Assertive & Interrogative Sentence

Before starting our discussion on transformation rules of seertive to interrogative we should learn the basic definition and structure of both assertive sentence and interrogative sentence.

What is Assertive Sentence?

Assertive sentence means the sentences which are used to describe any general action, event, speech, or expression of our daily life. It may be both in affirmative (positive sense) and negative (negative sense) form. So, both affirmative and negative sentences are categorized under assertive sentence.



  • Affirmative: Subject+ verb+ object+ Adjunct
  • Negative: Subject+ do not/ does not/ did not/ verb+ object+ Adjunct

I told him to stay here till I come back.
We do not take old clothes for our business.

What is Interrogative Sentence?

Interrogative sentence means the sentences which are used to ask or inquiry about any daily acts, events, or speeches of our daily life. Here is the structure of it.

Structure: WH-Q/Auxiliary verb+ subject+ main verb+ object?

Do you study in this college?
When do they play here?


Please note that here in interrogative sentence, the sentence starts with either a WH-Question: (who/ what/ which/ when/ why/ where/ when) or an auxiliary verb: (do/ does/ did/ am/ is/ are/ was/ were/ can/ may/ shall/ will) and after that the subject comes. This is completely different in case of the assertive sentence where a sentence starts with a subject.

But, in case of an interrogative sentence, it will always start with a WH-Question word or an auxiliary verb and there will be a question mark “?” at the end of the sentence.

Now, I hope you have no problem in identifying both assertive sentences and interrogative sentences in English language. So, let’s start our main discussion…

Assertive to Interrogative Rules

Most of the English grammar books have a lot of rules on changing assertive/ affirmative to interrogative sentences but the major problem for a student is to read a lot of rules in number and getting confused in memorizing them and applying them during exams. So, i have shortened and categorized all of those rules into only 5 rules. It will help you learn transformation process easily and effectively without any confusion.

A Few Points You Must Consider:

  • You cannot change the meaning of sentences while changing assertive to interrogative.

  • If the assertive sentence is in affirmative or positive, you have to use negative expression in interrogative structure and if it is in negative, you will use the affirmative or positive expression in interrogative structure while transformation of sentences.

  • An interrogative sentence may start with either a wh-question or a verbal question.

  • Do not forget to use the interrogation mark (?) at the last of the sentence in interrogative structure.

  • During transforming into interrogative sentence, you have to use the auxiliary verb according to the tense. For an example, in present indefinite tense, the auxiliary verbs will be ‘do/does’. In past indefinite tense, it should be ‘did’. And in case of all other tenses, the auxiliary verb will be given in the question sentence. You have to just re-write that in answer sentence.

Here is the list/ chart of the transformation of sentences assertive to interrogative. The most interesting fact of this chart is that in some cases, you can also change sentences even without understanding the meaning of the whole sentences.

Because, you don’t need to change all elements of a sentence during transformation. All you need is to change a few words/phrases which are listed in the chart given below.
