Origin: 1300–50; (v.) Middle English < Medieval Latin prōmptāre to incite, Latin: to distribute, frequentative of prōmere to bring out, equivalent to prō-pro-1 + (e)mere to take, buy; (adj.) late Middle English < Latin promptus ready, prompt, special use of past participle of prōmere
mid-14c., from O.Fr. prompt (early 13c.), from L. promptus "brought forth, at hand, ready, quick," prop. pp. of promere "to bring forth," from pro- "forward" + emere "to take" (see exempt). Theatrical sense of "to assist a speaker with lines" is first recorded early 15c.
