Survive terrible evil (4)
I believe the answer is:
live
'survive' is the definition.
(I know that survive can be written as live)
'terrible evil' is the wordplay.
'terrible' indicates anagramming the letters.
'evil' anagrammed gives 'LIVE'.
(Other definitions for live that I've seen before include "Electrically charged" , "Reside; given in concert" , "A . . . . wire is a highly energetic person" , "Present in person, not recorded" , "shocking potentially?" .)
