Pronunciation

  • Classical: [ɫuːk.sʊ.riˈoː.sʊs], [ɫʊk.sʊ.riˈoː.sʊs][1]
  • Ecclesiastical: [luk.su.riˈɔː.s̬us][1]

Forms

lū̆xuriōsus (feminine lū̆xuriōsa, neuter lū̆xuriōsum, comparative lū̆xuriōsior); first/second-declension adjective[1]

Etymology

It is from Latin luxuria (“excess, luxury”) + -ōsus.[2][3][1] De Vaan derives luxuria from an adjective *luxuros, built on luxus (“extravagance”), and traces that, if the etymology is right, to Proto-Italic *lukso- and Proto-Indo-European *lug-so- (“bent”): a bending, hence a lack of restraint.[4] Festus derived it from luxus directly.[3]

Earliest recorded meaning

De Vaan and Köbler date it from Cato,[4][5] who tells the farmer that his housekeeper must not be too fond of luxury.[2]

Semantic evolution

Of plants it means rank or luxuriant, as Cicero's luxuriant corn, and of land very fertile; of style, exuberant or extravagant.[2][6] Of people and their acts it is excessive or unbridled, as Livy's joy of the senators that was too unrestrained, and wanton, as Ovid's suitors.[2][6] Most often it means given to luxury and self-indulgence, and of things showing luxury.[2] Church Latin glosses it wanton, extravagant, wasteful,[7] and in Medieval Latin it means lustful or licentious.[8] English luxurious (c. 1300) first meant lascivious, through Old French.[9]
