Forms

fratello m (plural fratelli or (obsolete) frategli, diminutive fratellìno, augmentative fratellóne (often, “member of a brotherhood”), pejorative fratellàccio, endearing fratellùccio)[1] Old Italian had many forms, among them northern fradello and fraello.[2] The old plural frategli is now obsolete.[1][3]

Etymology

It is inherited from Latin frātellus (“little brother”), a diminutive of frāter (“brother”).[1][4][5] DELI and Nocentini give it as a word of spoken Latin, DEI as a Late Latin word recorded by the grammarians.[6][7][8] In Tuscany and most of northern Italy the diminutive took the place of frate, which was left with the sense “friar”; in southern Italy and Sicily, by contrast, it is the diminutive that came to mean a monk.[8][9]

Paul Aebischer (1937), followed by Giuliano Bonfante (1973), argued that the word is not a direct continuation of the Latin one but a late learned revival, since until about 1130 a brother was still called by the descendant of germānus (“of the same parents”).[6]

The plain Latin noun survives as Romanian frate, French frère and Old Occitan fraire, and in the sense “friar” as Spanish fraile and Portuguese frade.[9] It goes back to Proto-Italic *frātēr, Proto-Indo-European *bʰréh₂tēr (“brother”), and is cognate with Ancient Greek φράτηρ (phrátēr, “member of a brotherhood”), Old Irish bráthair and brother.[10][1][4]

Earliest recorded meaning

The TLIO's first record is in the Genoese Contrasto of the troubadour Raimbaut de Vaqueiras, about 1190.[2] DELI's first Tuscan record is a Florentine account book of 1211, with the sense “a man born of the same parents as another”.[6][5]

Semantic evolution

In Old Italian the word took several qualified forms: fratello carnale and fratello germano for a full brother, and fratello cugino for a cousin.[2] It was also used for any man as a fellow human being, and as an affectionate form of address.[2] Dino Compagni (1310–1312) uses it for one bound to others by a religious, political or social tie, and the statutes of the Disciplinati of Siena (13th–15th century) for a member of a lay confraternity.[6][2]

The noun fratellanza “brotherhood, fellowship” is in Dante (1304–1308), and in 1602 it named a mutual-aid society.[6] Fratellastro “half-brother” comes from northern Italy (Venetian fradelastro 1829, Milanese fradellaster 1840) and entered common Italian only in the second half of the 19th century.[6] Zingarelli records the use after a noun, partiti fratelli “sister parties”, in 1970.[6]

Recent uses are calques of English: young people's fratello for a friend follows American brother, and Grande Fratello, the all-seeing totalitarian state, follows Orwell's Big Brother.[11]

Usage notes

Like other names of relatives, fratello takes no article after a possessive (mio fratello).[12][13] In the old dialects of Pavia and Treviso the word for “sister” was remade on the masculine, as frela and fradella.[8] The set phrase fratello di latte means a foster brother, one nursed by the same woman.[5][14]
