PIE word *upó The adjective is a learned borrowing from Late Latin sublūnāris (“sublunar, sublunary”) + English -ary (suffix meaning of or pertaining to forming adjectives). Sublūnāris is derived from Latin sub- (prefix meaning ‘below, beneath, under’) + lūnāris (“of or pertaining to the moon, lunar”) (from lūna (“moon”) (ultimately from Proto-Indo-European *lewk- (“bright; to see; to shine”)) + -āris (suffix forming adjectives denoting a pertaining to or relationship)). By surface analysis, sub- + lunary. The noun is derived from the adjective.
