Eastern Abenaki is an extinct Algonquian language formerly spoken by the Abenaki people. They were spoken by several peoples, including the Penobscot of what is now Maine. The last known natively fluent speaker of Penobscot Abenaki, Madeline Shay, died in 1993. However, several Penobscot elders still speak Penobscot, and there is an ongoing effort to preserve it and teach it in the local schools; much of the language was preserved by Frank Siebert. Other speakers of Eastern Abenaki included tribes such as the Amoscocongon who spoke the Arosagunticook dialect, and the Caniba, which are documented in French-language materials from the colonial period.
