An indirect question is a question embedded inside a polite phrase or statement. Instead of asking directly — Where is the station? — you embed it: Could you tell me where the station is? Indirect questions sound softer and more formal, and, as the Cambridge Grammar notes, they are essential for professional communication, polite requests and academic writing.
What Are Indirect Questions?
Indirect questions (also called embedded questions) are questions placed inside another clause. They are used to ask for information more politely, to introduce uncertainty, or to soften a request. The key grammar change is that the word order reverts to normal subject-verb order, and auxiliary verbs like do/does/did are dropped.
Formation Rule
Introductory phrase + question word + normal subject-verb order (no inversion, no do/does/did)
- Direct: Where is the station? → Indirect: Could you tell me where the station is?
- Direct: What does she want? → Indirect: Do you know what she wants?
- Direct: When does the train leave? → Indirect: I was wondering when the train leaves.
Common Introductory Phrases
- Polite requests: Could you tell me…? Would you mind telling me…? Can you explain…?
- Statements: I was wondering… I'd like to know… I'm not sure… Do you happen to know…?
- Formal/academic: I wonder… The question is… It is not clear…
Yes/No Questions — Use if/whether
When the original direct question is a yes/no question (no question word), use if or whether to introduce the indirect question:
- Direct: Is she coming? → Do you know if she is coming?
- Direct: Has he arrived? → Could you tell me whether he has arrived?
- 'Whether' is more formal and preferred in writing; 'if' is more informal.
Common Mistakes
- Wrong: Could you tell me where is the station? Correct: Could you tell me where the station is? (normal order, not question order)
- Wrong: Do you know what does she want? Correct: Do you know what she wants? (no auxiliary do in embedded question)
- Wrong: I was wondering does he speak French. Correct: I was wondering if/whether he speaks French.

Frequently Asked Questions
What is an indirect question?
An indirect question is a question embedded inside a statement or polite request. Instead of asking directly (Where is the bank?), you embed the question: Could you tell me where the bank is? Indirect questions sound more polite and formal. The key grammar change is that the word order reverts to normal (subject before verb) and auxiliary verbs like 'do/does/did' are dropped.
What happens to word order in indirect questions?
In direct questions, the auxiliary verb comes before the subject: Where IS the bank? What DOES she want? In indirect questions, the word order becomes statement order — subject before verb: where the bank IS / what she WANTS. There is no inversion and no auxiliary 'do'. This is the most common mistake learners make with indirect questions.
When do I use 'if' or 'whether' in indirect questions?
Use 'if' or 'whether' when the original direct question is a yes/no question: Is she ready? → Do you know if/whether she is ready? Both are correct, but 'whether' is preferred in formal writing and when followed by 'or not': Could you tell me whether she is ready or not? 'If' is more informal. When a question word (who, what, where) is present, do not use 'if'/'whether'.
What are the most common introductory phrases for indirect questions?
Polite requests: Could you tell me...? Would you mind explaining...? Can you tell me...? Statement phrases: I was wondering... I'd like to know... I'm not sure... Do you happen to know...? Formal uses: I wonder... The question is... It is not clear... All are followed by a question word (or if/whether) + normal subject-verb order.
Do indirect questions end with a question mark?
It depends. If the introductory phrase is a direct question, end with a question mark: Could you tell me where the station is? If the introductory phrase is a statement, end with a full stop: I'd like to know where the station is. The test is whether the overall sentence asks the listener something or makes a declaration.
Do tenses change in indirect questions as in reported speech?
Yes, when the introductory phrase is in the past tense, the same backshift rules apply as in reported speech: 'Could you tell me...' (present) — no backshift needed. 'I wondered...' (past) — is becomes was, has becomes had, will becomes would: I wondered where she was. / She asked me if he had arrived.
What is the difference between an indirect question and a noun clause?
Indirect questions are a type of noun clause. The embedded question (where she lives / what he said) functions as a noun — as the object of a verb or complement of a preposition: I know where she lives (object). The answer depends on what he said (prepositional complement). All embedded questions are noun clauses, but not all noun clauses are questions (that-clauses are also noun clauses).
Can indirect questions be used in academic and professional writing?
Yes, indirect questions are common in formal writing to introduce uncertainty or pose research questions tentatively: This study seeks to understand why learners avoid certain structures. The question arises whether economic growth necessarily reduces inequality. The indirect question form (normal word order, no inversion) is always used in academic prose.
How are indirect questions used to be polite in professional situations?
In professional contexts (emails, interviews, customer service), indirect questions soften requests: Direct: Where is the toilet? Polite: Could you tell me where the toilet is? Direct: What is your budget? Polite: I was wondering what your budget might be. Indirect questions signal respect for the listener's time and knowledge.
Is indirect question formation tested in Cambridge and IELTS exams?
Yes. Correct embedded question word order is tested at B1 (PET), B2 (FCE) and C1 (CAE) levels. Common exam tasks include sentence transformation: 'Where does she live?' becomes 'Could you tell me where she lives?' In IELTS, indirect questions appear naturally in Academic Task 2 writing: It is not entirely clear whether this approach is effective.
