The origin of the Thai writing system can be traced back to the Devanagari script of India, which was also utilized for writing the Pali and Sanskrit languages. Thus, the Thai script has its roots in India but underwent modifications as it journeyed through Cambodia before reaching the Thai people. This script, tailored to the Thai language, first emerged in the year 1283, thanks to the efforts of King Ramkhaeng of Sukhothai. While the shapes of the characters have undergone some changes over the centuries, the fundamental system remains consistent with its 13th-century counterpart. The Thai alphabet consists of 44 consonants. Vowels are not included in the alphabet but are listed below. Consonants are divided into three classes: Low, Middle, and High, which define the tone and pronunciation of the syllable.
