Key facts

  • Korean honorific speech is classified into a formal style (격식체) with four grades and an informal style (비격식체) with two, but only three of these are in active everyday use.
  • 해요체 (polite informal) is the safe default for foreign residents in virtually every situation outside close friendships.
  • 안녕 is 반말 (casual speech). Saying it to a stranger or older person reads as rude, not friendly.
  • Asymmetrical 반말 is completely normal: your senior may use casual speech to you while you continue using polite speech to them.
  • The switch to 반말 has its own ritual name: 말 놓기. It is initiated by the senior person, never demanded.
  • Younger Korean companies like Kakao have introduced English-name policies partly to sidestep speech-level friction at work.

You are talking to a Korean colleague you have known for three months. One afternoon they stop mid-sentence and switch from 가요 to 가. The subject is the same. The meaning is the same. But something just changed.

That shift is not random. Your colleague decided, consciously or not, that the relationship had reached a point where formal speech felt unnecessary. In Korean, speech level encodes social relationship in real time. Every sentence you say announces how you see the person you are talking to.

This guide explains the three speech levels you will actually encounter, when each one applies, and how to handle the switch when it comes.


The three levels in active use

Korean honorific speech (공손법) is classified into a formal style (격식체) and an informal style (비격식체). The formal style is divided into four grades, traditionally named 하십시오체, 하오체, 하게체, and 해라체. The informal style is divided into two grades: 해요체 and 해체 (also called 반말). Popular grammar guides sometimes count a seventh, the archaic 하소서체 once used to address royalty, but it does not appear in daily speech.

Most of these grades are rare in modern conversation. 하오체 has fallen out of active use. 하게체 and 해라체 survive mostly in writing, set phrases, and speech to juniors. 해라체 in particular appears in books, newspapers, and reported speech rather than in everyday talk.

That leaves three in active everyday use.

Honorific verbs you will hear constantly

Some verbs have entirely separate respect forms. Use these when speaking to or about anyone older or senior:

Plain formHonorific / humble formMeaning
먹다드시다 / 잡수시다to eat
자다주무시다to sleep
있다계시다to be / to stay
주다주시다 (honorific) / 드리다 (humble)to give

Korean has two parallel respect systems. Honorific forms (존경어) lift up the subject, the respected person doing the action: 드시다, 주무시다, 계시다, and 주시다 (when an elder gives something). Humble forms (겸양어) work the other way, lowering the speaker to show deference: 드리다 is the humble form of 주다, used when you are the giver and the recipient deserves respect. 잡수시다 is an honorific for 먹다 mostly heard from or toward the most-elderly relatives; 드시다 is the everyday choice.

You will hear 드세요, 주무세요, 계세요 from elders far more often than the plain forms.

Three levels in active use:

LevelKorean nameEnding markerUse it when
Formal honorific하십시오체-ㅂ니다 / -습니다Business meetings, presentations, broadcasting, formal service
Polite informal해요체-아요 / -어요Almost everything else: coworkers, strangers, service workers, anyone older
Casual해체 / 반말-아 / -어Close friends, family, romantic partners, people younger than you

How one verb looks across all three levels

가다 (to go)

하십시오체 (formal)해요체 (polite informal)해체/반말 (casual)
갑니다가요

감사하다 (to be grateful)

하십시오체해요체해체/반말
감사합니다감사해요고마워

The endings are the signal. Same verb root, different social meaning.


해요체 is your safe default

Use 해요체 with everyone and you will almost never cause offense. That is the rule. It is polite without being stiff. It works at a convenience store, at a job interview, with a neighbor you just met, and with anyone older than you.

해요체 is what you hear most often in everyday Korean life outside close friendships. Service workers use it with customers. Colleagues use it across departments. Most strangers default to it with each other.

When you are learning Korean and unsure which level to use: use 해요체. You can refine later.


존댓말 in detail: 합니다 vs 해요

Both 합니다 form and 해요 form are 존댓말 (respectful speech). The difference is register, not politeness level.

합니다 form (하십시오체) is formal. Use it when speaking to a large group, giving a presentation, speaking with someone significantly older or senior, or in any institutional setting where you want to project professionalism. If you are introducing yourself at a company dinner, use 합니다 form.

해요 form (해요체) is warm and approachable. It is the right register for daily life: your landlord, a coworker you see every day, a shopkeeper. It is never rude. It is simply less formal than 합니다.

