One of the most common dilemmas in English grammar is deciding when to use "who" and when to use "whom." Although it might seem tricky, understanding the difference between these two words can significantly enhance the clarity and professionalism of your writing. This blog post will break down the rules and provide some easy tips to help you master the use of "who" and "whom."
Basic English Grammar Rules
**"Who"** is a subject pronoun, similar to "he," "she," or "they." It refers to the subject of a sentence—the person performing the action.
**"Whom"** is an object pronoun, similar to "him," "her," or "them." It refers to the object of a sentence—the person receiving the action.
Simple Rule: Subject vs. Object
To decide whether to use "who" or "whom," determine if the word is functioning as a subject or an object in the sentence.
**Use "who" when:**
- You are referring to the subject of the sentence.
- The subject is performing the action.
**Use "whom" when:**
- You are referring to the object of the sentence.
- The object is receiving the action.
Examples
- **Who** is going to the store? (Here, "who" is the subject performing the action of going.)
- To **whom** should I address the letter? (Here, "whom" is the object receiving the action of addressing.)
The He/Him Test
One of the easiest ways to determine whether to use "who" or "whom" is the **he/him test**. Replace "who" or "whom" with "he" or "him" in the sentence. If "he" fits, use "who." If "him" fits, use "whom."
- He/Who is going to the store? (He is going to the store. Therefore, use "who.")
- To him/whom should I address the letter? (To him should I address the letter. Therefore, use "whom.")
More Examples with Explanations
1. **Who/Whom** is responsible for this project?
- He is responsible for this project. (He = who)
- Correct: **Who** is responsible for this project?
2. The manager, **who/whom** I respect greatly, is leaving the company.
- I respect him greatly. (Him = whom)
- Correct: The manager, **whom** I respect greatly, is leaving the company.
3. **Who/Whom** did you invite to the party?
- You invited him to the party. (Him = whom)
- Correct: **Whom** did you invite to the party?
4. She is someone **who/whom** I think will succeed.
- I think she will succeed. (She = who)
- Correct: She is someone **who** I think will succeed.
When in Doubt
While "whom" is technically correct in many formal contexts, it's worth noting that in casual conversation, "who" often replaces "whom." However, in formal writing or when striving for grammatical precision, using "whom" correctly can make a positive impression.
Mastering the use of "who" and "whom" is all about understanding their roles as subject and object pronouns. By applying the simple rules and the he/him test, you can confidently choose the correct pronoun and enhance the clarity and professionalism of your writing. With a bit of practice, using "who" and "whom" correctly will become second nature. Happy writing!
