c.1300, "to ask a question, inquire," from O.Fr. requerre, from V.L. *requærere, from L. requirere "seek to know, ask," from re- "repeatedly" + quærere "ask, seek" (see query). The original sense of this word has been taken over by request. Sense of "demand (someone) to do (something)" is from 1751, via the notion of "to ask for imperatively, or as a right" (1380).
