Maiwa, Duri and Enrekang are three closely related, mutually bordering languages that some consider to be dialects of a single language called Massenrempulu.
The dialect situation within Maiwa itself is little known; Valkama (1987:128) indicates three dialects (Maroangin, Matakali and Bungin) in Enrekang Regency alone, but failed to collect data on Maiwa communities in the adjoining Sidenreng Rappang (Sidrap) Regency.
An SIL estimate, probably dating from a 1986 survey, placed the number of Maiwa speakers at 50,000 (reported in Grimes 1996:662).
