keskittyessään

The Finnish word "keskittyessään" is a temporal adverbial participle form of the verb "keskittyä." "Keskittyä" translates to "to concentrate," "to focus," or "to center." Therefore, "keskittyessään" essentially means "while concentrating," "when focusing," or "in the process of concentrating."

This grammatical form is used to describe an action that happens concurrently with another action, where the subject of both actions is the same. For example, one might say "Hän oppi uusia asioita keskittyessään" which translates to "He learned new things while concentrating." The participle indicates that the learning occurred at the same time as the act of concentration. It implies a state of focused attention during a particular period or activity. The nuance of "keskittyessään" is its passive or involuntary implication, suggesting that the concentration is happening as a natural consequence of being engaged in an activity, rather than necessarily a deliberate effort to start concentrating. It's a way to describe a state of mind within a narrative.
