The Northern Philippine languages are the languages of central and northern Luzon, and the small islands between Luzon and Formosa, including Ilokano, Pangasinan, Kapampangan, and the Yami language of Taiwan.
The Northern Philippine languages are a long-established group which has often been taken to be more a geographic convenience than linguistic reality. However, a 2008 analysis of the Austronesian Basic Vocabulary Database fully supported the unity of the languages as a family. It also provided a low level of support (at 60% confidence) that the Batanic branch is closest to Northern Luzon. The Northern Mindoro branch was not included in the analysis.
