Indirect questions

Indirect question (also called embedded question) is a statement within another statement/ question (polite expression). Indirect questions are polite, longer forms of normal questions.

For examples,

  •  What is your name? → I can't remember what your name is.
  •  Can you speak English?  → Can you tell me if you can speak English?

Some common polite expressions are:
  •  I wonder……………...……
  •  Do you know………………?
  •  I can't remember ...…………
  •  Could you tell me ... ………?
  •  I'd like to know .....…………. 
  •  Would you mind telling me ... ………?
  •  I can't remember...…….…… 
  •  Would it be possible for you to.…..…?

Changing direct questions to indirect questions

There are two types of questions: Yes/no question and Wh questions. When we change them to indirect questions, there is a slightly difference in form.

WH QUESTIONS

Form:

• A polite expression + a statement

Procedures:

Step 1: Change the question to statement word order. See the example,

  •  "Where do you live?"
  → Where you do live

Step 2: Remove auxiliary verb if necessary.

  → Where you do live

Step 3: Embed it in a polite expression.

  → I can't remember where you live.

Step 4: Check whether you need to punctuate with question mark "?" or full-stop ".".

  → Can you tell me where you live? ["?" is used when polite expression is a question.]
  → I want to know where you live. ["." is used when polite expression is a statement.]

Here are more examples,

  •  What's his name? 
  →  Do you know what his name is?
  →  Do you know what is his name? 

  •  What's the time? 
  →  Do you have any idea what the time is?

YES/NO QUESTIONS

Form:

• A polite expression + if / whether + a statement

Procedures:

Step 1: Change the question to statement word order. See the example,

Step 3: Add IF or WHETHER in front of re-ordered question.

Step 4: Embed it in a polite expression.

  → I can't remember if/whether you like apple.

Step 5: Check whether you need to punctuate with question mark "?" or full-stop ".".

  → Can you tell me if/whether you like apple? ["?" is used when polite expression is a question.]
