Borrowed from Medieval Latin Delphīnātus (literally “the Dauphinate”), ellipsis of Delphīnātus Viennēnsis (“the Dauphinate of Vienne”, literally “the Viennese Dauphinate”). The Latin delphīnātus (“dauphinate”) derives from delphīnus (“dauphin”) + -ātus (suffix forming abstract nouns). Doublet of dauphinate, Dauphiny, and Dauphiné.
