Questions & Answers about Op het station koopt Sofie een broodje kaas.
This is because Dutch main clauses follow the V2 rule: the finite verb must be in the second position.
- If the sentence starts with the subject, you get: Sofie koopt een broodje kaas op het station.
- If the sentence starts with another element, like Op het station, the verb still stays second: Op het station koopt Sofie een broodje kaas.
So Op het station takes the first position, koopt must come second, and Sofie comes after the verb.
Usually op het station means at the station.
In Dutch, op is often used with places that English might express with at, especially for public places or locations in a general sense.
So:
- op het station = at the station
- not necessarily literally on top of the station
Dutch and English do not always use the same preposition for place expressions, so this is something you often just have to learn as a fixed phrase.
