Female anger is employed in display of temper (9)
I believe the answer is:
fireworks
'in display of temper' is the definition.
I can't judge whether this defines the answer.
'female anger is employed' is the wordplay.
'female' becomes 'f' (abbreviation).
'anger' becomes 'ire' (ire is intense rage).
'is employed' becomes 'works' (I've seen this in another clue).
'f'+'ire'+'works'='FIREWORKS'
Can you help me to learn more?
(Other definitions for fireworks that I've seen before include "rockets, perhaps" , "Pyrotechnics" , "Display on November 5th etc" .)
