Isn't 안녕하십니까 a little formal for "Hi"?
Yes, indeed. So 안녕 is perfect here.
I believe that's more of asking if the person is well. But I agree it's also a formal greeting for Hi.
My non-korean friends used to always say "onion" (°^°)a
Not sure for everyone else but I chose 안녕 and was correct
Yup, I also put it. All the 안녕's are correct.
So I also heard that Hello was 여보세요. Is it not or is it another way to say this?
That's how you say hello on the phone. Just like in Japanese, you say konnichiwa in person but say "moshi moshi?" on the phone
That's more for when you answer the phone.
If you are saying hello in person it is 아녕하세요 but if you are on the phone with someone like on a call you say 여보세요
So this was one of the first things i learned in korean but to be sure isnt this "annyeong" a shorter less fornal version of "annyeonghaseo"
안녕 안녕 나는 지수야 :-)
한자 : 安寧하세요
That's so easy
