Forms
rancidus (feminine rancida, neuter rancidum); first/second-declension adjective[1]
Etymology
It is formed from Latin ranceō (“to be rotten”) + -idus.[2][1][3] De Vaan finds no etymology for the verb,[4] and Etymonline calls it a word of unknown origin.[5] Isidore of Seville explained the adjective by its defect, saying that it makes people hoarse (raucus (“hoarse”)).[3]
Earliest recorded meaning
Lucretius is the first to use it,[4][6][7] of rotting corpses (rancida cadavera).[8][9]
Semantic evolution
Horace applies it to a rank boar,[9][10] and figuratively it meant offensive to good taste, nauseating:[2] Pliny the Elder uses it of a sight,[9] Juvenal asks what is more nauseating (quid rancidius),[9][8] Apuleius uses it of an old man and Prudentius of the songs of toothless old women.[10] Gellius has the adverb rancidē of contrived words.[9] In British Medieval Latin it is used mostly of spoiled food, such as rancid bacon or oil.[11]
DÉRom reconstructs Proto-Romance */ˈrankid-u/, continued in Sardinian ránkiđu, Romanian rânced, French rance, Catalan ranci, Spanish rancio and Portuguese ranço.[7] English borrowed the Latin word as rancid in the 1640s.[5]
