Ploughs back the profits? (7)
I believe the answer is:
returns
'the profits?' is the definition.
(I've seen this before)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for returns that I've seen before include "Throws made by cricketers" , "profit" , "Profits" , "proceeds" , "Goods sent back" .)
