Bring in, as money (4)
I believe the answer is:
earn
'bring in as money' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for earn that I've seen before include "Gain through labour or work" , "There's merit" , "Receive in return for" , "Gain credit from" , "Merit through work or effort" .)
