The many faces of 아이고

Cultural note
아이고 is one of the most distinctly Korean sounds you'll encounter. It crosses generations — young people say it, old people say it, and it means something slightly different each time.
You'll also hear the shorter 아이구 and 어이구, which are soft variations of the same word. And 아고, used more by older speakers in some regions.
The reason 아이고 is worth learning early is simple: when something happens — something surprising, painful, sweet, or sad — this is the sound Koreans make. Learning it means understanding what's happening in the room even before you understand the words.
