lähteessään

LSOURCES lähteessään is a Finnish word that functions as an adverbial participle. It is derived from the verb "lähteä," which means "to leave" or "to depart." The suffix "-essään" indicates a possessive suffix, typically translating to "while leaving," "upon leaving," or "on his/her/its/their leaving."

The word describes an action or state that occurs concurrently with or immediately following the act of leaving. For example, one might say "Hän unohti lompakkonsa lähteessään," which translates to "He/She forgot his/her wallet while leaving." In this context, "lähteessään" specifies the time frame of forgetting the wallet.

The grammatical structure of "-essään" is a common way in Finnish to express simultaneous actions or temporal relationships. It attaches to the third-person singular or plural form of the verb stem. While the literal translation can be somewhat clunky in English, the meaning is generally clear from the context of the sentence. It conveys a sense of something happening as a consequence or during the act of departure. The usage is quite common in everyday Finnish speech and writing.
