From the same root
Pronunciation
- /afiɾˈmaɾ/, [a.fiɾˈmaɾ][1]
Forms
afirmar (first-person singular present afirmo, first-person singular preterite afirmé, past participle afirmado)[1] Old forms include affirmar and afyrmar; a popular ahirmar is found in texts of the 16th and 17th centuries.[2][3]
Etymology
It is borrowed from Latin affirmō (“to strengthen, confirm; to assert”).[3][4][5][1] Corominas adds that in some senses it is a popular formation from firme, and the 1726 Autoridades already analysed it as a- with the adjective.[3][6] The Latin verb is formed ad- (“to”) and firmō (“to strengthen”), from firmus (“firm”).[7][1]
García de Diego calls the standard form a learned word and sets beside it the popular outcome: Old Spanish ahirmar and similar Cantabrian forms.[8][9] The Academy recorded this variant from 1726 as rare or old, between 1770 and 1817 as used only in carpentry and other trades.[2] The same Latin word is Portuguese afirmar, Catalan afirmar, French affirmer and Italian affermare.[9][1]
Earliest recorded meaning
Corominas dates the word to Berceo (1220–1250).[3][4] The TDHLE quotes an earlier affirmot “confirmed” in a charter of 1062 from San Juan de la Peña, and afirmare in the Fuero de Medinaceli of about 1129, both in the sense “to confirm, ratify” of legal documents.[2] The Fuero de Zorita (1218–1250) has tod aquel que afirmar ouiere, of a man who has to establish a claim.[10]
Semantic evolution
The oldest sense is “to confirm, ratify”, especially in notarial use; from it come “to make firm, steady” and, by the 13th century, “to state as true”.[2][11] Alfonso X's prose already has the verb for fixing an instrument in place, for asserting something, and reflexively for keeping to what one has said.[11] The Autoridades of 1726 also recorded an Aragonese sense “to settle, reside” and Covarrubias a fencing term, afirmarse “to advance firmly on the opponent with the point of the sword”.[6][12] Cervantes writes that Don Quixote se afirmó bien en los estribos “planted himself firmly in the stirrups”.[13]
In Chile and Mexico afirmar has meant “to deal (blows)”, a sense that Román criticised and the dictionaries of Americanisms record; in the Canaries it means to give someone a thrashing.[14][15][16][17] In Judeo-Spanish it means “to sign”, and afirmarse is said of a prophecy or a blessing that comes true.[18]
