What term refers to the author's main message in a story?

The term that refers to the author's main message in a story is "Theme." The theme represents the underlying idea, insight, or moral that the author wants to convey through the narrative. It is often a universal concept that goes beyond the specific characters or events in the story, allowing readers to connect with broader human experiences and truths.

While plot refers to the sequence of events that occur in the story, characterization focuses on how characters are developed and portrayed within that plot. Setting pertains to the time and place in which the story unfolds. Each of these elements contributes to the overall structure and enjoyment of a story, but they do not encapsulate the central message as effectively as the theme does. Understanding the theme allows readers to engage more deeply with the text, reflecting on its significance and relevance in different contexts.
