masc. proper name, from French Louis, from Old French Loois, probably via Medieval Latin Ludovicus, a Latinization of Old High German Hluodowig, literally "famous in war" (cf. Clovis; for etymology, see Ludwig). Louis Quatorze (1855) refers to styles reminiscent of the time of King Louis XIV of France (1643-1715).
