adjective is usedIt is true that when the adjective is used in attributive position there is no syntactic or morphological difference to reflect the two possibilities.
adjective and nounTo answer the initial question first, it is certainly true that for ascriptive adjectives at least, with adjective and noun held constant, alternation between qualification and assignment can produce no difference in either the entity identified or the pattern of assignment of properties.
