Esperanto is a language constructed by L. L. Zamenhof in 1887 to help foster communication between countries. It was designed to be an easy-to-learn international language. The vast majority of the vocabulary is based on Latinate roots, as 1887 was still the age of colonialism, so for non-Europeans it can be harder to learn. Sadly, it didn't work as well as intended, thus spawning occasional mockery in modern media[[note]]and murderous rage on the part of those who oppose movements that attempt to bridge social gaps; [[UsefulNotes/NaziGermany the Nazis]] outlawed Esperanto and even sent some of its speakers to the camps.[[/note]]. Even then, it's still a thriving language within its own media, and there are a few people around the world who have grown up with Esperanto as a first language.[[note]]in addition to a natural language, obviously[[/note]] Some stories set in TheFuture use Esperanto as if it had become the main language. It's also occasionally used AsLongAsItSoundsForeign.

Esperanto is supposed to have the advantage of being more "logical" than national languages. It has only [[http://donh.best.vwh.net/Esperanto/rules.html 16 grammatical rules]], and it ([[http://www.xibalba.demon.co.uk/jbr/ranto/y.html almost]]) never deviates from those rules; also, each letter is pronounced one way and one way only. By contrast, English (unlike most national languages) is full of all kinds of weird spelling and grammar rules that make it much harder to learn than it should be. In addition, Esperanto words are much more easily creatable, using prefixes and suffixes around the root word to handily morph words in any way necessary, thus making sentences more concise and language more literal. (Opinions vary on the subject of how colorful language equivalents have solidly found their way into the language, morphable like any other word.) Written Esperanto presents a bit of a problem in the digital age, since 6 letters of the Esperanto alphabet -- ĉ ĝ ĥ ĵ ŝ and ŭ -- don't appear in the standard ASCII/ANSI character set; many authors choose to simply write the letter without the hat on it and put an x afterward, like so: cx, gx, hx, jx, sx, ux.[[note]]Eventually, even Esperanto's creator decided that these funny-looking letters were a bad idea, and unsuccessfully [[http://en.wikipedia.org/wiki/Reformed_Esperanto tried to get rid of them.]][[/note]]

Some informative sites about Esperanto (in English) are at [[http://en.wikipedia.org/wiki/Esperanto Wikipedia]], [[http://esperanto-usa.org/ Esperanto-USA]], and [[http://esperanto.net/info/index_en.html Esperanto.net]].

Despite its status as the best known artificial language, [[BrokenBase not everybody agrees]] with all parts of it, ([[http://www.xibalba.demon.co.uk/jbr/ranto/ as you can read here]]) and thus it has spawned other languages that have tried to correct perceived flaws. These projects are collectively known as [[http://en.wikipedia.org/wiki/Esperantido Esperantidoj]]; they include [[http://en.wikipedia.org/wiki/Ido Ido]], and [[http://en.wikipedia.org/wiki/Novial Novial]]. ([[http://en.wikipedia.org/wiki/Lojban Lojban]], although not directly related to Esperanto, is another example.) For one reason or other, these languages have been even less successful than Esperanto.

A few Wiki/TVTropes pages are available in Esperanto translations. To see the index, go [[Eo/VikiajTropoj here]].

For those who want to learn it, there is a [[http://pacujo.net/esperanto/course/ free E-mail course]], a virtually identical [[http://www.esperanto-usa.org/node/701 postal course]] (U.S. only, free except for postage costs), and [[http://lernu.net Lernu.net]]. More options [[http://www.esperanto.org/angle/kiel.html here]].

Incidentally, "Esperanto" is of course itself an Esperanto word (it means ‘one who hopes’), hence is pronounced "ess-pear-AHN-toe", not "ess-per-rant-o".

!!Examples:

[[foldercontrol]]

[[folder:Anime and Manga]]
* In ''Anime/{{RahXephon}}'' the TERRA organization's name is an [[FunWithAcronyms acronym]] for "Tereno Empireo Rapidmova Reakcii Armeo", which is ''supposed'' to be Esperanto for "Earth Empire Rapid Response Army". [[MyHovercraftIsFullOfEels Except "Tereno" means "terrain", "Empireo" is nonsense, as is "Rapidmova" and "Reakcii" means "to react".]] (They got "Armeo" right, though.) In proper Esperanto, the name should be "Rapid-responda Armeo de la Tera Imperio"...which, unfortunately, kills the acronym.
** Not to mention that in the first episode, Ayato and Mamoru greet each other with "Ĝis!" which is supposed to be used as a goodbye. Further amusement can be had from the fact that the dubbing team didn't seem to understand this and translated it as "Cheese!"
* ''{{Manga/ARIA}}'' has the scene in ''Origination'' when [[http://youtu.be/RXGUqYTbAwY Alice performs a canzone]], of which the first couple of verses are in Esperanto.
* In the ''Anime/NightOnTheGalacticRailroad'' anime, the signs are in Esperanto and Japanese. Esperanto appears also in various places throughout the film. This was most likely because Kenji Miyazawa, the writer of the original novel, was interested in the language.
* In ''Anime/SakasamaNoPatema'', [[http://www.dailymotion.com/video/x21652j_sakasama-no-patema-theme-song-sung-by-estelle-micheau-in-esperanto-english-subbed_music the song played during the end credits is in Esperanto, sung by the French singer Estelle Micheau]].
[[/folder]]

