wo? · wohin? · woher?

You already do half of this in English

Shortcutwo? → Dativ (it stays) · wohin? → Akkusativ (it goes). Same preposition, two faces.

You never stop to think about the difference between into the kitchen and in the kitchen. One is arrival, the other is being there. Jump onto the table · sit on the table. Nobody taught you this as a table; the little word told you.

German asks for exactly the same reflex. There is one difference: the signal is not a separate word, it sits on the article. The preposition itself never changes — the only thing that changes is the article that follows it.

English only does this for a couple of words (in/into, on/onto) and shrugs at the rest: behind the house means both. German has nine prepositions that split, and every one of them behaves the same way — the pairs below show it.

These nine prepositions are called Wechselpräpositionen in German — “switching prepositions”. Every other preposition has a fixed case; there you have no choice, and nothing to think about.

The one question that decides it

You ask the sentence a single question: “wohin?” or “wo?” Is something going somewhere, or is it just sitting somewhere? Once you have the answer, you have the case.

• wohin? · where to? → something arrives somewhere new, a boundary is crossed → Akkusativ
• wo? · where? → the place where it already is is described, no boundary → Dativ

Now the real work: you have answered the question, so what does the article become? The four rows below are the engine of this page. der is masculine, die feminine, das neuter — and in the plural it is die again.

It is the target, not the verb, that decides. “If the verb shows movement, use the Akkusativ” works in week one and misleads you in week two — you will see why in section 5.

The nine prepositions — the table to save

The list is closed and short: nine. No other preposition offers this choice. What you need to memorise is not “which preposition takes which case” — it is which prepositions are on this list of nine.

One row in the table looks odd: next to in den Park it says im Park. That is because some preposition + article pairs fuse in German, and writing them apart sounds wrong.

The verb changes too: put ≠ be

English uses two different verbs as well: I put the book on the table and the book is on the table — and the famous pairs lay/lie and set/sit, which even native speakers mix up. German does the same thing in pairs, and the case of each pair is fixed: the left side is always Akkusativ, the right side always Dativ.

If you get stuck between legen and stellen, look at how the object sits: lying down means legen/liegen, upright means stellen/stehen. A plate lies on the table (liegt), a glass stands on it (steht). Germans really do make this distinction.

The part nobody teaches: movement ≠ boundary

The “movement means Akkusativ” rule falls apart right here. In both sentences below you are running — so there is movement all the way — but the cases differ.

The real name of the rule is not movement, it is boundary. The right question is: are you entering the area the preposition draws? If not, it is Dativ, however fast you move; if you are, it is Akkusativ, even when you cannot see any movement at all.

There is a flip side too: sentences that look as if nothing moves can take the Akkusativ. Because something reaches a target there.

Bonus: with über, the difference between the two cases changes the meaning completely. Wir fahren über die Brücke. = we cross the bridge (Akkusativ, we get to the other side). Die Wolken sind über der Brücke. = the clouds are above the bridge (Dativ, they just hang there).

Three places where the rule does not work at all

Everything so far is logic for sentences that describe a place. In three spots that logic never even comes into play — go in knowing that, or the rule you know will mislead you.

Each of the nine has its own page

Everything so far covers the rule: Dativ for the wo? question, Akkusativ for wohin?. But every preposition also has its own story — an points to days too (am Montag), über meaning “about” breaks the pattern and always takes the Akkusativ, vor means “ago/before” in time and the case never changes there. Each of the pages below opens up one single preposition all the way.

Prepositions with a fixed case (für · mit · aus · bei…) are not part of this group; their list and their individual pages are on the prepositions page.

Change how you keep your notebook

This topic is not solved by “studying”, it is solved by changing how you write things down. As long as you write the verb on its own, you will guess the case again in every sentence.

• Instead of: legen = to put
• Write: legen (+ Akk) ↔ liegen (+ Dat) = to put ↔ to be lying

Write the verb as a pair and put its case next to it. German has no single box called “put”: the verb that puts and the verb that stays are two different words with two different cases.

• Step 1 — In the sentence, look at the target first, not the verb. Is something arriving at a new place?
• Step 2 — Ask the sentence wohin? If you get an answer, it is Akkusativ; if the question sounds silly, ask wo? and the answer is Dativ.
• Step 3 — Find the article: masculine den / dem, feminine die / der, neuter das / dem, plural die / den + –n.
• Step 4 — Once a day, build a pair of sentences for five objects in your room: Ich stelle die Tasse auf den Tisch. — Die Tasse steht auf dem Tisch. After two weeks you make the call without thinking.

The check nobody tells you: every article ending in –m is Dativ. dem · einem · meinem · ihrem — no exceptions. The reverse is not true (the feminine Dativ is der), but the moment you see an -m while reading your sentence, you can confirm “this one gives a location”.

One last door: in everyday speech Germans split wohin and woher in two. You will not see it in the textbook, but you will hear it on the street on day one.

The same particle hin sticks to verbs too and gives you a free signal: if hin is inside hinlegen · hinstellen · hinsetzen, the sentence is going to a target — so Akkusativ. Setz dich hin! · Leg dich hin!
