Need a scary and ominous sounding name? End it in "th".

For some reason this trope seems to be quite common in English-speaking fiction. Maybe it's because NamesToRunAwayFrom/NamesEndingInTh sound mysteriously ancient (due to this trope's prominence in some NamesToRunAwayFrom/AncientDeadLanguages: e.g., in ''Literature/TheBible'') or ominously [[NamesToRunAwayFrom/ForeignLanguageNames foreign]], maybe it's the sinister hissing sound itself... Whatever may be the case, NamesToRunAwayFrom/NamesEndingInTh is a sure-fire way to let your audience know: this person/place/artifact is to be feared.

It's usually used to denote:
* something so ancient it sends chills down your spine;
* something related to:
** demons;
** {{Eldritch Abomination}}s;
** gods (most often those who aren't so different from demons or {{Eldritch Abomination}}s);
** dark and forbidden magic.
Sometimes a partial aversion takes place, and we get something from the aforementioned list (e.g., something ancient) that ''isn't'' terrifying or evil.

[[folder:Anime and Manga]]
* ''Manga/{{Bokurano}}'': The kids who pilot it didn't intend to give it scary name, but considering [[CosmicHorrorStory the context of the story]], [[HumongousMecha Zearth]] fits this trope to a T [[spoiler:especially if you're not from the main characters' universe]].

* Creator/DCComics:
** [[Characters/NewGods Bernadeth]] of the ''ComicBook/NewGods''. [[StevenUlyssesPerhero Guess what she does.]]
* Creator/MarvelComics:
** ''ComicBook/TheMightyThor'':
*** Malekith the Accursed, a supervillain, ruler of the Svartalfar (Dark Elves).
** ''Comicbook/DoctorStrange'' comics have a lot of those:
*** Shuma-Gorath, an EldritchAbomination and a recurring foe of the good doctor. The name "Shuma-Gorath" actually appeared first in a Creator/RobertEHoward story, where it was mentioned by a magician called Rotath.
*** Yandroth, a powerful malevolent alien scientist-wizard.
*** Lilith (see [[foldercontrol]]

[[folder: Mythology / Religion ]]
) makes an appearance as a powerful demoness. There's also another character called Lilith in Creator/MarvelComics; she's the daughter of {{Dracula}}.
*** Sligguth, a demon.
*** Dagoth, a demon.
*** Hoggoth, as in "[[CatchPhrase by the hoary hosts of]]"
** ''ComicBook/XMen''
*** [[Characters/XMenVillains Sabretooth]].
** ''ComicBook/ConanTheBarbarian'' comics:
*** Kulan Gath, a powerful evil magician. He also has an apprentice called Razal Gulath.

* The ''StarWars'' series:
** The Sith.
** Darth, a title used by many prominent Sith.
** Hoth, the forbidding ice planet where the rebels were temporarily based.
* Dagoth the Dreaming God from ''Film/ConanTheDestroyer''.
** The wizard Thoth-Amon.
* ''Film/{{Labyrinth}}''
** Jareth
* Malekith the Accursed from ''Film/ThorTheDarkWorld.''
* ''Film/SchindlersList'' has real-life [[ThoseWackyNazis Nazi]] war criminal Amon Göth/Goeth as a villain.
* Hyman Roth, the BigBad of ''Film/TheGodfather Part II''.[[/folder]]

