This is a translation of a comparative grammar of five Algonquian Native American languages first published in Dutch in 1910. It has been expanded, corrected and improved in the form of translators notes based on much more recent and complete material. It also includes many bibliographical resources for most of the Algonquian language family, which are geared towards comparative language learning methods. The two most widely spoken languages of this group, Ojibway (frequently spelled Chippewa, Ojibwa or Ojibwe) and Cree, are both examples of the close knit Central Algonquian group, while Micmac and the extinct Natick belong to the Eastern group. The western Blackfoot is usually placed with the Plains Algonquian group, but it it is the most divergent member of the entire family and has roughly as many speakers as Micmac.
