What 응 means
It means “yeah,” “yes,” or “okay” in casual Korean.
It answers a question, accepts a request, or acknowledges someone calling you. In conversation, it can also show that you are following along and keep the next turn open.
In casual Korean chat, ㅇㅇ is an even shorter affirmative. As of 2026, the National Institute of Korean Language identifies it as a nonstandard form.
Someone sent me 응—what should I read?
Read a bare 응 as a casual yes unless punctuation changes it.
After a yes/no question or request, it normally agrees; after your name, it acknowledges the call. A question mark changes the reading to “Huh?” or “Could you say that again?” The surrounding message supplies the cue.
Where did 응 come from?
응 is an everyday reply written with ordinary Hangul letters.
The consonant ㅇ has a history linked to the older Hangul letter ㆁ, which represented a nasal sound made with air through the nose. ㆁ appears in Hunminjeongeum, the text that introduced Hangul in 1443; it remained in use into the early 1500s, when it began to merge with ㅇ. A 1933 spelling plan completed the merger.
The name 이응 for ㅇ is recorded in 훈몽자회, a children's textbook for Chinese characters, in 1527. The reply 응 is a native Korean exclamation; the same syllable in 응하다 (“to respond”) comes from a separate Chinese-character root.
Casual yes for close friends, similar-age peers, or younger people; it can sound disrespectful with someone older or unfamiliar.
With an older or unfamiliar person, use the polite 네 instead.

1Why does 응 show as a box on some devices?
Because that device's fonts have no glyph for it. The character is still correct and still copies correctly — the box is a missing glyph, not a broken character.
