Forms

declaração f (plural declarações)[1] Medieval texts write decrraraçom (1339), declaraçom, declaraçon (14th century) and decreraçam (15th century).[2][3]

Etymology

It is borrowed from Latin dēclārātiō (“a making known, disclosure”), a learned word.[3][1][4][5] Nascentes calls it semi-learned, and Houaiss analyses it as a Portuguese formation, from Portuguese declarar + -ção;[6][2][1] Wiktionary gives that analysis too, beside the Latin source.[6][2][1] The Latin noun is formed from dēclārō (“to make known, declare”), which is dē- and clārō (“to make clear”).[7][1]

Other Romance languages have the same learned word: Galician declaración, Spanish declaración, Catalan declaració, French déclaration and Italian dichiarazione.[1][8]

Earliest recorded meaning

Houaiss's first record is decrraraçom in a text of 1339 from Cunha's index of medieval Portuguese.[2] A notarial book of Noia in Galicia, in 1412, uses declaraçón for the sworn statement that witnesses make before the notary.[9] The Horto do Esposo (witness 1390–1437) writes declaraçom.[10]

Semantic evolution

In the 16th and 17th centuries the dictionaries render it with Latin words for “explanation, interpretation”: Cardoso's interpretatio and expositio, Barbosa's explicatio and declaratio.[11][12] Morais (1789) lists “explanation”, the declaration of war, the declaration of one's goods to the authorities, and testimony.[13] Vieira adds the document by which something is declared.[14] The modern dictionaries add the declaration of love.[15][2] In tax use declaração de renda is the return of one's income.[2]
