Adjective phrase - Wikipedia
https://en.wikipedia.org/wiki/Adjective_phraseThere is a tendency to call a phrase an adjectival phrase when that phrase is functioning like an adjective phrase, but is not actually headed by an adjective. For example, in Mr Clinton is a man of wealth, the prepositional phrase of wealth modifies a man in a manner similar to how an adjective phrase would, and it can be reworded with an adjective, e.g. Mr Clinton is a wealthy man. A more accurate term for such cases is phrasal attributive or attributive phrase.
