-atus
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. Compare -ītus, -ūtus.
Cognate to Proto-Slavic *-atъ, Proto-Germanic *-ōdaz (English -ed (“having”)).
Suffix
-ātus (feminine -āta, neuter -ātum); first/second-declension suffix
- -ed. Used to form adjectives from nouns indicating the possession of a thing or feature.
- Used to form adjectives from other adjectives, especially color names, with the sense "wearing [adjective](-colored) clothes".
- -like, -ate. Used to form adjectives from nouns indicating a resemblance or likeness to the noun.
- rēticulum (“small net”) + -ātus → rēticulātus (“reticulated, net-like”)
