What is trilogy meaning?

A trilogy refers to a set of three literary or artistic works that are related to each other in terms of the characters, themes, or plot. These works can be novels, plays, movies, or musical compositions. Typically, the first work sets the stage and introduces the main characters and themes that are developed throughout the trilogy. The second work deepens and expands upon these themes and characters, and the third work resolves any remaining conflicts and brings the story to a conclusion. The most famous examples of trilogies include J.R.R. Tolkien's "The Lord of the Rings," Suzanne Collins' "The Hunger Games," and Francis Ford Coppola's "The Godfather."
