->''"Ye knowe eek that in forme of speche is chaunge\\
With-inne a thousand yeer, and wordes tho\\
That hadden prys, now wonder nyce and straunge\\
Us thinketh hem, and yet thei spake hem so."''
-->-- '''Creator/GeoffreyChaucer''', 600 or so years ago [[labelnote:Translation]]"You know that it is in the nature of language to change within a thousand years, and words which then held high regard, now seem to us absurd and unfamiliar, but thus they spoke."[[/labelnote]]

All languages are always changing, all the time, so long as someone is alive to speak them. This is the basic idea behind [[http://en.wikipedia.org/wiki/Historical_linguistics an entire discipline of linguistics]]. It means that a thousand years' difference (for example, between [[HistoryOfEnglish Old English and modern English]]) can make two versions of the same language completely unintelligible; another thousand (as with the 2,000 years dividing Latin and modern French) and you might not even realize they're related.

In real life, [[FishOutOfTemporalWater a character traveling into the distant future]] would literally have to learn [[http://jbr.me.uk/futurese.html a completely new language]]: even if people are still using spoken language rather than, say, ElectronicTelepathy and even if they are speaking what they call "English", there's a fairly high probability that it won't be similar enough to the character's English to allow intelligibility.[[note]] While all languages change, they do so at different rates: English is highly mutable while, for example, Icelandic is quite stable -- and even its pronunciation is quite divergent from Old Norse. It has been stipulated that this is directly relevant to the magnitude of societal and cultural change, and that a global communication network that persists for many centuries would prevent English from changing much, for reasons of compatibility with older but commonly available and accessed historical data.[[/note]] In fiction, however, linguistic drift is almost universally ignored. For writers, it's a lot of trouble to translate into an ancient or imaginary language, and audiences often prefer to watch a show in their native language. Therefore, people hailing from vastly different time periods will almost always speak the language of the audience, and rarely with so much as JustAStupidAccent (though characters from TheMiddleAges or thereabouts typically speak YeOldeButcheredeEnglishe).

In many future settings, the writers will try to balance this out by throwing in [[FutureSlang a couple of new slang words]] or having a handful of words [[HaveAGayOldTime gain]] or [[GetTheeToANunnery lose]] an embarrassing connotation over the years. Others will try to attribute this trope to the advent of recording technology. This may or may not turn out to be the case: after all, we are discussing tropes and memes on a wiki hosted on the web. Someone from the year 2000 wouldn't understand some of that sentence, while someone from 1990 would understand almost ''none'' of it (hell, a good number of people ''today'' still wouldn't understand it). On the other hand, while Creator/WilliamShakespeare would be unable to understand the sentence "His car's on the blink--the distributor is busted", the very concept of "car" being alien to him, it's entirely possible to read his works with a dictionary at most for troublesome words, and were we to pop into 1600 and chat with him about the weather, we'd have trouble with each other's accents and a few changed grammatical features, but no worse than, say, an American Southerner on first meeting a Yorkshireman.

In some cases, a work will be set in a distant time period, but the characters don't encounter any time travelers, read modern books, or watch modern movies. Settings like these are actually invoking TranslationConvention.

The absence of LanguageDrift. Compare with AliensSpeakingEnglish.


[[folder: Anime and Manga ]]
* In ''VisualNovel/FateStayNight'', Servants are summoned from the distant past and seem to have no problem conversing fluently in modern (even accentless, in the anime) Japanese. No matter where a Servant comes from, and no matter when they were alive, once they are summoned, they are given basic knowledge of the world at the time of their summoning, including a familiarity with the average level of technology and [[TranslatorMicrobes a decent grasp of any languages they would be likely to use]].
* ''Anime/InuYasha''. Kagome falls into around the year 1550 and has no trouble understanding [[http://en.wikipedia.com/wiki/Late_Middle_Japanese Late Middle Japanese]]. Inuyasha has managed to come to the present without any trouble either.
** The English translation has the elderly Kaede use the archaic thou and thy, hinting at the language changes. For some reason though, the characters who are even older than Kaede (including her sister Kikyo who gets revived in undead form, and most of the villains of the story) ''don't'' speak in a similarly archaic manner. 1550 is only five decades away from the start of Modern Japanese, so it's understandable that Kagome wouldn't have too much trouble.
* There is an "Outer World" in ''Anime/{{Slayers}}'' that has been blocked off by [[AWizardDidIt a magical barrier]] courtesy of the [[AlwaysChaoticEvil Monster Race]] for at little over a millennium, hence two different cultures: the "Inner World" (i.e the main setting of the series) thrives on magic, and WordOfGod put out that everyone in it speaks the same language. The "Outer World" has little access to magic and thrives on technology instead, and has peoples in various types of environments, including a scant amount of primitive tribes. The third season of the anime has the main party go to the Outer World, but unless one member of the group has a translator on them, it would be unlikely that the Outer Worlders would speak the same language (whatever the heck it is) as they do. This problem doesn't arise in the novels because Lina and Gourry stay in the Inner World for the entire time.
* ''Anime/TurnAGundam'', despite taking place thousands of years in the distant future, still has Earth-bound humans (and possibly the Moonrace) using modern English. Though this ''might'' be handwaved by the fact that much of the series takes place in what used to be United States.
* Apparently, contemporary English has become the ''lingua franca'' of the [[UnitedSpaceOfAmerica Free Planets Alliance]] in ''Anime/LegendOfGalacticHeroes.''
* Played straight in the anime ''LightNovel/CrestOfTheStars'' where Martine speaks English while the Abh speak [[ConLang Baronh]] ([[TranslationConvention represented by Japanese]] sprinkled with Baronh terms).
** The novels zigzag on the issue. Martinese is descended from English but when trying to communicate with a young Jinto he can't understand it. It's unclear if these means that English is till being used somewhere or if at least some people know it but its no longer a living language like Latin in the modern world

* {{Lampshade|Hanging}}d in ''[[Franchise/{{Batman}} The Return Of Bruce Wayne #2]]'': a man in Puritan times says to time-shifted Bruce Wayne: "All agree thy speech is ''stranger'' even than the Dutchman's here. As if the ''King's English'' were not thy ''native'' tongue." Which is understandable, since they all speak [[YeOldeButcheredeEnglishe (an approximation of)]] 17th century English, while Wayne speaks modern English.
* A ''ComicBook/NewMutants'' story involving time-travel brought them to the middle ages where Wolfsbane (Rahne Sinclair, aged 14 or 15) was able to converse fluently with Robert the Bruce just by virtue of coming from Scotland while her teammates weren't. There was no indication that Rahne had learned Middle English or indeed Scots Gaelic (should Robert have even spoken the latter; it had already become a minority language by the Bruce's era). Or Modern Lowland Scots, which is actually closer to Middle English than to modern English, but Lowland Scots is a nearly dead language, even less likely to Rahne to know anything about. Especially since she's a Highland Scot.
* In [[ComicBook/BlakeAndMortimer ''The Machiavellian Trap'']], when Mortimer travels to the future, at first he is only able to hold a conversation with a scholar who recognizes his language as "ancient English"... yet a few pages ''before'' he'd been casually interacting with people in fifteenth-century ''France'' without any language problems.


