Embedded Questions — Rules, Examples & Exercises

An embedded (indirect) question is a question included inside another sentence or clause. It uses statement word order (subject + verb) rather than the inverted order of a direct question. Example: Where does she work? (direct) → Do you know where she works? (embedded).

Embedded questions use statement word order: subject + verb. Do not invert the subject and auxiliary, and do not use the auxiliary 'do/does/did'. Wrong: Do you know where does she live? Correct: Do you know where she lives? The question word (where, what, when) becomes a conjunction linking the clause.

Use 'if' or 'whether' when the direct question is a yes/no question (no question word). They replace the inverted structure: Is she coming? → I wonder if/whether she is coming. 'Whether' is more formal and is the only option before 'or not' and before infinitives: I don't know whether to go.

It depends on the introductory clause. If the whole sentence is a question, use a question mark: Do you know where she works? If the whole sentence is a statement, use a full stop: I don't know where she works. The embedded clause itself does not change the punctuation; the main clause determines it.

'Whether' is more formal than 'if' and is preferred in academic writing. Only 'whether' can be used before 'or not': I'm unsure whether or not she will agree (not 'if or not'). Only 'whether' can introduce an infinitive: She hasn't decided whether to go. 'If' is more common in informal speech.

Yes. Embedded questions most often appear inside statements: I don't know who she is. I wonder what time it starts. I'm not sure whether he's coming. They also appear inside questions: Could you tell me where the office is? The introductory clause can be a statement or a question; the embedded clause always uses statement word order.

In direct questions, word order inverts to signal the question type. In embedded questions, the question word already signals the information sought, so inversion is unnecessary and grammatically incorrect. The embedded clause functions as a noun clause (a kind of noun phrase) rather than an independent question, so it follows statement syntax.

Common phrases: Could you tell me...? Do you know...? I'd like to know... I wonder... I'm not sure... Can you explain...? I have no idea... Would you mind telling me...? These phrases are polite and formal, making embedded questions useful in professional communication and exam writing tasks.

Yes. In academic writing, embedded questions are common for expressing uncertainty or posing research questions: It remains unclear whether the data supports this conclusion. The study examined how participants responded. They allow you to introduce questions indirectly without disrupting the formal, objective tone of academic prose.

Yes. Embedded question word order is frequently tested in Cambridge Use of English (error correction, key word transformation) and IELTS Writing and Speaking. Errors such as 'Do you know where does she live?' are common mistakes that examiners flag. Practising the transformation from direct to indirect question form is very worthwhile.
