Questions about the predicate

To make a Wh- question about the predicate, simply add a wh- word (what, where, when, how, how much, etc) to the beginning of your yes / no question.

Note: the rest of your yes / no question disappears and becomes part of your answer. Look at the following examples:

Did you go out dinner?

When did you go out to dinner?

I went to dinner yesterday.

 

Were you at the mall on Saturday afternoon?

Where were you on Saturday afternoon ?
