Forms

genou m (plural genoux)[1] Old French singular genoil (1080), plural genolz (end of the 10th century), genous (1273); genou was drawn from the plural about 1360.[2][3][4] The Académie (1694–1740) also gave genouil, pronounced like genou.[5]

Etymology

It is inherited from Old French genoil, inherited from Late Latin genuculum (“knee”), a crossing of classical geniculum (“little knee”) with genū (“knee”), of which “geniculum” is the diminutive.[5][2][6][3][7][1] The modern singular comes from the plural “genolz”, “genous”, written “genoux”.[5][6] “Genū” corresponds to Ancient Greek γόνυ (gónu) and to forms in Indo-Iranian, and to English knee and German Knie, Rey links the name with the root “*gen-” “to be born”, after the custom of recognising a newborn by placing it on its father's knees, while the Petit Robert gives a root “*genu-” “joint”.[2][8][9]

Cognate with Romanian genunchi, Italian ginocchio, Occitan genolh, Catalan genoll and Portuguese joelho.[8]

Earliest recorded meaning

The Passion of Clermont (end of the 10th century) has the plural: De davant lui tuit a genolz “all on their knees before him”.[5] The Chanson de Roland has Sur son genoill en fiert son destre gant.[9]

Semantic evolution

À genoux is found literally in 1273 and figuratively, of a submissive attitude, in 1665, ployer les genoux is in Malherbe and se jeter aux genoux de qqn in 1531.[2][4] By analogy it named the joint of a quadruped's foreleg (1690) and, in technical use, a joint in general (1573 in seamanship, 1845 in mechanics).[2] Old French often said à genoillons for “on one's knees”.[9] Être sur les genoux, to be exhausted, is from 1900, and the knee of trousers from 1832.[4][10] A bald head has been un genou since 1842.[10]
