Korean Terms of Address Explained: Oppa, Unni, Hyung and Noona, 씨 and 님, Workplace Titles, Family and Kinship Words, and How to Address Strangers Politely

One of the first surprises for learners of Korean is how rarely Koreans say "you". In English, "you" works for a child, a friend, a boss and a stranger alike. In Korean, the most common words for "you" can sound rude, overly intimate or strangely formal, depending on the situation. Instead, Koreans address each other with names, titles and family words: a younger woman calls her older friend "unni", an office worker calls a manager "team leader", and a customer calls the woman serving lunch "imo", which literally means "aunt".

These words are called hoching (호칭), or terms of address. They tell you a lot about Korean society, especially the importance of age, relationships and roles. Once you understand the system, Korean conversations, dramas and variety shows suddenly make much more sense. This guide explains the main terms, who uses them, and how to choose the right one without causing offence.

Why Koreans rarely say "you"

Korean does have words for "you". The most common are 너 (neo), used with close friends of the same age or younger and with children, and 당신 (dangsin), which appears in writing, advertising, song lyrics, and between some married couples. Neither is a safe all-purpose choice. Using 너 with someone older or with a stranger is rude, and 당신 can sound cold or even confrontational in an argument.

Because of this, Korean speakers usually do one of three things:

• Use a name or title. Instead of "Are you coming?", Koreans say "Is Minji coming?" or "Is the manager coming?" even when speaking directly to Minji or the manager.
• Drop the subject. Korean sentences often leave out the subject when it is clear from context. "Have you eaten?" becomes simply "Have eaten?" (밥 먹었어요?).
• Use a relationship word. Family terms such as unni, hyung and imo are used not only with relatives but also with friends, colleagues and even strangers.

If you remember just one rule, let it be this: when in doubt, leave out "you" and use the person's name with a polite ending or an appropriate title.

Names with 씨 and 님

Korean names usually have three syllables: a one-syllable family name followed by a two-syllable given name, for example 김민지 (Kim Minji). How you use a name depends on your relationship.

씨 (ssi): polite, but not for superiors

Adding 씨 after a name is a polite way to address adults of similar status, such as colleagues of the same rank, classmates in an adult class or acquaintances. You can use the full name (김민지 씨) or the given name (민지 씨). The given name with 씨 sounds friendlier. However, never use the family name alone with 씨 (김 씨) for someone you respect. It can sound condescending and is sometimes used for manual workers or in rough speech. Also avoid using 씨 for people clearly above you, such as your boss, teacher or someone much older. They need a title instead.

님 (nim): respectful and widely used

님 is a more respectful suffix. It is attached to titles (선생님, 사장님, 부장님) and often to names in customer service, online communities and formal emails (민지 님). In many modern companies and start-ups, colleagues address each other as name + 님 to create a flatter, more equal culture. Customer service staff will call you 고객님 (valued customer), and online you may see usernames followed by 님.

Using a name alone

Using someone's given name without any suffix is only for close friends of the same age, younger people you are close to, or children. With a name that ends in a consonant, friends add 아 (지훈아!), and with a name ending in a vowel they add 야 (민지야!) when calling out. Calling an older person by their name alone is a serious faux pas.

Oppa, unni, hyung and noona: words for older friends

The most famous Korean terms of address are the four words for older siblings, used widely for older friends too. The key point for learners is that the word you choose depends on your own gender, not only the gender of the person you are talking to.

• 형 (hyung): used by a male speaker for an older man.
• 누나 (nuna or noona): used by a male speaker for an older woman.
• 오빠 (oppa): used by a female speaker for an older man.
• 언니 (eonni or unni): used by a female speaker for an older woman.

So the same 25-year-old man is "hyung" to his 22-year-old male friend and "oppa" to his 22-year-old female friend. These words show both closeness and respect for age. They are used with real siblings, cousins, close friends, older classmates and sometimes friendly colleagues. You usually start using them once a relationship becomes warmer, often after the older person says something like "편하게 오빠라고 불러" (just call me oppa).

