End or conclusion (7)
I believe the answer is:
closure
I believe this is a double definition.
'end' is the first definition.
(I know that closure is a more specific form of the action end)
'conclusion' is the second definition.
(I know that closure is a type of conclusion)
(Other definitions for closure that I've seen before include "Feeling of emotional resolution" , "End; fastening" , "Settlement giving psychological satisfaction" , "Lose cur (anag.)" , "Ending" .)
