-> ''"[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''', ''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:

[[foldercontrol]]

[[folder:{{Comics}}]]
* 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."
[[/folder]]

[[folder:{{Literature}}]]
* 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 ''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/EarthseaTrilogy'', 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. 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 {{Nasuverse}}, the [[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 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 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.
[[/folder]]

[[folder:VideoGames]]
* In [[VideoGame/TheElderScrollsVSkyrim Skyrim]], the language used by dragons works this way. A loading screen factoid helpfully explains that when two dragons use their breath weapons against each other, they're actually having an intense philosophical debate.
** Extending from this are the Words of Power, which you learn and string together to create magical "Shouts". [[spoiler:It is later revealed that every true dragon's name is a three word Shout]]. This includes the Dragonborn, or "Dov Ah Kiin"--"Dragon Hunter Born/Child".
[[/folder]]

[[folder:WebOriginal]]
* The language of the Sidhe seems to be this in the 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 ''TrintonChronicles'' is that there are true and half-[[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.

[[/folder]]

!!Other examples:

[[folder:{{Anime}} and {{Manga}}]]
* In ''[[SuzumiyaHaruhi The Melancholy Of Haruhi Suzumiya]]'', Yuki casts spells ''by chanting SQL queries sped up and played backwards.''
* In ''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.
[[/folder]]

[[folder:{{Comics}}]]
* The [[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''.
[[/folder]]

[[folder:{{Literature}}]]
* Generally speaking, one does not need a special language to work magic in 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 [[AWizardDidIt 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.
*** At least one fan theory is that spells can be said in any language, but the important things are the wand and the mind to focus the magic. Using foreign words makes it easier to focus on a specific spell, so that saying stuff in your own language doesn't accidentally create disaster (ie. "Could you give me that pot?" -All pots in room zoom towards you-)
* In ''TheElenium'' and ''The Tamuli'' trilogies by 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.
** Another reason why foreign or nonsense words are used: you don't want to create a raging inferno by just saying "fire."
*** Which triggers a bit of 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]]."
* 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 JohnCWright's ''Literature/ChroniclesOfChaos'' this is one technique of magic.
* Magic in the ''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. (What happens to sorcerers who screw this up -- whether nothing happens or something exceedingly bad and unintended happens -- isn't specified.)
** It can probably be inferred that nothing happens. If something very bad happened from flubbing a spell, it's unlikely any sorcerers would survive their apprenticeships.
* 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.
* ''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 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 {{Dragonlance}} series has wizards who, like standard 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 ''{{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 ''[[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 IsaacNewton used for important works, and nobody's sure what would happen if they started messing around with it.
[[/folder]]

[[folder:LiveActionTV]]
* 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.
[[/folder]]

[[folder:TabletopGames]]
* ''DungeonsAndDragons''
** Most spells have "[[MagicalIncantation Verbal Components]]" that most 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'' had 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/Warhammer40K'': 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.
* 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.

[[folder:VideoGames]]
* ''{{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 ''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 ''TreasureOfTheRudras'', 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 ''ArTonelico'' 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 [[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 ''Franchise/{{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.
* The Thu'um in ''VideoGame/TheElderScrollsVSkyrim''. It is the language of the godlike Dragons, which they use to bend reality at a whim. Mortals can learn the Thu'um as well, though they need to devote their entire lives to mastering it and most can never speak normally when they reach that point. The Dragonborn doesn't have this problem since he/she is technically a Dragon too. Interestingly, mortals were able to invent a Shout that embodies concepts that are wholly alien to Dragons [[spoiler:"Mortal, Finite, Temporary"]]. Yes, mortals invented words in the Dragons' language that the Dragons themselves don't know.
** The Dragons likely knew those words but cannot truly understand the meaning of them, and are therefore incapable of using them in a Shout. It's similar to a human trying to wholly understand the concepts of [[spoiler: Immortality, Infinity, and Permanency.]]
*** It should also be noted that in previous Elder Scrolls games the spell to keep other magic users from casting is known as "Silence" which implies that normal magic also has a verbal componet
[[/folder]]

[[folder:{{Webcomics}}]]
* In ''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 ''{{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 ''{{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 ''WapsiSquare'', knowledge of the Lanthian language gives a person certain powers, and it can be used to command many Lantian artifacts.
* In ''BobAndGeorge'', [[http://www.bobandgeorge.com/archives/000506c the Author uses it to revive Dr. Light.]]

* It's "science", not magic, but the fact remains that in ''Literature/FineStructure'', fluency in Eka gives a number of scientists RealityWarper powers.

* 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 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 ''YoungJustice'' version of {{Zatanna}} uses backwards words to cast spells, much like her [[AddedAlliterativeAppeal classic comics counterpart]].

* Various dead languages are used for ritual purposes by new religious movements and practitioners of "magick", such as Latin, Hebrew, Sanskrit etc. Sometimes {{ConLang}}s are used, ranging from unimaginative letter substitutions to sophisticated creations like the [[http://en.wikipedia.org/wiki/Voynich_manuscript Voynich manuscript]] (which has never been deciphered).
** A notable example being [[http://en.wikipedia.org/wiki/Enochian Enochian]], the so-called angelic language invented by John Dee.
* Programming languages are essentially this trope made real.
