Travel Tips

Asaragu??? I don't think that means anything. Mi ahn hae yo --- is I'm sorry the informal way. Korean is a pretty difficult language if you didn't grow up around it -- I did, but you can probably get a software program like Rosetta Stone, but you have to be really devoted to learn it. Source(s): I'm korean lol

'Mi an hae' it the informal way to say sorry. If you put the 'yo' in the end of sentence, it turns to a bit more formal expression.

And..I can't not make any sense with "Asaragu";; Sorry;;
Can you try to explain the context??
MI AN HAE
Thats not a word though. Write it in korean or something.
Me on hey yo is I am sorry in the informal. Me on ham ni da is a little more formal.
