How does the central idea of a story differ from its theme

The central idea of a story is the main point or topic that the author is trying to convey to the reader. It is typically a broad and general statement that summarizes the overall message or purpose of the work. On the other hand, the theme of a story is a more specific and concrete idea or message that is woven throughout the narrative. Themes often explore recurring motifs, symbols, or ideas that provide deeper insight into the characters, plot, and setting of the story. In other words, the central idea is the main concept or message, while the theme is a more specific exploration or interpretation of that concept.
