problematic. There is some resurgent interest in the script among younger people, but an added complication is that the modern spoken form, called Kam Muang, differs in pronunciation from the older form. There are 670,000 speakers of Tai Lü, some of those born before 1950 are literate in Tham, also known as Old Tai Lue. The script has also continued to be taught in the monasteries. The New Tai Lue script is derived from Tham. There are 120,000 speakers of Khün for which Lanna is the only script.


History

The Tai Tham script shows a strong similarity to the Mon script used by the Mon kingdom of Haripunjaya around the 13th century CE, in the present-day

and Sipsong Panna. Numerous local variants developed, such as the ''Lue'' variant (Sipsong Panna), the ''Khuen'' variant (Shan State) and the ''Tham Lao'' variant (Laos and Isan). The variants differ only slightly in appearance, and the system of writing has remained the same. As the name suggests, the use of the Tham (Dharma) script in Lao was restricted to religious literature, either used to transcribe Pali, or religious treatises written in Lao intended solely for the clergy. Religious instructional materials and prayer books dedicated to the laity were written in Tai Noi instead. As a result, only a few people outside the temples were literate in the script. In

Consonants

There are 43 Tai Tham consonants. They are divided into three groups: categorized consonants (ᨻ᩠ᨿᩢᨬ᩠ᨩᨶᨶᩲᩅᩢᨣ᩠ᨣ᩼, ''payanjana​ nai wak''), non-categorized consonants (ᨻ᩠ᨿᩢᨬ᩠ᨩᨶᩋᩅᩢᨣ᩠ᨣ᩼, ), and additional consonants (ᨻ᩠ᨿᩢᨬ᩠ᨩᨶᨲᩮᩬᩥ᩵ᨾ, ''payanjana tueam''). Categorized consonants and non-categorized consonants are those derived from

Consonant chart

There are 25 categorized consonants, 10 non-categorized consonants, and 8 additional consonants. Similar to Khmer, Tai Tham also has a subjoined form called ''haang'' (ᩉᩣ᩠ᨦ), ''tua joeng'' (ᨲ᩠ᩅᩫᨩᩮᩥ᩠ᨦ), or ''tua hoy'' (ᨲ᩠ᩅᩫᩉᩬ᩠ᨿ᩶). In the Unicode input method, ''sakot sign'' (U1A60) (◌᩠) is used to trigger the subjoined forms. The additional consonants are shown in yellow. These consonants have the characteristics of lacking the subjoined form. Similar to

, consonants in Tai Tham can be classified into high, mid, and low classes regarding to the tone rules. ; Notes


Consonant combinations and ligatures


Consonant digraph with ''Ha''

Certain consonants in the low-class group lack their high-class counterpart. These consonants are sometimes called the ''single low-class consonants''. Their high-class counterparts are created by the combination with letter ''high Ha'' (ᩉ) as a digraph, called ''Ha Nam'' (ᩉ​ ᨶᩣᩴ). ; Notes


Special letters

;Notes


Vowels

Vowel characters come in two forms: as stand-alone letters for writing initial vowels or as diacritics that can be attached to all sides of the consonant letters. However, Lanna excels in terms of the number of diacritics used. Some vowel sounds can be written with a combination of as many as four diacritics: one on each side of the consonant.


Dependent vowels


Independent vowels

Independent vowels are mainly reserved for writing

Relation with other scripts

Tai Tham is very similar in shape to Burmese script since both are derived from Old Mon script. New Tai Lue is a descendant of Tai Tham with its shape simplified and many consonants are removed. Thai script looks distinctive to Tai Tham but covers all equivalent consonants including the 8 additional consonants as Thai is the closest sister language to Northern Thai, Khuen, and Lue languages. A variation of Thai script ( Sukhothai script) called Fakkham script was also used in
