Katsetav

Katsetav is an Estonian linguistic term that functions as the present participle of the verb katsetama, meaning "to test." As an adjective, katsetav roughly translates to "testing," "experiential," or "experimental" and is used to describe actions, processes, or objects characterized by testing or experimentation. The form is built from the noun katse ("test") plus the participial suffix -tav, which signals ongoing action or a characteristic.

In technical and academic language, katsetav is commonly used to label environments, methods, or artefacts that are intended for testing, for example katsetav keskkond (testing environment), katsetav prototüüp (experimental prototype), or katsetav meetod (testing method). It can describe projects or study phases that are exploratory rather than final.

Usage notes: As with other Estonian adjectives, katsetav agrees with the noun in number and case. It is not typically used as a proper noun or organization name.
