External relationship 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). and Lampung scripts Among the Javo-Sumatran languages, Nothofer mentions that Sundanese is perhaps the closest to Lampung, as both languages share the development of
Proto-Malayo-Polynesian (PMP) *R >
y and the metathesis of the initial and medial consonants of
Proto-Austronesian * > Sundanese 'desire, tired' and Lampung
palay 'hurt of tired feet'. While the Javo-Sumatran/Malayo-Javanic grouping as a whole has been criticized or outright rejected by various linguists, a closer connection between Lampung and Sundanese has been supported by Anderbeck (2007), on the basis that both languages share more phonological developments with each other than with Adelaar's Malayo-Chamic-BSS. Smith (2017) notes that Lampung merges PMP *j with *d, which is a characteristic of his tentative
Western Indonesian (WIn) subgroup. However, lexical evidence for its inclusion in WIn is scant. Smith identifies some WIn
lexical innovations in Lampung, but it is hard to tell whether these words are inherited from Proto-WIn or borrowed later from Malay. While Smith supports its inclusion in the WIn subgroup, he states that the matter is still subject to debate.
Dialects Lampung dialects are most commonly classified according to their realizations of Proto-Lampungic final *a, which is retained in some varieties, but realized as in others. This dichotomy leads to the labeling of these as A-dialect and O-dialect, respectively. Walker (1975) uses the names Pesisir/Paminggir for the A-dialect and Abung for the O-dialect, but Matanggui (1984) argues that these are
misnomers, as each of them is more commonly associated with a specific
tribe instead of the whole dialect group. Anderbeck and Hanawalt use the names
Api for Pesisir and
Nyo for Abung, after their respective words for 'what'. There are some lexical differences between these dialects, but they are identical in terms of morphology and syntax. Walker (1976) further subdivides Abung into two subdialects: Abung and Menggala, while splitting the Pesisir group into four subdialects: Komering, Krui, Pubian, and Southern. Aliana (1986) gives a different classification, listing a combined total of 13 different subdialects within both groups. Through
lexicostatistical analysis, Aliana finds that the Pesisir dialect of Talang Padang shares the most similarities with all dialects surveyed; in other words, it is the least divergent among Lampung varieties, while the Abung dialect of Jabung is the most divergent. However, Aliana does not include Komering varieties in his survey of Lampung dialects, as he notes that some people do not consider it part of Lampung. Hanawalt (2007) largely agrees with Walker, only that he classifies Nyo, Api, and Komering as separate languages rather than dialects of the same language based on sociological and linguistic criteria. He notes that the biggest division is between the eastern (Nyo) and western (Api and Komering) varieties, with the latter forming an enormous
dialect chain stretching from the southern tip of Sumatra up north to the downstream regions of
Komering River. Some Lampungic-speaking groups (such as the Komering and Kayu Agung peoples) reject the "Lampung" label, although there is some understanding among them that they are "ethnically related to the Lampung people of Lampung Province". While many researchers consider Komering as part of Lampung Api, Hanawalt argues that there is enough linguistic and sociological differences to break down the western chain into two or more subdivisions; he thus proposes a Komering dialect chain, separate from Lampung Api. ==Demography and status==
