Pronunciation

  • Portugal: /ˈkoj.zɐ/[1]

Forms

coisa f (plural coisas)[1] The medieval form was cousa, also spelt coussa and quoussa in the 13th century;[1] coisa is first recorded in 1352 and coysa in the 16th century.[2][3][4] Houaiss now labels cousa informal.[2]

Etymology

It is inherited from Latin causa (“cause, reason; lawsuit; matter”), written Old Galician-Portuguese cousa in the oldest texts.[3][4][1] Houaiss explains the present form as the old one with the semivowel of the diphthong exchanged.[3]

The sense “thing” is Latin: the word was often used beside rēs (“thing, affair”) in legal language and took over its meaning.[3] In the spoken Latin of the 4th century it was already a synonym of the Latin noun.[5] Nascentes adds that it replaced the monosyllable because a word of one syllable had too little body, and that Hyginus and the Reichenau Glosses of the 8th century already use it so.[6][7] The learned causa, taken again from the same Latin word, is its doublet.[3][1]

The same Latin word is Galician cousa, Spanish cosa, Catalan cosa, Occitan causa, French chose and Italian cosa.[8][1]

Early inscriptions spell the Latin word caussa, which Wiktionary traces to Proto-Italic *kaussā.[9][1] Its further origin is unclear: Walde and Hofmann link it with cūdō (“to strike”), taking “a strike” as the first sense, while Ernout and Meillet doubt that it is Indo-European at all.[9]

Earliest recorded meaning

A Galician-Portuguese charter of 1228 has e todas aquelas cousas delle seyan do senor do Burgo “and let all those things of his belong to the lord of the Burgo”.[10] Charters of 1257 and later open with the formula Conozuda cousa seia “be it known”.[10] The Cantigas de Santa Maria speak of as cousas que á mester eno trobar “the things that making songs requires”.[10]

Semantic evolution

In the medieval texts the word covers objects, matters and events, and in the cantigas it can refer to a person.[10] With a negative it meant “nothing” (nulha cousa, cousa nenhuma), and a notarial book of Noia has cousa algũa “anything” in 1469.[10]

Cardoso's dictionary of 1569 renders Cousa with the Latin res.[11] Bluteau (1712) calls it the general name of everything in the world and derives it from Latin causa, quoting Hyginus's use of that word for a thing.[12] Morais (1789) records the saying não dizer cousa com cousa “to talk without sense or connection”.[13] Figueiredo (1899) heads the word Coisa and gives it the senses of reality, fact, business, mystery and, in the plural, property.[14]

In Brazil it serves as a vague word for anything one cannot or will not name, and in the north-east a coisa is slang for a cannabis cigarette.[1][15] The word passed into the Portuguese creoles: kusa in Kabuverdianu and Guinea-Bissau Creole, kousa in Papiamentu and cuza in Macanese.[1]
