How to Form Questions in English

You ask questions every day — in conversation, at work, in shops, in messages. English has seven distinct question types, and each one follows its own word-order rules. This guide covers all of them, from the simplest yes/no questions to tricky indirect questions with prepositions. Every section includes common mistakes to watch for and practice exercises.

Work through the sections in order. By the end, you will be able to form any question correctly and know why each type works the way it does.

How this guide works

Each question type follows the same structure:

1. The rule — a short summary you can scan quickly
2. When you use it — the real-life situations where this type appears
3. Examples — several examples covering different subjects and tenses
4. Practice — interactive exercises to test yourself

Type 1: Yes/No Questions

The rule: Put the auxiliary verb before the subject. The answer is "yes" or "no."

Pattern: Auxiliary + subject + main verb?

When you use it

Any time you want to confirm or deny something: Do you want coffee? Is she coming? Did they finish?

Examples by tense

Tense	Auxiliary	I / you / we / they	he / she / it
Present simple	do / does	Do you like coffee?	Does she work here?
Past simple	did	Did they travel last summer?	Did he call you?
Present continuous	am / is / are	Are you leaving now?	Is he working today?
Past continuous	was / were	Were they waiting for us?	Was she reading?
Present perfect	have / has	Have you finished?	Has he called yet?
Modal (can)	can	Can we sit here?	Can she swim?
Modal (will)	will	Will they come?	Will it rain tomorrow?

Type 2: What / Where / When / Why / How Questions

The rule: Put the question word first, then use the same auxiliary + subject order as yes/no questions. The question word replaces the object (the thing you're asking about).

Pattern: Question word + auxiliary + subject + main verb?

When you use it

When "yes/no" is not enough and you need specific information — a place, a time, a reason, a thing.

Question words at a glance

Question word	Asks about	Example
What	things, actions	What do you want? / What does she study?
Where	places	Where do they live? / Where does he work?
When	time	When did you arrive? / When does the shop open?
Why	reasons	Why are you laughing? / Why did he leave?
How	manner, method	How does it work? / How did you get here?
Who (object)	people	Who did you call? / Who does she like?
How often	frequency	How often do you exercise? / How often does he visit?
What time	specific time	What time does the shop close? / What time do you wake up?
How long	duration	How long did the meeting take? / How long have you waited?

Present tense

The auxiliary is do (I/you/we/they) or does (he/she/it):

• How often do your friends visit you?
• What time does the store close on weekdays?
• Where do they usually eat lunch?
• What does he do for a living?

Past tense

The auxiliary is always did — for all subjects:

• What did you eat for lunch?
• Where did they go after the party?
• What time did the film start?
• What did Charles say about the new project?

Continuous tenses

The auxiliary changes to am/is/are (present) or was/were (past), and the main verb takes -ing:

• Present continuous: What are you reading? / Who is she talking to?
• Past continuous: What was Nancy wearing at the event? / Who were you calling?

Type 3: Subject Questions

The rule: When the question word is the subject (the person or thing doing the action), don't add do/does/did. The verb keeps its normal statement form.

Pattern: Question word + verb (no do/does/did)?

Quick test: Ask yourself — "Am I asking about the doer?" If yes, no auxiliary needed.

When you use it

When you don't know who did something or what caused something: Who called? What happened? Who lives here?

Side-by-side: Subject vs. Object questions

The best way to understand subject questions is to see them next to object questions for the same verb:

Subject question (asking about the doer)	Object question (asking about the receiver)
Who called you?	Who did you call?
What happened?	What did you do?
Who lives here?	Where do you live?
Who wants some coffee?	What do you want?
What causes this problem?	What does smoking cause?

Notice the pattern:

• Subject question: Who/What + verb (no auxiliary) — the verb gets -s for present, -ed for past
• Object question: Who/What + auxiliary + subject + base verb

Subject questions in other tenses

In continuous and perfect tenses, the auxiliary is part of the tense structure, so it stays — even in subject questions:

Tense	Subject question	Why the auxiliary stays
Present continuous	Who is washing the car?	"is" is part of the continuous tense, not do-support
Present perfect	Who has got my car keys?	"has" is part of the perfect tense, not do-support
Past continuous	Who was making that noise?	"was" is part of the continuous tense

Critical warning: After learning "no auxiliary in subject questions," many learners over-apply the rule and say *Who washing the car? or *Who got my keys? — this is wrong. The "no auxiliary" rule only applies to do/does/did. Tense auxiliaries (am/is/are/was/were/have/has) always stay.

Type 4: Negative Questions

The rule: Add n't to the auxiliary. The meaning changes — negative questions express surprise, make suggestions, or confirm expectations.

Pattern: (Question word +) auxiliary + n't + subject + verb?

When you use it

Negative questions are not just "questions with a negative." They have specific communicative purposes:

Purpose	Example	What the speaker really means
Suggestion	Why don't you visit your grandparents more often?	I think you should visit them
Asking about a restriction	Why can't Tom join us for the party tonight?	I expected him to come — what's stopping him?
Surprise	Why isn't the computer working properly?	I expected it to work — something is wrong
Confirming an expectation	Don't you have a brother?	I thought you did — am I right?
Starting a conversation	Isn't it a beautiful day?	I'm making friendly conversation

Examples with different auxiliaries

• Why don't you come with us? / Why don't they try again?
• Why doesn't she answer the phone? / Why doesn't he ever clean up?
• Why can't we go to the park? / Why can't I find my keys?
• Why isn't he at work today? / Why isn't it working?
• Why won't they listen? / Why won't she tell us?
• Why haven't you finished? / Why hasn't he replied?

