Word History

Etymology

Middle English luminarye "lamp, source of spiritual light," borrowed from Anglo-French luminarie, luminaire "celestial body, source of light, important person, lamp, candle." borrowed from Late Latin lūmināria, plural (later taken as feminine singular) of lūmināre "opening to let in light, source of light, lamp, torch, heavenly body, important person," from Latin lūmin-, lūmen "light, source of light, opening to let in light" + -ar, -āre, variant (after stems with an l) of -al, -āle, nominalized forms of -ālis -al entry 1 — more at lumen

Note: The earliest Anglo-French attestations, luminaries and luminaires in the Oxford and Cambridge Psalters, are also the earliest French attestations from any source. The vernacular outcome of lūmināria is lumière, which co-occurs in an early text (Chrétien de Troyes, Cligés) with luminaire, though the latter is found just once. — The Latin word lūmināre is attested once in the classical language, in Cato's De agri cultura 14.2. The Oxford Latin Dictionary translates it as "lamp," though the context, a list of items needed to construct and furnish a farm building, suggests that lūmināria have some relationship to windows.
