👉 The "whom" fluid refers to the object of a verb or preposition in a sentence, specifically when the object is not the subject but rather the recipient of the action. It's used to clarify the relationship between the subject and the object, making the sentence structure clearer. For example, in "She gave him a book," "him" is the whom fluid because it indicates that "him" is receiving the book, not performing the action of giving. This distinction helps avoid ambiguity and ensures the sentence conveys the intended meaning accurately.
