Thai Classifiers: How to Count People, Animals and Things

To count something in Thai, you need a classifier: a small word placed after the number, chosen according to the kind of thing you count. The order is always noun + number + classifier: “two cats” is แมวสองตัว mɛɛo sɔ̌ɔng dtua, literally “cat two body”. Learn about twenty classifiers and the four patterns below, and you can count, order and point at almost anything.

Thai grammarians call them ลักษณนาม lák-sà-nà-naam. English has a faint echo of the idea in “two cups of coffee” or “three sheets of paper”, but in Thai the classifier is not optional and it applies to every countable noun, including people and animals.

The basic rule: noun + number + classifier

The noun comes first, then the number, then the classifier. Nothing else moves:

นักเรียนสามคน nák-rian sǎam kon: three students (student three person)

เสื้อสองตัว sʉ̂a sɔ̌ɔng dtua: two shirts (shirt two body)

หนังสือห้าเล่ม nǎng-sʉ̌ʉ hâa lêm: five books (book five volume)

You cannot say สองแมว sɔ̌ɔng mɛɛo for “two cats”: it sounds as wrong to a Thai ear as “cat two” does in English. If you need a refresher on the numbers themselves, see our guide to Thai numbers from 1 to 1,000,000.

An adjective stays glued to the noun, before the number: เสื้อแดงสองตัว sʉ̂a dɛɛng sɔ̌ɔng dtua, “two red shirts”. And when you are not counting at all, you do not need a classifier: ผมมีแมว pǒm mii mɛɛo simply means “I have a cat” (or cats).

Why does Thai have classifiers?

Thai nouns have no plural and no article. แมว mɛɛo can mean “a cat”, “the cat” or “cats”. The classifier is what makes a noun countable and specific: it turns the general idea “cat” into a number of individual cats, or into “this cat” or “that cat”.

The choice of classifier also tells you something about the object: its shape (long, flat, round), its function (vehicle, machine) or its status (person, monk). This is why many classifiers are ordinary nouns used in a second role: ลูก lûuk is “child” but classifies round things, หลัง lǎng is “back” but classifies houses, คัน kan is a handle or shaft and classifies vehicles.

The 20 most useful Thai classifiers

People and animals

Monks are never counted with คน kon. Use รูป rûup in everyday speech; องค์ ong is more reverent and is also used for Buddha images and members of the royal family. You will see monks counted this way in the story Morning alms. In restaurants and hotels, staff use ท่าน tân for customers out of politeness.

Everyday objects

ตัว dtua (“body”) covers animals, clothes and anything with “legs” such as tables and chairs. ใบ bai (“leaf”) covers flat or hollow things you can hold: bags, tickets, hats, banknotes, but also an empty glass or plate as an object.

Food and drink

Here the classifier is often the container itself: two glasses of coffee, three bottles of water. Note the difference between the drink and the object: กาแฟสองแก้ว gaa-fɛɛ sɔ̌ɔng gɛ̂ɛo is “two coffees”, but แก้วสองใบ gɛ̂ɛo sɔ̌ɔng bai is “two (empty) glasses”. The same goes for จาน jaan: ข้าวสองจาน kâao sɔ̌ɔng jaan is two plates of rice, จานสองใบ jaan sɔ̌ɔng bai is two plates.

For fruit, ลูก lûuk is what you will hear at the market; ผล pǒn belongs to written and formal Thai.

Vehicles, buildings and nature

Some nouns are their own classifier: คน kon (คนสามคน, three people), ห้อง hɔ̂ng (ห้องสองห้อง, two rooms), คำ kam (คำนี้, this word). Units of time and measure need no classifier at all: สามวัน sǎam wan (three days), สองชั่วโมง sɔ̌ɔng chûa-moong (two hours), ห้าสิบบาท hâa-sìp bàat (fifty baht), สองกิโล sɔ̌ɔng gì-loo (two kilos).

“One” goes after the classifier (usually)

With หนึ่ง nʉ̀ng, “one”, Thai has two orders, and both are correct:

• noun + classifier + หนึ่ง: แมวตัวหนึ่ง mɛɛo dtua nʉ̀ng. This is the most natural form. It often works like the English article “a”: “a cat, a certain cat”. Descriptions often begin this way: มีแมวตัวหนึ่ง… mii mɛɛo dtua nʉ̀ng…, “there was a cat…”.
• noun + หนึ่ง + classifier: แมวหนึ่งตัว mɛɛo nʉ̀ng dtua. This follows the normal counting order and stresses the quantity: one cat, not two. You hear it when listing quantities or ordering.

