An imperative sentence is a command sentence. When we give a command, we order someone to do something. The imperative sentence begins with a verb rather than a subject. The subject is understood to be the person to whom the command is being given. Look at these imperative sentences:
Sit down!
Do not touch that!
Bring the chair over here.
Close the gate so the dog doesn’t get out.
An imperative sentence gives a command. If the command is urgent, use an exclamation mark at the end. Otherwise, just end an imperative sentence with a period.
▶It’s your turn. Decide which of these sentences is an imperative sentence. Bob took a shower. Bring him a towel. Did you say that the second sentence is imperative because it begins with a vowel? Good for you!
