Forms
ambos m pl (feminine plural ambas)[1] The feminine is ambas.[1][2] Houaiss records ambus and amos beside ambos in the 13th century, and medieval texts join the article to it as ambalas, ambolos.[2][3][4]
Etymology
It is inherited from Latin ambō (“both”), written Old Galician-Portuguese ambos in the oldest texts.[2][5][4][1] Cunha calls the Latin word an old dual.[5]
The same Latin word is Galician ambos and Spanish ambos.[6] Medieval Castilian usually had amos, and the form with /b/ spread from Leonese with the help of the Latin word.[7] There is also Italian ambedue.[6]
De Vaan reconstructs Proto-Italic *ambō and compares Ancient Greek ἄμφω (ámphō) and Lithuanian abù, and derives it from Proto-Indo-European *h₂(e)nt-bʰoH.[8] Wiktionary instead connects it with *h₂m̥bʰi (“round about”), though the Latin entry notes Dunkel's view that only the first syllable belongs to that root.[1]
Earliest recorded meaning
Machado quotes a Latin charter of 936 with inter ambas uillas “between both villages”.[4] In Galician-Portuguese the word is found from the 13th century; a document of 1228 has den ambos fiador “let both give a guarantor”, and the Cantigas de Santa Maria have Quando foron ambos a hũa parte “when both went to one side”.[5][3]
Semantic evolution
The medieval language often reinforced the word with the numeral: ambos e dous, ambos de dous, ambos a dous.[3][9] Morais in 1789 calls ambos de dous a faulty phrase, while Aurélio notes that the people still use ambos de dois;[10][11] Camões wrote De ambos de dous a fronte coroada.[10][11] Vieira insists that ambos is used only of two who do something at the same time.[12]
The forms with the article joined to the word, ambalas partes and in 1442 danbulos concelhos, gave way to ambos os, ambas as.[3][4]
