• Embedded Information Questions

• 
• Embedded information questions use a question word. Do not use question word order in embedded questions. Use normal word order (wh-word + subject + verb).

  
  

  Regular question: Where can I recycle glass bottles?

  Embedded question: Do you know where I can recycle glass bottles? 

  
  

  If an information question contains a wh-word and do, remove do from the embedded question. 

  -Regular question: Where does she live?
  

  -Embedded question: Can you tell me where she lives?

• How can we reduce plastic waste?	Do you know how we can reduce plastic waste?
  Why is the greenhouse effect a threat to the environment?	Do you understand why the greenhouse effect is a threat to the environment?

• Remember! An embedded information question is a type of noun clause. (relative pronoun + subject + verb)
