Expert writing Tips
Best practice
In formal writing or legal contexts where precision is crucial, "with which person" may be appropriate to avoid ambiguity. However, consider if "with whom" is a more familiar and equally precise alternative.
Common error
Don't mistakenly use "who" instead of "whom" after the preposition "with". "Whom" is the objective case and is grammatically correct after a preposition. While "with who" might be heard in informal speech, it's not appropriate for formal writing. Opt for the correct pronoun or rephrase the sentence to avoid the issue altogether.
