Thai script is the writing system used for the Thai language, which is the official language of Thailand. It consists of 44 consonants, 15 vowel symbols, and various tone markers. The script is an abugida, meaning that each character represents a consonant with an inherent vowel sound that can be modified with diacritics. Developed in the 13th century by King Ramkhamhaeng, Thai script is derived from the Brahmi script and has evolved over time. It is written from left to right and does not use spaces between words, making it unique compared to many other writing systems.
