcWords ''Hello Sweetie.'']]

[[folder:Other Sites]]
* ''Wiki/SCPFoundation'', [[http://www.scp-wiki.net/scp-1220 SCP-1220 ("Logos")]]. The individual words and phrases in the language SCP-1220 can affect reality within 10 meters or so of the speaker. For example, if someone says the word "fire" in that language something nearby will catch on fire. If the word "rain" is spoken then rain will begin to fall.

* ''Franchise/TheElderScrolls''
** Nirn's [[OurDragonsAreDifferent dragons]] are the [[DragonsAreDivine divine children]] of the [[TopGod chief deity]] of the [[SaintlyChurch Nine Divines Pantheon]], Akataosh, the Dragon God of Time. (They also may be fragments of his actual being, and serve of a role similar to being [[DragonsAreDemonic very destructive]] [[OurAngelsAreDifferent angels]].) They inherently speak a Language Of Magic which gives them small scale [[RealityWarper Reality Warping]] powers. Essentially, they "make real" whatever they speak in this language. For example, when a Dragon is "breathing" fire, they're technically commanding fire to come into existence, and battles between dragons are essentially [[WordsCanBreakMyBones very loud debates]].
** In the ancient past, the dragons and their [[ReligionOfEvil Dragon Cults]] took over much of Skyrim. Seeking a way to defeat the Dragons and their Cults, the ancient ProudWarriorRace [[HornyVikings Nords]] prayed to the [[OurGodsAreDifferent Divines]] for aid. Their prayers were answered and they were taught how to use the language of the Dragons themselves, which they called the Thu'um (or the "Voice"). Led by the Tongues, masters of the Thu'um, the ancient Nord armies vanquished the dragons and their Cults, then forged an Empire that covered nearly all of north Tamriel. A succession crisis would eventually tear it apart, and then the use of the Thu'um as a weapon of war dropped dramatically after their [[ShockingDefeatLegacy defeat at the Battle of Red Mountain]], following which one of those Tongues (Jurgen Windcaller) [[HeelFaithTurn founded the "Way of the Voice" to use the Thu'um only honor the gods]].
** In modern times, the Greybeards continue to follow Windcaller's "Way of the Voice." They live in a monastery known as High Hrothgar near the top of the [[TheTower Throat of the World]], the tallest mountain in Tamriel. So powerful is their Thu'um that they are usually sworn to silence in order to not [[PersonOfMassDestruction destroy everything around]] them simply by ''talking''. Even their faintest whispers are known to shake the mountain on which they live. They Greybeards accept anyone who wishes to learn the Thu'um and follow the Way of the Voice. It is explained that [[CharlesAtlasSuperpower anyone can learn to use Thu'um]], but it takes a great deal of training, mostly to learn the true ''meaning'' of the words in the shout. Anyone can try speaking it, but you need to put your ''soul'' into it for magic to happen.
*** How powerful are the Greybeards' voices? When they called Wulfharth, the [[WhoWantsToLiveForever immortal]] EternalHero[=/=][[GodInHumanForm possible avatar]] of [[TopGod Shor]], to High Hrothgar, they blasted him to dust just to show him [[spoiler:what it will be like when he gets betrayed by [[TheConqueror Tiber Septim]]]].
** ''[[VideoGame/TheElderScrollsVSkyrim Skyrim]]'' is the first game in the series in which the Thu'um is seen in action. The PlayerCharacter is a legendary Dragonborn (or Dovahkiin), a rare mortal blessed by Akatosh with the immortal Aedric soul of a dragon. Akatosh creates those who are Dragonborn to be the [[HunterOfHisOwnKind natural predators]] of the Dragons, being capable of ending their ResurrectiveImmortality by [[YourSoulIsMine absorbing their souls]] and using those souls to increase their mastery of the Thu'um. After being revealed as a Dragonborn, he/she will be summoned by the Greybeards to High Hrothgar for training. When they call for the Dragonborn, ''all of Skyrim'' can hear it.
** Others in ''Skyrim'' are revealed to be able to use the Thu'um as well. Ulfric Stormcloak, [[RebelLeader leader of the Stormcloak rebellion]], studied with the Greybeards and used the Thu'um to win his duel with High King Torygg, kickstarting the Skyrim {{Civil War}}. Additionally, many of the [[OurZombiesAreDifferent Draugr]] EliteMooks (the ones with the words "death," "over," or "lord" somewhere in their names) were the leaders of the ancient Dragon Cults and can use the Thu'um as well. Miraak, [[spoiler:the ''first'' Dragonborn and BigBad of the ''Dragonborn'' DLC]] as well as the BonusBoss Ebony Warrior can also use the Thu'um.