[[folder:Comic Books]]
* 25th century Creator/DCComics character ComicBook/BoosterGold speaks Esperanto as his first language.
* In Creator/GrantMorrison's ''ComicBook/{{Seaguy}}'', the universal language is Esperanto, but it's only revealed that everyone has been talking the language in the third, final, book of the first limited series. This is probably done to throw the reader off and make them see Seaguy's world as even more bizarre. It's mentioned again in the second book of the second limited series.
* The science fiction comic book ''[[TenJarojnPoste 10 Jarojn Poste]]'' is written almost entirely in Esperanto.
* The Gold Key ''Series/StarTrekTheOriginalSeries'' comics of TheSeventies for some reason explained away the "English" on new planets as the natives speaking Esperanto, rather than the UniversalTranslator from the TV show.
[[/folder]]

[[folder:Film]]
* ''Film/TheGreatDictator'': While the [[ANaziByAnyOtherName Ger...]][[CaptainErsatz Tomanians]] spoke AsLongAsItSoundsForeign GratuitousGerman, the population of the Ghetto had all their signs written in Esperanto.
** This is oddly fitting, since the language was invented by a Polish Jew.
* Esperanto is the second language of the unnamed city in the ''Film/{{Blade}}'' movies. ''Film/{{Incubus}}'' can be seen playing on a television at one point.
* The company Esperanto Filmoj is credited as producer of several films involving director Creator/AlfonsoCuaron, including Golden Globe winner and Oscar nominee ''Film/{{Gravity}}''.
* The anime movie ''Anime/NightOnTheGalacticRailroad'' uses Esperanto on all signs and inter-titles.
* The ''Film/StreetFighter'' movie has the fictional country of Shadaloo that speaks Esperanto.
* Two movies from TheSixties were filmed with dialogue entirely in Esperanto:
** The 1965 horror film ''Film/{{Incubus}}'' starred Creator/WilliamShatner and was produced by most of the first season ''[[Series/TheOuterLimits Outer Limits]]'' production team; it was filmed entirely in (poorly written and pronounced) Esperanto to sound more exotic.
** The other film was the French-made thriller ''Film/{{Angoroj}}''.
* In Murnau's ''TheLastLaugh'', all the signs are in Esperanto.
* Though all of the main characters of ''Film/{{Gattaca}}'' speak English, the announcements on the Gattaca Corporation's public address system are all in Esperanto. The Esperanto Society of North America is thanked in the credits. Which could mean that [[TranslationConvention the characters are actually speaking Esperanto]].
* ''Film/GerdaMalaperis'' ("Gerda Disappeared") is a film completely filmed in the language.
[[/folder]]

