French playwright to a greater extent describes story (7)
I believe the answer is:
moliere
'french playwright' is the definition.
(I've seen this in another clue)
'to a greater extent describes story' is the wordplay.
'to a greater extent' becomes 'more' (synonyms).
'describes' is an insertion indicator (describe can mean to form the outline of).
'story' becomes 'lie' (story can mean a fabrication).
'more' placed around 'lie' is 'MOLIERE'.
(Other definitions for moliere that I've seen before include "French playwright (Tartuffe)" , "C17 French playwright (Le Misanthrope)" , "Fr. comic dramatist" , "Fr. dramatist (Tartuffe)" , "French dramatist" .)
