How many tones does Thai have?

Five — mid, low, falling, high, and rising. Every spoken Thai syllable carries exactly one of them.

What are the four Thai tone marks?

ไม้เอก, ไม้โท, ไม้ตรี, and ไม้จัตวา, written above the first consonant. They modify a syllable's tone — but a mark doesn't always produce the tone of the same name; the result also depends on the consonant's class.

Does a tone mark always give the tone it's named after?

No. ไม้เอก (mai ek) produces a low tone on a mid- or high-class consonant, but a falling tone on a low-class one. The consonant class decides the outcome together with the mark.

What's the difference between a live and a dead syllable?

A live syllable ends in a sound you can hold — a long vowel or an m/n/ng/y/w ending. A dead syllable ends abruptly — a short vowel or a p/t/k stop. When there's no tone mark, this live/dead distinction changes the tone.

Do I need to read Thai script to learn the tones?

You can hear and copy the five tones without it. But to predict a written word's tone you need the script, because the tone is encoded in the spelling — the consonant's class, the vowel, the syllable type, and any tone mark.

The Thai script

Thai tones.

Five tones, one syllable apart. See each one’s pitch contour and hear it in a real voice — then learn the rules that tell you which tone any Thai syllable takes.

Thai is a tonal language: the same string of consonants and vowels means different things depending on the pitch your voice traces across it. There are five tones, and every spoken syllable carries exactly one. The good news is that the tone of a written word is almost always predictable from its spelling — once you know three things: the class of its first consonant, whether the syllable is “live” or “dead,” and which tone mark (if any) sits above it. Start by hearing the five, then learn the rules.

Meet the tones

Mid

สามัญ

มา“come”

Stays level — the flat one. Just a small dip at the very end.

— no recording yet

Low

เอก

ไข่“egg”

Starts low and sinks lower. A quiet downward drift, never flat.

— no recording yet

Falling

โท

ไม่“not”

Lifts, then drops — and the turn comes early. The fall is the story.

High

ตรี

ม้า“horse”

Climbs to a peak that lands late. Still rising near the end — not a flat high note.

Rising

จัตวา

หมา“dog”

Dips down first, then sweeps up. A smooth U.

The four tone marks

Marks are called วรรณยุกต์(wannayúk) and sit above the first consonant. A mark does not always produce the tone of the same name — the result also depends on the consonant’s class.

Mark	Name	Written	Low class	Mid class	High class
่	ไม้เอกmái èek	ก่	Falling	Low	Low
้	ไม้โทmái thoo	ก้	High	Falling	Falling
๊	ไม้ตรีmái trii	ก๊	—	High	—
๋	ไม้จัตวาmái jàttawaa	ก๋	—	Rising	—

ไม้ตรี and ไม้จัตวา appear only on mid-class consonants in practice. When a mark is present, the tone is never mid, and live/dead status no longer matters.

Live & dead syllables

When there’s no tone mark, the tone depends on whether the syllable is live or dead. Live:ends in a sound you can hold — a long vowel, or a sonorant final (the m / n / ng / y / w sounds); it can be sustained. Dead:ends abruptly — a short vowel with no final, or a stop final (the p / t / k sounds); it stops short. One extra wrinkle: for a low-class consonant, a dead syllable’s tone also depends on vowel length (short vs long). For mid- and high-class consonants, vowel length doesn’t change a dead syllable’s tone.

The tone rules

No tone mark

Class	Live	Dead + short	Dead + long
Low class	Mid	High	Falling
Mid class	Mid	Low	Low
High class	Rising	Low	Low

Mnemonic: mid-class consonants “bridge” the other two — in live syllables they behave like low-class (→ mid), in dead syllables like high-class (→ low).

Minimal pairs

Same syllable, different tones, different meanings. The classic five-tone คา set carries all five at once.

The คา set — five tones, one syllable

คา	khaa	Mid	to be stuck / lodged
ข่า	khàa	Low	galangal (the root)
ขา	khǎa	Rising	leg
ค่า	khâa	Falling	value, cost
ค้า	kháa	High	to trade

The มา trio

หมา	mǎa	Rising	dog
มา	maa	Mid	to come
ม้า	máa	High	horse

ไม้ใหม่ไม่ไหม้ไหม
“new wood doesn’t burn, does it?” — five tones in one breath