[[folder:Films -- Animated]]
* ''WesternAnimation/WallE''. Of course, there's a good reason why humans haven't really changed language a lot in a few centuries.

[[folder:Films -- Live-Action]]
* ''Film/PlanetOfTheApes1968''. It's 2,000 years in the future, and the apes are still speaking perfect English. Although they don't call it that...Cornelius just says it was the language taught to him by his father and his father before him.
** Justified by apes' CreativeSterility: the technology hasn't changed either.
* {{Lampshade|Hanging}}d in ''Film/TeenageMutantNinjaTurtlesIII'', when the Turtles in Feudal Japan find that ''everyone'' they talk to knows English, which had been introduced to Japan only a few years earlier.
* The film version of ''Film/{{Timeline}}'' has this, with medieval French and English soldiers speaking the early 21st century version of their languages perfectly so that the English troops have no problems communicating with the modern-day heroes. This was handwaved by TranslatorMicrobes in the book, which made a specific plot point of the fact that the medieval people spoke contemporary dialects of those languages (as well as Occitan and Latin), and having the time travellers struggle to be understood by them (because they naturally lacked the hidden earpiece translators the time travellers wore).
* In ''Film/TheTimeMachine1960'', the Eloi speak perfect English over 800,000 years in the future. Explained with the Morlock leader through the use of PsychicPowers.
* In ''Film/TheTimeMachine2002'', English is NOT the main language. It is a dead language taught to some people akin to Latin. Teachers and well educated people are the only ones who know it.
* The English language in ''Film/{{Idiocracy}}'' has degenerated into a combination of Ebonics, Redneck, Valley Girl and Hispanic gang banger by the 25th century. People have difficulty understanding the protagonist from early on.
* In ''Film/LesVisiteurs'', Godefroy and Jacquouille have very few difficulties with modern French, despite being from an era where [[https://en.wikipedia.org/wiki/Old_French Old French]] would be the standard. There are a couple of DoubleEntendre gags related to HaveAGayOldTime, but even for those, the archaic forms are still proper, if seldom-used, modern French. The pronunciation, of course, is pure modern French across the board.

