Can be knocked out with a club (5)
I believe the answer is:
divot
'can' is the definition.
Although both the answer and definition are singular nouns, I cannot understand how they can define each other.
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for divot that I've seen before include "Clump taken by a golf swing" , "Turf lifted by golf club" , "Turf golfer dislodges" , "Piece of turf dug out by a golf club" , "Gouged-out turf" .)
