Korean Terms of Address: Oppa, Unnie, Noona & Hyung

Korean terms of address are the words Koreans use to call someone instead of using a name, such as oppa, unnie, noona, hyung, ahjussi and sunbae. This guide links 8 phrase pages, each with a lead Korean word, an English meaning and an audio clip, and it shows how to pick the right term from your gender, the listener's gender and their age.

What Are the Most Useful Korean Terms of Address to Learn First?

Learn four Korean terms of address first: 오빠 (oppa), 언니 (unnie), 형 (hyung) and 누나 (noona). They cover older siblings and older friends, and they are the words you hear most in dramas, songs and daily life. Then add 아저씨 (ahjussi), 동생 (dongsaeng), 선배 (sunbae) and 아줌마 (ajumma).

Order Korean Revised Romanization Who it names Page
1 오빠 oppa Older brother or older male friend, said by a woman oppa in Korean
2 언니 eonni Older sister or older female friend, said by a woman unnie in Korean
3 형 hyeong Older brother or older male friend, said by a man hyung in Korean
4 누나 nuna Older sister or older female friend, said by a man noona in Korean
5 아저씨 ajeossi Middle-aged man, mister ahjussi in Korean

How Do You Choose the Right Korean Term of Address?

Choose the term from three facts: your own gender, the listener's gender and whether the listener is older. Korean has no everyday gender-neutral word for an older sibling, so the speaker's gender and the listener's gender split the idea into four words.

You are... Older brother or older male friend Older sister or older female friend
A woman 오빠 (oppa) 언니 (unnie)
A man 형 (hyung) 누나 (noona)

Three points make the table work in daily life:

  • Family and friends. The same four words name real siblings and are also used for older friends, classmates and partners. The relationship, not blood, sets the word. A cousin is 사촌 오빠 (older male cousin, said by a woman) or 사촌 형 (said by a man).
  • Age is counted by birth year. People born one year earlier are usually treated as older, so a friend a year or two older may be 오빠 or 언니 to you. People born in the same year are 동갑 and often become casual friends.
  • Younger people are 동생. 동생 (dongsaeng) is the general word for a younger sibling or younger person, with 남동생 for a younger brother and 여동생 for a younger sister.

Strangers and seniors at work use different words. 아저씨 and 아줌마 name middle-aged men and women, and 선배 names a senior at school or work. Because the first two can sound blunt, the mistakes section lists safer choices. Each word has its own guide below.

All Korean Terms of Address Guides

The list below has all 8 guides, each with its lead word and a short audio clip. Start with the four main pages, then use the alphabetical list for the rest. Every published guide follows the same layout: a quick answer, a register table, pronunciation with audio, usage scenes, short dialogues and common mistakes. The Korean phrases hub holds the other situation clusters.

Ahjussi in Korean

The lead word is 아저씨 (ajeossi), which means "middle-aged man" or "mister". The page shows when it is friendly, when it sounds blunt and which titles replace it with strangers.

Noona in Korean

The lead word is 누나 (nuna), which means "older sister" when a man speaks. The page covers the honorific 누님 and the tone of using 누나 for an older female friend.

Unnie in Korean

The lead word is 언니 (eonni), which means "older sister" when a woman speaks. The page covers its use for older female friends and coworkers and its pronunciation [언니].

Sunbae in Korean

The lead word is 선배 (seonbae), which means "senior in school or work". The page covers the polite 선배님, the matching word 후배 for a junior and the entry-year rule.

How Do You Practise Korean Terms of Address?

Practise Korean terms of address in three steps: listen, repeat, then name a real person. Play the clip on a guide once, say the word aloud twice, and then think of someone you know who fits it. The phrase flashcards drill this cluster with audio. Add the word after a name in a sentence, as in 민수 오빠, 어디 가요? ("Min-su oppa, where are you going?"). The word comes after the name, not before.

What Mistakes Do Learners Make with Korean Terms of Address?

Most mistakes come from picking the term by the wrong gender, or from using a blunt word with a stranger.

Mistake Why it is a problem Fix
A man says 오빠 to his older brother 오빠 is only for a female speaker Say 형
A woman says 누나 누나 is only for a male speaker Say 언니
Calling a stranger 아줌마 or 아저씨 Can sound blunt or ageing Say 사장님 in a shop, 선생님 or 아주머니
Using 오빠 for any older man Can sound romantic or presumptuous Use it only after a friendly bond
Using 선배 for a same-year classmate 선배 means joined earlier Use the name or 친구 for same-year peers

Learners often assume these words are only for family. In fact, they are the everyday way to show respect and closeness among friends, and the right term often replaces the person's name altogether. The guide to Korean older sibling titles explains how family titles replace "you" in grammar, and the page on Korean family members lists the true kinship words for real relatives. Use these Korean terms of address as a reference, and return to a guide whenever a new relationship appears.

Frequently Asked Questions

What does oppa mean?

오빠 (oppa) is what a woman calls an older brother, and it extends to an older male friend or a boyfriend. The meaning depends on the relationship and the tone, so the same word can be family, friendly or romantic. A man never uses it for his own older brother, because he says 형.

Can a man say oppa?

No. A man calls his older brother 형 (hyung) and an older sister 누나 (noona). 오빠 is only for a female speaker. The one exception is a man quoting or joking about the word, such as imitating a fan. In normal speech, speaker gender decides the term.

Is it rude to say ajumma?

It can be. 아줌마 (ajumma) means a middle-aged woman, and some women hear it as blunt or ageing when it comes from a stranger. Safer choices are 아주머니 (more respectful), 사장님 for a shop owner or 선생님 in some settings. Among family and neighbours, it is common and friendly.

What is a sunbae?

선배 (seonbae) is a senior at school or work, someone who joined before you. The younger person is a 후배 (hubae). A junior calls a senior 선배 or the polite 선배님, and the title can follow a name. The senior-junior bond is based on entry year, not on age alone.

Is "older" counted by birthday or birth year?

Usually by birth year. People born in the same year are 동갑 (the same age) and often drop formal speech as friends, even when their birthdays are months apart. Someone born one year earlier is an older sibling figure, which is why 오빠 and 언니 are used for older friends of a few years.
