Etymology 1

From earlier Proto-Italic *-ās-(i)jo- (cf. Oscan sakrasias and Umbrian plenasier), formed from *-āso- (from PIE *-eh₂so-, cf. the Hittite appurtenance suffix -ašša-), extended with the relational adjectival suffix *-yós (“belonging to”).

Suffix

-ārius (feminine -āria, neuter -ārium); first/second-declension suffix

1. Used to form adjectives from nouns or numerals.

   ‎camera (“vault, arch”) + ‎-ārius → ‎camerārius (“climbing, creeping”)

   ‎ordō (“line, row”) + ‎-ārius → ‎ordinārius (“ordinary, of the rank and file”)

   ‎quaternī (“four at a time, by fours”) + ‎-ārius → ‎quaternārius (“quaternary”)

Usage notes

The nominative neuter form -arium, when appended to nouns, forms derivative nouns denoting a “place where things are kept”.
