Mid, high and low class

Learn each letter together with its class: it is the key to reading tones.

Mid class

9 letters

กจฎฏดตบปอ

Live syllables are mid tone, dead ones low. The only class that uses all four tone marks.

Remember them with

ไก่ จิก เด็ก ตาย บน ปาก โอ่งgài jìk dèk dtaai bon bpàak òong

“A chicken pecked a child to death on the rim of a jar”: ก จ ด ต บ ป อ (plus ฎ ฏ, which sound like ด ต)

High class

11 letters

ขฃฉฐถผฝศษสห

Live syllables are rising, dead ones low. Used with ◌่ (low) and ◌้ (falling).

Remember them with

ผี ฝาก ถุง ข้าว สาร ให้ ฉันpǐi fàak tǔng kâao-sǎan hâi chǎn

“A ghost left a bag of rice with me”: ผ ฝ ถ ข ส ห ฉ (plus ฐ ฃ ศ ษ, which share their sounds)

Low class

24 letters

คฅฆงชซฌญฑฒณทธนพฟภมยรลวฬฮ

Live syllables are mid tone; dead ones are high (short vowel) or falling (long vowel). ◌่ gives falling, ◌้ high.

Every letter that is not mid or high is low class: the biggest group, so learn the other two and you know this one too.

See how class, syllable type and tone marks combine in the Thai tone rules chart.

One sound, several letters

These letters sound the same at the start of a syllable. Their class (colour) is what tells them apart.

Sounds at the end of a syllable

As a final consonant, letters collapse into just a few sounds. k, t and p are not released: close your mouth or tongue and stop.

Never used as a final: ฉ ฌ ผ ฝ ห อ ฮ.

Thai consonants FAQ

How many consonants are in the Thai alphabet?

44. Two of them (ฃ and ฅ) are obsolete, so 42 are used today. They spell 21 different consonant sounds, which is why several letters share a sound.

What are the three Thai consonant classes?

Mid (9 letters), high (11) and low (24). The class is part of the spelling system: with the vowel length, the final sound and any tone mark, it tells you the tone of the syllable.

Why does Thai have so many letters for the same sound?

Many come from Sanskrit and Pali, which had sounds Thai doesn’t distinguish any more. The extra letters keep those spellings, and they still matter because letters with the same sound can belong to different classes, like ข (high) and ค (low).

Which Thai consonant is silent?

อ (o ang) has no sound of its own at the start of a syllable: it holds a vowel when a syllable starts with a vowel sound, as in อา (aa). ห is also silent before ง ญ น ม ย ร ล ว, where it makes the syllable follow the high-class tone rules, as in หมา (mǎa, dog).

Do Thai consonants sound different at the end of a word?

Yes. At the end of a syllable most letters fall into a few sounds: k, t, p, m, n, ng, w and y. For example ด, ท and ส all sound like t at the end: ขวด (kùat), บาท (bàat), รส (rót).
