• Grex (horticulture) on Wikipedia.Wikipedia

From Proto-Italic *greks, from Proto-Indo-European *h₂ger- (“to assemble, gather together”) (though de Vaan prefers to reconstruct the Proto-Italic as *gʷreg-, and the Proto-Indo-European as *gʷreg- (“group, herd”)). Cognates include Lithuanian gurguole (“mass, crowd”) and gurgulys (“chaos, confusion”), Old Church Slavonic гръсть (grŭstĭ, “handful”), Welsh gre (“herd”), Ancient Greek γάργαρα (gárgara, “heaps, lots (of people, etc.)”), Khotanese (haṃ-grīs, “to gather, assemble”).

Properly, a herd or drove of larger animals form a pecus n, a iūmentum (when pulling carts), or an 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.
