What is an indirect question, and why does the word order change?
An indirect or embedded question sits inside another sentence after an introductory phrase such as Could you tell me…, Do you know…, I wonder… or I have no idea…. It concerns the same specific information as the direct question, but has a different grammatical form.
In most direct questions, an auxiliary or modal verb precedes the subject: Where does she work? An embedded question requires statement order: Could you tell me where she works? A question about the subject itself, such as Who works here?, already has this order.
This rule focuses on questions with a question word: wh-questions. Choosing if/whether for yes/no questions and choosing the introductory phrase are neighbouring topics. Here, the introduction is provided, and the task is to change what follows the question word.
Direct: When does the pharmacy open? Embedded: Do you know when the pharmacy opens?
Direct: When does the pharmacy open? Embedded: Do you know when the pharmacy opens?
After when, the subject the pharmacy precedes opens. Remove does and add -s to opens.
Direct: What time did the workshop finish? Embedded: I have no idea what time the workshop finished.
Direct: What time did the workshop finish? Embedded: I have no idea what time the workshop finished.
The same change applies in the past: did disappears, and finished carries the past tense.
The main rule: subject before verb
An embedded question has the same word order as an ordinary statement: the subject precedes the verb. This applies whether the construction contains a lexical verb, be or a modal verb.
Compare Where is the manager?, where is precedes the manager: this is inversion. In Do you know where the manager is?, the manager comes first and is follows, just as in the statement The manager is in the office.
Keeping inversion inside the embedded question, as in Do you know where is the manager?, is a common difficulty. Learners often remember the direct question as a complete ready-made pattern.
introductory phrase + question word + subject + verb (+ other sentence elements)
- subject / S —
- The grammatical subject: who or what the clause is about; the verb agrees with it. In The book was written, the book is the subject, although someone else does the action.
- verb / V —
- A word for an action or state, such as work or be. The pattern determines its form.
Do you know where the nearest cash machine is?
Do you know where the nearest cash machine is?
The nearest cash machine is the subject and is is the verb. They follow statement word order.
I'm not sure how far the campsite is from the road.
I'm not sure how far the campsite is from the road.
The same principle applies with how far: the subject the campsite precedes is.
What happens to do/does/did?
In a neutral affirmative direct question, do/does/did helps form the question. An embedded question no longer needs that auxiliary: the main verb expresses tense and person. Emphatic do can remain for emphasis, however: I wonder what she does want stresses what she actually wants.
The main verb therefore changes form. In the present tense with a third-person singular subject, it takes -s: the shop closes, not the shop close. In the past tense, it takes its Past Simple form, V2: the train arrived, not the train arrive.
If the direct question uses be or a modal such as can, must or should, there is no do/does/did to remove. Reposition the subject, leaving be or the modal unchanged.
does/did + base verb (direct) → main verb with the correct tense/person (indirect)
- verb / V —
- A word for an action or state, such as work or be. The pattern determines its form.
- V1 / base form —
- The base verb without to: work, go, be.
Direct: Why does the printer jam so often? Embedded: I wonder why the printer jams so often.
Direct: Why does the printer jam so often? Embedded: I wonder why the printer jams so often.
Does disappears and -s appears on jams because the printer is third-person singular.
Direct: Who did the committee choose for the role? Embedded: Nobody has told me who the committee chose for the role.
Direct: Who did the committee choose for the role? Embedded: Nobody has told me who the committee chose for the role.
Did disappears, and the irregular form chose expresses the past tense.
Negatives: doesn't, didn't and isn't stay
A negative auxiliary is not the same as ordinary affirmative do/does/did. In a negative direct question such as Why doesn't he answer?, the auxiliary carries not. Removing it would lose the negative meaning.
Keep the negative auxiliary in the indirect question and remove only the inversion: the subject precedes it rather than follows it. Why doesn't he answer? → I wonder why he doesn't answer.
A common overgeneralisation is to remove doesn't or didn't after learning that do/does/did disappears. This can produce the ungrammatical I wonder why he answer: the negative meaning is lost completely, and the verb also lacks agreement.
negative direct question: doesn't/didn't/isn't + subject → indirect: subject + doesn't/didn't/isn't (auxiliary unchanged)
- subject / S —
- The grammatical subject: who or what the clause is about; the verb agrees with it. In The book was written, the book is the subject, although someone else does the action.
- auxiliary —
- A helping verb used to form tenses, questions or negatives: do, have, be.
Direct: Why doesn't the lift work on this floor? Embedded: Could you explain why the lift doesn't work on this floor?
Direct: Why doesn't the lift work on this floor? Embedded: Could you explain why the lift doesn't work on this floor?
Doesn't remains intact. Only the positions of the lift and doesn't change.
Direct: Why hasn't the invoice arrived yet? Embedded: I don't understand why the invoice hasn't arrived yet.
