Bantayanon language
The Bantayanon language is the regional language of the Bantayan islands in the Philippines. It is a part of the Bisayan language family and is closely related to Waray and Hiligaynon. There are three dialects of Bantayanon, based in the three municipalities that comprise the island group: "Binantayanun" (in Bantayan), "Linawisanun" (in Madridejos), and "Sinantapihanun" (in Santa Fe), the most idiosyncratic of the three. There are also significant dialectical differences between the speech patterns of those that live in the town centers and those that live outside of the more rural areas of the islands. History of the  Bantayanon language. The first mention of the language spoken on the Bantayan islands seems to be from the Spanish historian and Jesuit missionary Ignacio Alcina, who wrote in 1668,"Finally, it could have happened that people from various larger or smaller islands passed over to the others, as is an established fact among them. For instance, those on the Island of Bantayan, which is near Cebu, are actually descendants of the people living on Samar Island and on the western side or opposite that of Ibabao. Today, they admit that they are related by blood due to the fact that the  latter were populated in more recent times." (translation by editors)The substratum of Bantayanon is that Old Waray dialect that moved across Bantayan and eventually onto Panay Island, and later Bantayanon was heavily influenced in its lexicon by Cebuano. Modern Scholarship on the Bantayanon language. The only published scholarship on the Bantayanon language is a Master of Arts thesis presented to Mindanao State University - Iligan Institute of Technology (MSU-IIT) by Minda Carabio-Sexon, in which she looks at the lexical relationship between Bantayanon and its neighboring languages, presents findings from mutual-intelligibility tests with related languages, and provides a sociolinguistic  profile of the island’s inhabitants. She also provides transcriptions and English translations of two of her collected interviews. There is currently a documentation project of Bantayanon underway by researcher Jarrette K. Allen, a PhD candidate at Tulane University in New Orleans, LA. Phonology and Orthography. Bantayanon has 16 consonantal phonemes and 3 vocalic phonemes.
