Smart People Know Latin

""Whatever happened to Latin? At least when that made no sense, the church approved.""

- Giles, Buffy the Vampire Slayer

A special instance of Sesquipedalian Loquaciousness, and a perfect way to show that a character is not only smart, but refined, well- (formally) educated, and upper-class: have him be able to recite a Latin quotation flawlessly or read the dead language of the Romans as if it were his native tongue.

Supposedly, this shows that the character is of high intelligence or at least education, because Smart People Know Latin. Perhaps a reason for this is that since nobody speaks Latin, its remaining uses include a large proportion of "scholarly" applications, such as etymology, deciphering ancient texts, and mere quotation. While other languages have uses in these fields, their primary use - as a living language - crowds out other uses, so they are not considered as "scholarly."

Based on Truth in Television, as back during the Renaissance when classical Greek and Roman texts were rediscovered by Europeans, the ability to read the original sources was considered a good idea. Even earlier, most literate Europeans were members of the clergy, and therefore had Latin as a common language regardless of where they were living. Given the above, Latin became the default language of scholarship, and works on science and other learned subjects were often written in Latin as a sort of Lingua Franca. This is one of the reason science's language of choice for terminologies (especially in taxonomy) is Latin (with some Greek thrown in). The trend only started to fade during the 19th century, when English was beginning to become dominant.

Further, knowledge of Latin (and to a lesser extent, Greek) was a sign of a proper education as supplied by the British Public School system. In other words, only the wealthy could afford an education that included instruction in Latin, thus the modern connotation of class and education. Also, education in Latin in the present day has been linked to better language skills and test scores, and it is rare for poor students to take Latin unless it's a requirement. Not to mention how many higher-end schools and universities have Pretentious Latin Mottoes.

In modern works, knowledge of Latin will often be a part of Instant Cultured if a character is subject to Screw Learning, I Have Phlebotinum. Expect a newly intelligent character to suddenly be able to read Latin fluently, or at least ramble off the Latin roots of a word.

Of course, use of Dog Latin, or worse, Pig Latin betrays a classical sort of Delusions of Eloquence.

Film

 * In the film Event Horizon, the use of Latin by the captain of that ship on its Apocalyptic Log seems to be there partly to suggest what an educated guy he is, although it's the mistranslation of one of the quotes by the protagonists that turns out to be relevant to the plot.
 * Scarlet from Iron Man 2 speaks multiple languages including Latin, which impresses Tony. Pepper, corrects him in saying no one 'speaks' Latin, as it's a dead language (which isn't true, because all that makes it a "dead" language is that people don't have it as a first language and thus it doesn't change).

Richie: Latin.

Policeman: Latino? Thought he was English!"

 * in Withnail and I, Withnail and Monty engage in some prep-school Latin badinage at the less highly educated I's expense.

 * President Bartlet on The West Wing, who is a giant nerd, understands Latin enough that he can spontaneously compose prayers in it.
 * Though he is a Catholic (by choice, not birth), studied at Notre Dame, and wanted to be a priest at first.

 * Cupid (1998 version): A love-lorn professor and Trevor Hale (who believes he is and/or may actually be Cupid) are discussing picking up women in a bar.

Trevor: ...dormit in vacuo lecto."

 * Dr. Huang, The Shrink / The Smart Guy / Mr. Exposition on Law and Order SVU effortlessly steps in to correct a mistranslated Latin word in the episode "Silence".
 * It's a running gag on QI to make fun of Stephen Fry's perceived posh upbringing. On one occasion, Alan made a joke about him knowing the Lord's Prayer in Latin, to which Stephen responded by quoting the first line of such at high speed. Here's the clip
 * An episode of Sliders had the protagonists end up in a world where being smart and well-educated is cool (they pass a punk on the street with a boombox blasting classical music). Sports are all a mix of physical endurance and knowledge (kinda lends a whole new meaning to the term "mathlete"). Quinn in this world is a well-known athlete and a slider (although, ). He's also involved with some unsavory types. The episode's Big Bad is a mobster who constantly likes to quote phrases in Latin and gets annoyed when the others have no idea what he said. At the end of the episode, right before sliding, Quinn turns around and spouts a phrase in Latin, which turns out to be an insult. Of course, it's entirely possible that many people know at least some Latin in this world, given the obsession with intelligence.
 * Gil Grissom has done this a time or two on CSI-his insect names are most common, but there has been once or twice besides that.

 * Methos on Highlander. Justified since he was alive back then and lived in the Roman Empire for a while.
 * Apparently Latin is part of the curriculum at Starfleet Academy for some reason, as one episode of Star Trek: The Next Generation reveals that Wesley Crusher is studying it, and in another episode, Counselor Troi suggests that Picard, who's been turned into a child in a transporter accident, can go there to "brush up on [his] Latin."

Literature

 * Dorothy L. Sayers' Lord Peter Wimsey and Harriet Vane. They trade all sorts of learned quotations, but Latin is part of the deal. The last time he proposes marriage to her (in Gaudy Night), he does so in Latin while wearing his cap and gown (he took a First at Balliol). She accepts in the same language: "Placet." One of his frequent terms of endearment for her is "domina" (a feminine form of "dominus" "master") meaning "lady" or "mistress".
 * The the Aubrey-Maturin series, this is invoked in universe. Stephen Maturin is a physician that speaks Latin (along with a half a dozen other languages) and he will often use Latin around patients both to keep them from knowing what he is saying (when he is talking to another physician or an assistant who also speaks Latin) and because patients are reassured by the fact that their doctor is learned enough to speak Latin. The crews of the ships he serves on often brag that their ship has a real physician that speaks Latin and Greek.
 * Note that these were the times when surgeons and physicians were two radically different occupations, surgeons being little more than half-literate artisans who could let the blood, put on the leeches, extract the tooth or perform a field amputation. Having a real trained doctor on the ship (which was required to have a surgeon, not a physician) was a rare luck indeed.
 * Vlad Tepes and Elizabeth Bathory are apparently writing to each other in Latin in Count and Countess.

Web Original

 * Phase (Ayla Goodkind) of the Whateley Universe reads Latin, ancient Greek, and Middle English, all part of his classism and upper-upper-class upbringing in private schools. He also speaks several modern languages, and is a snob about it.
