Creative knack (3)
I believe the answer is:
art
'creative knack' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for art that I've seen before include "Work such as painting or sculpture" , "-- Garfunkel, singer" , "Eg, paintings, sculpture" , "are old-fashioned" , "Skill, knack" .)
