The imperative mood is used to tell somebody to do something.
Imperative sentences can be used to:
| 
			 give warnings  | 
			
			 give advice  | 
			
			 give orders  | 
		
| 
			 give instructions  | 
			
			 place an order  | 
			
			 make requests  | 
		
Give warnings
Give advice
Give orders
Give instructions
Place an order*
*The word please can be added at the beginning or at the end of an imperative sentence to add politeness.
Make requests*
*Imperative sentences can replace interrogative sentences (questions used to make requests).
To recognize imperative sentences, look for three specific elements:
- 
	
The subject is not mentioned, it is implied.
 - 
	
The implied subject is always you.
 
- 
	
The verb is always in its base form (infinitive without the “to”).
 
Imperative sentences:
- 
	
usually end with a period.
 - 
	
can end with an exclamation mark to express urgency or emotion.
 
| 
			 Sentence Type  | 
			
			 Example  | 
		
| 
			 Declarative  | 
			
			 Everyday, you wash your hands before dinner.  | 
		
| 
			 Interrogative  | 
			
			 Could you wash your hands before dinner?  | 
		
| 
			 Exclamative  | 
			
			 You must wash your hands before dinner!  | 
		
| 
			 Imperative  | 
			
			 Wash your hands before dinner.  | 
		
Points to remember when forming affirmative imperative sentences:
- 
	
Use the base form of the verb.
 - 
	
Place the object*.
 
*The object is not always necessary.
Points to remember when forming negative imperative sentences:
- 
	
Use the negative form do not or don’t.
 - 
	
Use the base form of the verb.
 - 
	
Place the object*.
 
To indicate the way an action should be done: add an adverb.
Although the subject of imperative sentences is an implied second person, subjects can be specified as a way to clarify who is addressed or to get that person’s attention.
| 
			 Addressed to:  | 
			
			 Imperative sentence:  | 
		
| 
			 Mom,  | 
			
			 look at me when I am talking to you.  | 
		
| 
			 Somebody  | 
			
			 get the door!  | 
		
| 
			 Okay Google,  | 
			
			 start a timer.  | 
		
The imperative form is often used to make unreal commands: Sentences that are structured like commands, but that mean to suggest something or express what we wish for someone.
| 
			 Function  | 
			
			 Example  | 
			
			 Explanation  | 
		
| 
			 Suggestion  | 
			
			 If you don’t eat meat, choose the vegan macaroni.  | 
			
			 Offering a suggestion, not an obligation.  | 
		
| 
			 Wish  | 
			
			 Don’t panic! Everything will be fine.  | 
			
			 Wishing the person would not panic.  | 
		
| 
			 Wish  | 
			
			 Feel better!  | 
			
			 Wishing the person would feel better.  | 
		
Imperative sentences are usually written in the active voice. However, in rare cases, to add formality, it is possible to make passive imperatives.
Passive imperatives with the form: Let + object + be + past participle
| 
			 Active  | 
			
			 Passive  | 
		
| 
			 Bring your suitcase to your room.  | 
			
			 Let your suitcase be brought to your room.  | 
		
| 
			 Celebrate Christmas at my home.  | 
			
			 Let the Christmas be celebrated at my home.  | 
		
The words let’s can be added to the beginning of an bsentence to form affirmative or negative suggestions which include ourselves:
Let’s is the contraction of let us, which implies that the subject is the 1st person plural we (you and me).
| 
			 Let’s go to the planetarium.  | 
		
| 
			 Let’s not go our own ways. Let’s stick together.  | 
		
| 
			 Let’s spend a week in Florida.  | 
		
Adding the word do before an imperative sentence adds emphasis, politeness and formality to the command.
| 
			 Request  | 
			
			 Do wait for your turn to speak.  | 
		
| 
			 Complaint  | 
			
			 Do turn down the volume of your tablet. I can’t sleep.  | 
		
| 
			 Apology  | 
			
			 Do forgive me for my tone. I know I was wrong.  | 
		
Tag questions can be added to imperative sentences to add politeness or insistence to the request.
Tag questions are either formed with an affirmative statement and a negative tag question or a negative statement and an affirmative tag question.
However, to express a different intention, it is possible to use an affirmative imperative sentence followed by an affirmative tag question.
| 
			 Example  | 
			
			 Structure  | 
			
			 Intention  | 
		
| 
			 Sit in the waiting room, will you?  | 
			
			 affirmative-affirmative  | 
			
			 To politely invite the person to sit in the waiting room.  | 
		
| 
			 Sit in the waiting room, won’t you?  | 
			
			 affirmative-negative  | 
			
			 To strongly insist that the person sits in the waiting room.  | 
		
A conditional if-clause can replace an imperative clause.
The if-clause uses a comma ( , ).
The imperative uses the word and.
