Outcome, upshot (6)
I believe the answer is:
result
I believe this is a double definition.
'outcome' is the first definition.
(I know that outcome can be written as result)
'upshot' is the second definition.
(I know that upshot can be written as result)
(Other definitions for result that I've seen before include "End - issue" , "Effect of lustre" , "Rustle (anag.)" , "Outcome of an undertaking" , "'Outcome, upshot (6)'" .)
