Yes/No Questions With DO


In English, there are two main types of questions which are;

  • Yes / No Questions
  • Wh – Questions


Yes / No questions are the questions which are answered yes or no.  It means when we are asking yes/no questions, we are expecting the answer, yes or no. 

To form Yes/No questions, we use one of these verbs: auxiliary verbs ( be, do and have ) or modal verbs ( can, may,etc.).

We can not use questions words like what, how, why, who, etc. whilw making Yes/No questions.


Yes / No questions are made, using the verb (am, is, are, was, were, have, had, do, does, did, can, will, should etc.) at the beginning of a sentence. Namely, subject and verb change their position in statement and question.

With An Auxiliary Verb ( “Be” or “Do” or “Have” ) or Modal Verb

With “Do”

The verb “ Do ” has two forms in the presentdo and does

The verb “ Do ” has one form in the pastdid.

Subject Present Form “Do” Past Form “Do”
I, You, We, You, They do did
He, She, It does did


1. If there is no any auxiliary verbs in a sentence, we use “do” as an auxiliary verb. Question form is

Do ( as an auxiliary verb ) + Subject + Main Verb + ….

Sentence Question

She gets up early in mornings. Does she get up early in mornings?

1. In Simple Present Tense, we add the suffix -s or -es at the end of the verbs for the third singular subjects ( He, She, It ) .

On the other hand, we use first forms of the verbs for other subjects ( I, You, We, You, They).

2. Although we add the suffix -s at the end of the verb for the third singular subjects in positive sentences, We remove the suffix -s at the end of the verb in questions and negative sentences  because of being used ‘does’ or  ‘doesn’t’ as an auxiliary verb.

3. In Simple Past Tense, any auxiliary verbs aren’t used in positive sentences like in simple present tense and the second form of the main verb ( V2) is used. ‘ Did or did not’ is used as a auxiliary verb in negative and question sentences and the main verb remains simple ( V1) at this time. In other words, if the verb is in the past tense, we add did and put the main verb in its base form in negative and question sentences.

4. In Simple Past Tense, to change regular verbs into its past tense form, we generally add -d, -ed, or -ied at the end of the verbs according to their last syllable ( such as like–liked, work–worked ). However, for some verbs, we use their irregular forms to make them past form ( such as begin–began, give–gave ).

2. If we want to make a negative yes/no question with “do”, question form is

Do ( do, does, did ) + NOT + Subject + Main Verb + ….

3. When we are replying the question, we can use short or long form for the answer. Answer forms are;

Yes + Subject + Auxiliary Verb  ( + … )

No + Subject + Auxiliary Verb + Not ( + …. )
