Central Bikol

Central Bikol, commonly called Bikol Naga or simply Bikol, is an Austronesian language spoken by the Bicolanos, primarily in the Bicol Region of southern Luzon, Philippines. It is spoken in the northern and western part of Camarines Sur, the second congressional district of Camarines Norte, the eastern part of Albay, the northeastern part of Sorsogon, San Pascual town in Masbate, and the southwestern part of Catanduanes. Central Bikol speakers can be found in all provinces of Bicol, and it is a majority language in Camarines Sur. The standard sprachraum form is based on the Canaman dialect. The language has also speakers outside their native regional homeland, especially in Metro Manila, Mindoro, Palawan, and Mindanao (particularly in Mati, Davao Oriental)

Central Bikol features some vocabulary not found in other Bikol languages nor in other members of the Central Philippine language family like Tagalog and Cebuano. Examples are the words matua and bitis, which are the same as the Kapampangan words meaning 'older' and 'foot, feet', respectively. The word banggi ('night') is another example of this as it is different from the usual Bikol word gab-i but closer to the word bengi of Kapampangan. There is no formal study on the relationship of the Central Luzon languages to Central Bikol but the latter has several words that are also found in the archaic form of Tagalog spoken in the Rizal and Quezon provinces that are believed to be the home of Central Luzon languages such as Kapampangan in Pampanga and southern Tarlac, and Sambalic languages in Zambales province.

Because of its broad geographic coverage as compared with other Bikol languages separated by islands and mountains, Central Bikol diverged into six dialects, which are still mutually comprehensible. The division of the language into different dialects is mainly because of the influence of other Bikol and non-Bikol languages surrounding the region.

The Canaman dialect, despite being used by only a small portion of the population in Camarines Sur, is the standard form of Central Bikol used in literature, Catholic religious rites and mass media. Naga City dialect is spoken in the first, second, and third districts (except in Del Gallego, where residents are mostly Tagalog speakers), and in the western and eastern portions of the fourth district (Caramoan, Garchitorena, Presentacion, Siruma and Tinambac) of Camarines Sur. It is also spoken in San Pascual, Masbate (Burias Island) and the southwestern part of Catanduanes. The Partido dialect is spoken in the eastern part of Camarines Sur centered in the southern portion of the fourth districts (Goa, Lagonoy, Sagñay, San Jose, and Tigaon). The Tabaco-Legazpi-Sorsogon (TLS) dialect is spoken in the eastern coast of Albay and the northeastern part of Sorsogon. TLS is the dialect that has been most influenced by the Inland Bikol languages. The Daet dialect, on the other hand, is spoken in the second district of the province of Camarines Norte. The Virac dialect (or Viracnon language) is spoken around Virac, Catanduanes and surrounding towns on the southeastern part of the island of Catanduanes.

The following table shows the sentence "Why did Pedro's bird not fly even though there is no lock to the cage?" translated to different dialects of Central Bikol along with some other languages in the region.

Like other Philippine languages, Bikol has a number of loanwords, largely Spanish ones as a result of Spanish rule in the Philippines. These include swerte (suerte, 'luck'), karne (carne, 'meat'), imbestigador (investigador, 'investigator'), litro ('liter'), pero ('but'), and krimen (crimen, 'crime'). Another source of loanwords in Bikol is Sanskrit, with examples including words like bahala ('responsibility') and karma.

There are 16 consonants in the Bikol language: /m, n, ŋ, p, t, k, ʔ, b, d, ɡ, s, h, l, w~ʋ, ɾ, j~ʝ/. Eight sounds are borrowed from loanwords: /f, v, ɲ, tʃ, dʒ, ʃ, ʒ, ʎ/.

The sound system of the language according to Mintz in 1971 is as follows.