* The TropeCodifier here may be Creator/HPLovecraft, who liked this trope '''a lot''':
** Asenath Waite, from "Literature/TheThingOnTheDoorstep". She's perhaps the only human in Lovecraft's works who got a Name Ending In Th... and that says a lot.
** Azathoth, the Blind Idiot God. A gigantic EldritchAbomination, that once was a demiurge, but nowadays just dwells somewhere in deep space listening to music.
** Innsmouth, the titular place from "Literature/TheShadowOverInnsmouth". Even though the name is English in origin, the "th" at the end hints that something is [[IncrediblyLamePun fishy]] about this place...
** Kadath, from ''Literature/TheDreamQuestOfUnknownKadath''. It's the last dwelling of the gods, inaccessible to mere mortals.
** Sarnath, from "The Doom That Came to Sarnath". A forgotten ancient city, that, [[ExactlyWhatItSaysOnTheTin well]]...
** Shoggoth, a type of creatures looking like a giant formless puddle of black goo with a lot of eyes, featured in ''Literature/AtTheMountainsOfMadness''.
** Shub-Niggurath, the Black Goat with a Thousand Young. One of the most well-known Great Old Ones.
** Yith. Home planet of The Great Race of Yith, a powerful alien race capable of swapping minds with creatures of another eras, featured in "Literature/TheShadowOutOfTime".
** Yog-Sothoth, aka the Key and the Gate, and The All-in-One and the One-in-All. A powerful cosmic EldritchAbomination who looks like "a congeries of iridescent globes" that is essentially an embodiment of... well.. everything. As in, all of space and time and the entire multiverse.
*** Yog-Sothoth and Azathoth even have an additional "th" in the middle!
*** Other names with a "th" in the middle (but not at the end) include Ithaqua, Nyarlathotep.... and of course, [[Literature/TheCallOfCthulhu Cthulhu]].
** Yuggoth, the dark planet on the edge of the solar system. (The narrator of "Literature/TheWhispererInDarkness" identified it with the then-newly-discovered Pluto, but [[ScienceMarchesOn as we now know, Pluto is not a planet]] .) But it's more terrifying than it sounds, since in Lovecraft's works Yuggoth is inhabited by all kinds of {{Eldritch Abomination}}s.
* More NamesToRunAwayFrom/NamesEndingInTh appeared in the works of other CthulhuMythos authors:
** Abhoth
** Daoloth
** Ghroth
** Nug-Soth
** Planet names include Abbith, Haddath, Kynarth, Xoth, Yaddith and Zaoth.
** The family tree of Tsathoggua, an Old One, includes such names as Cxaxukluth and Ghisguth. Also, Tsathoggua himself lives on a mountain called Voormithadreth.
** The creator of the term Franchise/CthulhuMythos, Lovecraft's associate and horror author Creator/AugustDerleth, even had a [[NamesToRunAwayFrom/NamesEndingInTh Name Ending In Th]] himself!
* Averted in Franchise/TolkiensLegendarium: words and names ending in 'th' are quite common in Creator/JRRTolkien's {{conlang}}s, and there are both villains (e.g., Morgoth -- makes sense, since "goth" means "foe") and heroes (e.g., Elbereth) whose names end in ''-th''. Played straight, though, with the Ringwraiths.
* ''Literature/{{Discworld}}'':
** Yob Sodoth (a parody of Yog Sothoth), mentioned in ''Pyramids''.
** Bel-Shamharoth, the Sender of Eight, an EldritchAbomination mentioned in some of the early Rincewind books, and giving passing mention to his cultists "The Young Men's Reformed Cultists Of Bel-Shamharoth Association", a parody of the YMCA, in some of the Death books.
* ''Franchise/StarWarsLegends'', in addition to the ''Franchise/StarWars'' terms mentioned in the {{Film}} section, also gives us the EldritchAbomination Abeloth.
* ''Literature/DragonridersOfPern'':
** A partial aversion. [[ThemeNaming All dragon names end in "th"]]. While their fearsome appearance has been used to intimidate on at least one occasion, Pernese dragons are depicted as generally friendly and would never knowingly harm a human. (Except at hatching, and that's usually due to unfamiliarity on the part of at least one of the involved parties.)
* ''Literature/SwordOfTruth'':
** Mord-Sith, an all-female order of inhumanly sadistic torturers. (Gaelic for Death Faerie, slightly less terrifying to those who don't know anything about Gaelic or Celtic mythology, ten times as horrifying to those who do.)
* An ancient ogre named Mulgarath serves as the BigBad of ''Literature/TheSpiderwickChronicles.''
* Morgarath, BigBad of the first two ''Literature/RangersApprentice'' books.
* Mordeth of ''Literature/TheWheelOfTime'' series, and yes, unless you want him to possess your body and subject to the world to the same corruption as the city he's bound to, you probably ''should'' run.
* The Astaroth of the ''Literature/FaeriesOfDreamdark'' series actually has two NamesToRunAwayFromReallyFast; he's also known as [[NamesToRunAwayFrom/{{Colors}} the Blackbringer]].
* The {{Backstory}} in ''Literature/CharlieAndTheChocolateFactory'' {{Backstory}} has several {{Corrupt Corporate Executive}}s sending spies into the Wonka factory to steal his recipes: named Prodnose, Ficklegruber, and '''Slugworth'''. It's probably telling that Slugworth becomes an AscendedExtra in the first movie adaptation of the novel, ''Film/WillyWonkaAndTheChocolateFactory'', with a subplot involving him trying to exploit the Golden Ticket tour by bribing the five finders to steal a prototype Everlasting Gobstopper for him.

