Pronunciation
Etymology
In Houaiss's view it is probably inherited from Latin iam magis (“already more”), a phrase made of iam (“now, already”) and magis (“more”), and it is written Old Galician-Portuguese jamais in the oldest texts.[2][3][4] Machado, as Houaiss reports, held that the adverb must go back to Vulgar Latin, since the other Romance languages have the same compound, and should not be explained as a Portuguese compound of já and mais; several dictionaries nevertheless explain it so.[2][5][6][7] Wiktionary instead derives it from the Old Occitan phrase ja mais.[1] Corominas suggested that Spanish jamás, recorded in Spanish from about 1140, was likewise a literary adaptation of the Occitan phrase, perhaps because of its use in lyric poetry, although Houaiss notes how early the Spanish word appears.[2][8]
The same phrase is Galician xamais, French jamais, Occitan jamai and Italian giammai.[1] In French the two old adverbs are recorded together from about 980 and were welded into one word in the 13th century.[9]
The first part is built on the pronoun stem of is (“he, that”): de Vaan explains it as an old accusative meaning “as far as this is concerned”, hence “now”.[10]
Earliest recorded meaning
Lorenzo's chronology gives as the first record a document of 1265 with the phrase por jamais “for ever”.[4] In the Cancioneiro da Ajuda the word means “never”, but also, without a negation, “from now on, always”, as in sempre ja mais.[4]
Semantic evolution
The positive sense of the early texts lived on in set phrases: the Miragres de Santiago have por senpre jamais and para senpre jamais “for ever and ever”.[4] In modern Portuguese the word is chiefly a negative, “never”, and with emphasis “under no condition”; in conditional clauses and after superlatives it still means “ever, at some time”.[2][11] Popular speech in Portugal also uses it for “above all, especially”, a sense Silva Bastos already recorded in 1912.[2][12][5] In southern Brazil the doubled nunca jamais strengthens the negation, as nunca jamás does in Uruguay and Argentina.[13]
