Assertive to Interrogative

Interrogative sentences are questions and assertive sentences are statements. We are often asked to turn an assertive sentence into interrogative without changing the meaning. In this lesson, you will learn how to transform a statement into a question. 

Types of Questions

There are many types of questions in English but we will need to learn two types of interrogative sentences to change an assertive sentence into interrogative. They are Yes/ No Questions and Wh-questions.


Yes/No Questions

A Yes/ No question always begins with a verb and ends with a question mark. It is called yes/ no question because its answer is yes or no. 

Is he present here?
Can you sing?
Are you angry?
Do they come here?


Wh-Questions

A Wh-question always begins with a wh-word and ends with a question mark. It is called wh-question because it begins with a wh-word. 

What is your name?
How old are you?
Why are you angry?
When did they come here?


Rules of Changing Assertive Sentences to Interrogative 


Rule-1: If the assertive sentence has Be Verb, Modal Verb, or Auxiliary Verb, we put it before the subject to make an interrogative sentence. To keep the meaning unchanged, we make the affirmative statement into a negative question. If the statement is negative, the question will be affirmative.

Assertive: He is a rich man.
Interrogative: Isn’t he a rich man?
Assertive: He was very happy.
Interrogative: Wasn’t he very happy?
Assertive: A tiger can see in the dark.
Interrogative: Can’t a tiger see in the dark?

(e) I can never forget a man like you.


Rule-2: If the assertive sentence is in the present simple tense or simple past tense, (i.e. it  does not have Be Verb, Modal Verb, or Auxiliary Verb), we use do, does, or did before the subject to make an interrogative sentence. 

Assertive: I know how to swim.
Interrogative: Don’t I know how to swim?
Assertive: He comes here every day.
Interrogative: Doesn’t he come here every day?

Assertive: Nobody trusts a liar.
Interrogative: Who trusts a liar?
Assertive: All wish to be happy.
Interrogative: Who don’t wish to be happy?
