Chatter about Dicky's outcome (3-3)
I believe the answer is:
pay-off
'outcome' is the definition.
(I have seen 'Final outcome ' mean 'pay off' so perhaps 'outcome' could also mean 'pay off')
'chatter about dicky's' is the wordplay.
'chatter' becomes 'yap' (I've seen this in another clue).
'about' shows that the letters should be reversed in order.
'dicky' becomes 'off'.
'yap' backwards is 'pay'.
'pay'+'off'='PAY-OFF'
(Other definitions for pay-off that I've seen before include "Result" , "Return on an investment" , "Final settlement - backhander" , "Deserved reward" .)
