Root Explanation

Cannot → It is formed from "can" (from Old English "cunnan", meaning to be able) and "not" (from Old English "nōt", meaning not). The word "cannot" means to be unable to do something, combining the ability to do (can) with the negation (not).

Memory Tip

Think of 'being able' ('can') and then adding 'not' to it — that's why 'cannot' means you are unable to do something.
