Questions & Answers about In der Stunde sprechen wir über den Film.
Because in is a two-way preposition (Wechselpräposition). It can take either:
- Accusative: when there is movement into something.
- Dative: when there is no movement, just location or time.
Here, In der Stunde refers to a time period (“during the lesson”), not movement into the lesson. So you use dative:
- in der Stunde = during the lesson / in class (dative)
- in die Stunde gehen = to go into the lesson (accusative)
Literally, in the hour, but in school context it usually means:
- in class / during the lesson / in this period
So In der Stunde sprechen wir über den Film naturally means:
- During the lesson we talk about the film.
