Pronunciation

  • Brazil: /ˈbo.kɐ/[1]
  • Portugal: /ˈbo.kɐ/[1]

Forms

boca f (plural bocas)[1] Houaiss records boquua from the 14th century and bocha from the 15th;[2][3] Silva Bastos still gives bocca as a variant in 1912.[2][3]

Etymology

It is inherited from Latin bucca (“cheek; mouth”), written Old Galician-Portuguese boca in the oldest texts.[2][4][5][1] The same Latin word is Galician boca, Spanish boca, Catalan boca, French bouche, Italian bocca and Romanian bucă.[6][1]

The first sense of the Latin noun was the puffed-out cheek, and “mouth” was a familiar, at first rather contemptuous, use beside the ordinary word ōs.[7][8][5] Corominas notes that “mouth”, though the rarer sense in Latin, is the one that won in nearly all the Romance languages, from Dalmatian to Portuguese, while the sense “cheek” survives in Romanian and in the Latin loans of Breton and Welsh.[9] Nascentes points out that Cicero had already used the word for “mouth”.[10]

The origin of the Latin word is not settled: Wiktionary and the DLE call it Celtic, comparing boc(c)a.[1][11] De Vaan reports that Ernout and Meillet suspected a Celtic origin because the word resembles beccus (“beak”) and Celtic personal names such as Buccus, and he himself sees it as one of the abusive words in which Latin often doubles a consonant.[7] The OLD calls it imitative.[8]

Earliest recorded meaning

Machado and the DDGM quote a Latin charter of 1085 in which the Romance word already appears: usque ad bocca de carreira antiqua “as far as the mouth of the old road”, in the sense of an opening or entrance.[5][12] Houaiss dates that sense to 1085 and the sense “mouth” to the 13th century.[2] In Galician-Portuguese the Cantigas de Santa Maria tell how Mary made a flower grow na boca of a cleric, and a cantiga d'escarnho has che tapo eu daquesta minha / boca a ta boca “I stop your mouth with this mouth of mine”.[12]

Semantic evolution

From the mouth of a body the word spread early to openings of all kinds: the 1085 charter already uses it for the opening of a road.[2][5] Barbosa's dictionary of 1611 has boca do rio for the mouth of a river, boca de forno for the mouth of an oven and boca da noyte for nightfall, and Morais in 1789 adds boca for a person to be fed, the mouth of a cannon and bocas de fogo “firearms”.[13][14] Houaiss dates the sense “notch in a blade” to 1789.[2]

Brazilian, African and Mozambican Portuguese use boca for the burner of a gas stove.[2] In Brazil it also came to mean an opportunity or a job, and in criminal slang a place where drugs are sold (boca de fumo); in Portugal a boca is a taunting or provocative remark.[2][1] The word passed into Kabuverdianu as bóka and into Guinea-Bissau Creole and Kristang as boka.[1]
