Kille is used almost as much as pojke in modern Swedish. Kille is considered a bit more casual.

In what ways does kille differ from pojke in terms of usage, context etc?

When it is used 'ni' and when 'du' for you?

This is so weird. I was in the middle of doing a practice Swedish lesson, and all of the sudden, about half way through, the words turned to Danish! It made me translate "You are a boy" to "Du er en deng". But in the comments it turned back to swedish. I'm so confused!

would "dig" be used if "you" was the object? (e.g. i love you)
