What Is a 10-Book Series Called? (Surprisingly Tricky!)

What’s the Official Name for a 10-Book Series?
Okay, so you've probably heard of a trilogy (three books), a tetralogy (four books), and even a pentalogy (five books). But what about ten books? What do you call that?
The technical term for a 10-book series is a decalogy. (Yep, it sounds fancy.)
The word comes from the Greek "deka" (meaning ten) and "logos" (meaning discourse or story). So, if you ever want to sound super smart at a book club, just drop "decalogy" into the conversation.
Is “Decalogy” Actually Used?
Well… not really. While it’s technically correct, you won’t hear many authors or publishers using it in everyday speech. Most people just say “a 10-book series” or call it a saga, collection, or series—especially in modern publishing.
Honestly, I tried using “decalogy” in a conversation once, and the person just gave me a blank stare. So unless you’re talking to a hardcore literature nerd, you’re probably better off just saying “ten-book series.”

Does a 10-Book Series Need a Special Name?
Not really. While “decalogy” is the fancy term, most authors just call their series a saga or collection. And honestly, that’s probably for the best—imagine having to explain what a "decalogy" is every time someone asks what you're reading.
So, if you’re planning to write (or read) a 10-book series, just call it what feels natural. And if you really want to impress people, throw “decalogy” into a conversation and see what reaction you get.
