Іригська біколано

Iriga Bicolano (Rinconada Bikol, autonymously Rinconada) is a Bikol Austronesian language spoken by ~250,000 people in the Rinconada district of Camarines Sur Province in the Bicol Region of Luzon, Philippines. Although traditionally classified as a dialect of Bikol Central (bik), Rinconada is in fact a distinct language not mutually intelligible with Standard Bikol Central spoken in Naga City. Its most distinctive linguistic feature is the schwa vowel ə (written ë in some orthographies), which contrasts with the simpler 5-vowel system of Bikol Central — this gives Rinconada words like aldəw 'sun' vs Bikol Central aldaw. The Bikol cluster includes ~12 distinct varieties; modern Lobel (2013) treatment classifies Rinconada as one of the Inland Bikol languages. Despite its 250K speakers, Rinconada faces pressure from Standard Bikol Central in education and media.
