tyhjentyessään

tyhjentyessään is a Finnish word that functions as an adverbial participle. It is the translative case of the third infinitive of the verb tyhjentyä. The verb tyhjentyä means to become empty or to be emptied. Therefore, tyhjentyessään literally translates to "while becoming empty" or "in the process of becoming empty."

This grammatical form is used to describe an action or state that occurs concurrently with the process of something emptying. It implies a temporal relationship, indicating that another event or situation is happening at the same time as the emptying. For example, one might say "Säiliö suli tyhjentyessään" which translates to "The tank melted while emptying." Here, the melting is happening during the process of the tank becoming empty.

The usage of tyhjentyessään is relatively specific and is often found in descriptive contexts where the simultaneous occurrence of two events is important to convey. It adds a nuanced temporal dimension to the sentence, highlighting the dynamic nature of the situation. It is not a commonly used word in everyday casual conversation but appears more frequently in written or formal Finnish. The structure of the word itself, with its "-essään" ending, is characteristic of Finnish adverbial participles indicating simultaneity.
