안녕하세요 (Annyeonghaseyo)
This is a polite and formal way to say good morning and can be used in most situations.
There are other ways to say good morning in Korean, depending on the context and the level of formality:
* 안녕 (Annyeong) - This is a more casual and informal way to say hello or good morning.
* 좋은 아침 (Joheun achim) - This translates to "Good morning" and is more formal than "안녕하세요".
Important Note: Korean language uses honorifics, which are polite expressions that reflect the speaker's respect for the listener. "안녕하세요" is the most polite and formal greeting, while "안녕" is more casual. You should use "안녕하세요" when speaking to someone older than you, someone you don't know well, or someone in a position of authority.
