iii) He died young. They served the coffee blindfolded.
iv) Furious, he stormed out of the room.
The AdjPs in [iii-iv] function as predicative adjunct. Those in [iii] are integrated into clause structure and hence modifiers, while that in [iv] is detached and hence a supplement. All adjectives that can function as predicative adjunct can also function as predicative complement.
CGEL says the predicative adjuncts in [iii], young and blindfolded, are modifiers. Which of the next modification does the book mean?
“The words used to modify nouns are typically adjectives, and the words that similarly modify verbs are adverbs.” (CGEL, p.526)
I wonder whether the modifiers in [iii] function as both predicative that depict the subjects and modify them; or even thought they describe subjects, they are integrated into the structure by modifying the verbs.
