Cunning Linguist

""Wow, Ty-K0...our blasters and force abilities were no match for these ancient runes - and you translated them so fast! Yes, mastery of language is truly the greatest weapon! Here, take this huge pile of credits and rare artifacts!""

- Bounty Hunter, Penny Arcade (referencing Tycho's character choice in The Old Republic)

The Squad or the Command Roster don't always have the luxury of operating in countries or planets where everyone conveniently speaks English, so it falls to the Cunning Linguist to be the interpreter with the locals, decode enemy transmissions, help them pass themselves off as enemy soldiers, and help interrogate captured POW's.

In The Squad, the Cunning Linguist is often a white collar officer who has been "just transferred" into the squad, rubs everyone the wrong way, and worse, is completely and hopelessly lost in an actual battlefield. In the Command Roster, they fit in better. Subplots involving the Linguist usually have them grow a spine. Other times the linguist was always a part of the squad, but has been hiding their talents out of fear their friends will think the linguist is like their enemy, or unapproachably intellectual.

May overlap with other squad archetypes. If their skill with languages is overplayed, they may become an Omniglot. It is also not uncommon for this character to be a Gentleman and a Scholar. Compare The Smart Guy.

A common subversion of this trope is to land the Cunning Linguist in a situation where he/she doesn't speak the language—often a ridiculously common one, like Spanish or French. Such people tend to have worked in intelligence, where the language skills required are generally more exotic. Another is to simply depict them as being bad at a given language they claim to speak well. See Informed Ability.

Can easily overlap with the Communications Officer.

This trope is named for the cunning most linguists display throughout a given movie, always saving the squad's collective asses with only their quick wit and quicker language skills, and is not at all a pun on the word "cunnilingus".

Anime and Manga

 * Subverted with Rock from Black Lagoon. His being a Japanese salaryman guarantees that he alone knows both English and Japanese. This led to a Narm moment when the head of a Russian mafia pretends to speak broken English so that he can translate a negotiation.
 * This is actually a result of the way the Japanese audio track worked out. In-universe, English is the primary language of Roanapur, but the voices are all in Japanese. Then, in the final arc of Second Barrage, when Revy, Rock, Balalaika and her team actually go to Japan. There, their seiyuus begin speaking (naturally broken) English whenever they are in conversation with Japanese-speaking characters, but vocalize in Japanese voices again when conversing amongst themselves. The English Dub matches events in-universe much better as a result, although now the Japanese characters have new English voice actors when conversing amongst themselves (and in some instances, when speaking directly to character who actually speak English, i.e. Chaka to Revy). One wonders why they didn't just preserve the Japanese characters' Japanese audio through the entire arc.
 * Lutecia of Magical Girl Lyrical Nanoha was revealed in StrikerS Sound Stage X to be very adept at reading and translating Ancient Belka when Vivio needed some help doing research on the Mariage. She had since been used in ViVid as the go-to person for Ancient Belka texts. Jail Scaglietti was the one who taught her the skill.
 * Inverted in A Certain Magical Index. It seems everyone but the main character is a polyglot (and the fact that the main character isn't makes him look like an idiot). It gets a bit absurd when we have to have a British middle school student translate Russian into Japanese for him.