In practice, most foreign residents settle into 해요체 for most situations and reach for 합니다 form when the setting feels clearly formal.


반말 decoded

반말 (半말) means literally "half speech." The politeness markers have been removed. What remains is the base of the word.

반말 is not rude by itself. Among close friends, family members, and romantic partners, 반말 is the constant. Most conversations Koreans have in their daily lives, with people they are close to, are in 반말.

What makes 반말 complicated for foreign residents is that it is context-dependent. The same speech that sounds warm and natural between friends sounds dismissive or insulting directed at a service worker or a stranger.

The social rule: 반말 is for people you are genuinely close to (친해지다), or for people clearly junior to you. Not for anyone else.


The 말 놓기 ritual

The switch from 존댓말 to 반말 has a name: 말 놓기, literally "placing words down." It is a recognized social moment, not just a grammar change.

The protocol is clear. The senior person, whether older by age or higher by role, initiates. Common phrases:

  • 우리 말 놓을까요? (Shall we drop the formality between us?)
  • 말 편하게 해요. (Speak comfortably.)

The junior person accepts:

  • 그럼 그렇게 할게요. (Then I'll do that.)

If you want to invite someone to speak more casually to you (without you switching), you can say:

  • 편하게 말씀해 주세요. (Please speak comfortably.)

That last phrase is useful when a senior person is still using 존댓말 with you but you sense they would be more comfortable switching. It grants permission without making the switch mutual.

One thing to avoid: assuming the switch has happened without it being stated. If someone has not explicitly invited you to use 반말, keep using 존댓말 with them.


Asymmetrical 반말 is normal

You will encounter this situation: someone older or more senior than you speaks to you in 반말, while you continue speaking to them in 해요체 or 합니다 form.

This is not rude. It is not condescending. It is the expected structure of a hierarchical relationship in Korean social convention.

Your senior using 반말 to you says: I see you as someone I'm comfortable with, in a close or superior relationship. You maintaining 존댓말 says: I respect your seniority. Both messages are being sent correctly at the same time.

Foreign residents sometimes feel uncomfortable in this dynamic because it looks unequal. It is unequal, but in Korean social terms it is functioning exactly as intended. Mirror their 반말 back to them only if they explicitly invite you to.


Honorific vocabulary

Honorifics in Korean extend beyond verb endings. Some nouns have entirely different honorific forms when used about elders or respected people.

Regular wordHonorific formMeaning
진지meal
나이연세age
home
사람person
엄마 / 아빠어머님 / 아버님mother / father (someone else's, or your in-laws)

You will hear these in use constantly. 연세가 어떻게 되세요? is "How old are you?" when asking an elder respectfully. 몇 살이에요? is the same question in 해요체, fine for peers. Using 나이 to ask an elder's age sounds blunt.

You do not need to memorize all of these before leaving home. Knowing they exist means you will recognize them when you hear them and understand why a Korean might gently correct you.


The -(으)시- marker

When you are talking about someone who deserves respect, you add -(으)시- to the verb stem.

Example: 선생님이 오늘 일찍 오셨어요. (The teacher came early today.)

Here 오셨어요 = 오다 (come) + -(으)시- (subject-honorific marker) + past tense + 해요체 ending.

The marker is about the subject of the sentence, not about the person you are speaking to. You use it when the person you are talking about is senior or respected, regardless of who you are speaking to.

You do not use -(으)시- to refer to yourself. That would be overcorrecting and sounds strange.

For practical purposes: when you talk about your boss, your elder, or a teacher, add -(으)시- to the verb. You will hear this constantly and your ear will develop quickly.


Common mistakes foreign residents make

Saying 안녕 to a stranger or elder. 안녕 is 반말. You picked it up from dramas. Dramas use it because the characters are close. Use 안녕하세요 with anyone you do not know well.

Using 반말 with a service worker. This reads as dismissive, sometimes insulting. Even if you think you are being casual and friendly, the other person hears: you have decided we are not on equal footing. Use 해요체 with service workers, cashiers, delivery drivers, and anyone in a service context.

Staying with 존댓말 too long with close friends. The reverse problem. After months or years with a close Korean friend who has already invited you to use 반말, staying formal starts to signal distance or coldness. Accept the switch when it is offered.

