* Hornblower and the Duchess openly discuss the Admiralty's super important dispatches which she's hiding. They are standing very close to a Spanish guard who's in hearing distance. Common soldiers probably didn't speak English, but Don Massaredo did and many a conversation was conducted in English. Luckily, he apparently didn't understand.

* An episode of ''Series/{{House}}'' has a Chinese mother and daughter talk in Mandarin so House won't understand. [[SubvertedTrope Of course]], he speaks it. Another House example has House blackmailing a guy in Mandarin. Presumably, if he didn't get his money he'd repeat what he said in English.

* On ''Series/HowIMetYourMother'', Ted and Barney befriend a Russian bouncer who takes them to an underground poker game. Ted ends up winning a lot of money from the other players who are very shady and dangerous looking. Just as it looks like Ted is going to get killed, the bouncer intercedes, shouts a few phrases in Russian and things quickly cool down. Ted and Barney are grateful to have made such a great friend but do not realize that he actually told the other players that he plans to rob Ted and Barney and will return everyone's money when he is done.
** And again when Barney first met Ted. He has him pretend to be his deaf brother to impress a girl. She starts signing at Ted (who signs back). Barney believes that Ted is playing him up to the girl, when he's really telling her that Barney's a liar, having her give him a fake number.

* On the first episode of ''{{Fringe}}'', a couple of Iranian businessmen speak Farsi to decide on a figure to pay Peter Bishop. Unbeknownst to them, he also speaks Farsi, and agrees to the figure they choose.

* Sports teams can employ this trope to keep their tactic a secret from the opposition. For example, South Africa has a whopping eleven official languages and English is generally used as the lingua franca. But when their sports teams play against English-speaking countries such as England, Australia or New Zealand, they sometimes use Africaans.

* In ''Film/MissionImpossible - Ghost Protocol'', a Russian character tells his wife in English that they need to get out of the country after the Kremlin bombing. His son, who's in the room, asks them why they're talking in English.

* In ''InglouriousBasterds'', the Jew Hunter speaks in English so the French-speaking Jews hiding under the floorboards can't understand what he and the farmer are talking about.

* In [[TheBoondockSaints the 2nd Boondock Saints movie]], Romeo speaks Spanish to his uncle to ask his uncle not to embarrass him in front of the MacManus brothers. He doesn't realize they know Spanish too.
* In ''CloseEncountersOfTheThirdKind'', Neary complains about this when Lacombe speaks to Laughlin in French.

* One of the earliest scenes in ''TheNightCircus'' is Hector and Alexander (presumably) issuing the challenge to pit Celia against one of Alexander's students... while Celia is standing right there. They pull this off through magic talk, but Celia cannot understand the adults while they converse and is oblivious to the topic of discussion.

-->'''Korialstrasz''':Do they know, my queen?
-->'''Alexstreasza''': No, my beloved. (Draconic) [[spoiler:

* On ''Impractical Jokers'' one time the mission was to get people to comment on bogus news stories in Times Square, and when approached two women commented "We don't speak English." It was lampshaded by the guy.

* NataliePortman [[http://www.youtube.com/watch?v=06NeSCpLhNs did this with Hebrew]] (at around 4:43) in an ''InsideTheActorsStudio'' issue, just to amuse herself. The Internet went nuts over this.

* Sports teams can employ this trope to keep their tactic a secret from the opposition. For example, South Africa has a whopping eleven official languages and English is generally used as the lingua franca. But when they play against English-speaking countries such as England, Australia or New Zealand, Africaans is sometimes used, especially in line out calls.

Alice, Bob and Claire all speak Language A, which is usually the language the work is written in or translated into, and may be the "common" language of the world. But Alice and Bob also speak Language B, which may be their native language, while Claire does not, enabling them to have private conversations if Claire is in earshot or they know Claire is eavesdropping.

To qualify, Alice and Bob must also speak a language Claire can speak, and Claire's inability to understand the language must be her only obstacle to understanding it; if she's deaf and unable to read lips, it doesn't matter whether she can speak Alice and Bob's language.

This trope can also be used to keep information from the audience, depending on whether a translation is provided. If the language is real and not translated, it can be a BilingualBonus.

