Article is worked on (9)
I believe the answer is:
realistic
'on' is the definition.
Both the definition and answer are adjectives. Maybe there's an association between them I don't understand?
'article is worked' is the wordplay.
'worked' indicates anagramming the letters.
'article'+'is'='articleis'
'articleis' is an anagram of 'REALISTIC'.
Can you help me to learn more?
(Other definitions for realistic that I've seen before include "Practicable" , "Pragmatic" , "accurate picture" , "Faithful" , "Down-to-earth" .)
