Îethka Nakoda Language in Nakoda Country is the first language instruction book within the Durvile Spirit of Nature series. It features the Îethka First Nation language in context and in action. The book contains a collection of stories by Îethka authors, with each story culminating in a learning section. To assist in nuances of the language, the book also includes an orthography, a glossary, and audio components as web links. A beautifully produced audiobook, with authors' voices and bonus features is also available to link with at Durvile.com. The Îethka Nakoda People are an integral part of the Treaty 7 group of Indigenous Nations in Southern Alberta and their spoken language is part of the Dakota linguistic group.
