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 noun.

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