A third-person narrator is a storytelling perspective where the narrator is not a character in the story. Instead, they observe and report on the events, thoughts, and feelings of the characters from an outside viewpoint. This type of narration can provide a broader understanding of the plot and the motivations of multiple characters. There are two main types of third-person narration: third-person limited and third-person omniscient. In third-person limited, the narrator focuses on the thoughts and experiences of one character, while in third-person omniscient, the narrator knows everything about all characters and events. This flexibility allows for varied storytelling techniques.
