Represented our scorn about article, becoming spiteful (9)
I believe the answer is:
rancorous
'spiteful' is the definition.
(thesaurus)
'represented our scorn about article' is the wordplay.
'represented' indicates an anagram.
'about' indicates putting letters inside.
'article' becomes 'a' (indefinite article).
'our'+'scorn'='ourscorn'
'ourscorn' is an anagram of 'rncorous'.
'rncorous' enclosing 'a' is 'RANCOROUS'.
'becoming' acts as a link.
(Other definitions for rancorous that I've seen before include "spiteful?" , "Showing bitter resentment" , "Acrimonious" , "Resentful, bitter" .)
