What does "exposition" refer to in a literary plot structure?

Exposition is an essential part of a literary plot structure that plays a crucial role in establishing the foundation for the story. It involves the introduction of characters, settings, and the initial situation within the narrative. By providing this background information, the exposition helps readers understand who the characters are, where the story takes place, and what the circumstances are that may influence the plot's progression.

This introduction is vital as it sets the stage for the events that will unfold later in the narrative, such as the rising action and climax. Without a solid exposition, readers might struggle to grasp the motivations of the characters or the significance of the events that occur thereafter. Thus, the exposition significantly enhances readers' comprehension and engagement with the story.
