What's left at bank brings stability (7)
I believe the answer is:
balance
'stability' is the definition.
(I've seen this before)
'what's left at bank' is the wordplay.
I cannot really understand how this works, but
'left' could be 'al' (I've seen this in other clues) and 'al' is located in the answer.
This may be the basis of clue (or it may be nonsense).
'brings' is the link.
Can you help me to learn more?
(Other definitions for balance that I've seen before include "Scale for weighing" , "Rest" , "Libra - amount in account" , "Sign" , "Equilibrium or symmetry" .)
