Fighting may make rebel tingle (11)
I believe the answer is:
belligerent
'fighting' is the definition.
(synonyms)
'make rebel tingle' is the wordplay.
'make' indicates anagramming the letters.
'rebel'+'tingle'='rebeltingle'
'rebeltingle' is an anagram of 'BELLIGERENT'.
'may' acts as a link.
(Other definitions for belligerent that I've seen before include "hawk" , "fighting" , "Warlike" , "Hostile, aggressive" , "Aggressive - it'll be green (anag)" .)
