Which Korean Speech Level to Use: Meaning, Rules and Examples

What you'll learn

• Apply three questions in order to choose formal, polite or casual speech.
• Match a listener type (stranger, boss, friend, family) to a level.
• Explain how a relationship moves from polite to casual over time, and who proposes the change.
• Fix the most common mistake: using casual speech with a stranger who looks younger.

Before you start: you should know that Korean has speech levels, which are sets of sentence endings that show how a speaker ranks the listener. The lesson on seven Korean speech levels names them all. This lesson uses only three. Audio plays only when you press a button.

What Does Choosing Which Korean Speech Level to Use Involve?

The question of which Korean speech level to use is a choice among three practical levels. 하십시오체 is the formal level, with endings such as -ㅂ니다. 해요체 is the polite level, with endings such as -아요/어요. 해체 is the casual level, with endings such as -아/어. Every Korean sentence must pick one.

Why does the choice matter so much? In English, the same sentence works for a king and a classmate. In Korean, the ending itself shows the relationship, so a wrong choice sends a message that the speaker did not mean. A polite ending with a friend feels distant. A casual ending with a manager feels disrespectful.

Two sentences show the range:

• 안녕하세요? 처음 뵙겠습니다. (annyeonghaseyo? cheoeum boepgetseumnida.) [처음 뵙껟씀니다] = "Hello. Nice to meet you." The speaker uses a polite greeting and a formal fixed expression for a first meeting.
• 밥 먹었어? (bap meogeosseo?) [밥 머거써] = "Did you eat?" The speaker uses a casual ending with a close friend.

A First Example, Labelled

In the first example, 안녕하세요 is the polite greeting, 처음 means "first time", and 뵙겠습니다 is the humble verb 뵙다 (to meet a respected person) in the formal ending -겠습니다. In the second example, 밥 means "meal", 먹었어 is 먹다 in the past casual form, and the question mark carries the rising tone. The next section turns the examples into a procedure.

How Does the Choice of a Korean Speech Level Work?

The choice of a Korean speech level works as a short procedure. Ask three questions in order, and stop at the first yes. The questions move from the setting to the person to the agreement between you.

1. Is the setting public or official? Presentations, announcements, interviews, ceremonies, news and a first meeting at work call for formal 하십시오체.
2. Is the person older, higher in rank, a stranger, or someone you just met? If yes, use polite 해요체. This answer covers most daily situations.
3. Have we agreed to be casual, and is the person your age or younger? If yes, you may use casual 해체. If there was no agreement, stay at question 2.

If none of the questions gives a clear yes, use 해요체. It is the level that works almost everywhere.

Pattern Table

The table matches common listeners to a level and gives the same question, "Did you eat?", at each level.

Three details in the table deserve attention.

First, the honorific marker -(으)시- is a separate choice. 식사하셨어요? respects the person who ate, and 밥 먹었어요? does not. The lesson on honorific vs polite speech in Korean explains the two layers.

Second, the polite level covers the widest range of rows. A learner who masters only 해요체 can talk with everyone except in the most official settings. The lesson on when to use polite speech in Korean lists the cases.

Third, the formal and casual levels each have their own lesson: when to use formal speech in Korean and when to use banmal.

The table covers the main rows. The worked example shows how the three questions run.

Worked Example: Choosing a Level for One Question

Choosing a level takes four steps. The situation: you want to ask "Did you eat lunch?" at a new job, and three different people are nearby.

1. Listener A is your manager, and you are in a team meeting. Question 1: is the setting formal? A meeting is semi-official, so formal speech is allowed: 점심 식사하셨습니까? In a relaxed team lunch, question 2 applies instead and the polite 점심 드셨어요? is better.
2. Listener B is a coworker your age you met last week. Question 1: no. Question 2: yes, because you just met. Use polite: 점심 먹었어요?
3. Listener C is a friend of five years who told you to talk casually. Question 1: no. Question 2: no, because you are close. Question 3: yes, there is an agreement. Use casual: 점심 먹었어?
4. Read the results. A: 점심 식사하셨습니까? (jeomsim siksahasyeotseumnikka?) B: 점심 먹었어요? (jeomsim meogeosseoyo?) C: 점심 먹었어? (jeomsim meogeosseo?)

You will know it worked when each sentence matches one yes in the questions and the answer to the earlier questions was no. The most common slip is skipping straight to question 3 because the listener is the same age. Age alone does not give permission. The next section covers how the right level changes over time.

How Does the Right Level Change over Time in One Relationship?

The right level in one relationship usually moves from polite to casual, one step at a time, and only after an agreement. A new coworker, a classmate or a language partner begins at polite speech. Months later the same pair may use casual speech. The change is marked by a spoken invitation.

The invitation phrases matter. 말 편하게 하세요 (mal pyeonhage haseyo) means "Please speak comfortably", and 말 놓을게요 (mal noeulgeyo) means "I will drop the formal speech". The senior or the older person normally says them. A learner who starts with 말 놓아도 돼요? ("May I speak casually?") to an older person risks sounding pushy, so wait for the other person to offer.

An example shows the same pair at two times. In the first month, a junior says 부장님, 점심 드셨어요? to a department head. Years later, the same junior may call a long-time mentor 선배 in private and say 선배, 밥 먹었어요?, with a polite ending but a less formal title. The speech level is a living part of the relationship, not a fixed label.

The progression shows how the right level changes. The next section covers cases where the rules bend.

When Do You Use Each Level, and When Not?

Use each level according to the three questions, and keep four exceptions in mind. Each one gives the rule and an example.

