See the coursesGerman two-way prepositions are one of those grammar topics that look complicated on paper but follow a surprisingly logical rule. Once you understand the core principle — movement vs. location — you will be able to use all nine of them with confidence.
These nine prepositions are called Wechselpräpositionen (literally "changing prepositions") because they switch between the accusative and the dative case depending on context. This guide walks you through each one with clear examples, the key rule you need to remember, common fixed expressions, and a mnemonic to make it all stick.
The nine Wechselpräpositionen are:
| Preposition | Core Meaning |
|---|---|
| an | at, on (vertical surface) |
| auf | on (horizontal surface), onto |
| hinter | behind |
| in | in, into |
| neben | next to, beside |
| über | over, above, across |
| unter | under, below, among |
| vor | in front of, before |
| zwischen | between |
These nine prepositions are the only ones in German that can take either the accusative or the dative. All other prepositions are locked to one case. For example, für is always accusative, and mit is always dative. But with the Wechselpräpositionen, you have to decide — and that decision follows one clear rule.
The rule is straightforward:
To figure out which case to use, ask yourself one of two questions:
Here is the same preposition used both ways:
Ich stelle die Vase auf den Tisch. (I place the vase onto the table.) — Wohin? → Accusative
Die Vase steht auf dem Tisch. (The vase is standing on the table.) — Wo? → Dative
In the first sentence, the vase is moving to the table. In the second, the vase is already there. Same preposition, different case, different meaning.
If you have already studied the German cases, you know that the accusative and dative change the article in front of the noun. Here is a quick refresher:
| Masculine | Feminine | Neuter | Plural | |
|---|---|---|---|---|
| Accusative | den | die | das | die |
| Dative | dem | der | dem | den (+n) |
The movement-vs.-location distinction is sometimes called the directional rule, and it is the single most important concept for mastering two-way prepositions.
Movement (Accusative) — The subject or object is changing position. Something is going from here to there. Typical verbs: gehen (go), legen (lay), stellen (place), setzen (sit down), hängen (hang up), fahren (drive to).
Location (Dative) — The subject or object is stationary. Something is already at rest. Typical verbs: sein (be), liegen (lie), stehen (stand), sitzen (sit), hängen (hang), bleiben (stay).
Notice the verb pairs: legen/liegen, stellen/stehen, setzen/sitzen. The first verb in each pair implies movement (accusative), and the second implies a resting state (dative). Learning these pairs is one of the fastest shortcuts to mastering Wechselpräpositionen.
Below is each preposition with an accusative (movement) and dative (location) example.
Some combinations of two-way prepositions have become fixed expressions where the case does not follow the movement/location rule. You simply need to memorize them. Many of these involve contractions (in + dem = im, an + dem = am, in + das = ins, an + das = ans).
These fixed expressions appear so frequently in everyday German that you will internalize them quickly through exposure. If you want to drill them actively, try our grammar quizzes which include preposition exercises.
Students have come up with many mnemonics over the years. Here is one of the most popular:
AN AUF HINTER IN NEBEN ÜBER UNTER VOR ZWISCHEN
Try this sentence to remember the first letters — A A H I N Ü U V Z:
An Allen Häusern In Nürnberg Üben Unzählige Vögel Zwitschern. (On all houses in Nuremberg, countless birds practice chirping.)
Or simply remember the rhythm: say the nine prepositions out loud as a list a few times, and the sequence will stick. Many learners find that singing them to a simple melody works even better.
Another approach: picture a box. The nine prepositions describe every spatial relationship to that box — on it, in it, behind it, in front of it, next to it, over it, under it, between it and something else, and at its surface. That mental image covers all nine.
As mentioned earlier, German has specific verb pairs that signal whether you need the accusative or dative:
| Accusative (movement) | Dative (location) | Meaning |
|---|---|---|
| legen (to lay) | liegen (to lie) | horizontal position |
| stellen (to place upright) | stehen (to stand) | vertical position |
| setzen (to set/sit down) | sitzen (to be sitting) | seated position |
| hängen (to hang up) | hängen (to be hanging) | hanging position |
When you see legen, stellen, or setzen, the preposition takes the accusative. When you see liegen, stehen, or sitzen, it takes the dative. This pattern is extremely reliable and works across all nine prepositions.

Two-way prepositions are one of those grammar points where understanding the rule is only half the battle. The other half is building enough muscle memory that you pick the right case without thinking.
