Forms

officiārius m (genitive officiāriī or officiārī); second declension[1]

Etymology

It is from Latin officium (“service, duty, office”) + -ārius.[1][2][3]

Earliest recorded meaning

The TLL's only Late Latin example is in a letter ascribed to Ambrose, on the passion of Gervasius and Protasius, where the consular Paulinus speaks to an officiarius.[2]

Semantic evolution

In Late Latin it meant the same as officiālis, an official.[2] Medieval sources use it of a household servant, a manorial agent and a court bailiff;[4] in Britain of royal and church officers and of a monk who officiates at the liturgy.[5] As an adjective it described people or rooms busy with some task, and late British records also have a neuter plural for business and a feminine for a body of officials.[5]

English officer came from it through Old French.[6]
