Etymology

Houaiss, Aurélio, the DLP and Wiktionary take it as formed from Portuguese validar + -ção.[2][3][4][1] Cunha instead dates it to the 17th century and calls it an adaptation of French validation, as he takes the verb validar from valider.[5] Houaiss records the noun in 1597, earlier than his first date for the verb, 1650.[2][6]

The verb comes from Late Latin validō (“to strengthen”), from validus (“strong”).[6][1]

Semantic evolution

The first sense is the act of making or declaring something valid;[2][7] Vieira (1871–1874) illustrates it with the validation of a marriage.[2][7] In law the word names the legitimation of an act that makes it legally effective, and in computing the test that checks data entered into a system against set rules.[2][8]

Timeline

  • 1597 – first record.[2]
  • 17th century – Cunha's date for the word.[5]
  • 1650 – the verb validar is recorded.[6]
  • 1813 – the form validição.[2]
  • 1871–1874 – Vieira defines it as the act of validating.[7]