Comic Books

 * Doug Ramsey from New Mutants was this trope taken to its most extreme example. A studybuddy of Kitty Pryde's, he turned out to have the mutant power to understand any language he encounters, in print, spoken, or otherwise transmitted.
 * This included computer code, and there were hints that Doug would have been the greatest hacker in the world bar none, if it weren't for that whole dying thing.
 * Now that he's been resurrected... sorta... it's shown that his powers extend to social cues, and he can perfectly interpret the relationships between people based on subtle gestures.
 * He should become even more broken if the writers ever realize that his powers should include perfect understanding of the languages of magic.
 * In the fan work "Copycat" by dogbertcarroll on fanfiction.net, he explicitly can't understand the nuances of interuniversal teleportation sensory data (which includes Illyana and an OC relative of Mimic identifying universes by things like "blue ranch flavor"). So that Doug Ramsey can't understand some magic.
 * X-Men examples:
 * Everyone who was on the team when Ilyana Rasputin first came to stay with them can speak Russian, a result of Xavier using high-speed psychic abilities to teach it to them. Similarly, he taught them Japanese when they went to Japan to attend Wolverine's wedding to Mariko Yashida.
 * Wolverine has learned many other languages during his incredibly long life. He is known to be fluent in English, Arabic, Japanese, Russian, Chinese, Cheyenne, Lakota, and Spanish, and has remedial knowledge of French, German, Thai, Vietnamese, Farsi, and Portuguese.
 * Kitty Pryde, in addition to learning Russian and Japanese from Xavier, is fluent in Gaelic, Hebrew, and German; she can also speak the languages of the Shi'ar Empire and the Skrulls.
 * Beast, being the brains of any mutant group he's in, can speak English, German, French, Latin, Italian, Spanish, Japanese, Arabic, and Russian, and Latverian (Latveria being the country ruled by Dr. Doom) fluently.
 * In the Hagar the Horrible comic, Lucky Eddie fills this role when necessary.
 * As part of his training, Batman also became something of a linguistic expert, and is fluent in several languages including English, Spanish, French, Russian, German, Japanese and Chinese, and can read and understand (to varying degrees of proficiency) others.
 * Superman can speak all human languages, his ability to learn such skills much sharper than a human's.
 * Wonder Woman can also speak all Earthly languages, plus a few no longer in use, like Ancient Greek, for obvious reasons. This helps immensely in her role as an ambassador for Themyscira.

Fan Works

 * "Lyra" Black from the Harry Potter fanfic All According to Plan by LysandraLeigh. She's a thirteen-year-old cross-dimensional Time Traveling version of Bellatrix Lestrange who finds herself plopped into Wizarding Britain just before the beginning of Harry Potter and The Prisoner of Azkaban; she eventually discovers a couple years later that she's an omniglot -- possessor of a magical gift that allows her to absorb and learn any language by simple exposure.  Unfortunately, she can't use it because the bond she made with a goddess of chaos at age five protects her mind so thoroughly that the talent can't pick up anything.

Film
"Wentz: "Mister Tyler, please... don't tell the other guys I'm half German. They'll hate me.""
 * U-571 has sailor Bill Wentz, he's perfectly fluent in German and helps get the crew aboard the titular sub to help steal the enigma machine. He wants to keep his skill a secret though for fear of alienating his friends.


