Questions & Answers about Kan jeg låne boken din?
Because this is a yes/no question. In Norwegian, yes/no questions usually put the verb first:
- Kan jeg låne boken din?
- literally: Can I borrow your book?
In a normal statement, the order would be:
- Jeg kan låne boken din.
- I can borrow your book.
So the change from statement to question is mainly the verb-subject inversion: kan jeg instead of jeg kan.
Kan is the present tense of kunne, and here it means can.
In this sentence, it is being used to make a polite request, similar to English:
- Can I borrow your book?
So it is not only about ability; it is also a common way to ask for permission politely.
