Arouse again (8)
I believe the answer is:
rekindle
'arouse again' is the definition.
('kindle' can be a synonym for 'arouse' so perhaps 'rekindle' is OK for 'arouse again')
This is the entire clue.
(Other definitions for rekindle that I've seen before include "Revive (something lost)" , "Light (a fire) again" , "Get the fire going again" , "Cause to start burning again" , "Cause to burn again" .)
