The text is used for studying Pali language. It was written in Nissaya style, which is Pali word first and followed by Lao word as translation word by word. This study was running at the monastic schools and later in the Pali schools in Laos during the 20th century. Nowaday, it is taught in Buddhist schools and universities.
