Personality from France, the French revolutionary (4)
I believe the answer is:
self
'personality' is the definition.
(thesaurus)
'france the french revolutionary' is the wordplay.
'france' becomes 'f'.
'the french' becomes 'les' (les is the in french).
'revolutionary' says the letters should be written in reverse.
'f'+'les'='fles'
'fles' written backwards gives 'SELF'.
'from' acts as a link.
(Other definitions for self that I've seen before include "Will perhaps" , "Will the author" , "Ego, identity" , "Personality" , "Will the writer?" .)
