German prepositions are small words with big influence. In German, a preposition usually controls the grammar shape of the noun phrase that follows it, a rule often called case governance. If the case is wrong, even a perfect sentence can feel “off” to native readers, like a key that almost fits the lock.
Core idea: preposition → case → the article/pronoun ending changes. Learn pairs like mit + dative or für + accusative, and your accuracy rises fast.
What Case Governance Means
- Case governance (German term: Rektion) means a word requires a specific case in its complement.
- With prepositions, this is extremely visible because the next word often changes form: der → dem, das → das, die → der.
- Most German prepositions are one-case (always accusative, always dative, or mostly genitive). A special set is two-way: the case depends on meaning, not on “style.”
Think of a preposition as a socket: it accepts only one “plug” shape (a case), and the article ending is the plug you can see.
Case Endings You See Most After Prepositions
Many learners know the rule but miss the visible signal: the article ending. This compact map focuses on what matters most for German prepositions and case governance.
| Case After The Preposition | Masculine | Feminine | Neuter | Plural |
|---|---|---|---|---|
| Accusative | den | die | das | die |
| Dative | dem | der | dem | den (+ -n often on the noun) |
| Genitive | des (+ -s/-es often on the noun) | der | des (+ -s/-es often on the noun) | der |
Useful contractions show up constantly in real German: im (in dem), am (an dem), zum (zu dem), zur (zu der). They do not change the rule; they just hide the ending in a neat package.
Accusative Prepositions
Always accusative is a clean category: once learned, it stays stable in almost every normal sentence.
- durch (through)
- für (for)
- gegen (against)
- ohne (without)
- um (around / at)
- bis (until; often used with no article)
- entlang (along; commonly placed after the noun)
Fast examples make the rule feel real. Watch the accusative article in each line.
- Ich gehe durch den Park.
- Das Geschenk ist für die Lehrerin.
- Wir spielen ohne das Handy.
- Er läuft entlang den Fluss.
Notes That Prevent Common Mistakes
- bis often pairs with place names or adverbs: bis morgen, bis Berlin. With an article, learners frequently add another preposition: bis zum Bahnhof.
- entlang can appear after the noun phrase: den Fluss entlang. The case stays accusative.
Dative Prepositions
Always dative prepositions are among the most frequent in everyday German, so they repay practice quickly.
- aus (out of, from)
- außer (except for)
- bei (at, near, with a person)
- mit (with)
- nach (after; to)
- seit (since, for)
- von (from, of)
- zu (to, at)
- gegenüber (opposite; can follow the noun)
Spot the dative forms dem/der/den. This is the heart of case governance in action.
- Ich komme aus dem Büro.
- Wir reden mit der Nachbarin.
- Er fährt zu dem Arzt. (zum)
- Das Café ist gegenüber der Bank.
A Simple Dative Reality Check
- If you see mit or von, expect dem/der/den.
- If you see zu, listen for contractions: zum, zur.
Genitive Prepositions
Genitive governance shows up often in writing and careful speech. Many of these prepositions feel a bit “official,” which can be helpful: when you see them, the genitive signal is a strong clue.
- wegen (because of)
- trotz (despite)
- während (during)
- statt / anstatt (instead of)
- innerhalb / außerhalb (within / outside of)
- oberhalb / unterhalb (above / below)
- aufgrund (due to)
In real usage, a few of these prepositions also appear with dative in informal contexts. If the goal is a neutral, widely accepted standard, the genitive is the safer default for wegen, trotz, and während.
- wegen des Wetters bleiben wir zu Hause.
- trotz der Verspätung kommt er pünktlich an.
- während des Meetings bitte leise sein.
Two-Way Prepositions
Two-way prepositions (German: Wechselpräpositionen) are the famous exception that is not really an exception. The preposition stays the same; the meaning decides the case: direction usually triggers accusative, and location usually triggers dative.
The two-way set (memorize as one chunk):
- an
- auf
- hinter
- in
- neben
- über
- unter
- vor
- zwischen
Fast decision test with two questions:
- Wohin? (Where to?) → typically accusative
- Wo? (Where?) → typically dative
Motion vs. position is the backbone of case governance here.
| Meaning | Typical Question | Case | Example |
|---|---|---|---|
| Goal / direction | Wohin? | Accusative | Ich lege das Buch auf den Tisch. |
| Location / position | Wo? | Dative | Das Buch liegt auf dem Tisch. |
Mini Pairs You Can Reuse
- in: Ich gehe in die Stadt. / Ich bin in der Stadt.
- an: Ich stelle die Flasche an den Rand. / Die Flasche steht am Rand.
- zwischen: Ich setze mich zwischen die Stühle. / Ich sitze zwischen den Stühlen.
- unter: Ich hänge das Bild unter das Regal. / Das Bild hängt unter dem Regal.
High-Value Chunks
Fluency grows when prepositions are learned as ready-made chunks, not as lonely words. Each chunk carries its case governance like a label on a folder.
- zu Hause (fixed phrase; no article)
- im Laufe des Tages (genitive)
- in der Nähe (dative)
- am Ende des Monats (genitive)
- auf jeden Fall (accusative)
Common Trouble Spots And Clean Fixes
- Mixing up nach and zu: use nach mainly with cities/countries and “after,” and zu with people, places, and destinations that feel like a point (doctor, office, station).
- Forgetting the plural -n in dative: mit den Kindern is a classic pattern worth memorizing.
- Overthinking two-way prepositions: ask Wohin? vs Wo?, then move on. Speed matters.
- Learning preposition + article pairs helps you write and speak more smoothly, because the ending comes out as one unit, not two words you assemble seperately.

FAQ
What does “case governance” mean in German prepositions?
Case governance means the preposition chooses the case of the next noun phrase. That choice changes endings you can see, like dem vs den.
Which German prepositions always take the accusative?
High-frequency accusative prepositions include durch, für, gegen, ohne, um, plus bis in many everyday patterns.
Which German prepositions always take the dative?
High-frequency dative prepositions include aus, bei, mit, nach, von, and zu (often heard as zum/zur).
How do two-way prepositions decide between accusative and dative?
For two-way prepositions, meaning leads: direction (Wohin?) tends to accusative, and location (Wo?) tends to dative.
Is genitive after prepositions still important?
Yes. Many writers prefer genitive after prepositions like wegen, trotz, and während, especially in formal or edited text.
