Answer:
Foreshadowing is an advance sign or warning of what is to come in the future. ... Foreshadowing is used as a literary device to tease readers about plot turns that will occur later in the story. A fortune teller might use foreshadowing, warning that a short life line is a sign of some impending disaster.
Examples of Foreshadowing: 1. A pipe is going to burst, but before it does, the author writes a scene where the family notices a small dark spot on the ceiling, but ignores it.
