Central idea in article by today's compiler (5)
I believe the answer is:
theme
This might be a double definition.
'central idea' is the first definition.
(I've seen this in another clue)
'article by today's compiler' is the second definition.
'theme' can be an answer for 'article' (thesaurus). I am not sure about the 'by today's compiler' bit.
'in' acts as a link.
Can you help me to learn more?
(Other definitions for theme that I've seen before include "Short melody" , "Thread, melody" , "essay" , "Signature tune" , "matter for discussion" .)
