Forms

longo (feminine longa, masculine plural longos, feminine plural longas)[1] Old Galician-Portuguese wrote longo and longu in the 13th century, lõguos in the 14th and llonga in the 15th.[2]

Etymology

It is inherited from Latin longus (“long”), written Old Galician-Portuguese longo in the oldest texts.[2][3][1][4] Beside it, the Latin adverb longē gave the Portuguese adverb meaning “far”.[3]

The same Latin word is Galician longo, Spanish luengo, Catalan llong, French long, Italian lungo and Romanian lung.[5][6] The Spanish word was in general use throughout the Middle Ages but became old-fashioned in the 16th century, giving way to largo.[7]

De Vaan reconstructs Proto-Italic *(d)longo- and PIE *dlongʰ-o-, the form that also underlies lang and langr; other branches point to *dl̥h₁gʰós, as in ìlgas, and he leaves open whether these variants were once one word.[8] Wiktionary derives the Latin word from that second form, and compares *langaz.[1]

Earliest recorded meaning

A Latin charter of 897 names a church de sancto martino de ualongo, with the word in a place name.[9][2] In the vernacular the adjective is recorded from the 13th century: the Cancioneiro da Ajuda has longa sazon “a long time”, and the Crónica Troiana uses it of long hair (os cabelos boos et longos), of a story too long to tell and of a far country (moy longa terra).[9][3]

Semantic evolution

The cantigas already use the word in its three senses, “long” in space, “stretching far” and “lasting”, and also as an adverb “for a long time”.[10][11] Bluteau (1712–1728) cites Camões's tão longo amor and gives the term of prosody syllaba longa “long syllable”.[12] Folqman (1755) records ao longo do mar “along the coast”, and Morais (1789) the senses “extended” and, figuratively, “lasting a long time”, as in longo tempo.[13][14]

Modern Portuguese adds the noun senses “length” and “long dress”, and an adverb “for a long time”.[2] In Galician the word also means “tall”.[15]
