A question is a type of sentence that needs an answer.
Many of the words we use to open questions begin with the letters 'wh'. ('How' is the odd one out but it is still a question word.)
what / where / when / who / why / how
These words help us to turn statements into questions.
This is a statement:
His name is Peter.
It is the answer to this question:
What is his name?
