WH- Questions in English: Meaning, Structure, Rules, and Examples

If you want to ask better questions in English, you need to master WH- questions in English. These are the questions we use to ask for information, not just a yes or no answer. They are essential in everyday conversation, in writing, and in exams such as B2 First (FCE) and C1 Advanced (CAE).

In this lesson, you will learn what WH- questions in English are, how to form them correctly, which question words to use, and what common mistakes to avoid. You will also see lots of clear example sentences and a short practice section at the end.

By the time you finish this lesson, you will feel much more confident asking and answering questions naturally in English.

What are WH- questions in English?

WH- questions in English are questions that usually begin with one of these words:

• what
• where
• when
• who
• whose
• which
• why

We also usually include how in this group, even though it does not begin with wh-. English, in its usual charming way, likes one exception just to keep us humble.

We use these question words to ask for specific information.

Compare these two questions:

• Do you like coffee?
• What do you like to drink in the morning?

The first is a yes/no question.

The second is a WH-question, because it asks for real information.

Why are WH- questions important?

Learning WH- questions in English helps you:

• ask for information clearly
• speak more naturally
• keep conversations going
• understand native speakers more easily
• improve your grammar accuracy
• do better in English exams

Without WH- questions, communication becomes very limited. You can answer yes or no, but you cannot explore ideas, ask for details, or have a proper conversation.

The basic structure of WH- questions

In most cases, the structure is:

WH-word + auxiliary verb + subject + main verb

Examples:

• Where do you live?
• What did she say?
• Why are they laughing?
• When will he arrive?

Let’s look at one example more closely:

Where do you work?

• Where = question word
• do = auxiliary verb
• you = subject
• work = main verb

This is the most common pattern for many WH- questions in English.

The most common WH- question words

1. What

We use what to ask about things, actions, information, or ideas.

Examples:

• What is your name?
• What do you do at weekends?
• What happened yesterday?
• What are you reading?

We also use it in common combinations such as:

• What time is it?
• What colour is your car?
• What kind of books do you enjoy?

2. Where

We use where to ask about place or location.

Examples:

• Where do you live?
• Where is my phone?
• Where did they go after dinner?
• Where are we meeting?

This is one of the most useful question words in everyday English because people are always going somewhere, coming from somewhere, or misplacing something.

3. When

We use when to ask about time.

Examples:

• When does the lesson start?
• When did you last see her?
• When are they coming?
• When should I call you?

You can use when to ask about a specific moment or a general time.

4. Who

We use who to ask about people.

Examples:

• Who is that woman?
• Who do you work with?
• Who called you last night?
• Who are they waiting for?

This word is especially important because it can ask about either the subject or the object of the sentence. We will look at that a little later.

5. Whose

We use whose to ask about possession.

Examples:

• Whose coat is this?
• Whose keys are these?
• Whose idea was it?
• Whose turn is it?

This is a very practical word for everyday life, especially if you live in a busy house where nobody admits ownership of the mysterious socks on the chair.

6. Which

We use which when there is a limited choice.

Examples:

• Which dress do you prefer?
• Which bus goes to the city centre?
• Which option sounds better?
• Which of these books have you read?

Compare:

• What book are you reading?
• Which book are you reading?

What is more open.

Which suggests a choice from a known group.

7. Why

We use why to ask for a reason.

Examples:

• Why are you upset?
• Why did he leave early?
• Why do people learn English?
• Why has she changed her mind?

The answer often begins with because.

• Why were you late?
  Because the bus broke down.

8. How

Although how does not begin with wh-, it is usually taught together with WH- questions in English.

We use how to ask about manner, condition, quantity, degree, frequency, distance, and more.

Examples:

• How are you?
• How does this machine work?
• How old is your brother?
• How much does it cost?
• How many students are there in the class?
• How often do you revise vocabulary?
• How far is the station?

How to form WH- questions in different tenses

Present simple

Use do or does.

Examples:

• Where do you work?
• What does she want?
• Why do they always argue?

