McFarland (1974)

Curtis McFarland gives the following classification for the Bikol languages.^[1]

Lobel (2000)

Clockwise from top-left: A signage barring people from hanging around the area; A signage barring vendors inside the churchyard; A signage reminding people of proper waste disposal; and a signage barring swimmers in Lake Bato. All are written in the Coastal Bikol language (Naga–Legazpi variant).

While McFarland (1974) splits Bikol into 11 dialects, Lobel (2000) splits Bikol into 12 different dialects (including Partido Bikol, which McFarland does not differentiate) and 4 main branches.^[2]

Some dialects of Southern Bikol have the close central unrounded vowel /ɨ/ as a reflex of Proto-Austronesian *ə. However, Proto-Austronesian *ə is realized as /o/ in Libon. Two Bikol dialects have unique additional consonants, namely Southern Catanduanes, which has an interdental lateral consonant /l̟/ (also transcribed as l̪͆),^[3][4] and Buhi-non, which has the voiced velar fricative /ɣ/.^[5]
