How does "foreshadowing" function in a story?

Foreshadowing is a literary device used by authors to provide hints or clues about events that may occur later in the narrative. This technique helps to build anticipation and prepares readers for what is to come, creating a sense of suspense or tension. By subtly introducing these hints within the early parts of the story, foreshadowing can enrich the reader's experience and make the unfolding events more impactful. It allows readers to engage with the story on a deeper level, as they may start predicting outcomes based on the clues given, which adds to their overall enjoyment and understanding of the narrative arc.
