käynnistäessään

käynnistäessään is a Finnish word that functions as a present active participle in the genitive case. It is derived from the verb "käynnistää," which means "to start," "to launch," or "to initiate." The "-essään" ending signifies "while doing" or "upon doing" something, and the genitive case here indicates possession or a specific point in time related to the action.

Therefore, "käynnistäessään" translates to "upon starting," "when starting," or "while initiating" something. It is used to describe an action that occurs at the moment another action begins. For instance, one might say "Hän oli väsynyt käynnistäessään autoa," which translates to "He was tired when starting the car." In this context, "käynnistäessään" specifies the exact time of his tiredness – the moment he began the act of starting the car.

The word is employed in various contexts, from mechanical operations like starting an engine to more abstract concepts like starting a project or a new phase of life. It conveys a sense of immediate consequence or simultaneous occurrence with the act of starting. The grammatical structure allows for a concise way to link two events, where one directly follows or happens at the same time as the initiation of another.
