Short but powerful! It's not just 'Yes', but also a filler meaning 'I'm listening' or 'I understand'. You'll often see Koreans repeating 'Ne... ne...' while on the phone.

A polite 'No'. Use it when correcting facts. However, refusing an offer with just 'Aniyo!' can sound too cold. It's better to use 'Gwaen-chan-a-yo' (No thanks) for refusals.

The best reaction when agreeing with someone. Reactions are huge in Korean conversation. Nod your head and say 'Ma-ja-yo!' brightly to build instant rapport.

The ultimate vague word. Use it when you can't answer or want to politely say no without saying 'No'. If a Korean says 'Geulsseyo...', take the hint: it usually means 'No'.

The happiest way to agree. If someone asks 'Want to eat Galbi?', answering 'Jo-a-yo!' sounds much more enthusiastic and friendly than just 'Ne'.

Use this when locals ask you directions or questions and you genuinely don't know. A slight shrug makes it natural. (Note: Use a different phrase for 'I don't understand'.)
