More properly, question words can be called ‘interrogative’ words.
<u>Who – What – Where – Why – Which – When – Whose – Whom – How</u>
‘Can’, ‘should’ and ‘would’ are other words used to ask questions in English. These words tend to require a ‘yes’ or ‘no’ answer, or an affirmative. Since these question word lead to an expected answer, they are not really questions.
