opereer

Opereer is a term found in Dutch-language sources as an archaic or dialect variant of the verb opereren, meaning to operate, to function, or to perform a procedure. In standard contemporary Dutch, the preferred infinitive is opereren, and imperatives use forms tied to the present or imperative mood. The form opereer can appear in older texts as an imperative singular or as a historical/spelling variant, but it is not common in modern usage outside certain regional dialects or literary contexts.

Etymology and related forms: Opereer derives from the same root as opereren, itself from Latin operari (“to work”) and related to French opérer. The appearance of opereer reflects older Dutch spelling patterns and the broader historical influence of Romance languages on Dutch vocabulary and morphology. Over time, standardization favored opereren as the infinitive and opereer faded in everyday writing, surviving mainly in dialectal or quotation contexts.

Usage and examples: In contemporary Dutch, one would generally use opereren for the infinitive and the standard imperative forms of the verb. Opereer may be encountered in historical documents or regional speech as an imperative singular, for example, Opereer met zorg. When present in older prose, it can also appear as a less common or archaic present tense form. For learners of Dutch, opereer is best treated as an obsolete or dialectal variant rather than a living standard form.