[[folder:Literature]]
* In HarryHarrison's ''TheStainlessSteelRat'' books, all the characters are understood to be speaking Esperanto. Esperanto is the universal second language in his ''{{Deathworld}}'' series. Harrison is a notable Esperanto buff himself, so it's quite understandable.
** Although in ''The Stainless Steel Rat for President'' he subverts this in having the inhabitants of a Spanish-speaking planet being completely unable to understand what Jim [=DiGriz=] is saying to his wife in Esperanto. And that despite so much of the Esperanto vocabulary coming from Latin, the root of Romance languages like Spanish.
* The ''{{Riverworld}}'' books, in which the language is deliberately spread by a post-resurrection religion so that they can proselytize more easily.
* Creator/DamonKnight's story "You're Another" had a dictator in the far future speaking with an Esperanto accent, with occasional words and phrases in Esperanto.
* In Isabel Allende's novel ''TheHouseOfTheSpirits'', the character Clara frequently mentions her belief that Esperanto is the ideal language and ought to be taught in schools.
* The MortalEngines series of four features a language called "[[IncrediblyLamePun Airsperanto]]," supposedly the language of those who fare the skies. It doesn't get too much prominence in the series, though.
* In ''Literature/TheYiddishPolicemensUnion'' by Creator/MichaelChabon, our hero lives in the Hotel Zamenhof. "When the hotel was built 50 years ago, all of its directional signs, labels, notices, and warnings were printed on brass plates in Esperanto."
* ''Polar Star'' (the sequel to ''Literature/GorkyPark''). An American sailor who learns Esperanto as a hobby mentions a meeting his group organised between two famous practitioners of the language. "It took us five minutes to realise they couldn't understand what each other was saying. One's asking for the wine, the other's telling her the time."
* ''Radio/TheShadow'' novel ''Malmordo'' has the title villain's name coming from bad Esperanto, and his international gang speaks the language. The Shadow, of course, is fluent in Esperanto (and UsefulNotes/{{Romani}}, the other non-English language important in the story.)
* Creator/IsaacAsimov wrote a short story, "Homo Sol", about humanity being inducted into a galactic [[TheFederation federation]]. The welcome message from their diplomats is delivered in Esperanto.
* In ''Literature/MeinKampf'', UsefulNotes/AdolfHitler claims that when The All-Powerful Jewish Conspiracy Of Doom takes over, a universal language will be instituted, and (jokingly) suggests it will be Esperanto.
* In Scott Meyer's ''[[Literature/{{Magic20}} Off to Be the Wizard]]'', all [[PowersArePrograms spells]] used by the "wizards" are activated with phrases in a bastardized version of Esperanto. Basically, they know the words but not the grammar, substituting English grammar instead. When asked by Martin why they don't use Latin, like most stories about magic, Phillip explains that a good number of locals (in 12th century England) understand at least some Latin. The most commonly-used spell is "flugi" ("fly"), which does exactly what you'd expect.
[[/folder]]

[[folder:Live Action TV]]
* ''Series/RedDwarf'' is a bilingual mining ship; signs are written in English and Esperanto (for instance, each floor is labeled with "Level" and "Nivelo"). Rimmer is occasionally seen working on his Esperanto. This was eventually dropped when Grant Naylor decided it was just silly. (The novel adaptation has everything in English, French and three dialects of Chinese).
** Rimmer also refers to Esperanto speakers as a distinct group, the "Esperantinos". (''Esperantino'' in Esperanto actually means "a woman who [[strike:hopes]] is hoping." The proper term in Esperanto would be ''Esperantisto''.)
*** Also plural isn't marked by an 's' but by a 'j'. So it would be the "Esperantistoj".
** You get the impression the dual-language thing is more political than practical-- as everybody in-universe speaks English all the time, and it's a plot-point that Rimmer doesn't even know esperanto. (Lister seems ok at it, though.)
*** Lister apparently learned it accidentally, being forced to ear Rimmer practicing.
** The catch all response to both of the above is Rimmer is an ''idiot,'' more so in the first and second series where the Esperanto signage appeared (it wasn't a feature of the set in later seasons).
* On ''{{Frasier}}'' the gang meets a [[CasanovaWannabe sleazy lounge singer]] who hits on Roz. She doesn't speak Spanish, but he is sure that she is "schooled in the international language." Frasier is unimpressed, quipping "Yes, Roz. Say something amusing in Esperanto!"
* A flashack episode of ''TheDrewCareyShow'' revealed that Lewis took Esperanto in high school, assuming it would actually be useful in the future.
* Referred to in ''[[QuiteInteresting QI]]'' in the "Future" episode, where Stephen Fry says, as an example phrase: "Mia kusenventurilo estas plena de angiloj." (MyHovercraftIsFullOfEels)
[[/folder]]

[[folder:Music]]
* The credits to Music/ElvisCostello's ''Blood and Chocolate'' album are in Esperanto, although some of the words are misspelled (it's "gitaro", not "guitaro").
* Legendary free jazz/underground rock label [[http://en.wikipedia.org/wiki/ESP-Disk ESP-Disk]], best known for signing Music/TheFugs, was originally intended to specialize in Esperanto music; its first release was a collection of folk songs in the language titled ''Ni Kantu En Esperanto'' (''Let's Sing in Esperanto'').
* From the Music/TheyMightBeGiants song ''Alienation's for the Rich'': "And the TV's in Esperanto/You know that that's a bitch".
* The opening track in Creator/MaayaSakamoto's album Kazeyomi, "Vento" ("Wind"), is in Esperanto.
* ''[=SYR3=]: Invito Al Ĉielo'' (''Invitation to the Sky'' or ''Invitation to Heaven'') by Music/SonicYouth has all its song titles, credits, and even the full title of the EP written in Esperanto.
[[/folder]]

