Origin of Kirghizorigin, originally uncertain
Possibly from the Kyrgyz words "кырк кыз" (forty girls), a reference to the Manas epic unifying forty small tribes against the Chinese and the Muslim expansion; or possibly from "кырк ууз" (the forty tribes); or possibly from "кыргыс" (imperishable, inextinguishable, undying).
