This question closely ties into a question I had about verbless clauses. However, I am writing a new one at the suggestion of a user.
Polarity-sensitive aspectual-related words are those such as 'still' and 'already.' I have established that modifiers like 'obviously,' which I believe to be evaluative in nature, can function as modifiers in an adjective phrase, as determined by the answer to my question linked above, where I confused them to be part of verbless clauses. But can 'still' and 'already' also be modifiers in an adjective phrase?
Below is an example similar to the one from my previous question, using 'still' instead of 'obviously.' I have highlighted in bold what I believe to be the complete adjective phrase.
He was crying, still sad because of the passing of his father.