Refusing the 말 놓기 invitation. If a Korean friend asks you to switch to 반말, declining can feel like rejection to them. Accept it even if your Korean is not fluent yet. Using imperfect 반말 is fine. Refusing the invitation is awkward.

Overcorrecting with -님. Adding -님 (an honorific suffix) to every name and title sounds performatively formal. 선생님 (teacher) is correct. 직원님 (employee, with 님) to a service worker is unusual and slightly odd. Use it for formal titles, not reflexively.

Mixing levels. Switching between 합니다 and 해요체 mid-conversation without reason sounds grammatically confused. Pick one and stay with it for a given conversation.


What to actually do

Here are the practical rules for foreign residents:

Default to 해요체. This is your baseline for almost every interaction: coworkers, neighbors, strangers, anyone older, service workers. You will almost never be wrong.

Use 합니다 form for clearly formal situations. Company presentations, meeting seniors for the first time, formal introductions, settings that feel institutional.

Do not use 반말 unless you have been invited to. Wait for the other person to initiate. This applies even if you have known someone for a year.

Accept the 말 놓기 invitation when it comes. Your Korean is not perfect. That is fine. 반말 from a friend is a gesture of closeness. Accept it.

Let asymmetrical 반말 stand. If someone senior uses 반말 to you, keep using 존댓말 back. That is the correct response.

Use honorific nouns when speaking about elders. 연세, 진지, 댁, 분. You do not need to get these perfect immediately, but recognizing them matters.


What is changing in 2026

Some younger Korean companies have introduced English-name policies, where colleagues use first-name English terms with each other instead of Korean names plus 씨 or titles. Kakao is the best-known example: it has used English names among employees, including for its founder, from its early days. The logic: English names sidestep the speech-level question entirely. If everyone calls the CEO by their English name, there is no speech-level signal embedded in that address.

This is a real trend, but it is confined to specific company cultures. It does not reflect the broader workplace. Most Korean companies still use titles and 존댓말 hierarchies. If you work at a startup that tells you to use English names from day one, your experience will be different from someone at a traditional conglomerate.

Among younger Koreans more generally, mutual 반말 between new acquaintances of similar age appears to be more common than in previous generations, especially on messaging apps. This is a directional observation, not a documented rule change. The safe assumption remains: start with 해요체, wait for the invitation.

The underlying logic of the system, that speech level encodes relationship and that the senior person sets the terms of that encoding, has not changed. It is rooted in 장유유서 (長幼有序), the Confucian principle that there is an order between elders and the young. That principle has shaped Korean social structure for centuries and is one of the threads running through the history covered in the modern Korean history guide. The system softens at the edges over generations. It does not disappear.


Honorifics at work

Korean workplace honorifics have their own layer of complexity: titles, department hierarchies, and how to address a senior colleague all compound the speech-level question. If you are working at a Korean company, the working at a Korean company guide covers the practical application in that context.

The deeper layer of Korean social reading, the unspoken awareness of how others are feeling and adjusting your behavior accordingly, is called 눈치. A full guide on 눈치 is coming.

Frequently asked questions

Which speech level should I use as a foreign resident?

Use 해요체 (the -아요/-어요 form) as your default in every situation: service workers, coworkers, neighbors, people you just met, anyone older than you. 해요체 is polite without being stiff. It works everywhere except close friendships and family. When in doubt, 해요체 is always the right answer.

Why is my Korean friend apologizing for using 반말 to me?

Because they switched to casual speech without asking first. Koreans are socialized to treat that switch as a named ritual: 말 놓기. Doing it without permission, especially toward someone older or a new acquaintance, is technically a social breach. Your friend is being polite by acknowledging it. You can reassure them by accepting the switch: 괜찮아요, 편하게 말씀해 주세요. (It's okay, please speak comfortably.)

Is it okay if my boss uses 반말 to me but I use 존댓말 back?

Yes. This asymmetrical pattern is completely normal in Korean workplace relationships. Your boss using 반말 to you does not mean they are being disrespectful. It reflects the hierarchical structure. You continue using 해요체 or 합니다 form to them. That is the expected and correct behavior. Do not mirror their casual speech back unless explicitly told to.

Show all 7 questions

Why can't I just say 안녕 like in K-dramas?

안녕 is 반말. Dramas use it constantly because most scenes are between close friends, romantic partners, or family members. In real life, saying 안녕 to a stranger, a service worker, or anyone older reads as rude or strange. The polite greeting is 안녕하세요 (해요체) or 안녕하십니까 (formal). Use those with anyone you do not know well.

