The adjective is from Middle English prompte, from Middle French prompt and its etymon Latin prōmptus (“visible, apparent, evident”), past participle of prōmō (“to take or bring out or forth, produce, bring to light”), from prō (“forth, forward”) + emō (“to take, acquire, buy”). Doublet of pronto. The verb is from Middle English prompen, apparently from the adjective. The noun is from the verb.
