Enrekang, Duri and Maiwa are three closely related languages that border each other. Some consider them to be dialects of a single language called Massenrempulu.
Enrekang has eastern and western dialects. The western dialect is usually referred to as Pattinjo. A possible third dialect, spoken in Ranga village (in Enrekang District), has been reported but not verified (Valkama 1987:128).
A 1986 survey estimated 50,000 speakers of Enrekang (reported in Grimes 1996:659).
