Slur I’d retracted well before fury (9)
I believe the answer is:
disparage
'slur' is the definition.
(thesaurus)
'i'd retracted well before fury' is the wordplay.
'retracted' says the letters should be written backwards.
'well' becomes 'spa' (I've seen this before**).
'before' says to put letters next to each other.
'fury' becomes 'rage' ('rage' can be a synonym of 'fury').
'id' in reverse letter order is 'di'.
'di'+'spa'+'rage'='DISPARAGE'
(Other definitions for disparage that I've seen before include "Belittled" , "I grasped a change to belittle" , "Run down" , "Slight" , "Scorn" .)
