Pronunciation
Forms
primeiro (feminine primeira, masculine plural primeiros, feminine plural primeiras)[1] Houaiss records prymeyro in the 13th century, primeira in the 14th, and primera and premeiros in the 15th.[2] Nascentes cites the archaic premeiro from Fernão de Oliveira's grammar;[3][4] premeiro is still a dialect form in Portugal.[3][4]
Etymology
It is inherited from Latin prīmārius (“of the first rank, chief”), written Old Galician-Portuguese prymeyro in the 13th century.[2][5][1] The Latin adjective is formed from prīmus (“first”) with the suffix -ārius.[6][1] Houaiss notes that this word, not the old Latin ordinal, became the Portuguese numeral, while the old ordinal lived on in primo with other senses.[2] The Wikcionário explains the ending by the movement of the /j/ of Latin ⟨-arium⟩ into the stressed syllable and the change of the resulting /ai/ to /ei/.[7] Nascentes regards the word as refashioned on the old form premeiro.[5]
The same Latin word is Galician primeiro, Spanish primero, Catalan primer and French premier; Italian primiero was taken from French.[8][1] García de Diego adds the Galician and Portuguese dialect forms Galician promeiro and Galician pirmeiro.[9] The learned primário and premiê, from French, are doublets of the same Latin word.[1]
Earliest recorded meaning
The Cantigas de Santa Maria already use the word as an adjective, as a noun and as an adverb: Esta é a primeira cantiga de loor de Santa Maria “This is the first song of praise of Holy Mary”, and andou primeiro França “first he went through France”.[10] The Miragres de Santiago say of the apostle James the Less foy o primeiro bispo que ouve en Iherusalem “he was the first bishop there was in Jerusalem”.[10] In a cantiga d'escarnho of Afonso X primeiro means “at first, before”.[10]
Semantic evolution
Houaiss dates both the numeral and the adverb “first, before anyone else” to the 13th century.[2] Bluteau in 1712 distinguished first in number or order from first in rank, giving primeyro em dignidade with Latin princeps.[11] Morais in 1789 added the sense “most eminent” and the construction primeiro de or primeiro que “before”.[12]
Modern Portuguese has the senses “best” (de primeira qualidade), “essential” (de primeira necessidade), “elementary” (primeiras letras) and “firstborn”, and as a noun “the winner”.[2][13][14] In informal Brazilian Portuguese de primeiro means “in the old days”.[2] Schlee's dictionary of Rio Grande do Sul refers the word to the local form primero.[15]
