Cryptic clue fair? Without a match! (7)
I believe the answer is:
lucifer
'match' is the definition.
('lucifer' can be a synonym of 'match')
'cryptic clue fair? without a' is the wordplay.
'cryptic' indicates an anagram (I've seen this in other clues).
'without' suggests deleting specific letters.
'clue'+'fair'='cluefair'
'cluefair' with 'a' taken out is 'cluefir'.
'cluefir' is an anagram of 'LUCIFER'.
(Other definitions for lucifer that I've seen before include "Devil - match!" , "once a match for > Dickens" , "Evil spirit" , "the adversary" , "Devilish sort of match" .)
