Centurion: What's this, then? ‘People called Romanes they go the house?’
Brian: It ... it says, ‘Romans, go home.’
Centurion [thrashing him like a schoolboy]: No, it doesn't. ‘Go home?' This is motion towards. Isn't it, boy?
Brian: Ah ... ah, dative, sir! Ahh! No, not dative! Not the dative, sir! No! Ah! Oh, the ... accusative! Domum, sir! Ah! Oooh! Ah!
Centurion [pulling him by the ear]: Except that domum takes the ...?
Brian: The locative, sir!
[Monty Python, "Life of Brian"]
Used as a designation for "people whose languages descend from Latin" (1856), hence Latin America (1862). The Latin Quarter (French Quartier latin) of Paris, on the south (left) bank of the Seine, was the site of university buildings in the Middle Ages, hence the place where Latin was spoken. The surname Latimer, Lattimore, etc. is from Vulgar Latin latimarus, from Latin latinarius "interpreter," literally "a speaker of Latin."
