- Refers to the culture of a group of three closely related Algonkian-speaking Indian tribes in Alberta and Montana, comprising the Pikuni, or Piegan, the Kainah, or Blood, and the Siksika, or Blackfoot proper (often referred to as the Northern Blackfoot). Not to be confused with the Sihasapa, another Plains Indian tribe that is also referred to as Blackfoot.
- Refers broadly to articles associated with or used in the context of a ceremony, which includes formal acts conducted elaborately, solemnly, and as prescribed by the ritual or protocol of religious, state, court, social, or tribal procedure.
- Typically reserved to refer narrowly to the cultures of the native peoples of the United States and Canada, excluding the Eskimos and Aleuts. For the indigenous peoples of Canada use the term "First Nations." For the broader concept of the cultures of any native peoples of Central America, South America, North America, or the West Indies who are considered to belong to the Mongoloid division of the human species, use "Amerindian (culture)."
- Indian peoples who inhabit, or formerly inhabited, the North American Great Plains, which is a vast grassland between the Mississippi River and the Rocky Mountains and from present-day provinces of Alberta and Saskatchewan in Canada through the present-day state of Texas in the United States. The area is drained principally by the Missouri and Mississippi rivers; the valleys of this watershed are the most reliable sites from which to obtain fresh water, wood, and most plant foods.
- Small or moderate size bags for carrying small articles, often having drawstrings, a flap, or closure hardware.
