Embedded Questions
Introduction
An embedded question is a question that is included inside another question or statement. They are common after introductory phrases, such as: I wonder Could you tell me Do you know Can you remember Let's ask We need to find out I'd like to know Could you tell me I'm not sure Would you mind explaining
Five Rules for Using Embedded Questions
Rule One
If the embedded question is part of a statement, use a period and not a question mark at the end of the sentence. Also, if the question is in the present or past simple verb tense, omit the auxiliary verbs do, does, and did and change the verb to its appropriate form, as in the example below.
Direct Question Embedded Question
What time did he leave? I wonder what time he left.
Rule Two
If the embedded question includes an auxiliary verb or the verb "to be", reverse the positions of the subject and the auxiliary verb, as in the examples below.

Can you help me? I wonder if you could help me.

1. Politely Asking for Information
Direct Question

Embedded Question
2. Talking About Something Which Is Unknown to the Speaker
