Trope, Subversion, Parody: What's the difference?

I see lots of posts on here that use the words "trope," "subversion," and "parody," but not everyone seems to use the same terminology. <br><br>Here's my attempt to explain each of these terms, along with an example of each for the "Chosen One" trope. If you disagree with my explanation, or if you have any questions, please let me know. I have italicized the definition of each term. <br><br>Trope: A *common or overused theme or device*, a short hand way of communicating to the audience. Harry Potter is the chosen one who saves the world because of special powers he doesn't control, and the help of loyal companions. He must defeat the dark lord because of a prophecy. <br><br>Subversion: A *story that sets up a trope, then gives that trope to a character who doesn't quite fit the normal mold*, often for the purpose of social commentary. In this example, Harry Potter is the chosen one, but rather than being "The Boy Who Lived" because of prophecy, he's actually the chosen one because he's the illegitimate child of a politician. The prophecy is a bunch of nonsense designed to make him sound more impressive. <br><br>Parody: *A trope that has been exaggerated and distorted for comedic effect.* This story takes place in a world where every few years, a new "chosen one" appears. The chosen ones are all children whose mothers were visited by an angel at the moment of conception, and who all have exactly twelve companions. Since this happens about every ten years or so, the world has about six chosen ones at any given time, none of whom are able to save the world. <br><br>For those of you who are confused about how to structure a chosen one story, I hope this helps you!
