In the phrase "man enough", is man an adjective?

Question

I do realize that the phrase *"to be man enough"* is an idiom. But I wonder what is the grammatical/syntactic role that *man* plays in it. Is it an uncountable noun? An adjective? An adverb? Or perhaps because the phrase is an idiom, the question makes no sense?

Answer 1

man enough is an adjectival phrase.