 * Saving Private Ryan has Timothy Upham who is the naïve kid, dispatched from the officer pool to help find private Ryan. Spends the movie getting his hands dirty and learning to be a soldier, manages to end the movie a Badass sitting out the climactic battle because of a Heroic BSOD.
 * Hilariously, Upham's German is in fact terrible, despite the claim of the character that his accent is "clean, with just a touch of Bavarian".
 * His French isn't much better, particularly his grammar.
 * Eva Longoria plays one in The Sentinel. This is mostly an Informed Ability, and the one attempt for her to demonstrate her skills is unimpressive.
 * There are at least two examples of scholar-linguists that are not out of their element: The translator in The Bridge on the River Kwai, who is said to have taught South-East Asian languages in Oxford(?) before the war seems at ease in the jungle, and seems to be more at home there than the other commandos. And there is T.E. Lawrence, who learned Arabic during archaeological digs in the Levant before the Great War, and apparently went native to some extent.
 * Milo Thatch of Atlantis: The Lost Empire.
 * Stargate, which came before the series, had Daniel Jackson fit this trope to near perfection. He is a non-military scientist stuck together with a team of commandoes, and he annoys the other members of the squad. (Mostly because he trapped them on an alien planet...) His linguist skills do come in handy, though.
 * Star Wars has C-3PO, a protocol droid fluent in more than six million forms of communication, who ends up using these abilities once or twice a movie—not counting his conversations with Artoo or Chewbacca, who everybody else seem to understand as well.
 * In The Dirty Dozen, one of the reasons that Joeseph Wladislaw (Charles Bronson) was picked for the squad was that he was fluent in German.
 * Galaxy Quest lampshades this trope with Gwen Demarco, whose entire job is to repeat everything somebody says to the ship's computer.
 * And repeat what the computer says in response, also with appropriate lampshading.
 * Mouth plays this role in The Goonies. When they find an old Treasure Map annotated in Spanish, Mouth is there to provide a Conveniently Precise Translation.
 * Erik in X-Men: First Class is shown speaking German, French, Spanish and English within the first twenty minutes or so of the film.
 * Uhura in the Star Trek reboot, though she isn't really able to put her skills into action on screen. Not true of the original timeline Uhura.
 * James Bond shows signs of this, inasmuch as he's a one man squad, when dealing with Russian spies, French money launderers and Middle Eastern arms dealers. Moneypenny in Tomorrow Never Dies even drops the trope name when he is "brushing up on his Danish" though also using it with the innuendo intact.
 * You Only Live Twice establishes he excelled at languages in Spy School, when he refuses the Japanese phrasebook Moneypenny offers him because he doesn't need it.
 * Hilariously subverted in Eurotrip, where Scotty acts like one, but most certainly isn't. His botching of German is the reason for him going to Europe in the first place, and when he and his friends are broke and attempt to catch a ride to Berlin from a German truck driver, Scotty acts as the group's translator
 * Scotty at least puts a qualifier in the sentence before he starts talking to the driver: "I speak bad German."
 * Sharon is fluent in Italian in the 1990 version of Captain America, the only explanation for this ability being that she spent a summer in Italy once.
 * In Zulu, Adendorff gives cultural advice.
 * In Inglourious Basterds, Hans Landa shows fluent command of his native German, plus French, English, and it is implied, Italian good enough to spot accent issues in other non-native speakers. Helps that Christoph Waltz, who plays him, is in reality fluent in French, German and English.
 * Sofie Fatale in Kill Bill serves as this to the Crazy 88, being fluent in Japanese, French and English. As with the above example, her actress Julie Dreyfus speaks all three in real life, and spent many years as a gaijin tarento in Japan, even teaching French on NHK's educational channel.

