潮州語
The largest of Thailand's minority languages is the Lao dialect of Isan spoken in the northeastern provinces. Although sometimes considered a Thai dialect, it is a Lao dialect, and the region where it is traditionally spoken was historically part of the Lao kingdom of Lan Xang. In the far south, Kelantan-Pattani Malay is the primary language of Malay Muslims. Varieties of Chinese are also spoken by the large Thai Chinese population, with the Teochew dialect best-represented.
