lave [leɪv] v. i.
1.) To bathe, lit. and fig. (Oxford English Dictionary 2nd Edition).
Etymology: Two distinct formations appear to have coalesced(1) Old English had lafian, to wash by affusion, to pour (water), corresponding formally to Middle Dutch, Dutch laven, Old High German labôn (Middle High German, modern German laben), to refresh; cf. Old High German laba, modern German labe, refreshment. By some scholars the Old English, Dutch, and German words are considered to represent a West German adoption of Latin lavāre, to wash. This view involves some difficulty, as the numerous Old High German examples refer to refreshment by food, drink, or warmth, so that the assumed primary sense 'to wash', if it ever existed, must have been quite forgotten. The Latin origin, however, accounts well for the senses of the Old English word, which perhaps may be only accidentally similar in form to the continental words. (2) In Middle English the representative of the Old English verb blended indistinguishably with the verb adopted from French laver from Latin lavāre = Gr. λούειν, from Old Aryan root lou-, to wash (whence lather).
"And I am seized by long-unwonted yearning
For that domain of spirits calm and grave,
To tenuous notes my lisping song is turning,
Like Aeol's harp it fitfully would wave,
A shudder grips me, tear on tear is burning,
With softening balm the somber heart they lave;
What I possess I see as from a distance,
And what has passed, to me becomes existence."
