How to say hello in korea?

Formal: 鞎堧厱頃橃劯鞖?Ahn-nyung-ha-se-yo
Informal: 鞎堧厱 Ahn-nyung (also used to say 'bye')

hard to spell in english but let me write it the way you say it

un-young-ha-say-yo

Formal- Annyong ha saeyo- To your boss, or anyone that is older than you/or anyone you are meeting for the first time. A bow is included.

Informal- Annyong- To your friends or people younger than you. No bow for that

Hello on the telephone- Yeob sae yo

This is all the perfect pronounciation of the words in English spelling.

it sounds more like
annyo haseyo

aneyasayo

annyoung ha seh yo 鞎堧厱!

Anneonghasaeyo!
You say anneonghasaeyo to greet people or when you meet someone and you bow to that person..
On the oether hand, if you're talking over the phone, you'regoing to greet him/her Yobosaeyo!

ahn young (informal)
ahn young ha sae yo (formal)

it is pronounced like this.
"i-want-to-go-back-to-america"

"Annyeong!" - "Hi!" Pretty informal
"Annyeong haseyo" - Regular hello
"Annyeong hashimnika" - More formal greeting

- You would usually do a small bow when saying hello. A bend of the neck, or a shallow bend at the waist is usually sufficient. If you do too deep of a bow, it can seem insulting (unless you're meeting the President, or something).


"Pan gap sumnida" - Nice to meet you

- If you shake someone's hand upon meeting them, support your right arm with your left hand under the elbow. It's polite to use both hands when giving something to someone.


"Go map sumnida" - Thanks
"Kamsa hamnida" - More formal thank you.


A bit more than you asked for, but hope that helped!

Anyounghaseyo :)
