Firstly, I would like to give some background info. My German teacher has explained to us (the class) when to use Dativ and Akkusativ with Wechselpräpositionen. The rule roughly goes like this: If an action is not yet finished then one must use Akkusativ, and Dativ otherwise.
However we encountered these two (unrelated) sentences while completing exercises:
- Kannst du die Hausschuhe unter das Bett stellen? (notice Akkusative in Bold)
- Ja, hier schon. Aber in unserer Wohnung können wir diese Kommode nicht zwischen die Fenster stellen. (first one Dativ, and then the next one is Akkusativ, I think?)
This does not seem to fit the rule that the teacher explained. Could you help me out to understand why in the second sentence is the first bold part in Dativ and not Akkusativ? Maybe there was a mistake?
Danke für Ihren Hilfe!
