What are Two-Way Prepositions?
Two-way prepositions (Wechselpräpositionen) are German prepositions that take either the dative or accusative case depending on whether they describe location or movement. These nine prepositions are the most confusing in German because their case changes the meaning. Learning when to use each case is essential for accurate German.
Two-way prepositions are in, on, under, above, next to, between, in front of, behind, and over in German. They take the dative case for location (where?) and the accusative case for movement (where to?).