* Probably present in [[Creator/LoisMcMasterBujold Bujold's]] Literature/VorkosiganSaga, which is at a remove from the present in a comparable way that we are from Ancient Rome, but characters read [[Creator/WilliamShakespeare Shakespeare]] and use YiddishAsASecondLanguage.
** Barrayar has been isolated from Galactic culture for centuries and reverted to medieval level[[note]]armored knights, later muzzle-loaded guns; lack of literacy; superstitions[[/note]]. It's specifically mentioned that only 4 languages survived: English, Russian, French and Greek. All four differ significantly from their galactic versions, yet remain intercomprehensible with them.
** Cordelia at one point finds a book of poetry written in English but using the Cyrillic alphabet.
** Possibly the difference is more in pronunciation than anything else. At another point Elli finds it unnerving when Miles switches between guttural Barrayaran accent and "musical" Betan.
* Creator/ArthurCClarke:
** In ''3001'', sound recording technology is said to have stabilized all languages. As a result, they have changed about as much as is appropriate for two or three hundred years, instead of the thousand that have actually elapsed.
*** Although there are also many new words and terms in the language (which is referred to as Anglish), mostly from scientific and technological advancement. The protagonist (from a thousand years earlier) also has some difficulty getting the voice-activated technology to understand his accent.
*** It is implied that there may be bigger differences in the language, but the people interacting with the main protagonist have had the early 21st century English uploaded into their brains for his comfort. They make the occasional unsettling mistake, like saying "KO" instead of "OK".
** Clarke relied on the same justification in ''Literature/TheSongsOfDistantEarth''.
* Creator/LSpragueDeCamp wrote a surprisingly funny, informative, and accurate essay called "Language for Time Travelers", where the FramingDevice for the information is the travails of a {{time travel}}er having to deal with [[ShownTheirWork vowel shifts, abbreviation, and slang]] in the future. It's worth tracking down, and you may learn something.
* Used to a ludicrous extent in ''Literature/TheFadedSun'' trilogy, where the high tongue (formal language) of the Mri is show to have been completely stable between two isolated groups of Mri for approximately a million years.
* Played straight in Creator/LordDunsany's short story ''The Avenger of Perdondaris'' where in the far future a shepherd's offer of hospitality is 'Everkike' or 'Av er kike,' badly decayed Cockney for 'Have a cake.'
* Beautiful subversion in Creator/CSLewis' ''Literature/ThatHideousStrength'': The bad guys have gone to great lengths to awaken the sleeping wizard Merlin, long buried in his tomb beneath Glastonbury Hill, and extract from him his knowledge of ancient magics. The project leader interrogates Merlin for hours in impeccable medieval Latin, only to get no response. They then try communicating in Gaelic, Welsh, Old English, and start running through the list of ''any'' ancient languages that Merlin might have spoken. Merlin continues to fail to respond, leading them to the conclusion that he's purposely stonewalling them. While they go off to confer as to how to negotiate with him, our protagonist sneaks in and randomly greets Merlin in normal modern English, and, of course, Merlin begins a friendly chat with him. It transpires that the ''real'' Merlin actually woke up and fled the scene hours ago, and the man they've got is just a random homeless guy who wandered into the site and thinks everyone around him is insane.
* Played completely straight in Creator/AnneMcCaffrey's ''Literature/DragonridersOfPern''. Despite taking place 2,500 years after Pern was colonized, rhymes and puns still work in English, the entire planet speaks one homogenous language and ancient documents from the original colonization of the planet are completely readable by the modern characters. Additionally, a trip back in time reveals no linguistic difficulties whatsoever.
** However, it is noted in later books that both the dolphins and AIVAS have trouble understanding/being understood.
*** Also, Robinton is distressed to discover the language has altered at all, saying that it's the job of the Harpers to make sure the language doesn't change. Oddly, he and other characters assume that the dolphin's grasp of the language is closer to the old form even before checking with AIVAS
* Played straight in Creator/{{Ken MacLeod}}'s ''Learning The World''. The book takes place 14,000 years in the future, by which time it seems virtually certain that English will have changed drastically, in the unlikely event that anything that could be called English still exists at all. Despite this, an important plot point hinges on the fact that the word "bug" could mean either "insect" or "spying device".
** Many other languages do use words that mean "small creepy-crawly animal, possibly parasitic" in idioms for concepts like "curse", "nuisance", and "tag-along", so it's entirely possible whatever they speak has a ConvenientlyPreciseTranslation.
* Creator/JRRTolkien was a professor of linguistics and fully aware how unrealistic this trope is, but he used it anyway with the (roughly) 500-year-old Gollum in ''Literature/TheLordOfTheRings''. Actually, the 500 year age might be dealing with a {{retcon}} attempt to avert it. The ''appendices'' are the ones making Gollum 500. In fact, they ''specifically'' mention events which make it possible for him to be 500 - like the Hobbits temporarily returning to Anduin around that time while Sauron was banished, but the book itself seems to imply he's closer to 2000 - and the Silmarillion states explicitly he's a thousand at least (the Ring was stated to be found while Gondor still had kings).
** It is also explicitly mentioned at some point that the text of the Rings books have been *intentionally* rendered as Modern English, even though the different ages and regions would have had different dialects and (to an extent) vocabulary. [[TranslationConvention Apparently, this is done to make it easier for a modern reader to understand.]]
* Played ridiculously straight in ''Literature/HonorHarrington'', where everyone speaks Standard English, unless they happen to represent a specific culture/country in real-world Earth. In which case they'll supposedly speak that language and dabble it into their Standard English that they otherwise speak all the time. It's stated that sound recordings have slowed linguistic change to a crawl. Enough that Honor has no problems reading [[ShoutOut C.S. Forester's]] ''HoratioHornblower'' and the only problem she has is in dealing with the archaic units of measurement.
** In some places it is clear TranslationConvention: The Republic of Haven speaks French, the Andermanni speak a bastard German-Chinese language, San Martin spoke Spanish until the Republic of Haven came in. Most language issues are handwaved due to good translation software.
** In another Creator/DavidWeber book, ''Literature/TheApocalypseTroll'', a character from 400 years in the future is stranded on modern Earth. It's stated that the advent of widespread sound recording pretty much stabilized the language, but she still has a tendency to slip into incomprehensible future slang (generally leaving out syllables in confusing places: "Mister" becomes "Ster", for example).
** In Literature/{{Safehold}}, it's explicitly mentioned that the spoken language of Safehold has drifted in 800 years and the protagonist has to learn the new pronunciations before venturing out. The written language has apparently remained stable though.
* Addressed in David Severn's 'The Future Took Us' in which the protagonists only gradually realise the locals are speaking a futuristic version of English. "Bread" has become "brade" and "man", "mun".
* Played straight in the ''Literature/{{Spaceforce}}'' universe, where Earth is at the centre of one of the three galactic superpowers and everyone in that Union speaks, or at least knows, a language that's stated to be English. Apart from a few buzzwords, it's identical to the English of today.
* Addressed in Leo Frankowski's ''Conrad Stargard'' series. When Conrad goes back in time to 13th-century Poland, he realizes how lucky he is to be there, where the language hasn't drifted very much in 700 years, as opposed to England, where he would be completely incomprehensible. [[CriticalResearchFailure Which is just as much of a bull as you might expect]].
** Frankowski tends to forget that the characters are supposed to be speaking Polish and not English so to a Polish person reading the books in English some of the conversations make no sense since they use English puns or language conventions. Some of them being also anachronistic.
* In the Czech sci-fantasy book ''Divocí a zlí'' (''Wild and Dangerous''), the protagonist (who in the backstory comes from a post-apocalyptic future, and yet understands modern Czech) ends up helping Alfred the Great fight off some Danes and Swedes. And has no problem understanding and communicating with the locals. To put into perspective, Beowulf was written somewhere around that time.
* In the [[Literature/CommonwealthSaga Commonwealth Saga/Void Trilogy]], regeneration allows essentially eternal life - so the centuries old aristocracy maintains the general vernacular.
* Averted ''big'' time in Literature/ACanticleForLeibowitz. By 26th century, Modern English barely exists and by 3174 it is as dead as Latin. The story concludes in 3781 and at this point, due to centuries of LanguageDrift, there is at least a ''dozen'' of mutually unintelligible languages that emerged from English in North America alone, none of them considered "[[CommonTongue common]]".
* Played straight with Eternal Russian in the NoonUniverse novels by the Creator/StrugatskyBrothers with the crew of an experimental [=FTL=] starship that accidentally traveled to the next century. Nobody ever mentions any linguistic problems. Considering that the story focuses on the awe-inspiring (or just cool) technological advances, which tend to shock even contemporaries, minor linguistic problems are likely to be overshadowed.
** The same happens in the TimeTravel segment of ''Literature/MondayBeginsOnSaturday'' where an {{Antimatter}}-powered relativistic starship leaves Earth in mid-21st century and returns several thousand years later. Similarly, the girlfriends of some of the astronauts opted to become {{Human Popsicle}}s and are thawed out around the same time. None of the 21st-century characters have any problems communicating with future humans. Also there are AliensSpeakingEnglish (in another galaxy, no less). This is because the segment is a hilarious [[TakeThat mocking]] of overused futuristic SF tropes. If you squint hard enough, you can even recognize the originals.
* ''Literature/ReturnFromTheStars'' mostly plays this straight, though after 127 years there's some FutureSlang, and there are scrolling ads (?) displaying confusing words that sound vaguely like corporate trademarks.
* A particularly bad case in ''Literature/SwordOfTruth''. The High D'Haran (their Latin) has many dialects from different times, despite being mainly a scholars' language. However, the New World and the Old World have the exact same ''common'' language despite being separated for ''3,000'' years.
* In Creator/EdmondHamilton StarKings duology, the language of the future is based on English, and can be learned quite fast by a modern man. Quite reasonable - except we are talking about 2000 ''centuries'' in the future.
* In the first ''Literature/{{Dinotopia}}'' book, the protagonists have trouble communicating with everyone else on the island because they were the first newcomers to land there in some while. They meet a native girl who uses "a language in which I seemed occasionally to hear a familiar word," and when one protagonist tries speaking to her in English, French, and German she seems to catch a few words but is just as mystified. A local polyglot figures out what the protagonists speak in - "''Ank- ayyank-leesh. Yank-ank-kee.''" - and a man is produced who is "fifteen mothers English", aka fifteen generations removed from English ancestors, and knows an archaic form of the language, to translate for them and help them learn the dialect, which is a blend of many.
** Other works in the setting (except perhaps the 1995 computer game that no one remembers) which feature new arrivals washing ashore play it utterly straight, with said arrivals showing up speaking the same language as the locals.
* In the ''Literature/GreatShip'' universe, English appears to have died out, but whatever has replaced it seems to be very static, courtesy of pretty much [[SocietyOfImmortals every speaker being effectively immortal]]. The only language drift would be caused by isolation due to all forms of travel and communication being slower-than-light. One exception is in the novel ''The Memory of Sky'', set on a LostColony of mortals. When they discover a hatch on their HollowWorld with unknown text, they have to go to their oldest writings to decipher it. [[spoiler:Turns out that their entire world is a penal colony and the ''other'' bit of undecipherable text they discover is the world's [[ThrownOutTheAirlock purge button]]]].
* ''Timeline'' (reference in the film section above) had a scholar who had studied the period French extensively and was the only one who could really communicate, and even then he had a great deal of difficulty.
* Played frustratingly straight in ''Literature/TheWheelOfTime'', where cultures that have been entirely isolated from one another for upwards of a ''millennium'' have nothing more than a slight accent to contend with.
** WordOfGod was that the language itself didn't change in Randland that time because White Tower had stayed a (mostly) continuous institution and exerted its influence all over. The Seanchan kept the language fairly constant because of the ruling powers tightly controlled education to exert power. It's mentioned a few times in the book that people of Randland find the Seanchan accent to be virtually unintelligible until they're used to it.
* According to Creator/DaveBarry, grammar came about thanks to Chaucer:
--> We did not always have grammar. In medieval England, people said whatever they wanted, without regard to rules, and as a result they sounded like morons. Take the poet Geoffrey Chaucer, who couldn't even spell his first name right. He wrote a large poem called "Canterbury Tales," in which people from various professions - knight, monk, miller, reever, riveter, eeler, diver, stevedore, spinnaker, etc. - drone on and on like this:
--> In a somer sesun whon softe was the sunne\\
I kylled a younge birde ande I ate it on a bunne.
--> When Chaucer's poem was published everybody read it and said: "My God we need some grammar around here."
* Averted in ''Pebble In The Sky'' by Creator/IsaacAsimov, where one of the (many) difficulties the FishOutOfTemporalWater protagonist faces is having to learn a new language.
* ''Literature/WeAreLegionWeAreBob'': Averted, but oddly so; 2149 English is nearly incomprehensible to Bob and modern readers. It's implied that [[{{Theocracy}} FAITH]] deliberately modified the language in an attempt to limit seditious ideas, but no detail is given.