[[folder:Live-Action TV]]
* ''Series/DoctorWho'':
** Chancellor Goth, from [[Recap/DoctorWhoS14E3TheDeadlyAssassin "The Deadly Assassin"]].

** The Gelth, from [[Recap/DoctorWhoS27E3TheUnquietDead "The Unquiet Dead"]].
* ''Series/{{Supernatural}}'':
** Lilith, BigBad of Seasons 3 and 4.

[[folder:Mythology and Religion]]
* Myth/CelticMythology:
** Wraith, a type of Scottish ghost.
** "Sìth"[[note]]pronounced SHEE-thuh[[/note]] is a UsefulNotes/{{Scot|land}}tish Gaelic term (the UsefulNotes/{{Ir|eland}}ish Gaelic equivalent being "sídhe"[[note]]also pronounced SHEE-thuh[[/note]] or "sí"[[note]]pronounced SHEE[[/note]]) associated with a variety of spirits that are often quite dangerous. The term originally referred to the mounds where the spirits lived, with "daoine sìth"[[note]]pronounced DEE-nuh SHEE-thuh[[/note]] (Scottish) and "daoine sídhe"[[note]]also pronounced DEE-nuh SHEE-thuh[[/note]]/"aes sídhe"[[note]]pronounced ACE SHEE-thuh[[/note]]/"aos sí"[[note]]pronounced ACE SHEE[[/note]] (Irish) meaning "people of the mounds" -- although nowadays "sìth"/"sídhe"/"sí" often refer to the spirits themselves. Also note that in accordance with (appropriately enough) TheScottishTrope, Gaelic traditions often use [[IHaveManyNames numerous other names]] like "the Good Neighbours" and "TheFairFolk" to avoid [[SpeakOfTheDevil drawing the spirits' attention]].
* Literature/TheBible and related sources have a lot of this; the reason for this is that many Hebrew words end in the letter ''[[ tav]]'', as it is a marker for feminine gender (both in the singular and in the plural form ''-ot''). The ''-ot'' version is particularly common, thanks to the [[ pluralis excellentiae]], i.e. "calling the singular thing plural to emphasize how awesome/terrible (classical sense) it is".[[note]]Examples: ''Behemot''="Wild Beasts"="One wild beast"; ''Elohim''="gods"={{God}} Almighty Himself, trying not to piss him off by saying His name.[[/note]] In Biblical Hebrew, final tav was pronounced ''-th'', which morphed to ''-s'' in Ashkenazi and ''-t'' in many Sephardi/Mizrahi dialects (which eventually became the model for Standard Hebrew).
** Demon names, which include Astaroth, Balberith, Berith, Bileth, Lilith and Obizoth.
** Goliath, a Philistine champion of Gath and all-around badass "whose height was six cubits and a span". During a war he [[ThrowingDownTheGauntlet issued a challenge]] to his enemies: King Saul and the armies of Israel, and he instilled fear in all of them.
** Behemoth, a monstrous creature mentioned in the book of Job.
** The Qliphoth, evil beings from Jewish teachings (e.g. the Kabbalah). They include the Gamchicoth (Devourers) and Nehemoth (Whisperers).
* Alchemical and occult sources:
** Azoth, a mysterious substance sought by some alchemists. Creator/AleisterCrowley mentioned it in some of his works.
* Myth/EgyptianMythology:
** Seth (or Set), an evil chaos god and the murderer of Osiris.
** Thoth, the god of knowledge and the moon. His name consists of nothing but 2 "th"s separated by a vowel, and his head was that of an Ibis (which most people won't recognize and is only one letter away from Iblis).
** Neith, a goddess of warfare, hunting, and [[ArsonMurderAndJaywalking weaving]] (in fact, her name means "weaver"). She eventually also came to be considered a goddess of creation.

** Or perhaps you should ask the mammoths about said ancestors--they were probably more scared of humans than the other way around, given that we snacked on them to the point of extinction.
