Wechselpräpositionen
This is the trickiest single point in the whole course so far - genuinely worth taking slowly. A handful of common place prepositions can trigger either accusative (Lesson 7) or dative (Lesson 18), and the choice depends on one simple question you ask yourself before speaking.
| Wohin? (movement toward a destination) | → accusative |
| Wo? (fixed location, no movement) | → dative |
Ich gehe in die Küche. (Wohin? Into the kitchen - accusative)
Ich bin in der Küche. (Wo? In the kitchen - dative)
Nothing else in the sentence changes - only the article, and only because one describes arriving and the other describes already being there. Full table with more prepositions: Reference - Two-Way Prepositions.
Motion verbs (gehen, fahren) usually mean accusative is coming. State verbs (sein, liegen - "to be lying") usually mean dative. This isn't a hard rule, but it's a fast first guess while you're still building the "wohin/wo" reflex.
1. "I'm going into the kitchen." (die Küche) - Ich gehe in ______ Küche.
2. "I'm in the kitchen." (die Küche) - Ich bin in ______ Küche.
3. Which question signals accusative?
4. Which question signals dative?
5. Name two of the nine two-way prepositions besides "in."

This point takes real repetition to feel natural - ask your teaching agent for more wohin/wo practice sentences whenever you want.
