tegutsemisega

Tegutsemisega is the Estonian comitative/instrumental form of the noun tegutsemine, meaning "action," "activity," or "acting." Morphologically it combines the verb stem tegutse- (from tegutsema, "to act") with the nominalizer -mine to form tegutsemine, and the case ending -ga to indicate accompaniment or means. The word therefore conveys "with the action," "by acting," or "through activity."

In use, tegutsemisega appears in contexts that describe how something is achieved or accompanied. For example: "Tema edu tuli sihikindla tegutsemisega" (His success came through determined action). It can express instrumentality ("with the action of…"), manner ("by acting in a certain way"), or association ("together with activity").

Tegutsemisega is common in both formal and informal Estonian, especially in discussions of work, policy, management, and social action, where emphasis is placed on the means or manner of intervention. Related forms include tegutsema (verb), tegutsemine (basic noun), and tegutsemiseks (illative/for the purpose of acting). English equivalents depend on context and include "by acting," "through action," and "with the activity of." The word follows regular Estonian noun inflection patterns and is readily analyzable by its stem, nominalizer, and case ending.
