Who and Whom

The Quick Answer
What is the difference between who and whom?

Who is like he because it is used as the subject of a verb. For example:
  • Who likes milk in tea?
  • (Compare this with "He likes milk in tea.")
Whom is like him because it is used as an object. (It is never the subject of a verb.) For example:
  • Sarah saw whom on the bus?
  • (Compare this with "Sarah saw him on the bus.")

Who Is the Subject of a Verb

The word who can only be used when it is the subject of a verb. If you don't know what that means, it just means it is like the words I, he, she, we, and they. Just like who, these words are used as subjects.

Confusing who and whom is like confusing I and me or he and him. Here they all are in a table:

Examples of Who and Whom in Sentences

Here are some examples of who and whom in sentences:
  • Who paid for the meal?
  • (Who is the subject of the verb to pay.)

  • I have not seen the man who lives in the hut by the beach for a week.
  • (Who is the subject of the verb to live.)

  • I wonder who is in charge.
  • (Who is the subject of the verb to be, i.e., who is.)

  • Sarah gave the tickets to who?
  • (This is wrong. Sarah is the subject of gave. Who is not the subject of any verb. Therefore, you cannot use who. It should be whom. This is like saying "Sarah gave the tickets to he.")

  • Do you know the boy who rang the bell?
  • (Who is the subject of rang.)

Real Life Examples of People Using Whom Incorrectly

Often, you have to look closely at your sentence to see whether who is the subject of a verb. Here are two real-life examples of people getting it wrong:
  • If you notice any faulty office equipment or hazards, please report them to your supervisor whom will notify the management.
  • (This is wrong. It should be "who will notify the management".)
Here is a slightly more complicated example from a TV magazine. The use of whom is incorrect because it is the subject of existed.

This should be "...madman who the authorities refused to admit existed".)

Whom Is Never the Subject of a Verb

Whom is like him, her, and them because it is never the subject of a verb. Whom is an object. For example:

Examples of Whom in Sentences

  • Claire kissed whom yesterday?
  • (Here, whom is the direct object of the verb kissed.) 

  • You gave the parcel to whom?
  • (Here, whom is the indirect object of the verb gave.)

  • You sat by whom all night?
  • (Here, whom is the object of the preposition by.) 

  • She is a wistful recluse whom lives near the river.
  • (Remember, whom cannot be the subject of a verb. This should be "who lives".)
"John told Jackie your secret."



    "No, I asked whom not who."

Whom after Prepositions

Always use whom after prepositions. (Prepositions are words like to, with, by, on, in, near.). In the examples below, the prepositions are in bold.
  • You have a child by whom?

  • With whom did you see Janice?

  • That is the lady to whom I made the promise.

  • That is the lady whom I made the promise to.
  • (Some writers like to avoid ending a sentence in a preposition and construct their sentences like the one above. Remember, the preposition still governs whom.)
Here is an example of an estate agent forgetting that whom follows a preposition:

(This should be "BY WHOM?".)

A Joke That Misuses Who

Here is a joke from a student comic that misuses who:

It should be "Two hits to whom?".
