How to Count in Thai
Counting in Thai splits into two things. Reciting numbers is easy — eleven words and two exceptions. Counting things is where it gets interesting, because Thai requires a classifier: a small word that says what kind of object you are counting. This page covers both.
Counting 1 to 10
Start here. Say them aloud; these ten words carry everything else.
| Number | Thai | Pronunciation |
|---|---|---|
| 1 | หนึ่ง | nèung |
| 2 | สอง | sǎawng |
| 3 | สาม | sǎam |
| 4 | สี่ | sìi |
| 5 | ห้า | hâa |
| 6 | หก | hòk |
| 7 | เจ็ด | jèt |
| 8 | แปด | pàet |
| 9 | เก้า | kâao |
| 10 | สิบ | sìp |
Counting past ten
Thai builds numbers the same way English does — largest place value first — but with no irregular words like "eleven" or "twelve". You just say the tens, then the units.
- สิบ (sìp) is ten. 12 is สิบสอง, "ten two".
- Every ten is its digit plus สิบ: 30 is สามสิบ, "three ten".
Two exceptions, and that is the entire irregularity of the system:
| Rule | What changes | Example |
|---|---|---|
| Trailing 1 | หนึ่ง becomes เอ็ด in the units place above ten | 11 = สิบเอ็ด |
| Tens 2 | สอง becomes ยี่ in the tens place | 20 = ยี่สิบ |
Above a hundred, each place value gets its own word. English speakers should pay attention to the last two — there is no English equivalent, and this is where counting large amounts breaks down:
| Value | Thai | Pronunciation |
|---|---|---|
| 100 | ร้อย | róoi |
| 1,000 | พัน | phan |
| 10,000 | หมื่น | mèun |
| 100,000 | แสน | sǎen |
| 1,000,000 | ล้าน | láan |
So 25,000 is not "twenty-five thousand" — it is สองหมื่นห้าพัน, "two หมื่น five พัน". You have to regroup the number as you hear it, which is why prices and rents feel disproportionately hard.
Reciting is the easy half. Recognising a number spoken at speed is the half that needs drilling.
Start drilling →Counting objects: the classifier
Here is the part that surprises learners. In English you say "three dogs". In Thai you cannot just attach a number to a noun — you need a classifier, a word describing the category of thing being counted. The pattern is:
noun + number + classifier
หมาสามตัว — mǎa sǎam tua — "dog three ตัว" = three dogs.
English does this occasionally — "three sheets of paper", "two head of cattle" — but in Thai it is compulsory for every countable noun.
The classifiers worth knowing first
| Classifier | Pronunciation | Used for |
|---|---|---|
| คน | khon | People (except monks and royalty) |
| ตัว | tua | Animals, and items with legs or a body — tables, chairs, shirts |
| อัน | an | Small generic objects. The safe fallback when you do not know the right one |
| ใบ | bai | Containers and flat leaf-like things — bags, plates, tickets, eggs |
| เล่ม | lêm | Books, knives, candles |
| คัน | khan | Vehicles — cars, motorbikes, bicycles |
| ขวด | khùat | Bottles |
| แก้ว | kâew | Glasses of drink |
| ลูก | lûuk | Round things — fruit, balls |
There are dozens more, but these nine cover an enormous amount of daily use. If you are stuck, อัน is understood and mildly wrong rather than incomprehensible — use it and move on.
The "one" exception, again
When counting exactly one of something, the order flips: noun + classifier + หนึ่ง. In casual speech หนึ่ง is often shortened to นึง.
เบียร์ขวดนึง — bia khùat nèung — "one bottle of beer". This is a genuinely useful sentence.
Ordering and asking for things
- How much? เท่าไหร่ (thâo-rài). The answer will be a number, at speed.
- How many? กี่ (gìi) + classifier — กี่คน is "how many people?"
- Baht is บาท (bàat), placed after the number: ห้าสิบบาท, 50 baht.
Ordinal numbers
First, second, third are easy: put ที่ (thîi) in front of the number.
| English | Thai | Pronunciation |
|---|---|---|
| first | ที่หนึ่ง | thîi nèung |
| second | ที่สอง | thîi sǎawng |
| third | ที่สาม | thîi sǎam |
| tenth | ที่สิบ | thîi sìp |
No irregular forms to memorise. Note that here 1 stays หนึ่ง — the เอ็ด rule only applies inside larger numbers.
How to practise counting
- Get 1–10 automatic first. Everything else assembles from them, so hesitation here slows down every larger number.
- Then randomise. Counting in order trains a sequence. If you can only reach 57 by running up from 50, you have not learned 57.
- Add classifiers separately. Learn the numbers cold first, then layer the classifiers on. Doing both at once is where people stall.
- Practise listening hardest. Counting aloud is comfortable. Catching a number someone else says is the skill that actually gets used.
Randomised, audio-first, and weighted towards whatever you keep missing.

How do you count from 1 to 10 in Thai?
หนึ่ง สอง สาม สี่ ห้า หก เจ็ด แปด เก้า สิบ - nèung, sǎawng, sǎam, sìi, hâa, hòk, jèt, pàet, kâao, sìp. These ten words build every other number in the language.
What is a Thai classifier?
A word that indicates the category of the thing being counted. Thai requires it when counting objects: noun, then number, then classifier. หมาสามตัว is literally "dog three tua" and means three dogs.
Which Thai classifier should I use if I do not know?
อัน (an) is the general-purpose one for small objects and is widely understood. It is better to use it and be slightly wrong than to leave the classifier out.
Why does the word order change when counting one thing?
For exactly one, Thai puts the classifier before the number: noun, classifier, then หนึ่ง, often shortened to นึง in speech. So one bottle of beer is เบียร์ขวดนึง.
How do you say ordinal numbers in Thai?
Put ที่ (thîi) in front of the number. First is ที่หนึ่ง, second is ที่สอง. There are no irregular forms.
Is counting in Thai difficult?
The number system itself is one of the easiest parts of Thai, with only two exceptions across the whole range. The harder parts are the classifiers when counting objects, and recognising numbers spoken at natural speed.
