Conflict mediator finally intervening between two parties? (11)
I believe the answer is:
discordance
'conflict' is the definition.
(discordance is a kind of conflict)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for discordance that I've seen before include "Harsh noise" , "Conflict; lack of harmony" , "Argy-bargy" .)
