Siouan languages
Authors who call the entire family "Siouan" distinguish the two branches as "Western Siouan" and "Eastern Siouan" or as "Siouan-proper" and "Catawban". Others restrict the name "Siouan" to the western branch and use the name "Siouan–Catawban" for the entire family. Generally, however, the name "Siouan" is used without distinction.
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.
