Tone rules at a glance

The actual tone of a syllable is determined by three factors: consonant class, vowel length, and tone mark. This table shows the resulting tone for live syllables (ending in a long vowel or sonorant).

Class No mark ่ (mai eek) ้ (mai tho) ๊ (mai dtri) ๋ (mai jàtdtawa)
Mid Mid Low Falling High Rising
High Rising Low Falling
Low Mid Falling High Rising

Dead syllables (short vowel + stop final, or stop final alone) follow different rules. The full tone system becomes clear once you know the consonant classes — see the Alphabet page.

💡
Thai has no verb conjugation. Instead of changing verb forms for past/present/future, Thai uses time words (เมื่อวาน yesterday, ตอนนี้ now, พรุ่งนี้ tomorrow) and aspect particles (แล้ว completed, กำลัง ongoing, จะ will). Tones carry the grammatical weight that other languages put on inflection.
