Tai Tham script
abugida script
Tai Tham script (Tham meaning "scripture") is an abugida writing system used mainly for a group of Southwestern Tai languages i.e., Lanna, Tai Lü, Khün and Lao; as well as the liturgical languages of Buddhism i.e., Pali and Sanskrit. It is historically known as Tua Tham (ᨲ᩠ᩅᩫᨵᨾ᩠ᨾ᩼ or ᨲ᩠ᩅᩫᨵᩢᨾ᩠ᨾ᩼). In Thailand and Myanmar, the script is often referred to as Lanna script (Thai: อักษรธรรมล้านนา RTGS: Akson Tham Lanna; Burmese: လန်နာအက္ခရာ, MLCTS: Lanna Akhkara) in relation to the historical Lanna Kingdom situating in the Northern region of modern-day Thailand and Kengtung, Shan state in Myanmar. Local people in Northern Thailand also call the script as Tua Mueang (ᨲ᩠ᩅᩫᨾᩮᩥᩬᨦ, Northern Thai pronunciation: [tǔa̯.mɯ̄a̯ŋ] ) in parallel to Kam Mueang, a local name for Lanna language. In Laos and Isan region of Thailand, a variation of Tai Tham script, often dubbed Lao Tham, is also known by the locals as To Tham Lao (Northeastern Thai: โตธรรมลาว /toː˩.tʰam˧˥.laːw˧/, cf. Lao: ໂຕທຳ/ໂຕທັມ BGN/PCGN to tham) or Yuan script. Tai Tham script is traditionally written on a dried palm leaf as a palm-leaf manuscript.
The Lanna language is a close relative of (standard) Thai. It is spoken by nearly 6 million people in Northern Thailand and several thousand in Laos of whom few are literate in Lanna script. The script is still read by older monks.
This brief starts where responsible research should: with the source description of “Tai Tham script” as abugida script. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as abugida script. Its deeper value depends on whether names, dates, institutions and citations support that framing.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Aug 23, 2026. The linked authority identifier is Q1314503. The Library of Congress control number is sh2017004359. 1 of 2 selected statements include explicit references; 1 carry qualifiers and 0 use preferred rank.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