[[folder: Live Action TV ]]
* In ''Series/StargateSG1'' and ''Series/StargateAtlantis'', there are cultures that lived thousands of years before English was born that speak it flawlessly.
** SG-1 began with people on other planets speaking different languages, mostly based on old Earth cultures. By the second episode they realized it wouldn't work with only one main character (Jackson) able to speak to the people, so it was changed.
* In ''Series/{{Sanctuary}}'' Will mentions this as evidence of why three woman claiming to have awoken from hundreds of years of sleep have to be delusional - they all speak perfect English. [[spoiler: As it turns out they simply used their tremendous psychic powers to learn modern English instantly.]] In the first episodes Helen and John's mode of speech is a clue as to their shared origin. Their English is perfectly comprehensible, but slightly archaic and formalized. They and Tesla have all exhibited some distaste for modern conventions of the language.
** Good luck picking up on the fact that Tesla is Serbian, given his near-total lack of an appropriate accent even in flashbacks. The only time this is ever mentioned is when the British government requests they stop [[spoiler:Adam]] and do it for their country, prompting Tesla to mention that he's not British.
* On ''Series/BabylonFive'', the official language of the Earth Alliance is English. A TranslationConvention is in effect, but it doesn't explain how the characters can get away with verbatim quotes of Abraham Lincoln (or, in Garibaldi's case, ''WesternAnimation/LooneyTunes'' cartoons).
** In one episode there is a delusional man claiming to be King Arthur, they figure out that he isn't who he claims to be because he speaks modern English. Though earlier UsefulNotes/JackTheRipper was portrayed with just a British accent.
** That said, ''Babylon 5'' is set in the 23rd century (2258-2263). The distinctions in accent between American and British date back from over 200 years ago; there's no reason to think they would be altered completely in 250 years.
* In one of the few ''Series/{{Primeval}}'' episodes involving human incursions, a 14th Century knight strays into modern London and speaks perfectly clear Essex English, as does the local back in his time whom the ARC scout questions. Despite the fact that what passed for English back then was actually closer to modern Dutch. Even the fact that the ARC's knowitalls can understand him when he speaks Latin is questionable: chances are that our pronunciation of Latin has drifted almost as much as the living languages.
* WordOfGod says that this was the case in ''Series/{{Battlestar Galactica|2003}}'', which was bit of a shock for the fandom who had comfortably assumed TranslationConvention to be taking place, considering that the show took place [[spoiler: 150,000 years ago]].
* The Czechoslovakian sci-fi series for kids ''Series/TheVisitors'' (1983) had a group of scientists [[TimeTravel who travelled from the year 2484 to the year 1984]], visiting a small Czech town and trying to retrieve a formula that would save the Earth. The human society was peacefully united and [[AliensSpeakingEnglish the main language of humanity was apparently Czech]]. Eternal Czech was not even an issue and communication with local people was more or less fine, save for some cultural stuff. Something as universal as FacePalm is apparently unknown on Earth in this vision of blissful and very much Star-Trek-esque future. Professor Richard thought that fore-head slapping is a form of greeting.
* There's an '''extremely''' ludicrous example, not featuring English, in the ''Series/DoctorWho'' story "[[Recap/DoctorWhoS19E2FourToDoomsday Four To Doomsday]]", in which the white Australian character Tegan is able to communicate in an Australian Aborigine language with an Aboriginal character who was supposedly abducted from Earth by aliens 40,000 years before her time. This is implausible not just on grounds of linguistic drift, wherein we have NO attestations or models of any languages spoken 40,000 years ago, but also because there are many different indigenous languages in Australia, most of them mutually unintelligible, and because it would be extremely unlikely for any urban white Australian (Tegan comes from Brisbane) to speak any Aboriginal language fluently unless they had made a special effort to do so for political or cultural reasons. In terms of plausability, it would be like being able to communicate with Cro Magnon man by virtue of knowing modern Hatian Creole.(Many fans assume that the [=TARDIS=] was tactfully translating for her and letting her think that she was speaking the same language.)
* In ''Literature/BlakesSeven'', not only does everyone in the future speak English, but they do so with a posh Received Pronunciation accent.
* On ''Series/{{The 100}}'', the characters who grew up on the Ark speak standard American English, having maintained continuity with present-day civilization, but the Grounders down on Earth, who've been living in a post-apocalyptic wasteland for almost a hundred years, speak a language called [[http://the100.wikia.com/wiki/Trigedasleng Trigedasleng]] that, while clearly derived from English, is virtually incomprehensible otherwise.

