Kayah or Kayah Li is a member of Karen branch of the Sino-Tibetan language family. It is spoken by about 210,000 people in the Kayah and Karen states of Burma (Myanmar). The language and people who speak it are also known as Western Kayah, Karenni, Karennyi, Red Karen, Yang Daeng or Karieng Daeng.
The Kayah Li alphabet was devised by Htae Bu Phae in March 1962. It is taught in schools in refugee camps in Thailand. It appears to be modelled, to some extent, on scripts such as Thai and Burmese.
