A match for Satan? (7)
I believe the answer is:
lucifer
I believe this is a double definition.
'a match' is the first definition.
(I know that match can be written as lucifer)
'for satan?' is the second definition.
('Lucifer' can be a synonym of 'satan')
(Other definitions for lucifer that I've seen before include "Rising star" , "Light" , "the adversary" , "Satan, the Dark Angel" , "Evil spirit" .)
