* Object of a verb: This is the most common use. "Him" receives the action of the verb.
* Example: "The dog chased him." (Him is the object of the verb "chased")
* Object of a preposition: "Him" can follow a preposition like "to," "for," "with," etc.
* Example: "She gave the book to him." (Him is the object of the preposition "to")
* Indirect object: "Him" can be the recipient of something, even if not directly acted upon.
* Example: "He gave him the ball." (Him is the indirect object, receiving the ball)
* Appositive: "Him" can be used to re-identify someone already mentioned.
* Example: "I saw John, him being the tallest one in the room." (Him renames John)
Important Note: "Him" is the objective case pronoun, used for objects of verbs and prepositions. It's the counterpart of "he" (subjective case) which is used for the subject of a sentence.
To understand the function of "him" in a specific sentence, you need to look at the sentence structure and how it relates to other words.
