Native of Brittany (6)
I believe the answer is:
breton
'native of brittany' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for breton that I've seen before include "Cooked with cheese and/or breadcrumbs on top" , "Inhabitant of northwest France" , "from Northern France" , "One from Brest" , "French Celtic language" .)
