The Lanna script is a descendant of the Old Mon script like the Lao religious scripts and Burmese script. It was used to write the Lanna language (also called Northern Thai or Kam Muang - คำเมือง). It was used during the time of the Lanna kingdom, founded in 1259 and conquered by Burma in 1558. The script is also known as Tham or Yuan.
The Lanna alphabet is used to write Northern Thai (Kam Mu'ang), Tai Lue and Khün languages. It is also used for religious purposes to write Lao Tham (Old Lao), and can be found as the alphabet of old manuscripts in temples in Northern Thailand.
The Lanna language (ล้านนา) is a close relative of Thai and member of the Chiang Saeng languages. It is spoken by about six million people in northern Thailand and several thousand in Laos, but nowadays it is written with the Thai alphabet.
Consonants are divided into three classes which help to determine the tone of a syllable (indicated by the numbers below). In the chart below is given first the Lanna letter, then the "Payanchana Sagot พยัญชนะสะกด" if it exists (shown with the letter as a place holder), then the Thai equivalent, then the English equivalent (followed by IPA in square brackets). The numbers indicate the class of the consonant (used in determining the tone of the syllable). 1 high, 2 mid, 3 low.

The vowels in the first column are the diacritic marks used to modify consonants. In the second column are the corresponding independent forms. Only certain vowels have this form. These are used for writing words borrowed from Pali. The third column is the Thai equivalent and the fourth is IPA. The dash in the Lanna column indicates the position of the consonant that the vowel is attached to.
Lanna has two sets of numerals. The first set, Lek Nai Tam, is reserved for special purposes such as religious texts. The second set, Lek Hora, is the set usually used in everyday life. Its name (Hora) suggests that it is also used for astrological purposes.
The dash indicates the position of the letter that the diacritic mark is attached to.
