One uses a bow and arrow (6)
I believe the answer is:
archer
'one uses a bow and arrow' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for archer that I've seen before include "Small insect" , "stars" , "A bow-and-arrow man" , "One uses a bow and arrow" , "Bowman - ex-candidate for London Mayor" .)
