Expert writing Tips
Best practice
Use "whom" when it is the object of a verb or preposition in formal writing. If you're unsure, try replacing "whom" with "him" or "her"; if it fits, "whom" is correct.
Common error
Avoid using "whom" when "who" is grammatically correct. "Who" is used when referring to the subject of a sentence, while "whom" is used for the object. Simplify your sentences if unsure.

FAQs
How do I decide whether to use "who" or "whom"?
Use "who" when the pronoun is the subject of the clause and "whom" when it is the object of a verb or preposition. If you can replace it with "him" or "her", use "whom"; otherwise, use "who".
Is it correct to use "whom" at the beginning of a sentence?
Yes, it is correct to use "whom" at the beginning of a sentence, especially in questions where "whom" is the object of a verb or preposition. For example, "To whom should I address this letter?".
What are some common phrases that use "whom"?
Common phrases include "to "whom it may concern"", "by "whom"", "for "whom"", and "with "whom"".
Can I use "who" instead of "whom" in modern English?
While "whom" is technically correct in certain contexts, many people now use "who" in all but the most formal writing or speech. However, using "whom" correctly demonstrates a strong command of grammar.
