Demographics

The official language of Thailand is the Thai language, a Tai-Kadai language closely related to Lao, Shan in Burma, and numerous smaller languages spoken in an arc from Hainan and Yunan south to the Malaysian border. It is the principal language of education and government and spoken throughout the country. The standard is based on the dialect of the Central Thai people, and it is written in the Thai alphabet, an abugida script that evolved from the Khmer script. Several other dialects exist, and coincide with the regional designations. Southern Thai is spoken in the southern provinces, and Northern Thai is spoken in the provinces that were formally part of the independent kingdom of Lannathai.

Thailand is also host to several other minority languages, the largest of which 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 in where it is traditionally spoken was historically part of the Lao kingdom of Lan Xang. In the far south, Yawi, a dialect of Malay, is the primary language of the Malay Muslims. Chinese dialects are also spoken by the large Chinese population, Teochew being the dialect best represented.

Numerous tribal languages are also spoken, including those belonging to the Mon-Khmer family, such as Mon, Khmer, Viet, Mlabri; Austronesian family, such as Cham, Moken, and Orang Asli, Sino-Tibetan family such as Hmong, Lawa, Akhan, and Karen; and other Tai-Kadai languages such as Nyaw, Phu Thai, and Saek.

English is a mandatory school subject, but the number of fluent speakers remains very low, especially outside the cities.
