Question Words in English (With Exercises and Free Resources)

How many questions do you ask in a day? One study says that a child asks 73 questions a day on average. Most of these questions will rely on a question word. For this reason, question words in English are super important for our everyday speech. So the question is, are you using them right?

In this article, we will go over the most important question words and how they are used. We will follow this up with some exercises to test how much you understand these question words (or interrogative words). By the end of this post, you’ll be a question master (or at least be on your way). Let’s get started.

The 9 Main Questions Words in English

What/Which: What is used when asking for information or confirmation.
Which is used when asking about a choice.

What kinds of meat do you like?
Which meat do you want? Chicken or beef?

Who

Who is used to ask questions about people.

Who is she?
Who do you work for?
Who helped you with that?

Whom

Whom is also used for questions about people. Technically, whom replaces who when the question word is being used as an object of a verb or preposition. However, we rarely use whom beyond very formal writing.


With whom did you play that game?

Whose

Whose is used to ask questions of ownership. In other words, determining who an object/thing belongs to.

Whose pen is this?
Whose car did you borrow?

When

When is used to ask questions about time. Though, if we just want to know the time right now, we use what (What time is it?). Most other time questions use when.

When will you pick up your friend from the airport?
When did you graduate from high school?

Why

Why is used to ask for an explanation or a reason.

Why is he so angry? (Explanation)
Why didn’t you go to prom? (Reason)

Why Don’t

When combined with don’t, why becomes a suggestion in the form of a question.

Why don’t you visit him? (Suggestion)
Why don’t you try it? (Suggestion)

Where

Where is used to ask questions about a place or location.

Where will we meet up tonight?
Where did you say your school was?

How

How has several uses in English. The main one is to ask for instructions. However, we also use how to inquire about the quality of something or the extent of something. When asking about the extent of something, we pair it with an adjective (i.e. how fast) or adverb (i.e. how quickly).

How do you write a letter? (Instruction)
How is the fish today? (Quality)
How long can you hold your breath? (Extent)

What

What is used to ask for information.

What do you like?
What kind of car do you own?

Which

Which is often confused with what as, in some cases, they overlap. Which is used to ask someone about a choice between a limited number of options.

Which kind of bread do you want?
Which chair would you prefer?

In both of the above sentences, we could use what instead of which. Generally, when there are a small number of choices, we will use which. But, if there are many potential options, we will use what.
