A language dies when you don't have children learning it at home

"A language dies when you don't have children picking it up in the home," says Scott DeLancey, a University of Oregon linguist.

Here in America's Northwest, there are signs policymakers are beginning to take some notice. Last May, the Oregon State Legislature passed a resolution honoring Ms. Johnson's grandmother, Gladys Thompson, for her efforts to teach Kiksht and "her dedication to the preservation of Indian ways."

In 2006, the National Science Foundation awarded $5 million to support efforts to digitally record more than 60 endangered languages around the world. Included was $263,000 to document stories and conversations in Tlingit, Haida, and Tsimshian, spoken along the Alexander Archipelago in Alaska and islands off British Columbia.

"At least it's a validation of the implications of what is to be lost," says Patricia Shaw, director of the First Nations Languages Program in Vancouver, British Columbia.

The Great Sioux Nation

The Great Sioux Nation is actually made up of 18 separate tribes, or bands in the US, and 12 in Canada. These are divided into three divisions: the Lakota Sioux, Dakota Sioux, and the Nakota Sioux.



Each division speaks a different, but similar, Sioux language dialect.



The individual Sioux Tribes are scattered across several reservations and communities in North and South Dakota, Minnesota, Nebraska, and also in Manitoba and southern Saskatchewan in Canada.

The Yankton-Yanktonai, the smallest division, reside on the Yankton reservation in South Dakota and the Northern portion of Standing Rock Reservation, while the Santee live mostly in Minnesota and Nebraska, but include bands in the Sisseton-Wahpeton, Flandreau, and Crow Creek Reservations in South Dakota. The Lakota are the westernmost of the three groups, occupying lands in both North and South Dakota.

The Yankton-Yanktonai are a branch of Sioux peoples who moved into northern Minnesota. They originally constituted of two main ethnic groups: the Yankton ("campers at the end") and Yanktonai ("lesser campers at the end"). Economically, they were involved in quarrying pipestone.
