Etymology and origin of the Latin word phallus
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]