The words can be combined with names: 민수 형, 지은 언니, 수진 누나. For older friends, this is more natural than using the name alone.

The special feeling of oppa

"Oppa" is also used by women for boyfriends, husbands in some couples, and male celebrities they admire, which is why K-pop fans of all nationalities know the word. Because of this romantic nuance, some women use it carefully with male colleagues or acquaintances. In a professional setting, a title or name with 님 is usually safer.

Younger people: 동생

The word for a younger sibling is 동생 (dongsaeng), and it is also used for younger friends ("my dongsaeng" means a younger friend or sibling). However, you do not usually call someone "dongsaeng" to their face. Older people simply call younger friends by their given name with 아 or 야, or by their name with 씨 in more formal settings.

Which word should I use? A quick table

Person you are addressing	If you are male	If you are female	Notes
Older man (close)	형 (hyung)	오빠 (oppa)	Can follow a name: 민수 형
Older woman (close)	누나 (nuna)	언니 (eonni)	Can follow a name: 지은 언니
Younger friend	Name + 아/야	Name + 아/야	Referred to as 동생
Same-age friend	Name + 아/야	Name + 아/야	Called 친구 (chingu)
Senior at school or work	선배(님)	선배(님)	Gender-neutral
Adult acquaintance, equal status	Name + 씨 or 님	Name + 씨 or 님	Never family name + 씨

Seonbae and hubae: seniors and juniors

At schools, universities, clubs and workplaces, seniority matters. A 선배 (seonbae) is someone who entered the school, club or company before you, and a 후배 (hubae) is someone who joined after you. These words are gender-neutral.

You call a senior "선배" or, more politely, "선배님", sometimes after their name (지훈 선배). Seniors usually call juniors by name. The seonbae-hubae relationship often comes with expectations: seniors may give advice or pay for a meal, while juniors show respect and help with tasks. In Korean dramas set in schools, hospitals or offices, this relationship is a frequent source of both warmth and conflict.

Seniority can be based on entry year rather than age. A 24-year-old who joined a company last year may be a seonbae to a 27-year-old new hire. In such cases, people often negotiate the right terms, and many workplaces avoid confusion by using titles or name + 님.

Workplace titles

Traditional Korean companies address employees by their position title plus 님, not by name. The name can be added before the title for clarity (김 과장님, 이 부장님). Common titles include:

• 사원 (sawon): staff member. Usually addressed by name + 씨 or name + 님.
• 대리님 (daerinim): assistant manager.
• 과장님 (gwajangnim): manager or section chief.
• 차장님 (chajangnim): deputy general manager.
• 부장님 (bujangnim): general manager or department head.
• 팀장님 (timjangnim): team leader.
• 이사님, 상무님, 전무님 (isanim, sangmunim, jeonmunim): executive ranks.
• 사장님 (sajangnim): company president, also the owner of a shop or restaurant.
• 대표님 (daepyonim): CEO or representative, common in start-ups and agencies.

Many companies have simplified these ranks in recent years. Some use English names, some use "프로" (pro) or "매니저" (manager) for everyone, and many use name + 님. When you start a new job in Korea, listen to how colleagues address one another and follow their lead. If you are unsure, ask a colleague; it is a perfectly normal question.

Teachers, professors and professionals

선생님 (seonsaengnim) means "teacher", but it is also a respectful way to address doctors, many professionals and sometimes older people in general. At a hospital, you would call the doctor 선생님, and patients are often called by name + 님 (김민지 님). At university, professors are 교수님 (gyosunim). Lawyers are 변호사님, writers and artists are often 작가님, and directors are 감독님.

Using these titles is not flattery. It is simply the normal, polite way to address people in these roles, and leaving them out can sound abrupt.

Family and kinship terms

Korean kinship vocabulary is detailed. It distinguishes between the father's and mother's side of the family and often between older and younger relatives. You do not need to memorise everything at once, but the basics are useful, especially because many of these words are also used outside the family.

