Rinconada Bikol language

Rinconada Bikol or simply Rinconada, spoken in the province of Camarines Sur, Philippines, is one of several languages that compose the Inland Bikol (or Southern Bicol) group of the Bikol macrolanguage. It belongs to the Austronesian language family that also includes most Philippine languages, the Formosan languages of Taiwanese aborigines, Malay, the Polynesian languages and Malagasy.

Rinconada is surrounded by and shares common features with other Bikol languages. It is bordered by Coastal Bikol to the north, Buhinon to the east, and West Miraya language immediately to the south. The language's closest relatives outside the Bicol region are Aklanon, Waray-Waray, and to a lesser extent Tagalog, especially the variants used in Batangas and Marinduque.

Rinconada Bikol is also used by the indigenous population of Agta (Ŋod for camaraderie) in the surrounding mountainous areas of Mount Iriga (old name is Mount Asog) as most of them today are fluent in the language. The Austronesian people that have migrated to the foot of Mount Asog from lowland Nabua introduced the language to the Negritos when they began conducting trade and commerce. Consequently, it has become the native language of many, replacing their original language known as "Inagta". Also known to linguists as Mount Iriga Agta, it is currently considered an endangered language. Inagta is said to have 86% intelligibility with Rinconada Bikol and a lexical similarity of 76%.
