“Historically, the Thai language is primarily rooted in the Tai-Kadai language family, with some adaptations over time, especially in basic vocabulary used for common or general concepts. Some Thai words were influenced by the Khmer language, and others were borrowed from languages such as Pali and Sanskrit,” according to Assistant Professor Dr. Kiat Thepchuaysuk, Director of the Center for Thai as a Foreign Language (CTFL), Chulalongkorn University.
