Fight to make robbery profitable? (5)
I believe the answer is:
fence
'fight' is the definition.
(fencing is a sword-fighting sport)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for fence that I've seen before include "Bound over this" , "Wooden or wire barrier" , "crook" , "Stolen goods dealer" , "Beat about the bush" .)
