Nunchi, sometimes spelled “noonchi,” is a Korean concept signifying the subtle art and ability to listen and gauge others’ moods. In Western culture, it is roughly equivalent to emotional intelligence. It’s the skill of reading a room, sensing what others are thinking and feeling, and reacting appropriately.
The term derives from the Korean words “nun” (eye) and “chi” (measure), so it translates roughly to “eye measure.” People with good nunchi are able to understand and respond to others without needing many words. They pick up on subtle cues, are adept at building rapport with others, and often act in a considerate and appropriate manner according to the situation. Lack of nunchi might lead to social awkwardness or misinterpretation of people’s feelings or intentions.
In Korean society, nunchi is considered an essential social skill, affecting personal relationships, business interactions, and more.