Literature

 * In the young adult series by John Bellairs, recurring character Proferssor Childermass often helps shed light on the current mystery with his extensive knowledge of languages, from French, Spanish and German to Latin and Greek. He prides his knowledge of languages extremely, and at the end of the book Eyes Of The Killer Robot, he is very put out by the fact that he did not recognize Arabic writing on a sword, thinking instead that it was only decorative engraving.
 * Played With in the Discworld novel Jingo when the protagonists enter Klatch. While it is useful that some of them do speak Klatchian, and there is a Shout-Out to Lawrence of Arabia, in one scene the somewhat racist Sgt. Colon, who doesn't speak Klatchian, is able to temporarily fit in, both because he has tanned skin and because his own language, "Morporkian", has become the local lingua franca. It also helped that his (accidental) cover story was as a resident of a Klatchian town whose residents were a byword for stupidity: the locals believed him to be from Ur (also the name of a real city of ancient Mesopotamia) because that's what he said when they asked him.
 * Also in Discworld, Rincewind displays an amazing facility for languages (especially given his ineptitude at anything other than fleeing). Apparently he can scream for help in many languages, and just plain scream in many more. (Explained and shown to be important, as "Aarrrgggh" translates to many things including: "Your wife is a big hippo", and more vitally: "Yes, more boiling oil!")
 * Of course, his linguistic abilities were established even earlier on, in The Colour of Magic, causing him to become the Discworld's first tour guide after meeting Twoflower. Being the only person who can talk to Twoflower, he's not the first to try to take advantage of his willingness to part with gold, only the most successful.
 * Besides having a gift for self-serving cowardice equal to that of Rincewind, Harry Flashman's rise through the ranks of the British army is aided by his equally amazing facility with languages, giving him an advantage over many other officers who had no knowledge of the languages of the peoples they were conquering.
 * He's apparently also something of a Cunning Linguist in the other sense; on one occasion a dissolute Sikh queen prefaced an engagement with him by ordering 'Rai and The Python' to stand ready as her second course; once she was done with Flashman she gasped to her attendants instructions to stand these two gentlemen down for the night, and tell them not to bother coming in too early tomorrow either.
 * Flashman's mad polyglot skills let him down in Royal Flash, though, where he has to impersonate someone who speaks several languages including Danish, which is obscure and difficult enough that his hasty briefing in it can't see him through a short interview with a native Danish speaker.
 * In another World War II example, the Alternate History novel Variant Bis features a one-shot Cunning Linguist character, who was indeed a capable linguist, being able to translate even local slang of the enemy on the fly, but he was stuffed into the uniform straight from his university chair, so he was absolutely terrible as an officer.
 * And there's Joseph Porta in the Sven Hassel books. He and the other members of the 27th Panzer Regiment often find themselves behind Soviet lines deliberately or otherwise, and there's usually a scene where they unexpectedly bump into an enemy soldier and Porta's quick-thinking response is what gets them out (it's mentioned several times that Porta's Russian is actually quite atrocious, but as the Soviet army of WW 2 had a vast number of ethnic minorities who couldn't speak Russian either he didn't stand out).
 * In Dan Abnett's Gaunt's Ghosts novel Traitor General,  reveals he speaks Old Gothic—better than Gaunt can, even. Hidden Depths rather than a justifying skill.
 * In the Buffy the Vampire Slayer novel, Portal Through Time, the Scooby Gang takes a temporal trip to save Past Slayers from being killed out of history. Too many dead and the whole world changes. Fortunately, they only go to time periods where English is spoken (the Civil War) or Giles can speak the local dialect.
 * Barchuk in the Conqueror books fills this role at first, being a Mongol who speaks fluent Chinese; he also teaches the language to Temuge, allowing him to play the same role. Ho Sa, a Chin soldier who speaks decent Mongolian, may also qualify.
 * Bellis in China Mieville's The Scar fills this role on the ship, complete with being both cunning and unapproachable.
 * In Keith Laumer's Retief stories, the hero, Jame Retief, is often the only one who bothers to learn the native language on whatever world they're visiting, leading him to be the designated translator. This sometimes results in a variation of One Dialogue, Two Conversations in which he's carrying on two entirely different conversations with different sides who don't understand what the other side is saying.
 * Ransom, the protagonist of The Space Trilogy, is a Philologist. It's an extremely good thing, because he wouldn't have been able to learn the alien language otherwise.
 * Aleksandr Griboyedov, the main character of The Death of the Vazir Mukhtar, knows 16 languages, which really helps with his diplomatic career among other things.
 * The titular Greek Interpreter in the Sherlock Holmes story is a part of no squad, but he worms vital info out of a hostage without the hostage's captors being any the wiser - the key is likely that he uses written Greek to smuggle tidbits out during the conversation.
 * Harry Dresden occasionally relies on  as a sentient translation device.
 * Anne Mason wrote two YA novels about Kira Warden, a skilled linguistics cadet on a space station. She is so often absent on trips to gain experience with other cultures that she misses out on a lot of basic education, and her agemates in other disciplines assume that she's incompetent. They learn better.

