An adjectival quality often characterizes a subject more stably than a finite event does. For this reason, the semantic status of qualitative derivatives raises an issue: does a particular use transfer a class-like nominal meaning, or does it carry its transferred quality through the derivative's relation to its bearer?
The commentary discusses this tension. One treatment emphasizes the relative independence of the quality; another insists on the dependent character of derived predication.
The label cannot be decided by external word-shape alone. One must understand what the expression means and how its formation is being analyzed.
