Unnie (언니, officially romanized eonni) means "older sister" in Korean, and only girls and women use it. Beyond family, Koreans use unnie for any older woman they feel close to, such as a friend, a coworker, or a favorite idol. Men say noona (누나) instead.

Unnie means older sister, from a girl's point of view
Korean family words change depending on who is speaking. A younger sister calls her older sister 언니 (eonni), while a younger brother calls the same person 누나 (nuna, usually spelled noona). There is no single word for "sister" that everyone uses the way English does.
Most English-speaking fans spell it "unnie" because it matches the sound better than the official romanization "eonni." Both refer to exactly the same word.
우리 언니는 회사원이에요.
Uri eonnineun hoesawonieyo.
My older sister is an office worker.
언니가 둘 있어요.
Eonniga dul isseoyo.
I have two older sisters.
Unnie outside the family
Koreans rarely call older people by their first name alone, so family words fill that gap. Once a woman feels close to an older woman, she will usually switch from her name or a formal title to 언니. Calling someone unnie signals warmth, trust, and a little bit of "I look up to you."
You will hear it between friends a year or two apart, between coworkers who have become close, and from fans talking about female idols and actresses they admire.
- Friends: an older friend, even by just one school year
- Work: a close senior colleague, usually once you are on friendly terms
- Fandom: female fans calling an older female idol unnie
- Shops and restaurants: some women call female staff unnie in a casual, friendly way
언니, 이거 같이 먹을래요?
Eonni, igeo gachi meogeullaeyo?
Unnie, do you want to share this with me?
언니라고 불러도 돼요?
Eonnirago bulleodo dwaeyo?
Can I call you unnie?
How to use unnie with a name
To be specific, put the person's first name in front: 수아 언니 (Sua eonni), "Sua unnie." Koreans do this naturally in conversation and in group chats.
Asking "Can I call you unnie?" is a common, sweet moment in Korean friendships and dramas. It marks the point where a relationship moves from polite to close.
수아 언니 진짜 친절해요.
Sua eonni jinjja chinjeolhaeyo.
Sua unnie is really kind.
Unnie vs noona vs oppa vs hyung
Korean has four words for older siblings, and the right one depends on two things: your own gender and the gender of the older person.
- Female speaker to an older female: 언니 (eonni / unnie)
- Male speaker to an older female: 누나 (nuna / noona)
- Female speaker to an older male: 오빠 (oppa)
- Male speaker to an older male: 형 (hyeong / hyung)
How to pronounce unnie
Say it as two syllables: "uhn-nee." The first vowel ㅓ is like the "u" in "fun," not the "oo" in "moon," which is why fans landed on the spelling "unnie." Hold the double ㄴ slightly so you hear both n sounds.
Questions people ask
Can a guy say unnie?+
Not in the normal sense. A man calls an older woman noona (누나). Men do sometimes say unnie as a joke, or in specific workplaces where it has become a general way to address women, but it is not standard.
Is it rude to call a stranger unnie?+
It is casual rather than rude. Between women it often feels friendly, but some people prefer more polite terms with strangers. When in doubt, use 저기요 (jeogiyo, "excuse me").
What is the difference between unnie and eonni?+
None. Eonni is the official Revised Romanization of 언니, and unnie is the popular fan spelling that matches the pronunciation.
How do you reply when someone calls you unnie?+
Usually you just answer naturally. If someone asks to call you unnie, a warm 그럼! (geureom, "Of course!") is the classic reply.
