Recovered, effectively (4)
I believe the answer is:
well
I believe this is a double definition.
'recovered' is the first definition.
(similar in meaning)
'effectively' is the second definition.
(thesaurus)
(Other definitions for well that I've seen before include "Profoundly" , "Bore; very much" , "Issue forth" , "abundantly" , "Fit and healthy" .)
