Do – Does Comparison with the Help of Examples

Do and Does

To make a interrogative in English we normally use Do or Does. It is normally put at the beginning.

Affirmative

You Speak English.

Interrogative

Do you speak English?

You will see that we add do at the beginning of theaffirmative sentence to make it a interrogative.

We use do when the subject is I, you, we  or they.

See it with the help of example,

Affirmative

He speaks English.

Interrogative

Does he speak English?

When the subject he, she or it, we add does at the beginning to make the affirmative sentence an interrogative.

Notice that the letter ‘s’ at the end of verb in the affirmative sentence (because it is in third person) disappears in the interrogative.

We will se the reason why below.

We don’t use do or does in interrogative that have the verb to be or modal verbs (can, must, might, should etc.)

Word order of interrogative with “do” and “does”

The following is the word order to construct a basic interrogative in English using ‘do’ or ‘does’.

The verb that goes here is the base form of the infinitive.
The infinitive without to before the verb. Instead of the infinitive to
have
it is just the have part.

Remember that the infinitive is the verb before it is
conjugated (changed) and it begins with to.

For example, to have, to eat, to go, to live, to speak etc.

Short Answers with Do and Does

In interrogative sentences that use ‘do’ or ‘does’, it is possible to give short answers to direct questions as shown in the following examples.

Question Short Answer
(Affirmative)
Short Answer
(Negative)
Do you speak English? Yes, I do. No, I don’t.
Do I need a dictionary? Yes, you do. No, you don’t.
Do you both speak English? Yes, we do. No, we don’t.
Does he speak English? Yes, he does. No, he doesn’t.
Does it have four legs? Yes, it does. No, it doesn’t.

However, if a question word such as who, when, where,why, which or how is used in the interrogative, you cannot use the shortanswers above to respond to the question.

The order for making sentences with question words is the
following.

Question
Word
+ Do/Does + Subject + Verb

What     +             do           +             you        +             have for breakfast?        

What     +             does      +             she         +             have
for breakfast?

Where  +             do           +             you        +             live?

or doesn’t with all verbs except to be and modal verbs
(can, might, should etc.)

Affirmative

You speak Spanish.

Negative

You don’t speak Spanish.

You will see that we add don’t between the subject
and the verb. We use don’t when the subject is I, you, we or they.

See another example,

Affirmative

He speaks French.

Negative

He doesn’t speak French.

When the subject is he, she or it, we add doesn’t
between the subject and the verb to make a negative sentence. Notice that
the letter ‘s’ at the end of the verb in the affirmative sentence
disappears in the negative sentence.

Contractions

Don’t = Do not

Doesn’t = Does not

I don’t like fish. = I do not like fish.

There is no difference in meaning though we normally use
contractions in spoke English.
