coxa

Etymology and origin of the Latin word coxa

Pronunciation

  • IPA (Classical): [ˈkɔk.sa][1]
  • IPA (Ecclesiastical): [ˈkɔk.sa][1]

Forms

coxa f (genitive coxae); first declension[1]

Etymology

It is inherited from Proto-Italic *koksā- (“hip”), inherited from Proto-Indo-European *koḱs-h₂- (“limb, joint”).[2][1] De Vaan notes that the word changed from masculine to feminine, perhaps under the influence of other names of body parts.[2] The Germanic family of Old High German hāhsina (“hollow of the knee”), often compared, goes back to a different form and does not belong here.[2][3]

Cognate with Old Irish cos (“foot”), Sanskrit कक्ष (kákṣa-, “armpit”), Avestan kaša- (“armpit”) and Tocharian B kakse (“loins”).[2][4]

Earliest recorded meaning

Its first author is Nigidius Figulus, in the 1st century BC,[2][5] who wrote that the trunk is supported by the hips, knees and legs.[6]

Semantic evolution

In Classical Latin it meant the human hip and an animal's haunch, and in Celsus and Pliny the Younger the hip-bone.[4][7] The land surveyors used it for a re-entrant angle or inward bend of a boundary.[4][8] In Late Latin it came to mean the thigh,[1] the sense continued in Italian coscia and French cuisse.[1]

Medieval texts use it mostly in anatomy and medicine for the hip-bone and hip joint.[9]

Timeline

  • c. 100–45 BC – Nigidius Figulus uses it.[2][5]
  • 1st century AD – Celsus describes stiff hips and the hip-bone.[4][6]
  • 23/24–79 AD – Pliny the Elder says riding is good for the stomach and hips.[4][5]
  • 1st–2nd century AD – Siculus Flaccus uses it for an inward angle of a boundary.[4]
  • 1706 – English borrows it as English coxa “hip-joint”.[10]
