Unlike direct questions, indirect questions are not normal questions. They have the same word order as statements and we do not use the verb 'do' to form a question.

Indirect questions examples
The indirect questions are more polite and more formal than the direct questions.

We can use many introductory phrases such as I ask, I wonder, I want/would like to know, I can't remember, I have no idea, I am sure etc., or they can be introduced by expressions such as Can you tell me, Do you know, Do you remember, Have you any idea.
