When to use formal vs informal in spoken Korean (나는 vs 저는) 안녕하세요 여러분 !! I understand when to use informal/formal in other languages (french and spanish) because it is simpler, but for Korean informal/formal along with honorifics confuse me. Can someone please explain if I were to introduce myself, when would I use 나는 vs 저는? Thank you in advance! 감사합니다 !!
