What type of word is can’t?

Can’t is a contraction. It is the contraction of “cannot” (i.e., the negative form of the modal verb “can”).

Other commonly used contractions include “I’m,” “we’ve,” and “mustn’t.”

These short forms are very common in everyday speech, but they are generally avoided in formal writing (e.g., academic writing).

It’s important to note that “cannot” is not a contraction, and cannot and can not are not interchangeable. The correct negative form of “can” is “cannot” (written as one word).
