The narrator is the voice or character that tells a story in a book, film, or other forms of media. This character can be a participant in the story or an outside observer. The narrator's perspective shapes how the audience understands the plot and characters, influencing their emotional connection to the narrative. There are different types of narrators, such as first-person, where the narrator uses "I" and shares personal experiences, and third-person, which uses "he," "she," or "they" to describe events from an outside viewpoint. The choice of narrator affects the tone and style of the story.
