Korean Honorifics and Age: How Should Visitors Address People?

Short answer: as a visitor, you will rarely get Korean honorifics badly wrong, because people do not expect foreigners to know the system. Use the polite ending -yo (as in annyeonghaseyo and gamsahamnida), add -nim or -ssi to names instead of using names bare, call staff with a polite phrase like jeogiyo ("excuse me"), and do not ask people their age just to be polite. That covers almost every situation a traveller meets.

Why age and status matter in Korean

Korean grammar changes depending on who you are talking to. The same sentence can be said in a casual form for close friends and younger people, a polite form for most everyday situations, and a formal form for official or very respectful settings. Age, seniority at work and how well you know someone all shape which form people choose. That is why Koreans who meet for the first time sometimes ask each other's age or birth year: it helps them decide how to speak.

For a short trip, you only need the polite form. It is the safe default with shop staff, taxi drivers, hotel workers and strangers of any age.

The three endings you will hear most

Polite: -yo

Most of what you hear in shops and cafes ends in -yo: annyeonghaseyo (hello), juseyo (please give me), gwaenchanayo (it's okay). If you only learn one rule, learn this one. Ending your phrases with -yo sounds friendly and respectful.

Formal: -mnida / -mnikka

You will hear this in announcements, from airline crews and in formal shops: gamsahamnida (thank you), hwanyeonghamnida (welcome). It is perfectly fine for you to use gamsahamnida anywhere.

Casual: banmal

Casual speech (banmal) drops the polite endings. Friends of the same age use it, and older people sometimes use it with much younger people. As a visitor, avoid it with strangers, even if you hear it a lot in dramas and K-pop lyrics. Wait until a Korean friend suggests "let's speak comfortably" (pyeonhage malhae).

How to address people by name

-ssi: a polite suffix for adults of similar status, usually with the full name or given name (for example, Minji-ssi). Do not attach it to your own name.
-nim: more respectful. Used for customers (gogaek-nim), teachers (seonsaeng-nim) and bosses. Shop staff may call you gogaek-nim or sonnim (guest).
Job titles: at work, Koreans often use titles instead of names, such as sajang-nim for a business owner. Calling a small restaurant owner sajang-nim is common and friendly.

Avoid calling an older person by their given name alone. If you are unsure of a name, you can simply skip it and use polite phrases.

Family words used for strangers

Koreans often use family terms for people who are not family. You do not need to use these yourself, but knowing them helps you understand what is going on around you:

Oppa / hyung: older brother (said by a woman / by a man). Also used for older male friends.
Eonni / nuna: older sister (said by a woman / by a man).
Imo: aunt. Customers often call a middle-aged woman working in a small restaurant imo, warmly.
Ajumma / ajeossi: middle-aged woman / man. These are common but can feel blunt, so visitors are better off with jeogiyo.
Halmeoni / harabeoji: grandmother / grandfather, used respectfully for elderly people.

What about Korean age?

You may have read that everyone in Korea is a year or two "older" than abroad. Since June 2023, Korea uses international age (counting from birth, going up on your birthday) for legal and administrative purposes. In daily conversation, some people still think in the old way or ask your birth year instead, especially when working out who is older. As a visitor, nobody will expect you to calculate this. If someone asks your age, answering with your international age is fine, and it is fine to smile and change the subject if you prefer.

Small gestures that show respect

Give and receive cards, money and gifts with two hands, or with your right hand while your left hand lightly touches your right arm.
A small nod or bow when saying hello or thank you goes a long way.
At a meal with older people, let the eldest start eating first, and turn your head slightly away when drinking alcohol with them.

LUMI from POPORO CITY puts it simply: "Add -yo, smile, and you are already polite enough."

Quick tips

Default to -yo endings with everyone you do not know.
Say jeogiyo to get attention in a restaurant instead of calling someone ajumma.
Use -ssi or -nim with names; never use them for yourself.
Do not switch to casual speech until a Korean friend invites you to.
Two hands for giving and receiving is a simple, visible sign of respect.

FAQ

Will Koreans be offended if I use the wrong form?

Very rarely. Most people appreciate any effort from visitors. Using polite -yo forms keeps you safe in almost every case.

Is it rude to ask someone's age in Korea?

Between Koreans it is a common way to sort out how to speak. As a visitor, you do not need to ask, and it can feel personal coming from a stranger.

Can I call a K-pop idol or a Korean friend "oppa"?

Fans do it all the time with idols. With a real person, it suggests closeness, so use it only if you are a woman speaking to an older male friend who is comfortable with it.

What should I call a waiter or shop assistant?

Say jeogiyo ("excuse me") or sillyehamnida ("pardon me"). Both are polite and work everywhere.
