If you’ve ever paused before writing who to contact or whom to contact, you’re not alone. This is one of the most common grammar questions—and the good news is, it’s easier than it looks.
Here’s the simple truth: whom to contact is technically correct, but who to contact is more common and widely accepted in modern English.
Quick Answer: Who to Contact or Whom to Contact
- Whom to contact ✅ Grammatically correct (formal)
- Who to contact ✅ Common and acceptable (modern usage)
- Use who in everyday writing and speech
Example:
- Do you know who to contact?
- Please tell me whom to contact. (more formal)
Understanding the Rule: Who vs Whom
The difference comes down to subject vs object.
- Who = subject (does the action)
- Whom = object (receives the action)
In the phrase:
- “contact” is the verb
- The person being contacted is the object
So technically:
- whom to contact ✅
Why “Whom to Contact” Is Correct
Let’s expand the sentence:
- You should contact him → object
- Replace “him” → whom
So:
- whom to contact = correct
Example:
- I don’t know whom to contact.
Why “Who to Contact” Is Still Used
In modern English:
- who is often used instead of whom, even in object positions
- It sounds more natural in everyday conversation
Example:
- Do you know who to contact? (very common)
