Questions & Answers about Kan du ställa saften på bordet?
Kan du literally means Can you.
In Swedish, this is a very common way to make a request, just like in English:
- Kan du öppna fönstret? = Can you open the window?
- Kan du hjälpa mig? = Can you help me?
So in this sentence, Kan du is not really asking about ability in a strict sense. It is functioning as a polite request.
It is usually perfectly normal and polite in everyday Swedish.
Swedish often sounds more direct than English, but that does not automatically make it rude. Kan du ställa saften på bordet? is a natural everyday request.
If you want to sound softer or more formal, you could say things like:
- Kan du vara snäll och ställa saften på bordet? = Can you please put the juice on the table?
- Skulle du kunna ställa saften på bordet? = Could you put the juice on the table?
So Kan du ... ? is standard and polite enough in most situations.
