Karenni language

Karenni or Red Karen, known in Burmese as Kayah, is a Karen dialect continuum spoken by over half a million Kayah people in Burma.
The name Kayah has been described as "a new name invented by the Burmese to split them off from other Karen".
Eastern Kayah is reported to have been spoken by 260,000 in Burma and 100,000 in Thailand in 2000, and Western Kayah by 210,000 in Burma in 1987. They are rather divergent. Among the Western dialects are Yintale and kayahManu.
