HYPERLECT — [Noun] The linguistic register of a hereditary aristocracy or socially closed elite, characterized by exclusive pronunciation, lexicon, and syntactical constructions. From the combining form hyper- (from Ancient Greek ὑπέρ (hupér), meaning "over, above") + -lect (from Ancient Greek λεκτός (lektós), "chosen, spoken"), thus literally "overspeech" or the speech of the overclass. Unlike acrolect (which denotes a standard prestige dialect accessible through education) or mesolect (which describes a fluid register of social compromise), hyperlect is a rarefied sociolect, defined by birthright and exclusive social performance. It is the precise, almost ostentatiously lazy rounding of an 'o' in a London club, the careful, distancing glide of a final 'r' in a Boston drawing-room, and the subtle omission of articles that transforms a statement into a shared secret—the audible architecture of a world that assumes it will never have to explain itself.
