"Korean alphabet. For over a millennium, Korean was written with adapted Chinese characters called hanja, complemented by phonetic systems like hyangchal, gugyeol, and idu. In the 15th century, a national writing system called hangul was commissioned by Sejong the Great, but it only came into widespread use in the 20th century, because of the yangban aristocracy's preference for hanja."
In this lesson, we will take a look at how to say "good night" in Korean. The most common way is to say jaljayo (in Hangul: 잘자요). Just like any language, the Korean language has numerous words and phrases for saying farewell to someone.
