cumnat m (plural cumnați, feminine equivalent cumnată)[1]

Etymology

It is inherited from Latin cognātus (“related by birth, blood relative”), from con- and nātus (“born”).[2][3][4][5][1] The sense widened to “relative” and then narrowed in Vulgar Latin to “brother-in-law”, which all the Romance languages share.[2][6] Graur thinks the change came from words such as compater and consocer, used of relatives by marriage.[7]

The word survives in all four branches: Aromanian cumnat, Megleno-Romanian cumnat and Istro-Romanian cumnåt.[2][8][9][10] Its Romance cognates include Dalmatian comnut, Italian cognato, Occitan cunhat, Catalan cunyat, Spanish cuñado and Portuguese cunhado.[3][1] Albanian kunat is a loan from the same Latin word.[11][3]

Pușcariu saw a problem in the kept ⟨mn⟩, since the cluster was reduced in mioară;[7] Graur replies that the ⟨mn⟩ of those words was palatalised.[7]

Earliest recorded meaning

The first record is in a Wallachian charter of 1469.[2][4] MDA2's first record is Varlaam's Cazania of 1643.[5] The feminine cumnată is recorded from 1581, in a law code.[2]

Semantic evolution

The word names several in-law relations: the brother of one's husband or wife, the husband of one's sister, and the husband of the wife's sister.[2][6] The Banat has separate words for some of these.[6] At weddings, cumnat de mână is the second godfather who escorts the couple, and in Oltenia the cumnat carries the flask that invites the guests.[5][6] Ciorănescu derives the Bulgarian and Ruthenian words for “brother-in-law” from Romanian.[3]
