n. the light reflected from the moon

The word "moonlight" is a straightforward compound of "moon" (Old English mōna, from Proto-Germanic mēnōn) and "light" (Old English lēoht, from Proto-Germanic leuhtą). It literally means "the light of the moon." The verb sense, meaning to work a secondary job, emerged in the early 20th century, metaphorically alluding to working under the cover of night, much like the moon's subtle illumination.
