What Are Interrogative Pronouns?

Imagine a world without questions—no curiosity, no learning, and definitely no quizzes! Interrogative pronouns are our trusty allies in forming questions. They help us gather information, clarify doubts, and spark engaging conversations. In a nutshell, these pronouns are like keys that unlock the door to information.

Interrogative Pronouns Definition

Interrogative pronouns are a type of pronoun that is used to introduce questions and inquiries in sentences. They replace nouns and are specifically designed to seek information about people, things, actions, qualities, or ideas. Interrogative pronouns guide conversations by initiating queries and directing attention toward the subject of the question. Interrogative pronouns include words like “who,” “what,” “which,” and “whom.”

List of Interrogative Pronouns and Explanation

Interrogative pronouns are your English language companions when you want to know more, dig deeper, and unravel the mysteries around you. Let’s see the list of common interrogative pronouns that make questions come to life:

1. Who: This interrogative pronoun is your go-to for discovering people and their identities. Use it to ask about individuals or groups.

  • Example: “Who is the new student in class?”
  • Example: “Who are your favorite authors?”

2. What: Curious about things, actions, or ideas? “What” is your ticket to uncovering information about objects, events, and concepts.

  • Example: “What is your favorite movie?”
  • Example: “What did you do over the weekend?”

3. Which: When options abound, “which” steps in. It helps you choose among alternatives and clarify preferences.

  • Example: “Which flavor of ice cream do you want?”
  • Example: “Which route should we take to the park?”

4. Whose: Dive into the realm of possession with “whose.” It helps you figure out the owner or source of something.

  • Example: “Whose notebook is this?”
  • Example: “Whose idea was it to plan a picnic in summer?”

5. Whom: Need to focus on the object of an action? “Whom” directs your inquiry toward the receiver of an action.

  • Example: “To whom did you lend your umbrella?”
  • Example: “Whom did she invite to the event?”

6. Why: Unravel the motivations, reasons, and explanations behind actions with “why.”

  • Example: “Why did you choose to study abroad?”
  • Example: “Why did they cancel the meeting?”

7. How: Unlock the methods, manners, and processes behind actions or situations with “how.”

  • Example: “How do you bake a perfect cake?”
  • Example: “How did she learn to play the violin?”

Interrogative vs. Relative Pronouns

Pronouns serve as connectors in sentences, and interrogative and relative pronouns are two important types. Though they serve distinct purposes, their similarities might lead to confusion. Let’s unravel the differences between interrogative and relative pronouns to enhance your understanding of these two types of pronouns.

Interrogative PronounsRelative Pronouns
PurposeInitiate questions to seek information.Connect ideas by introducing dependent clauses.
ExamplesWho, What, Which, Whose, WhomWho, What, Which, Where, Whose, Whom
FunctionLead inquiries into unknown details.Bridge independent and dependent clauses with context.
Example SentencesWho won the game?
What is the solution?
The person who won is my friend.
This is the place where I met your mother.

Interrogative pronouns directly introduce questions, seeking answers to uncover details about people, things, actions, or ideas.


  • “Who attended the party?”
  • “What is the core topic of the presentation?”
  • “Which book did your mother borrow from the library?”

In each instance, interrogative pronouns lead the way, initiating inquiries into the unknown.

Now, imagine you’re crafting a sentence that connects two ideas. Relative pronouns step in as the bridge between these concepts. They link a dependent clause (providing additional information) to an independent clause (expressing a complete thought).


  • “The person who won the race is my friend.”
  • “I read the book that you recommended.”
  • “This is the place where Mr. Smith lost his wallet.”

In these examples, relative pronouns (like “who,” “that,” and “where”) not only connect but also introduce crucial information to provide context.

Who vs. Whom

The “who” and “whom” duo often prompt questions of their own: When do you use “who,” and when should you opt for “whom”? Let’s unravel this grammatical puzzle and demystify the usage of these two pronouns.

Understanding “Who”:

“Who” is the subject pronoun, use it when you’re talking about the subject of a sentence. It’s like shining a spotlight on someone who’s actively doing something. If the person you’re referring to is performing the action, you’d typically use “who.”


  • “Who is joining us for dinner?”
  • In this case, “who” identifies the person (subject) who will be participating in the action (joining for dinner).

Understanding “Whom”:

“Whom” is the object pronoun, and takes on the role of the object—a recipient of the action. It often appears after prepositions like “to,” “for,” “with,” or “by.” If the person is on the receiving end of an action, you’ll usually find “whom.”


