Rake in money coming back that expert divides (9)
I believe the answer is:
reprobate
'rake in money' is the definition.
'reprobate' can be an answer for 'rake' (I've seen this before). I am not sure about the 'in money' bit.
'coming back that expert divides' is the wordplay.
'coming back' becomes 'rebate' (I am not sure about this - if you are sure you should believe this answer much more).
'that expert' becomes 'pro' (I've seen this before).
'divides' means one lot of letters goes inside another (inserted letters create a division or opening).
'rebate' placed around 'pro' is 'REPROBATE'.
Can you help me to learn more?
(Other definitions for reprobate that I've seen before include "Sinner" , "Disapprove of" , "Ne'er-do-well" , "Person without moral scruples" , "immoral" .)
