Classification
Duri, Enrekang and Maiwa are three closely related languages which some consider to be dialects of a single language called Massenrempulu. From a lexicostatistical perspective, Duri can be viewed as transitional between Enrekang to its south and Sa'dan Toraja to its north (K. Valkama 1987:128).
Dialects
Dialectal differences across the Duri area are minor, although S. Valkama (1991:4) distinguishes three dialects: Cakke-Kalosi, the prestige dialect which is centrally located along the main road to Toraja; Baraka, spoken in the southeast of the Duri language area; and Benteng Alla, spoken on the Torajan border. In fact it may be debated whether Benteng Alla should be considered a dialect of Duri or of Sa'dan Toraja.
Population
Recent estimates place the number of Duri at 122,000 (Suryadinata, Arifin and Ananta 2003:8).