** ''[[VideoGame/TheElderScrollsOnline Online]]'' introduces Daedric Titans, dragons who have been corrupted by [[GodOfEvil Molag Bal]], the [[OurGodsAreDifferent Daedric Prince]] of [[TheCorrupter Domination and Corruption]]. While stated to be only a "crude imitation" of the "true" Thu'um, Titans possess the ability to speak a spell of flaming essence-drain that can debilitate an opponent with a single word.

* The language of the Sidhe seems to be this in the Literature/WhateleyUniverse, although it's hard to tell since the Sidhe were wiped out millennia ago. (It looks like they're getting better.)
* An unusual example in ''Literature/TrintonChronicles'' is that there are true and half-[[UsefulNotes/FurryFandom dragons]] who learn to speak two different languages, one for magic and one for everyday speech. The magic one is so ancient in fact that even they don't fully know what it means. Most magic users (who we presume were taught by dragons in the distant past and then passed it along) utilize this language to cast spells and call to the universe to change reality in some way. The language has not been written down in the story to keep it's sounds a mystery but is mentioned whenever someone starts to cast spells. Interestingly some magic uses speak their spells in an [[UsefulNotes/EsperantoTheUniversalLanguage odd]] language that only works when adding the word "manu mea" at the start of each casting.
* Ancient phaetonian primal in ''Literature/{{Phaeton}}'' is like this, and the more descriptive you are the more powerful the spell.


!!Other examples:

[[folder:{{Anime}} and {{Manga}}]]
* In ''[[LightNovel/HaruhiSuzumiya The Melancholy Of Haruhi Suzumiya]]'', Yuki casts spells ''by chanting SQL queries sped up and played backwards.''
* In ''Manga/MahouSenseiNegima'', every western mage has a personal [[ByThePowerOfGreyskull magic release key]]. Most [[HermeticMagic western spells]] are spoken in Latin, though some of the higher level ones are done in Ancient Greek. Specifically, the main body of your spell must be an actual phrase in Latin (or Ancient Greek), but the aforementioned "key" can be any random string of sounds that tickles your fancy.
** In addition; the BigBad [[spoiler: has an ability called "Code of the Lifemaker: Rewrite", which literally allows him and his minions to [[RealityWarper rewrite the reality]] of the magic world at will. Seeing as he may have ''created'' it to begin with, it makes sense that he can modify it as he pleases.]]
** The only divine magic we've seen so far was in ancient Japanese.
** By contrast, most Eastern magic is based on Sanskrit letters, who have individual meaning but are combined in ways that do not form proper words.
** However, the magic ''writing'' in the series is in the relatively ([[UsefulNotes/{{Armenia}} and]] [[WouldBeRudeToSayGenocide sadly]]) obscure Armenian language. %% I actually learned about the Genocide through my love of language. If people are interested in the language the often become interested in the history. I've done what I can to spread awareness and will continue to do so.

* The [[UsefulNotes/TheGoldenAgeOfComicBooks Golden Age]] hero Zatara, and later his daughter ComicBook/{{Zatanna}}, cast spells by speaking backwards. More specifically, the individual words are spoken backwards, but the sentence structure is still spoken forward.
* Most magic spells in Creator/DCComics work this way, at least when used by ComicBook/ThePhantomStranger and his supporting cast.
* ''Editor Girl'', also known as ''Kris Simon'' from the Shadowline-Image comic imprint. Actually, she can't use her own voice, but she has to use a magic pen to ''edit'' whatever her opponent is saying (LeaningOnTheFourthWall, that's usually portrayed as Editor Girl correcting people's speech bubbles with her pen). The revised edition of her opponent taunt becomes reality: for example, editing "You'll face my gun, Editor Girl" in "You'll ''take'' my gun, Editor Girl" results in Kris' opponent getting the urge to surrender his weapon.
* Zigzagged with Comicbook/DoctorStrange, who can cast spells with simple English commands, lengthy rhyming English invocations, or words and phrases which are definitely not English. Of course, he's explicitly a Master of the Mystic ''Arts''.

