Is can't is correct or cann't?

Answer 1

Quote from the Related Link:

"Both cannot and can not are acceptable spellings, but the first is much more usual. You would use can not when the 'not' forms part of another construction such as 'not only'."

Answer 2

The two-word form is never used to mean cannot (lack of ability or permission).

The often-used contraction is can't.

(Technically, there is a distinction between can and may, ability and permission.)

Answer 3

The separate words can not are never used, only "cannot" or its contraction "can't".

Answer 4

The form can't is correct (one n).

Answer 5

cannot or can't
