Conclusion, finale (3)
I believe the answer is:
end
I believe this clue is a double definition.
'conclusion' is the first definition.
(something's conclusion is its end)
'finale' is the second definition.
(I've seen this in another clue)
(Other definitions for end that I've seen before include "Discontinue" , "Complete" , "Novel by Graham Greene" , "Culmination" , "Aim - point - finish" .)
