Aussie banker in love (7)
I believe the answer is:
darling
'love' is the definition.
(both are terms of endearment)
'aussie banker in' is the wordplay.
I cannot really understand how this works, but
'in' is present in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for darling that I've seen before include "Favourite" , "Victorian heroine" , "Film with Julie Christie and Dirk Bogarde - sweetheart" , "Beloved" , "lover" .)
