Hi,
Perhaps you could elaborate more specifically about indirect questions? What exactly does it mean?
The term 'reported questions' is also used.
Basically, the idea is that you hear someone ask a question and then you tell me (ie report to me) what the person said. You are not asking me a question, but simply telling me what the question was.
eg Tom: Does Mary speak Chinese?
John: Tom asked if Mary spoke Chinese.
Have you studied this kind of thing already?
Best wishes, Clive
