boca f (plural bocas)[1] Old Spanish texts also write bocca, voca and boqua.[2][3][4]

Etymology

It continues inherited from Old Spanish boca, inherited from Latin bucca (“cheek; mouth”).[5][6][7][1] The original sense “cheek” survives on the edges of the Romance area: Romanian bucă still means “cheek”, as do the words that Modern Greek, Berber, Breton and Welsh borrowed from Latin.[5] The sense “mouth” is rarer in Latin but already found in Cicero, and it won out in almost all the Romance languages.[5] It replaced Latin ōs, which probably did not survive because it was a single short syllable.[8]

The same Latin word is Portuguese boca, Galician boca, Asturian boca, Catalan boca, French bouche and Italian bocca.[9][10][1]

According to de Vaan, the Latin word first meant a puffed, filled-out cheek;[11] “mouth” is a later sense and was at first derogatory.[11] The DLE calls it Celtic and compares Gaulish bocca.[7] Ernout and Meillet, as de Vaan reports, suspected a Celtic origin because the word resembles beccus (“beak”) and the Celtic personal names Buccus and Buccō.[7][11] De Vaan leaves the question open and notes that the Germanic comparisons, if right, would point to a non-Indo-European source.[11]

Earliest recorded meaning

Corominas's first record is the Cantar de mio Cid (c. 1140, in a 14th-century copy): the weeping townspeople „de las sus bocas todos dizían una razón” “all said with one voice”.[5][12] The DEMel lists an earlier primary record, boca in a charter of 1116 from the Oña collection.[2] The Fuero de Zorita de los Canes (1218–c. 1250) is the first text with no later copy.[12]

Semantic evolution

In the Cid the mouth already stands for what one says.[13] In a challenge to a duel, „por tu boca lo dirás que eres traydor” “you will say with your own mouth that you are a traitor”, the mouth stands for the confession itself.[13] Menéndez Pidal cites the fueros of Oviedo and Avilés, where a man taking back an insult had to put his finger through his teeth.[13] Old Spanish also used the word for an animal's mouth, for an entrance and, in a boca de noche, for nightfall.[3] Alfonso X's prose has the mouth of a furnace and of a jar and the mouth as the organ of speech.[14]

Covarrubias in 1611 records many phrases, among them a boca llena, which he uses to render a line of Horace, and quitarse algo de la boca “to go without something in order to give it to another”.[15] The Diccionario de Autoridades adds a large opening such as the mouth of a cave.[16] It also has bocas as an Andalusian name for a small crab-like crustacean.[16] The Academy's dictionary of 1817 has the claws of crabs, the cutting edge of tools, the taste of a wine and a person one must feed.[17] The 1869 edition adds the mouths of rivers.[18] In Central America boca is a snack served with drinks.[19]