  • “To whom should I address the letter?”
  • Here, “whom” is used because the person is the recipient of the action (addressing the letter).

Quick Tips for Choosing:

  • Subject Role: If the person is doing the action, use “who.”
  • Object Role: If the person is receiving the action, particularly after a preposition, opt for “whom.”

What vs. Which

Navigating between “what” and “which” might seem like choosing between similar options, but each has its own distinct role in crafting questions. Let’s unravel the nuances of “what” and “which” to help you use them effectively.

Understanding “What”:

“When” you want to inquire about a general thing, action, or idea, “what” is your trusty companion. It opens the door to exploration, allowing you to gather information without specifying particular options.


  • “What is your favorite hobby?”
  • Here, “what” seeks a broad category—your preferred leisure activity.

Understanding “Which”:

“Which” comes into play when choices abound. It’s your tool for selecting from a set of options, making your question more specific by indicating a range to choose from.


  • “Which movie are we watching tonight?”
  • In this instance, “which” highlights that there’s a selection of movies available, and you’re asking for a decision among them.

Quick Tips for Choosing:

  • General Inquiry: If you’re seeking general information, opt for “what.”
  • Choice Inquiry: If you’re offering options or looking for a selection, go with “which.”

Interrogative Pronouns vs. Interrogative Adjectives

Navigating the world of grammar can be a bit like exploring a new landscape. When it comes to interrogative pronouns and interrogative adjectives, the ground might seem similar, but they each have their own distinct roles. Let’s break down the difference:

Key Difference:

Interrogative pronouns stand alone and replace nouns, while interrogative adjectives modify nouns and work alongside them in questions.

Interrogative Pronouns: Think of interrogative pronouns as the question makers themselves. They stand alone in sentences and directly ask about something. They replace nouns in questions to uncover information.


  • Original Sentence: “Who is coming to the party tonight?”
  • Here, “who” is the interrogative pronoun because it’s asking about a person, replacing the need for a noun.

Interrogative Adjectives: Now, picture interrogative adjectives as the question-asking sidekicks. They modify nouns and show up in questions that inquire about specific qualities or details of the noun.


  • Original Sentence: “Which book are you reading?”
  • In this case, “which” is the interrogative adjective because it’s modifying the noun “book” and asking about a specific quality.

Using Both:

It’s important to note that sometimes, both interrogative pronouns and interrogative adjectives can appear in the same question, depending on the depth of the inquiry.


  • Original Sentence: “Which book are you reading, and what is it about?”
  • Here, “which” (interrogative adjective) modifies “book,” and “what” (interrogative pronoun) directly asks about the subject of the book.

So, when crafting questions, remember that interrogative pronouns are your go-to for direct inquiries, while interrogative adjectives add specific details to your questions about nouns. Together, they create a harmonious duo that fuels your language curiosity.

Interrogative Pronouns in Different Voices

Interrogative pronouns can effortlessly adapt to different voices in a sentence. The voice of a sentence—whether active or passive—can significantly impact how information is presented. Let’s explore how interrogative pronouns seamlessly integrate into different voices, adding shades to your questions:

1. Active Voice:

When we use active voice, the subject of the sentence performs the action. Interrogative pronouns in the active voice highlight the doer of the action, creating questions that engage with a sense of agency.


  • “Who made this delicious cake?”
  • “What inspired you to start painting?”
  • “Why did she choose that particular dress?”

These questions shine a spotlight on the individuals responsible for the actions, inviting discussions about their intentions and contributions.

2. Passive Voice:

On the other hand, in the passive voice, the subject of the sentence receives the action. Interrogative pronouns in the passive voice focus on the recipient of the action, allowing you to delve into processes and outcomes.


  • “By whom was this beautiful painting created?”
  • “For what purpose was this research conducted?”
  • “How was this impressive structure designed?”

These questions lead conversations into the realm of processes, impacts, and the results of actions taken.

3. A Harmonious Blend:

Interrogative pronouns seamlessly adapt to both voices, allowing you to craft questions that suit the tone and emphasis of your communication. Whether you want to highlight the doer or receiver of an action, these pronouns play a pivotal role in creating well-rounded questions.


  • “Who invited you to the event?” (Active Voice)
  • “By whom were these breathtaking photos captured?” (Passive Voice)
  • “What motivated you to write this heartfelt letter?” (Active Voice)
  • “For what reason was this decision all the way supported?” (Passive Voice)

4. Whose: “Whose” leads you to ownership and possession. It reveals the individual associated with something.
