Who vs Whom: Grammar Rule You Can Actually Remember

by | Jul 4, 2025 | Career Development

The difference between who and whom is a common dilemma for English learners who aim for grammatical precision in their writing and speaking. Understanding when to use ‘who’ or ‘whom’ can significantly enhance clarity and correctness in your communication.

Understanding the Basics of ‘Who’ and ‘Whom’

‘Who’ and ‘whom’ are both pronouns, but they serve different functions within a sentence. ‘Who’ acts as the subject, while ‘whom’ functions as the object. Simply put, if you’re talking about the doer of an action, use ‘who.’ Conversely, if you’re referring to the person who is receiving the action, use ‘whom.’

Examples of ‘Who’ and ‘Whom’ in Sentences

Pronoun Example Sentence
Who Who is going to the party?
Whom Whom did you invite to the party?

Notice that in the case of ‘who,’ it is used to ask about the person performing the action of going to the party. Conversely, ‘whom’ is used to question the person receiving the action of being invited.

Using ‘Who’ in Relative Clauses

‘Who’ is commonly used in relative clauses to provide more information about a subject:

Example: The teacher who assigned the homework is absent today.

In this example, ‘who’ introduces a relative clause that describes which teacher is being referred to.

Using ‘Whom’ in Relative Clauses

‘Whom’ can also introduce relative clauses but acts as the object within that clause:

Example: The student whom you met yesterday is in my class.

Here, ‘whom’ is used because the student is the object of the action of meeting.

Common Missteps with Who and Whom

A frequent mistake is using ‘who’ where ‘whom’ is correct. To determine the appropriate pronoun, ask yourself whether the pronoun is the subject or the object of the verb. If you can replace the pronoun with ‘he’ or ‘she,’ ‘who’ is correct. If ‘him’ or ‘her’ fits better, use ‘whom.’ For a deeper understanding, refer to the Merriam-Webster guide on who vs. whom.

Advanced Tips for Mastery

Practice is essential for mastering the use of ‘who’ and ‘whom.’ Try to use them correctly in sentences that you create, and ask for feedback from proficient English speakers. Additionally, test your understanding and get real-time feedback by utilizing resources like the GET Global English Test.

Deciding Between ‘Who’ and ‘Whom’ with Confidence

For complex sentences, break them down into smaller parts to identify the main subject and object. This analytical approach will help you decide with confidence. For more examples and practical exercises, the Cambridge Dictionary offers valuable insights into using these pronouns correctly.
