The Lai Tay script (
Names
The Lai Tay script means "the script of the Tai". It is also known by various other names such as the Yo Lai Tay script,[2] Nge An script, Tai Yo script, Thai Lai Tay script, Quy Chau script.[3]
Origin
The scholar Ferlus classifies the Lai Tay script as a part of the Khmer family of writing systems, which the scholar divides into two groups: the central scripts consisting of the ancient Sukhothai and Fakkham scripts, which developed into the modern Thai and Lao scripts, and the peripheral scripts of the Tai peoples of Vietnam, which include the Tai Dam, Tai Don, Tai Daeng, Lai Tay and Lai Pao scripts.[3] Ferlus suggest that the Tai peoples all adopted the same first model of writing borrowed from the Khmers, by simple contact during exchanges, without proper learning. Subsequently, the Tai migrated and occupied a large part of Southeast Asia. The peripheral scripts still retain many characteristics of the primitive Khmer-borrowed script, such as pre-Angkorian sound values of certain letters, a lack of alphabetical order and a lack of numerals.[3] The scripts used by the Tai peoples of Vietnam arrived there as early as the 16th century.[1]
Characteristics
The Lai Tay script has 29 consonants, of which 8 can occur in the syllable final position. The script has 13 vowel signs, which are placed below the consonant for most vowels, or to the right of the consonant for a few other vowels.[3][2] Unlike other Tai writing systems, the Lai Tay script has remained a true abugida, and consonants written without a vowel sign are pronounced with the inherent vowel <o>, [ɔ].[2] The script contains 9 ligatures for vowel and final consonant combinations.[2]
The script is written vertically from top to bottom and horizontally from right to left on the model of
The Lai Tay script does not contain any tone markers. The script is mostly written without any punctuation marks, but they might be found in some manuscripts, where they are the same as traditional Chinese punctuation marks. The script does not contain any numerals, and numbers were traditionally spelled out.[2]

Usage
The Lai Tay script is now out of common use, but there are enough manuscripts to allow linguistic study. Some very old Tai Yo scholars can still read the manuscripts.[3] Manuscripts are preserved in both private and in personal collections. The script is now being taught and studied by the Tai Yo community, with the support of the local government and teachers.[2]
Unicode
The script has been proposed to be encoded by Unicode.[2]
