Pronunciation

  • /ˈsweɡɾo/, [ˈswe.ɣ̞ɾo][1]

Forms

suegro m (plural suegros, feminine suegra, feminine plural suegras)[1] Old Spanish also wrote sogro and sogra, socro and ssuegro.[2]

Etymology

It is inherited from Old Spanish suegro, inherited from Late Latin socrus (“father-in-law”).[1] The feminine suegra is socra (“mother-in-law”), which replaced classical socrus, a feminine of the fourth declension, because its ending marked it clearly as a woman's name.[3][4][5] The masculine did not come from classical socer (“father-in-law”): a masculine of the same form as the classical feminine, found in some glossaries, was made from the Vulgar Latin feminine, which was the more common word, since the mother-in-law played the larger part in family life.[3][4] The DLE derives the feminine from the Vulgar Latin form, and its 2001 edition the masculine from the classical one.[6][7]

The same pair is Portuguese sogro and sogra, Galician sogro, Asturian suegru, Catalan sogre and sogra, and Mozarabic xocro.[8][9][1] Italian suocero and some Italian dialects go back instead to longer Latin forms with the vowel kept before /r/.[3][10]

The Latin words continue *swekuros (“father-in-law”) and *swekrus (“mother-in-law”), from *swéḱuros and *sweḱrúh₂.[11][1] Their cognates include Ancient Greek ἑκυρός (hekurós, “father-in-law”) and Old High German swehur and swigar (“mother-in-law”).[11]

Earliest recorded meaning

Corominas dates suegra from a charter of 1156 in Oelschläger's list, which also has the half-Latin forms socra (1030) and sogra (1148); the masculine appears in charters of the 12th and 13th centuries.[3][4] The DEMel has sogro and sogra in documents from Nájera of 1124.[2] Alfonso X's Estoria de España (1270–1284) uses suegro of Caesar and Pompey, who were father-in-law and son-in-law.[12]

Semantic evolution

Nebrija in 1495 glossed suegro as the wife's father, and Percyvall in 1591 gave both socer and socrus.[13][14] The Diccionario de Autoridades treated the masculine and feminine together, as the dictionaries have done since.[15] The Academy's 1817 edition has a regional sense of suegra, the thin, well-baked ends where a ring of bread is joined, and the proverb suegra, ni aun de azúcar es buena, for the strife between mothers-in-law and their sons' and daughters' spouses.[16][17] In the Canary Islands suegra is also the pad worn on the head to carry loads, a sense taken from Portuguese sogra and added to the Academy's dictionary in 1970.[18]
