Thai Writing System: Left-to-Right or All Over the Place?
Thai is written from left to right, but vowels can appear above, below, before, or after consonants, or even surround them, making beginners feel like Thai script is "all over the place." Another unique feature is that Thai does not use spaces between words, which adds to the challenge of reading.
Understanding the logic of the Thai writing system can help you learn to read and write Thai faster. It's actually more systematic than it appears.
Basic Rules of Thai Writing
Writing Direction
The basic writing direction for Thai is left-to-right, top-to-bottom, consistent with English.
สวัสดีครับ → Read from left to right
But Why Does It Seem "Messy"?
| Confusing Aspect | Reason |
|---|---|
| Vowels before consonants | Historical writing tradition |
| Tone marks above | Efficient use of space |
| No spaces between words | Writing tradition |
| Letters combined vertically | Saves horizontal space |
Vowel Placement Rules
Four Positions
| Position | Vowel Type | Example |
|---|---|---|
| After consonant (right) | า, ะ, อ etc. | กา, กะ, กอ |
| Before consonant (left) | เ, แ, โ, ไ, ใ | เก, แก, โก |
| Above consonant | ิ, ี, ึ, ื etc. | กิ, กี, กึ |
| Below consonant | ุ, ู | กุ, กู |
| Surrounding | เ-า, เ-ือ etc. | เกา, เกือ |
Writing Order vs. Pronunciation Order
Key understanding: Writing order and pronunciation order are different!
| Word | When writing | When pronouncing |
|---|---|---|
| เก | Write ก first, then เ | Pronounce 'g' first, then 'ee' |
| แม | Write ม first, then แ | Pronounce 'm' first, then 'ɛɛ' |
| โต | Write ต first, then โ | Pronounce 'dt' first, then 'oo' |
Why are Vowels Placed Before?
This is a tradition inherited from Indian writing systems:
- The Brahmi system in India already had pre-vowels.
- Khmer script also shares this characteristic.
- Thai script has preserved this tradition.
💡 Once you get used to it, you'll find that pre-vowels are actually easy to recognize because of their unique shapes.
No Spaces? How to Segment Words?
Space Usage in Thai
| Situation | Use space? |
|---|---|
| Between words | ❌ No |
| Between sentences | ✓ Yes |
| Between paragraphs | ✓ New line |
| Between numbers and text | ✓ Can use |
Example
ฉันไปกินข้าวที่ร้านอาหาร
(I go eat rice at the restaurant)
Segmentation: ฉัน | ไป | กิน | ข้าว | ที่ | ร้าน | อาหาร
No spaces separating words!

Tone Mark Placement
Basic Rules
Tone marks are written on the upper right of the consonant:
| Situation | Position | Example |

| , (Comma) | Used in modern text |

Frequently Asked Questions (FAQ)
Q: The Thai writing order and pronunciation order are different. How do I adapt?
It requires practice and habituation. There are only five pre-vowels (เ แ โ ไ ใ), and their unique shapes make them easy to identify. When you see them, your brain will automatically adjust the reading order. With more reading and practice, you'll quickly get used to it.
Q: Without spaces, how do I know where to segment words?
Rely on vocabulary and linguistic intuition. Just like Chinese doesn't use spaces, you segment sentences by recognizing characters and words. The same applies to Thai – the larger your vocabulary, the easier word segmentation becomes. Beginners can use learning materials with word segmentation markers.
Q: Is Thai handwriting important?
Typing is more important in modern society. However, handwriting helps with memorizing character shapes. Recommendation: Focus on typing, use handwriting as an auxiliary memorization tool, and don't strive for calligraphic perfection.
Q: Why are both Thai and Arabic numerals used?
Historical and practical reasons. Thai numerals are traditional, while Arabic numerals are internationally universal. Modern Thailand uses both – Arabic numerals for daily convenience, and Thai numerals for formal occasions to preserve tradition.
