From Middle English quiete, from Old French quiet (adjective) and quiete (noun), from Latin quiētus, past participle of quiēscere (“to keep quiet, rest”), ultimately from Proto-Indo-European *kʷyeh₁- (“rest”). Doublet of coy, quit, quite, and quietus. Largely displaced native English still in the sense of "with little or no sound".
