How to Form Questions in English: Rules & Examples

To form questions in English, you often need to change the order of the subject and verb. Sometimes you move a helping verb that’s already in the sentence. Other times, you add do, does, or did.

Compare these two statements and questions:

The parcel has arrived.

Has the parcel arrived?

But:

The parcel arrived yesterday.

Did the parcel arrive yesterday?

In the first question, has moves before the subject. In the second, we add did and use the base form arrive.

The difference depends on the verb structure in the original sentence.

Start with the Verb Before Changing Word Order

When you want to turn a statement into a question, begin by finding its subject and verb phrase.

If there’s already an auxiliary or modal verb, it will usually move before the subject. If there isn’t one, look at the main verb. The verb be can normally move before the subject on its own, while most other simple present and past verbs need do, does, or did.

Consider:

The concert tickets have been booked.

The subject is the concert tickets, and the verb phrase is have been booked. Since the sentence already contains auxiliaries, we move the first one:

Have the concert tickets been booked?

Now compare:

The concert tickets arrived yesterday.

Here, arrived is a simple past main verb without an auxiliary. We add did and use the base form of the main verb:

Did the concert tickets arrive yesterday?

The question is still about a past event, but did now carries the past-tense marking.

How to Turn a Statement into a Question

The verb tells you which question pattern to use. Sometimes changing the word order is enough. In other cases, you need an additional auxiliary.

When the Main Verb Is Be

The verb be has several forms, including am, is, are, was, and were.

When be is the main verb, place it before the subject.

The entrance is beside the ticket office.

Is the entrance beside the ticket office?

Past-tense forms of be work this way too:

The streets were quiet after midnight.

Were the streets quiet after midnight?

You don’t need do, does, or did for these questions.

You can also see this pattern in sentences with there is and there are:

There are three empty seats near the window.

Are there three empty seats near the window?

There was a spare blanket in the cupboard.

Was there a spare blanket in the cupboard?

In questions such as Are there any empty seats?, be comes before there. You don’t need do to form the question.

When the Sentence Already Has an Auxiliary or Modal

If a statement contains an auxiliary or modal, move it before the subject.

The children are rehearsing for the school play.

Are the children rehearsing for the school play?

With a modal verb:

Visitors can enter through the side gate.

Can visitors enter through the side gate?

You can also ask questions with should, would, and could:

Should we take a different route?

Would a later appointment be more convenient?

Could the missing photographs still be recovered?

There’s no need to add do before an existing modal.

Incorrect: Do visitors can enter through the side gate?

Correct: Can visitors enter through the side gate?

Modal verbs such as can, should, and will are followed by the base form of a verb, which may itself be an auxiliary.

When You Need Do, Does, or Did

Some statements contain an ordinary main verb without an auxiliary.

Consider:

The bakery delivers fresh bread every morning.

There’s no auxiliary to move, so we add does:

Does the bakery deliver fresh bread every morning?

Notice that delivers becomes deliver. The auxiliary does already carries the present-tense agreement.

Use:

• Do with I, you, we, they, and plural subjects.
• Does with he, she, it, and singular third-person subjects.
• Did for ordinary simple past questions, regardless of the subject.

For example:

The passengers need printed tickets.

Do the passengers need printed tickets?

In the past tense:

The train stopped at the smaller station.

Did the train stop at the smaller station?

After do, does, or did, the main verb takes its base form.

Incorrect: Does the manager approves the request?

Correct: Does the manager approve the request?

Incorrect: Did the driver took the wrong exit?

Correct: Did the driver take the wrong exit?

This also applies when do itself is the main verb:

My brother does the grocery shopping on Sundays.

Does my brother do the grocery shopping on Sundays?

The first does in the question is the auxiliary. The second do is the main verb.

When Have Is the Main Verb, an Auxiliary, or Part of Have To

The verb have deserves a closer look because the same form can do different jobs in a sentence.

In the first and third statements, have is the main verb or part of have to, so the questions use does. In the other two, has is an auxiliary and moves before the subject.

The difference becomes clear with had, too.

The visitors had enough time to finish the tour.

Did the visitors have enough time to finish the tour?

But:

The visitors had already left.

Had the visitors already left?

In the first pair, have is the main verb. In the second, had forms the past perfect.

For possession, particularly in British English, you may also hear:

She has got a passport.

Has she got a passport?

This is another standard construction, although usage varies by region.

In contemporary English, do/does/did + have is a reliable everyday pattern for questions where have is the main verb.

You can explore these distinctions further in the verb to have.

When There Is More Than One Auxiliary

A sentence may contain two or more auxiliaries. In an ordinary direct question, only the first auxiliary moves before the subject.

The road has been closed since dawn.

Has the road been closed since dawn?

The remaining verbs keep their original order.

Consider a longer verb phrase:

The new playground will have been completed by June.

Will the new playground have been completed by June?

Incorrect: Will have the new playground been completed by June?

Correct: Will the new playground have been completed by June?

You can see this with there have been, too:

There have been several changes to the timetable.