[[folder: Tabletop RPG ]]
* In ''TabletopGame/{{Rifts}}'' the dominant language in the former United States and Canada is called American, which despite the different name, is indistinguishable from Modern English. Despite the game taking place 300 years after the apocalypse, where uneducated humans live in scattered, mostly isolated communities, there have been no regional language shifts.
** In the ''Phase World'' setting, Galactic Trade Tongue Four is in fact the descendant of the English Language, where an English Speaker has roughly a 50% chance to understand Trade Four. Mind you, so much time has passed in the Three Galaxies universe that everyone has ''forgotten where Earth was''.

[[folder: Theatre ]]
* In ''Theatre/OneTouchOfVenus'', Venus speaks amazingly good English for an ancient Greek goddess who spent the last several thousand years as a statue. Though since she's a goddess, we can [[AWizardDidIt ascribe that to supernatural powers]].

[[folder: Video Games ]]
* Played straight in ''VideoGame/ChronoTrigger'' and its sequel, ''VideoGame/ChronoCross''.
** Strangely, in Chrono Trigger's Prehistory era, humans speak broken English, using bursts of short words and phrases rather than grammatically correct sentences. On the other hand, their evolutionary rivals, the dinosaur-esque Reptites, speak perfect English. Humans are also implied to have a second language, as Ayla claims that "Lavos" literally translates from her language as "Fire Big".
* Played straight in ''VideoGame/SkiesOfArcadia.'' All six cultures of the world (all of them centered under its six [[WeirdMoon magical, oddly-colored moons]]) are vastly different and some are quite physically isolated from the rest, and yet it seems that they ''all'' speak English/Japanese.
** There are variations on how certain people in certain lands speak (for example, the primitive Ixa'Takan tribesmen speak in simple English, while in the Japanese version, the text boxes display katakana and hiragana only), but it still plays straight.
* ''Franchise/{{Halo}}'': 500 years in the future, humans still speak 21st-century English, complete with present-day regional accents, e.g. Californian/Valley Girl ("It's totally hiding from us!"); Australian; and Mexican-American. It's indicated that other languages have also largely stayed the same, e.g. the Hungarian spoken in ''VideoGame/HaloReach'' is basically identical to the modern form.
* ''{{Freelancer}}'': Despite taking place in the year 3100, those who live in Liberty still speak American English, and those who live in Bretonia still speak British English.
** Since we never hear anyone speaking any other language, it is not clear if they are also Eternal German (Rheinland), Eternal Japanese (Kusari), and Eternal Spanish (Corsairs and Outcasts).
*** The only mention of Japanese is in Trent's diary entry made after [[spoiler:Ozu's HeroicSacrifice]] when he writes "sayonara".
* In ''VideoGame/WarriorsOrochi'', everyone just inexplicably speaks modern English/Japanese.
* The three-hundred-year TimeSkip in ''VideoGame/JakIIRenegade'' has absolutely no effect on the language.
* In the present (or near present) era of ''VideoGame/TheJourneymanProject'', which takes place 300 years in the future, everyone has (21st-century era) American accents, even in Australia.
* ''Franchise/TheElderScrolls'':
** In ''[[VideoGame/TheElderScrollsIIIMorrowind Morrowind]]'', in the Cavern of the Incarnate, the player will encounter the ghosts of the "[[ThePoorlyChosenOne failed incarnates]]," who thought that they were [[TheChosenOne the Nerevarine]] but were killed before they could fulfill the prophecy. They are each Dunmer from different time periods, yet the player is able to communicate with them all without issue.
** In ''[[VideoGame/TheElderScrollsVSkyrim Skyrim]]'':
*** At one point in the main quest you either have a vision of the past or travel back in time a couple thousand years. When you do this, you find that people speak the same sort of English they do in your time, though this may be a function of the vision/time travel, rather than a true case. It's fairly vague on this point.
*** From the ''Dawnguard'' expansion, there is Serana, who has been kept in stasis for so long that she is unaware of the existence of the Cyrodiilic Empire, yet not only speaks Tamrielic, but speaks it in a very modern, nonchalant dialect, and has no trouble socializing.
* In ''VideoGame/AsurasWrath'', a game with a story not constrained by reason or logic in all other aspects, Asura can no longer understand the language of humanity after 12,000 years in limbo, although he can still understand his fellow gods just fine.
* Played with in the ''[[VideoGame/{{X}} X-Universe]]'' series, where the CommonTongue of the three human factions is a variant of Japanese - the word organization and writing is backwards (Nikkonofune, for example, would directly translate into "Sunlight of ship")
** It averts this trope by mentioning that the name Argon is the result of eight centuries' worth of language drift from "R. Gunne"[[note]]the middle initial and last name of their effective founder Nathan Ridley Gunne[[/note]]. Similarly the name of the Goner fringe sect is vowel-drifted from "Gunner", also a derivation of Gunne.
** At the same time, it's played straight by the fact that the Terrans, Argons, and Aldrinites can easily understand each other despite each having been separated from the other for nearly 800 years.
* ''VideoGame/SlyCooperThievesInTime'' not only has the ''Ice Age'' raccoon capable of speaking modern English (well, in subtitles; in spoken words, he's TheUnintelligible), but even characters from around the globe, such as Rioichi and Salim Al-Kupar, who should really be speaking Ancient Japanese or Arabic or Sanskrit or something, speak with little more than JustAStupidAccent. Sir Galeth from Medieval England uses YeOldeButcheredEnglish.
* Zigzagged in the ''VideoGame/{{Fallout}}'' series. Thanks to the presence of ghouls who were alive before the Great War, the Brotherhood of Steel and civilized territories ranging from towns to the New California Republic, the English used in the 2200s wasteland would be recognizable to a 2077 American. On the other hand, tribals like the ones in Zion National Park and those a certain Edward Sallow moulded into Caesar's Legion have developed various, unintelligible dialects based on English and whatever other languages said tribals' forefathers spoke.
* Averted in ''VideoGame/TheLegendOfZeldaTheWindWaker''. Link [[LanguageBarrier cannot understand]] "ancient Hylian" from the era of ''VideoGame/TheLegendOfZeldaOcarinaOfTime''. In ''VideoGame/TheLegendOfZeldaTwilightPrincess'' Hero's Shade (aka [[spoiler:the Hero Of Time himself]]) speaks in a modern dialect, though somewhat formally, but that could be explained as him knowing it to converse with Link more easily.
* ''VideoGame/MassEffect'' is set almost 200 years into the future, and yet the only apparent changes to spoken English are a few technical terms and some slang. This looks to be carried on in ''VideoGame/MassEffectAndromeda'', even though that game will be set several centuries after the events of the first trilogy.
** This is quite justified in ''Andromeda'', as the people travelling to the titular galaxy have spent the centuries between the games in stasis during their long voyage.
* Averted in ''[[Videogame/FireEmblemTellius Fire Emblem: Path of Radiance]]'' and its sequel ''Radiant Dawn.'' The language of the continent the games take place on, Tellius, has changed completely over the centuries of its history. The language spoken in the distant past, referred to as the "Old Tongue" or "Ancient Language," is unintelligible to most people in the current day, only being used by mages to cast spells. Only characters [[Really700YearsOld from that distant era]], the people of the far-off, isolated country of Hatari and the [[{{Animorphism}} heron laguz princess]] Leanne[[note]]Who spent decades in a magical slumber, and thus had no chance to learn the current language like her siblings did[[/note]] still speak it regularly, though a few of the present-day characters can understand it, but not speak it.
* We don't know exactly how long the Pale Bride in ''Visualnovel/{{Analogue A Hate Story}}'' spent in stasis, but it appears to have been at least a millennium. When she awakens, Korean appears to be exactly the same, and so much to her new family's annoyance, she has no trouble speaking her mind. Writing is another matter - since people have for some reason reverted to hanja, the Pale Bride is thought to be illiterate; in fact, she can read and write in hangul just fine, but she only knows a few Chinese characters.

