Forms

lux n (rare plural luxuri)[1][2] It was also spelled lucs: Negruzzi wrote of „ciocoismul, lucsul şi corupția” “upstart greed, luxury and corruption”.[1][2] Early 19th-century texts have luxus: „Din oraşe iese şi naşte luxusul” “from the towns luxury comes forth”, wrote Mumuleanu.[1] Rare old variants are lus and lăxus.[1]

Etymology

It is borrowed from French luxe, together with the Latin luxus.[3][1][2][4] Ciorănescu and Tiktin name only the French word.[5][6]

French borrowed the word in 1607 from the Latin noun, which meant “excess in the way of living, splendour, pomp”; it is perhaps the noun of the like-sounding adjective meaning “dislocated”, so that it first meant growing crooked and then growing to excess.[7]

Earliest recorded meaning

The first record, of 1777, has the plural lucsuri in the sense “ornaments, jewellery”, in a document quoted by Furnică: „lucsuri de aur” “gold trinkets”.[1][2] A text of 1820 has luxus in the sense of costly display, and Tiktin dates lux to 1824.[1][6]

Semantic evolution

Early writers explained the new word: Golescu wrote that it covers all kinds of needless spending, and a newspaper of 1829 glossed it as spending on shiny things.[1] Negulici in 1848 defined it as great costliness in clothes, furniture and food.[8] The sense “ornament” fell out of use.[1]

From “costly display” come de lux “luxury, high-quality”, as in magazin de lux, and a face lux “to live or dress extravagantly”.[3][2] A-și permite luxul “to allow oneself the luxury” extends it to anything not strictly needed.[1] Figuratively it means abundance, as in cu lux de amănunte “in great detail”.[2][9] Regionally, from mașină de lux, it came to mean a car or a taxi.[1][2]

Usage notes

A face lux means to live in costly style, and especially to dress very expensively.[3][2] A separate word lux (plural lucși), borrowed from French lux, is the unit of illuminance, one lumen spread over one square metre; it is recorded from 1949.[3][2][10] An old, rare lux “light”, taken from Latin lux, occurs in C. A. Rosetti.[1]
