Much fury, some soreness, absolute uproar (6)
I believe the answer is:
furore
'uproar' is the definition.
(synonyms)
'much fury some soreness absolute' is the wordplay.
'much' means to remove the last letter (much but not all of the word).
'some soreness absolute' becomes 'ore' (I can't explain this - if you can you should believe this answer much more).
'fury' with its final letter taken away is 'fur'.
'fur'+'ore'='FURORE'
Can you help me to learn more?
(Other definitions for furore that I've seen before include "An uproar, of admiration or anger" , "Uproar of fury or general noise" , "Turmoil, uproar" , "Disturbance" , "An uproar, outbreak of fury" .)
