Endless grief for Scrooge, perhaps (5)
I believe the answer is:
miser
'for scrooge perhaps' is the definition.
(Dickens' Ebenezer Scrooge is a miser)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for miser that I've seen before include "we may find boring" , "Stingy person like Scrooge" , "Stingy type" , "Curmudgeon" , "Tight-fisted person" .)
