Subject of article written by myself (5)
I believe the answer is:
theme
'subject' is the definition.
(theme can mean a topic or subject)
'article written by myself' is the wordplay.
'article' becomes 'the' (the definite article in English).
'written by' is a charade indicator (letters next to each other).
'myself' becomes 'me'.
'the'+'me'='THEME'
'of' is the link.
(Other definitions for theme that I've seen before include "Short melody" , "Subject; recurring idea" , "He met (anag) - subject" , "Subject (of talk, text, etc)" , "Subject set for discussion" .)
