Who and whom are pronouns that often create confusion in English grammar. Both words refer to people, but they have different roles in a sentence. Simply put, “who” is used as a subject pronoun, while “whom” is used as an object pronoun. The key difference lies in their positions within a sentence: “Who” is used when referring to the subject performing the action, and “Whom” is used when referring to the object receiving the action. Let’s explore more about who vs whom.
Basic Definitions of Who:
- “Who” is a pronoun used to refer to the subject of a sentence or clause.
- It is used when asking about the person who is performing an action or when referring to the person doing something.
- Example: Who is going to the party? (Here, “who” refers to the subject or the person performing the action of going to the party.)
Basic Definitions of Whom:
- “Whom” is a pronoun used to refer to the object of a verb or a preposition.
- It is used when asking about the person who is receiving the action or when referring to the person being acted upon.
- Example: To whom did you give the book? (Here, “whom” refers to the object or the person receiving the action of giving the book.)
Who vs Whom
Here’s a table highlighting the main differences between “who” and “whom”:
| Who | Whom | |
|---|---|---|
| Function | Subject pronoun | Object pronoun |
| Usage | Used when referring to the subject of a sentence or clause, the person performing the action | Used when referring to the object of a verb or a preposition, the person being acted upon |
| Example | Who is going to the party? (Subject) | To whom did you give the book? (Object) |
| Position in Sentence | Used at the beginning or middle of a sentence | Used after a preposition or as an object at the end of a sentence |
| Replacement | Can be replaced with he/she/they | Can be replaced with him/her/them |
When to Use “Who”:
“Who” is used when referring to the subject of a sentence or clause, specifically the person performing the action. Here are a few simple guidelines to help you understand when to use “who”:
1. Subject of the Sentence: Use “who” when the person being referred to is the subject of the sentence.
Example: Who is knocking on the door? (The person knocking is the subject of the sentence.)
2. Asking Questions: Use “who” when asking about the person performing an action.
Example: Who ate the last slice of pizza? (Asking about the person who performed the action of eating.)
3. Replacing with He/She/They: If you can substitute “who” with “he,” “she,” or “they” in the sentence, then you are using it correctly as a subject pronoun.
Example: Sarah is the one who won the race. (Sarah won the race. She won the race.)
When to Use “Whom”:
“Whom” is used when referring to the object of a verb or a preposition, specifically the person being acted upon. Here are a few simple guidelines to help you understand when to use “whom”:
1. Object of the Verb: Use “whom” when the person being referred to is the object of a verb.
Example: I saw the girl whom I met yesterday. (The girl is the object of the verb “met.”)
2. Object of the Preposition: Use “whom” when the person being referred to is the object of a preposition.
Example: To whom did you give the gift? (The person receiving the gift is the object of the preposition “to.”)
3. Replacing with Him/Her/Them: If you can substitute “whom” with “him,” “her,” or “them” in the sentence, then you are using it correctly as an object pronoun.
Example: The teacher praised the students whom she admired. (The teacher praised them. She admired them.)
Common Mistakes to Avoid when using “Who” and “Whom”:
1. Using “Who” Instead of “Whom”:
Incorrect: Who did you give the book to?
Correct: Whom did you give the book to?
Explanation: In this sentence, “whom” is the correct choice because it functions as the object of the preposition “to.”
2. Using “Whom” Instead of “Who”:
Incorrect: To whom is knocking on the door?
Correct: Who is knocking on the door?
Explanation: “Who” is used as the subject of the sentence, not the object of the preposition “to.”
3. Incorrect Placement of “Who” or “Whom”:
Incorrect: The girl whom won the race is my friend.
Correct: The girl who won the race is my friend.
Explanation: “Who” should be placed immediately after the noun it refers to, in this case, “girl.”
4. Ambiguous Sentences and Resolving Confusion:
Incorrect: I met a person whom is very talented.
Correct: I met a person who is very talented.
Explanation: In this sentence, “who” is the correct choice because it refers to the subject of the verb “is.” Using “whom” in this context can lead to confusion.
