# Say "quadyssey", not "quadrilogy".

"Trilogy" is a delightful word.

["Quadrilogy"](https://en.wikipedia.org/wiki/Tetralogy#Other_information) is a
blight of the tongue.

["Tetralogy"](https://en.wikipedia.org/wiki/Tetralogy) is clunky.
["Quartet"](https://en.wikipedia.org/wiki/Tetralogy#Other_information) is broad.

I propose the following word:

> **quad•ys•sey** _(kwŏd′ĭ-sē) noun_
>
> _a work of art composed of four distinct works_

## Notable Quadysseys

Quadysseys seem to be rare.

Please [email me](mailto:hello@taylor.town) if you can vouch for good candidate
series.

- [Hyperion Cantos](https://en.wikipedia.org/wiki/Hyperion_Cantos)
- [The Inheritance Cycle](https://en.wikipedia.org/wiki/The_Inheritance_Cycle)
- [Long Price Quartet](https://www.tor.com/2011/04/19/fantasy-for-grown-ups-daniel-abrahams-long-price-quartet/)

## Plus Ones

Adding a sequel or prequel to a trilogy does not make it a quadyssey.

- [Divergent + Four](https://en.wikipedia.org/wiki/Divergent_%28book_series%29)
- [Lord of the Rings + The Hobbit](https://en.wikipedia.org/wiki/The_Lord_of_the_Rings)
- [The Matrix + Resurrections](https://en.wikipedia.org/wiki/The_Matrix_%28franchise%29)

## Polygies

Furthermore, I would change the rest of
[wiktionary's trilogy companions](https://en.wiktionary.org/wiki/tetralogy):

- duology
- trilogy
- quadyssey ~~quadrilogy~~
- polygy ~~pentalogy~~
- polygy ~~hexalogy~~
- polygy ~~heptalogy~~
- polygy ~~octalogy~~
- polygy ~~ennealogy~~
- polygy ~~decalogy~~
- polygy ~~polylogy~~

For example, [Harry Potter](https://en.wikipedia.org/wiki/Harry_Potter) is a
7-part polygy and
[A Series of Unfortunate Events](https://en.wikipedia.org/wiki/A_Series_of_Unfortunate_Events)
is a 13-part polygy.
