-atus

See also: atus and -átus

Latin

Etymology 1

From Proto-Italic *-ātos, from Proto-Indo-European *-eh₂tos. A "pseudo-participle" possibly related to -tus, though similar formations in other Indo-European languages show that it was distinct from it already in Indo-European times.

Cognate to Proto-Slavic *-atъ, Proto-Germanic *-ōdaz (English -ed (“having”)).

Suffix

-ātus m (feminine -āta, neuter -ātum); first/second declension

    barba (“beard”) → barbātus (“bearded, having a beard”)
    rēticulum (“small net”) → rēticulātus (“reticulated, net-like”)

By rebracketing of action nouns in -tus, -tūs formed from first conjugation verbs, such as mercātus (mercor + -tus) or pecūlātus (peculor + -tus), where -ā- is actually part of the stem.
