Les 44 consonnes thaïlandaises
Grammar Rule in 30 Seconds
Thai uses 44 consonants categorized into three classes that determine the tone of every word you speak.
- Every consonant has a name based on an object, like ก (Kor Kai - Chicken).
- Consonants are split into High, Mid, and Low classes for tone rules.
- Some consonants change their sound when they move from the start to the end of a syllable.
