佤语支语言分布在缅甸掸邦、泰国北部和中国云南省。
Gérard Diffloth在一份1980年的论文中构拟了原始佤语，他给出的系属分类如下(Sidwell 2009)。
掸邦最近发现的蒙云语和萨怀克语[2][3]也属于佤语丛。
掸邦其他佤语支语言还有嗯语（En）和萨姆语（Siam、Hsem），[4][5]见Scott (1900)[6]。Hsiu (2015)[7]将Scott (1900)中的嗯语（En）、颂语（Son）和蒙雷语归为佤语支，并归纳佤语支的共同创新为原始佤德昂语*s->h-。
Jackson T.-S. Sun（2020）对 拉维瓦语（Lavïa） 进行了研究，分布在云南和缅甸边境两侧，[8]
