The Origin of Thai Script: From Khmer to Modern Thai
Thai script (อักษรไทย) originated in the 13th century, created by King Ramkhamhaeng of the Sukhothai Kingdom in 1283. It was modeled after the Khmer script, which ultimately derived from the Brahmi writing system of India. This writing system has been in use for over 700 years; while it has undergone improvements, its core has remained unchanged.
Understanding the origin of Thai script is not only an interesting piece of cultural knowledge but also helps in comprehending some seemingly "peculiar" rules in the Thai writing system.

Brahmi Script
The Brahmi script is the source of almost all South Asian and Southeast Asian writing systems:
| Influenced Script | Region |
|---|---|
| Devanagari | India |
| Burmese | Myanmar |
| Khmer | Cambodia |
| Lao | Laos |
| Thai | Thailand |
Influence of Khmer Script
The Khmer Empire (Angkorian period) once ruled large parts of Southeast Asia, and its script directly influenced Thai script:
- Basic shapes of consonant letters
- Concept of vowel markers
- Writing direction (left-to-right)
💡 This is also why the letters of Thai and Khmer (Cambodian) look similar.
King Ramkhamhaeng and the Creation of Thai Script
Historical Background
In 1283, King Ramkhamhaeng of the Sukhothai Kingdom created the Thai alphabet. According to the famous "Ramkhamhaeng Inscription":
"In the year 1205 (Thai calendar)... King Ramkhamhaeng created these Thai letters"
This is one of the most important cultural achievements in Thai history.
Reasons for Creation
| Need | Solution |
|---|---|
| Need to write Thai language | Create a specialized script |
| Khmer script unsuitable for Thai | Improve to adapt to Thai phonetics |
| Unify script to promote unity | Establish national identity |
The Ramkhamhaeng Inscription
This inscription is the earliest Thai language document:
| Content | Significance |

Evolution of Thai Script
Major Stages
| Period | Characteristics |
|---|---|
| Sukhothai Period (1283-1350) | Original Thai script, simpler letter forms |
| Ayutthaya Period (1350-1767) | Letter forms gradually standardized |
| Thonburi-Rattanakosin Period (1767-Present) | Modern standard form |
Example of Character Form Changes
The letter forms of early Thai and modern Thai are somewhat different:
| Early Form | Modern Form | Explanation |
|---|---|---|
| More rounded | More angular | Changes in writing tools |
| More variations | Standardized | Influence of printing technology |
Modern Standardization
In 1942, the Thai government undertook a modernization reform of the Thai script:
- Abolished 2 rarely used consonants (ฃ, ฅ)
- Simplified some spelling rules
- Standardized printing fonts

Relationship Between Thai and Neighboring Scripts
With Lao Script
Lao script is Thai script's closest "relative":
| Comparison | Thai Script | Lao Script |
|---|---|---|
| Number of Consonants | 44 | 27 |
| Letter Forms | More complex | More simplified |
| Interoperability | Thai learners find Lao easier to learn | Lao learners find Thai easier to learn |
With Khmer Script
| Comparison | Thai Script | Khmer Script |
|---|---|---|
| Relationship | Derived from Khmer | Prototype |
| Letter Forms | Similarities exist | Older forms |
| Tones | Has tone marks | None (non-tonal language) |
With Burmese Script
Although both belong to the Brahmi system, their development paths differ:
| Comparison | Thai Script | Burmese Script |
|---|---|---|
| Letter Forms | Many straight lines and angles | Many circles |
| Appearance | More angular | Rounded |
| Similarity | Low | - |
Unique Design of Thai Script
Tone Marking System
Thai is a tonal language, requiring tone marking. The solution in Thai script:
| Element | Function |
|---|---|
| Consonant classes (high, middle, low) | Base tone |
| Tone marks (4) | Modify tone |
| Syllable type | Influences tone |
This triple system is a unique design of Thai script.
Vowel Placement
Thai vowels can appear in different positions relative to consonants:
| Position | Origin | Example |
|---|---|---|
| Pre-consonant | Indian script tradition | เ-, แ- |
| Above-consonant | Space utilization | -ิ, -ี |
| Below-consonant | Space utilization | -ุ, -ู |
| Post-consonant | Natural writing order | -า |
| Circumfixed | Combined form | เ-า |
Reasons for 44 Consonants
Why does Thai have 44 consonants, many of which have the same pronunciation?
| Reason | Explanation |
|---|---|
| Distinguish loanwords | Differentiates loanwords from Sanskrit/Pali with different origins |
| Historical pronunciation | May have had different pronunciations historically |
| Writing tradition | Maintains connection with ancient documents |
For example: ส, ศ, ษ all pronounce as 's' sound, but are used for different Sanskrit letters in loanwords.

Frequently Asked Questions (FAQ)
Q: Can Thai and Lao scripts be mutually understood?
Partially. Thai and Lao scripts share a common ancestor and have similar letters. It's relatively easy for Thai speakers to learn Lao, but they cannot directly read it. It's similar to the relationship between Chinese and Japanese Kanji – there's a connection, but not full mutual intelligibility.
Q: Why does Thai have so many consonants?
To distinguish different origins of loanwords. Thai borrowed heavily from Sanskrit, Pali, and Khmer. Homophonous letters from different origins are represented by different Thai consonants. Although they now have the same pronunciation, different spellings help in understanding etymology and correct writing.
Q: Did King Ramkhamhaeng "invent" or "adapt" the Thai script?
Primarily adapted and systematized. He took the Khmer script as a base, adjusted and systematized it according to the phonetic characteristics of the Thai language, creating a writing system suitable for Thai. This was a creative adaptation process, rather than a complete new invention.
Q: Will Thai script be simplified in the future?
Unlikely. The 1942 reform was the most recent official adjustment. Thai script is an important part of Thai national identity, and large-scale simplification would face cultural resistance. While the current system is complex, Thai people are accustomed to using it.
