Also known as the imperative form, commands are very easy to use. Begin the sentence with a verb and end with an object, a person or a thing.
Tell someone to do something:
* Answer the phone, please.
* Drive to the post office.
* Help me find this information.
The subject in each of these sentences is “you,” but it doesn’t sound correct to use the subject.
* You answer the phone, please. * You drive to the post office. * You help me.
Tell someone not to do something:
* Don’t do that. (The subject is “you.”)
* Don’t hit him.
* Don’t drive a car without a seat belt.
In each sentence above, the present tense is used and the subject is “you.
The polite form of a command uses the word “please.”
* Please give that to me.
* Pass the potatoes, please. (Use the word “pass” when you sit at a table with other people and eat food.)
If someone doesn’t do what you wanted him or her to do, use the word “tell.” For examples, click here.
