Pronunciation

  • IPA (Classical): [kɔnˈjʊ.ɡi.ũː][1]
  • IPA (Ecclesiastical): [konˈjuː.d͡ʒi.um][1]

Forms

coniugium n (genitive coniugiī or coniugī); second declension[1] Inscriptions have coiugio.[2]

Etymology

It is from coniunx “spouse” or coniugō “to join”, with -ium, ultimately from con- and iungō “to join, yoke”.[2][3][1] De Vaan traces ⟨iungō⟩ to Proto-Indo-European *(H)yunégti (“yokes”), cognate with Sanskrit युनक्ति (yunákti, “yokes”) and Ancient Greek ζεύγνυμι (zeúgnumi, “to yoke”).[4]

Earliest recorded meaning

The OLD's earliest citation for marriage is Terence, and Accius has it of entering into marriage.[2] Köbler dates Terence 190–159 BC and Accius 170–c. 90 BC.[5]

Semantic evolution

It meant marriage, wedlock, as in Terence; the entering into marriage, as in Accius; by metonymy a spouse; and in Lucretius any close union, such as corporis atque animae “of body and soul”.[2][6]

In Ecclesiastical Latin it means union, marriage, wedlock.[7] British Medieval Latin used it with līberum for frank-marriage.[8]

Usage notes

Isidore of Seville derived it from the spouses being joined (coniūnctī), or from the yoke (iugum) by which they are coupled in marriage.[10]
