-ucus

See also: uçuş

Latin

Etymology

May be extended from Proto-Italic *-kos, from Proto-Indo-European *-kos, *-ḱos, thought to originally be a 'relational' suffix (compare -icus). In that case, most likely earlier *-oicos < *-oy-ḱo-s. This etymology is incomplete. You can help Wiktionary by elaborating on the origins of this term.
