Claim: Astronesian language Lampung has been classified in the "Malayic Hesion" and "Javo-Sumatra Hesion" along with the Malay language, mostly spoken in Brunei, Indonesia, Malaysia and Singapore.
Evidence: 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. 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. Malay (/məˈleɪ/; Malay: bahasa Melayu, بهاس ملايو‎) is an Austronesian language officially spoken in Brunei, Indonesia, Malaysia and Singapore, and unofficially spoken in East Timor and parts of Thailand.
