Inagta Partido (Isarog Agta) or alternatively Katubung[1] is a nearly extinct
Bikol language spoken by a semi-nomadic hunter-gatherer
Agta (
Negrito) people of the
Philippines. It is found on
Mount Isarog east of
Naga City particularly in the town of
Ocampo where the most recent survey of the language was conducted.[2]
According to Lobel (2013),[3] there are no speakers of Inagta Partido under 60. It is a moribund language. The Ethnologue cites a report from 2000 that there were then only five speakers from an ethnic population of about 1,000.[4]
Inagta Partido has borrowed heavily from Bikol languages such as Bikol Naga and Bikol Partido, but has a non-Bikol substratum.[5]
