sequel

A sequel, at its heart, is something that comes after an earlier work and continues it in a direct way. Most often, we use the word in entertainment and storytelling: books, movies, plays, television series, and video games. A sequel usually returns to the same story world and carries forward the plot, characters, or ideas introduced before. Think of The Empire Strikes Back as a sequel to Star Wars: A New Hope, or Toy Story 2 as a sequel to Toy Story.

There is also a more formal use of sequel in medicine and careful writing. In that sense, it can mean a condition or result that follows from an earlier disease, injury, or event. A doctor might speak of memory loss as a sequel of a head injury. In formal writing, it can also mean an outcome that naturally follows something else, though this use is much less common in everyday conversation.

The word comes from the Latin sequi, meaning "to follow." It implies that the second event or work is dependent on, and builds upon, what came before. It's not simply a related story; it is a direct continuation. A prequel, by contrast, tells a story that precedes the original—setting the stage for events we already know.

So, if you're waiting for the next film in a series, the next novel in a story, or reading about a condition caused by an earlier illness, the idea stays the same: a sequel is something that follows and grows out of what came before.
