Recovers from series of strokes (7)
I believe the answer is:
rallies
I believe this clue is a double definition.
'recovers' is the first definition.
(rallying is a kind of recovering)
'series of strokes' is the second definition.
(I've seen this before)
'from' acts as a link.
(Other definitions for rallies that I've seen before include "Car races on public roads" , "Recovers in health" , "Recovers strength for mass gatherings" , "Extended exchanges of tennis strokes" , "Gets better" .)
