Algonquian languages
The languages assigned to the Eastern Algonquian group are hypothesized to descend from an intermediate common ancestor proto-language, referred to as Proto-Eastern Algonquian (PEA). By virtue of their common ancestry, the Eastern Algonquian languages constitute a genetic subgroup, and the individual Eastern Algonquian languages descend from PEA. By contrast, other Algonquian languages are hypothesized to descend directly from Proto-Algonquian, the ultimate common language ancestor of the Algonquian languages.
