Forms

confirmar (first-person singular present confirmo, first-person singular preterite confirmé, past participle confirmado)[1] Medieval texts have the forms confirmo, confirmamos, confirmada, confirmolo and confirmé, among others.[2]

Etymology

It is borrowed from Latin cōnfirmō (“to strengthen; to establish, confirm”), a learned word.[3][4][5][6] The Latin verb is formed from con- and firmō (“to make firm”), from firmus (“firm, stable”).[7][8][1] Corominas treats it in the article on firme, which continues the same adjective and kept its ⟨f-⟩ because of its frequent use in legal and notarial language.[3]

The same learned verb is Portuguese confirmar, Catalan confirmar, French confirmer and Italian confermare.[9][10][11][1] In French the form confermer, common until the 16th century, gave way to the form remade on the Latin.[11]

The adjective goes back to *fermo- and *dʰer-mo- (“holding”), from the root *dʰer- (“to hold”).[12][1]

Earliest recorded meaning

The Breve diccionario dates the verb 1220–1250, the period of Berceo, and the Tentative Dictionary also starts with Berceo.[4][13] The DCECH's date of 1100, in the same article, belongs to the adjective firme.[3] The earliest hits of the CDH, from 1182 to 1218, are the subscriptions confirmo “I confirm” at the end of Latin charters, such as those of the monastery of Oña.[14] The first sense is “to make valid, ratify”: in Berceo's Milagros a case is por carta [...] confirmado “confirmed by charter”.[15]

Semantic evolution

The Siete Partidas of Alfonso X explain the word as “to make firm the thing that a man does or has done”.[15] The prose of Alfonso X already has the four main senses: to bear out the truth of something, to ratify what was approved, to give more firmness, and to administer the sacrament of confirmation.[16] Covarrubias defined it as “to revalidate what was done or said” and named the sacrament, in which the baptised are strengthened in the faith.[17] The Diccionario de Autoridades put “to approve anew” first and “to prove, corroborate” second.[18] From 1899 the Academy has given “to corroborate the truth” first, and its present dictionary adds a legal sense, the remedy of a curable defect in a contract.[19][5] In the Dominican Republic it also means “to give someone a mocking nickname”.[20]
