Forms

bairro m (plural bairros)[1] Old spellings include barrio (1301, in Trás-os-Montes), barrho (1321), bairro (1372) and bayrro (1611).[2][3] Cunha also records bairo and barro in the 14th century.[4]

Etymology

Houaiss calls its origin disputed.[3] Houaiss, Cunha, Corominas and the DLE take it from a colloquial Andalusian Arabic word for “outside, exterior”, which in the classical language is borrowed from Arabic بَرِيّ (bariyy, “wild”).[3][4][2][5][1] Corominas starts from the Arabic word for the outskirts of a town, or more precisely from its derivative meaning “exterior”.[2] Wiktionary explains the sense from the outlying, less urbanised parts of a town.[1] Houaiss has the word pass through Late Latin barrium, which a Latin document of Zamora already uses in 949.[3][2]

Houaiss also gives a second explanation: a noun Vulgar Latin *barra (“crossbar, partition”), with an adjective *barriu- “lying outside”, from which the Portuguese and Spanish words would come.[3] He notes that the sense “part of a town” is later than “outskirts, suburb”.[3]

The diphthong goes back to the older Old Galician-Portuguese barrio, with the /j/ of the ending drawn into the stressed syllable, a change Vieira called regular.[6][1]

The same word is Spanish barrio, Catalan barri and Old Occitan barri, the Occitan form recorded from the 12th century in Bertran de Born.[2] It passed into Basque barrio “yard, farmyard”.[2]

Earliest recorded meaning

Houaiss's first date, 968, is a charter of the Portugaliae Monumenta Historica, the collection of Latin documents, where the word appears as barra.[3] The first Portuguese record Corominas cites is barrio in a document of 1301 from Trás-os-Montes.[2] In 1372 bairro meant a settlement next to a town.[3] Corominas finds the same first sense, a hamlet dependent on a town, in the oldest Spanish documents.[2]

Semantic evolution

From a settlement outside a town the word came to mean a suburb, and then a quarter inside the town: Houaiss dates the sense “part of a town” to 1611.[3] In Spanish Corominas traces the same path, while in Occitan and Catalan the word went from the suburb to the wall around it and then to a fence or enclosure.[2] Medieval Latin barrium already meant both a rampart and a suburb.[7]

Bluteau defines it as a part of a town with its houses and streets, and notes that around Santarém it meant the same as monte.[8] Vieira describes Lisbon as divided into four bairros: Alfama, Rocio, Alto and Alcântara.[6] The old Caldas Aulete records the administrative bairros of Lisbon and Porto, each headed by an administrador de bairro, and a sense “village, hamlet” in Minas Gerais.[9] The derivatives bairrista and bairrismo, for a person attached to his own quarter, date from the 19th and 20th centuries.[4] In Mozambique bairro names a periurban settlement of shacks.[10]
