Nominal skill (3)
I believe the answer is:
art
'skill' is the definition.
(both can mean a talent)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for art that I've seen before include "are old-fashioned" , "For example, Blakey's creative" , "Paintings etc." , "Painting, for instance" , "Works of beauty created by humans" .)
