Etymology

It is a learned word, borrowed from Latin affirmātiō (“strengthening; positive statement”), first recorded in the early 15th century.[2][1][3] The BDELC treats it under firme, beside the verb afirmar, which it dates to 1220–1250 and derives from the Latin verb behind the noun.[4] This verb meant properly “to make firm”.[4]

The Latin noun is formed from affirmō (“to strengthen, assert”) with the suffix -tiō.[5][1] The verb is made of ad- (“to, towards”) and firmō (“to strengthen”), from firmus (“firm, strong”).[1][6] The same Latin word gave Portuguese afirmação, French affirmation and Italian affermazione.[1][7]

Earliest recorded meaning

The CDH's earliest hit is in a Castilian Bible translation of about 1400, where it is said that a king's promise and afirmaçion must not be set aside.[3] Pero López de Ayala's Caída de príncipes (1402) and the Castilian translation of Maimonides' Guide of the Perplexed (1419–1432) use it for an assertion or a positive statement.[3] DICCA-XV dates its first record to 1430–1460, and Alonso's dictionary to the 15th century.[8][9]

Semantic evolution

In 15th-century texts the word is already the act of asserting something as true, and an oath is defined as a religious afirmación.[3] In logic and grammar it was set against negación: Palencia's vocabulary of 1490 divides a proposition into affirmation and negation.[10] Barcia's dictionary of the 1880s records an obsolete legal acta de afirmación, a sworn assurance given to a judge.[11] The modern Academy dictionary gives the act and effect of affirming, and Moliner adds the words with which one affirms.[2][12]
