Ryun is a name of Korean origin, derived from the Korean word "ryu" which means "flowing". The name Ryun is believed to have been popularized by Korean novelist Kim Yideum in her novel "Ryun's Story", published in 1936. In this novel, the protagonist Ryun is a strong-willed and independent woman who defies societal norms and expectations. As such, the name Ryun has become associated with independence, strength of character, and nonconformity in Korean culture. While it is not one of the most common names in Korea, Ryun has gained popularity among parents looking for unique and meaningful names for their children.
"The name Ryun saw a significant rise in popularity between 1991 and 1996, with over 10 births each year during that period. However, it has since declined, with fewer than 7 births annually from 2001 onwards. Overall, there have been 182 babies named Ryun born between 1972 and 2013."
