Theme is defined as a main idea or an underlying meaning of a literary work that may be stated directly or indirectly. Major and minor themes are two types of themes that appear in literary works. A major theme is an idea that a writer repeats in his work, making it the most significant idea in a literary work. A minor theme, on the other hand, refers to an idea that appears in a work briefly and gives way to another minor theme.
The theme of any literary work is the base that acts as a foundation for the entire literary piece. The theme links all aspects of the literary work with one another and is basically the main subject. The theme can be an enduring pattern or motif throughout the literary work, occurring in a complex, long winding manner or it can be short and succinct and provide a certain insight into the story.
