		randomn.adv.adj. Origin: A borrowing from French. Etymon: French randoun. Etymology:  <  Anglo-Norman randoun, raundun, raundoun, Anglo-Norman and Old French, Middle French randon, randun, Middle French rendon speed, haste (12th cent.), impetuousness, violence (a1356), probably  <  randir   to run fast, gallop (12th cent.), further etymology uncertain: perhaps  <  the same Germanic base as rand n.1   (see further  Französisches etymol. Wörterbuch XVI. at rand).With use in phrases (see sense  A. 1) compare Anglo-Norman and Old French, Middle French de randon  , etc., at speed (a1170), Old French, Middle French de grant randon   very quickly (13th cent.), Middle French de grand randon   impetuously, violently (a1356), Anglo-Norman en un randun   in rapid succession, one after another (c1230 or earlier), Old French, Middle French en un randon   in one go, uninterrupted (12th or 13th cent.), Anglo-Norman a grant randun   in great haste (late 12th or early 13th cent. or earlier). The change of final -n   to -m   appears to be a development within English; compare ransom n., and see further  R. Jordan Handbuch der mittelenglischen Grammatik (1934) §254. The extremely rare Old French form random (see  F. Godefroy Dict. de l'ancienne langue française (1880–1902  ) at randon) is probably unconnected.
