History of the Thai language
Thai is the national language of Thailand, spoken by around eighty percent of the sixty million residents of the South-East Asian country. Linguists consider it an “uninflected, primarily monosyllabic, tonal language” in the “Tai-Kadai family.” The spoken language is believed to have originated in the area which is now the border between Vietnam and China, an idea which provides clues to the origin of the Thai people, an area of continued scholarly debate. Linguistically, the language is related to languages spoken in eastern Burma (Myanmar), northern Vietnam, Yunnan, and Laos.
