Difficulty for golfer, say, without hole finally completed (7)
I believe the answer is:
through
'completed' is the definition.
(I've seen this in another clue)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for through that I've seen before include "Using" , "From one end or side to the other" , "made it to the next stage" , "clear" , "From beginning to end" .)
