validar (first-person singular present valido, first-person singular preterite validei, past participle validado)[1]
Etymology
Houaiss, Aurélio and Wiktionary derive it directly from Latin: it is borrowed from Late Latin validō (“to strengthen”), from validus (“strong”).[2][3][1] Cunha and the DLP take it through French valider, from the Late Latin verb.[4][5] Cunha's first date is 1813, but Houaiss has a record of 1650.[4][2]
In Medieval Latin the verb meant “to reinforce, restore”, and Du Cange glosses it “to make valid” from a decree of the Parlement of 1394.[6][7] The Latin verb is formed from the adjective with the suffix -ō.[1] The Spanish word is validar.[8]
Earliest recorded meaning
Houaiss's first record is the Monarquia Lusitana of 1650.[2] Bluteau quotes the same work, vol. 5, for the sense “to make valid”: Instrumentos, com que validasse a sua pósse “documents with which he might make his possession valid”.[9]
Semantic evolution
The word has kept its legal sense, “to make a deed valid and lawful”: Morais (1789) illustrates it with a guardian's consent that validates a minor's promise.[10] Aurélio adds a computing sense, to carry out the validation of data.[3] A pronominal use, “to make oneself valued”, is recorded by Houaiss and Priberam.[2][11] Houaiss dates the nouns validação and validade to 1597, earlier than the verb.[12][13]
