Google has answered A parody is a composition that imitates the style of another composition, normally for comic effect and often by applying that style to an outlandish or inappropriate subject. Seth Grahame-Smith's Pride and Prejudice and Zombies is a perfect example of parody. Grahame-Smith took Jane Austen's text and introduced zombies into the storyline. Throughout the reworked novel, he maintained Austen's writing style, voice, and even much of the original storyline, creating a new work that is recognizable as being Jane Austen's but that definitely isn't. A satire, on the other hand, is intended to do more than just entertain; it tries to improve humanity and its institutions. A satire is a literary work that tries to arouse the reader's disapproval of an object — a vice, an abuse, a faulty belief — by holding it up to ridicule. Satirists use euphemism, irony, exaggeration, and understatement to show, with a greater or lesser degree of levity, the follies of mankind and the paradoxes and idiocy that they can lead to.
