The document discusses the uses of object pronouns in English. It begins by explaining what an object pronoun is, using the example sentence "Jenny loves Jack". It analyzes this sentence to identify the action (to love), who performs the action (Jenny), and who receives the action (Jack). It then replaces the names Jenny and Jack with the subject pronoun "she" and object pronoun "him", respectively. The document continues by listing the English object pronouns and providing examples of how they can be used as direct objects and within prepositional phrases.
