[Alteration of French réveillez, second person pl. imperative of réveiller, to wake, from Old French resveiller : re-, re- + esveiller, to awake (from Vulgar Latin *exvigilāre : Latin ex-, ex- + Latin vigilāre, to awake from vigil, awake; see weg- in Indo-European roots).]
1644, from Fr. réveillez (vous) "awaken!" imperative plural of réveiller "to awaken, to wake up," from M.Fr. re- "again" + eveiller "to rouse," from V.L. *exvigilare, from L. ex- "out" + vigilare "be awake, keep watch" (see vigil).
