Questions & Answers about Am Zoll öffne ich meinen Koffer.

Why does the sentence start with Am Zoll instead of ich?

German often puts the time, place, or other important context first. Here, Am Zoll is placed in the first position to emphasize where the action happens.

But in a normal main clause, the conjugated verb must still be in the second position, so you get:

Am Zoll | öffne | ich | meinen Koffer

This is why ich comes after the verb here. If you started with ich, the sentence would also be correct:

Ich öffne am Zoll meinen Koffer.

Both are grammatical, but the original version gives more focus to the location.

What does am mean here?

Am is a contraction of an dem.

So:

• an dem Zoll → am Zoll

In this sentence, am Zoll means something like at customs or at the customs checkpoint/desk.

This kind of contraction is very common in German, just like:

• im = in dem
• vom = von dem
• zum = zu dem

Why is it am Zoll and not im Zoll?
