Tahltan language

Tahltan, Tāłtān, also called Tałtan ẕāke ("Tahltan people language"), dah dẕāhge ("our language") or didene keh ("this people’s way") is a poorly documented Northern Athabaskan language historically spoken by the Tahltan people (also "Nahanni") who live in northern British Columbia around Telegraph Creek, Dease Lake, and Iskut. Tahltan is a critically endangered language. Several linguists classify Tahltan as a dialect of the same language as Tagish and Kaska (Krauss and Golla 1981, Mithun 1999).

Language revitalization
As of May 2013, language researcher Dr. Judy Thompson estimated that there are 30 Tahltan speakers. A new Language and Culture office is exploring evening "language immersion" classes, a Master-Apprentice program, and creating a "language nest" for teaching the language to young children. Scholarships are planned for part-time language learners.

Lacking written documentation, it was unclear to the language revitalization coordinator how to teach the language, and how to explain the grammar. "After a year of study, Oscar Dennis says he, along with Reginald and Ryan Dennis, have finally cracked the code on Tahltan language’s fundamental patterns." As a Dene language, like Navajo, Tahltan has “encoded” patterns in which small pieces are added to words to create meaning. "Dr. Gregory Anderson from the Living Tongues Institute visited our territory, and was so impressed with the team’s work that he said he 'couldn’t improve upon it.'"

A digital archive of Tahltan recordings, located "at the Tahltan Language Revitalization Offices in Dease Lake, Iskut and Telegraph Creek" can be used on iPods.
