Greetings-
I am drawing morphology trees and I am stuck.
I have to do one for the words, geekiness, conversational and retrovirus.
I am thinking the converstationally can be this way or just conversational-ly which would make it just adverb (highes branch/ top) then adjective extended branch...
My biggest issue, however is geekiness.
geeky which is the root word is a adjective, but the ness makes it a noun. Can a noun modify a adjective to make a new noun?

Yes, but ness is not a noun, it's simply another morpheme (and see below).
PLEAAAAAAASE HELP!!!!!!!!