* Generally speaking, one does not need a special language to work magic in Creator/TamoraPierce's ''Literature/TortallUniverse.'' However, the most powerful spells are written in "old Thak," the dead language of a VestigialEmpire, and there are also "Words of Power" which are generally unpronounceable and only pulled out for ''very'' special occasions.
* In the ''Literature/HarryPotter'' series the vast majority of spells consist of [[CanisLatinicus Latin words]], and it would seem that knowing Latin makes it easier to develop certain types of spells. However, there's little mentioned about where spells come from or how they're made.
** The Hindi version [[{{Woolseyism}} translated it as classical Sanskrit]].
** Strangely in book 4 there's a passing reference to Hermione inventing a spell whose incantation is in English.
** Every spell has an incantation, most of which are in Dog Latin, others in some distortion of English, Hebrew, or Arabic. While a talented wizard needn't say the incantation aloud to cast the spell, he certainly needs to know it. It's unknown how spells become connected to their incantations, however. What is known is that new spells are still being invented, and that it takes tremendous magical talent to do so, so it's not as simple as picking a word to describe the effect you want.
** Witches and wizards can do a little magic through sheer force of will, without words or wands (though it's very imprecise), and the intent or mood of the caster is a factor in some wand-cast spells. Because of this, some fans have theorized that the words in spells are just a method to help the caster focus their will, and that a caster could theoretically cast spells in any language of their choice. But the books strongly suggest that the ''specific'' word will ''always'' cast (or attempt to cast) its assigned spell, regardless of the caster's will. In the sixth book, for instance, Harry successfully casts one spell without knowing what it does beforehand, based solely on its word. And the first book notes that accidental mispronunciations of spells can produce entirely unintended effects.
---> '''Prof. Flitwick:''' And saying the magic words properly is very important too — never forget Wizard Baruffio, who said 's' instead of 'f' and found himself on the floor with a buffalo on his chest.
* In ''Literature/TheElenium'' and ''Literature/TheTamuli'' trilogies by Creator/DavidEddings:
** The language used in the worship of the pagan gods is the LanguageOfMagic, since magic is [[ReligionIsMagic asking the gods to do things for you]].
** This ends up humorous several times. Once, a group is trying to fool peasants with "magic". One character asks the magical instructor what language it is, to which the tutor replies, gibberish. He then asks where Gibbers are from.
** Another instance involved one of the characters speaking directly, in his native tongue, to his patron goddess for light. She chides him for not doing it right, but provides it anyway.
** Finally, one of the members of the primary church muses that they did not need to go outside their own religion for magical assistance, to the horror and chagrin of the other members present.
* ''Literature/TheDresdenFiles'': Harry Dresden doesn't really ''need'' to use the fruits of his Latin correspondence course for his incantations,since his magic works via focus of intent. In fact, in the Dresden universe, it isn't a specific language that's important, but what the words mean to the wizard saying them. Magic words are in a language foreign to the user to insulate their mind from the power. The spell languages are in a language that means something to the user but is still unknown enough to insulate the wizard from his or her own power. You don't want to create a raging inferno by just saying "fire." [[note]] FridgeLogic that he'd use a language with so many nigh-identical cognates in its daughter languages. "Hey, let's take vacation this year in Tierra del [[PlayingWithFire BOOOOOM]]." [[/note]]
* Ian Watson's novel ''Queenmagic, Kingmagic'' is set in a fantasy world based on the game of chess, with black and white kingdoms eternally at war. So it's not entirely surprising that, instead of the usual Latin, the magical language in which their spells are cast turns out to be Russian.
* In Creator/PoulAnderson's ''Literature/OperationChaos'', magic works much more effectively if the caster uses an esoteric language -- esoteric to ''his/her culture'', that is (the hero at one point creates a minor but effective spell in PigLatin). So student mages come to the U.S. from Africa or Asia to learn spells in American street slang. Simple [[TheLawsOfMagic Law of Similarity]], obviously. You can not expect to get extraordinary results from ordinary language.
* In Creator/PatriciaCWrede's ''Magician's Ward'', it's ''insanely'' dangerous to try casting a spell in your native tongue, for reasons partly related to the Harry Dresden example above. The amount of danger increases the further along you get in your magic studies. A first-year student casting a spell in their native language isn't likely to have results that are ''too'' awful, mostly because they are not yet able to use that much power. A third-year student casting a spell in their native language may be dealing with the consequences for weeks.
