Finance expert curtailing indulgence? More likely (9)
I believe the answer is:
treasurer
'finance expert' is the definition.
(I've seen this before)
'curtailing indulgence? more likely' is the wordplay.
I cannot quite understand how this works, but
'more likely' could be 'surer' (I've seen this in another clue) and 'surer' is located 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 treasurer that I've seen before include "Official in charge of funds" , "Official in charge of finances" , "Manager of funds" , "Club official" , "Finance expert" .)
