What Do Who, Whom, That, and Which Mean?
Each of these relative pronouns has a specific role in sentence structure, depending on what they refer to and how they function within the sentence.
Who
Who is a subject pronoun, used when referring to people performing an action. It answers the question “who is doing something?”:
- The teacher who explained the lesson was very clear. (Who explained? The teacher.)
- Do you know who called earlier? (Who called? Someone did.)
Whom
Whom is an object pronoun, used when referring to the person receiving an action. It answers the question “whom is something being done to?”:
- The student whom the teacher praised was excited. (Who received praise? The student.)
- To whom should I address the letter? (Who is receiving the letter?)
Tip: If you can replace the word with him or her, use whom.
That
That introduces essential clauses and refers to people, animals, or things. It provides information crucial to understanding the sentence:
- The book that she recommended was fantastic. (Essential detail: which book?)
- He’s the person that won the award. (Essential detail: which person?)
In restrictive clauses, that emphasizes necessary information.
Which
Which introduces non-essential clauses, usually referring to things or animals. It adds extra information but doesn’t change the sentence’s core meaning:
- The book, which I borrowed from the library, was fascinating. (Extra detail about the book.)
- His house, which is near the beach, is beautiful. (The house remains identifiable without this detail.)
Tip: Non-essential clauses with which are often set off by commas.
Common Challenges and Mistakes
Many learners confuse who and whom, especially in complex sentences:
- Incorrect: Who did you give the book to? (Should be “whom.”)
- Correct: Whom did you give the book to?
Confusion also arises between that and which:
- Incorrect: The car, that is red, is mine. (Use “which” for non-essential clauses.)
- Correct: The car, which is red, is mine.
Tips for Mastering Who, Whom, That, and Which
To confidently choose the right pronoun, follow these strategies:
- Who vs. Whom: or him/her (object).
- That vs. Which: Use that for essential information and which for extra details.
- Check sentence flow: Remove the clause and see if the core sentence remains clear.
