Indirect questions are polite or softer versions of direct questions. Instead of asking directly, we embed the question inside an introductory phrase: Do you know…, Could you tell me…, I wonder…
Direct vs Indirect Word Order
The key change: the embedded question uses statement word order, not question word order.
| Direct question | Indirect question | | ---------------------- | ------------------------------------------- | | Where is the station? | Could you tell me where the station is? | | What time is it? | Do you know what time it is? | | Does she speak French? | I wonder if she speaks French. |
Notice: the subject comes before the verb in the embedded part (the station is, it is, she speaks).
Structure
Introductory phrase + question word (if/whether) + subject + verb
| Introductory phrase | Question word | Subject | Verb (rest) | | ------------------- | ------------- | ----------- | ------------- | | Do you know | where | the station | is? | | Could you tell me | what | this | costs? | | I wonder | if | she | is available. | | Can you explain | how | this | works? |
Yes/No Questions Become If or Whether
When the direct question has no question word (yes/no answer), use if or whether.
Direct: Is she coming? Indirect: Do you know if she is coming? Indirect: I wonder whether she is coming.
Whether is slightly more formal and can be used with or not:
I wonder whether or not she is coming.
Common Introductory Phrases
| Phrase | Formality | Example | | ---------------------------- | ------------------- | -------------------------------------------------- | | Do you know... | neutral | Do you know where the meeting is? | | Could you tell me... | polite | Could you tell me when it starts? | | I wonder... | polite / thoughtful | I wonder why he left early. | | Do you have any idea... | neutral | Do you have any idea who that is? | | Would you mind telling me... | very polite | Would you mind telling me how much this costs? | | I'd like to know... | formal | I'd like to know what your plans are. |
Tense Consistency
The tense in the embedded question follows the normal tense rules. If the introductory verb is past tense, shift accordingly.
Direct: Where is the bank? Indirect (present): Can you tell me where the bank is? Indirect (past): I asked him where the bank was.
Common Mistakes
- Keeping question word order: ~~Do you know where is the station?~~ → Do you know where the station is?
- Using do/does/did in the embedded part: ~~Could you tell me where does she live?~~ → Could you tell me where she lives?
- Forgetting if/whether for yes/no questions: ~~I wonder is she coming.~~ → I wonder if she is coming.
- Using if in negative indirect questions: Do you know if he is not coming? — use whether instead if adding or not.