Live-Action TV
"I speak German, Russian, and am fully conversant in Czech, and I have to move to the one city where half of the people are from Latin America?"
 * Though originally an archaeologist, Daniel Jackson in Stargate SG-1 often served this purpose—so it was a good thing he had lots of other talents, considering how common Aliens Speaking English were. Rather realistically, he was an expert on cultures, which is a skill commonly in possession of real-life military translators—and archaeologists, at least within their areas of expertise. He spoke twenty-seven languages with varying degrees of fluency, affect accents, and could also read the non-English alphabets used by the Aliens Speaking English. When he encountered aliens who didn't speak English, the fact that Sufficiently Advanced Aliens effectively founded most of Earth's culture and languages also helped him communicate with them.
 * Daniel Jackson did have a PhD in archaeology and primarily described himself as such, but his knowledge of languages and culture wasn't incidental. He also had PhDs in linguistics and anthropology (the holistic study of human cultures).
 * His knowledge of German he claimed to have comprised mostly of the word "Vater" (father) and even that was hard to understand. Though he wasn't actually speaking German, just pretending to be German.
 * Despite what he may believe, apparently his Russian isn't that good either, considering that one member of the Russian army opted to keep the conversation in English after hearing one sentence from him.
 * This role was later taken by his Suspiciously Similar Substitute, Jonas Quinn, after he left the show, though only for a season, then he was brought back.
 * Hoshi Sato in Star Trek: Enterprise was a language expert brought in for the times when the still-being-perfected Universal Translator couldn't do its thing. (And Hoshi started as kind of a wimp, being somewhat afraid of space travel itself, as the second part of the trope dictates.)
 * The Arab translator Tariq in the short-lived Iraq War TV Series, Over There
 * Meesh from Generation Kill is apparently this, but is so lackadaisical about it that his translations are consistently questioned.
 * Giles in Buffy the Vampire Slayer and Wesley and Lorne in Angel know not only human languages, but a whole whack of demon ones as well. Of course, they generally use their skill in deciphering texts, not actually speaking it.
 * In one episode of Buffy, we learn that Spike speaks Fyarl.
 * It is also implied that Spike understands Luganda.
 * And shown that he can read Latin (which actually makes some sense given his growing up in Victorian England, where he might have actually been expected to study it as a human).
 * Gunn later gets a demon language upgrade as part of his Wolfram Lawyer Status. Of course, like with all Buffyverse magic, it came with a horrible price. Including golf skills (as business deals tend to be made on the links) and a "whole mess of Gilbert & Sullivan" "for elocution" which he started singing at random times, seemingly without noticing it.
 * Angel himself doesn't speak any demon languages, but he speaks at least eleven human languages.
 * Harris in Sharpe speaks fluent Spanish - handy, considering the characters spend most of the series in Spain.
 * He is also fluent in French (also important as they fight French), Latin and Greek. But he's still a competent soldier though.
 * In Shogun, the story of an English pilot stranded in Japan, there are a few cunning linguists. Most of them are seen as villainous by the (Protestant) hero, being Jesuit monks. However, one, the Lady Mariko, is gifted with languages, being able to speak Japanese, Portuguese, and Latin fluently. She translates for Blackthorne (the pilot) and teaches him enough Japanese to get along by the book's end.
 * Blackthorne himself is a subversion: His native language is English, but he's fluent enough in Dutch to serve on a Dutch ship and fluent enough in Portuguese to learn another language through it. The subversion is that he initially doesn't know a word of Japanese (not to speak of cultural misunderstandings), rendering him unable to fill the Cunning Linguist's role as an interpreter for his crew. Whereas most Cunning Linguists go from mild-mannered to badass, he does it the other way around.
 * Band of Brothers has both David Webster and Joseph Liebgott as the cunning linguist, this case being translators for Easy Company. This skill becomes a tragic burden towards the end, when a linguist must
 * Though strangely enough there's an episode towards the end where Webster insists on shouting in English at a German shopkeeper. In the next episode he speaks it fluently again. This might've been because he was flying off the handle at the townspeople for claiming no knowledge of the nearby concentration camp.
 * Webster speaking in English was actually on purpose, as the writers felt the scene would have been much less effective with subtitles. In the scene he seems to understand what the man is saying, he just replies to him in English.
 * There's a funny bit in Barney Miller where Wojciehowicz briefly interprets for two elderly Polish men, caught dueling with swords in the park until they're able to pull themselves together. Naturally, Wojo's a beat behind and continues translating even after they begin speaking English.
 * Michael Westen in Burn Notice is fluent in Arabic, Russian, Persian, and Czech, has recently learned French and German, and even speaks a bit of Urdu. However, even though he grew up in Miami, he doesn't speak a lick of Spanish.
 * Same old story in The Closer: Brenda Leigh Johnson, who had apparently spent her early career working for the CIA in Central Europe:


