Etymology and origin of the Italian word fatto
Pronunciation
- /ˈfat.to/[1]
Forms
fatto m (plural fatti)[1] As an adjective, the past participle of fare, it is fatto, feminine fatta, plural fatti, fatte.[1][2]
Etymology
It is inherited from Latin factum (“deed, act”), the noun use of factus (“made, done”), the past participle of faciō (“to make, do”), which gave fare.[3][4][5][1] Nocentini notes that the participle took both the noun sense “something done” and the adjective sense “developed, ripe”.[4] The word is panromance: French fait, Occitan fach, Catalan fet, Spanish hecho, Portuguese feito, Sardinian fattu and Romanian fapt.[4][6][7]
The Latin verb goes back to Proto-Indo-European *dʰeh₁- (“to put, place”), through Proto-Italic.[1] Devoto observes that the participle was built on the present stem with its ⟨-c-⟩, not on the bare root, which would have given a form like Ancient Greek θετός (thetós).[8]
Earliest recorded meaning
Nocentini dates the word to 1219, and GRADIT gives “before 1219” for the sense of a story or plot.[4][5] In DELI the first records are in Bono Giamboni, before 1292, for “accomplished” and, as a noun, “an action done” and “the content of a literary work”.[3]
Semantic evolution
In Old Italian the noun meant above all a deed or exploit, the plural fatti a person's actions, as in Dante's gran fatti of the families of Florence (Paradiso 16).[9] Boccaccio has venire al fatto “to come to the point”, and fatto d'arme, a battle or armed clash.[10][11] From these grew the modern senses: an event that really happened, as opposed to words or ideas (fatti, non parole), and, in the plural, one's own business (farsi i fatti propri).[5][12]
The adjective developed senses of its own: “ripe” (before 1348, Giovanni Villani), “adult” (Francesco da Barberino), “cooked” (Mattioli, before 1563), and in recent slang “high on drugs” or “exhausted”.[3][5][9] Words built on the plural include the conjunctions infatti (1566) and difatti, and the adverb affatto (1274), which now often means “not at all”.[4] The pejorative fattaccio, a shocking deed or a crime of blood, is a Roman word.[3]
