If you want to know whether a pronoun is an interrogative pronoun, just ask. No, really! An interrogative pronoun is used when asking questions or finding out more information. Keep reading for the definition of an interrogative pronoun, words that are easily mistaken for interrogative pronouns, and a helpful grammar exercise for practice.
An interrogative pronoun often stands for something you are not aware of yet, because you are asking about it. You use these pronouns specifically to ask questions. The five main interrogative pronouns in English are:
Like all pronouns, interrogative pronouns stand in for a noun. The nouns they stand in for are called antecedents, and the antecedents are the answers to the question. You’ll find interrogative pronouns in sentences like these:
Answer: It is a sweater. (What replaces sweater, the subject in the nominative case)
Answer: The red one is better. (Which replaces the red one, the subject)
The answers to these questions are either people (who/whom/whose) or objects (what/which). In casual writing, which can be used for people. The words whatever, whichever, whoever, and whomever are also considered interrogative pronouns, though they are less common.
When interrogative pronouns appear in sentences that are not questions, they are no longer interrogative pronouns. Instead, they’re relative pronouns, which connect a noun and another clause. Whom, whose, who, and which are relative pronouns, and instead of what, you’d use that.
For example:
These relative pronouns are now linking words, almost (but not exactly) like conjunctions. Keep in mind that even though the interrogative words are present, they are not working as interrogative pronouns in these types of sentences.
It’s easy to mistake interrogative pronouns for interrogative determiners. Unlike pronouns, determiners modify a noun or pronoun that is already provided in the sentence. Whose, what, and which are interrogative determiners when there is a noun or pronoun present.
For example:
These words are no longer acting like pronouns because they are modifying the nouns (shirt, movie, car). Removing the nouns forces the determiners to act like pronouns again. Understanding the difference between interrogative pronouns and interrogative determiners can be the difference between writing open-ended questions and questions with a set number of responses.
There are several other words that start with wh-, but watch out! Not all wh- words are interrogative pronouns. Where, when, why, and how are interrogative adverbs. They modify the verbs in their sentences.
For example:
Where did Andrea go? (where modifies go)
When do you have to wake up tomorrow? (when modifies wake up)
Why are you crying? (why modifies crying)
How does this blender work? (how modifies work)
These interrogative adverbs are important parts of questions, especially because they’re part of the 5 W’s. But they are not interrogative pronouns because they are not pronouns. They don’t replace any nouns in the sentence.
Below are a few examples of interrogative pronouns being used correctly in questions. Notice how they replace nouns in each example, and don’t modify other nouns or verbs.
See if you can identify interrogative pronouns. Determine whether the following sentences include an interrogative pronoun (IP), interrogative determiner (ID), interrogative adverb (IA), or relative pronoun (RP). Be careful: just because it starts with a “w” does not mean it is an interrogative pronoun. The correct answers are listed after the sample sentences.
Check the answers to see if you understand the differences between interrogative pronouns, interrogative determiners, interrogative adverbs, and relative pronouns.
Without interrogative pronouns, you wouldn’t be able to ask for more information or clarifying details. They help people communicate and make sense of the world. To see these pronouns in context, take a look at some examples of interrogative sentences, also known as questions.
