Bank in which the greedy keep their money? (5)
I believe the answer is:
piggy
'bank' is the definition.
(piggy bank is a kind of bank)
'the greedy keep their money?' is the wordplay.
I cannot really understand how this works, but
'money?' could be 'p' and 'p' is found within the answer.
The remaining letters 'iggy' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
'in which' is the link.
Can you help me to learn more?
(Other definitions for piggy that I've seen before include "Greedy; little animal" , "Greedy; Muppet Miss" , "Porcine" , "Child's toe" .)
