“Where is the library?” is clear. “Could you tell me where is the library?” sounds almost right, yet its word order is wrong for a normal indirect question. Change it to “Could you tell me where the library is?” and the question becomes natural. One small rearrangement has made the larger sentence work.
Direct questions ask for information in a main clause, often using inverted subject–auxiliary order: “Where is the library?” Indirect questions embed the question content in a larger expression, usually with ordinary subject–verb order: “Do you know where the library is?” Their core aim is to preserve what the speaker wants to find out while adjusting the form to a request, a statement of uncertainty or a report.
This article explains direct and indirect questions examples, indirect question word order, if versus whether, and exercises with answers. It complements the focused Embedded Questions in English guide and the connected Reported Speech article, without treating every embedded question as a polite request.
What changes when a question moves inside another sentence?
“What time does the train leave?” becomes “Do you know what time the train leaves?” The direct question needs does before the subject. The embedded clause instead puts the subject first, and leaves carries the agreement. A student who keeps does inside the new clause has usually followed a word-by-word transformation rather than reconstructing the grammar.
- “Where are they?” → “I wonder where they are.”
- “When does it start?” → “Could you tell me when it starts?”
- “Why did she leave?” → “I don’t know why she left.”
- “How much will it cost?” → “Do you know how much it will cost?”
Sometimes the direct question already has normal subject–verb order. “Who called you?” uses who as the subject. The embedded form is simply “I wonder who called you.” Contrast “Who did you call?” with “I wonder who you called.” Check whether the question word is the subject or object rather than reversing words mechanically.
Yes/no questions: when if and whether matter
“Is the hall open?” becomes “Do you know if the hall is open?” or “Do you know whether the hall is open?” A wh-word is unavailable, so if or whether introduces the embedded yes/no question. Whether is also the standard choice before a to-infinitive: “I am not sure whether to wait”, not “if to wait”. Both can be natural in many finite yes/no clauses.
The outer sentence decides the punctuation
“Could you tell me where the hall is?” is a question. “I wonder where the hall is.” is a statement. “The visitor asked where the hall was.” is also a statement, despite reporting an earlier question. Do not retain a question mark just because the clause begins with where. Read the whole sentence.
Indirect does not always mean polite
“Could you tell me where the exit is?” often sounds courteous, but “Where is the exit?” may be more effective in a genuine emergency. An embedded question can be a polite enquiry, a statement of uncertainty or part of reported speech. Students should choose the form that fits the situation rather than automatically making every question longer.
Four steps to repair an indirect question
- Find the outer sentence: am I asking, wondering or reporting?
- Identify a wh-question or an embedded yes/no question.
- Build the embedded clause with normal subject–verb order; use if/whether where needed.
- Check tense, reference and punctuation, then ask whether the original information request survived.
Direct and indirect questions: practice with answers
- 1. “Where is the station?” → “Could you tell me where ___?”
- 2. “When does the workshop begin?” → “Do you know when ___?”
- 3. “Why did they leave?” → “I wonder why ___.”
- 4. “Is the room available?” → “Can you find out ___ the room is available?”
- 5. “Who sent the invitation?” → “I don’t know who ___.”
- 6. Choose: “Please tell me when (the bus arrives / does the bus arrive).”
- 7. Choose: “I don’t know (whether to go / if to go).”
- 8. “I wonder how it works” ends with a full stop or a question mark?
- 9. “Could you explain how it works” ends with a full stop or question mark?
- 10. Repair: “Do you know where did she go?”
Answers: (1) the station is; (2) the workshop begins; (3) they left; (4) if or whether; (5) sent the invitation; (6) the bus arrives; (7) whether to go; (8) full stop; (9) question mark; (10) “Do you know where she went?” The form changes but the information required does not.
What independent mastery looks like
Give a student a situation: asking a librarian about opening hours. They first ask directly. Next they ask courteously. Finally, they write a sentence telling a parent what they still do not know. A student who can handle all three has understood that an embedded question is part of a larger message. In a three-student tutorial, one learner asks, another answers and the third checks whether the meaning remained clear.
When a learner keeps writing “where did she go” inside an indirect clause, diagnose question structure. When the word order is correct but the time changes unexpectedly, inspect tense and reported-speech decisions. Correct the point where understanding breaks, not merely the last visible word.
Frequently asked questions
Do all indirect questions use if? No. A wh-word introduces many embedded information questions. If and whether commonly introduce embedded yes/no questions.
Are indirect and reported questions identical? Reported questions are one use of embedded questions, but “Could you tell me where…” and “I wonder why…” illustrate other uses.
Are indirect questions always longer? Often, but length is not the aim. Choose a form that respects the reader’s needs and preserves the information being sought.
The core aim
English question mastery means that a listener can identify what is being asked and respond appropriately. The core aim of direct and indirect questions is to keep that information need clear while choosing the right grammatical frame. When the structure becomes natural, a student can adapt tone without sacrificing precision.
