What is the purpose of a foreshadowing device in literature?

A foreshadowing device serves the important purpose of providing readers with subtle hints or clues about future events in the narrative. This technique enhances the reader's experience by creating anticipation and suspense. When foreshadowing is effectively utilized, it can build tension and prepare the audience for significant developments, allowing them to engage more deeply with the story as they pick up on these clues.

In contrast, while explaining character motivations is crucial for character development, this is not the primary role of foreshadowing. Creating a vivid setting contributes to the atmosphere of a story, but this is distinct from foreshadowing, which focuses on indicating future plot points. Introducing new characters is an essential narrative function but does not connect with the idea of foreshadowing, as it doesn't provide hints about events that are to come. Thus, the focus of foreshadowing specifically aligns with giving insight into what might unfold later in the plot.
