Park’s research into No’s linguistic-literary experimentation opens a new path for understanding the multilayered diglossia in Chosŏn literature. It also helps us reflect on issues in Korea today, such as Seoul-centrism, social mobility, and wealth and status. I feel that this, the first monographic work on yadam in a Western language, will appeal not only to specialists of premodern Korea, but to a wide range of readers as well.
