1. Themes are expressed and emphasized by the way the author makes us feel. By sharing feelings of the main character you also share the ideas that go through his mind.
2. Themes are presented in thoughts and conversations. Authors put words in their character’s mouths only for good reasons. One of these is to develop a story’s themes. The things a person says are much on their mind. Look for thoughts that are repeated throughout the story.
3. Themes are suggested through the characters. The main character usually illustrates the most important theme of the story. A good way to get at this theme is to ask yourself the question, what does the main character learn in the course of the story?
4. The actions or events in the story are used to suggest theme. People naturally express ideas and feelings through their actions. One thing authors think about is what an action will “say”. In other words, how will the action express an idea or theme?
A symbol might be a specific object or person that has deeper meaning but a theme is usually carried throughout the book and is about life, society, or human nature. They explore timeless or universal ideas and are usually implied (which might make them harder to identify but easier to argue.
It is important to recognise the difference between the theme of a literary work and the subject of a literary work. The subject is the topic on which an author has chosen to write. The theme, however, makes some statement about or expresses some opinion on that topic. For example, the subject of a story might be war while the theme might be the idea that war is useless.