* In ''Webcomic/SluggyFreelance'' Torg and Zoe have no problems communicating with the locals when they go back to [[TheMiddleAges Medieval Europe]]. On the other hand, Berk, a man from 25 years in the future, speaks such excessive future slang as to makes him nearly unintelligible. Even other people from his time can't understand him.

[[folder: Western Animation ]]
* You would suppose someone who died 1600 years ago would not be speaking modern English in ''WesternAnimation/DannyPhantom''.
* Played straight in ''WesternAnimation/{{Futurama}}''. In the year 3000, there are only a few notable language changes. "Ask" is now always pronounced "aks" (except when the writers forget it), and not just by rappers, and "X-mas" is actually pronounced as "ecksmass". Also, people still speak modern English in the year 50 million.
** Meanwhile, French is an incomprehensible dead language.
* In the 10th century, the main language of Scotland was Scots Gaelic. Despite this, the main characters of ''WesternAnimation/{{Gargoyles}}'' have no trouble communicating when they come to 20th century America. Later, Xanatos, Fox, and Xanatos' father have no trouble when they end up going back in time.
* In ''WesternAnimation/MegasXLR'', humans in the year 3037 speak modern English.
* Parodied in a time traveling episode of ''WesternAnimation/PinkyAndTheBrain'', where Brain, in his MobileSuitHuman, stumbles through all his conversations trying to remember which is "Thou, Though, Thee, Ye, They, Thine, ect" until one point he grabs a guy and just yells at him until he understands.
* The illegal immigrants from the future that come to present day ''WesternAnimation/SouthPark'' speak an unrecognizable language. [[AcceptableTargets And insist on bilingual education]].
* [[ZigZaggingTrope Zig-Zagged]] in ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' between Princess Luna and the Crystal Ponies. Both are products of pony life 1000 years ago, and Princess Luna is still shown speaking FloweryElizabethanEnglish in her appearance in "Luna Eclipsed". The Crystal Ponies, however, speak modern English with no trouble.
* This was actually [[LampshadeHanging lampshaded]] in ''{{WesternAnimation/Teenage Mutant Ninja Turtles|1987}}'', even thought the Trope was, indeed, used. ComicBook/UsagiYojimbo comes from an AlternateReality, from a world with a culture that mirrors FeudalJapan, "So ''[[SarcasmMode naturally]]'', he speaks English," says Raphael.
* In ''WesternAnimation/GIJoeARealAmericanHero'', Serpentor, right from the minute he drew first breath, spoke perfect English, even though ''none'' of the known historic figures who donated his DNA did so. (Of course, they used a ''lot'' of ArtisticLicense regarding history for his origin, even by the standards of that show.)
* Used in ''WesternAnimation/SamuraiJack'', though most likely with [[TranslationConvention Japanese instead of English]]. From the moment Jack lands in the distant future, he understands the locals perfectly and vice versa, though slang terms and "high five" confuse him.
** Jack was shown to have trained in many places around the world growing up before he first faced Aku, so presumably he's multilingual.
** In the episode where he has amnesia and doesn't even have combat-related muscle memory, Jack can still understand what fish-people are saying, though the Scotsman, a native to the time, has no idea. Perhaps going through the time portal also made him an {{Omniglot}}.

