Definition
A trope is a common or overused theme or device; a figurative or metaphorical use of a word or expression. Think of it as a recurring pattern or a shortcut in storytelling. Tropes aren't necessarily bad. They are the building blocks of many narratives. Some examples are 'the chosen one' or 'the damsel in distress.' However, overusing them can make a story predictable. Sometimes subverting a trope can be a source of creativity.
