Auregnais was the Norman dialect of the Channel Island of Alderney. It was related to the Guernésiais, Jèrriais and Sercquiais dialects of the neighbouring islands, but most closely related to Continental Norman. Following the death of the last known native speaker of Auregnais in 1960, the dialect became extinct. Only a few examples of Auregnais survive, mostly in place names in Alderney. Though a small amount of written literature, in the form of poems and prose, remains. One audio recording is known to exist and there are rememberers. According to linguists, the disappearance of Auregnais is the worst documented case of recent language extinction.
