Isan language
Isan (or
Isaan or
Esarn) is the language of the
Isan region of
Thailand. It is a tonal language of the
Tai family, and is closely related to
Lao, but has also been much influenced by
Thai. It was previously written using the Lao script, but is now normally written in the Thai script. The rules for determining tones vary in each
dialect, but generally they closely resemble those in Lao.
