Expert writing Tips

Best practice

In formal writing, always use "with whom" instead of "with who". This demonstrates attention to grammatical correctness and enhances credibility.

Common error

Remember that "who" acts as a subject, while "whom" acts as an object. If you can replace "who/whom" with "he/she", use "who". If you can replace it with "him/her", use "whom".

Ludwig's WRAP-UP

In summary, while the phrase "with who" is frequently used, particularly in informal contexts and media, it is grammatically incorrect. The correct form is "with whom". As Ludwig highlights, using "with whom" in formal writing shows attention to grammatical correctness. When choosing between "who" and "whom", remember to use "whom" when it functions as the object of a preposition. Despite its common occurrence, aiming for grammatical precision will improve clarity and credibility.

FAQs

Is it correct to say "with who" or "with whom"?

The grammatically correct phrase is "with whom". "Who" is a subjective pronoun, while "whom" is an objective pronoun. In this case, the pronoun functions as the object of the preposition "with".

When should I use "with whom" instead of "with who"?

Use "with whom" in formal writing and when the pronoun is the object of a preposition. In informal speech, "with who" is sometimes used, but it's not grammatically correct.

What are some alternatives to using the phrase "with whom"?

Depending on the context, you can rephrase the sentence to avoid using "with whom" altogether. For example, instead of "The person with whom I spoke", you could say "The person I spoke with".

How can I easily remember when to use "who" vs. "whom"?

A helpful trick is to substitute "he/she" for "who" and "him/her" for "whom". If "he/she" fits, use "who". If "him/her" fits, use "whom".
