Banjarese language

The Banjar or Banjarese (basa Banjar; jaku Banjar, Jawi: باس بنجر) is an Austronesian language predominantly spoken by the Banjarese—an indigenous ethnic group native to Banjar regions— in the southeastern Kalimantan of Indonesia. The Banjarese language is the de facto lingua franca for various indigenous community especially in South Kalimantan, as well as Central Kalimantan (notably in Seruyan Regency and Sukamara Regency) and East Kalimantan in general.

Apart from the native Banjarese in Indonesia, the Banjarese language also spoken by little Banjarese diaspora abroad (such as in Brunei, Malaysia (notably in Sabah and Perak), and Singapore); however, they tend to not use it as their primary language, and their fluency degree is questionable.
