Forms

avô m (plural avôs, feminine avó, feminine plural avós)[1] Old Galician-Portuguese wrote avoo and auoo, and in the 14th and 15th centuries also abõo, aboo and auuo.[2][3][4]

Etymology

It is inherited from Vulgar Latin *aviolus (“grandfather”), written Old Galician-Portuguese avoo in the oldest texts.[2][4][5][1] Houaiss and Cunha explain the Vulgar Latin masculine as made from the feminine aviola, a diminutive of avia (“grandmother”).[2][4] Wiktionary and Priberam derive the diminutive directly from Latin avus (“grandfather”).[1][6] Machado traces it through the form that Latin charters of 1024 and 1132 write auolo, then the 13th-century spelling with a double vowel and the modern form in the 16th century: the loss of /l/ between vowels left two vowels in contact, which then merged.[5][7]

The same Vulgar Latin word is Galician avó, Spanish abuelo, Asturian güelu, Occitan aujòl and French aïeul.[8][1] The Meyer-Lübke dictionary notes that the Spanish and Portuguese forms, unlike the others, have lost the /i/ of the Latin word.[8]

The Latin word goes back to *awo- and to *h₂éwh₂os, a word for the grandfather on the mother's side, also continued in Old Irish and in the Latin avunculus (“maternal uncle”).[9][1]

Earliest recorded meaning

Latin charters of 1024 and 1132 already have the Romance form auolo.[5][2] In Galician-Portuguese the word appears in the 13th century: the Notícia de torto speaks of twelve farms given as dowry by a grandmother (sua auóó), and the Cantigas de Santa Maria have seu avoo “his grandfather” and the plural avoos in the sense “forefathers”.[5][3] The meaning was already “father of one's father or mother”.[3]

Semantic evolution

Cunha notes that the plural meant “ancestors” in the medieval language as it does today, and could also name the grandfather and grandmother together.[4] A charter of Noia of 1376 speaks of property de meus auoos, inherited from the forefathers.[3] Bluteau in 1712 explains the word with Latin avus and lists the terms for great-grandparents and earlier ancestors.[10] Feijó in 1734 distinguishes the singular avô with a closed vowel from the plural avós with an open one.[11]

The old Caldas Aulete records avô as a respectful title for an old man, and the DLP still labels this use popular and mostly rural.[12][13] Avô torto, literally “crooked grandfather”, is the father of a stepfather or stepmother.[2][13] The word passed into Mirandese abó, Nheengatu abú and Macanese avô-cong.[1]

Timeline

  • 1024 – a Latin charter writes auolo.[5][2]
  • 13th century – auóó in the Notícia de torto, and avoo and avoos in the Cantigas de Santa Maria.[5][3]
  • 1339 – meu auoo in a royal document.[5]
  • 1376 – meus auoos “my forefathers” in a charter of Noia;[3] aboo follows there in 1487.[3]
  • 16th century – Gil Vicente's Auto da Feira writes auo.[5]
  • 1712 – Bluteau's dictionary heads the word avô.[10]
  • 1734 – Feijó contrasts avô with the plural avós.[11]
  • 1899 – Figueiredo's dictionary records the reduplicated vô-vô, today vovô.[14]

Usage notes

The plural is avós when it means the grandfather and grandmother together, and avôs when it means only the two grandfathers.[12][15] Aurélio notes that avôs is now rarely used.[12][15] The feminine is avó, with an open vowel.[1][11] The phrase mais velho que o meu avô “older than my grandfather” means very old, or long known to everyone.[2][15]

Castro's vocabulary of the Mina-Jeje speech of 18th-century Ouro Preto records a separate word avô “clothing, cloth”, from a Fon word for cloth.[17]
