Forms

baixo (feminine baixa, masculine plural baixos, feminine plural baixas)[1] The medieval spellings were baixo and bayxo;[2][3][4] baxo appears from the 15th century and is still the headword of Vieira's dictionary in 1871.[2][3][4]

Etymology

It is inherited from Late Latin bassus (“stout, low”), written Old Galician-Portuguese baixo and Old Galician-Portuguese bayxo in the oldest texts.[2][5][3][1] The Latin adjective is known only from glosses and as a personal name: the St Gall glosses of the 8th century explain it as “fat, not tall”, and Medieval Latin has it for “stout”, “short” and “low”.[3][6] Machado, after Ernout and Meillet, thinks it may be of Oscan origin, like the family names Bassus and Bassius borne by Campanians;[3][1] Wiktionary also mentions a borrowing from Greek or from a Celtic language.[3][1]

The same word is Galician baixo, Spanish bajo, Catalan baix, French bas and Italian basso.[7][8][1]

The ⟨ix⟩ of the Portuguese word, like the ⟨j⟩ of the Spanish word, is not the regular outcome of Latin /ss/.[9][10] Corominas and Aurélio explain it by the influence of the verb baixar, from Vulgar Latin *bassiare.[9][11][12] Nascentes, after Meyer-Lübke, even derives the adjective from the verb, unless one accepts with Diez a special development of ⟨ss⟩;[10][4] Vieira in 1871 had taken the change for a normal one.[10][4]

Earliest recorded meaning

A 13th-century Latin record of the royal inquiries already has the Romance feminine: in villa bayxa.[3] In the Crónica Troiana the adjective means “low” in place (do lugar mais alto vijnr a agoa ao mais bayxo “the water comes from the highest place to the lowest”), “soft” of the voice, “of humble lineage”, and “on foot, dismounted”.[13]

Semantic evolution

The figurative senses “humble, lowly” and “soft (of a voice)” are medieval.[13] As a noun, baixo “sandbank, shoal” appears in 15th-century texts on the voyages of discovery, as in naves that were lost em huns baixos;[3] Italian basso has the same sense in a dictionary of the navy of 1504.[3] Houaiss dates baixos “the lower rooms of a house” to 1712.[2] Folqman (1755) records voz baixa “a quiet voice” and estilo baixo “a plain, unelevated style”.[14]

In music the noun names the lowest male voice and its singer, the lowest melodic line of a piece and the lowest note of a chord.[2][15] The instrument called baixo is a shortening of contrabaixo, itself borrowed from Italian, the double bass and later the bass guitar, and by extension the person who plays it.[16][1]

Brazilian Portuguese has the informal noun “a gaffe”, and in the north and north-east of Brazil baixo is a comfortable gait of a saddle horse; in Ceará the adjective means “incapable”.[2][17]
