KUT meaning in Regional ?

The Kutenai ( KOOT-ən-AY, -⁠EE), also known as the Ktunaxa ( tun-AH-hah; Kutenai: [ktunʌ́χɑ̝]), Ksanka ( k-SAHN-kah), Kootenay (in Canada) and Kootenai (in the United States), are an indigenous people of Canada and the United States. Kutenai bands live in southeastern British Columbia, northern Idaho, and western Montana. The Kutenai language is a language isolate, thus unrelated to the languages of neighboring peoples or any other known language.

Four bands form the Ktunaxa Nation in British Columbia. The Ktunaxa Nation was historically closely associated with the Shuswap Indian Band through tribal association and intermarriage. Two federally recognized tribes represent Kutenai people in the U.S.: the Kootenai Tribe of Idaho and the Confederated Salish and Kootenai Tribes in Montana, a confederation also including Bitterroot Salish and Pend d'Oreilles bands.
