About the Thai Language

Thai is the official language of Thailand and carries deep layers of Pali and Sanskrit vocabulary absorbed through Buddhism, plus a special royal register (rachasap) used when speaking of the monarchy. Everyday politeness is grammatical: men end sentences with the particle khrap and women with kha, which is why greetings sound different depending on who is speaking. Thai belongs to the Kra-Dai family and its closest relative is Lao; the two are largely mutually intelligible in speech, and the Isan variety of northeastern Thailand bridges them. Despite heavy borrowing, Thai is unrelated to Chinese, Khmer or Vietnamese.

The Thai script: How Thai is Written

Thai is written in its own abugida of 44 consonants and numerous vowel signs, traditionally credited to King Ramkhamhaeng in 1283 and derived from the Khmer script, which itself descends from Indian writing systems. There are no spaces between words, no capital letters, and vowel signs can attach above, below, before or after their consonant. Each consonant belongs to one of three classes that help determine a syllable's tone.

Is Thai a Tonal Language?

Yes, Thai is a tonal language with five tones: mid, low, falling, high and rising. The syllable mai, said with different tones, famously yields the sentence mai mai mai mai: new wood does not burn, does it?
