Understanding how to correctly use who, whom, and which is an essential grammar skill for all learners. These words are known as relative pronouns, and they help connect ideas, describe people or things, and create complex sentences.
What Are Relative Pronouns?
Relative pronouns are words that connect a dependent clause to a noun and give more information about that noun.
The worksheet focuses on three relative pronouns:
- Who – refers to people (subject)
- Whom – refers to people (object)
- Which – refers to things/animals (non-human nouns)
These pronouns help improve writing, create detailed descriptions, and join ideas smoothly.

Your worksheet includes all these types of sentences.
