Although this is basic grammar, many learners find a lot of trouble in asking questions correctly. So let's review their structure.
(Wh question) + Auxiliary verb + Subject + Verb = (WH) + A + S + VTo ask questions in English, we have to bring the auxiliary verb before the subject:
You are talking . Are you talking ? ( ASV : auxiliary + subject + verb)
He has arrived . Has he arrived? ( ASV )
It'll be there . Will it be there ? ( ASV )
Present and past simple don't use auxiliary verbs in affirmative sentences, but use do and don't in negative sentences and questions.
I work hard. Do you work hard? (ASV)
She called. Did she call? (ASV)
If we add a WH -question before, the ASV order will remain the same.
We are eating burgers. What are you eating? (Wh + ASV)
We went there. Where did you go? (Wh + ASV)
I told Sally. Who did you tell? (Wh + ASV)
