Usage notesEdit

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.

Case Singular Plural
Nominative grex gregēs
Genitive gregis gregum
Dative gregī gregibus
Accusative gregem gregēs
Ablative grege gregibus
