The imperative mood expresses an order or command. We use it to address one or more people directly. It is formed with the base or infinitive form of a verb and is generally used without a subject.
We use the imperative to order someone to do or not to do something.
We use the basic form of the verb without to, to form the imperative in English grammar.
To order someone not to do something, we use do + not before the verb. Most of the time we use the contraction don’t.
