means A personal manservant who attends to a gentleman's clothing and grooming, or, in modern usage, an attendant who parks cars for guests at hotels, restaurants, and events.

from From French valet, meaning a manservant or attendant, which traces back through Old French valet and vaslet to a diminutive of vassal — itself from Medieval Latin vassallus, a servant or retainer, possibly of Celtic origin. So the word carries the old feudal echo of one who serves a lord, eventually shrinking from manor halls to hotel curbs, where the only fiefdom involved is a parking lot.
