Pronunciation

  • Classical: [ˈpʰal.lʊs][1]
  • Ecclesiastical: [ˈfal.lus][1]

Forms

phallus m (genitive phallī); second declension[1]

Etymology

It is borrowed from Ancient Greek φαλλός (phallós, “phallus”),[2][3][1][4] which Wiktionary takes to be likely from Proto-Indo-European *bʰel- (“to blow, swell up”), comparing follis “bag”.[1] Köbler and Etymonline also connect it with this root.[5][4]

Earliest recorded meaning

It is first found in Arnobius, for the figure of the male member carried about at the festival of Bacchus as a symbol of the generative power of nature.[2][3][5]

Semantic evolution

Augustine mentions it in the City of God in the same cultic sense.[2][6] Conte also gives the sense “male member” itself.[6] English took the word from Latin in the 1610s for an image of the penis.[4]

  • 297–310 AD – Arnobius uses it for the figure carried at the festival of Bacchus.[2][3][5]
