Oppa, unnie, hyung and noona: who uses each Korean family word?
Learn the four older-sibling terms, understand their use outside families, and choose a comfortable way to address someone.
The same older brother can be 오빠 or 형
A woman introduces her older brother as 오빠. His younger brother calls him 형. The older brother has not changed; the word changes with the person speaking. This is the first detail to notice when these words appear in a conversation or a drama.
Start with the family meanings below, then look at what happens between friends. You will learn how to describe a sibling, recognise an affectionate form of address, and ask what someone would like you to call them. You only need short sentences for the practice. If endings such as 이에요 and 예요 are new, keep the noun-sentence guide nearby.
Keep the speaker in the picture
| Who is speaking? | Older male sibling | Older female sibling |
|---|---|---|
| A female speaker | 오빠 · oppa | 언니 · eonni / unnie |
| A male speaker | 형 · hyeong / hyung | 누나 · nuna / noona |
These are the conventional distinctions taught in Korean learner dictionaries. The person referred to is older than the speaker. The terms can also apply to older cousins; this lesson starts with siblings to keep the relationship clear.
Notice that knowing the older person’s gender is not enough. For an older sister, you still need to know who is speaking before choosing 언니 or 누나. The English spellings in the chart are reading aids. Eonni, hyeong and nuna follow Revised Romanization; unnie, hyung and noona are spellings you may already recognise from English-language discussions. The Korean spellings stay 언니, 형 and 누나.
In your own relationships, use a form of address that everyone is comfortable with. These conventional patterns help you understand Korean; they do not require you to decide another person’s identity from their appearance.
What about a younger sibling?
동생 means a younger sibling. To specify a younger brother, use 남동생; for a younger sister, use 여동생. This choice depends on the younger sibling, so both a man and a woman can say 남동생 about a younger brother.
There is also a difference between describing someone and calling to them. “This is my younger brother” can contain 남동생. When getting that brother’s attention, people often use his name. Learning a family noun does not mean it is the usual thing to shout across the room.
Introduce a sibling in one sentence
| Situation | Korean example | Natural English |
|---|---|---|
| A woman introduces her older sister | 우리 언니예요. | This is my older sister. |
| A man introduces his older brother | 우리 형이에요. | This is my older brother. |
| Someone describes a younger brother | 남동생이 있어요. | I have a younger brother. |
| A man talks about his older sister | 누나는 부산에 살아요. | My older sister lives in Busan. |
우리 often appears with family words where English naturally uses “my.” In 우리 언니예요, you do not have to translate 우리 as “our” and assume that the listener shares the same sister. The family relationship and the introduction make the meaning clear. 저희 is a humbler form of 우리, but you do not need to switch every 우리 mechanically to 저희.
Look at the endings: 언니 ends in a vowel, giving 언니예요. 형 ends in a consonant, giving 형이에요. In 남동생이 있어요, 이 marks the younger brother and 있어요 expresses having one in this context. The final example adds a place: 부산에 살아요 means “lives in Busan.”
Outside the family, closeness matters
These terms also occur between people who are not relatives. A woman may call a close older female friend 언니; a man may call a close older male friend 형. In that situation, translating the word as a biological relationship can mislead the listener. English may use the person’s name instead.
오빠 can appear between a woman and an older boyfriend, but the word by itself does not mean “boyfriend.” It can refer to an older brother or a familiar older man. A subtitle, the relationship established in the scene, and the surrounding conversation help you decide which meaning fits.
Do not treat the chart as a rule for addressing every stranger. Calling a newly met coworker 오빠 or an unfamiliar customer 언니 can suggest a degree of familiarity that has not been established. In a class, a teacher’s title may be appropriate. At work, follow the person’s stated name or job title. See names, 씨, 님 and titles for those situations.
The word you use for the person and the ending of your sentence are separate choices. Someone can say 언니 and continue with polite -요 endings. Hearing a friendly title does not automatically mean that both people have agreed to use casual speech.
Ask instead of guessing
| Purpose | Korean | Meaning |
|---|---|---|
| Ask for a preferred form of address | 어떻게 부르면 될까요? | What should I call you? |
| Check a familiar title with an older female friend | 언니라고 불러도 돼요? | May I call you unnie? |
| A reply choosing a name | 그냥 이름으로 불러 주세요. | Please just call me by my name. |
The second question fits a relationship in which a familiar title is already a reasonable possibility. It is not an opening line for every older woman you meet. Listen to the answer and keep using the form the person chooses. If the name is unfamiliar, ask them to repeat it rather than substituting a family term.
For a short role-play, one person introduces an older sibling and the other asks how to address them. Then change the speaker while keeping the sibling the same. That small change tests whether you are choosing from the speaker’s point of view.
Choose the word and explain your choice
- A woman talks about her older brother. Which of the four terms fits?
- A man talks about the same older brother. What changes?
- A man introduces his older sister. Choose 언니 or 누나.
- Both a woman and a man have a younger sister. Can both use 여동생?
- Someone says 오빠 in a drama. Does that word alone establish a romantic relationship?
- You meet an older colleague for the first time. Is age alone a good reason to call that person 형?
- Complete the noun ending: 우리 언니___.
Check the answers and explanations
- 오빠. The speaker is female and the brother is older than her.
- 형, provided the brother is also older than this male speaker. The speaker’s relationship to the person matters.
- 누나. This is the conventional term from a male speaker’s point of view.
- Yes. 여동생 identifies a younger female sibling; it is used by speakers of either gender.
- No. It may refer to a brother or another familiar older man. You need the context.
- No. Use the preferred name or appropriate work title; familiarity is not determined by age alone.
- 우리 언니예요. 언니 ends in a vowel, so this beginner noun pattern uses 예요.
Draw a tiny family with three fictional people. Give each an age and write who is speaking. Make two introductions, then move the speaker label. Checking the relationship on your own drawing is more useful than memorising the English word “brother” beside only one Korean term.
A small listening check
Pronunciation help: Listen to the whole introduction
Keep 언니예요 together rather than pausing before 예요. The name of the relationship carries the main contrast in this listening pair.
