These languages have similarities with Javanese, which several classifications have taken as evidence of a relationship between them. However, the similarities are with the "high" registers (formal language/royal speech) of Balinese and Sasak; when the "low" registers (commoner speech) are considered, the connection appears instead to be with Madurese and Malay. (See Malayo-Sumbawan languages.)
The position of the Bali–Sasak–Sumbawa languages within the Malayo-Polynesian languages is unclear. Adelaar (2005) assigned them to a larger "Malayo-Sumbawan" subgroup, [2] but this proposal remains controversial.[3][4]