Past simple

Use did.

Examples:

• When did you arrive?
• Why did he apologise?
• What did they decide?

Remember: after did, the verb stays in the base form.

• ✅ Where did she go?
• ❌ Where did she went?

That second version is a very common mistake.

Present continuous

Use am / is / are.

Examples:

• What are you doing?
• Why is he shouting?
• Where are they staying?

Present perfect

Use have / has.

Examples:

• What have you done?
• Where has she gone?
• Why have they left already?

Modal verbs

Use the modal verb before the subject.

Examples:

• What can I do to help?
• Where should we sit?
• Why must you leave now?
• How would they react?

Subject questions and object questions

This is one of the most important grammar points when learning WH- questions in English.

Subject questions

When the question word is the subject, we do not use do, does, or did.

Examples:

• Who called you?
• What happened?
• Which student won the prize?

In these examples, the question word is doing the action.

Object questions

When the question word is the object, we usually use an auxiliary verb.

Examples:

• Who did you call?
• What did she buy?
• Which student did the teacher praise?

Compare:

• Who broke the window?
• Who did you see?

The first asks about the person who did the action.

The second asks about the person who received the action.

WH- questions with prepositions

In natural spoken English, prepositions often come at the end of the question.

Examples:

• Who are you talking to?
• What are you looking for?
• Where does she come from?
• Who did you go with?

These are completely natural and correct.

More formal versions are possible:

• To whom are you talking?
• For what are you looking?

However, these sound very formal and sometimes rather stiff in everyday English. Fine for formal writing, perhaps, but not exactly the language of a relaxed chat over a cup of tea.

Indirect WH- questions

We often use indirect questions to sound more polite.

Compare:

• Where is the bank?
• Could you tell me where the bank is?

Notice the word order. In indirect questions, we do not use normal question order after the opening phrase.

• ✅ Could you tell me where she lives?
• ❌ Could you tell me where does she live?

More examples:

• Do you know what time it is?
• Can you tell me why he left?
• I wonder where they went.
• Could you explain how this works?

Indirect questions are very useful in polite conversation, formal writing, and Cambridge speaking tasks.

Common mistakes with WH- questions in English

Here are some of the most frequent errors learners make.

1. Wrong word order

• ❌ Where you are going?
• ✅ Where are you going?

2. Using did with a past verb

• ❌ What did she said?
• ✅ What did she say?

3. Forgetting the auxiliary verb

• ❌ What you want?
• ✅ What do you want?

4. Using do/does/did in subject questions

• ❌ Who did call you?
• ✅ Who called you?

5. Wrong word order in indirect questions

• ❌ Can you tell me where is he?
• ✅ Can you tell me where he is?

These mistakes are common, but the good news is that they become much easier to avoid once you understand the patterns.

Everyday WH- questions you should know

Here are some useful WH- questions in English that you will hear and use often:

• What do you mean?
• Where are you from?
• What’s going on?
• Why not?
• How come?
• Who knows?
• What sort of films do you like?
• How often do you practise English?

Try learning these as whole chunks rather than as separate words. That will help your English sound more natural.

WH- questions for Cambridge exams

If you are preparing for B2 First (FCE) or C1 Advanced (CAE), WH- questions are especially useful in:

• speaking tasks
• interviews
• collaborative tasks
• informal emails
• stories and dialogues
• articles with a conversational style

Being able to ask good questions helps you sound interactive, fluent, and engaged. In the speaking exam, this can make a very positive impression.

For example:

• What do you think about this idea?
• Why do you think people enjoy learning English through films?
• Which option would be better for students?
• How can we improve this situation?

These question forms are simple, but they are powerful.

Final thoughts

WH- questions are one of the foundations of clear and natural communication. Once you understand how they work, you can ask better questions, understand conversations more easily, and speak with much more confidence.

The best way to improve is to notice these questions in real English, then start using them yourself. Listen for them in podcasts, films, interviews, and everyday conversations. Then practise making your own examples.

Little by little, these structures will become second nature.
