What Do You Call a Series of 4?

In the realm of literature, a series of works hold significant importance. Whether it guides us through an epic journey, explores different stages of a character’s life, or simply spreads a comprehensive narrative across multiple books. But, how do we refer to a series of four works? Simply put, it’s called a tetralogy.

Understanding Series

To begin with, it’s essential to understand the Greek or Latin numeral prefixes and their application in terms of literature series:

  • Dilogy: Refers to a series of two related works.
  • Trilogy: A term commonly used to indicate a series of three works.
  • Tetralogy: The name given to a series of four works. Alternative terms include ‘Quartet’ or ‘Quadrilogy’.
  • Pentalogy: Stands for a series of five parts or books.

As the series increases, it follows Greek numeral prefixes like hexalogy (6), heptalogy (7), octalogy (8), ennealogy (9), decalogy (10), etc.