[[AC:Fan Fiction]]

[[AC:Film]]

* In ''{{Braveheart}}'', Lord Hamilton attempts this using Latin during the first conference between Wallace and the Princess, assuming a Scotsman wouldn't speak or understand Latin. It doesn't work, since Wallace speaks both Latin and French.

[[AC:Live Action TV]]
* In the first season of ''Series/TwentyFour'', Jack and a police officer are pursuing a suspect, when they see a bystander and the officer yells in Spanish for the bystander to get down. The suspect takes the officer hostage, and Jack yells for her to fight back in Spanish. The suspect is captured but the officer dies in the process.
* An episode of ''Series/{{House}}'' has a Chinese mother and daughter talk in Mandarin so House won't understand. [[SubvertedTrope Of course]], he speaks it. Another House example has House blackmailing a guy in Mandarin. Presumably, if he didn't get his money he'd repeat what he said in English.
* In ''{{Frasier}}'', Frasier and Niles have to speak French around Eddie the dog in order to not get him unnecessarily riled up over a potential walk.
* In ''Series/{{Revenge}}'', Emily offers to act as a translator when Daniel is having dinner with a Japanese investor. The "investor" is actually Emily's mentor, and the two of them spend the dinner talking about Emily's revenge plots while Emily makes up translations for Daniel.
* On ''Series/HowIMetYourMother'', Ted and Barney befriend a Russian bouncer who takes them to an underground poker game. Ted ends up winning a lot of money from the other players who are very shady and dangerous looking.

Ted and Barney are grateful to have made such a great friend but do not realize that he actually told the other players that he plans to rob Ted and Barney and will return everyone's money when he is done.
* Happens and also discussed in ''NorthernExposure''. The older Native Americans all speak Tlingit when they don't want the youngsters to understand what they're saying. When Ed talks to Joel about this, Joel mentions a similar thing happening in Queens where Alter Kockers speak in Yiddish in order to keep secrets. Both Tlingit and Yiddish are dying languages; Ed decides to dub ThePrisonerOfZenda into Tlingit in order to preserve the language.
* Subverted on ''Series/{{Scrubs}}''. Turk learns Spanish, and listens in on a conversation Carla is having with her mother. He later tells her that he had learned Spanish.
* On the first episode of ''{{Fringe}}'', a couple of Iranian businessmen speak Farsi to decide on a figure to pay Peter Bishop. Unbeknownst to them, he also speaks Farsi, and agrees to the figure they choose.

[[AC:Real Life]]
* In WorldWarTwo, the Japanese used former students who had studied in the US to listen in to American radio transmissions, so Navajo soldiers were used to speak their own language, completely baffling the Japanese.
* Has been known to be TruthInTelevision, when both parents speak a language their child does not.
* In both world wars, Welsh regiments of the British Army spoke Welsh in clear on radio transmissions, knowing the likelihood of a Welsh speaker turning up on the German/enemy side was vanishingly small. This idea was copied by the Americans, who used native Americans as signallers to similarly confound Japanese and German intercepts. Unfortunately for Welsh regiments in WW 2, Welsh was thought of by the Nazis as a dawn-language of the Aryan peoples, and a School of Celtic Studies had been set up at one German university. Once the Germans cottoned on, they had a certain number of Welsh speakers available to monitor radio transmissions... the practice was, however, maintained by Welsh units in the Far East. It is no longer used by the British army as so many countries have universities that teach Celtic languages. It did not go un-noticed that a fairly recent enemy, Argentina, actually has a Welsh-speaking minority population. And at least one university in Northern Ireland has a Celtic Studies department offering Welsh language as a module. For that reason, Welsh units serving in Ireland were strictly ordered to observe standard radio operating procedure and not to think of using the old trck, as it is just too well known.