Parents and grandparents

• 아버지 / 아빠: father / dad.
• 어머니 / 엄마: mother / mum.
• 할아버지 / 할머니: grandfather / grandmother.
• 친할머니 / 외할머니: paternal grandmother / maternal grandmother. The prefix 친- marks the father's side and 외- the mother's side, though in daily speech people often just say 할머니.

When talking politely about someone else's parents, use 아버님 and 어머님. These words are also used for parents-in-law.

Aunts and uncles

• 이모 (imo): mother's sister.
• 고모 (gomo): father's sister.
• 삼촌 (samchon): uncle, especially an unmarried uncle on the father's side; often used loosely for any uncle.
• 외삼촌 (oesamchon): mother's brother.
• 큰아버지 / 작은아버지: father's older brother / father's younger brother (once married).
• 사촌 (sachon): cousin.

Words used beyond the family

Several kinship terms are extended to people who are not relatives. Children call their parents' close friends 이모 or 삼촌, and adults use 이모 for friendly women working in restaurants. This habit reflects a culture that often treats close social relationships like family.

Addressing strangers politely

Addressing strangers is where learners most often feel stuck. Here are the most common choices and their nuances:

• 저기요 (jeogiyo): literally "over there", this is the safest way to get the attention of a stranger or a server. "저기요, 이거 얼마예요?" means "Excuse me, how much is this?"
• 실례합니다 (sillyehamnida): "Excuse me" in a more formal way, useful before asking a question.
• 아저씨 (ajeossi): a middle-aged man. It is common, but some men may feel it makes them sound old, so use it with care and avoid it with young men.
• 아주머니 / 아줌마 (ajumeoni / ajumma): a middle-aged or married woman. 아주머니 is more polite than 아줌마, but both can feel uncomfortable for some women. 저기요 or 이모 is often a friendlier option.
• 이모 (imo): a warm, informal way to call a woman working in a casual restaurant or market stall. Regular customers use it often. In a formal restaurant, 저기요 is better.
• 사장님 (sajangnim): used for shop or restaurant owners, and very commonly as a polite term for any adult running a business, even if you do not know if they are the owner.
• 어르신 (eoreusin): a respectful word for an elderly person.
• 학생 (haksaeng): "student", used by older people to address young people, whether or not they are actually students.
• 기사님 (gisanim): used for taxi and bus drivers, and also for delivery drivers.

As a visitor, you will rarely go wrong with 저기요 to get attention and a polite -요 ending. For drivers, 기사님 is warmly received, and for shop owners, 사장님 is always safe.

Couples and spouses

Couples have their own vocabulary. Dating couples often call each other 자기 (jagi, "honey"), 자기야, or by pet names. Many women call their boyfriend 오빠 if he is older. Married couples traditionally use 여보 (yeobo), which is something like "dear". When talking about a spouse to others, people say 남편 (husband) and 아내 or 와이프 (wife), and older people may say 집사람 or 바깥사람. Some married women continue to call their husbands 오빠, which is common in Korean dramas, although some older people find it odd.

Terms of address online and in writing

In emails, messages and online communities, 님 is the default. A formal email might begin with "김민지 님께" or "안녕하세요, 민지 님". In workplace messengers, colleagues may write "팀장님, 확인 부탁드립니다" (Team leader, please check this). On social media and community boards, users address each other by username + 님. In customer service, you will see 고객님 and 회원님 (member). Using 님 shows respect without needing to know someone's age or status, which is why it is so convenient online.

