Best practice

Avoid using the phrase "whom of which" in your writing. It's generally considered grammatically incorrect. Use "of whom" or "of which" depending on whether you are referring to people or things.

Ludwig's WRAP-UP

In summary, the phrase "whom of which" is generally considered grammatically incorrect in standard English. As Ludwig AI explains, it's not a correct and usable phrase. The individual words "whom" and "which" are relative pronouns, but their combination in this order doesn't form a valid construction. It's advisable to use either "of whom" when referring to people or "of which" when referring to things. Due to its ungrammatical nature, this phrase is inappropriate for any formal context and should be avoided to maintain clarity and credibility in writing.

FAQs