 * It's surprising how little this trope is put to work in Quantum Leap, given that protagonist Sam Beckett is an expert in everything under the sun (the man even knows kung-fu), and sidekick Al flat-out declares that Sam speaks many languages (including, staggeringly, hieroglyphic Egyptian). In spite of all that, vanishingly few episodes called on Sam to speak anything other than English.
 * Apparently, time travel within one's own lifetime and NATIONALITY is possible.
 * In "The Leap Home (Part 2)" he goes to Vietnam, although he is an American soldier and doesn't have to speak Vietnamese
 * One episode has him leaping into a man married to a Japanese woman. In one scene, he surprises himself when he's able to converse with her in fluent Japanese, prompting the abovementioned revelation from Al about his fluency in many languages.
 * Ramsey in Threshold. His linguistic skills don't get much use, as the series stays in the US.
 * In one episode, he identifies where a pilot grew up by his exact accent.
 * Horatio Hornblower is shown to be fluent in French in the television movies, and in the earlier films acts as a translator for The Captain, who only is shown to speak English. He later learns Spanish as well (he was in a Spanish prison, so he had plenty of time and opportunity and little else to do.)
 * Before he learns Spanish, we get an interesting play on the trope when a Spanish officer and Captain Pellew are having a meeting, and Hornblower has to act as interpreter. Since Hornblower doesn't know Spanish, the Spanish officer speaks French instead for the sake of communication.
 * As for how he ended up in a Spanish prison, Hornblower tried to slip past a Spanish fleet he stumbled across in the fog by passing himself and his ship off as a French courier. He is informed that his French was actually very convincing; he only failed in his ruse because one of the Spanish officers personally knew the actual French officer who had been in command before the English captured his ship.
 * The trope was more or less averted in the novels, where Hornblower can understand French, but his ability to speak it convincingly is hindered by him being completely tone deaf.
 * Max Eilerson in Crusade.
 * In Farscape, Sikozu's species can't have Translator Microbes implanted, but they pick up languages very easily, to the point where Sikozu learns English mostly from Crichton pointing to things in the cargo bay and naming them, in addition to a few minutes of attempted conversation. When Moya's crew reaches Earth sans Crichton, her actual knowledge of English (as opposed to the others' reliance on Translator Microbes and halting attempts to learn the language) proves useful.
 * Caroline in Two Broke Girls has been depicted as speaking fluent Japanese and passable Arabic and Hebrew. This may be justified by her wealthy upbringing and her Wharton MBA.
 * Law & Order: Ed Green, who spoke fluent Spanish as well as a decent amount of French and Russian.
 * Strong Medicine: Andy mentions being fluent in at least 6 languages and is heard speaking two of them (French and Tagalog) with patients who don't speak English. She explains by having grown up with a father in the Army—frequent moves to other countries made it necessary to learn the languages in order to keep up.

Video Games

 * One of the more painful elements of Twilight:2000 is that, at some point, you need to speak every possible language. Not having a team member with the ability to speak, say, Tajiki, can make beating a mission impossible. Language is strictly a product of nationality. There's little to no rhyme or reason to when each language might be useful. The result? A strangely Pan-Eurasian team of Cunning Linguists.
 * Shad fills this particular role in The Legend of Zelda Twilight Princess. Though everyone in the game (presumably) speaks and reads the current dialect of the Hylian language, Shad is apparently the only person in the kingdom who reads and understands Sky Writing, the written language of the ancient race called the Oocca, and is therefore the only NPC who can help Link with that necessary portion of his quest.
 * Recruiting HK-47 in Knights of the Old Republic is necessary if you want a peaceful resolution on Tatooine because he is the only person on the planet who can translate into the Tusken tongue. His homicidal tendencies are just an added bonus. The Player Character also has shades of this. Carth comments that the amount of galactic languages you speak is pretty rare for a raw recruit, but should come in handy being stranded on the rear end of the Outer Rim. He's right.
 * Lara Croft from the Tomb Raider games, by dint of being an Adventurer Archaeologist, is fluent in/can read and understand several languages including ancient ones such as Greek and Egyptian hieroglyphics. Lara Croft: Tomb Raider Legend has her speaking Japanese, and the films have her speaking Mandarin, Cambodian and a Siberian dialect.
 * Mike Thorton in Alpha Protocol, which is one of the main reasons he got employed by the agency in the first place. According to at least one of his backgrounds (field agent), Mike speaks fluent Farsi, Arabic, French, Spanish, Italian, Russian, Mandarin (Chinese) and Japanese in addition to English. Translation Convention kicks into gear whenever you do, though.
 * In The Elder Scrolls V: Skyrim, your character being a Dragonborn can learn to speak the language of the Dragons, which allows him/her to use powerful language-related abilities. Non-Dragonborn can also learn to speak the language, but do so with greater difficulty. The Dragons themselves seem to know both the Dragon language and the basic language of Tamriel fluently.
 * Nathan Drake of Uncharted fame. He is fluent in English, Spanish, Latin and Indonesian, and has some ability in Arabic and Tibetan.
 * Cammy Meele of Ace Attorney Investigations speaks several languages, and is the only member of her flight crew who knows Borginian..