[[folder:Video Games]]
* "Memoro de la Ŝtono" ("Memory of the Stone") from ''VideoGame/FinalFantasyXI'' is sung in Esperanto.
* The scenes before and after one mission in ''[[VideoGame/KatamariDamacy We Love Katamari]]'' have the King of All Cosmos working on his Esperanto.
** Only in the localization, as the original Japanese version had him practicing his English.
* In the Telltale ''VideoGame/SamAndMaxFreelancePolice'' games, an Esperanto bookstore is one of the businesses on their home block. Like most enterprises by the corner of Straight and narrow, it's ''closed''.
* The ingame ''[[VideoGame/TheElderScrollsIIIMorrowind Morrowind]]'' book ''[[http://www.uesp.net/wiki/Morrowind:Easter_Eggs#N.27Gasta.21_Kvata.21_Kvakis.21 N'Gasta! Kvata! Kvakis!]]'' is in Esperanto. (click the above link for a translation).
* In ''WanderingHamster'', the bubble-mage James is a member of the Esperanto League of Flanat (ELF). Bob the Hamster completely misunderstands both the acronym and the conversations that James has with the local guildmaster (he assumes that the two are talking mean about him). It's hilarious for the player, not so much for Bob.
* ''VideoGame/{{Touhou}}''. As shown in [[spoiler:Marisa B's]] Good Ending in ''Embodiment Of Scarlet Devil'', [[spoiler:some of Patchouli's books]] are written in Esperanto.
* ''BlazingDragons'' contains a throwaway gag by the caretaker for the Cave of Dillema where he offers to teach Flicker Esperanto.
[[/folder]]

[[folder:Webcomics]]
* In ''Webcomic/CwynhildsLoom'', Esperanto is the official language of UsefulNotes/{{Mars}} and is found on signs throughout the comic as well as on any type of computer output.
* The name of ''Webcomic/{{Homestuck}}'''s Kankri Vantas is derived from the plural form of the Esperanto word for "crayfish," in keeping with the crustacean theme of his descendant/ancestor, Karkat.
[[/folder]]

[[folder:Web Original]]
* ''TrintonChronicles'' have a few places where characters speak in Esperanto (actually IN Esperanto) and hold a tiny set of sentences in Esperanto.
* The Centaur language in ''[[TheIntercontinentalUnionOfDisgustingCharacters The Intercontinental Proliferation of Disgusting Characters]]'' is actually Esperanto (as described at the beginning of [[http://www.rogermwilcox.com/ADnD/IPDC7.html chapter 7]]).
[[/folder]]

[[folder:Western Animation]]
* ''WesternAnimation/TheJetsons'' took a long trip across the solar system to see a circus. There, the owner of a trained-flea act sold them his fleas [?]. George Jetson picked the fleas up and heard them making some noises. He knew they were trying to talk to him, but he couldn't understand what they were saying. George turned to his son, Elroy, and said, "You're the one taking Esperanto lessons? You talk to them!" Elroy was able to translate for the fleas!
* The ghost Wulf in ''WesternAnimation/DannyPhantom'' talks in broken Esperanto, and only Tucker can understand it at first. Danny and later Sam take Esperanto lessons.
* ''WesternAnimation/TinyToonAdventuresHowISpentMyVacation'' [[ParentalBonus astonishingly]] has a joke about Esperanto, which is found in the quotes page.
* Mocked by an alien in ''WesternAnimation/TheTick'': "Actually, Tick, I've taught myself to speak all your Earth languages. Except Esperanto. *chuckles* You could see ''that'' one was going nowhere."
* In the ''Batman-Superman: Apocalypse'' animated movie, the Kryptonian that Franchise/{{Superman}} and the newly-arrived {{Supergirl}} speak to each other is Esperanto.
[[/folder]]

[[folder:Real Life]]
* Baha'is were rather fond of Esperanto because they believe that a universal auxiliary (i.e. not replacement) language is necessary to facilitate world peace. This changed after they figured that it was [[MightyWhitey too Euro-centric]]. Nowadays, they're more fond of [[http://en.wikipedia.org/wiki/Lojban Lojban]], a derivative of [[http://en.wikipedia.org/wiki/Loglan Loglan]].
* And then there is [[http://en.wikipedia.org/wiki/Oomoto Oomoto]], in which Esperanto's creator is considered to be a god.
* The "Agressor Army" -- a [[http://www.youtube.com/watch?v=snCdEVIxXIs fictional enemy army]] which served in US Army war games between the late 1940s and the 1970s -- was expected to speak Esperanto.