Terms of address in K-dramas and K-pop

Korean dramas and K-pop are a great way to hear terms of address in action, and they also explain many scenes that confuse international viewers. A few patterns appear again and again:

• The shift in address as a sign of romance. In many romantic dramas, the moment a female lead stops calling the male lead by his title or name + 씨 and starts calling him 오빠 marks a turning point in the relationship. Similarly, switching from polite speech to casual speech is often a big emotional moment.
• Office hierarchy. Office dramas show the full range of titles, from 대리님 to 사장님, and how characters use them to show respect, distance or even sarcasm.
• Idol group dynamics. In K-pop groups, members call older members hyung, noona, oppa or unni according to their gender, and fans enjoy seeing which members are the "maknae" (막내, the youngest). The way members address each other often reveals their friendships.
• Family dramas. Weekend family dramas are full of kinship terms such as 큰아버지, 고모 and 외삼촌, which can be a fun way to practise the vocabulary.

When you watch, pay attention to who uses which term and when it changes. This kind of observation helps you understand the social meaning behind the words, which textbooks cannot fully explain.

Common mistakes learners make

• Translating "you" directly. Using 너 or 당신 in polite conversation sounds rude or strange. Use names, titles or drop the subject.
• Choosing by the listener's gender only. Remember that oppa, unni, hyung and noona depend on the speaker's gender too. A man does not call an older woman "unni".
• Using 씨 with superiors. 씨 is for equals. Use a title with 님 for bosses, teachers and older people.
• Family name + 씨. "김 씨" can sound disrespectful. Use the full name or given name with 씨.
• Calling an older person by name only. This is a serious breach of etiquette. Add a title or a kinship term.
• Using oppa too freely. Women learners should know that oppa can sound flirtatious with men who are not close friends.
• Ajumma by default. Some women dislike being called ajumma. 저기요 or 사장님 is safer.
• Ignoring what people want. If someone asks you to call them by a particular term, follow their wish. It is part of building a relationship.

Practice: choose the right term

Try these short scenarios. Think about your answer before reading the explanation.

Scenario 1: a new friend at a language exchange

You are a 26-year-old woman. A 29-year-old man you met at a language exchange has become a friend and tells you to speak casually. A natural choice is 오빠 or name + 오빠 (민수 오빠), as he has invited you to be closer. If you are not comfortable with oppa, you can keep using name + 씨 for a while.

Scenario 2: your first week at a Korean company

Your team leader is Park Jiyoung. Address her as 팀장님 or 박 팀장님. If your company uses name + 님 for everyone, call her 지영 님. Watch what colleagues do and follow the same pattern.

Scenario 3: lunch at a small restaurant

You want more side dishes. Say "저기요, 반찬 좀 더 주세요" (Excuse me, could we have some more side dishes?). If you are a regular and the atmosphere is friendly, "이모, 반찬 좀 더 주세요" sounds warm and local.

Frequently asked questions

Can a man call an older woman "unni"?

No. Unni is used by women for older women. A man calls an older woman noona. Similarly, a woman does not call an older man hyung; she calls him oppa.

Is it rude to call someone "ajumma"?

It is not a rude word in itself, but some women find it unflattering because it suggests middle age. Polite alternatives such as 저기요, 사장님 or, in casual restaurants, 이모 often work better.

When can I stop using titles and use someone's name?

With people of the same age who become close friends, you can usually switch to names after agreeing to speak casually. With older people, you usually keep using a title or kinship term, even after becoming close.

What should I call my Korean teacher?

Call your teacher 선생님. You can add the family name (김 선생님), but never use 씨 or the name alone.

Why do Koreans ask my age so soon?

Age helps people decide which terms of address and speech levels to use. It is not meant to be intrusive. You can answer simply, or politely say you prefer not to share, and people will usually use name + 씨 or 님.

Is 당신 a polite word for "you"?

Not usually in conversation. It appears in songs, poems, advertising and between some spouses, but in everyday speech it can sound cold or confrontational. Use names and titles instead.

Final thought: words that map relationships

Korean terms of address are more than vocabulary. Each word carries information about age, closeness, role and respect, and choosing the right one shows that you understand the relationship you are in. At first, the system may feel complicated, but it quickly becomes natural. Listen to how people around you speak, follow their lead, and do not worry about small mistakes. Koreans generally appreciate learners who make the effort, and being invited to call someone 언니 or 형 is often a sign that you have made a real friend.
