The 70 languages of the Daic, or Tai-Kadai family are spoken in an area to the east of the Austro-Asiatic languages in Indo-China. They include two official languages: Thai (the mother tongue of up to 25 million people in Thailand) and Lao (spoken by 4 million people in Laos, of which it is the official language). Attempts are being made to link the Tai languages to either the Sino-Tibetan or the Austronesian families.
