Article on me is the subject (5)
I believe the answer is:
theme
'the subject' is the definition.
(theme can mean a topic or subject)
'article on me' is the wordplay.
'article' becomes 'the' (the definite article in English).
'on' says to put letters next to each other.
'the'+'me'='THEME'
'is' acts as a link.
(Other definitions for theme that I've seen before include "He met (anag) - subject" , "Musical motif" , "idea of the work" , "The main sound" , "Motif or melody" .)
