The Thai Language：Useful Words and Phrases

As the official language of Thailand, Thai is spoken by more than 20 million people in Thailand. It is a member of the Tai language family, with plenty of words borrowed from Old Khmer, Pali, and Sanskrit. It is a tonal language, and spoken Thai is mutually intelligible with Laotian.

The script of Thai derives from the Khmer language and is closely related to Laotian. It has a complex orthography, with silent letters used to keep the traditional spelling and many letters with the same sound. There are several different ways to transcribe Thai using the Latin alphabet, and their main weakness is the lack of tonal indication. The first Thai inscriptions date back to 1292 CE.

Dialects of the Thai Language

There are four major dialects of the Thai language in Thailand: southern, northern ("Yuan"), northeastern (close to Lao language), and central.

The central regions’ Thai dialect is called Central Thai or Bangkok Thai. Central Thai is the most widely used dialect around the whole country. All schools in Thailand teach in central Thai. Most video media and paper books are in Central Thai.

Besides the major four dialects, there are some ethnic group dialects in Thailand, such as Phuan and Lue. They are spoken by just small populations in Thailand.

Writing Thai

The Thai script is believed to be derived from the Khmer script (Cambodia’s official language script). Thai is written from left to right. Different from English, written Thai has no spaces to separate words. You can often see a block of text on a page, with little spacing/punctuation.

It is believed that more than half of Thai vocabulary, grammar, intonation, and vowels are common with the Lao language. Thai script is so close to the Lao script that most literate Lao can understand written Thai.
