Young-ja, also spelled Yeong-ja, is a Korean feminine given name.
According to South Korean government data, it was the most popular name for baby girls born in 1940.
[2][3] The syllable "ja" is generally written using a hanja literally meaning "child" (子; 아들 자; adeul ja).
In Japan, where this character is read ko, it was originally used as suffix for the names of girls in the aristocracy.
The practice of adding -ko to girls' names spread to the lower classes following the 1868 Meiji Restoration.
