Forms
decisão f (plural decisões)[1] Houaiss records the 16th-century spellings decysão and decizão (1550) and decissão (1559).[2] Pereira (1697) and Bluteau (1712–1728) head the word decisam, the spelling of their time.[3][4]
Etymology
It is a learned word, borrowed from Latin dēcīsiō (“a settlement; a decision”), the noun of the verb dēcīdō (“to cut off; to settle”).[5][6][1] Houaiss takes it from French décision, recorded in French in 1314, and that word in turn from the Latin noun.[2] Nascentes calls it a semi-learned word, and Wiktionary also allows a formation inside Portuguese, from Portuguese decidir + -são.[6][1]
In Latin the noun meant “a cutting down, a reduction” and, far more often, “a settlement, an agreement” of a dispute.[7][8] Medieval Latin used it for a judicial sentence.[9] The verb is formed from dē- and caedō (“to cut”).[5][10]
The same Latin noun gave Galician decisión, Spanish decisión, Catalan decisió, Italian decisione and Romanian decizie.[1][11]
Earliest recorded meaning
Houaiss dates the word to 1550, in the spellings decysão and decizão, with the sense “the act or result of deciding”.[2] Cunha's first record is from the 17th century.[5] Bluteau defines decisam as the final ruling that ends a lawsuit, a question or a doubt in business, and notes that the Latin word did not quite have this sense in Cicero.[4]
Semantic evolution
The word began in the language of the law and of disputes: a ruling or sentence that closes a case.[4][2] Morais (1813) gives the act of deciding and the sentence that settles a matter.[12] The 19th-century dictionaries add a sense of character, “resolve, courage”: Figueiredo lists coragem, intrepidez beside the legal senses.[10][13]
Modern dictionaries keep all three lines: a choice made after thought, a judge's ruling, and firmness in deciding.[2][14][15] Brazilian sport uses decisão for the deciding match of a championship, the final.[2][13]
