Start to recover from exchange of shots (5)
I believe the answer is:
rally
I believe this is a triple definition!
'start to recover' is the first definition.
'from' is a link.
'exchange' is the second definition.
(rally is a kind of exchange)
'of' is a link.
'shots' is the third definition.
(I have seen 'several shots' mean 'rally' so perhaps 'shots' could also mean 'rally')
(Other definitions for rally that I've seen before include "Recover health" , "Bring together for a purpose, troops perhaps" , "Muster" , "Mass meeting; car race" , "Recover strength after illness" .)
