Delicacy (7)
I believe the answer is:
finesse
'delicacy' is the definition.
(I know that delicacy can be written as finesse)
This is the entire clue.
(Other definitions for finesse that I've seen before include "Delicate manipulation, perhaps in card game" , "subtle tactic" , "Artful management" , "Subtle skill; bridge ploy" , "Skilful elegance or expertise" .)
