Forms
ambos m pl (feminine plural ambas)[1] Old Spanish usually had amos, amas, also written ammos, ammas, and less often ambos or anbos.[2][3] Dambos is found in Morisco texts and in Leonese today.[4]
Etymology
It is inherited from Latin ambōs (“both”).[4][5][6][1] The usual Old Spanish form was amos, the only truly Castilian one.[4][1] The form with ⟨b⟩ lived on beside it, first as a Leonese form, and then spread with the support of the Latin spelling.[4][1] Henríquez Ureña explains the Castilian form by the lengthening of the nasal before a voiced stop, /mb/ > /mm/ > /m/, as in the Cid.[7] The same word is Portuguese ambos, Galician ambos and Asturian amos, and the compounds Occitan ambedós and Catalan ambdós join it with the numeral “two”.[8][9][1]
The Latin word is an old dual, its ending ⟨-ō⟩ continuing the Indo-European dual ending.[10] It goes back to *ambō and is related to Ancient Greek ἄμφω (ámphō, “both”).[10][1] De Vaan reconstructs Proto-Indo-European *h₂(e)nt-bʰoH (“both”), perhaps a case form of *h₂ent- (“face, front”), as Jasanoff suggested.[10]
Earliest recorded meaning
Corominas dates the word to the Glosas Emilianenses of about 950.[4][5] The DEMel lists ambo in the Glosas Silenses (c. 950–1000) as a primary record.[2] In the Cantar de mio Cid it means “both” in amos los braços “both arms”.[11]
Semantic evolution
The phrase am(b)os a dos “both of them” is already in the Cid and Berceo.[4] Cuervo thought it an alteration of ambos dos, with a from dos a dos.[4] Schuchardt saw in it the Latin conjunction ac “and”, which fits the variant ambos y dos.[4] Corominas found ambos dos only from Santillana, but the TDHLE records it in the Fuero de Avilés about 1155, which supports Cuervo.[3] The compound entrambos occurs in Latin documents of 1031 and 1032.[4] In the 16th century Garcilaso and Juan de Valdés still wrote entramos, and Valdés judged it better than ambos.[4]
Covarrubias in 1611 called ambos a word relating to two things, and noted entrambos and entramos.[12] Autoridades called it a pure Latin word, and ambos a dos a pleonasm much used in Castilian.[13] Terreros made the same remark.[14] The Academy long classed it as a plural adjective, and the current dictionary classes it as an indefinite adjective and pronoun.[15][6] Ambos a dos is now literary.[6][16]
