What Does “Unnie” Mean in Korean

Key Takeaways

• “Unnie” (언니) means “older sister” when spoken by a female to an older female, but it can also imply friendship and closeness.
• Honorifics, such as “unnie,” are terms used to address someone respectfully in Korean, demonstrating politeness and social awareness.
• The term "unnie" is gender-specific, meaning it can only be used by women, for women. Men use "noona" to refer to an older female. 
• Understanding the differences between “unnie,” “oppa,” “noona,” and “hyung” helps you communicate clearly and prevent cultural misunderstandings in Korean.

Watch a lot of K-drama or listen to K-pop? Join the club. As you consume your favorite media, you’ve probably heard your fair share of “unnie.” But what does unnie mean in Korean? Translating to “older sister,” the term is an honorific, so it carries cultural weight and reflects how relationships are perceived in Korean culture. And understanding Korean honorifics is crucial to learning this beautiful language.

Politeness is necessary in all languages. However, as you start to learn basic Korean, you’ll find that it goes beyond 'pleases' and 'thank yous.' Honorifics are a way to address someone, signifying good manners, social hierarchy, intimacy, and respect, which helps you build and maintain relationships. 

Since your age and social status directly influence the way you speak to other people in Korean, using the right honorific shows that you're culturally aware. When we refer to someone as "unnie" as an honorific, using it correctly is a sign of respect and a polite way to express emotional closeness to the person you're speaking to.  

What Does “Unnie” Mean in Korean?

So, what does unnie mean in Korean? In its literal translation, unnie (언니) means “older sister” (just with a few sneaky caveats). In Korea, only females can use the term "unnie." Men, on the other hand, should use "noona." Secondly, when a female says it, it doesn't have to be directed only towards her older sister—you can use it to refer to close friends, other family members, or even admiration of your favorite older female celeb.

Once you learn the Korean language, you might use unnie when you talk to: 

• An older sister.
• An older female friend.
• An older female colleague you’re close to.
• An older waitress at a cafe.
• Your friends or fellow fans when you’re stanning your favorite female idol.

Here’s an example of a female talking to her old female coworker:

•  지영 언니, 오늘 같이 점심 먹을래요? (Jiyoung unnie, do you want to have lunch together today?)

Understanding the nuances of when to use it and who can use it will help you show respect and cultural awareness. Both are extremely important when you speak Korean.

Who Can Use “Unnie” in Korean and When?

Not to gatekeep this fun term, but not everyone can say “unnie.” As we explained earlier, the word is gender and age-specific, used only by female speakers talking with another older female. And it's typically only used in casual or friendly contexts. So, if you use it in the wrong setting or towards the wrong person, there's a chance you'll come across as rude or overly familiar. 

Still not sure if you should use unnie in Korean? Here are a few things to check off first:

• You’re female.
• The person you’re talking to is also female.
• They're older than you by at least a year. Be cautious not to guess someone's age based on appearance, as this could lead to an even bigger faux pas.
• You’re close or friendly with the person you’re speaking to. 

As a Korean speaker, you should avoid “unnie” if:

• You’re talking to a male. Instead, use “oppa” or “hyung.” (More on that later.)
• You’re older than the other female you’re talking to.
• It's a formal situation, or when you're not that close with the female you're talking to. In this case, titles like 선생님 (teacher) are better.

We get it. This one simple term comes with a lot of rules to learn. However, comparing them to other Korean honorifics can help.

“Unnie” vs. Other Korean Honorifics

Telling your “unnie” from other Korean honorifics like “oppa,” “noona,” and “hyung” can feel tricky at first. But for the most part, it depends on the gender of the speaker and the listener, with a few minor exceptions. To avoid any awkward mistakes and know exactly what to say and to whom, here's how “unnie” in Korean compares to other honorifics.

“Unnie” vs. “Noona”

“Unnie” (언니): female → older female.

“Noona” (누나): male → older female.

For example:

• Female to older sister: "언니, 같이 가자." (Unnie, let's go together.)
• Male to older sister: "누나, 같이 가자." (Noona, let's go together.)

“Unnie” vs. “Oppa”

“Unnie” (언니): female → older female.

“Oppa” (오빠): female → older male.

For example:

• Female to older female friend: "지은 언니, 오늘 저녁 같이 먹을래요?" (Jieun unnie, do you want to have dinner together tonight?)
• Female to older male friend: "민수 오빠, 이 노래 알아요?" (Minsu oppa, do you know this song?)

“Unnie” vs. “Hyung”

“Unnie” (언니): female → older female.

“Hyung” (형): male → older male.

For example:

• Female to older female friend: "수진 언니, 이 책 빌려줄 수 있어요?" (Sujin unnie, can you lend me this book?)
• Male to older male friend: "동현 형, 같이 운동하러 갈래?" (Donghyun hyung, do you want to work out together?)
