is there a word akin to triliogy in this format ?

sequel would definatley suffice. Is there a partic one thats for two?

Message withdrawn

was thinking about the term 'two'

as trilogy is three
xxxxxx is two.

duo;ogy

do i win ????

dunno but have just found out that a tetralogy is 4

duology or dilogy

A pair?

I think it's duology

but that doesn't get used much

#2 would be a sequel

dilogy sounds good

as does duology

thank you
