Can is a modal verb.

Can is used to express ability or to say that something is possible.

Can is the same for all subjects. We don't add an 'S' in the third person (like other verbs)To form the negative we add "not" after can to form one word: cannot.

We can also contract the negative to form can't. (can't = cannot)Sometimes You can and Can you…? are impersonal and refer to people in general.

You can see many stars at night from here. (= people in general can see many stars)

It doesn't necessarily refer to you but people in general.

You can't run naked in the middle of the street.

Not necessarily saying YOU can't run naked in the middle of the street but in general it is not possible for anyone.
