operārius (feminine operāria, neuter operārium); first/second-declension adjective[1]
Etymology
It is from Latin opera (“work, effort”) + -ārius, from opus.[2][1] De Vaan reconstructs ⟨opus⟩ as Proto-Italic *opes- (“work”), Proto-Indo-European *h₃ep-os (“work”), cognate with Oscan ⟨úpsannúm⟩ “to be made”.[3]
Earliest recorded meaning
Köbler's earliest source is Plautus.[4] Köbler dates Plautus c. 250–184 BC.[4]
Semantic evolution
As an adjective it meant working for hire, labouring, as in Cicero's homō operārius; of animals and tools used in farm or other work, as of operārium pecus “working cattle” in Columella; and in Pliny used by labourers.[2] As a noun it meant a hired worker, labourer, mechanic.[2][5]
In Ecclesiastical Latin it means working, and as a noun labourer, worker.[6] Medieval Latin used the noun for a building worker, a tiller, and the warden of a church's fabric fund.[7]
