Pronunciation

  • Ecclesiastical: [a.ri.us][1]

Forms

-ārius (feminine -āria, neuter -ārium); first/second-declension suffix[1]

Etymology

The suffix is inherited from Proto-Italic *-āzios,[1] which the OLD writes *-āsios,[2] also seen in Oscan sakrasias and Umbrian plenasier, a locative plural meaning “Ides”.[2][1][3] Wiktionary analyses it as *-āso-, from Proto-Indo-European *-eh₂so-, compare the Hittite suffix -ašša-, extended with *-yós (“belonging to”).[1] Weiss holds that there is no certain analysis of the Italic form; one suggestion builds it on a genitive singular in ⟨-ās⟩, and he finds the same formation in cognomina of non-Roman origin such as Vespāsius.[3] The noun in -ārius is this adjective used substantively.[1][3]

Earliest recorded meaning

Plautus already has the adjectives onerārius “for carrying loads” and vīnārius “pertaining to wine” and the noun argentārius “banker”, from argentum.[3]

Semantic evolution

The adjectives were often turned into names of trades,[3] so that the masculine noun commonly means a dealer or worker in something.[2][1] This agent use is the main one to survive in Romance: French -ier, Spanish -ero and Italian -aio.[3] The neuter and feminine also became suffixes of their own, -ārium and -āria.[2]
