True information I included in French article (7)
I believe the answer is:
genuine
'true' is the definition.
(I know that true can be written as genuine)
'information i included in french article' is the wordplay.
'information' becomes 'gen' (gen can informally mean information).
'included in' is an insertion indicator.
'french article' becomes 'une' (indefinite article in French).
'i' put within 'une' is 'uine'.
'gen'+'uine'='GENUINE'
(Other definitions for genuine that I've seen before include "Native" , "Ingenue - the real McCoy" , "Real, true" , "Not fake or counterfeit" , "Real; sincere" .)
