Gain point when catching or if fumbling (6)
I believe the answer is:
profit
'gain' is the definition.
(I know that gain can be written as profit)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for profit that I've seen before include "Use" , "Net gain after expenses" , "Money made" , "returns" , "Surplus earnings" .)
