"Can't you...?" and "Can you not...?"
As a non-native English speaker, I have always understood that in negative questions and in negative imperatives, the auxiliary (or the verb) always goes before the subject, instead "not" goes before the subject only when contracted:
Don't you dare! == Do you not dare!
Don't you speak it? == Do you not speak it?
Aren't you from there? == Are you not from there?
In these examples the two versions of the same sentences have the same meanings.
However, I noticed that with the auxiliary "can", changing the position of "not" completely flips the meaning of the sentence.
Can't you move it? = Asking if you are not able to move it or suggesting you to move it
Can you not move it? = Asking you to not move it
Why does this happen with "can" but not with "do"? Am I missing something? Or can both of them actually mean both the things?
