 Abstract:
 "argues that the Celtic substratum in the development of the French language has been underestimated. He compares Atlas Linguistique de la France (ALF) maps with Breton ones, using the data recorded in Le Roux's Atlas Linguistique de la Basse-Bretagne and Le Dû's Nouvel Atlas Linguistique de la Basse-Bretagne, demonstrating that several of these maps reveal the presence of ALF data whose origin is clearly Celtic."