Direct: Why hasn't the invoice arrived yet? Embedded: I don't understand why the invoice hasn't arrived yet.
The same applies to hasn't: keep the negative meaning and change only the order.
Question mark or full stop? The introduction decides
A question word inside a sentence does NOT determine its final punctuation. The final mark depends on the complete introductory construction: is it a question to the listener, or a statement about what someone knows or does not know?
Could you tell me…?, Do you know…? and Would you mind telling me…? are themselves grammatical questions. The complete sentence therefore ends in a question mark, although the embedded part does not use question word order.
I don't know…, I'm not sure…, I have no idea… and Nobody has told me… are statements. They therefore end in a full stop even when they contain a question word.
Do you know why the workshop was cancelled?
Do you know why the workshop was cancelled?
Do you know is a question addressed to the listener, so the sentence ends with ?.
I have no idea why the workshop was cancelled.
I have no idea why the workshop was cancelled.
I have no idea is a statement, so use a full stop even though it concerns the same information.
The question phrase follows the complete introduction
The question word or phrase remains in the embedded question because it identifies the information being sought. This includes where, when, why, how, what, who, whose and which, as well as how much, how many, how long and how far.
The boundary falls between the whole introductory phrase and the embedded question: Could you tell me | where the harbour is? Tell is followed by me, so the question word does not always immediately follow the introductory verb. Preserve the necessary grammatical roles within the embedded part.
If the question phrase itself is the subject, as in Who left the message? or Which door leads outside?, the direct question already has no inversion. The embedded part therefore looks almost the same; the final punctuation may change according to the introduction.
Could you tell me whose bag this is?
Could you tell me whose bag this is?
Whose bag is a complete question phrase. Keep it together rather than separating whose from bag.
Do you know which door leads to the car park?
Do you know which door leads to the car park?
Which door is the question's subject, so the following word order is the same as in the direct question.
Keep the tense: this is not a reported question
This lesson concerns information being sought now in an embedded form, often politely, rather than reporting someone else's earlier question. Keep the tense used in the direct question: present stays present, and past stays past.
In reported speech after past-tense asked, tense often shifts back: She asked me what time the train left. Backshift depends on context and is not automatic in every report. The current questions practised here do not require it.
Pronouns likewise do not change merely because the question is embedded. When addressing someone in the current conversation, retain the subjects and personal pronouns that naturally express the speaker's intended meaning.
Do you know why the meeting was moved to Friday?
Do you know why the meeting was moved to Friday?
Was moved remains past tense. This is the speaker's current question about a past event, not a report of someone else's words.
Could you tell me why the shop closes early on Mondays?
Could you tell me why the shop closes early on Mondays?
Closes remains present tense because the question concerns a current regular fact.
Common sources of error and how to avoid them
The most common mistake is copying a whole direct-question pattern, such as where is, does he live or did they arrive, into an indirect question without removing inversion and unnecessary do. Rebuild the part after the question word mentally as a statement each time.
A second mistake is removing too much: deleting even an auxiliary that carries negation, such as doesn't, didn't or hasn't. Check whether it is needed to express not. If so, keep it. Remove ordinary affirmative do only when its sole purpose was to form the direct question.
A third mistake is choosing punctuation because a question word is present. Check the introduction instead: mentally set aside the embedded question and decide whether the introduction is itself a question, Do you know…?, or a statement, I'm not sure….
I wonder how often the ferries run in winter.
I wonder how often the ferries run in winter.
I wonder is a statement about the speaker's curiosity, so it ends in a full stop rather than a question mark.
Could you remind me what time the appointment starts?
Could you remind me what time the appointment starts?
Could you remind me is a grammatical question, so the sentence ends with ?. Within the embedded question, starts follows its subject, the appointment, in statement order.
Common mistakes
Incorrect:Do you know where is the nearest post office?
Correct:Do you know where the nearest post office is?
The incorrect embedded question retains question order, with is before the subject, instead of using statement order.
Incorrect:I'm still not sure what time does the lecture begin.
Correct:I'm still not sure what time the lecture begins.
Does has been carried over unnecessarily from the direct question. The form begins should express tense and person.
Incorrect:I wonder why he doesn't answers emails.
Correct:I wonder why he doesn't answer emails.
Keep the negative doesn't and use the base form answer after it. If the original sentence is affirmative, do not add a negative without a reason.
Incorrect:I have no idea what time the shop closes?
Correct:I have no idea what time the shop closes.
I have no idea is a statement, not a question. End the sentence with a full stop despite the question phrase inside it.
Incorrect:Could you tell me when the museum open?
Correct:Could you tell me when the museum opens?
The embedded question does not need does, but its present-tense verb must agree with museum: opens.
Incorrect:Do you know where he live now?
Correct:Do you know where he lives now?
After removing does, the main verb must agree with its third-person singular subject: lives, not live.
