Let’s get started!
Korean has a unique system of referring to siblings that changes depending on relative age and gender. The five ways are:
These are used daily to refer to people outside of your family as well.
For example, you may call an older female classmate “unnie” in some situations, even though you’re not related. Read on to find out more.
Unnie vs. Eonnie
Both mean the same thing, but “eonnie” is the correct spelling according to romanization rules, while “unnie” is another acceptable version. You might also see “oni” and “uni”, which aren’t so common.
For the purpose of this article, we’ll use the word unnie since it’s more common.
What does unnie mean in Korean?
Unnie (언니) means “older sister”, but is only used by women. There are other situations where the word is used.
To emphasize that she’s your own sister, you add “chin (친)” or “woori (우리)” before unnie: chin unnie (친언니) or woori unnie (우리언니).
You can call your oppa or older brother’s wife, “sae unnie (새언니)“, which literally means new unnie. This doesn’t sound mean like it would in English.
Female relatives and cousins
You can call older female relatives such as cousins, “unnie”.
An older female cousin in Korean is “sa-chon unnie (사촌언니)”, but you don’t call her that. Instead, you can call your sa-chon unnie by “name + unnie” or simply “unnie”.
You refer to her as “sa-chon unnie” when speaking with others.
Older female friend or acquaintance
You can also address an older woman in a friendly way by calling her unnie.
- Example: 아는 언니 (Unnie that I know or acquaintance unnie)
There’s a special exception at restaurants or pubs where men over 60 can call female servers unnie, which sounds friendly.
Female upper classmates
If you’re a girl in school, you start calling older females by “name + sunbae (선배 or senior)”, which is gender neutral. After you become more familiar with each other, you can call them by “name + unnie”.
- Example: 효리 선배 → 효리 언니 (Hyori sunbae → Hyori unnie)
Pretty or cool females (mostly celebrities)
If someone is really pretty or cool, girls call them “unnie” as a sign of respect.
- Women like to call older females or sunbae “unnie” as long as they feel comfortable and like each other. Unnie sounds nice, friendly and non-flirty unlike oppa.
(Some women refuse to call male sunbae oppa to completely prevent flirting)
- Female customers call female staff in a clothing store “unnie” whether she’s older or younger. Sometimes customers and staff both call each other unnie. If the age gap is large, female customers refer to staff as “emo (이모 or auntie)” or “sajangnim (사장님)”.
- Unnie is portrayed as a strong or charismatic person in Korean media.
- Jessi, Ra Mi-ran and Kim Sook were called “ssen unnie (쎈 언니 or strong/charismatic unnie)” on Sister’s Slam Dunk (언니들의 슬램덩크).
- With the concept of ssen unnie who help their dongsaeng get a refund (getting a refund is not a given in Korea), Refund Sisters was formed on the variety TV show, Hangout with Yoo.
What’s the cultural background of unnie?
In Korea, sisters fight a lot from teens to early twenties.
They may get along well like best friends, especially if they’re in the same fan club. On the other hand, if their favorite K-pop idol groups are rivals, they’ll fight as well.
Just like all brothers and sisters, the relationship between dongsaeng and unnie is pretty bad during puberty. Unnie is stressed out by their younger sister’s behavior and is quick to yell at her. Dongsaeng dislikes unnie’s commands and meddling, so she fights back.
Unnie and dongsaeng usually argue by saying, “she used my cosmetics/wore my clothes without permission”, “she ate my cake”, etc.
However, sisters argue less and less as they enter adulthood and get closer. Unlike siblings and brothers who become distant during adulthood, unnie and dongsaeng mostly maintain their friendship.
Most of my friends are very happy to have their unnie because they can share many things. (They’re especially ecstatic after both getting married and having kids, since they can share even more.)
What does unnie do for you?
For biological sisters:
Unnie, like hyung, feel a bit pressured to take care of you. They’ll pay for meals and give beauty, life and dating advice. Unnie help you resolve issues if you’re in an unfair situation, or help you get a refund from a store if you’re too shy.
Many unnie influence their younger sisters in terms of fashion style, major, etc. Unnie also take you to cool places like trendy cafes or shopping. It’s nice to have unnie since you can share pretty much everything, including hobbies, attire and perfume.
Although unnie get mad if you use their expensive clothes, purses or shoes without permission, they’ll still love you and don’t tend to beat you up like hyung. But still, unnie can boss you around.
In Korean culture, unnie get married first unless she chooses to be single. If younger sisters or dongsaeng have a wedding before their unnie, it’s considered very inappropriate and almost as a betrayal.
For younger friends:
Having a nice unnie is awesome because they’ll provide a feeling of sisterhood and a lot of good life advice. However, it’s also a double-edged sword that you need to be careful of.
Finding a nice one is very hard. Some easily get jealous of you and backbite. (Not all, but some unnie dislike younger females just because they’re younger as aging is viewed negatively in Korea.) On the other hand, once you get to know kind and loving unnie, they’ll be nice to you unconditionally and you can tell them anything.
What do you do for unnie?
When unnie buys you a meal, you can pay for coffee after. Also, giving them delicious desserts or birthday gifts will help you win their heart.
Once unnie like you, they’ll tell you to talk casually (반말, bahn-mal). It’s easy to make mistakes (being too familiar and disrespectful) when you feel too comfortable. Just make sure to show some respect because if unnie feel like you’re looking down on them or being rude, you might actually lose them.
What’s the difference between Unnie and Noona?
Both Unnie and Noona mean an “older sister” in Korean, but Unnie is used by women and Noona is used by men.
When can I start calling an older female Unnie?
Not when you first meet, but after a few interactions and some rapport is built. It’s a good idea to ask them first as well.
What’s the acceptable age gap to call an older female Unnie?
1-10 years is a good rule of thumb. Some women might not like being called unnie if they’re only a year older than you. When in doubt, ask.
