Endless woe for Scrooge? (5)
I believe the answer is:
miser
'for scrooge?' is the definition.
(Dickens' Ebenezer Scrooge is a miser)
'endless woe' is the wordplay.
'endless' means to remove the last letter.
'woe' becomes 'misery' (I've seen this before).
'misery' with its final letter removed is 'MISER'.
(Other definitions for miser that I've seen before include "Niggard" , "not a spendthrift" , "One hoarding wealth" , "Someone close" , "Niggardly person" .)
