Scrooges (6)
I believe the answer is:
misers
'scrooges' is the definition.
('miser' can be a synonym of 'scrooge')
This is all the clue.
(Other definitions for misers that I've seen before include "Persons with short arms and deep pockets" , "Skinflints" , "They're stingy hoarders" , "They hoard money" , "Mean people like Scrooge" .)
