Although thousands of people in Alberta and Montana speak Blackfoot, an Algonquian language, their numbers are diminishing and the survival of Blackfoot is in danger. Blackfoot Grammar, the companion volume to The Blackfoot Dictionary of Stems, Roots and Affixes Third Edition, provides description and analyses of the major features of Blackfoot grammar and language structures. The changes throughout this third edition reflect approaches refined through years of teaching experience. A new appendix, featuring a lengthy Blackfoot text with interlinear English translation has been added, as well as numerous corrections and additions to every chapter. This third edition of Blackfoot Grammar will be a welcome resource not only for those who wish to learn the language, but for all those with an interest in Native Studies and North American linguistics.
