Prequel Prequel A prequel is a literary, dramatic, or cinematic work whose story precedes that of a previous work, by focusing on events that occur before the original narrative. A prequel is a work that forms part of a backstory to the preceding work. All "prequels" are, by definition, essentially sequels in that they "expand on a "previous" or "preceding" work." The term is a 20th-century neologism that is a portmanteau of the prefix "pre-" (from Latin "prae", "before") and "sequel". Like other sequels, prequels may or may not concern the same plot as the work from which they are derived.
