valet (n.)
"personal man-servant," mid-14c. (late 12c. as a surname), from Old French valet, variant of vaslet "man's servant, workman's assistant," originally "squire, young man, youth of noble birth" (12c.), from Gallo-Roman *vassellittus "young nobleman, squire, page," diminutive of Medieval Latin vassallus, from vassus "servant" (see vassal). Modern sense is usually short for valet de chambre; the general sense of "male household servant of the meaner sort" going with the variant form varlet. First recorded use of valet parking is from 1959.
