• -ōnsus (found in formōnsus, possibly the result of hypercorrection)

Etymology

Likely reflects a derivation *-h₃d-s-o- from Proto-Indo-European *h₃édos ~ *h₃édesos (“smell”), whence odor. Originally meaning “smelling like”, as evidenced possibly by hircōsus (“smelling like a goat”) and vinōsus (“fond of wine, *reeking of wine?”), it would have later generalised into “full of”. Compare related Ancient Greek -ώδης (-ṓdēs, “smelling like; full of”) and Old Armenian -ոտ (-ot) which underwent the same semantic change.

Alternatively, a derivation from Proto-Indo-European *-wénts has also been proposed, through a form such as *-wont-to- by suffixiation of *-tós.
