Interrogative pronouns are words used to ask questions in a sentence. They are a specific type of pronoun that helps to gather information about people, things, or ideas. In English, the main interrogative pronouns are “who,” “whom,” “whose,” “what,” and “which.”

These pronouns serve several important functions in language:

1. Asking about identity: “Who is that person?”
2. Inquiring about possession: “Whose book is this?”
3. Seeking information about objects or concepts: “What is the capital of France?”
4. Requesting a choice from options: “Which color do you prefer?”

Interrogative pronouns can be used in various sentence structures and can function as different parts of speech depending on their context. For example:

• Subject: “Who called you yesterday?”
• Object: “Whom did you invite to the party?”
• Possessive: “Whose car is parked outside?”

Understanding and correctly using interrogative pronouns is essential for effective communication, as they allow speakers to gather specific information and engage in meaningful dialogue. They are particularly important in academic settings, interviews, and everyday conversations where information exchange is crucial.

It’s worth noting that interrogative pronouns can sometimes be confused with relative pronouns, which look similar but serve a different grammatical function. While interrogative pronouns ask questions, relative pronouns introduce dependent clauses that provide additional information about a noun in the main clause.
