Claim: Lampung language has been clearly differentiated from the Malay language.
Evidence: 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.