* In Creator/DanAbnett's ''Literature/{{Ravenor}} Returned'', when Kys infiltrates a decoding process, even the partial decoded stuff is enough to make her ill and betray her. It also lets her learn a "word" that kills men; she uses it to escape. This proves to be Enuncia -- an immensely powerful RealityWarper.
** In ''Literature/RavenorVsEisenhorn'', Enucia is used to test Beta.
* In Creator/JohnCWright's ''Literature/ChroniclesOfChaos'' this is one technique of magic.
* Magic in the ''Literature/SecondApocalypse'' series by R. Scott Bakker uses an original variation on this; the trick to magic is not just speaking in another language, but in saying one string of words while ''simultaneously thinking a second and different string'' (not as easy as it sounds; try it). To make it worse, you have to simultaneously understand the meanings of both phrases; the reason being that the meaning of each phrase somehow clarifies and precisely limits the meaning of the other, creating sufficient mental precision to bring about the desired magical effect.
* In ''Literature/{{Discworld}}'' we never actually hear any magic words after the first book, ''Discworld/TheColourOfMagic'', in which they sound vaguely Arabic mystical-cum-Lovecraft. Later books just cut around the spell scenes. However the AnimatedAdaptation of ''Discworld/SoulMusic'' uses bad DogLatin, probably in reference to all the other settings that use it. "Ovum Krakkus, Totalé Knackus!" (as he breaks the egg).
** There's a tradition of bad DogLatin in ''Literature/{{Discworld}}'' with two examples of it being considered "wizard talk", although neither character was actually casting a spell.
* In ''Literature/TheLordOfTheRings'', Gandalf uses Elvish words when "casting spells", but this is not anything specific to the language itself: being an Ainu, one of the angelic order who sung the world into existence, it makes sense he can change the nature of reality with his voice. Also seen with Tom Bombadil and Lúthien (who was half Ainurin).
** Sauron, also an Ainu, does much the same thing, using an incantation in the BlackSpeech which he had invented to imbue the One Ring with his power.
** It's important to note that some of the 'spells' cast in ''Lord of the Rings'' are not actually spells; rather, they are characters speaking to a spirit. For example, when the Fellowship is suffering under dangerous snowy conditions on the mountain Caradhras, it's because Saruman is telling the spirit of the mountain to crush the Fellowship. Gandalf's 'counter-spell' is him telling the mountain spirit to calm down.
* ''Literature/TheWeirdstoneOfBrisingamen'' uses Latin.
* In Ysabeau Wilce's ''Literature/FloraSegunda'' series, all magick is performed through the language of Grammatica, which also has its own alphabet that readers aren't supposed to understand how to pronounce. Get your grammatica wrong, you get the spell (well, the term used in the books is sigil) wrong. Very skilled adepts (magick users) ''don't'' need to actually speak the words out loud...Lord Axacaya is the primary example of this as of ''Flora's Dare''.
* The magic system in ''Literature/TheLongPriceQuartet'' is based on language. Poets use language to bind their andats, which are abstract concepts made flesh. They use an extremely intricate custom built language to describe the idea they want to capture. They have to describe it perfectly, with absolutely no ambiguity or imprecision, and then hold that definition in mind for the rest of their lives. Failure to be precise enough tends to be [[CruelAndUnusualDeath extremely painful]]. To further complicate matters, once an andat has been bound and subsequently escape, it has to be described in a completely different way to be bound again.
* The Old Speech in Creator/SusanCooper's ''Literature/TheDarkIsRising'' series, spoken by those of both the Light and the Dark.
* In Creator/RobertEHoward's Franchise/ConanTheBarbarian story "Shadows in the Moonlight", a sample from a talking parrot:
-->''Abruptly the bird spread its flaming wings and, soaring from its perch, cried out harshly: "Yagkoolan yok tha, xuthalla!" ''
* The Literature/{{Dragonlance}} series has wizards who, like standard ''TabletopGame/DungeonsAndDragons'' characters, speak magical words in order to activate their spells. However, unlike most verbal components, Dragonlance wizards can use their magical language in actual conversation. According to WordOfGod, the examples used in the books are based on a kind of proto-Indonesian language structure, though the words themselves have no real world equivalent.
** Raistlin Majere, in fact, learned the activation word to the light spell in his staff through extensive trial and error. Finally, in frustration, he blurted out "Shirak, damen du!", which translates as "Light, damn you!". After the staff lit up, he went back and realized that "Shirak" (light) was the keyword, while "Dulak" (dark) was used to cancel the spell.
