Questions & Answers about Vid kassan frågar hon om vi behöver en påse.
Vid kassan means at the checkout, at the register, or at the till.
- vid = at, by, next to
- kassan = the checkout / the cash register
So this phrase places the action in the context of paying in a shop.
This is because Swedish follows the V2 rule in main clauses: the finite verb usually comes in the second position.
Here, the sentence starts with Vid kassan, so that takes the first position. The verb frågar must then come second:
- Vid kassan frågar hon ...
If you started with the subject instead, you would say:
- Hon frågar om vi behöver en påse.
Both are correct, but the first one emphasizes the setting: at the checkout.
