mid-14c., requeste, "act of asking for a favor, service, etc.; expression of desire for something to be granted or done," from Old French requeste (Modern French requête) "a request," from Vulgar Latin *requaesita, from Latin requisita (res) "(a thing) asked for," from fem. of requisitus "requested, demanded," past participle of requirere "seek to know, ask, ask for" (see require).
From late 14c. as "that which one asks for." By 1928 as "a letter, telephone call, etc., asking for a particular song to be played on a radio program, often accompanied by a personal message or dedication."
1530s, "ask (someone) to (do something), express desire for something to be done;" 1560s, "express a wish or desire, ask to be allowed to do something," from request (n.) or from French requester, "ask again, request, reclaim," from requeste. The older verb was Middle English requeren (14c.), from Old French requerre and directly from Latin requiare. Related: Requested; requesting.
