Finish, end (7)
I believe the answer is:
closure
I believe this is a double definition.
'finish' is the first definition.
(I've seen this in another clue)
'end' is the second definition.
(I know that closure is a type of end)
(Other definitions for closure that I've seen before include "Stoppage" , "sense of satisfaction" , "Resolution of emotional upheaval" , "end of debate" , "Sealing device" .)
