Forms

cunhado m (plural cunhados, feminine cunhada, feminine plural cunhadas)[1] Old Galician-Portuguese wrote cunado, cunnado, coynado and cuñado;[2][3] cunhado appears in the 14th century.[2][3]

Etymology

It is inherited from Latin cognātus (“blood relative”), written Old Galician-Portuguese cunado and Old Galician-Portuguese cunnado in the oldest texts.[2][4][1] In Latin the word meant a relative by blood, as opposed to affīnis, a relative by marriage; in Late Latin it took the sense of the brother of one's spouse.[2] Nascentes describes the change as going from a blood relative to a relative by marriage and finally to the brother of one's spouse.[5] In Medieval Latin the word was used for a wife's brother and for a sister's husband.[6]

The same Latin word is Galician cuñado, Spanish cuñado, Catalan cunyat, Occitan cunhat, Italian cognato and Romanian cumnat; in Romance its sense is everywhere that of the brother of a spouse.[7][2] The learned doublet is cognato.[1]

The Latin adjective is formed from con- (“together”) and nātus (“born”).[1][8]

Earliest recorded meaning

Latin charters write the word from the 10th century: Houaiss's first date, 938, is the Latin form cognata, and Lorenzo cites a charter of 985 with quod cognatus meus fecit “which my kinsman did”.[2][3] The first vernacular record in Lorenzo's chronology is a document of 1250: Joanes Fernandez, cunado de P. R. “Joanes Fernandez, brother-in-law of P. R.”.[3] The Cantigas de Santa Maria have the feminine ta cunnada “your sister-in-law”.[3]

Semantic evolution

In the 13th and 14th centuries the word could still mean any relative by marriage, though the modern sense was already taking over: the Galician Crónica General calls Ordoño the cunado of Diego González, although Ordoño was the cousin of Diego's wife.[9] Corominas describes the same narrowing in Spanish.[10] Pereira (1697) defines cunhado as the husband's brother, and Folqman (1755) as the brother of the husband or of the wife, adding meu cunhado for one's sister's husband.[11][12]

In Amazonia the word is used among the caboclos as a friendly form of address, “friend, mate”.[2][13] The word passed into Ambonese Malay as konyadu and into Nheengatu as kunhara.[1]
