Pronunciation

Forms

areoso (feminine areosa, masculine plural areosos, feminine plural areosas, metaphonic)[1]

Etymology

Houaiss takes it as a popular word, formed from Portuguese areia + -oso, a doublet of the learned arenoso.[2] The Academia's dictionary, Porto Editora, Michaelis and the Wikcionário also derive it from the noun with the suffix.[3][4][5][6] The noun itself continues Latin harēna (“sand”), whose adjective is harēnōsus (“sandy”).[7]

Nascentes, Aurélio and Vieira derive the word directly from the Latin adjective instead: Nascentes calls it a semi-learned outcome, and Aurélio and Vieira explain it by the loss of the nasal, the medial /n/ falling as it did in the noun for sand.[8][9][10] Cunha records both adjectives side by side from the 14th century.[11]

Earliest recorded meaning

Houaiss's earliest date, 1258, belongs to the place name Areosa in the Inquirições; the adjective “sandy” is dated by him and by Cunha to the 14th century.[2][11]

Semantic evolution

Bluteau sends areoso to areento and quotes the Monarchia Lusitana for terra areosa “sandy, loose soil”.[12] Morais (1789) quotes areoso deserto from the Cerco de Diu, and Vieira (1871) says the word belonged to the poetic language of the 17th century.[13][10] The old Aulete quotes Camões for as areosas covas deste rio.[14] Today it is a rare synonym of arenoso: Houaiss and Aurélio mark it as little used, and Porto Editora calls it less common than arenoso.[2][9][4]
