c. 1200 (transitive), from Old English lafian "wash by pouring water on, pour (water)," possibly an early Anglo-Saxon or West Germanic borrowing (compare Dutch laven, German laben) of Latin lavare "to wash," or its Old French descendant, laver, or some confusion in English of the two. Latin lavare is from PIE root *leue- "to wash."
