Claim: Lampung language has been classified inside the "Malayic Hesion" and "Javo-Sumatra Hesion" along with the Malay language.
Evidence: 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. 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.
