Pronunciation
Forms
convencer (first-person singular present convenço, first-person singular preterite convenci, past participle convencido)[1] The first record of 1369 is spelt conuencer.[2] Feijó (1734) gives convencer as the correct form, against convincer.[3]
Etymology
It is inherited from Latin convincō (“to overcome; to prove guilty”), recorded from 1369 as Old Galician-Portuguese conuencer.[2][4][1] Nascentes calls it a semi-learned word.[5] The Latin verb is formed from con- and vincō (“to conquer, win”).[6][1]
The same Latin word is Spanish convencer, Catalan convèncer, French convaincre, Italian convincere and Romanian convinge.[1][7] The French verb was taken from Latin about 1174 and reshaped after vaincre.[8]
De Vaan traces the Latin verb to a stem Proto-Italic *wink- (“to tie, bind”), which came to mean “tie in, overcome”, from a nasal present Proto-Indo-European *u̯i-n-k- (“to bend, tie”).[9]
Earliest recorded meaning
Houaiss dates the first record, spelt conuencer, to 1369, and Cunha places the verb in the 14th century with the sense “to persuade”.[2][4] The Horto do Esposo, in a copy of about 1390–1437, has one example.[10]
Semantic evolution
Barbosa (1611) glosses the verb with Latin convinco and Cicero's phrases on overcoming an opponent with authorities and witnesses, and Pereira (1697) adds confuto “to refute”.[11][12] Morais (1813) defines it as persuading with arguments that admit no answer, and convencer alguém de furto as proving a theft against someone so that he can say nothing in his defence.[13] Vieira quotes Francisco Rodrigues Lobo's Corte na Aldeia, where a go-between “persuades, advises and convinces like an orator”.[14]
The legal sense has faded, and modern Portuguese uses the verb for persuading someone or oneself, and, of a performance or a team, for winning over the audience.[2][15] Cunha dates the noun convencimento, in the spelling conujnzimento, to the 13th century, and the adjectives convencido and convincente to the 19th.[4]
