Where the golfer puts his coal? (6)
I believe the answer is:
bunker
'coal?' is the definition.
(thesaurus)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for bunker that I've seen before include "Underground shelter, store" , "Golf hazard and fuel storage container" , "Sandy hazard on golf course" , "Wartime shelter" , "Storage container for coal" .)
