Excite female anger (4)
I believe the answer is:
fire
'excite' is the definition.
(I know this)
'female anger' is the wordplay.
'female' becomes 'f' (abbreviation).
'anger' becomes 'ire' (ire is intense rage).
'f'+'ire'='FIRE'
(Other definitions for fire that I've seen before include "Set light to; shoot" , "Let off" , "Blaze - sack" , "Blaze - discharge" , "cut" .)
