In, An, Vor: Is it Time or Place? How to Tell the Difference
Have you ever noticed that German prepositions like to lead a double life? You might see the word “in” in a sentence about a city, and then see it again in a sentence about a month.
Wait… is it a place or a time?
This is where many German learners get stuck. In German, we distinguish between Lokalpräpositionen (local) and Temporalpräpositionen (temporal). While the words often look the same, the way we use them—and the cases they trigger—can be very different.
Let’s break it down so you never get confused again!
What is the Main Difference?
At its simplest level:
- Local Prepositions: Answer the question “Wo?” (Where?) or “Wohin?” (Where to?). They describe a physical position or a direction.
- Temporal Prepositions: Answer the question “Wann?” (When?) or “Wie lange?” (For how long?). They describe a point in time or a duration.
The “Double Agents”: Prepositions that do both
There are a few prepositions that are very common in both categories. Let’s look at how they change meaning:
1. IN
- Local: Ich bin im (in dem) Büro. * (I am in the office — a physical place)
- Temporal: Ich komme im Sommer. * (I am coming in the summer — a point in time)
2. AN
- Local: Das Bild hängt an der Wand. * (The picture is on the wall — vertical surface)
- Temporal: Wir sehen uns am (an dem) Montag. * (We’ll see each other on Monday — a day of the week)
3. VOR
- Local: Das Auto steht vor dem Haus. * (The car is in front of the house — physical space)
- Temporal: Ich trinke einen Kaffee vor der Arbeit. * (I drink a coffee before work — time sequence)
The Case Rule: It’s Easier Than You Think!
One of the biggest struggles with local prepositions is deciding between Dative and Accusative (the “Wo vs. Wohin” rule). You can read more about that struggle in our guide on Dative vs. Accusative in German.
Pro Tip: While local prepositions change cases based on movement, temporal prepositions (like an, in, vor, nach) almost always take the Dative case! In German grammar, time is usually treated as a static “point,” so you can usually relax and stick with the Dative.
Summary Table: Time vs. Place
| Preposition | Meaning (Local/Place) | Meaning (Temporal/Time) |
| In | Inside a space | Months, seasons, future time |
| An | At / On a vertical surface | Days, parts of the day |
| Vor | In front of | Before |
| Nach | (Used for cities/countries) | After |
Final Thoughts
Mastering German prepositions is all about context. When you see a preposition, ask yourself: “Am I talking about a map or a calendar?” Once you identify if it’s a place or a time, the grammar becomes much easier to handle.
