Pronunciation

Forms

uterus m (genitive uterī); second declension[1]

Etymology

It is inherited from Proto-Italic *udero-, from Proto-Indo-European *(H)ud-ér-o- (“outer, sticking out”), a derivative of *ud “out”.[2][1] Cognate with Sanskrit उदर (udára, “belly”) and Ancient Greek ὕδερος (húderos, “dropsy”).[2][3] The /t/ for expected /d/ is unexplained: Walde and Hofmann suggested the influence of uter “leather bag”, while Hilmarsson thought it arose by syncope in the oblique cases.[2]

Earliest recorded meaning

De Vaan and Köbler date it from Plautus, who also has the neuter form uterum.[2][4] In Plautus Alcmena's labour pains begin in the womb.[3] Köbler dates Plautus c. 250–184 BC.[4]

Semantic evolution

It meant the belly or abdomen of persons and animals, and specifically the womb, and so pregnancy or the unborn child.[3][5] By transfer it was used of cavities like the womb, such as the inside of the Trojan horse, and of the bulging part of anything.[3]

Medieval Latin kept both senses, belly and womb.[6] English uterus was borrowed as a medical word in the late 14th century, and it passed in the same way into French utérus and Italian utero.[7][1]

Timeline

  • c. 250–184 BC – Plautus speaks of labour pains in the womb.[3][4]
