Iban

The Iban language (jaku Iban) is spoken by the Iban, a branch of the Dayak ethnic group formerly known as "Sea Dayak" who live in Sarawak, the Indonesian province of Kalimantan Barat and in Brunei. It belongs to Malayic languages a Malayo-Polynesian branch of the Austronesian language family, and is related to Malay, more closely to Sarawakian Malay.

It is thought that the homeland of the Malayic languages is in western Borneo, where the Ibanic languages remain. The Malayan branch represents a secondary dispersal, probably from central Sumatra but possibly also from Borneo.
