What is the effect of using an imperative verb?
Imperative verbs are used to form commands or restrictions.
Imperative verbs are used when you want to ask someone to do something for example:
Open the window, please. - In this sentence open is a verb used in imperative mood.
If you use negation together with an imperative verb you will get a ban. For example:
Do not park your car here. - this sentence tells that it is forbidden to park in the area. Verb to park is used in imperative mood with negation "do not park".
