Foreshadowing is a literary device used by authors to give hints or clues about events that will occur later in a story. This technique helps build anticipation and prepares readers for future developments, creating a sense of suspense. For example, a character finding a mysterious object might suggest its significance later on. In films and literature, foreshadowing can be subtle or overt. It often involves symbols, dialogue, or specific actions that hint at future outcomes. Classic examples can be found in works by William Shakespeare or in movies like The Sixth Sense, where early scenes set the stage for shocking revelations.
