Foreshadowing is a literary technique used by writers to give hints or clues about what will happen later in a story. This can create suspense and keep readers engaged, as they try to piece together the hints. For example, if a character named John finds a mysterious key early in the story, it might suggest that he will unlock something important later on. Writers often use foreshadowing through dialogue, actions, or even symbols. For instance, if a storm is brewing in the background while Sarah is making a big decision, it could indicate that trouble is ahead. This technique helps build anticipation and enriches the storytelling experience.
