Ethnologue lists the following dialects of Falam: • Tlaisun (Shunkla, Sunkhla, Taishon, Tashom, Tashon) • Laizo (Laiso, Laizao, Laizo-Shimhrin) • Zahao (Lyen-Lyem, JaHau Yahow, Zahau, Zahau-Shimhrin, Za-How) • Sim Falam takes its name from a village, founded by the Tlaisun (in English, ) tribe, and Tashon was the original language spoken in Falam. Falam grew in population from the surrounding tribes from Sunthla (also ), Sim and Zahau (also ) that created a new language based on these three tribes, very different from the Tlaisun language. This language was later popularly known as
Laizo. Laizo was recorded as the first language used in the official radio broadcasting dialect of Chin in
Myanmar. In order to be inclusive in Laizo, the name was later changed to Falam, although its official name is still Laizo. Rupini and Koloi are also quite different. Tapong has lower intelligibility with other Falam Chin dialects, having 75%
lexical similarity with Zanniat.
Ethnologue reported the following speaker populations of Falam dialects in 1983: 9,000 Taisun, 16,000 Zanniat, 7,000 Khualsim, 4,000 Lente, 14,400 Zahau, 18,600 Laizo. == Phonology ==
