French dramatist has extra setting for story (7)
I believe the answer is:
moliere
'french dramatist' is the definition.
(I've seen this before)
'extra setting for story' is the wordplay.
'extra' becomes 'more' (both can mean additional).
'setting for' is an insertion indicator.
'story' becomes 'lie' (story can mean a fabrication).
'more' placed around 'lie' is 'MOLIERE'.
'has' is the link.
(Other definitions for moliere that I've seen before include "French dramatist" , "17th century French playwright" , "Fr. comic dramatist" , "Fr. dramatist (Tartuffe)" , "French writer" .)
