No sides can put up with such discord (10)
I believe the answer is:
dissonance
'discord' is the definition.
(thesaurus)
'no sides can put up with' is the wordplay.
'no sides can' anagrams to 'DISSONANCE'.
However, I'm unsure how the anagram is indicated.
'such' is the link.
Can you help me to learn more?
(Other definitions for dissonance that I've seen before include "quartet?" , "Clashing quality of musical notes" , "Discordance" , "Lack of harmony" , "sounds harsh" .)
