Where is it?
Can you tell me where it is?
Take a look at the table below:
Direct questions can be simple questions:
Are you at home?
Who won the match?
What did they win?
If there is a ‘helping verb’ (auxiliary verb), for example will, was, have and can, we put the subject after the auxiliary verb:
Can you help me?
Where will Allie be tonight?
How many languages can you speak?
In present simple and past simple questions, we use do/does/did:
Where do they live?
Did you call me?
Indirect questions have the same word order as statements (subject before verb):
Do you know how long the journey takes?
We do not use do/does/did in the question:
⛔Do you know how long does the journey take?
If there is no question word (who, where, why, how, etc.) in the direct question, we can use if or whether
in the indirect question:
I wonder if she replied to your email.
I wonder whether she replied to your email.
