How, what, who, where, why, when

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.

  • Who? is used to ask a question about a person or people
  • Why? is used to ask a question about a reason
  • When? is used to ask a question about a moment in time
  • Where? is used to ask a question about a place
  • What? is used to ask a question about an object, an idea, an action
  • How? is used to ask a question about manner

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?
