Pronunciation
Forms
afirmar (first-person singular present afirmo, first-person singular preterite afirmei, past participle afirmado)[1] Old texts write afirmar and affirmar (14th century) and afyrmar (15th).[2] The etymological spelling affirmar lasted until the 20th-century reforms;[3][1] Figueiredo (1899) enters afirmar as the same word as affirmar.[3][1]
Etymology
It is borrowed from Latin affirmō (“to strengthen; to assert”), a learned word.[2][4][5][1] Nascentes calls it semi-learned, and the glossary of the Crónica Geral a learned derivative.[6][7] The Latin verb is formed from ad- and firmō (“to strengthen, make firm”), from the adjective firmus (“firm”).[8][1][9]
The same Latin verb is Italian affermare, Old French afermer and Old Occitan afermar; in Spanish the inherited form was Old Spanish ahirmar, and Spanish afirmar is learned like the Portuguese word.[10][11] The old form was remade in the 13th century as French affirmer.[9]
Earliest recorded meaning
Houaiss dates the first record to the 14th century, from Cunha's index of medieval Portuguese.[2] Machado quotes a 14th-century text: e quando el viu que lho afirmavam de verdade “and when he saw that they assured him of it as the truth”.[5] The Crónica Troiana has it both for asserting (el afirmou que aynda auya de uijr tal sazon “he affirmed that a time would yet come”) and for confirming agreements.[7]
Semantic evolution
The Crónica Geral shows the range of the medieval verb: to confirm a law, to prove, to assure, to settle a pact firmly, and even to come to an end.[7] Cunha dates the word to the 16th century, with both senses “to make firm” and “to state firmly”.[4] Cardoso (1569) and Barbosa (1611) render it with Latin assevero and affirmo.[12][13]
Vieira (1871–1874) records the physical sense “to fix, to steady” and the reflexive afirmar-se “to hold oneself firm”.[14] The DLP now marks “to make firm” as obsolete.[15] From the reflexive came “to assert oneself, to become established”, and the physical sense gave afirmar a vista “to fix one's gaze”; in northern Portugal afirmar-se means to look closely.[2][16][17][18] Michaelis records a hunting sense: to train a dog to follow only one kind of game.[19]