* Subverted in Awakening, the magic system from ''Literature/{{Warbreaker}}''. While speaking aloud is essential for Awakening, Commands (aka spells) only work if given in the Awakener's own native language. So ''any'' language is potentially magical, as long as you grew up speaking it.
* Played with in ''[[Literature/TheMirrorOfHerDreams Mordant's Need]]'' - the Imagers all use a specific chant when summoning a manifestation from their magic mirrors, but it turns out that the chant is just a load of [[http://en.wikipedia.org/wiki/Barbarous_names meaningless syllables]]; however, the effort of remembering it puts your mind into the correct Zenlike state to allow the magic to work through you.
* A running gag in the ''Literature/RiversOfLondon'' series is that Peter finds learning Latin harder than actually learning the magic. The words simply a release of a pattern you hold in your mind. They're in Latin because that was the language UsefulNotes/IsaacNewton used for important works, and nobody's sure what would happen if they started messing around with it.
* In the ''Literature/MairelonTheMagician'' novels, at a basic level it doesn't matter what language a spell is cast in, but casting a spell in one's native tongue can cause the spell to be overpowered (Since you have to think about what you're saying when speaking in a second language, even if you're fluent, you also have to think how much power you're putting into the spell). As a result, spells written by the Greeks tended to be in Latin, and spells written by the Romans tended to be written in Greek, forcing modern magicians to learn both languages (As well as a bit of Hebrew) in order to use magic. It's also mentioned that with really complex spells, the exact meaning of a word does impact the effect, meaning it will matter what language the spell is cast in.
* ''Literature/TheLaundryFiles'' uses Enochian as the language of magic. It tends to work best when assembled not as spoken language, but as programming language.
* [[WitchSpecies Mages]] in ''Literature/{{Mithgar}}'' use a special language for their spellcasting. The spellcasting language of mainstream Mage society is represented as Latin, and the language used for the related-but-distinct rituals of the [[EvilSorcerer Black Mages]] is Ancient Greek, though WordOfGod explicitly states that the languages are not ''actually'' Latin or Greek, which were substitutions he used to give a modern English-speaker a feel for how the actual Mage languages sound and relate to each other.
* ''Literature/JourneyToChaos'': Some mages, like Dengel, pretended to know a special, magical, language to impress clients. It's actually gibberish. A mage of Dengel's standing didn't need to say anything at all.

* Magic in ''Series/BuffyTheVampireSlayer'' and ''Series/{{Angel}}'' tends to simply be a description of the spell in an ancient language (usually Latin). Apparently, in writing the scripts, writers would write a simple command, such as "open the door," and then mark it with "In Latin." However, Latin does not appear to be vital to spellcasting; a sufficiently powerful witch can skip it. See in particular the seventh season episode "Get It Done," in which Willow struggles for a while with a Latin incantation. She finally gives up and yells in English, "Screw it! Mighty Forces, I suck at Latin, okay? But that's not the issue! I'm the one in charge, and I'm telling you, ''open a portal, now''!"
*** Spoofed in one episode where Xander thinks that there's more to magic than just saying things in Latin, but accidentally sets a book on fire when he tries it himself.
-->Giles: Xander, don't speak Latin in front of the books.
* ''Series/{{Merlin}}'' seems to use Old English for this purpose. This is weird, given that Old English would have been the language of the Saxon invaders that King Arthur fought against. Chalk it up to TranslationConvention.
** However, probably due to the ''Series/BuffyTheVampireSlayer'' and ''Literature/HarryPotter'' examples above, quite a few fans have mistaken it for Latin and written their fanfiction accordingly. Despite the fact that the two languages don't sound at all similar.
** It was probably picked for the part because it's throaty and rhotic language, and thus sounds sufficiently mystical and alien to the modern Anglophone audience, whereas just about everybody knows approximately what Latin sounds like.
** The one exception is when he's in Dragonlord mode. It's indicated he uses the dragon language then. Which also appears to count for this trope.
** The dragon language is Homeric Greek. [[TheFairFolk The Sidhe]] use Old Irish.
* In ''Series/{{Bewitched}}'', the words "zolda, prancan, kopek, lum" are used to cast simple spells. When Maurice gives Darrin warlock powers, this is the first thing he teaches him, pointing out that you can just think the words, you don't have to say them out loud each time. Aunt Hagatha uses these words to float her teacup to herself, and Clara tries to, but mispronounces them slightly and her cup falls and breaks (Hagatha repairs it). Interestingly, when Samantha encourages Adam to float objects in one of the last shows, she does not teach him those words.
