Introduction
In English, pronouns replace nouns to avoid repetition and streamline sentences. Because they look similar, many learners struggle to decide which one fits a particular spot in a sentence. The pronouns who and whom are interrogative or relative pronouns that specifically refer to persons. The key lies in recognizing whether the pronoun is playing the role of a subject (the doer of the action) or an object (the receiver of the action). This guide will walk you through the grammatical logic, illustrate common patterns, and give you a reliable method for making the right choice.
When to Use Who
Who is used as a subject pronoun. It performs the action of the verb or stands at the beginning of a sentence as the topic. In questions, who asks about the subject, and the answer will be a person who does something.
Examples
- Who called the meeting? (The subject is the person who performed the calling.)
- Who wrote the report? (The subject is the writer.)
- Who is responsible for the project? (The subject is the person holding responsibility.)
In relative clauses, who introduces a clause that describes the subject of the main clause.
- The manager who approved the budget is attending the conference. (Here, who refers to the manager, the subject of the relative clause.)
Quick Checklist for Who
- The pronoun performs the verb.
- It answers the question “who?” in a subject position.
- It follows linking verbs like is, was, seems when describing a subject.
When to Use Whom
Whom serves as an object pronoun. It receives the action of the verb or is the object of a preposition. In questions, whom asks about the object, and the answer will be a person who receives the action Easy to understand, harder to ignore..
Examples
- To whom did you give the presentation? (The object of the preposition to.)
- She asked whom she should invite. (The object of the verb asked.)
- The award was given to whom? (The object of the preposition to.)
In relative clauses, whom introduces a clause that describes the object of the main clause.
- The candidate whom the committee interviewed will be notified soon. (Here, whom refers to the candidate, the object of interviewed.)
Quick Checklist for Whom
- The pronoun receives the verb’s action or follows a preposition.
- It answers the question “whom?” in an object position.
- It often appears after verbs like ask, thank, help, and prepositions such as for, to, with.
Practical Steps to Choose the Right Pronoun
- Identify the sentence type – Determine if the pronoun is the subject or the object.
- Swap with he/ him – If he fits naturally, use who. If him fits, use whom.
- Who called you? → He called you. (Use who)
- Whom did you call? → I called him. (Use whom)
- Check for prepositions – Any preposition directly before the pronoun signals whom.
- The person with whom I spoke is my mentor.
- Read the sentence aloud – If the flow sounds off, reconsider the pronoun choice.
