Identify and correct pronoun errors with ‘who’

  • Who is a subject pronoun.
    👉 It is used when the pronoun does the action in the sentence.
  • Example:
    Who is calling me? ☎️

  • Who → Subject (the doer of the action).
  • Whom → Object (receives the action).

📌 Example:
❌ Incorrect: Whom is knocking at the door? 🚪
✅ Correct: Who is knocking at the door?


  • If the pronoun replaces the subject → use Who.
  • If the pronoun replaces the object → use Whom.

👉 Quick Test ✅: Replace with he or him.

  • If “he” fits → use Who.
  • If “him” fits → use Whom.

Example:

  • Who/Whom is going to the party? 🎉
    → He is going. (So ✅ Who)
  • To who/whom should I speak? 💬
    → I should speak to him. (So ✅ Whom)

I don’t know whom is calling.
I don’t know who is calling. 📞

Who do you trust the most?
Whom do you trust the most? 🤝


✨ Always check if the pronoun is doing the action (use Who).
✨ If it receives the action, use Whom.
✨ In casual speech, people often use Who instead of Whom, but in formal writing (like exams 📝), use the correct form!


🌈 Summary:

  • Use Who = subject.
  • Use Whom = object.
  • Test with he/him to check.
