What Does Annyeong Mean? Korean Hello, Goodbye, and Real Usage

안녕 means hello or goodbye in casual Korean. Written as 안녕 and pronounced /an.njʌŋ/, it is what you say to a close friend, sibling, classmate, or child when you meet them or leave them. Its deeper sense is peace, safety, and wellbeing, which explains why Korean uses the same core word for greetings and farewells.

Korean is spoken by roughly 81 million people worldwide, according to Ethnologue's 27th edition, and it is the official language of both South Korea and North Korea. For learners, 안녕 /an.njʌŋ/ is one of the first Korean words they hear in K-dramas, K-pop content, animation, and casual videos. The key is knowing that its friendly tone is not suitable for every situation.

For a wider set of greetings, see our guide to saying hello in Korean. The short version is simple: use 안녕 /an.njʌŋ/ with people close to you, and use 안녕하세요 /an.njʌŋ.ha.se.jo/ when you need polite Korean.

The core meaning of 안녕

The dictionary meaning of 안녕 /an.njʌŋ/ is peace, safety, wellbeing, or being free from trouble. It is a noun, not originally a direct translation of the English word hello.

That underlying meaning is still visible in polite greetings. 안녕하세요 /an.njʌŋ.ha.se.jo/ literally has the sense of asking whether someone is at peace or well. In daily conversation, though, speakers process it as a normal hello rather than as a serious question about health.

The National Institute of Korean Language lists 안녕 /an.njʌŋ/ with senses connected to peacefulness and wellbeing, as well as its conventional role in greeting and parting. That overlap matters because Korean greetings are built around relational care, not merely a neutral acknowledgment.

Ho-min Sohn, in The Korean Language, explains Korean speech through the interaction of grammar, social rank, age, and interpersonal distance. A greeting is therefore never just a greeting. The form you select signals how you understand your relationship with the listener.

Is 안녕 hello or goodbye?

It can be both. When you arrive, 안녕 /an.njʌŋ/ means hi. When you leave, the same word can mean bye.

English has separate everyday words for hello and goodbye, but many languages reuse greeting formulas at both ends of an interaction. Korean relies on the situation, facial expression, timing, and relationship to establish the meaning.

A teenager entering a friend's room might say 안녕 /an.njʌŋ/. The same teenager might say 안녕 /an.njʌŋ/ while walking away a few minutes later. Neither use is confusing to Korean speakers.

안녕

안녕 /an.njʌŋ/ is short, warm, and casual. It is common in text messages, calls, informal video greetings, and everyday speech between people who are socially close.

The pronunciation is /an.njʌŋ/. The double n sequence comes from the syllable boundary between 안 /an/ and 녕 /njʌŋ/. Do not stretch it into three separate English-like syllables such as ah-nee-young.

The vowel /ʌ/ in 녕 /njʌŋ/ may be difficult at first. It is not the same as the vowel in English go. Listen for it in real dialogue, then repeat the whole word as one compact rhythm.

Why 안녕 can sound rude

안녕 /an.njʌŋ/ is not inherently rude. It becomes inappropriate when it is too casual for the social relationship.

Korean has speech levels that shape verb endings, requests, apologies, and greetings. Age is one factor, but it is not the only one. A customer speaking to staff, an employee speaking to a client, a student greeting a teacher, or a visitor meeting an older relative would normally begin with polite speech.

Use 안녕 /an.njʌŋ/ comfortably with:

• close friends
• siblings and cousins near your age
• classmates after you have become friendly
• younger children
• a romantic partner
• close online friends who use casual speech with you

Avoid opening with 안녕 /an.njʌŋ/ when speaking to:

• a teacher or professor
• a manager or client
• an older stranger
• a shop employee you do not know
• your partner's parents
• someone you have just met in a formal setting

The King Sejong Institute's Korean-learning materials place 안녕하세요 /an.njʌŋ.ha.se.jo/ among the foundational greetings because it covers so many everyday encounters. It is the greeting visitors can use most safely in South Korea.

안녕하세요 is not just a longer 안녕

안녕하세요 /an.njʌŋ.ha.se.jo/ contains the same root, 안녕 /an.njʌŋ/, but its ending makes it polite. It is the standard greeting for adults who do not know each other well.

A cashier may say 안녕하세요 /an.njʌŋ.ha.se.jo/ as you enter a store. You can say it to a taxi driver, a neighbor, a coworker, or a friend's parent. It sounds natural at most times of day, unlike English good morning or good evening.

안녕하세요

The phrase 안녕하세요 /an.njʌŋ.ha.se.jo/ does not require a detailed answer. In ordinary conversation, the other person will usually repeat 안녕하세요 /an.njʌŋ.ha.se.jo/ back to you.

The final 요 /jo/ is a polite ending. It should not be dropped unless you have established a casual relationship. Saying 안녕하세 /an.njʌŋ.ha.se/ without the final 요 /jo/ sounds incomplete and is a common beginner error.

