no and not

If we want to make a word, expression or clause negative, we use not.

    Not surprisingly, we missed the train.
    The students went on strike, but not the teachers.
    i can see you tomorrow, but not on Thursday I have not received his answer.

We can use no with a noun to mean ‘not a’ or ‘not any’.

    No teachers went on strike. ( = There were not any teachers on strike.)
    I’ve got no Thursdays free this term. (= . . . not any Thursdays . . .)
    I telephoned, but there was no answer ( = . . . notan answer.)

Sometimes verb + not and no + noun can give a similar meaning.

    We can use no with an -ing form.
