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.

Usually the theme of a work of literature can be stated in one word, such as âloveâ or âsolitude.â A work of literature can, and often does, have more than one theme. The theme is generally not stated explicitly in the text, but instead is expressed through the charactersâ actions, words, and thoughts.
