Settled anger in parody (6)
I believe the answer is:
satire
'parody' is the definition.
(thesaurus)
'settled anger' is the wordplay.
'settled' becomes 'sat' (I've seen this in other clues).
'anger' becomes 'ire' (synonyms).
'sat'+'ire'='SATIRE'
'in' is the link.
(Other definitions for satire that I've seen before include "Use of irony in writing" , "Sarcastic humour" , "Witty language used to convey insults or scorn" , "Irony or sarcasm in speech or writing" , "Jonathan Swift's forte?" .)
