Sack female with temper (4)
I believe the answer is:
fire
'sack' is the definition.
('fire' can be a synonym of 'sack')
'female with temper' is the wordplay.
'female' becomes 'f' (abbreviation).
'with' means one lot of letters go next to another.
'temper' becomes 'ire' (I've seen this before).
'f'+'ire'='FIRE'
(Other definitions for fire that I've seen before include "Let off" , "cut" , "See 5" , "Flame - dismiss - shoot" , "Set light to; shoot" .)
