New Tai Lue script, also known as Xishuangbanna Dai[1] and Simplified Tai Lue, is an alphabet used to write the Tai Lü language. Developed in China in the 1950s, New Tai Lue is based on the traditional Tai Tham alphabet developed c. 1200. The government of China promoted the alphabet for use as a replacement for the older script; teaching the script was not mandatory, however, and as a result many are illiterate in New Tai Lue. In addition, communities in Burma, Laos, Thailand and Vietnam still use the Tai Tham alphabet.

Consonants
