Which one is correct `是不是你想离开` or `你是不是想离开`? I think it is correct to say 是不是想离开 to emphasize whether it is true that you want to leave.
I wonder if I want to add 你, where should it be in the sentence?
是不是你想离开 or 你是不是想离开?
Both 是不是你想离开 and 你是不是想离开 are correct and can mean the same.
However, it's worth to mention that in 是不是你想离开, when you put a tone emphasis on 你 like 是不是'你'想离开, it would mean Is it you that want to leave, implying it's you, not others.
