Episode

An episode (from Greek ἐπεισόδιον epeisodion, “parenthetic addition”) is a part of a dramatic work such as a serial television or radio program. An episode is a part of a sequence of a body of work, akin to a chapter of a book. The term sometimes applies to works based on other forms of mass media as well, as in Star Wars. Episodes of news programs are also known as editions.