[[folder: Real Life]]
* Language change is a constant, which causes problems in real life -- the written form of the language tends to freeze at a certain point in development, while the spoken language keeps changing. [[CaptainObvious This causes definite problems in literacy]], even when merely limited to works of literature and legal documents. Eventually the literary and vernacular languages become totally different (called ''diglossia'' by linguists, Greek for "two tongues"), and later still the spoken language becomes the new written standard in place of the old one. This is what happened to Latin (replaced by Romance languages), Classical Chinese (replaced by Standard Mandarin) and Classical Greek (replaced by Modern Greek), among others.
** This is still the case with the Tamil language of South India. The written standard is still most the same as it was in around the 14th century, while the spoken form kept changing as normal, resulting a written form that contains extra vowels and diacritics that no one actually pronounces. This is further complicated by the fact that different social classes speak drastically different dialects that use different words derived from completely different roots to represent the same concept.
** This is somewhat the case with another Indian language,Hindi. Its written form is Sanskritized to an extreme extent like removing Persian, Arabic and English loan words with Sanskrit ones even when they were assimilated. This makes formal register Sanskrit in all but grammar.
** This is also somewhat the case with Arabic, where the written language is closely based on Classical Arabic, spoken at the time of the Qur'an. Colloquial Arabic differs greatly from it and there are several spoken dialects which are closer or farther apart from each other. A common debate among Arab intellectuals these days is whether or not to change the standard language; on one extreme, you have classicizers who think that all the modern dialects are rubbish, and on the other, you have local nationalists who want to break up the Arabic language altogether. Even the middle is somewhat divided: there are some who think the situation is fine as-is, or with minimal changes, while others advocate abandoning the current standard and creation of a new one based on the educated speech of Cairo (Egyptian Arabic is more or less universally understood, and Cairo is unquestionably the center of modern Arabic-language culture).
** Tibetan's standard orthography hasn't changed since the 1100s, and is essentially the same in all the Buddhist Tibetan-speaking regions. Amazing for a language that went from having complex consonant clusters and no tones, to having much simpler consonants and many dialects having developed tones to make up for lost consonants. (To give an example, the Dalai Lama's surname 'Gyatso' (generally pronounced ''chatso'') is spelled ''rgyam-tsho'' natively.)
** After the fall of the Roman Empire in the west, literate people (i.e., monks) continued to write in semi-classical Latin, while the spoken Latin language evolved into several Romance languages, though these were still considered "Latin". By the time anybody realized that what people were speaking was no longer Latin, it had become a SacredLanguage in the Catholic Church.
*** Also note that thanks to Humanist and early Renaissance scholarship there was a revival of classical Latin among scholars and scientists at the expense of the way Church Latin had evolved in the early and high middle ages.
** Also the case with Burmese, where there is a formal written language and a spoken form which is never written; they are pronounced quite differently.
** Officially, Afrikaans kept spelling in Dutch until a few years in to the 20th century, although some people spelled phonetically before then. One reason for this is that at the time, most people (even the majority of Afrikaans speakers) considered the language to be a dialect of Dutch. Since acknowledging a dialect's status as a language would usually go hand in hand with translating the Bible into it, many Afrikaans speakers were reluctant to do so, considering it disrespectful to translate Scripture into what was then still widely regarded as an uneducated-sounding, slang-littered dialect.
** It's also pretty much the reason that English spelling is so different from its pronunciation (many words, like ''name'', still retain Chaucer-era spellings - it was pronounced ''na-meh'' then). Combine this with etymological spellings (''homage'' from French), ''false'' etymological spellings (''island'' is not from Latin ''insula'' and didn't have an s until people thought it was), and the like, and you basically get modern written English.
*** The related Scots language, though, takes a more phonetic form, in part because no universally accepted standard has existed since the eighteenth century. Scots has also retained the Voiceless velar fricative or "hard ch", meaning that many of the superfluous appearances of "gh" in English- "through", "night", "thought", etc.- are actively pronounced in Scots.
** English gets a bad rap, but people tend to not mention that [[EverythingSoundsSexierInFrench French]] is also very different from its written form. To an Anglophone learner, it may seem as if half of every word is silent because they represent sounds which are no longer pronounced but included for etymological reasons.
*** While deducing written forms from the pronunciation is pretty much equally difficult, it's much easier to guess how a French word is pronounced once you learn the basic rules. English, on the other hand, has so many irregularities that it's almost impossible to have any kind of confidence about your guess. For example, "ou" in French is nearly always pronounced "oo" (except before a vowel as in "oui" where it becomes a more consonant-ish "w") while in English it can be pronounced "oo", "oh", "aw" or "ow" and the context gives no hints whatsoever.
*** Recently the French Academie has instituted spelling changes originally proposed in 1990 such as getting rid of the circumflex over vowels in many instances, changing the spelling of some words, and eliminating the hyphen in the middle of many compound words (''mille-pattes'' becoming ''millepattes'')
* Many [[strike:ideographic]] logographic written languages (such as Chinese or Egyptian hieroglyphs) remain readable at least to some degree even after ''millennia'', because often the written glyphs change much more slowly than the spoken languages. And when these are shared for writing across languages whose spoken forms have ''never'' been related (such as Chinese with the native vocabularies of Korean and Japanese adapted to Chinese characters), written texts can be partially readable across language boundaries because of shared meaning of glyphs.
** Further side-effect related to the above; because the words represent concepts, not noises which are interpreted as concepts in the language they represent, "glyph" languages can be taught in any language. You will have to throw in several English language constructs (articles come immediately to mind) and tense may be indicated differently in writing, but it is entirely possible to adapt Chinese characters for English. After all, they used them in writing Vietnamese and Korean, and still do in Japanese.
*** Actually, Chinese itself did for a long time depict the sounds, not concepts. Phono-semantic compounds make up the vast majority of characters - the radical signifies the semantic category, another character is used as a phonetic indicator. Since the time when those actually could be sounded out, however, Chinese has changed dramatically, making them much less indicative. For English, it would make much more sense to develop a native system, which as a thought experiment can for example be found [[http://www.zompist.com/yingzi/yingzi.htm here]].
** To show how much the Chinese languages have changed, historical linguistics has hypothesized that Creator/{{Confucius}} (which is just a Latinized form of Kong Fuzi) would have been called Kʰˤoŋʔ Kʷʰə during his lifetime. His courtesy name was even more different -- Truŋsnˤərs instead of Zhongni.
* The oldest dictionary of Japanese is ''[[http://en.wikipedia.org/wiki/Nippo_Jisho Nippo Jisho]]'', a Japanese-Portuguese bilingual dictionary of the late 1500s, showing both romaji, kanji and katakana of various words. The language drift and phonems which existed in the 16th century but are no more extant in the Modern Japanese provide good insight on the changes of the Japanese language. Also the ''meanings'' of the words have changed. e.g. ''samurai'' meant "noble" but ''bushi'' meant "soldier", "warrior".
