Etymology

It is inherited from Latin sāl (“salt”), written Old Galician-Portuguese sal in the oldest texts.[2][3][1] Old spellings include Old Galician-Portuguese sall (1391) and Old Galician-Portuguese ssal (1392).[2] The word kept the masculine gender of Latin, as in Italian and French.[2] Spanish made it feminine, as did Catalan, much of Occitan and northern Italy, perhaps through the neuter that some archaic and late Latin authors give it.[2][4][5] Galician-Portuguese has the masculine from the cantigas of Alfonso X on.[4]

The same Latin word is Galician sal, Spanish sal, Catalan sal, French sel, Italian sale and Romanian sare.[5][1]

The Latin noun goes back to Proto-Italic *sāls, with a long vowel in the nominative and a short one in the other cases, which de Vaan traces to an ablauting Proto-Indo-European *sē̆h₂-l-s.[6][1] Its cognates include Ancient Greek ἅλς (háls), Old Irish salann and Old English sealt, the ancestor of the English word salt.[1][6] Houaiss also names *saltom, the source of the English word and of Salz.[2] Bluteau in 1712 took the Portuguese word for the Greek word with its letters transposed.[7]

Earliest recorded meaning

A Latin charter of 1008 already has et IIIIor modios de sal “and four measures of salt”.[8][2] In Galician-Portuguese the word is recorded from the 13th century.[3] The Cantigas de Santa Maria speak of eating field greens sen sal “without salt”, and use the simile of water dissolving salt, como desfaz agua sal, for something brought to nothing.[8]

Semantic evolution

The Latin noun already had the figurative sense “wit”, and the plural meant “jokes”.[9] Portuguese has the figurative sense too: a person or story sem sal is dull, and sal is the grace or piquant malice of what is said or written.[2][10] The Ordenações Afonsinas regulate the buying of fruit, wine and salt in the Algarve.[11]

Chemistry gave it the general sense of a compound formed from an acid and a base, which Houaiss puts first.[2][12] By metonymy it can mean the water of the sea, and the plural sais means smelling salts, given to revive someone who has fainted, or bath salts.[2][13] Feijó (1734) records the plural spelling saes.[14] Set phrases include sal ático “Attic salt”, a refined and witty style, and sal-gema “rock salt”.[2][15] The Gospel phrase o sal da terra “the salt of the earth” is the name Jesus gave the apostles.[16]

Usage notes

In the medieval cantigas sal is also a form of the verb sair “to go out”, as in Martim Padrozelos's vem, e sal-m'este coraçom.[19][8] Viterbo records the same form in a document of 1292 with the sense “to leave this world, to die”.[20] Wiktionary also has a rare noun sal for the sal tree, Shorea robusta.[1]
