Centurion: What's this, then? "People called Romanes they go the house?"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." "What Latin was to the learned, that their tongue was to laymen; hence latino was used for any dialect, even Arabic and the language of birds ...." [Donkin, "Etymological Dictionary of the Romance Languages," 1864].

Brian: Ah ... ah, dative, sir! Ahh! No, not dative! Not the dative, sir! No! Ah! Oh, the ... accusative! Domum, sir! Ah! Oooh! Ah!

Brian: The locative, sir!
