1. What is National Thai Language Day?

King Rama IX created Thai Language Day to promote and raise awareness among Thai people of the value and importance of the national language, and to help preserve it in Thailand forever.

In the past, the Thai language was adapted from the Cambodian language. But in 1283, King Ramkhamhaeng decided this was not good enough because the Thai language is tonal. He had an initiative to modify Thai characters for easier writing and to add high and low tone symbols to match with pronunciation in the language. These new characters are adapted from Balinese and Sanskrit languages and have contributed immensely toward the success of the Thai language.

Note that Thai is a language that incorporates new slang from time to time. Currently, there’s popular slang such as “The Vance Kids” which refers to teenagers who like to race motorcycles at night. This term is derived from the sound a motorcycle makes when accelerating.

On National Thai Language Day, to preserve the usage of Thai language and promote proper usage to young people, popular activities held in educational institutes include competitions on essay writing and oral reading competitions to win the scholarships. This is to encourage young people to use the correct forms of sentences and correct pronunciation, especially on the ‘r’ sound and diphthongs.

Today, not only the usage of Thai language is encouraged, but some government officials are also allowed to wear Thai costumes to work. There are also activities to preserve Thai culture, such as an ancient dessert cooking demonstration, Thai folk plays, and Thai dance shows.

4. Composition of the Thai Alphabet

Do you know the composition of the Thai alphabet?

There are forty-four letters, twenty-one vowels, and four consonants. Thai characters are arranged from left to right, with vowels placed in front, above, below, and at the back. Each word is formed by mixing letters like in English, but there are symbols to control the tone of each word in Thai.
