'Whom' is a pronoun that we use when we want to refer to someone in a sentence, and it is also correct in formal writing. 'Whom' is used to refer to the object of a sentence rather than the subject. It is used when referring to a person and is often followed by a preposition, such as 'to,' 'with,' or 'for.' For example, 'Whom did you give the book to?' Instead of using 'who,' which refers to the subject, we use 'whom' because we want to know to whom the book was given. Overall, 'whom' is used in formal writing or situations where accuracy and correctness are emphasized.
