Profits from a comeback? (6)
I believe the answer is:
return
This clue is a double definition.
'profits' is the first definition.
(thesaurus)
'a comeback?' is the second definition.
(I know that comeback can be written as return)
'from' acts as a link.
(Other definitions for return that I've seen before include "Homecoming" , "Come back with a formal report on transactions" , "Yield" , "Come back with financial statement" , "'Come, go or bring back (6)'" .)
