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.
Visayan languages
Native speakers of Visayan languages, especially Cebuano, Hiligaynon and Waray not only refer to their language by their local name, but also by "Bisaya" or "Binisaya", meaning "Visayan language". This is misleading or may lead to confusion as different languages may be called "Bisaya" by their respective speakers despite their languages being mutually unintelligible. However, languages that are classified within the Visayan language family but spoken natively in places outside of the Visayas do not use the self-reference "Bisaya" or "Binisaya". To speakers of Masbateño, Romblomanon, Surigaonon and Butuanon, the term "Visaya" usually refers to either Cebuano or Hiligaynon. Since Tausugs are mostly Muslims, they view the term "Bisaya" as a religious term referring to Christian Filipinos (mostly referring to either Cebuano and/or Hiligaynon as they are the neighboring languages).
