Geographic extent of Central Luzon languages based on Ethnologue
The Central Luzon languages are a group of languages belonging to the Philippine languages. These are predominantly spoken in the western portions of Central Luzon in the Philippines. One of them, Kapampangan, is the major language of the Pampanga-Mount Pinatubo area. However, despite having three to four million speakers, it is threatened by the diaspora of its speakers after the June 1991 eruption of that volcano. Globalization also threatened the language, with the younger generation more on using and speaking Tagalog and English, but promotion and everyday usage boosted the vitality of Kapampangan.[1] Another Central Luzon language, Sambal or Sambali, experiences same situation, the speakers of the language are decreasing due to the globalization that many of the speakers of younger generation are shifting to Tagalog & Ilocano. The only Central Luzon language spoken outside Central Luzon is Hatang Kayi or Sinauna, located in northeast Calabarzon.
Historical linguistics
The modern Central Luzon languages descended from the hypothetical Proto-Central Luzon language.
The phonetic values of the consonants above are the ones assumed for Proto-Austronesian[3] except for the glottal stop /ʔ/, which resulted from sound changes into Proto-Central Luzon: *q > *ʔ and *h > Ø followed by Ø > *ʔ/#_.[2]
The values of the vowels above are the ones they had in Proto-Malayo Polynesian.[3]
External relationships
Ronald Himes (2012)[2] and Lawrence Reid (2015)[4] suggest that the Northern Mindoro languages may group with the Central Luzon languages. Both branches share the phonological reflex Proto-Austronesian *R > /y/.
