Word order in indirect questions

An indirect question is when a question is ‘inside’ another question.

Take a simple scenario: we stop someone in the street and ask: “Where is the supermarket?” This is what we call a direct question.

However, let’s say that we begin with Can you tell me? or Do you know? Our original question is now ‘inside’ the new question: Can you tell me where the supermarket is?

You will see that the word order has now changed because technically the question is now Can you tell me? not Where is? This is what we call an indirect question.
