Forms

baixar (first-person singular present baixo, first-person singular preterite baixei, past participle baixado)[1] Houaiss records beyxar and bayxar in the 14th century, and the Cantigas de Santa Maria also have baxar.[2][3] Barbosa (1611) writes abaxar, and Feijó (1734) rejects the spelling baichar.[4][5]

Etymology

It is inherited from Vulgar Latin *bassiō (“to lower”), written Old Galician-Portuguese baixar in the oldest texts.[2][6][7][1] Houaiss and Cunha connect the verb with the Late Latin adjective bassus (“short and stout”), the source of baixo.[2][6] Machado compares the pair with *altiō, from altus (“high”), the source of alçar.[4] Wiktionary adds that the word can be analysed within Portuguese as a derivative of the adjective with the verb ending -ar, the derivation that Vieira and Figueiredo gave.[1][8][9]

The same Vulgar Latin verb is Galician baixar, Spanish bajar, Catalan baixar and French baisser.[1][10][11] The DHLF notes that the Romance languages set it against the verb for “to raise”.[11]

In the medieval glosses the Late Latin adjective means “fat, stout” and “short”.[12][13] Its origin is not known: Wiktionary lists a borrowing from Greek, from Oscan or from a Celtic language as possibilities.[1]

Earliest recorded meaning

Lorenzo's chronology moves Machado's 16th-century date back to the Cantigas de Santa Maria of the 13th century: baixaron a vea and a man who went about sempre baixada a testa “always with his head bowed”.[3] Cunha also dates the verb to the 13th century.[6] The figurative “to humble” is just as old: a cantiga has ca vimos melhores ca vós baixar “for we have seen better men than you brought low”, and the Crónica Troiana speaks of humbling the pride of enemies.[14][3]

Semantic evolution

The Crónica Troiana already uses the reflexive of the moon going down below the horizon.[3] Folqman (1755) gives “to come down from a place” and the ebbing of the tide.[15] Figueiredo (1899) records “to lose prestige” and the use of orders issued by the government, which still baixam to the offices below.[9][2]

In Brazil the verb took on several new senses: to be admitted to hospital, the descent of a spirit or orixá into a medium, and, in slang, to turn up somewhere.[2][1] In computing it translates English download.[16][2] In the Plate region of southern Brazil it also means to unsaddle a horse and to dismount.[17]

Timeline
