Succeeded in copying one (3)
I believe the answer is:
won
'succeeded' is the definition.
(I've seen this in another clue)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for won that I've seen before include "Succeeded, conquered" , "Came first" , "Gained a victory" , "Triumphed" , "prevailed" .)
