Question Formation
Learn the different ways a question can be built in English—and discover the four main patterns you can explore in greater detail.
Start with the main idea
A question can be built in more than one way.
Question formation covers the different patterns English uses to build a question. Depending on what is being asked, and how directly, a question can move an auxiliary verb, begin with a question word, attach a short tag, or sit inside a larger sentence.
Did she call?, Where did she go?, She called, didn’t she? and Do you know where she went? all ask about the same event, yet each one is built differently.
This page begins with the broad idea of how questions are formed. Once that foundation is clear, you can explore each of the four patterns in more detail.
The four patterns
Every question follows one of four common patterns.
Each pattern is built differently, and each one suits a different kind of question.
Yes/no questions ask for confirmation.
Did she call?
An auxiliary verb moves before the subject, and the answer can be a simple yes or no.
Wh- questions ask for specific information.
Where did she go?
A question word opens the sentence, asking for a person, place, time, reason or manner.
Question tags turn a statement into a check.
She called, didn’t she?
A short tag is added to the end of a statement, asking the listener to confirm or agree.
Indirect questions ask more politely.
Do you know where she went?
The question is placed inside a larger sentence, softening the request for information.
A common thread
Most patterns depend on where the auxiliary verb sits.
For now, focus on noticing where the auxiliary verb moves, rather than memorising every rule.
Before the subject, in a direct question.
Did she call?
Yes/no and most wh- questions move the auxiliary verb in front of the subject.
After the subject, inside the tag.
She called, didn’t she?
The main statement keeps its normal word order; only the short tag at the end has its own inversion.
Not inverted at all, inside an indirect question.
Do you know where she went?
Once a question is embedded inside another sentence, the subject and verb return to statement order.
Choosing a pattern
The situation decides which pattern fits best.
No single test picks the right pattern every time. Consider what is being asked, and how directly it needs to be asked.
01
Would a simple yes or no answer the question?
A yes/no question is usually the more direct choice.
02
Is a specific detail being asked for?
A wh- question opens with the word that matches the missing detail.
03
Is something being confirmed, rather than asked from scratch?
A question tag checks a belief the speaker already holds.
04
Does the situation call for a softer tone?
An indirect question is often used to sound more polite or less abrupt.

Explore each question pattern in detail.
Everything you’ve learned so far explains how questions are formed in general. The topics below each explore one pattern in much more detail. Choose any lesson that matches what you want to learn next.
Yes/No Questions
Learn how an auxiliary verb moves before the subject to form a question that can be answered with yes or no.
Example: Did she call?
WH- Questions
See how a question word opens the sentence to ask for a specific person, place, time, reason or manner.
Example: Where did she go?
Question Tags
Discover how a short tag added to a statement checks whether the listener agrees or already knows the answer.
Example: She called, didn’t she?
Indirect Questions
Learn how placing a question inside a larger sentence softens the request and changes the word order.
Example: Do you know where she went?
Building your understanding
The same underlying question can be asked in several ways.
The four patterns above are not always separate choices. The same piece of missing information can move between patterns depending on how direct or formal the question needs to be.
The same missing information, asked four ways
Each version below is asking whether the same event happened, but the pattern changes the tone of the question.
Examples
Did she call? — Yes/No, direct and neutral.
Why did she call? — WH-, asking for a reason.
She called, didn’t she? — Tag, checking something already believed.
Do you know if she called? — Indirect, softer and more polite.
Remember
As you work through the individual lessons, you’ll discover that each pattern highlights one way of asking. The individual lessons explain how to build each pattern correctly, and when one pattern suits a situation better than another.
