Resolution almost lost in course of recovery (7)
I believe the answer is:
closure
'resolution' is the definition.
(I have seen 'Emotional resolution ' mean 'closure' so perhaps 'resolution' could also mean 'closure')
'almost lost in course of recovery' is the wordplay.
'almost' means to remove the last letter (most of the word but not all of it).
'in' is an insertion indicator.
'course of recovery' becomes 'cure' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'lost' with its final letter taken away is 'los'.
'los' put within 'cure' is 'CLOSURE'.
Can you help me to learn more?
(Other definitions for closure that I've seen before include "End; fastening" , "End or act of shutting" , "Ending" , "Sealing device" , "Final shutdown" .)
