You know where, you, and live, but Where you live? still comes out when you ask for directions. The missing piece is the word that supports the English question: do or a form of be placed in the right position.
Wh- questions ask for information rather than a simple yes or no. Once you can see wh- word + auxiliary + subject + verb, the same pattern becomes useful in travel, work, and everyday conversation.
The common pattern: wh- word + auxiliary + subject + verb
The usual question words are what, where, when, why, who, which, whose, and how. With ordinary verbs in the present or past, do / does / did helps form the question:
- Where do you live?
- When does the meeting start?
- Why did they leave early?
You live in Busan. → Where do you live?
>
She called yesterday. → Why did she call yesterday?
After did, the main verb returns to its base form: Why did she call?, not *Why did she called?*. When asking for new information, these questions normally fall toward the end. Raising every word does not make the structure clearer.
If be or another auxiliary is already there, move that
Do not add do when the statement contains am / is / are / was / were. Put be before the subject instead:
- Where is the station?
- When are you leaving?
- Why was the train delayed?
An existing auxiliary such as can, will, should, or have takes the same position:
- Where should I park?
- What has she decided?
Where is it? ✓ Where it is? ✗
>
What can I do? ✓ What I can do? ✗
Compare Where does it stop? with Where is it?: stop is a main verb and needs does, while is already supplies the structure and needs no do.
When who is the subject, do not add do
Who can refer to the person receiving an action. The sentence then has another subject and follows the usual pattern:
Who did you call? The person you called is the object.
It can also refer to the person doing the action. In that case, who is already the subject:
Who called you?
>
Who owns this bag?
The same reasoning explains What happened?, not *What did happen?* in a neutral question. Ask yourself whether you want to know who performed the action or whom the action affected before reaching for do.
After Could you tell me, return to statement order
A direct question can sound a little abrupt when you approach a stranger or a new colleague. Could you tell me...? and Do you know...? provide a polite frame. The opening is already a question, so the part inside uses subject + verb:
Where is the exit? → Could you tell me where the exit is?
>
What time does it open? → Do you know what time it opens?
>
Is this seat free? → Do you know if this seat is free?
Avoid *Could you tell me where is the exit?*. A yes/no question inside the frame uses if / whether and does not introduce an additional inversion. Politeness also comes from your tone; adding could to every clause is unnecessary.
A two-minute correction drill
Say each prompt as a complete question before checking the answer. Then read the finished sentence aloud:
- where / you / go → Where did you go?
- where / the bathroom / be → Where is the bathroom?
- who / this bag / own → Who owns this bag?
- could you tell me / the shop / open / when → Could you tell me when the shop opens?
On a second round, replace the place with somewhere you actually need to ask about: your hotel, station, or office. With MirrorSay, you can start from a question you want to ask in your own language, compare a natural English version, and practise saying it. To use questions after someone answers, continue with follow-up questions in English.
