Forms

affermare (first-person singular present afférmo, first-person singular past historic affermài, past participle affermàto, auxiliary avére)[1]

Etymology

It is borrowed from Latin affirmō (“to strengthen; to assert”), made of ad- and firmō (“to make firm”), from firmus (“firm”).[2][3][4][5] DELI calls it learned and Nocentini a borrowing from Latin.[2][3] The GDLI adds that it spread with the language of scholastic logic and philosophy.[6]

The LEI instead counts it among the words that continue the Latin verb, beside Old French afermer (1119), Old Occitan afermar and Catalan afermar.[7] For the LEI only the form Old Italian affirmare is a Latinism, like French affirmer and Spanish afirmar.[7]

The adjective goes back to Proto-Italic *fermo- and Proto-Indo-European *dʰer-mo- (“holding”).[8]

Earliest recorded meaning

The TLIO's first record is in Patecchio's Splanamento, from Cremona, early in the 13th century, where it means to assert something as true.[9][7] DELI's first dates are in Guittone d'Arezzo, before 1294, for “to declare as certain” and “to say yes”.[2]

Semantic evolution

Guittone writes a postutto t'afermo, “I tell you for certain”.[6] In Old Italian the verb also meant to swear to something, to approve, to prove by argument, to guarantee and to make stronger.[9] The sense “to strengthen” grew rare after the 14th century.[7] Dante condemns the fool who senza distinzione afferma o niega, who affirms or denies without distinguishing.[10]

The reflexive affermarsi “to grow stronger” is in the Palladio translation of 1340.[2] Its modern sense, “to make one's name, to succeed”, is recorded in 1884, and the LEI suggests a semantic loan from French s'affirmer.[2][7] The noun affermazione followed with the sense “success, victory” in 1923, and affermato “well known, established” in 1955.[2]
