Golfers' cards? (5)
I believe the answer is:
clubs
'cards?' is the definition.
(club is a kind of card)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for clubs that I've seen before include "black suit" , "cabarets" , "discos" , "For game, you may need five" , "Orders" .)
