Ultimate origin
Latin (nūbō)

Pronunciation

  • IPA (Classical): [koːˈnuː.bi.ũː], [koːˈnʊ.bi.ũː][1]
  • IPA (Ecclesiastical): [koˈnuː.bi.um][1]

Forms

cōnū̆bium n (genitive cōnū̆biī or cōnū̆bī); second declension[1] Less correctly connūbium;[2] the ū is certainly long in Catullus, Ovid and Seneca, but in Lucretius and Virgil it can be read short, and poets often scan the word in three syllables.[3][2]

Etymology

It is from con- and nūbō “to marry” with the suffix -ium.[3][1] De Vaan explains the long ⟨cō-⟩ from earlier ⟨*com-sn-⟩, and Weiss reconstructs ⟨*kon-snoubiom⟩; de Vaan finds the origin of ⟨nūbō⟩ itself unclear.[1][4] Isidore derived it from ⟨nūbere⟩, not from ⟨nūpta⟩.[5]

Earliest recorded meaning

The OLD's earliest citation for marriage between two persons is from Catullus.[3] Köbler dates Catullus 81/79–52/50 BC.[6]

Semantic evolution

It was intermarriage between two peoples or groups, and in law the right to intermarry, as in Livy; and marriage between two persons, the right to marry, as in Catullus and Virgil.[3][2] Isidore explains that cōnūbium is said when equals, such as Roman citizens of the same rank, marry.[5]

In Ecclesiastical Latin it meant marriage.[7] British Medieval Latin used it for a wedding, marriage, and a nun's espousal to Christ.[8] It was borrowed into Italian as connubio.[1]
