Siouan languages
Siouan languages can be grouped into the Western Siouan languages and Catawban languages. The Western Siouan languages can be divided into Missouri River languages (such as Crow and Hidatsa), Mandan, Mississippi River languages (such as Dakotan, Chiwere-Winnebago, and Dhegihan languages), and Ohio Valley Siouan branches. The Catawban languages consist only of Catawban and Woccon.
Samoan language
Samoan is an analytic, isolating language and a member of the Austronesian family, and more specifically the Samoic branch of the Polynesian subphylum. It is closely related to other Polynesian languages with many shared cognate words such as "aliʻi", "ʻava", "atua", "tapu" and numerals as well as in the name of gods in mythology.