Have there been several changes to the timetable?

Here, have moves before there, while been stays in place.

Questions Across Common Tenses and Verb Patterns

Adding a Question Word

You can ask whether something is true or request a particular detail using a question word such as who, what, where, when, why, or how.

Consider:

The parcel was delivered on Tuesday.

To confirm the information:

Was the parcel delivered on Tuesday?

To ask about the delivery day:

When was the parcel delivered?

The word when replaces the time information, while was still comes before the subject.

Another example:

The courier left the package at reception.

You can ask:

Did the courier leave the package at reception?

Or, if the location is unknown:

Where did the courier leave the package?

For many WH questions, the pattern is:

Question word or phrase + auxiliary verb + subject + main verb

Longer question phrases work the same way:

How many tickets did the visitors purchase?

Which department will handle the complaint?

For more detail on choosing question words, see WH Questions in English.

Forming Negative Questions

Negative questions use not or contractions such as don’t, doesn’t, didn’t, isn’t, haven’t, and can’t.

Compare:

Did the supplier respond?

Didn’t the supplier respond?

With a contraction, n’t attaches to the auxiliary before the subject.

Without a contraction, not normally comes after the subject:

Did the customer not receive the confirmation?

Didn’t the customer receive the confirmation?

Both forms are grammatical, although contractions are common in everyday conversation.

The same distinction appears in WH questions:

Why did the library not open on time?

Why didn’t the library open on time?

The second usually sounds more conversational. The first may be used for emphasis or in a more formal context.

Negative questions can also express surprise or an expectation about the answer, depending on the situation.

When the Usual Question Pattern Changes

Most questions involve moving an auxiliary or adding do, does, or did. Two common constructions work differently.

When the Question Word Is the Subject

Consider:

Nora contacted the venue.

If you want to know who contacted it:

Who contacted the venue?

Here, who replaces the subject Nora. You don’t normally add did merely to form this neutral question.

Now suppose you want to know who Nora contacted:

Who did Nora contact?

Here, who is the object, so the ordinary did pattern applies.

Subject questions can still contain auxiliaries when required by tense or negation:

Who has approved the final design?

Who didn’t receive the updated instructions?

This doesn’t mean subject questions can never contain auxiliaries. The point is that they don’t normally require do-support simply because they’re questions.

When a Question Is Embedded in Another Sentence

A direct question can become part of a longer sentence.

Direct question:

Where did the staff store the spare key?

Question containing an embedded question:

Could you tell me where the staff stored the spare key?

The embedded part uses statement word order.

Correct: Do you know when the delivery will arrive?

Incorrect: Do you know when will the delivery arrive?

An embedded question can also appear in a statement:

Nobody remembers where the spare key was stored.

This sentence ends with a period because it’s declarative. Could you tell me where the staff stored the spare key? ends with a question mark because the main clause asks a question.

Practice: Identify, Form, and Correct Questions

These exercises will help you recognize the verb pattern, form the correct question, and identify grammatical errors.

Exercise 1: Identify the Rule and Form the Question

For each statement, decide whether you need to move the main verb be, move an existing auxiliary or modal, or add do, does, or did. Then write the yes/no question.

1. She has a new laptop.
2. She has repaired her laptop.
3. She has been repairing her laptop.
4. There are two available seats.
5. The manager has to approve the refund.
6. The parcel arrived yesterday.

Exercise 2: Ask for the Missing Information

Rewrite each statement as a WH question that asks about the specified detail.

1. The gallery closes at five.
   Ask about the closing time.
2. A power cut interrupted the livestream.
   Ask what interrupted the livestream.
3. The caretaker left the keys in the office.
   Ask where the keys were left.
4. The replacement package was forwarded on Monday.
   Ask when it was forwarded.
5. The manager postponed the training because the instructor was unavailable.
   Ask for the reason.

Exercise 3: Find and Explain the Error

Each question contains a grammatical error. Rewrite it correctly and identify what went wrong.

1. Does the customer has a refund request?
2. Does Maya works on Sundays?
3. Has been the parcel delivered?
4. Do visitors can enter after six?
5. Where the invoices are stored?
6. Could you tell me what does this switch control?

Answers and Explanations

Exercise 1

Exercise 2

1. What time does the gallery close?
2. What interrupted the livestream?
3. Where did the caretaker leave the keys?
4. When was the replacement package forwarded?
5. Why did the manager postpone the training?

The second answer is a subject question, so ordinary do-support is unnecessary. The other questions follow the appropriate verb patterns.

Exercise 3

1. Does the customer have a refund request?
   Use the base verb have after does.
2. Does Maya work on Sundays?
   The simple present auxiliary does takes the base verb work.
3. Has the parcel been delivered?
   Only the first auxiliary moves before the subject.
4. Can visitors enter after six?
   Don’t add do before the modal can.
5. Where are the bicycles kept?
   In a direct question, are comes before the subject.
6. Could you tell me what this switch controls?
   The embedded question uses statement word order, with this switch before controls.
