I am in a Syntax class where we use the textbook Syntax: A Generative Introduction, 3rd Edition by Andrew Carnie.
There is a tree presented in the chapter on x-bar theory that indicates that the words "bright" and "dull" are adverbs and not adjectives. I am racking my brain trying to figure out if I am missing something or misunderstanding something or if it is just a mistake.
If it isn't a mistake, why are they presented as adverbs instead of adjectives?
Thank you!
