In Korean, "sister" is said as "언니" (eonni) when referring to an older sister and "여동생" (yeodongsaeng) for a younger sister. "Brother" is "형" (hyeong) when referring to an older brother and "남동생" (namdongsaeng) for a younger brother. These terms reflect the importance of age hierarchy in Korean culture.
"Nuna" in Korean is an informal term used by males to address an older sister or a female friend who is older than them. It's a term of endearment and respect.
it means older sister IF you are a boy. but if you are a girl, it is UNNIE.
"Unnie" is written in Korean as "언니." It is a term used by females to refer to an older sister or a close older female friend. The pronunciation is similar to "un-nee."
It depends on your gender. If you're a girl, your older sister/an older female is your "unnie" (uh-nee) If you're a guy, your older sister/ an older female is your "noona" (noo-na) A younger brother or sister is your "dongsaeng" (dong-seng) Dongsaeng is used regardless of your gender or the person's gender.
If u mean how is it spelled in Korean, it's 여동생. 동생 means little brother (see there's no "여" which pretty much means female), but is often also used as little sibling. So the older brother would say that so and so is my 동생, regardless of the gender.
Unni is used when referring to a slightly older woman or older sister by a female speaker.
