If your students have ever written "Can you tell me where is the station?" and lost points on a grammar question, they've fallen into one of the most common—and most avoidable—traps in English grammar. Indirect questions look simple, but they follow a rule that directly contradicts how students naturally think about questions.
What Is an Indirect Question?
A direct question asks something outright: Where is the station? An indirect question embeds that same question inside a larger sentence, usually to sound more polite or formal.
- Direct: Where is the station?
- Indirect: Can you tell me where the station is?
Both sentences ask the same thing, but the word order is completely different.
The #1 Rule: Flip the Word Order
In a direct question, the verb comes before the subject (is the station). In an indirect question, the word order changes to match a statement: subject first, then verb (the station is). This is the rule students most often miss because their instinct is to keep question word order throughout the whole sentence.
| Direct Question | Indirect Question |
|---|---|
| Where is the library? | Do you know where the library is? |
| What time is it? | Can you tell me what time it is? |
| Why were you late? | I'd like to know why you were late. |
Drop the Auxiliary "Do"
When turning a direct question into an indirect one, students must also drop the auxiliary verbs do, does, and did, then conjugate the main verb correctly.
- Direct: When does the lesson end?
- Indirect: Could you tell me when the lesson ends? ✅
- Wrong: Could you tell me when does the lesson end? ❌
Yes/No Questions Need "If" or "Whether"
When the original direct question has no question word such as who, what, or where, the indirect version must introduce the embedded question with if or whether.
- Direct: Is this the right answer?
- Indirect: Do you know if this is the right answer?
- Indirect: Do you know whether this is the right answer?
Whether is usually the safer, more formal choice, especially in academic writing and on standardized tests.
No Question Mark—Unless the Whole Sentence Is a Question
If the main sentence is a statement, there is no question mark at the end, even though a question is embedded inside it.
- She needs to know where you are going. ✅
- Does she need to know where you are going? ✅

Quick Reference Checklist
Before submitting any answer involving an indirect question, check these rules:
- ☑ The subject comes before the verb
- ☑ Do not keep do, does, or did as helper verbs
- ☑ Yes/no questions use if or whether
- ☑ Use no question mark if the main clause is a statement
Try this: Which is correct—"I wonder where does he live" or "I wonder where he lives"?
If this explanation helped, share it with a student preparing for the DSAT, EST, or ACT. One grammar rule mastered today can mean one more point on test day.
