Pronunciation

  • Classical: [ɡɛˈnɪ.kʊ.ɫũː][1]
  • Ecclesiastical: [d͡ʒeˈniː.ku.lum][1]

Forms

geniculum n (genitive geniculī); second declension[1] The spelling genuculum is found in manuscripts of later authors,[2] and Medieval Latin also has jeniculum and geniclum.[3]

Etymology

It is from Latin genū (“knee”) + -culum, a diminutive.[4][2][1] The base goes back to Proto-Italic *genū and Proto-Indo-European *ǵen-u- (“knee”).[5]

Earliest recorded meaning

Varro (116–27 BC)[6] is the first to use it, in De lingua Latina, of the small knees of children, to which splints were tied to straighten crooked legs.[4][5]

Semantic evolution

Pliny the Elder applied it to the knots or joints in the stems of plants such as the reed.[4][7] In the sense “knee” it is mainly ante- and post-classical:[7] Tertullian speaks of praying on one's knees (de geniculis), and the Vulgate's Nahum has the knees giving way in fear.[7]

Medieval Latin used it for the knee itself, with no sense of smallness, and also for a degree of kinship.[3] Manuscripts of later authors often spell it genuculum.[2] English geniculate (1660s) comes from the derived adjective geniculātus.[8]