Type 5: Indirect Questions (Embedded Questions)

The rule: After polite starters like "Do you know…" or "Can you tell me…", use statement word order — subject before verb. No inversion. The auxiliary do/does/did disappears, and the verb takes its normal form.

Pattern: Intro phrase + question word + subject + verb

This is one of the most common mistakes in English — even at intermediate level.

When you use it

When you want to be polite, less direct, or when you embed a question inside a statement:

• Asking a stranger for directions: Do you know where the station is? (not Where is the station?)
• In a meeting: Could you explain how this works? (not How does this work?)
• Thinking aloud: I wonder why they left so early.

How to convert a direct question into an indirect question

Direct question	Indirect question	What changed
Where is the station?	Do you know where the station is?	"is" moved after "station" (statement order)
What time does it start?	Can you tell me what time it starts?	"does" disappeared; verb takes -s
Where did he go?	Do you know where he went?	"did" disappeared; verb takes past form
How do I get to the library?	Can you tell me how to get to the library?	"do I" becomes "to" + base verb
Why are they late?	Do you remember why they are late?	"are" stays but moves after "they"
Do you like coffee?	I was wondering if you like coffee.	yes/no → add "if" or "whether"

Common indirect question starters

Starter	Example
Do you know…?	Do you know where she lives?
Can you tell me…?	Can you tell me what time the train leaves?
Do you remember…?	Do you remember what he said?
I wonder…	I wonder why they left so early.
Could you explain…?	Could you explain how this works?
Do you have any idea…?	Do you have any idea where he went?

Type 6: Narrowing Questions (What kind of / Which / What + noun)

The rule: Add a noun or phrase after the question word to narrow what you're asking about. The rest of the question follows normal word order.

Pattern: (What/Which) + narrowing phrase + auxiliary + subject + verb?

When you use it

When "what" or "which" alone is too broad and you want to specify a category, attribute, or set:

• What do you like? → too open → What kind of music do you like?
• Which have you seen? → unclear → Which of these movies have you seen?
• What is your car? → too vague → What colour is your car?

Common narrowing patterns

Narrowing phrase	What it does	Example
What kind of + noun	asks about a category	What kind of music do you prefer?
What sort of + noun	same as "kind of"	What sort of food does she like?
Which of + set	asks to pick from a group	Which of these movies have you seen?
What + attribute noun	asks about a characteristic	What colour is your car? / What size do you wear?
Which + noun	asks to pick from known options	Which city is bigger? / Which book did you like more?

More examples

• What kind of car did they buy? / What kind of books are you reading?
• Which of the options do you prefer? / Which of your friends did you invite?
• What colour are her eyes? / What language does she teach?
• Which bus goes to the city centre? (subject question — no auxiliary)
• Which team won the match? (subject question — no auxiliary)

What vs. Which: Use "what" when the options are open or unlimited (What colour do you want?). Use "which" when choosing from a known, limited set (Which colour do you want — red or blue?).

Type 7: Questions with Prepositions

The rule: In everyday English, the preposition goes at the end of the question. In formal English, the preposition can go at the beginning (with "whom" instead of "who" for people).

Pattern (everyday): Question word + auxiliary + subject + verb + preposition? Pattern (formal): Preposition + question word + auxiliary + subject + verb?

Both forms are correct. Use the everyday form in conversation and writing. Recognise the formal form when you see it in books or official documents.

When you use it

Many common verbs need prepositions: talk to, look for, come from, go with, buy from, think about. When you turn these into questions, the preposition must go somewhere.

Everyday vs. formal: side by side

Preposition	Everyday (preposition at end)	Formal (preposition at start)
with	Who did you go with?	With whom did you go?
for	What are you looking for?	For what are you looking?
from	Where did she come from?	From where did she come?
to	Who did you speak to?	To whom did you speak?
about	What are they talking about?	About what are they talking?
from (which)	Which store did you buy the dress from?	From which store did you buy the dress?

Putting It All Together: Decision Guide

When you need to ask a question, follow these steps:

Step 1 — What kind of answer do you need?

If you need…	Use this type
A yes or no	Type 1: Yes/No question
Specific information (what, where, when, why, how)	Type 2: What/where/when/why/how question
To know who did something	Type 3: Subject question
To express surprise or suggest something	Type 4: Negative question
To ask politely or embed a question	Type 5: Indirect question
To narrow by category, attribute, or set	Type 6: Narrowing question (what kind of / which / what + noun)
To ask about something involving a preposition	Type 7: Preposition question

Step 2 — Build the question using the pattern for that type.

Step 3 — Check for these common traps:

Trap	How to avoid it
Changing the verb after do/does/did	Keep the base form: Does she like… not Does she likes…
Forgetting to invert	Auxiliary before subject: Are you… not You are…?
Adding do/does/did to subject questions	No auxiliary when asking about the doer: Who called? not Who did call?
Using question order in indirect questions	Statement order after "Do you know": …where it is not …where is it
Splitting verb and preposition	Keep them together: looking for not looking… for
