What Are German Two-Way Prepositions?
Two-way prepositions in German are prepositions that can govern either the accusative or dative case, depending on whether the context involves motion or location. The most common two-way prepositions are:
- an (at, on)
- auf (on, upon)
- hinter (behind)
- in (in, into)
- neben (next to, beside)
- über (over, above)
- unter (under, below)
- vor (in front of, before)
- zwischen (between)
The case you use with these prepositions depends on whether you’re talking about motion towards a place (accusative) or being at a place (dative).
Accusative for Motion: Expressing Direction
Use the accusative case when the preposition describes a change of position or movement towards a destination. In other words, if you can ask “Where to?” (Wohin?), the action involves motion, and the accusative case is required.
- Ich gehe in die Schule. (I am going into the school.)
- Er legt das Buch auf den Tisch. (He puts the book onto the table.)
- Wir stellen die Lampe neben das Sofa. (We place the lamp next to the sofa.)
Notice how the objects (Schule, Tisch, Sofa) follow the accusative case after the preposition, indicating motion.
Dative for Location: Expressing Position
When you want to describe where something or someone is located (no movement), use the dative case. Here, the question you can ask is “Where?” (Wo?).
- Das Buch liegt auf dem Tisch. (The book is lying on the table.)
- Wir sind in der Schule. (We are in the school.)
- Die Lampe steht neben dem Sofa. (The lamp is next to the sofa.)
In these examples, the nouns after the prepositions are in the dative case, showing position without movement.
Tips to Remember the Difference
1. Ask the Right Question
If you can ask Wohin? (Where to?), use the accusative. If you can ask Wo? (Where?), use the dative.
2. Remember the Case Endings
The articles for accusative and dative differ:
- Accusative: den (masc.), die (fem.), das (neut.), die (plural)
- Dative: dem (masc./neut.), der (fem.), den (plural)
3. Practice with Common Verbs
Some verbs naturally pair with motion (gehen, legen, stellen) and others with location (sein, liegen, stehen). Recognizing these patterns makes it easier to choose the correct case.
Examples for Everyday Situations
- Sie hängt das Bild an die Wand. (She is hanging the picture onto the wall.) – motion, accusative
- Das Bild hängt an der Wand. (The picture is hanging on the wall.) – location, dative
- Wir laufen über die Brücke. (We are walking over the bridge.) – motion, accusative
- Der Hund schläft unter dem Tisch. (The dog sleeps under the table.) – location, dative
Common Mistakes to Avoid
- Don’t confuse the cases: Always check if your sentence expresses motion or location.
- Watch out for false friends: In English, “in” can mean both “in” and “into,” but in German, the case changes the meaning.
- Be mindful of gender: The definite articles change with case and gender, so double-check your noun’s gender and case endings.
Practice Makes Perfect
The best way to internalize these rules is through regular practice. Try making your own sentences using each preposition with both cases.
