Lampung or Lampungic (cawa Lampung) is an Austronesian language or dialect cluster with around 1.5 million native speakers, who primarily belong to the Lampung ethnic group of southern Sumatra, Indonesia. It is divided into two or three varieties: Lampung Api (also called Pesisir or A-dialect), Lampung Nyo (also called Abung or O-dialect), and Komering. The latter is sometimes included in Lampung Api, sometimes treated as an entirely separate language. Komering people see themselves as ethnically separate from, but related to, Lampung people. Lampung, which means 'one land of two traditions', is Sang Bumi Lampung with the nickname Sang Bumi Ruwa Jurai. Although Lampung has a relatively large number of speakers, it is a minority language in the province of Lampung, where most of the speakers live. Concerns over the endangerment of the language has led the provincial government to implement the teaching of Lampung language and script for primary and secondary education in the province. Lampung is part of the Malayo-Polynesian branch of Austronesian family, although its position within Malayo-Polynesian is hard to determine. Language contact over centuries has blurred the line between Lampung and Malay, to the extent that they were grouped into the same subfamily in older works, such as that of Isidore Dyen in 1965, in which Lampung is placed inside the "Malayic Hesion" alongside Malayan (Malay, Minangkabau, Kerinci), Acehnese and Madurese. Nothofer (1985) separates Lampung from Dyen's Malayic, but still include it in the wider "Javo-Sumatra Hesion" alongside Malayic, Sundanese, Madurese, and more distantly, Javanese. Ross (1995) assigns Lampung its own group, unclassified within Malayo-Polynesian. This position is followed by Adelaar (2005), who excludes Lampung from his Malayo-Sumbawan grouping—which includes Sundanese, Madurese, and Malayo-Chamic-BSS (comprising Malayic, Chamic, and Bali-Sasak-Sumbawa languages).
