Adroitness (7)
I believe the answer is:
finesse
'adroitness' 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 "Subtlety of contrivance in cards" , "Adroitness" , "Subtly skilful handling of a situation" , "Subtlety, expertise" , "Delicate handling of a situation" .)
