Honorific Subject Particle 께서: Meaning, Rules and Examples

What you'll learn

• Replace 이/가 with 께서 for a teacher, elder or senior person.
• Pair 께서 with -(으)시- or an honorific verb.
• Tell 께서 (the doer) from 께 (the receiver).
• Decide when 이/가 plus -(으)시- is enough.

Before you start: you should know the subject particle (see 은/는 vs 이/가) and the honorific ending (see honorific -(으)시-). Time: about 25 minutes.

What Does the Honorific Subject Particle 께서 Mean?

The honorific subject particle 께서 means that the person who does the action is someone to respect. A subject is the person or thing that does the action of the verb. A particle (조사, josa) is a short word that attaches to a noun and shows its job. An honorific is a form that shows respect for a person through grammar.

Korean marks respect in two places at once. The particle shows it on the subject, and the verb ending shows it on the action. In 선생님께서 오셨어요, 께서 respects the teacher, and the 시 inside 오셨어요 respects the teacher's action. English has no matching grammar, so the translation is just "The teacher has come".

The neutral version is 선생님이 왔어요. It is correct, but it treats the teacher like anyone else. The difference is not about politeness to the listener, which the ending -어요 already provides. It is about respect for the person being talked about.

A First Example

Listen to each sentence at normal speed, then slowly.

1. 선생님께서 오셨어요. (seonsaengnimkkeseo osyeosseoyo) "The teacher has come."

Pronunciation: [선생님께서 오셔써요]. The verb 오다 ("to come") gains the honorific 시, and 시 + 었 + 어요 contracts to 셨어요. The sentence has three parts: 선생님 (teacher) + 께서 (honorific subject), and 오셨어요 (has come, honorific and polite).

2. 할머니께서는 주무세요. (halmeonikkeseoneun jumuseyo) "Grandmother is sleeping."

Pronunciation: [할머니께서는 주무세요]. The spelling and the sound match. The topic particle 는 is added to 께서, giving 께서는, because Grandmother is the topic of the sentence. The verb is 주무시다, the honorific verb for "to sleep", and its polite form is 주무세요.

Both sentences replace 이/가 with 께서 and use an honorific verb form. The next section gives the rule and the verb pairs.

How Does the Honorific Subject Particle 께서 Work?

The honorific subject particle 께서 works by replacement: attach 께서 to the noun for the respected person, and put -(으)시- or an honorific verb on the predicate. The form is the same after a vowel and after a consonant, so no choice is needed.

Other particles stack after 께서 in the usual way. Add 는 for the topic (선생님께서는), 도 for "also" (선생님께서도) and 만 for "only" (선생님께서만). The lesson on subject particle 이/가 shows the neutral pattern that 께서 replaces.

Pattern Table

The table shows that only the particle changes. Pronunciation of the example 아버지께서 신문을 읽으세요 is [아버지께서 신무늘 일그세요]: before a vowel, the ㄹ of the double final ㄺ in 읽 stays, and the ㄱ moves onto the next syllable.

The verb side of the pattern follows a second table. Some verbs add -(으)시- to the stem, and some verbs have a separate honorific verb. The lesson on Korean honorific verbs 드시다 주무시다 계시다 lists the full set.

Three details make the tables easy to apply.

1. No space. The particle attaches to the noun: 선생님께서, never 선생님 께서.
2. No change after consonants or vowels. 선생님 ends in a consonant and 할머니 ends in a vowel; both take 께서.
3. The verb must agree. A subject with 께서 needs an honorific verb. The two travel as a pair.

After the form, the next section builds a full sentence one piece at a time.

Worked Example: Saying "Grandmother Is Sleeping"

To say "Grandmother is sleeping" with respect, write 할머니께서는 주무세요. Put the respected person first with 께서는 attached, then the honorific verb in its polite form. Use these steps to build any honorific sentence.

1. Decide whether the subject deserves respect. Grandmother is an elder, so the answer is yes.
2. Choose the particle. The subject particle 께서 replaces 이/가. Because Grandmother is also the topic, add 는: 할머니께서는.
3. Choose the honorific verb. The plain verb is 자다 ("to sleep"), and its honorific verb is 주무시다.
4. Make the polite form. 주무시 + 어요 contracts to 주무세요.
5. Check the pair. Particle and verb both show respect.

You'll know it worked when 께서 touches the person noun and the verb has 시 or 세 inside it. Common mistake at this step: using the plain verb 자요. 할머니께서는 자요 mixes an honorific particle with a plain verb, so use 주무세요.

For a neutral sentence, the same idea would be 할머니가 주무세요, which keeps -(으)시- but uses 이/가. That version is common in conversation and is the subject of the next comparison.

How Is 께서 Different from 이/가 and 께?

께서 and 이/가 both mark the subject, and 께서 adds respect. 께 is a different particle: it marks the person who receives something. Register is the level of formality of a word or style, and 께서 sits one step higher than 이/가 on that ladder.

The pair that confuses learners most is giver and receiver. 선생님께서 학생에게 책을 주셨어요 means "The teacher gave a book to the student": the teacher is the doer, so 께서. 학생이 선생님께 책을 드렸어요 means "The student gave a book to the teacher": the teacher is the receiver, so 께. The lesson on 에게 한테 께 indirect object particles covers the receiver side in detail.

