...because 'duology' is NOT a real word according to the dictionary!

'Trilogy' is
'Tetralogy' is

nothing for 2??

Oh, and yes, I did a Google search and there were some forums that said the correct term was called 'dilogy' but in searching the dictionary, 'dilogy' means:

Dil"o*gy\, n.; pl. Dilogies. [L. dilogia, Gr. ?, fr. ? doubtful; di- = di`s- twice + ? to speak.] (Rhet.) An ambiguous speech; a figure in which a word is used an equivocal sense. [R.]

so yeah, not what I'm looking for. LOL

'dilogy' doesn't even exist in the Merram Webster dictionary.

So does such a word exist for a 2-book series?

 

[Caddy]

Gosh, not that I know of. It would be a book and it's sequel in my opinion.  But maybe someone will chime in with some rarely used term.

 

[NoCat]

No idea. I just use duology.

 

[Bruce Blake]

Diptych just for fun?

 

[miss_fletcher]

Officially? Forthinthetrilogydividedbytwology.

*serious face*

I'd call book two a sequel.

 

[BrianKittrell]

I think Miss Fletcher is correct. Further, I think they don't keep a term for a two-part series because it's either one or two. One, two, three, four... is a series. One and two? Pair, couple, original + sequel, etc.

That being said, lots of people are using Duology and getting away with it. I bet it'll be a word in the dictionary in a few years.

But my personal favorite is doublet

 

[George Berger]

But my personal favorite is doublet

In jewelry, two pieces that go together in some fashion are occasionally referred to as a "duette".

 

[WHDean]

Don't know of a specific term, but if you follow the conventions for forming such words, the correctly formed neologism would be "diology" or "dyology," since "duo" is Latin, not Greek.

 

[bmcox]

I vote for diptych (though mostly used for art) and duette, both already mentioned here.

 

[Claudia King]

I imagine it'd be hard to find a word that'd convey the same meaning as "duology" to a broad audience. I like to go with what works, even if it isn't as pretty as you might want it to be.

 

[Cherise]

I like duo.

 

[Learnmegood]

A binary series?

 

[telracs]

two books is not a series.  so there isn't a word for it.  it's a book and its sequel.

 

[NathanWrann]

A set?

I agree. I think the term duology is becoming more accepted and that it will be in dictionaries within a few years.

I'd say if you want to use the term duology, feel free. Otherwise it's a novel and a sequel.

 

[Mainak Dhar]

Call 'em Book I and Book II and then sell them together as a Twofer....

 

[B. Justin Shier]

If you want take an old, lonely word and give it a new use...

bipartite
dimidiation
dikhotomos
furca
distich (my favorite)

Otherwise, WHDean is right, it should be diology, not duology.
