During the discussion, His Majesty urged people, educational institutions, and public and private organizations to be aware of the proper use of the Thai language. His participation in the discussion reflected his interest in the preservation of Thai cultural heritage. He also gave advice on the preservation of the language. He emphasized the importance of using correct pronunciations and local dialects. Those who want to create new words must know the language very well. To recognize His Majesty’s concern for the proper use of the Thai language, the National Thai Language Day has been observed since 1999.
