Forms

πέος (péos) n (genitive πέεος or πέους); third declension[1]

Etymology

It is inherited from Proto-Hellenic *péhos,[1] inherited from Proto-Indo-European *pésos (“penis”), a neuter s-stem.[2][1][3][4] It is identical with Sanskrit पसस् (pásas-, “penis”).[2][3][4][5]

Cognate with Latin pēnis (“tail, penis”), formed with an n-suffix, and with Hittite pešan- (“man, male”).[2][4][3] With the o-grade and the popular suffix -θη (-thē), πόσθη (pósthē) has the same meaning.[4][2]

Earliest recorded meaning

It is first recorded in Aristophanes' Acharnians, as a coarse word of comedy.[5][4][6][7] Babiniotis dates it already to Archilochus, in the 7th century BC.[8]

Semantic evolution

It remained a colloquial word, frequent in Aristophanes.[6][7] Comedy also formed πεοίδης (peoídēs) “with a swollen member”, and Lucian πεώδης (peṓdēs).[4]

Modern Greek πέος (péos) is a learned revival of the ancient word, and it forms new compounds.[9][8]

Timeline

  • 5th–4th century BC – Aristophanes uses it in the Acharnians and other comedies.[5][6][10]
  • 2nd century AD – Lucian uses the derivative πεώδης (peṓdēs).[4]
  • Modern Greek – The word is used again as a learned borrowing from Ancient Greek.[9][8]
