Greedy sort of bank in Paraguay hacked by current German government (5)
I believe the answer is:
piggy
'greedy' is the definition.
(I've seen this in another clue)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for piggy that I've seen before include "Porcine" , "Greedy; Muppet Miss" , "Child's toe" , "Greedy; little animal" .)