Web Original

 * From SCP Foundation;
 * SCP-030, "The Homunculus", is a super-intelligent Artificial Human who is fluent in in Ancient Greek, Latin, Italian, English, Spanish, and Portuguese. It can also speak two languages unknown to modern humans, although SCP-030 claims they "should be common knowledge."
 * SCP-542, or "Herr Chirurg" as he calls himself, speaks German, English, and French fluently, and has some knowledge of Polish and Italian.

Web Comics

 * Narbonic has ANTONIO SMITH, FORENSIC LINGUIST! He only gets the Bold Inflation treatment when his hat's on.
 * Denver Tadwick, Exiern.
 * Fighter of 8-Bit Theater displays incredible linguistic knowledge in this strip, and explains its source in the next one. Black Mage's exasperated response to this revelation lies in the fact that, 99% of the time, Fighter is a total moron.
 * Parodied in this filler strip of Keychain of Creation.
 * A running theme in Megatokyo, where the series starts with Piro being fluent in Japanese from playing lots of dating sims, Largo knowing zilch Japanese, Kimiko and Ping knowing zilch English, Erika and Miho being fluent in English and therefore capable of communicating with Largo, and Yuki clumsily speaking what little English she can master. Later on, Ping gets a translation module that renders English words as Intentional Engrish for Funny Japanese subtitles... initially taken from porn flicks, much to Ping's very great confusion. Eventually Largo corrects it and she speaks perfect English.
 * This Penny Arcade has page-quote potential.
 * Elly of Dubious Company fills this role by translating Prince Winsome and Prince Daunting's Purple Prose in the Evil Tower of Evil story.

Western Animation
"Candace: Just remember, Gaston said I will always be his cou de crayon. Ferb: You do realize that's French for 'pencil neck'?"
 * Despite rarely even speaking his first language, Ferb from Phineas and Ferb can speak Martian and Dolphin, which has helped in some of the boys' activities. He can also speak "British English" better than his American stepbrother, though apparently he's been away from England for too long to be entirely fluent.
 * It also appears that he can speak Japanese in "Summer Belongs to You".
 * And he's somewhat fluent in French, as he recognized a remarkably obscure 'term of endearment' in Run Way Runaway:

"Batman: Who are you working for? Kasnian Thief: (in Kasnian) You can't understand a word I'm saying and I wouldn't tell you anything if I could. Batman: (in Kasnian) I can...and you will."
 * The Teen Titans have a polyglot in Raven, who in Teen Titans: Trouble in Tokyo claims to be able to read "English, German, Latin, Romanian, Ancient Sumerian, and Sanskrit"...but not Japanese.
 * A potential example would be Starfire, whose species can instantaneously learn any spoken language via simple lip contact making out with a speaker of the desired language.
 * In the comics she learned English (and probably Romany) by tackling and kissing Dick Grayson...the beginning of what is still an on-again, off-again romance. The episode "Go" revealed she learned it the same way in the cartoon.
 * In the comics, where she also has this power, she admits it only requires any physical contact, but she prefers to do it "the fun way".
 * Batman, in Justice League Unlimited.


 * For someone who frequently acts like Dumb Muscle, Nathan Explosion is quite good at speaking French. Albeit with an extremely gravelly voice. Pickles also seems competent in the language.

