The document discusses the concept of theme in literary works. A theme is the main idea or underlying meaning, which can be stated or implied. It differs from the subject or topic by making a statement about the topic. Themes can be major, returning throughout a work, or minor. While the subject is the topic, the theme expresses an opinion on that topic. Themes are conveyed through how the author makes the reader feel, thoughts and conversations of characters, the main character, and the actions in the story.