• Learners are forgiven more when polite. Native speakers expect foreign learners to make mistakes, and a polite mistake is easy to forgive. A casual mistake to an elder is harder to forgive. This is a tendency, not a rule, but it means too formal is the safer error.
• Age and rank can disagree. A younger manager may receive polite speech from an older junior in a meeting, while the same pair may use casual speech outside work if they agree. When age and rank disagree, polite speech is safe.
• Family habits vary. Many Korean families use polite speech with grandparents and casual or half-polite speech with parents, and some families use polite speech with parents, too. Watch the household and follow it.
• Service staff. Staff in shops and restaurants speak to customers in polite or formal speech, and customers in return usually answer with polite speech. Casual speech to staff is rude, even when the staff member is younger.

An honest limit: this lesson gives a safe procedure, not a law. Korean speakers differ by region, generation and workplace, and online comment sections follow looser rules. It does not teach the endings themselves. For the endings, study the lessons on formal speech -ㅂ니다/습니다 and 해요체 polite speech -아요/어요.

The exceptions show that the procedure has safe defaults. The next section lists the mistakes that appear when learners skip a question.

What Mistakes Do Learners Make When Choosing a Level?

Learners usually make five mistakes, and each one has a quick repair.

1. Using casual speech with a stranger who is a few years younger. Learners often assume that age alone gives permission. Actually, adults who do not know each other use polite speech even when one is younger. Fix: say 밥 먹었어요? to a new classmate, not 밥 먹었어?
2. Staying formal with a friend for years. 하십시오체 between friends sounds like a news report. Fix: move to polite speech and then to casual speech when the friend invites it.
3. Starting casual speech yourself with an older person. 말 놓아도 돼요? from a junior can sound pushy. Fix: wait for the older person to offer.
4. Choosing by age only. A younger manager is still your manager at work. Fix: add rank and setting to the question.
5. Mixing casual endings into a polite sentence. 밥 먹었어요? 근데 나 안 먹었어. changes level in one turn. Fix: keep the same level for the same listener, except for planned mixing in the lesson on mixing -요 and -ㅂ니다 in Korean.

Use this checklist when you hesitate: Which of the three questions did I answer yes to? Did I skip a question? Does the verb ending match the listener? Practice puts the checklist to work.

Practice and Answers

Try the four items before you read the answer key. Cover the answers with your hand.

1. Choose the form. You meet a coworker for the first time. Complete: 처음 뵙겠습니다 / 처음 봐. Which fits?
2. Fix the error. A learner says 밥 먹었어? to a classmate they met today, who looks younger. What is a safer question?
3. Translate. "Did you eat lunch?" to your manager at a team lunch. Use a polite honorific ending.
4. Write your own. Write one sentence for a close friend and one for a client, choosing the level for each.

Answer key

1. 처음 뵙겠습니다. The fixed formal expression suits a first meeting. 처음 봐 is casual and would be too forward.
2. 밥 먹었어요? New acquaintances use polite speech even when one is younger.
3. 점심 드셨어요? (jeomsim deusyeosseoyo?) The honorific verb 드시다 plus the past marker and 어요 respects the manager and keeps the polite ending.
4. Answers vary. A model pair: 밥 먹었어? for the friend and 식사하셨습니까? for the client. Check that the friend sentence has a casual ending and the client sentence has the formal ending with an honorific.

A rule of thumb for checking your own work: when two levels both seem possible, choose the one that is more respectful, then listen to how the other person answers and follow their level.

Next Lessons after Which Korean Speech Level to Use

After which Korean speech level to use, study the situations for each level and the full ladder. This lesson gives a choice procedure but does not teach every ending or every social setting.

1. Read seven Korean speech levels to see the whole system.
2. Study when to use polite speech in Korean for the default level.
3. Study when to use formal speech in Korean for public settings.
4. Study when to use banmal for friends and younger people.
5. Compare respect for the listener with respect for the subject in honorific vs polite speech in Korean.
6. Return to Korean speech levels to see every lesson in the set.

With these steps, the question of which Korean speech level to use becomes a habit: ask about the setting, then the person, then the agreement, and default to polite speech.

Frequently Asked Questions

Which Korean speech level is the safest default?

Use polite speech with -아요/어요. It is respectful enough for strangers, shop staff, teachers and coworkers, and friendly enough for most daily talk. Switch to formal -ㅂ니다 for presentations, official announcements and first meetings at work. Switch to casual only with close friends and younger people who have agreed to it.

How do I know when I can use casual speech?

Wait for an invitation. The older or higher-ranking person usually proposes it, with phrases such as 말 편하게 하세요 or 말 놓을게요. Same-age friends often agree after a few meetings. If nobody has said anything, stay polite. A learner should not be the first to switch with an older person.

Does age or rank matter more?

Both matter, and the setting can override either. At work, rank often decides: a younger manager may receive polite speech from an older junior in a meeting. Outside work, age usually decides. Koreans often ask about age early, partly to choose a level. When the two disagree, polite speech is safe.

Can I speak casually to a younger stranger?

Usually not. Adults who do not know each other use polite speech, even when one is clearly younger. Casual speech to a stranger a few years younger can sound arrogant. Teachers speaking to children, and older people speaking to teenagers they know, are the common exceptions. Foreign learners should stay polite.

Should I use the same level with my parents?

Families differ. Many Korean families use polite speech with grandparents and casual or half-polite speech with parents, but some use polite speech with parents too, and the habit varies by region and household. Watch what the family does and follow it. When you are unsure, use polite speech with honorific verbs.
