Third person is a narrative perspective where the storyteller describes events and characters from an outside viewpoint. In this style, the narrator uses pronouns like "he," "she," "they," or "it" to refer to characters, allowing for a broader understanding of the story. This perspective can provide insights into multiple characters' thoughts and feelings. There are different types of third-person narration, including third-person limited and third-person omniscient. In third-person limited, the narrator focuses on one character's experiences, while in third-person omniscient, the narrator knows everything about all characters and events. This flexibility makes third person a popular choice in literature.
