Pronunciation

  • IPA (Louisiana): /fɾæ(ɾ)/[1]

Forms

frère m (plural frères)[1] Early Old French fradre (842), then fredre and frere (1080).[2][3][1]

Etymology

It is inherited from Old French frere, inherited from Latin frāter (“brother”), accusative “frātrem”.[2][3][4][5][1] The Latin word continues Proto-Indo-European *bʰréh₂tēr (“brother”), as do Ancient Greek φράτηρ (phrátēr, “member of a brotherhood”), German Bruder and English brother.[3][6][1] In the old patriarchal system the word probably named men of the same generation, not necessarily born of the same parents; for the narrower bond, Greek used ἀδελφός (adelphós), and Latin “frāter germānus” “brother of the same blood”, whence Spanish hermano and Portuguese irmão.[3][6]

Latin “frāter” also meant an ally, a friend and a member of a brotherhood, and Christians called one another so; hence it came to mean “monk”, the sense of Italian frate and Portuguese frade, while Italian “fratello” is a diminutive.[3][6][4]

Cognate with Occitan fraire and Romanian frate.[6][4]

Earliest recorded meaning

It is first found as fradre in the Strasbourg Oaths (842), meaning a brother born of the same parents; the Chanson de Roland (about 1100) has frere.[2][3]

Semantic evolution

About 1050 the Vie de saint Alexis already uses it for a fellow human being, and, from 1174–1176 it named a member of a religious community, as in frères mineurs (about 1360) and frères prêcheurs.[2][7] Legal French distinguishes the frère germain (13th century), consanguin (14th century) and utérin (mid-15th century); frères de lait dates from 1538, frères ennemis from 1487 and faux frère from 1675.[7] In familiar use it is a friend or comrade, vieux frère (early 20th century).[7][1]
