Confused about using 'who' or 'whom' in questions and sentences

Asked byClaire CopydeskPosted Apr 2, 2026 10:06 PM3 answers22 upvotesCanonical URL

I'm always unsure about when to use 'who' versus 'whom' in my writing. For example, if I want to ask, "Who did you see at the store?" or should it be "Whom did you see at the store?" Another one that confuses me is, "Who should I give this book to?" or is it "Whom should I give this book to?"

I've seen both forms used, and I'm not sure which one is actually correct in these situations. Can someone explain how to choose the right word with some clear examples? Thanks!

Context:
I'm writing emails and essays for school in the US and want to sound more formal.

Writers often memorize a definition but miss the context cue that controls the correct choice.This helps you choose wording by meaning instead of surface form.A different phrasing is better when the literal meaning would be clearer.Did I choose this form for meaning, not because it looked familiar?

To choose between 'who' and 'whom', remember this pattern: 'Who' acts as the subject of a sentence or clause, while 'whom' functions as the object.

  • Who = replaces subjects like 'he' or 'she'.
  • Whom = replaces objects like 'him' or 'her'.

Examples:

  1. "Who called you yesterday? — He called me." ('Who' is doing the action.)
  2. "Whom did you invite? — You invited him." ('Whom' is receiving the action.)

Practice: Try replacing 'who' or 'whom' with 'he/she' or 'him/her':

  • "___ should I consult?" → "Should I consult him?" → 'Whom should I consult?'
  • "___ is attending the meeting?" → "He is attending the meeting." → 'Who is attending the meeting?'

Self-edit tip: If you can answer with 'him' or 'her', use 'whom'. If 'he' or 'she' fits, use 'who'.

Apply this to your sentences:

  • "___ did you see at the store?" → "You saw him at the store." → 'Whom did you see at the store?'
  • "___ should I give this book to?" → "I should give this book to him." → 'Whom should I give this book to?'

You can decide between 'who' and 'whom' by mentally switching them with 'he/she' or 'him/her.'

Step-by-step substitution:

  • If 'he' or 'she' fits, use 'who.'
  • If 'him' or 'her' fits, use 'whom.'

Example Comparison:

  1. 'Who/Whom did Sarah ask to join?' → Sarah asked him to join. (Use 'whom')
  2. 'Who/Whom wants dessert?' → He wants dessert. (Use 'who')

Quick self-edit:

  • Try mentally replacing the word. "Did Sarah ask him?" → 'Whom did Sarah ask?'
  • "He wants dessert." → 'Who wants dessert?'

Practice Sentence: Fill in the blank and check your substitution:

  • "___ do you trust with your secrets?" (You trust him → 'Whom')

Understanding 'who' versus 'whom' is all about their grammatical roles. 'Who' functions as a subject; 'whom' as an object.

Contrast these pairs:

  • 'Who is coming to the party?' (Here, 'who' is the subject, like 'she is coming.')
  • 'Whom did you meet at the party?' (Here, 'whom' is the object, like 'you met him.')

Another pair:

  • 'Who is responsible for this project?' ('Who' = subject)
  • 'To whom should I address the letter?' ('Whom' = object of the preposition 'to')

Tip for Editing: If you are unsure, rephrase your question into a statement and see whether 'he/she' or 'him/her' fits. For example: 'Did you meet him at the party?' — 'Whom did you meet at the party?'

Try these:

  • "___ will lead the meeting?"
  • "For ___ did you buy this gift?"

Choose:

  • 'Who' or 'Whom'?

Focus on the word's grammatical job in the sentence.
