Pronunciation

  • 5th-century BC Attic: /he.ós/[1]
  • 4th-century AD Koine: /eˈos/[1]
  • 10th-century Byzantine: /eˈos/[1]

Forms

ἑός (heós) (feminine ἑή, neuter ἑόν)[1] Epic genitive ἑοῖο, Boeotian ἱός, and Doric and other dialects ϝός.[2][3][4] The possessive ὅς is its shorter counterpart.[4]

Etymology

It is inherited from Proto-Hellenic *hewós, from an adjective made from the reflexive Proto-Indo-European *swé (“self”).[1][4] Beekes and Frisk explain this word and the possessive ὅς (hós) as adjectives made from the reflexive pronoun ἕ (hé, “him, her”): Proto-Indo-European *seu̯o- gave the epic form, and *su̯o- the dialect form ϝός (wós).[4][5]

Cognate with Sanskrit स्व (svá-, “own”), Old Latin sovos (later suus) and Lithuanian sãvas.[4][1]

Earliest recorded meaning

In Homer it means “his” or “her”, often with the stress of “his own”, as in τὸν ἑόν τε Πόδαργον “and his own Podargus” (Iliad 23.295).[2][6] It can be strengthened with αὐτός (autós): ἑῷ αὐτοῦ θυμῷ “in his own heart”.[2]

Semantic evolution

In a few Homeric passages it seems to refer to the first person, “my”.[6] After Homer it spread to other persons: Hesiod and Pindar use it for “their”, and Hellenistic poets such as Apollonius of Rhodes for “my”, “your” and “our”.[2][3]

It was a word of epic and lyric poetry and of some dialects, Doric, Boeotian and Thessalian; it is not found in Attic prose and only doubtfully in tragedy.[2][3]

Timeline

  • Homer – The Iliad and the Odyssey use it for “his own”, “her own”.[6][2]
  • Before the 6th century BC – Hesiod uses it for “their”.[2][3]
  • 6th–5th century BC – Pindar uses it for “his” and “their”.[2][3]
  • 5th century BC – Corinna writes the Boeotian form ἱός.[2][3]
  • 3rd century BC – Apollonius of Rhodes uses it for the first and second persons.[3][2]
