Can’t is a contraction of cannot, and as such it’s sometimes unsuitable for formal writing. In everyday writing and in speaking, it’s ubiquitous:
I can’t go out until I proofread my essay.
Mike can’t believe what’s happening in front of his eyes.
Cannot is better in formal writing:
I cannot wait until Saturday to see the movie.
We cannot allow these people to get in the way.
Don’t use can not when you mean cannot. The only time you’re likely to see can not written as separate words is when the word “can” happens to precede some other phrase that happens to start with “not”:
We can not only break even, but also turn a profit.
The company’s new product can not only reduce emissions, but also trap some of the existing greenhouse gasses.
Here is a quick summary:
- Can’t is a contraction of cannot, and it is best suited for informal writing.
- In formal writing and where contractions are frowned upon, use cannot.
- It is possible to write can not, but you generally find it only as part of some other construction, such as “not only . . . but also.”
