Pronunciation

  • Brazil: /ˈso.ɡɾu/[1]
  • Portugal: /ˈso.ɡɾu/, [ˈso.ɣɾu][1]
  • Portugal, Southern: /ˈso.ɡɾu/[1]

Forms

sogro m (plural sogros, feminine sogra, feminine plural sogras, metaphonic)[1] The feminine sogra has an open /ɔ/, while the masculine singular and plural have a closed /o/.[1][2] The 14th century also wrote ssogro.[3][4]

Etymology

Its origin is disputed.[3] Houaiss reports the view of Cunha and Machado that it is a formation from Portuguese sogra (“mother-in-law”), and notes that the dates do not contradict it: the feminine is recorded long before the masculine.[3] The Aurélio holds the same view, explaining it by the great part the mother-in-law played in family life.[5] The feminine continues socra, which replaced classical Latin socrus (“mother-in-law”).[6][4]

Others take the masculine straight from Latin.[4][1][7] Nascentes derives it from *socru, a syncopated form of the accusative of Latin socer (“father-in-law”), current after the word for “mother-in-law” had changed its form.[7][3] The DDGM and Wiktionary derive it from a masculine that Late Latin made on the model of the feminine, and Wiktionary notes that this masculine is attested in late glosses and inscriptions from North Africa.[4][1] The REW lists the Portuguese word among the Romance words from these late forms.[8]

The same late forms gave Galician sogro, Spanish suegro, Catalan sogre, Occitan sògre and Romanian socru.[8][1] The Latin word goes back to Proto-Italic *swekuros and Proto-Indo-European *swéḱuros (“father-in-law”), the source also of Ancient Greek ἑκυρός (hekurós, “father-in-law”), while the word for “mother-in-law” continues the feminine *sweḱrúh₂ (“mother-in-law”).[9][1]

Earliest recorded meaning

The feminine appears first, inside Latin charters: de parte de mea sogra “on my mother-in-law's side” in 1094, and mea socra Aragunti in 1108.[4][3] A charter of 1113 has the masculine in Latin dress, quod fuit de socrum meum “which belonged to my father-in-law”.[4][3] In Galician-Portuguese texts the masculine is found in the 14th century: the Crónica de 1344 has seu sogro “his father-in-law”, and the Miragres de Santiago despois da morte do sogro “after the death of the father-in-law”.[4][4]

Semantic evolution

The meaning has not changed: the father of one's husband or wife, as Cardoso already glosses it with Latin socer.[10][3] The plural sogros also names the couple, father- and mother-in-law together.[3][11] Bluteau collects several proverbs about the father-in-law, such as Estende-se como villão em casa de seu sogro “he sprawls like a peasant in his father-in-law's house”.[12]
