ブラックフット族の公用語はなんですか？
The Blackfoot language, also called Siksiká (ᓱᖽᐧᖿ, its denomination in ISO 639-3), (; ], ), often anglicised as , is an Algonquian language spoken by the Blackfoot or "Niitsitapi" people, who currently live in the northwestern plains of North America. There are four dialects, three of which are spoken in Alberta, Canada, and one of which is spoken in the United States: "Siksiká" (Blackfoot), to the southeast of Calgary, Alberta; "Kainai" (Blood, Many Chiefs), spoken in Alberta between Cardston and Lethbridge; "Aapátohsipikani" (Northern Piegan), to the west of Fort MacLeod; and "Aamsskáápipikani" (Southern Piegan), in northwestern Montana. The name Blackfoot probably comes from the blackened soles of the leather shoes that the people wore.
