Cebuano is spoken on the island of Cebu and its 167 surrounding islands and islets, Bohol and Siquijor, eastern Negros Island Region (entire Negros Oriental and northeastern Negros Occidental), southern Masbate, many portions of Leyte, Biliran, parts of Samar and most parts of Mindanao, the second largest island of the Philippines. Furthermore, "a large portion of the urban population of Zamboanga, Davao and Cotabato is Cebuano speaking". Some dialects of Cebuano have different names for the language. Ethnic groups of Cebuano speakers from Cebu are mainly called "Cebuano", Cebuano speakers from Bohol are "Boholano/Bol-anon", while Cebuano speakers in Leyte identify their dialect as Kana (Leyte Cebuano or Leyteno). Speakers in Mindanao and Luzon refer to the language simply as Binisaya or Bisaya. Source: Wikipedia