* The Ugro-Finnic languages of Northern Europe are an interesting ''spoken'' example. Languages like Finnish and Estonian have been separated for millennia, but still have a large amount of remarkably similar words. Finnish in particular is famous in linguistics for being a slow-mutating language, with quite a few ancient loanwords mostly "frozen" in place from the time they were originally loaned. An example of this is ''kuningas'' meaning "king", which was loaned about ''three millennia ago'' from Proto-Germanic ''kuningaz'', of which the English word "king" is a far more mutated genetic descendant.
** The Finnish written language is notoriously different from the spoken variations and it's often thought, even by Finns, that the language has just changed as in the other cases. In fact, the Finnish written language is a rather rare example of one that's actually not based on any specific dialect. Since there were major arguments about which dialect to use as the basis, the intellectuals of the time ended up creating a new mixed dialect which had never actually been spoken by anyone before. So in some ways it's the other way around.
* Modern Icelandic speakers often have less trouble understanding thousand-year-old Old Norse than modern Danish speakers have understanding modern Swedish speakers. It's said that Leifr Eiríksson, the first European in America, would be able to be understood in 21st century Iceland.
** Considering that Iceland is quite isolated from the rest of the world helps. It also "helps" that Denmark and Sweden has been [[TigerVersusDragon enemies since the countries were formed]], heck, even longer back before they were properly formed. The government has actually manipulated the language (through schools and official texts) to be dissimilar.
* Sanskrit and Lithuanian are two notoriously slow-mutating languages in the Indo-European family. Sanskrit is so old that hymns composed before the time of King Tut can still be chanted with with near-perfect accuracy (although a large fraction of the word meaning themselves have been largely forgotten). An Indian priest from the time of Christ would be able to speak much the same Sanskrit and chant the same prayers as a modern Hindu priest. And as for knowing how the ancient speakers of the Indo-European languages talked, you need to listen to a Lithuanian villager talking (the Lithuanian language, separated by thousands of miles from Sanskrit, retains nearly identical words for many things, unchanged for millenia.)
** And there's the dying relative of Sanskrit, the Old Avestan language of the Zoroastrian religion, still chanted by the few surviving Zoroastrian communities still existent.
* For a straight example, the page quote itself. That's obvious in some cases, of course (eek? hadden prys?), but it's even trickier than it may appear; there's at least one false friend in there. "Nyce," to Chaucer, meant approximately what "stupid" means to us.
** UsefulNotes/JamesII supposedly described St Paul's Cathedral as "awful", "amusing" and "artificial" -- i.e. worthy of awe, giving pleasure and made with artifice.
** The English formal written language remains almost unchanged from the late 1800s on, but the spoken language is almost alien to a speaker from 1700. That said, unless both people were to speak entirely in their absolutely most informal kind of speech, they would have absolutely no trouble being ''understood''--the words would simply sound weird.
* Even though it ''did'' lose its incredibly complex and powerful tense system and is still leaking cases, Russian is a remarkably slow-changing language. A 12'th century epic poem "The Tale of Igor's Campaign" is still (barely) understandable to the modern speaker, for example. Even the 9-10'th century texts (like the Novgorodian birchbark letters) can be figured out by the readers uneducated in the language. Old Russian also gave birth to Ukrainian and Belarusian languages which are in some aspects (especially grammar) closer to Old Russian than modern Russian is (which was based on local version of liturgical (so called Church Slavonic) language rather than on vernacular Old Russian).
** In contrast Bulgarian has so drastically changed its grammar (for example, dropping all cases and acquiring a definite article) and also to a large extent its lexicon that to modern Bulgarians medieval Bulgarian texts look closer to Russian than to modern Bulgarian.
*** Medieval Bulgarian probably ''is'' closer to Russian than to modern Bulgarian, in terms of its characteristics, just like Old English works more like Icelandic than it does like modern English.
* Similar to the Finnish example above, Irish and Scots Gaelic are two Goidelic languages that diverged from one another 1600 years ago. Yet despite this, and despite both going through many many changes in that time, they are still mutually intelligible, and indeed share an estimated 70% of their vocabulary.
* A subtrope of creationists is Babelists, who believe in, yes, Eternal English.
* Hebrew is an example in that, while there are definitely obvious differences between Biblical and Modern Hebrew, one can nevertheless understand a lot of Biblical passages on the strength of a Modern Hebrew education alone. But this is kind of cheating, since Hebrew was revitalized as a vernacular in the 19th century, so it didn't have the same kind of organic growth as other languages would have.
** For instance, students in Israel going on a field trip to see the Dead Sea Scrolls can simply ''read them unaided''. It's helpful to think of the relation between Biblical and Modern Hebrew as similar to that between Shakespearean and Modern English.
*** They can read them, yes, but the changed meaning of many words can results in severe misunderstandings. As for pronunciation... Well, the Yemenite Jews still retain one close to the original, but the other dialects differ considerably. As an example; there are six letters which are supposed to be read differently at the beginning of the word or after a consonant - it's called ''dagesh''. Modern Israeli Hebrew only retains the rule for three - V/B, KH/K, and F/P. G, T and D are always pronounced as a ''dagesh'' form.
* The changing nature of languages has raised some issues on how to mark toxic waste dumps so that future civilisations who would not understand modern languages are not endangered by this. The proposed solutions range from plausible, like putting up obelisks with pictorial warnings on them; to breeding cats that glow when in range of radiation and hoping people associate it with danger; [[SerialEscalation to launching an artificial moon over the site.]]
** Of course, the real problem is that putting any sort of sign, even one depicting clear danger or death, will likely be interpreted as [[ShmuckBait "Hey, there's something interesting here!"]] and start digging. [[OutgrownSuchSillySuperstitions It's like how archaeologists pay little attention to the supposed "Curse of the Pharaohs" when opening Egyptian tombs.]]
* [[ZigZaggingTrope Zigzagged]] by Latin. It's a language that, despite being outmoded and dead, is still used for some purposes, but has undergone dozens of revisions. Despite that, vanilla Latin is still in use as a form of ''lingua franca'' in some circles (such as science) but is also being edited today due to a sparcity of words. Latin is included among the European Union's 'Official Languages' in which all documents are to be published. Which requires tricky transliteration when writing about concepts Latin had no 'words' for, such as in modern economic policies, industrial or environmental regulations, and farming subsidies. The Vatican has a whole department devoted to coming up with neo-Latin words for modern concepts.
* Similar to the Finnish example above, Romance languages remain extremely similar to each other (and some are in fact mutually intelligible) in spite of starting to diverge about 1,500 years ago. {{Justified}} by the deep interactions between the peoples speaking them, getting speakers of Spanish, Portuguese, French and the other languages to influence each other's vocabulary and grammar.
* Linguistic drift can happen ridiculously fast as a result of geopolitical divides. American English made several concerted efforts to distinguish itself from British English, to the point that several linguists believed they would evolve in completely different directions (which almost happened until modern telecommunications eased the drift), China and Taiwan are SeparatedByACommonLanguage after merely ''fifty'' years of not speaking to one another, and let's not get started on the variety of regional dialects you can find in any given country.
