tyhjennettyinä

The Finnish word "tyhjennettyinä" is the plural partitive case of the past passive participle of the verb "tyhjentää". "Tyhjentää" means to empty, to clear out, or to drain. Therefore, "tyhjennettyinä" translates to "as having been emptied" or "when emptied".

This grammatical form is used to describe a state of being or an action that has been completed and applies to multiple entities. For example, one might say "Laatikot olivat tyhjennettyinä" which translates to "The boxes were emptied" or "The boxes had been emptied." In this context, "tyhjennettyinä" describes the state of the boxes.

The partitive case is often used to indicate a part of something, or an incomplete action, but in the context of a past passive participle, it can also denote a state or condition resulting from the completed action, especially when referring to multiple items. The plural form indicates that the action of emptying applies to more than one object or entity. It is a descriptive term indicating the condition of multiple things after being emptied.
