This subfamily of around 30 languages is divided into three groups according to geography: Plains, Central, and Eastern Algonquian; of these three, only Eastern Algonquian constitutes a true genetic subgroup. The languages are listed below, following the classifications of Goddard and Mithun. Extinct languages are marked with †, and endangered languages are noted as such. For dialects and subdialects, consult the separate main articles for each of the three divisions.
Subgroups
Eastern Algonquian is a true genetic subgrouping. The Plains Algonquian and the Central Algonquian groups are not genetic groupings but rather areal groupings. However, these areal groups often do share linguistic features, but the sharing is attributed to language contact. Paul Proulx has argued that this traditional view is incorrect, and that Central Algonquian is a genetic subgroup, with Eastern Algonquian consisting of several different subgroups. However, this classification scheme has failed to gain acceptance from other specialists in the Algonquian languages. Instead, the commonly accepted subgrouping scheme is that proposed by Ives Goddard. The essence of this proposal is that Proto-Algonquian originated with people to the west, perhaps in the Plateau region of Idaho and Oregon or the Rocky Mountain-Great Plains boundary of Montana, and then moved east, dropping off subgroups as people migrated. By this scenario, Blackfoot was the first language to branch off, which coincides well with its being the most divergent language of Algonquian. In west-to-east order, the subsequent branchings were:
Arapaho-Gros Ventre, Cree-Montagnais, Menominee, and Cheyenne;
This historical reconstruction accords best with the observed levels of divergence within the family, whereby the most divergent languages are found furthest west, and the shallowest subgroupings are found furthest to the east. Goddard also points out that there is clear evidence for pre-historical contact between Eastern Algonquian and Cree-Montagnais, as well as between Cheyenne and Arapaho-Gros Ventre. There has long been especially extensive back-and-forth influence between Cree and Ojibwe. It has been suggested that the "Eastern Great Lakes" languages – what Goddard has called "Core Central", e.g., Ojibwe–Potawatomi, Shawnee, Sauk–Fox–Kickapoo, and Miami-Illinois – may also constitute their own genetic grouping within Algonquian. They share certain intriguing lexical and phonological innovations. However, this theory has not yet been fully fleshed out and is still considered conjectural. Algonquian is sometimes said to have included the extinct Beothuk language of Newfoundland, whose speakers were both in geographic proximity to Algonquian speakers and who share DNA in common with the Algonquian-speaking Miꞌkmaq. However, linguistic evidence is scarce and poorly recorded, and it is unlikely that reliable evidence of a connection can be found.
Grammatical features
The Algonquian language family is known for its complex polysyntheticmorphology and sophisticated verb system. Statements that take many words to say in English can be expressed with a single word. Ex: paehtāwāēwesew "He is heard by higher powers" or kāstāhikoyahk "it frightens us". These languages have been extensively studied by Leonard Bloomfield, Ives Goddard, and others. Algonquian nouns have an animate/inanimate contrast: some nouns are classed as animate, while all other nouns are inanimate. There is ongoing debate over whether there is a semantic significance to the categorization of nouns as animate or inanimate, with scholars arguing for it as either a clearly semantic issue, or a purely syntactic issue, along with a variety of arguments in between. More structurally inclined linguistic scholars have argued that since there is no consistent semantic system for determining the animacy of a noun, that it must be a purely linguistic characterization. Anthropological linguists have conversely argued the strong connection between animacy and items viewed as having spiritual importance. Another important distinction involves the contrast between nouns marked as proximate and those marked as obviative. Proximate nouns are those deemed most central or important to the discourse, while obviative nouns are those less important to the discourse. There are personal pronouns which distinguish three persons, two numbers, inclusive and exclusive first person plural, and proximate and obviative third persons. Verbs are divided into four classes: transitive verbs with an animate object, transitive verbs with an inanimate object, intransitive verbs with an animate subject, and intransitive verbs with an inanimate subject.
Vocabulary
Loan words Because Algonquian languages were some of the first with which Europeans came into contact in North America, the language family has given many words to English. Many eastern and midwestern U.S. states have names of Algonquian origin, as do many cities: Milwaukee, Chicago, et al. Ottawa, the capital of Canada, is named after an Algonquian nation, the Odawa people.
