From Old Latin -ios, from Proto-Italic *-i(j)os, from Proto-Indo-European *-yós. Cognate with Ancient Greek -ῐος (-ĭos).
The suffix -ius is added to a noun to form an adjective indicating "made of" or "belonging to" that noun.
In taxonomics, out of analogy with ancient Roman nomina gentilicia, this suffix is added to surnames ending in a consonant other than the ending -er and, sometimes, replacing a mute final -e.
First/second-declension adjective.
From Proto-Italic *-osjos, itself from Proto-Indo-European *-ósyo (genitive case suffix) secondarily marked with the genitive *-s.
