What Are WH Words?

WH words are words used to ask for specific information. Unlike simple Yes/No questions, WH questions cannot be answered by just “yes” or “no”. They start with a WH word followed by a verb and subject depending on the sentence type.

Who – asks about a person
What – asks about a thing or activity
When – asks about time
Where – asks about place
Why – asks for reasons
Which – asks about choice or preference
Whose – asks about possession
How – asks about manner, condition, or degree

This simple mental map helps visualize how each WH word connects to a type of information we want to find.

Basic Structure of WH Questions

Most WH questions follow a predictable structure:

WH word + Auxiliary Verb + Subject + Main Verb + (Rest of sentence)?

Example:

Where do you live? → WH (Where) + Auxiliary (do) + Subject (you) + Verb (live).
What does he do?
Why are they late?

When the WH Word Is the Subject

There’s no need for an auxiliary verb when the WH word acts as the subject.

Who broke the glass? (Here, “who” is the subject)
What happened?

Types of WH Question Forms

1. WH + Aux + Subject + Verb

This is the most common structure for questions using auxiliary verbs like do / does / did.

Example: What do you eat for lunch?

2. WH + Be + Subject

Used when “be” is the main verb.

Example: Where are the documents?

3. WH + Modal + Subject + Verb

Used when a modal verb like can, should, would, could, will appears.

Example: Why can you drive at night?

4. WH + Possessive Form (Whose)

Example: Whose pen is this?

How to Form Questions Interactively

You can create WH questions by identifying what information is missing in a statement. Let’s see how that works.

Statement: She lives in Delhi.
Missing Information: Place
Question: Where does she live?

Try it yourself:

He is eating an apple. → What … ?
They arrived at 7 PM. → When … ?
You borrowed someone’s book. → Whose … ?

Think carefully about the missing part — that determines which WH word you should use.

Common Mistakes with WH Questions

❌ Where you are going? → ✅ Where are you going?
❌ What he doing? → ✅ What is he doing?
❌ Why you like it? → ✅ Why do you like it?

The position of the auxiliary verb (do, does, is, are) always comes before the subject in English question forms.

WH Questions with “How” Forms

“How” is especially flexible and forms many useful question expressions:

Form	Meaning	Example
How much	Quantity (uncountable)	How much rice do you need?
How many	Quantity (countable)	How many students are there?
How often	Frequency	How often do you exercise?
How long	Duration	How long have you lived here?
How far	Distance	How far is the station?
How old	Age	How old are you?

Practice and Interactive Learning Idea

For self-practice, try converting ordinary sentences into WH questions by asking yourself what you want to know. For example:

Statement: “She bought a new car.” → Question: “What did she buy?”
Statement: “They travel on Sundays.” → Question: “When do they travel?”
Statement: “He lives with his parents.” → Question: “Who does he live with?”

This thought exercise trains your brain to identify the information gap, which is the essence of forming natural WH questions.

Conclusion

WH words form the backbone of meaningful communication in English. By understanding how to use who, what, when, where, why, and how, you not only improve your grammar but also your ability to express curiosity and interact naturally. Keep practicing, observe patterns in conversations, and soon forming WH questions will become effortless.
