There are five different speech styles in Korean, but only three of them are commonly used in everyday Korean. 1) formal and polite (ends with ㅂ니다) 안녕하십니까, 저는 리리입니다. 2) informl and polite (ends with 요) 안녕하세요, 저는 리리예요. 3) informl and not polite 안녕, 난 리리야. \^o^/

English is more informal than Korean. You can just say: "Hello, my name is _____". If you are meeting someone really informally (someone your age, at school, a person on the street, etc.) you could say "Hi! I'm _______". Either would be okay in almost any situation :) Hope this helps!

1) formal and polite (ends with ㅂ니다) 안녕하십니까, 저는 (Your name)입니다. 2) informal and polite (ends with 요) 안녕하세요, 저는 (Your name)예요. 3) informal and not polite 안녕, 난 (Your name)야. 4) 안녕하세요, (Your name)이라고 합니다. There are many ways to introduce yourself in Korean. Read this- https://koreanly.com/how-to-introduce-yourself-in-korean/ korean introduction

There could be two ways of introducing yourself in Korean, the first one, the more common, sort of English type of introducing yourself, similar to "Hello, I am ______ / Hello, my name is _____.", while the second one, a less common but more natural, probably more Korean way of saying it, which is kind of hard to translate literally into English. First: 안녕하세요, 저는 이수영입니다. ~ Hello, I am Soo-young Lee. 안녕하세요, 제 이름은 이수영입니다. ~ Hello, my name is Soo-young Lee. Second: 안녕하세요, 이수영이라고 합니다. ~ Hello, I am Soo-young Lee. 굿럭^^

Hola, mi nombre es Lily. LOL jk Hello, my name is Lily -> 안녕하세요, 제 이름은 릴리입니다. (formal) 안녕, 내 이름은 릴리야 (informal)
