What is the Thai Language?

Thai is the national and official language of Thailand and the mother tongue of the Thai people, Thailand’s dominant ethnic group. Corporate Translations Ltd provide professional Thai translation services to businesses using only native speaking mother-tongue translators.

The national language of Thailand, Thai is a member of the Tai group of the Tai-Kadai language family. The Tai-Kadai languages are thought to have originated in what is now southern China, and some linguists have proposed links to the Austroasiatic, Austronesian, or Sino-Tibetan language families. It is a tonal and analytic language. The combination of tonality, a complex orthography, relational markers and a distinctive phonology can make Thai difficult to learn for those who do not already speak a related language.

Standard Thai, also known as Central Thai or Siamese, is the official language of Thailand, spoken by about 65 million people (1990) including speakers of Bangkok Thai (although the latter is sometimes considered as a separate dialect). Khorat Thai is spoken by about 400,000 (1984) in Nakhon Ratchasima; it occupies a linguistic position somewhere between Central Thai and Isan on a dialect continuum, and may be considered a variant or dialect of either.


The ISO published an international standard for the transliteration of Thai into Roman script in September 2003 (ISO 11940). By adding diacritics to the Latin letters, it makes the transcription reversible, making it a true transliteration. This system is intended for academic use and is hardly ever used in Thailand for the common public.
