Thai language
Thai is the sole official language of Thailand.
Thai, or Central Thai (historically Siamese), is a Tai language of the Kra–Dai language family spoken by the Central Thai, Mon, Lao Wiang, and Phuan people in Central Thailand and the vast majority of Thai Chinese enclaves throughout the country. It is the sole official language of Thailand and the most spoken of over 60 languages of Thailand by both number of native and overall speakers. Over half of its vocabulary is derived from or borrowed from Pali, Sanskrit, Mon and Old Khmer. It is a tonal and analytic language with a complex orthography and system of relational markers.

Lore & Background
Thai has undergone various historical sound changes, with significant changes occurring during the evolution from Old Thai to modern Thai. The Thai writing system has an eight-century history. Old Thai had a three-way tone distinction on live syllables and a two-way voiced vs. voiceless distinction among fricative and sonorant consonants, with up to a four-way distinction among stops and affricates.
Reader's Guide
Thai is the dominant language in all aspects of society in Thailand, initially seeing gradual and later widespread adoption as a second language among the country's minority ethnic groups from the mid-late Ayutthaya period onward. Ethnic minorities today are predominantly bilingual, speaking Thai alongside their native language or dialect. Standard Thai is based on the register of the educated classes by Central Thai and ethnic minorities in the area along the ring surrounding the Metropolis. It is the principal language of education and government and spoken throughout Thailand. The standard is based on the dialect of the central Thai people, and it is written in the Thai script. Thai is partly mutually intelligible with Lao, Isan, and some fellow Thai topolects, and these languages effectively form a dialect continuum.

Frequently Asked Questions

Why is Thai language important?
More than half of its vocabulary is inherited from or borrowed from Pali, Sanskrit, Mon, and Old Khmer, making it a living record of deep regional cultural and religious exchange. It also uniquely encodes social hierarchy through its relational marker system, a feature few other languages replicate.
