Forms

décorum m (plural décorums)[1]

Etymology

It is borrowed from Latin decōrum (“what is fitting, propriety”), the neuter of the adjective decōrus (“fitting, adorned”) used as a noun.[2][3][4] The adjective is derived from decor (“what is fitting, ornament”), from the group of decet (“it is fitting”),[3][5] which also gave décent.[3] The verb décorer belongs to the same family.[3][6]

Earliest recorded meaning

It is first recorded in 1587, in Pierre Crespet's Le Jardin de plaisir, for the rules of propriety.[2][3] Bloch and Wartburg and the GLLF give the Satire Ménippée (1594) as the first record, where a prelate wishes garder le decorum et la dignité du rang “to keep the decorum and the dignity of the rank” that he holds in the Church.[7][5][4]

Semantic evolution

Furetière records the phrase garder le décorum, to observe all the rules of propriety.[3] In the 19th century the word narrowed to official etiquette and protocol (1889, Pierre Loti).[2][3] At the same time, probably under the influence of décor and décorer, it took the sense of what adorns, a showy outward appearance (Balzac, 1835), which became pejorative: ostentatious luxury.[3][2]
