Pronunciation

  • Classical: [ɔ.nɛˈraː.ri.ʊs][1]
  • Ecclesiastical: [o.neˈraː.ri.us][1]

Forms

onerārius (feminine onerāria, neuter onerārium); first/second-declension adjective[1]

Etymology

It is from Latin onus (“load”) + -ārius.[2][1][3] The noun onus goes back to Proto-Italic *onos and Proto-Indo-European *h₃en-os (“load”).[4] Cognate with Sanskrit अनस् (ánas-, “heavy cart”).[4]

Earliest recorded meaning

The Thesaurus finds it in a few passages each from Naevius, Plautus, Sisenna and Cicero on.[3]

Semantic evolution

It means used for carrying loads, especially of ships: navis oneraria is a cargo ship or transport, opposed to the light actuaria in Sisenna and frequent in Caesar.[2][5] Livy has iumenta oneraria, beasts of burden.[5] As a feminine noun, with navis understood, oneraria is a merchant ship or transport, as in Cicero.[2][5]

  • c. 250–184 BC – Plautus.[3][6]
