Graceful skill (7)
I believe the answer is:
finesse
'graceful skill' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for finesse that I've seen before include "Delicate manipulation, perhaps in card game" , "Skilful elegance or expertise" , "Achieve with subtlety and skill" , "Subtle skill; bridge ploy" , "Artifice" .)
