grex

Etymology and origin of the Latin word grex

Pronunciation

  • IPA (Classical): [ˈɡrɛks][1]
  • IPA (Ecclesiastical): [ˈɡrɛks][1]

Forms

grex m (genitive gregis); third declension[1]

Etymology

It goes back to Proto-Italic *gʷreg-, inherited from Proto-Indo-European *gʷreg- (“group, herd”).[2][1] De Vaan connects Khotanese haṃ-grīs- (“to gather”) and, with a reduplicated variant, Ancient Greek γάργαρα (gárgara, “heaps, crowds”) and Lithuanian gurguolė (“heap”);[2] Beekes takes the Greek and Lithuanian words as independent imitative formations.[1] Others start from Proto-Indo-European *ger- (“to gather”), as Pokorny and Köbler do, and the OLD compares Ancient Greek ἀγείρω (ageírō, “to gather”).[3][4][5] Old Irish graig (“herd of horses”) and Welsh gre (“herd”) are probably borrowed from Latin, according to de Vaan.[2]

Earliest recorded meaning

It is attested from Plautus onwards.[2][4] In the Trinummus a wolf tries to drive off a whole flock.[5]

Semantic evolution

The word meant a flock or herd of animals, often sheep, and also a litter or brood, and poets used it for a cluster of stars.[5][6] Of people it meant a band or company, a crowd, and with contempt the common herd.[5] It also meant a circle of friends, a troupe of actors, a faction in the Circus, and a social class.[5]

Christian writers used it for the flock of the faithful, and medieval writers also for a religious community.[7][8] Its derivatives gregarius, egregius and congregare gave English gregarious, English egregious and English congregate.[2][9]