* In ''Series/{{Supernatural}}'', Enochian along with Latin and other ancient languages are used for incantations, exorcisms, and other rituals.

* ''TabletopGame/DungeonsAndDragons''
** Most spells have "[[MagicalIncantation Verbal Components]]" that must be uttered to cast spells. The exact form of these "components" is unspecified, and appears to change depending on the spell - indeed, several spells (most notably the [[BrownNote Power Word]] spells) are just their verbal components, so that the words themselves are magical. It's implied that the language of dragons, Draconic, plays a part.
** Words of Creation and Darkspeech are more literal languages of magic. Mortals require a special feat to be able to even say a few words of them, and they have distinct magical properties. Darkspeech, for example, can be used to reduce the hardness value of an object, while words of creation can be used to aid in item creation.
** There's also Truespeech: Speaking directly to the universe to tell it how things should be, to which it generally obliges, temporarily.
* Enochian (the language of angels devised by John Dee, Queen Elizabeth I's court magician) pops up in this context often, usually in roleplaying games with a focus on the divine (like ''In Nomine'' or ''Demon: the Fallen'').
* ''TabletopGame/MageTheAwakening'' has the High Speech. It's not ''necessary'' for magic, but it does give it a nice boost.
* ''TabletopGame/MageTheAscension'' has Enochian, but because [[ClapYourHandsIfYouBelieve magic works the way you believe it does]], Latin or other ancient languages will work. For that matter, so will the jargon of contract law. However, some seem to be better than others; one sourcebook includes a young mage worrying about an older mage whose house he's broken into using Latin, but the older mage tells him it's Sumerian that should concern him.
* ''TabletopGame/ArsMagica''. Latin, for the Order of Hermes, or other ancient languages for other magic wielders both in and out of the Order although they usually need the Gift if they want to play with power. Other languages used based on magical tradition include Gothic for House Bjornaer and Pictish for the Gruagachan. Classic Greek, as opposed to Romaic Greek, is used by members of the Order of Hermes in the Tribunal of Thebes.
* ''TabletopGame/{{Warhammer}} Fantasy Roleplay'' has the Lingua Praestantia, Daemonic, and Arcane Eltharin, all used exclusively for casting spells.
* ''TabletopGame/Warhammer40000'': While not technically magic ([[DependingOnTheWriter except when it is]]), members of the Adeptus Mechanicus can communicate to each other and to machines via a secret language called Binary, which even the Ordo Dialogos is incapable of translating.
** Well, it's considered magic by the rest of [[CargoCult the Imperium.]]
* Syntactic Magic from ''TabletopGame/{{GURPS}}: Thaumatology'' is an in depth version of this with several examples provided.
* ''TabletopGame/{{Exalted}}'' Sorcery is this. While anyone can use magic by performing thaumaturgical rituals, and any being with awakened Essence can channel their power in accordance with their nature, Sorcery is (according to second edition metaphysics) actually the "language" (if one can call it that) which the Primordials used to communicate concepts in order to create the world.
* ''TabletopGame/WorldOfSynnibarr''. Venderant Nalaberong is a language that was used by the Elder Gods to create the [[TheMultiverse Centiverse]]. Anyone who knows how to speak it can perform ultra powerful magical spells that are the strongest force in the Centiverse and can't be stopped by any other power.
* ''TabletopGame/{{Earthdawn}}'' supplement ''Dragons''. Dragonspeech is a form of telepathy that allows dragons to communicate with other creatures without speaking. The great dragon Vasdenjas says that dragonspeech can be used to communicate with the Universe itself and cause any pattern desired to be expressed in astral space, thus casting a spell.
* ''Powers and Perils''. As an optional rule, each type of spell has a supernatural language associated with it. Using a supernatural language to cast an associated spell increases the chance of success and the power of the spell if it succeeds.

* ''VideoGame/{{Bayonetta}}'' games have angels speaking Enochian, incantations written on various in-game props and magic users (Bayonetta, Jeanne, Balder) use spells in Enochian for summons.
* ''VideoGame/{{Everquest}}'' included the requirement to learn Dragon languages to master higher level spells.
* Inverted in ''VideoGame/WorldOfWarcraft'', where the warlock ability "Curse of Tongues" forces the target to speak in Demonic, thus making them take longer to cast spells.
