Not very good at needing money (4)
I believe the answer is:
poor
This clue might be a double definition.
'not very good' is the first definition.
Both the answer and definition are adjectives. Maybe you can see a link between them that I don't see?
'needing money' is the second definition.
'at' is the link.
Can you help me to learn more?
(Other definitions for poor that I've seen before include "hopeless" , "deserving of pity" , "Rotten" , "'It's a . . . . heart that never rejoices'" , "Impecunious; wretched" .)