What is -(으)시- and when do I use it?

It is a marker inserted into the verb stem to signal that the subject of the sentence deserves respect. For example: 선생님이 오늘 일찍 오셨어요 (The teacher came early today, with 오셨 = 오다 + -(으)시- + past tense). You use it when talking about a respected person, not when talking about yourself. It operates independently of speech level: you can use -(으)시- in both 해요체 and 합니다 form.

How do I know when to switch to 반말 with someone?

Wait for the other person to suggest it. In Korean social convention, the senior person (by age or role) initiates the switch with a phrase like 우리 말 놓을까요? (Shall we drop the formality?) or 편하게 말해요 (Speak comfortably). If someone invites the switch, you can accept by saying 그럼 그렇게 할게요 (Then I'll do that). If you want to invite someone to use casual speech with you, say 편하게 말씀해 주세요. Never demand the switch or assume it has happened.

Are these speech-level rules really still strict in 2026?

The rules are real and observed, but younger Koreans are less rigid, especially at certain workplaces. Some tech companies have adopted English-name policies partly to sidestep the speech-level issue at work. On messaging apps, 해요체 is common even between close friends. That said, using 반말 with a stranger or elder remains a clear social mistake regardless of generation. The system is evolving at the edges, not disappearing.

    Korean honorific speech (공손법 / 상대경어법) is classified into a formal style (격식체) and an informal style (비격식체).

    격식을 차려서 말해야 하는 상황에서 사용하는 격식체와 격식을 차리지 않아도 될 만큼 가깝거나 친한 사이에서 서로를 높이거나 낮추는 비격식체로 구분할 수 있다
    encykorea.aks.ac.kr
  • 02

    The formal style (격식체) is divided into four grades, named 하십시오체, 하오체, 하게체, and 해라체.

    아주높임, 예사높임, 예사낮춤, 아주낮춤의 네 등급으로 분류된다 ... '하십시오체(합쇼체)', '하오체', '하게체', '해라체'로 불리기도 한다

    The informal style (비격식체) is divided into two grades, 해요체 and 해체 (also called 반말).

    비격식체는 두루높임과 두루낮춤 두 등급으로 분류되며, 이들은 각각 명령형 종결어미를 따라 각각 '해요체'와 '해체'로 불리기도 하며, '해체'를 반말(체)이라고도 한다
    encykorea.aks.ac.kr
  • 04

    해요체 is the most widely used speech grade in everyday modern conversation, while 하오체 has fallen out of active use, leaving three grades (하십시오체, 해요체, 해체/반말) in active everyday use.

    해요체 ... 오늘날 일상 대화에서 가장 폭넓게 쓰이는 등급이다 ... 하오체 ... 현대국어에서 그 쓰임이 활발하지 못하다

    Korean honorification (경어법) is classified into three types by what is honored: 주체경어법 (subject), 객체경어법 (object), and 상대경어법 (addressee).

    국어의 경어법은 예우의 대상이 무엇이냐 따라 세 가지로 구분된다 ... 주체경어법(主體敬語法), 객체경어법(客體敬語法), 상대경어법(相對敬語法)

  • 06

    Korean honorification uses special honorific vocabulary, including 진지 (for a meal), 댁 (for a home), and the verb forms 주무시다 (sleep), 계시다 (be/stay), and 잡수시다 (eat).

    '진지, 치아, 약주, 댁, 계씨(季氏), 자당, 가친, 함씨, 저, 상서, 주무시다, 계시다, 잡수시다, 돌아가시다…'등과 접미사나 접두사가 붙어서
    encykorea.aks.ac.kr
  • 07

    The subject-honorific is expressed by adding the marker -시- to the verb stem to signal respect toward the subject of the sentence (as in 아버지가 오신다).

    높여 대우할 때만 '아버지가 오신다.'에서처럼 서술어의 어간에 주체존대 표시의 선어말어미 '-시-'를 첨가하여 표현한다
    encykorea.aks.ac.kr
  • 08

    The plain verbs 먹다 (eat) and 있다 (be/stay) are replaced by separate suppletive honorific forms (보충법), for example 잡수시다 and 계시다.

    '좌시다(먹다)·겨시다(잇다)' 등 보충법에 의하여 교체되나
    encykorea.aks.ac.kr
