Article is becoming true-to-life (9)
I believe the answer is:
realistic
'true-to-life' is the definition.
('realistic' can be similar in meaning to 'true-to-life')
'article is becoming' is the wordplay.
'becoming' indicates anagramming the letters.
'article'+'is'='articleis'
'articleis' is an anagram of 'REALISTIC'.
(Other definitions for realistic that I've seen before include "Pragmatic" , "Practicable" , "Lifelike" , "Facing facts, as it is clear" , "Objective" .)
