What is the WH type structure?

A wh-word or phrase appears at the beginning of the question to the left of the subject, followed by a "helping verb." The helping verb will be some form of "auxiliary verb" (AUX) such as do (does, did, etc.), be (is, are, was, etc.), or have (has, had, etc.).

Introduction

Wh-questions are questions that start with a wh-word such as what, where, when, how, and why. The answer to these questions cannot be yes or no. In this article, we will define wh-questions and explore their structure and use. Illustrative examples will be provided.

Let’s get started with the types of questions in English!

Types Of Questions In English

Questions can be broadly categorized into three types:

Wh-Questions In English: Definition, Question Words, Structure, And Examples (1)

Wh-questions in English are interrogative sentences that begin with words like “who,” “what,” “where,” “when,” “why,” or “how.”

These questions seek specific information and are used to ask about various aspects, including people, things, places, times, reasons, and methods. Wh-questions invite detailed responses. An answer with yes or no is not acceptable for these questions.

Example:

Question words

Question words, commonly referred to as “wh-questions,” derive their name from the inclusion of the letters “W” and “H.”

Wh-Question Structures

Asking wh-questions may sometimes require changes in sentence structure.

Asking About The Subject

If you ask about the subject of the sentence, simply add the question word at the beginning:

Example: James writes good poems. — Who writes good poems?

As you can see, apart from replacing “James” with “who“, there isn’t much change!

Asking About The Predicate

If you ask about the predicate of the sentence (the part containing the verb and providing information about the subject), there are three options:

If a helping (auxiliary) verb precedes the main verb (e.g., can, is, are, was, were, will, would…), add the question word and invert the subject and the helping (auxiliary) verb.
- Examples:
  - He can speak Chinese. — What can he speak?
  - They are leaving tonight. — When are they leaving?
If you ask about the predicate, and there is no helping (auxiliary) verb, and the verb is “to be,” simply add the question word and invert the subject and the verb.
- Example:
  - The play was interesting. — How was the play?
If there is no helping (auxiliary) verb in the predicate, and the main verb is not “to be,” add the auxiliary “do” in the appropriate form.
- Examples:
  - They go to the movies every Saturday. — Where do they go every Saturday?
  - He wakes up early. — When does he wake up?
  - They sent a letter. — What did they send?

How to Form Negative Wh-Questions?

When forming negative wh-questions, we use the auxiliary verb “do” when there is no other auxiliary or modal verb:

Affirmative Wh-Questions	Negative Wh-Questions
Where did you go?	Where didn’t you go?
Who can bring a laptop?	Who can’t bring a laptop?
Who is happy?	Who is not happy?
Who wants an ice cream?	Who doesn’t want an ice cream?
Which door opened?	Which door didn’t open?
Which worked for you?	Which didn’t work for you?
Where did you go?	Where didn’t you go?

Conclusion

In summary, wh-questions, characterized by the use of wh-words, serve as powerful tools for extracting detailed information. Unlike yes or no questions, they require comprehensive responses. It’s crucial to note that when these questions extend beyond the subject of the sentence, the inclusion of auxiliaries becomes essential. To master the art of forming and using wh-questions effectively, consistent practice is key. This may enable a deeper understanding of their structure and use.
