Etymology

It is from Latin oleum (“olive oil”) + -ārius, or from olea “olive tree”.[2][3][1] ⟨oleum⟩ is from Ancient Greek ἔλαιον (élaion, “olive oil”), and ⟨olea⟩ from Ancient Greek ἐλαία (elaía, “olive tree”).[1]

Earliest recorded meaning

Köbler's earliest sources are Plautus and Cato, who has cella oleāria “oil store”.[4][5] Köbler dates Plautus c. 250–184 BC and Cato 234–149 BC.[4]

Semantic evolution

As an adjective it meant of or connected with olive oil, as in Cato's cella oleāria and Cicero, and of olives; its neuter was an oil jar.[2][5] As a masculine noun it was a maker or seller of olive oil.[2]

In Ecclesiastical Latin it meant of olive oil.[6] In Medieval Latin it was an oil dealer.[7] British Medieval Latin used it for containing olive oil, and as a noun for an oil jar.[8] It survives as French oléaire and Italian and Spanish oleario.[1]
