Pronunciation

  • Classical: [uːˈreː.tʰra][1]
  • Ecclesiastical: [uˈrɛː.tra][1]

Forms

ūrēthra f (genitive ūrēthrae); first declension[1]

Etymology

It is borrowed from Ancient Greek οὐρήθρα (ourḗthra, “urethra”).[1][2][3][4] The Greek word is a derivative of οὐρέω (ouréō, “to urinate”);[5][3] Etymonline says it was coined by Hippocrates.[6] Beekes traces the verb to Proto-Indo-European *u̯ers- (“to urinate”), an iterative formation from the root of Sanskrit and Avestan words for raining.[5]

Earliest recorded meaning

The first author the dictionaries cite is the physician Caelius Aurelianus, in his work on chronic diseases, for the canal through which urine leaves the bladder.[2][7][3][4]

Semantic evolution

It stayed a medical term.[4] Italian has it as uretra, from the Late Latin word.[4] English borrowed it in the 1630s.[6]

Timeline

  • 5th century AD – Caelius Aurelianus uses it for the urinary canal.[2][3]
  • 1630s – Borrowed into English as urethra.[6]

Meanings

Noun

  1. (medicine) The urethra, the canal that carries urine out of the bladder.[2][7][4]

Usage notes

Georges notes that the purely Latin expression for it was mictualis via.[7]