[[AC:Western Animation]]
* In ''TheBoondocks'' fastball episode the visiting Chinese team convince Huey to throw the game or else they'll get sent to death camps. This backfires when they gloat about it in Chinese in his presence, he responds (in Chinese) that he doesn't like to be laughed at. Cue asskicking.
* Invoked in an episode of ''WesternAnimation/{{Arthur}}'', where each little sub-group invented their own language and only let a few people in on it. Arthur & Buster, Francine & Muffy, etc. Eventually they were so separated that nobody could understand anybody else - except George, who spoke in English because he hadn't been invited into anybody else's private little club.
* In ''WesternAnimation/TheSimpsons'', Bart and Lisa speak in Pig-latin so Marge could not understand them. Of course, she does.
-->'''Bart''': Why don't you let us watch TV, and get her a Roofi CD?\\
'''Lisa''': [in Pig Latin] Bart, don't tell Mom Roofi has [=CDs=]!\\
'''Bart''': [in Pig Latin] Why not? What could go wrong?\\
'''Lisa''': [in Pig Latin] She'll buy them, stupid!\\
'''Marge''': [in Pig Latin] You know, I was young once, too.\\
'''Bart and Lisa''': [in Pig Latin] Crap.

'''Lisa''': [in Pig Latin] Bart, don't tell Mom Roofi has CDs!\\

* In ''WorldOfWarcraft'', completing the quests leading up to the [[WhamEpisode Battle of the Wrathgate]] leads to this exchange. A bug, however, temporarily alloweed players to understand the spoilered Drsconic part, which alluded to events that were only explicitly revealed in the Fall of the Lich King patch.

* In Fanfic/ACompleteTurnabout, Edgeworth and Franziska have a conversation about Franziska's past in German front of Phoenix, who only knows enough German to realize that Franziska does not like him eavesdropping.

* In MissionImpossible 4, one character tells his wife in English that they need to get out of the country after the Kremlin bombing. His son, who's in the room, asks them why they're talking in English.
* Attempted in the film version of LordOfTheRings TheTwoTowers, when Legolas tells Aragorn in Elvish that Helm's Deep's defenders are outnumbered snd will die, but Aragorn angrily yells in Common that he will die along with them before storming off.
* In IngloriousBasterds, the Jew Hunter speaks in English so the French-speaking Jews hiding under the floorboards can't understand what he and the farmer are talking about.
* Oddly averted in ShanghaiKnights. Chon Wang has a private conversation with his sister about Roy without knowing that Roy is eavesdropping. For some reason, they have the conversation in English rather than their native language, which Roy would not know.
* In {{Braveheart}}, Lord Hamilton attempts this using Latin during the first conference between Wallace and the Princess, assuming a Scotsman wouldn't speak or understand Latin. It doesn't work, since Wallace speaks both Latin and French.
* In CloseEncountersOfTheThirdKind, Neary complains about this when Lacombe speaks to Laughlin in French.

* Seen in ShanghaiGirls. Pearl and her parents speak Sze Yp - a Chinese dialect, but her younger sister May does not speak this dialect. When Pearl and May end up in Chinatown in the US, this language barrier prevents May from talking to the family she has married into, and pushes her out into the broader world
* In {{Dune}}, the deadly Count Fenring and his wife make heavy use of Obfuscating Stupidity, including punctuating their speech with lots of drawn-out hmmmmmmmmmmmmmms as an apparent Verbal Tic. When the book switches to their point of view, it turns out the humming is a code language to let them privately converse and coordinate their act in full view of everyone
* One of the earliest scenes in TheNightCircus is Hector and Alexander (presumably) issuing the challenge to pit Celia against one of Alexander's students... while Celia is standing right there. They pull this off through magic talk, but Celia cannot understand the adults while they converse and is oblivious to the topic of discussion.
* In TheGreatBrain at the Academy Tom is sent to a Catholic Boarding School for 7th grade (the town only has a 1-6 One Room Schoolhouse). Tom's brother Sewyn is there in the 8th grade class and takes delight in hazing Tom and the other 7th graders (as he was presumably hazed when he was in the 7th). At one point early in the book Sewyn exposits to another 8th grader, "[[AsYouKnow Remember]], speak in Latin when we don't want the 7th graders to know what we're saying." [Because the 8th graders had learned Latin when they were in 7th but the new 7th graders hadn't learned it yet.]

This trope can be subverted if, unbeknownst to Alice and Bob, Claire knows the language they are using. Such cases overlap with BilingualBackfire.
