Pronunciation
Forms
confirmar (first-person singular present confirmo, first-person singular preterite confirmei, past participle confirmado)[1] Houaiss records cõfirmar in the 13th century and comffyrmar in 1292.[2] The Crónica Geral writes both confirmar and cõfirmar.[3]
Etymology
It is borrowed from Latin cōnfirmō (“to strengthen, consolidate, confirm”), by the learned route.[2][4][5][1] The Latin verb is formed con- + firmō (“to strengthen”), from firmus (“firm, stable”).[6][7][1]
The same Latin verb is Galician confirmar, Spanish confirmar, Catalan confirmar, French confirmer and Italian confermare.[8][7][1] In French the older confermer was replaced in the 16th century by the form remade on Latin.[7]
Earliest recorded meaning
Houaiss's first date is 1254, after Cunha's index of medieval Portuguese.[2] Lorenzo's record of that year is the charter formula roboro et confirmo et octorgo la carta.[3] A Latin charter of 983 already has the participle confirmada.[3] In a cantiga d'escarnho of Airas Perez Vuitoron someone fez mandado do Papa e confirmou-lh' o Esleito “did the Pope's bidding and confirmed the bishop-elect for him”.[3][9]
Semantic evolution
In Latin the verb first meant to strengthen the body or a thing, then to assure and to certify;[6][7] Christian writers made it a word of the liturgy.[6][7] Medieval Latin used it for confirming an earlier charter.[10] The medieval Portuguese texts have both senses: the Cantigas de Santa Maria say a cleric was na fe confirmado “strengthened in the faith”, and the Crónica Geral tells how a king confirmou a ley dos godos “confirmed the law of the Goths”.[3]
Morais (1813) defines it as to revalidate what is approved, to corroborate with new arguments, and as a synonym of chrismar “to confirm in the sacrament”.[11] Modern dictionaries add proving a hypothesis true and, in the reflexive, coming true; the sense “to make firmer” is now dated.[2][12][13]
