Aigoo (아이고, officially romanized aigo) is a Korean exclamation that works like "oh my," "oh dear," or "ugh." It has no literal meaning. Koreans say it to express tiredness, frustration, surprise, sympathy, or even affection, and the tone of voice tells you which one.
Word at a glance
아이고aigo
- Literally
- no literal meaning (a sound of emotion)
- In natural English
- Oh my! / Oh dear! / Ugh...
A sound, not a word
아이고 is an interjection, a sound people make when a feeling spills out. That is why it is hard to translate: depending on the moment, it can be a sigh, a gasp, or a warm "aww."
If you watch K-dramas, you will hear it constantly, especially from parents and grandparents. Younger people use it too, sometimes with a self-aware, slightly comic tone.
5 feelings aigoo can express
- Tiredness or pain: sitting down after a long day, or a sore back
- Frustration: when something goes wrong, like "ugh, seriously"
- Surprise: being startled by someone or something
- Sympathy: reacting to someone else's bad news, like "oh no, poor thing"
- Affection: grandparents greeting a grandchild with a warm "aww"

Aigu, eoigu and other versions
You will hear several variations. 아이구 (aigu) is a softer, slightly more casual version, and many fans write it as "aigoo" because of this pronunciation. 어이구 (eoigu) often carries a mix of disbelief and mild scolding, like "oh, come on."
Stretching it out, as in "아이고~," adds drama. A long, falling "aigooo" sounds exhausted or sad, while a short, bright "aigo!" sounds surprised.
어이구, 또 늦었어?
Eoigu, tto neujeosseo?
Oh come on, you're late again?
When not to use aigoo
Aigoo is fine in everyday life, but sighing it at your boss after receiving a task can sound like a complaint. Traditionally, 아이고 was also part of mourning cries at funerals, so its sad, drawn-out form can carry real grief. Match your tone to the situation.
How to pronounce aigoo
Say it in three syllables: "ah-ee-go." In relaxed speech the last syllable often moves toward "goo," which gives us the popular spelling "aigoo." Let the pitch follow the feeling: falling for tired, rising for surprised.