In everyday speech, หนึ่ง after the classifier is said quickly, often with a mid tone, nʉng, and is sometimes written นึง in chat messages. At a coffee stall, ขอกาแฟเย็นแก้วหนึ่ง kɔ̌ɔ gaa-fɛɛ yen gɛ̂ɛo nʉ̀ng and ขอกาแฟเย็นหนึ่งแก้ว kɔ̌ɔ gaa-fɛɛ yen nʉ̀ng gɛ̂ɛo both get you one iced coffee.

To say “only one”, use the classifier + เดียว diao: แมวตัวเดียว mɛɛo dtua diao, “just one cat”. For “another one”, put อีก ìik before the number: ขออีกแก้วหนึ่ง kɔ̌ɔ ìik gɛ̂ɛo nʉ̀ng, “one more glass, please”.

This one, that one: classifier + นี้ / นั้น

To say “this cat” or “that shirt”, Thai also uses the classifier: noun + classifier + นี้ / นั้น / โน้น.

Do not confuse นี้ níi (high tone, “this” after a classifier) with นี่ nîi (falling tone, “this is…, here is…” at the start of a sentence): นี่คือแมว nîi kʉʉ mɛɛo, “this is a cat”.

In a shop, the noun disappears and the classifier does all the work:

เสื้อตัวนี้เท่าไหร่ครับ sʉ̂a dtua níi tâo-rài kráp? How much is this shirt?

เอาตัวนี้ค่ะ ao dtua níi kâ. I’ll take this one.

เอาตัวสีแดง ao dtua sǐi dɛɛng. I’ll take the red one.

This is exactly how Hugo shops in the story Shopping for a shirt: once the seller knows you are talking about shirts, ตัวนี้ dtua níi is enough. The same pattern singles out one item among several: บ้านหลังใหญ่ bâan lǎng yài, “the big house”.

How many? Asking with กี่

To ask “how many”, put กี่ gìi in place of the number: noun + กี่ + classifier.

The answer reuses the classifier, usually without the noun: สองตัว sɔ̌ɔng dtua, สามคน sǎam kon. At the fish market, a seller will ask กี่ตัว gìi dtua when you point at the fish, and you answer with a number + ตัว. You can watch Yai buy her fish and squid in the story The fish market. For other question words, see our guide to Thai question words.

Classifiers also follow ทุก túk (“every”) and หลาย lǎai (“several, many”): ทุกคน túk-kon (everyone), หลายตัว lǎai dtua (several animals or shirts). For ordinals, add ที่ tîi before the number: คนที่สอง kon tîi sɔ̌ɔng, “the second person”.

What to say when you don’t know the classifier

Thai has dozens of classifiers, and even native speakers hesitate over the rare ones. When you are not sure:

1. Objects: use อัน an. It is the general-purpose classifier for things, and Thais use it themselves in casual speech. ขอสองอัน kɔ̌ɔ sɔ̌ɔng an, “two of those, please”, works at any snack stall.
2. People: always คน kon (except monks). Animals: always ตัว dtua. These two never fail.
3. Food and drink: name the container. แก้ว, จาน, ชาม, ขวด: if it comes in a glass, a plate, a bowl or a bottle, that is your classifier.
4. Point and say อันนี้ an níi, “this one”. It is understood everywhere.
5. Listen to the answer. If you say หนังสือสองอัน nǎng-sʉ̌ʉ sɔ̌ɔng an, the seller may reply สองเล่มนะครับ sɔ̌ɔng lêm ná kráp, giving you the right word for free.

Never use อัน for people or animals: it would sound like you are talking about objects.

How to learn Thai classifiers

• Learn each noun with its classifier, the way learners of French or German learn the gender of each noun: แมว (ตัว), หนังสือ (เล่ม), รถ (คัน). Writing them as a pair in your flashcards saves you from relearning later.
• Start with the big six: คน, ตัว, อัน, ใบ, แก้ว, จาน. They cover most of what you will count in your first months in Thailand.
• Meet them in real sentences. Classifiers stick when you hear them in a scene: bags at the night market, eggs at breakfast, fish at the market. In the Kru May stories, classifiers appear in context, a small grammar badge explains the pattern where it first appears, and every word can be tapped to hear it.
