Robin Hood's skill (7)
I believe the answer is:
archery
'robin hood's skill' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for archery that I've seen before include "The sport of bowmen" , "Bow and arrow sport" , "The sport of shooting arrows with a bow" , "Shooting with bows and arrows" , "Sport of the bowman" .)
