  • IPA (Ecclesiastical): [ˈfraː.ter][1]

Forms

frāter m (genitive frātris); third declension[1]

Etymology

It is inherited from Proto-Italic *frāter, inherited from Proto-Indo-European *bʰréh₂tēr (“brother”).[2][1][3] Pinault analyses the Proto-Indo-European word as *bʰr-éh₂- “group of males borne by the same mother” with a contrastive suffix *-ter.[2] Cognate with Venetic vhraterei, Umbrian frater and Oscan fratrúm, with Old Irish bráthair and Welsh brawd, Sanskrit भ्रातृ (bhrā́tar-), Avestan brātar-, Ancient Greek φράτηρ (phrā́tēr, “member of a brotherhood”), Phrygian βρατερε (bratere), Armenian եղբայր (ełbayr), Old Prussian brāti, Lithuanian brólis, Old Church Slavonic братръ (bratrŭ), Gothic 𐌱𐍂𐍉𐌸𐌰𐍂 (brōþar), Old High German bruoder, Old Norse bróðir and Tocharian B procer, all “brother”.[2][4][5] Umbrian fratreks names an officer of a brotherhood.[2] Nigidius explained the word as “almost another self” (fere alter), Festus derived it from the Greek, and Isidore from frūctus.[6]

Earliest recorded meaning

It is found from Naevius onwards,[2] and Plautus calls Neptune the brother of Jupiter.[4][7]

Semantic evolution

It meant a brother, frater germanus a full brother, and in the plural brother and sister; a cousin on the father's side was frater patruelis or simply frater.[4][5] Caesar's Gauls called a kindred people their fratres, and the vocative mi frater was an affectionate address between friends; it also served as a euphemism for a lover.[4] The fratres arvales were members of a priestly college.[4]

Christian Latin used it for a fellow Christian and in the plural for the brethren, and medieval Latin for a monk or friar.[1][7][8] British texts distinguish the half brother and the uterine brother.[9] All Romance languages keep it, as Sardinian fratre, Romanian frate, Old French frere, Italian frate and Portuguese frade, the last two in the sense “friar”,[10][1] and English took fra and frate from Italian and frater as a learned word.[1]
