Form : ( Indirect question phrase + question word / if / whether + subject + verb )

In English, in more formal situations, we often use indirect questions because they sound more polite.

To make a question more polite we often begin with an indirect question phrase such as:

• Could you tell me...?
• Do you know...?
• Have you any idea...?
• Can you tell me...?

Example questions :

DIRECT QUESTION : Where is the post office?

INDIRECT QUESTION : Do you know where the post office is?

DIRECT QUESTION : What's the time?

INDIRECT QUESTION : Could you tell me what the time is?

DIRECT QUESTION : Does this train go to Brighton?

INDIRECT QUESTION : Can you tell me if this train goes to Brighton?

DIRECT QUESTION : Is there a bank nearby?

INDIRECT QUESTION : Have you any idea whether there is a bank nearby?

Note for use of indirect questions :

If the direct question begins with an auxiliary verb ( no question word), add 'if' or 'whether' after an indirect question phrase to make the question indirect.

We don't use 'if' or whether with Do you think...?

eg. Do you think he's gone to London? NOT Do you think if he's gone to London?
