A narrator is the voice that tells a story in books, movies, or plays. This person can be a character in the story, like Harry Potter, or an outside observer who knows everything about the characters and events. The narrator helps guide the audience through the plot, sharing thoughts and feelings that add depth to the story. There are different types of narrators, such as first-person, who uses "I" and shares personal experiences, and third-person, who uses "he" or "she" to describe others. Each type shapes how we understand the story and connect with characters like Elizabeth Bennet or Frodo Baggins.
