Etymology tree Proto-Indo-European *meh1-? Proto-Indo-European *mḗh1n̥s Proto-Germanic *mēnô Proto-West Germanic *mānō Old English mōna Middle English mone Proto-Indo-European *lewk-der. Proto-Germanic *leuhtaz Proto-West Germanic *leuht Old English lēoht Middle English light Middle English moonelight English moonlight The noun is derived from Middle English moonelight, monelight, mone lyght (“light of the moon; (heraldry) pattern of moons on the field of a heraldic banner”), from mon, mone (“moon”) (from Old English mōna (“moon”), ultimately from Proto-Indo-European *mḗh1n̥s (“moon; month”)) + light (“light”) (from Old English lēoht (“light”), ultimately from Proto-Indo-European *lewk- (“bright; to see; to shine”)). By surface analysis, moon + light. The verb is derived from the noun. Verb sense 1.1 (“to secretly leave premises without paying the rent”) is a back-formation from moonlight flit, while verb sense 1.2 (“to make a night-time attack on a tenant farmer”) is probably a back-formation from moonlighter. cognates * Dutch maanlicht * German Mondlicht * Scots muinlicht, munelicht * West Frisian moanneljocht
