Proposal by the writer to follow Southern revolutionary (6)
I believe the answer is:
scheme
'proposal' is the definition.
(thesaurus)
'the writer to follow southern revolutionary' is the wordplay.
'the writer' becomes 'me' (the person who is writing these clues).
'to follow' is a charade indicator (letters next to each other).
'southern' becomes 's' (abbreviation).
'revolutionary' becomes 'che' (Che Guevara the Marxist revolutionary).
's'+'che'='sche'
'me' put after 'sche' is 'SCHEME'.
'by' acts as a link.
(Other definitions for scheme that I've seen before include "Conive, intrigue" , "Program" , "Elaborate and systematic plan of action" , "Secret plan, plot" , "Lay plans" .)