** Confusingly, said curse also works on monsters of the Demon type...
* In ''VideoGame/FireEmblem 9'' and 10 spells are recored as simple pieces of ancient tongue (such as "The light of life! Shine a ray upon my path and...strike my enemy!" or "O light, gather. Open my path...") that are said as part of the casting process.
* In ''VideoGame/TreasureOfTheRudra'', the magic system is based on a LanguageOfMagic, and you can create custom spells by stringing the right syllables together.
** [[spoiler: The base syllables are: IG for Fire, AQU for Water, TOU for Electricity, TEO for Wind, SOA for Light, SERE for Dark, PRA for Earth, and NIHI for Void.]]
* In the ''[[VideoGame/ExaPico Ar tonelico]]'' series, all magic uses the Hymmnos language, which most of the time is sung rather then spoken. ItMakesSenseInContext with MagicMusic and MagicFromTechnology. Reyvateils literally communicate (verbally) with their local server to cast magic.
* In ''[[VideoGame/MagiciansQuestMysteriousTimes Enchanted Folk And the School of Wizardry/Magician's Quest Mysterious Times]]'', a magic language is used to cast spells, incantations, and communicate with various magical creatures (though it can also be used when interacting with other players).
* All ''VideoGame/{{Ultima}}'' games mention magical incantations of some kind (usually something Latin-sounding in the first games), but starting with the [[VideoGame/UltimaV fifth installment]] mages in the Ultima universe started using a standardized set of short words to form their incantations - for example, "In Lor" (literally "create light") illuminates your surroundings, and "An Nox" ("negate poison") cures poisoned characters.

* In ''Webcomic/ElfBlood'', most magic-casting characters use a symbolic language called Eldarin when reciting a spell. It's actually just a very simple direct substitution code. Some fans can read it fluently.
** Gipsy is not an actual spellcaster: She manipulates reality through what can only be summed up as 'true mathematics'. Although recently her 'spells' resemble C-like function calls more than mathematical formulae.
* In ''Webcomic/ElGoonishShive'', [[GratuitousJapanese Japanese]] fills this role for special techniques when practicing "''anime-style'' martial arts".
* In ''Webcomic/{{xkcd}}'', [[http://xkcd.com/353/ computer programming languages]] occasionally fill this role. A recent [[http://xkcd.com/824/ guest strip]] by Bill Amend of ''ComicStrip/FoxTrot'' fame demonstrates the power of UsefulNotes/{{Unix}}.
** Amend's strip is likely a ShoutOut to Munroe's own [[http://xkcd.com/149/ earlier strip]] on the same topic.
* Draconic in ''Webcomic/NahastLandsOfStrife'', though it doesn't seem to be necessary once you're skilled enough.
* In ''Webcomic/SluggyFreelance'' most magical spells are written using a bizarre alphabet straight out of Pete Abrams's imagination (as seen [[http://www.sluggy.com/daily.php?date=021017 here]]). How they're pronounced is anyone's guess.
* In ''Webcomic/{{Sorcery 101}}'', spells are cast by giving one's aura verbal instructions, generally using Latin. Not because there's something special about Latin, but because it's easier to learn magic when you don't actually know what you're saying.
* In ''Webcomic/WapsiSquare'', knowledge of the Lanthian language gives a person certain powers, and it can be used to command many Lantian artifacts.
* In ''Webcomic/BobAndGeorge'', [[http://www.bobandgeorge.com/archives/000506c the Author uses it to revive Dr. Light.]]
* Also the language of the Contract in ''Webcomic/ButImACatPerson'', and the focus of much of the research at Cohen's Being-research division.
* ''Webcomic/PennyBlackfeather'' has vaguely Asian/Persian writing that represents the language of magic. Ara speaks it for mundane purposes, though.
* In ''Webcomic/{{Unsounded}}'' the Khert is a BackgroundMagicField that understands the Old Tainish language, so a spell is any correctly worded set of instructions beginning with "Heed me, Great Khert." Spell Composers are always on the lookout for lost Old Tainish words that can be used in spellwork. Meanwhile, asking too many questions about why the Gods would design the infrastructure of reality to answer to the language of one specific, remote ancient tribe is a good way to get on the bad side of both the Gefendur ''and'' Ssaelit faiths.

* Common to the works of [[Website/ThingsOfInterest Sam Hughes]]:
** It's "science", not magic, but the fact remains that in ''Literature/FineStructure'', fluency in Eka gives a number of scientists RealityWarper powers.
