Miser hauling a bit of gold away on retirement (7)
I believe the answer is:
niggard
'miser' is the definition.
(synonyms)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for niggard that I've seen before include "Drag gin around for the miser" , "Stingy type" , "He's tight" , "Mean, stingy person" , "Skinflint" .)
