Basic order: (question word) + auxiliary + subject + main verb. If there is no auxiliary, use do / does / did.
Where are you going? — What have you done? — Why did she leave? — How long does it take?
Subject questions: when who / what / which is the subject, no do / did and normal order:
| subject question | object question |
|---|---|
| Who called you? (someone called) | Who did you call? (you called someone) |
| What happened? | What did you do? |
Prepositions usually go at the end: Who are you talking to? Where are you from? What is it about?
Indirect questions (more polite) after “Can you tell me…”, “Do you know…”, “I wonder…”: statement order, no do / did.
Where is the station? → Can you tell me where the station is?
What time does it start? → Do you know what time it starts?
Is it open? → I wonder if it's open.
Useful question words: what, which (limited choice), who, whose, where, when, why, how, how much (uncountable), how many (countable), how often, how long, how far, what kind of.
