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.
In literature, theme refers to the main idea or moral of the story. Sometimes this main idea or moral is stated directly, and sometimes the reader has to think about the main idea. In most literary works, there could be more than one theme. Novels and plays, especially, are long enough that different readers could pick up on different thematic ideas throughout. It is best to state the theme in a sentence.
