Explanation:
We use the imperative form to give orders, instructions, or to warn someone about something. To write sentences in the imperative form, we have to write the verb in the infinitive, and if it is a negative command, we have to write the do not or don't and the verb in the infinitive.
For example, if we want to give an instruction, we can say -Turn on the right- the verb is in the infinite form, the subject may or may not be present since the person can deduce to whom we are saying the command. An example of a sentence where we use the negative form can be - Don't run in the hallways- In this case, we use the auxiliary verb do and the auxiliary not followed by the verb.
