A question word or interrogative pronoun is used in questions: how, what, who, where, why, when…? A question word appears at the beginning of a question or interrogative statement.
Questions in the present simple form of the verb “to be” and using a Question Word (or interrogative pronoun) follow the following formulae:
Positive form: Question Word + Am / Is / Are + Subject (+ Object) + ?
i.e. Who is a good vet? – Who are they?
Why is he a judge? – Why are they here?
When is it? – When are the classes?
Where is the flight attendant? – Where are the flight attendants?
What is this? – What are they?
How are you? – How are they?
Negative form: Question Word + Am / Is / Are + Subject + not (+ Object) + ?
i.e. Who isn’t well? – Who isn’t a good vet?
Why is he not a good judge? – Why isn’t he a good judge?
When is he not here? When isn’t he here?
Where are they not? – Where aren’t they?
What isn’t ok? – What is not ok?
How aren’t you ill? – How are you not ill?
Please be careful with the changes to the verb to be in the question form, especially with “I”: Why aren’t I?
