Defeat inspiring anger with defence (8)
I believe the answer is:
firewall
'defence' is the definition.
I don't know anything about this answer so I can't judge whether it can be defined by this definition.
'defeat inspiring anger with' is the wordplay.
'defeat' becomes 'fall' (fall can mean a loss or defeat).
'inspiring' is an insertion indicator.
'anger' becomes 'ire' (ire is intense rage).
'with' becomes 'w' (abbreviation).
'ire'+'w'='irew'
'fall' placed around 'irew' is 'FIREWALL'.
Can you help me to learn more?
(Other definitions for firewall that I've seen before include "A protective system" , "Software protection for computer" , "network protection" , "Computer security system against online attack" .)