Real Life

 * The US Army has an entire MOS (Military Occupational Specialty) and a university-level school devoted to foreign languages. In practice, however, finding the best linguists generally means recruiting native speakers. The military also employs huge numbers of contracted civilian linguists. Unless you are in a SOF (Special Operations Force) element, these linguists will be unarmed and fit the trope perfectly.
 * Troops in Iraq and Afghanistan have been taught local phrases to help "win hearts and minds".
 * If you speak to somewhat more jaded and cynical members of the armed forces about this practice, they will tell you that they have been taught local phrases in order to help them lie through their teeth to the locals.
 * A similar incident is talked about in the book Chasing Ghosts, by Paul Rieckhoff. The author, a vet of the current Iraq War, tells a short story of how his grandfather was born in Germany and immigrated to America in the 1930s. Fluent in German, he was drafted immediately when World War II broke out ... and was sent to fight against the Japanese. This example is not as ridiculous as it sounds, though: the Germans were masters of spycraft and infiltration, so sending a soldier with potentially conflicted loyalties to a different theater was a good idea. They did the same thing with Japanese-Americans who volunteered in the armed forces to escape the American internment camps.
 * There is also the case that a large number of army linguists in Iraq and Afghanistan today do not know Arabic (Iraq), Pashto, or Dari (Afghanistan). There is some logic to that, since no one expected to be in either place for very long (oops), and never know where they will get sent next. For decades, the most desirable language for military linguists was Russian, for obvious reasons. The personnel policies never changed due to, dare say it, bureaucratic numbers games.
 * Of course, given that not all of the people fighting in those countries are from those countries, it might be handy to have linguists for other languages present (for instance, they have found at least a few of the insurgents in Afghanistan to be Chinese). Whether or not that's why those linguists are in those countries, or if they're seeing much use for such circumstances, is another thing entirely.
 * On an individual level, few can compete with Israel's first ambassador to the United Nations and third foreign minister, Abba Eban. A South African of English and Dutch Jewish descent raised in the UK, Eban spoke no fewer than ten languages according to The Other Wiki. He knew Arabic--Arabic!--well enough to produce a good translation of at least one classic of modern Arabic literature into Hebrew, spoke English better than anyone Henry Kissinger had ever seen, and is reported to have had an impressive command of Hebrew, as well.
 * All Israelis past, say, elementary school speak English well enough to get by. You don’t have to ask people whether or not they speak English in Israel, which some find to be a neat perk.
 * Andrew Divoff, a Russian-Venezuelan actor you probably know best for playing Mikhail Bakunin on Lost speaks English, Spanish, Italian, French, German, Catalan, Portuguese and Russian. And he knew how to speak Romanian, but forgot when he had nobody to speak to with it.
 * Christopher Lee—as if he wasn't awesome enough already—spoke English, French, Italian, Spanish, and German; had proficiency in Swedish, Russian, and Greek; and if Sir Ian McKellen is to be believed, could handle a little bit of Afrikaans, Zulu, Japanese, Mandarin Chinese and Swahili! With his career with British Intelligence, he's probably the nearest the world had to a real James Bond.
 * British actor Jamie Bamber is fluent in Italian and French (no doubt helped by having lived in France as a child, and hilariously lampshaded in an episode of Law and Order UK where he butchers the language while trying to question a witness) and can pull off an American accent so convincingly that many people are shocked to learn that he's from London.
 * While it's not known how fluent he was, actor Paul Robeson studied Swahili, Bantu, Igbo, Yoruba, Zulu, Chinese, Russian, and Hindi.
 * In the memoir Japanese Destroyer Captain, Capt. Tameichi Hara describes having a communications officer who had been a Hawaiian native of Japanese descent and could listen in whenever Americans broadcast in the clear for some reason (that usually being apparently, something like calling for help in case they had to ditch a shot up plane). That same comms officer at one time was at pains to disguise himself when the ship was sunk, presumably because he was afraid of being prosecuted for treason if he got back to the US. Somehow or other he did resettle there so someone must have decided there were no hard feelings.
