Angered lover, we hear, displaying weapon (8)
I believe the answer is:
crossbow
'weapon' is the definition.
(crossbow is a kind of weapon)
'angered lover we hear' is the wordplay.
'angered' becomes 'cross' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'lover' becomes 'beau' (beau is a kind of lover).
'we hear' indicates a 'sounds like' (homophone) clue.
'beau' is a homophone of 'bow'.
'cross'+'bow'='CROSSBOW'
'displaying' acts as a link.
Can you help me to learn more?
(Other definitions for crossbow that I've seen before include "Weapon (used to set off a quarrel?)" , "Weapon for shooting bolts" , "it could be wounding" , "Old weapon of war" , "Old weapon wiht mechanism for firing bolt" .)
