Fighter’s aura is stirring, gripping male (7)
I believe the answer is:
samurai
'fighter's' is the definition.
(samurai is a type of warrior or fighter)
'aura is stirring gripping male' is the wordplay.
'stirring' indicates anagramming the letters.
'gripping' is an insertion indicator (inserted letters are gripped).
'male' becomes 'm' (common abbreviation).
'aura'+'is'='aurais'
'aurais' is an anagram of 'saurai'.
'saurai' enclosing 'm' is 'SAMURAI'.
(Other definitions for samurai that I've seen before include "Japanese militarist" , "Jap. warrior caste" , "Member of Japanese warrior caste" , "Traditional Japanese warriors" , "Former Japanese military caste member" .)
