Skill or knack (3)
I believe the answer is:
art
I believe this clue is a double definition.
'skill' is the first definition.
(both can mean a talent)
'knack' is the second definition.
(both can mean a skill or talent)
(Other definitions for art that I've seen before include "-- Garfunkel, singer" , "are old-fashioned" , "This gallery displays paintings" , "Skill, craft" , "Lovely piece of work" .)