** Similarly, in ''{{Literature/Ra}}'', [[https://qntm.org/what use of magic]] involves the speaking of magic words.
--> "Spells form a sort of API for requesting magical services. Spells are localised and for the most part take effect at the point in space where they are spoken. Simply speaking the words is not sufficient. The words serve as a mantra for the person speaking them, and it is the process of mentally jumping through various 'hoops' which actually causes the invocation to occur."

* Latin is used as a magical language in ''WesternAnimation/{{Gargoyles}}'', although the comics reveal that knowledge of Latin is not sufficient to cast spells.
** WordOfGod states that older languages are better suited to spellcasting -- while it's theoretically possible to cast a spell in English, it would take more than just a direct translation. In the episode "Golem", the spell to awaken the eponymous creature is in Ancient Hebrew.
*** Not just theoretically possible: The Magus managed it in "Avalon," although [[CastFromHitPoints it severely exhausted him.]] Of course, he was drawing power directly from Avalon itself, which was explicitly different from his normal magic.
* In ''WesternAnimation/TeenTitans'', Raven apparently uses one of these; normally all we hear is "Azarath, metrion, zinthos!" the mantra she uses to focus her will so she can safely use her inborn magical abilities, but on occasion (most notably in "The Prophecy") she'll go into an extended incantation in what sounds like the same language. The episode "Spellbound" also has Raven learn other spells with different incantations, but she refrains from using these after that episode because she can't control them.
** The RecursiveAdaptation ''ComicBook/TeenTitansGo!'' explains this a bit more in an issue where the team's powers are swapped around between them. Beast Boy ends up with Raven's powers, but when her usual incantation does nothing for him, she explains that it's because the words don't mean anything to him. Keep in mind, also, that the first word, Azarath, is the name of Raven's home dimension.
* In ''WesternAnimation/TheRealGhostbusters'', when an episode needs to bust out the truly powerful ancient spells, it's almost always Sumerian that the spells are written in. One episode comments that only three people in the entire world can read these kinds of spells, and Egon is one of those three.
** Subverted in an episode involving a ritual to summon the Old Ones.
--> Ree-kah, rah-kah, firecracker, sis-boom-bah, old ones, old ones, rah-rah-rah.
* In ''WesternAnimation/{{Ewoks}}'', most of Logray's spells contain an unknown language, as well as the one he performs with Teebo in order the tie the rocks chasing the Jindas in The Curse of the Jindas.
* The ''WesternAnimation/YoungJustice'' version of ComicBook/{{Zatanna}} uses backwards words to cast spells, much like her [[AddedAlliterativeAppeal classic comics counterpart]].

* Programming languages are essentially this trope made real.
--> A computational process is indeed much like a sorcerer's idea of a spirit. It cannot be seen or touched. It is not composed of matter at all. [...] The programs we use to conjure processes are like a sorcerer's spells. They are carefully composed from symbolic expressions in arcane and esoteric programming languages that prescribe the tasks we want our processes to perform.
-->-- [[http://mitpress.mit.edu/sicp/full-text/book/book-Z-H-9.html#%_chap_1 Structure and Interpretation of Computer Programs]], also known as the "Wizard Book" for the wizard on its cover.
* Also, you know, language in general. Think about it: language can summon people simply by knowing their name and observing proper ritual (Hey, John, please come over here), moving thoughts from your mind into the mind of another, mind controlling other people, creating illusions, and laying curses on your enemies.
* The Enochian language is use for many real life magic practitioners, particularly those of Thelemite, Rosicrucian and Hermetic traditions. The Enochian Magick is known as the Enochian System. The Church of Satan (no relationship with other Esoteric groups) uses [[DarkerAndEdgier a "satanized" version of Enochian]] developed by Anton [=LaVey=] in their magical rituals and ceremonies.
* Some Wiccans and other Neo-Pagan users of Magick prefer the use of ancient languages in their spells. Mostly languages related to their Pagan tradition like Gaelic for Celtic Wicca and Neo-Druidism, Latin for Nova Roma, Greek for Hellenistics, etc.
* Mantras are generally spoken in ancient dead languages like Sanskrit, and considering that a lot of Hindu and Buddhist mantras are meant to be something similar in concept to spells (as they are, in many cases, recited to attract good luck, blessings and health, repell enemies and evil spirits and even to cure the sick) could be consider a case of “language of magic”.
