O.E. gelafian "wash by pouring, pour (water)," possibly an early Eng. or W.Gmc. borrowing of L. lavare "to wash," or its O.Fr. descendant, laver. L. lavare is from PIE *lou- "to wash" (cf. L. luere "to wash," Gk. louein "to wash, bathe," O.Ir. loathar "basin," Bret. laouer "trough," O.E. leaþor "lather").
