Australian banker courageous to keep pound (7)
I believe the answer is:
darling
'australian banker' is the definition.
The answer and definition can be both people as well as being singular nouns.
Maybe you can see an association between them that I can't see?
'courageous to keep pound' is the wordplay.
'courageous' becomes 'daring' (daring can mean adventurous or courageous).
'to keep' means one lot of letters goes inside another.
'pound' becomes 'L' (the pound sign is based on an L).
'daring' going around 'l' is 'DARLING'.
Can you help me to learn more?
(Other definitions for darling that I've seen before include "Pet" , "Adorable - honeybun" , "Wendy's family (Peter Pan)" , "Australian river and loved one" , "lover" .)
