A Syrian perhaps is crazy to reject a fight (9)
I believe the answer is:
damascene
'a syrian' is the definition.
(Damascene is an example)
'is crazy to reject a fight' is the wordplay.
'is crazy' becomes 'mad' (synonyms).
'to reject' says the letters should be written backwards.
'fight' becomes 'scene' (I can't justify this - if you can you should give a lot more credence to this answer).
'mad' backwards is 'dam'.
'dam'+'a'+'scene'='DAMASCENE'
'perhaps' acts as a link.
Can you help me to learn more?
(Other definitions for damascene that I've seen before include "steely ornamentation" , "as conversion is described" , "ornament" , "in Arab city" , "Syrian" .)
