Concertovat

Concertovat is not a standard Czech infinitive with its own established meaning. The proper Czech verb for giving a musical performance is koncertovat, which means to perform a concert. The spelling concertovat is often considered a nonstandard form or a misspelling in Czech texts. When encountered, it is usually interpreted as a mistaken variation of koncertovat or, less commonly, as an anglicism.

If someone uses concertovat to mean “to act in concert with others” in a Czech context, it is generally better to use Czech equivalents that are standard and unambiguous. Common formulations include koordinovat kroky s ostatními (coordinate actions with others), jednat ve shodě s jinými (act in accord with others), or jednat v kooperaci. In legal or formal texts, precise terms such as koordinace, spolupráce, or jednání ve shodě are preferred, and the more colloquial or incorrect form concertovat is usually avoided.

In everyday usage, the verb koncertovat remains strictly about performing a concert. For example: Skupina A bude koncertovat v Praze příští měsíc. Here the meaning is clear and conventional.

Summary: concertovat is not recognized as a separate standard Czech verb with a distinct meaning. The correct term for performing is koncertovat. When the idea is to describe coordinated action with others, use standard Czech expressions such as koordinovat, jednat ve shodě, or jednat v kooperaci.
