We use imperative clauses when we want to tell someone to do something (most commonly for advice, suggestions, requests, commands, orders or instructions).
We can use them to tell people to do or not to do things. They usually don’t have a subject – they are addressed to the listener or listeners, who the speaker understands to be the subject. We use the base form of the verb:
Enjoy your meal.
Stop talking and open your books.
For emphasis, we can use you in an imperative clause:
[a student and a teacher]
A: Can I leave the room?
B: No. You stay here.
In negative imperatives of this type, you comes after don’t:
Maria, don’t you try to pay for this. I invited you for lunch and I insist on paying.
We can also use words like someone, somebody, no one, nobody, everyone, everybody, especially in speaking:
Somebody call a doctor. Quick!
Everybody sit down, please.
So, we often form commands with "you", "somebody" or "everybody", etc, for example, "You close the door", "Somebody call a doctor", "Everybody sit down".
But, Could we form commands with "we, he, she, it, they", for example, "we/they do it", "he/she open the door" (no "s" after "open" because it's not the simple present)?
And, could we form negative commands with "you don't", for example, "you don't open the door"?