For introductions, pair this greeting with the phrases in our Korean nice-to-meet-you guide. Greeting style matters as much as vocabulary when you make a first impression.

The two polite Korean goodbyes

Unlike casual 안녕 /an.njʌŋ/, polite Korean goodbyes usually tell you who is leaving. This distinction is one of the most useful cultural details to learn early.

If the other person is leaving and you are staying, say 안녕히 가세요 /an.njʌŋ.hi ka.se.jo/. If you are leaving and the other person is staying, say 안녕히 계세요 /an.njʌŋ.hi kje.se.jo/.

The first phrase includes 가다 /ka.da/, to go. The second includes 계시다 /kje.ɕi.da/, an honorific form of to be or stay. You do not need to explain the grammar every time, but recognizing the movement logic helps you choose correctly.

안녕히 가세요

Say 안녕히 가세요 /an.njʌŋ.hi ka.se.jo/ to a guest leaving your home, a coworker leaving the office, or a teacher ending a class while you remain.

안녕히 계세요

Say 안녕히 계세요 /an.njʌŋ.hi kje.se.jo/ when you are the person leaving. For example, you would say it as you leave a host, teacher, receptionist, or colleague who remains where they are.

The two expressions are often taught as rigid opposites, but real conversation can be more flexible when both people leave the same place. In that case, either a casual 안녕 /an.njʌŋ/ among friends or a context-appropriate polite farewell can work. Learn the standard distinction first, then notice how native speakers handle the specific scene.

How Koreans actually use 안녕 in messages

In a chat with a friend, 안녕 /an.njʌŋ/ is a normal opener. It can stand alone, be followed by a name, or appear with a question.

Examples include:

• 안녕, 뭐 해? /an.njʌŋ mwo hɛ/ , Hi, what are you doing?
• 안녕! 잘 지냈어? /an.njʌŋ tɕal tɕi.nɛ.sʌ/ , Hi! Have you been well?
• 나 이제 갈게. 안녕! /na i.dʑe kal.ke an.njʌŋ/ , I am going now. Bye!

Texting can make 안녕 /an.njʌŋ/ feel especially light and friendly. Adding repeated vowels or punctuation, such as 안녕! /an.njʌŋ/, changes enthusiasm rather than formality. The relationship still determines whether the word is suitable.

A useful contrast is 사랑해 /sa.ɾaŋ.hɛ/, meaning I love you in casual Korean. Both 안녕 /an.njʌŋ/ and 사랑해 /sa.ɾaŋ.hɛ/ belong in close relationships, but the first is a routine greeting and the second carries emotional weight. Read our guide on how to say I love you in Korean before using romantic phrases casually.

Formal greetings and ceremonial Korean

You may also hear 안녕하십니까? /an.njʌŋ.ha.ɕim.ni.k͈a/ in news broadcasts, military settings, formal speeches, customer service scripts, and highly respectful introductions. It is much more formal than 안녕하세요 /an.njʌŋ.ha.se.jo/.

The answer can be 네, 안녕하십니다 /ne an.njʌŋ.ha.ɕim.ni.da/, meaning roughly yes, I am well, though this exchange is not required in ordinary conversation. The formality communicates institutional respect and distance.

Jaehoon Yeon and Lucien Brown, in Korean: A Comprehensive Grammar, describe how Korean endings encode social stance alongside grammatical meaning. That is why translating every greeting as simply hello misses the point. Korean speakers choose a form that fits the relationship and setting.

Common learner mistakes with 안녕

The first mistake is saying 안녕 /an.njʌŋ/ to everyone because a drama subtitle says hello. Drama characters often speak to friends, siblings, romantic interests, or peers. Their relationship is part of the line.

The second mistake is treating 안녕하세요 /an.njʌŋ.ha.se.jo/ as a phrase reserved for morning. Korean does not require a different basic greeting for morning, afternoon, and evening. Use it throughout the day.

The third mistake is using 안녕히 가세요 /an.njʌŋ.hi ka.se.jo/ when you are the one walking away. Remember the person who goes is the listener in that phrase.

Korean media is particularly useful for this because greetings recur in predictable scenes: entering a classroom, arriving at work, visiting a home, answering a call, or saying goodnight to friends. For more practice ideas, explore Korean learning with K-dramas.

The practical rule to remember

Use 안녕 /an.njʌŋ/ for hello or goodbye with close friends and peers. Use 안녕하세요 /an.njʌŋ.ha.se.jo/ for a polite hello in nearly every uncertain situation.

For polite farewells, choose 안녕히 가세요 /an.njʌŋ.hi ka.se.jo/ when the other person leaves and 안녕히 계세요 /an.njʌŋ.hi kje.se.jo/ when you leave. Once those four phrases feel automatic, you can greet people naturally without sounding either distant or overly familiar.
