Further reading[edit]



From Proto-Indo-European *h₂ger- (to assemble, gather together). See also Lithuanian gurguole (mass, crowd) and gurgulys (chaos, confusion), Old Church Slavonic гроусти (grusti, handful), and Ancient Greek ἀγείρω (ageírō, I gather, collect), whence ἀγορά (agorá). See Proto-Germanic *kruppaz (lump, round mass, body, crop).



grex m (genitive gregis); third declension

  1. (zoology) A group of smaller animals: a flock (of birds, sheep, etc.), a pack (of dogs, wolves, etc.), a swarm (of insects), etc.
  2. (figuratively) A similar group of other things, particularly:
    1. A group of people: a crowd, a clique, a company, a band, a troop, etc.
    2. (sports) A team of charioteers.

Usage note[edit]

Properly, a herd or drove of larger animals form a pecus n, a iumentum (when pulling carts), or a armenta (when pulling a plow), while smaller animals—especially domesticated pecudēs—form a grex. Its use for people is not necessarily pejorative in the way pecus is.


Third declension.
