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.
West Uvean language
West Uvean (also Uvean or Faga Ouvéa; "Fagauvea" in the vernacular) is a Polynesian outlier language spoken on the island of Ouvéa, in the Loyalty island group of New Caledonia, and in the capital of Nouméa. It has long been in contact with Iaai, the Southern Oceanic language also spoken on the same island. Consequently, four vowels have been added, and the syllable structure has become complex, allowing for final consonants.
