As discussed in this other english.SE post, dilogy/duology/etc. can be used to describe a series of two items, and trilogy and tetralogy exist for three- and four-item series, but I couldn't find any words for series with more than four items.

Specifically, I'd like to see words for up to eight-length series. (The thought came about when trying to find a word other than saga/series/etc. to describe the Harry Potter book and movie series.)


1 Answer 1


How about just continuing the series?

Trilogy, tetralogy, pentalogy, hexalogy, heptalogy, octalogy, etc.

    @alwayslearning Good point. What's going on here is that -logy" means oral or written expression (Merriam-Webster), and penta-, hexa-, etc. are from the Greek for five, six, etc. Note that NVZ was kind enough to add links to my answer. NVZ, thank you. Much appreciated. I need to learn how to do that better. I'm still -- and always -- learning also. :-) Commented Aug 28, 2016 at 17:11
  • @RichardKayser you can add links like this: [title](link). For example, [Google](google.com)

  • Thanks Richard, exactly what I was looking for! Now back to the Harry Potter octalogy of movies :P Commented Aug 28, 2016 at 18:39
  • @DolanAntenucci Enjoy! The best octalogy of all time? :-) Commented Aug 28, 2016 at 18:51
  • Shouldn't it be spelled octology, the prefix being octo-? Wiktionary has it wrong, but usage seems to get it right. Commented Feb 5, 2017 at 13:22
