impolite to ask someone you don’t know very well?
Are there

any you wouldn’t ask a friend? Why?
Which might you need to ask someone but wouldn’t feel very comfortable about it?

example:
- Where's the department store? - Direct question
- Could you

tell me where the department store is, please? - Indirect question
- What's his name? - Direct question
- Do you know what his name is? - Indirect question

and a question which has no subject/verb inversion like a

normal question. For example:
- What's his name? >> - Do you know what his name is? - Indirect question
Here the polite expression is "Do you know...", and the question part is "...what his name is?". Note that the subject and verb have not changed place in the question part. So if you said "Do you know what is his name?", this would be incorrect.

idea what the time is? - Indirect question
The polite

expression is "Do you have any idea...?", and the question is "...what the time is?". The question is not "...what is the time?" - you don't invert the subject and verb kike a normal question.

questions when there is no other auxiliary verb. For example: -

You like Chinese food. >> - Do you like Chinese food?
Indirect questions do not use the auxiliary verb "to do" in the main question. For example: - When does the next train arrive? - Direct question - Do you know when the next train arrives? - Indirect question - Do you know when does the next train arrive? - Incorrect
Another example: - When does the restaurant close? - Direct question - Could you tell me when the restaurant closes? - Indirect question - Could you tell me when does the restaurant close? - Incorrect

a yes or no answer, we must use if or

whether between the polite question and the actual question part

Do you have a driving license? Yes, I do / No, I don’t.
 I’d like to know if / whether you have a driving license.

Have you been at your current company for a long time?
Would you mind telling me if / whether you’ve been at your current company for a long time?

all indirect questions are questions but they are polite statements

which encourage a response. Some common polite expressions include:
- I wonder (if/whether)...? - I can't remember (if/whether)...? - Could/Can you tell me (if/whether)...? - Would you mind telling me (if/whether)...?
-Have you any idea…? - Would it be possible for you to...? - Is there any chance you could...? - I don't suppose you could... - I'd like to know (if/whether)...
