Pronunciation

  • IPA (Classical): [kɔŋˈnaː.tʊs][1]
  • IPA (Ecclesiastical): [koɲˈɲaː.tus][1]

Forms

cognātus (feminine cognāta, neuter cognātum); first/second-declension adjective[1]

Etymology

It is from Latin con- + gnātus (“born”), gnātus being the old form of nātus, the participle of nāscor “to be born”.[2][3][4] Gnātus continues Proto-Italic *gnātos, from Proto-Indo-European *ǵn̥h₁tós, from Proto-Indo-European *ǵenh₁- (“to beget”).[1]

Earliest recorded meaning

Köbler's first source for the noun is Plautus, and Terence uses it of a woman who is a close relation.[5][2] Köbler dates Plautus about 250–184 BC.[5]

Semantic evolution

It meant related by birth, and as a noun a blood relation on either the father's or the mother's side, a wider term than agnatus, which was a relation in the male line.[2][6][4] It also meant belonging to kinsmen, as Catullus' line about a grave not laid near kindred ashes, and Virgil's kindred cities.[2][7] Figuratively it meant akin or having affinity, as in Cicero's Timaeus and of words fitting the things they name.[2]

The Vulgate uses cognati of fellow members of a people, as Paul of the Israelites, his kinsmen according to the flesh.[3] Medieval Latin used it of relations by marriage, a brother-in-law, nephew or cousin.[8][9][5] It survives in Spanish cuñado and Portuguese cunhado “brother-in-law” and Romanian cumnat.[1] English cognate is recorded in the 1640s, first of people related by birth.[10]
