Evened out the French area (6)
I believe the answer is:
vendee
'evened out the french area' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for vendee that I've seen before include "Coastal department of western France" , "Evened out the area in France on the Atlantic" , "Evened out the French area" , "Region in west central France, home to Challons" , "Buyer; area of Western FRance" .)
