The Bisayan languages or Visayan languages are a subgroup of the Austronesian languages spoken in the Philippines. They are most closely related to Tagalog and the Bikol languages, all of which are part of the Central Philippine languages. Most Bisayan languages are spoken in the whole Visayas section of the country, but they are also spoken in the southern part of the Bicol Region (particularly in Masbate and Sorsogon where several dialects of Waray are spoken), islands south of Luzon, such as those that make up Romblon, most of the areas of Mindanao and the province of Sulu located southwest of Mindanao. Some residents of Metro Manila also speak one of the Bisayan languages. Over 30 languages constitute the Bisayan language family. The Bisayan language with the most speakers is Cebuano, spoken by 20 million people as a native language in Central Visayas, parts of Eastern Visayas, and most of Mindanao. Two other well-known and widespread Bisayan languages are Hiligaynon (Ilonggo), spoken by 9 million in most of Western Visayas and Soccsksargen; and Waray-Waray, spoken by 6 million in Eastern Visayas region. Prior to colonization, the script and calligraphy of most of the Visayan peoples was the badlit, closely related to the Tagalog baybayin. Nomenclature Native speakers of most Bisayan languages, especially Cebuano, Hiligaynon and Waray, not only refer to their language by their local name, but also by Bisaya or Binisaya, meaning Bisayan 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 Bisayan language family but spoken natively in places outside of the Visayas do not use the self-reference Bisaya or Binisaya. To speakers of Cuyonon, Surigaonon, Butuanon and Tausug, the term Visayan usually refers to either Cebuano or Hiligaynon. There have been no proven accounts to verify the origins of Bisaya. However, there is an ethnic group in Malaysia and Brunei who call themselves with the same name. However, these ethnic groups in the Philippines must not be confused with those in Borneo. Evidence David Zorc lists the following innovations as features defining the Bisayan languages as a group (Zorc 1977:241). Tausug is noted to have diverged early from the group and may have avoided some sound changes that affected the others. *lC, *Cl > *Cl (where C is any consonant not *h, *q,
