Pronunciation

  • 5th-century BC Attic: /he.ky.rós/[1]
  • 4th-century AD Koine: /e.cyˈros/[1]
  • 10th-century Byzantine: /e.cyˈros/[1]

Forms

ἑκῠρός (hekurós) m (genitive ἑκῠροῦ); second declension[1] Inscriptions from Lydia have ὑκερός, with the vowels exchanged, and Daldis has ἱκερ-.[2][3]

Etymology

It is inherited from Proto-Indo-European *swéḱuros (“father-in-law”), an old kinship term kept in many languages.[4][1][2] Cognate with Sanskrit श्वशुर (śváśura), Avestan xvasura, Latin socer, Old High German swehur and Lithuanian šẽšuras, all meaning “father-in-law”.[4][2][5] The original initial consonant group with w still shows in Homer's metre, in the vocative of Iliad 3.172.[4][2]

The accent on the last syllable is a Greek innovation, after the feminine ἑκυρά (hekurá, “mother-in-law”) and perhaps πενθερός (pentherós).[4][2] The DGE treats the masculine as a thematic form made from the feminine.[3]

Byzantine scholars guessed at other origins: the Homeric Epimerisms derived it from δέχομαι (dékhomai, “to receive”) or from κυρέω (kuréō, “to meet”), because the father-in-law receives the bride, and Eustathius from the authority he holds over the family.[6]

Earliest recorded meaning

In the Iliad it is a husband's father, the father-in-law of a wife: Helen addresses Priam as φίλε ἑκυρέ, “dear father-in-law”.[3][7][8]

Semantic evolution

It remained an epic word; the ordinary word for a father-in-law was πενθερός (pentherós).[7] Corinna has the Boeotian verb ἑκουρεύω (hekoureúō), “to be father-in-law”.[2] In the Roman period Lydian inscriptions use it, in the plural, for both parents-in-law, and the emperor Julian uses it for Laertes as Penelope's father-in-law.[3]

  • Homer – The Iliad uses it for Priam as Helen's father-in-law.[3][7]
  • 5th century BC – Corinna uses the verb ἑκουρεύω, “to be father-in-law”.[2][3]
  • 1st–3rd century AD – Lydian inscriptions spell it ὑκερός and use the plural for both parents-in-law.[3]
  • 4th century AD – The emperor Julian uses it for Laertes.[3]
