Tai Yo language
Kra–Dai language spoken in Vietnam
Tai Yo (Thai: ไทญ้อ), also known as Tai Mène and Nyaw (Thai: ไตเมือง), is a Tai language of Southeast Asia. It is closely related to Tai Pao of Vietnam, where it may have originated. It was once written in a unique script, the Tai Yo script, but that is no longer in use.[1] The language is known regionally in Laos and Thailand as Tai Mène and Tai Nyaw and, in Vietnam as Tai Do (old-fashioned English transcription) and Tai Quy Chau.[4] Superficially, Tai Yo appears to be a Southwestern Tai language but this is only because of centuries of language contact and it is properly classified with the Northern Tai languages.[2] The Nyaw/Nyo spoken in central Thailand and western Cambodia is not the same as Tai Yo.[5]
