Forms

uso m (plural usos)[1] Houaiss records the 13th-century spellings uso and vso and a 15th-century usu.[2] Wiktionary lists usso as an alternative form.[1]

Etymology

It is inherited from Latin ūsus (“use, practice, experience”), written Old Galician-Portuguese uso in the oldest texts.[2][3][1] Houaiss also notes usage (“use”) in the 13th century, a borrowing of the Romance noun that is French usage.[2][4]

The same Latin word is Galician uso, Spanish uso, Catalan ús, French us and Italian uso.[4][5][1]

The Latin noun is the action noun of ūtor (“to use”), from *oitōr;[6][7][1] Wiktionary considers a link with Proto-Indo-European *h₃eyt- (“to take along, fetch”) possible.[6][7][1]

Earliest recorded meaning

Lorenzo's first record is in the Cantigas de Santa Maria, como é de caer uso, and a document of 1310 has como e vsso da terra “as is the custom of the land”.[8] The cantigas also use aver d'uso “to be in the habit of”: Estevan da Guarda writes Sempr' esto ouvemos d'uso, eu e mia madre “my mother and I always had this habit”.[8][9] The first sense was thus “custom, habit”.[8]

Semantic evolution

Medieval texts pair uso with custume, and a charter of 1328 lists priuilegyos usos libertades “privileges, customs, liberties”.[8] Bluteau (1712–1728) distinguishes use, “employing a thing for what it was made for”, from custom.[10] Folqman (1755) records the legal sense, the right to use a thing one does not own.[11]

Vieira (1871–1874) gives a commercial sense, the term (usually 30 days) allowed for paying a bill of exchange.[12] Modern dictionaries add fashion, wear, and the use of words in a language; in rural Portugal the plural usos were the clothes given to farm servants on top of their wages.[13][14][1]