An expert rule of thumb: ask who does the action. If the respected person does it, use 께서. If the respected person receives it, use 께. After the contrast, the next section covers how often 께서 appears in real speech.

When Do You Use 께서, and When Not?

Use 께서 for a respected person who does an action, especially in writing and formal speech. In relaxed conversation, 이/가 plus -(으)시- is enough. Four patterns cover most of what you will see.

1. Formal speech and writing. News, letters, speeches and ceremonies use 께서 for senior figures: 대통령께서 말씀하셨습니다 ("The president said").
2. Respect for family elders. 할머니께서 전화하셨어요 ("Grandmother phoned") shows warmth and respect. Grandparents and parents often receive 께서 in writing and careful speech.
3. Work and school. 교수님께서 한국어를 가르치세요 ("The professor teaches Korean") is natural when you describe a professor to a third person.
4. Everyday speech. Spoken Korean often keeps 이/가 even for elders if the verb carries -(으)시-: 할머니가 오셨어요 is correct and common. 께서 raises the formality by one step; it is not required.

The register ladder. From lowest to highest respect, the same sentence can read 할머니가 왔어요 (neutral), 할머니가 오셨어요 (honorific verb) and 할머니께서 오셨어요 (honorific particle and verb). The middle rung is the most common in conversation.

Honest limits of 께서.

• People only. 께서 follows a person who deserves respect. Companies, animals and things do not take it.
• Body parts and belongings. The respected person takes 께서, but the body part keeps 가: 할아버지께서는 키가 크세요 ("Grandfather is tall"). Writing 키께서 is wrong. The honorific ending agrees with the person, not the body part. The lesson on the double subject construction in Korean explains this two-noun pattern.
• Yourself and equals. 께서 never follows 저, 나, a friend or a younger person.

These limits lead directly to the errors learners make most often.

What Mistakes Do Learners Make with 께서?

Five mistakes cover most errors. Each follows the pattern "learners often assume X, but actually Y, because Z."

1. Using 께서 without -(으)시-. Learners often say 선생님께서 왔어요 because 께서 already shows respect. Actually the particle and the verb must agree, so say 선생님께서 오셨어요.
2. Using 께서 for yourself or a peer. Learners often say 친구께서 or 저께서 to sound polite. Actually 께서 raises the subject, so for yourself use 제가 and for a friend use 친구가.
3. Confusing 께서 with 께. Learners often write 선생님께서 선물을 드렸어요 for "I gave the teacher a gift". Actually 께서 marks the doer, so the sentence says that the teacher gave a gift; write 선생님께 선물을 드렸어요.
4. Putting 께서 on a body part. Learners often write 할머니 다리께서 아프세요. Actually the respect goes on the person, so write 할머니께서는 다리가 아프세요.
5. Thinking 께서 is required for every elder. Learners often avoid 이/가 with elders out of fear. Actually 할머니가 오셨어요 is correct and common; the verb ending carries the main respect.

A reliable self-check: find the verb first. If it has 시, 세 or an honorific verb, the subject may take 께서. If the verb is plain, the subject takes 이/가.

Practice and Answers

Try all four items before you read the answers. Each answer has audio, normal and slow.

1. Choose the form. Your company president has come. Which sentence is correct? (a) 사장님이 왔어요. (b) 사장님께서 오셨어요.
2. Fix the error. 선생님께서 왔어요. ("The teacher has come.")
3. Translate. "Grandfather is eating rice." Use 께서 and an honorific verb.
4. Write your own. Write one sentence about what a professor or teacher does, using 께서.

Answer Key

1. (b) 사장님께서 오셨어요. (sajangnimkkeseo osyeosseoyo) Sounds like [사장님께서 오셔써요]. Both the particle and the verb show respect. Sentence (a) is grammatical but treats the president neutrally.

2. 선생님께서 오셨어요. (seonsaengnimkkeseo osyeosseoyo) Sounds like [선생님께서 오셔써요]. The particle 께서 needs an honorific verb, so 왔어요 becomes 오셨어요.

3. 할아버지께서 밥을 드세요. (harabeojikkeseo bapeul deuseyo) Sounds like [하라버지께서 바블 드세요]. The honorific verb 드시다 replaces 먹다, and 드시 + 어요 contracts to 드세요.

4. Sample answer: 교수님께서 한국어를 가르치세요. (gyosunimkkeseo hangugeoreul gareuchiseyo) "The professor teaches Korean." Sounds like [교수님께서 한구거를 가르치세요]. Any sentence with a respected person, 께서 and a verb with -(으)시- is correct.

If an item went wrong, return to the pattern tables and check that the particle and the verb match. Then continue with the next lessons.

Next Lessons and Where to Go from Here

After the honorific subject particle 께서, the next lesson is the double subject construction in Korean, which shows how a respected person and a body part or trait fit in one sentence. For the verb side, read honorific -(으)시- and Korean honorific verbs 드시다 주무시다 계시다. To avoid common slips, see Korean honorific mistakes, and for the neutral pair, see 은/는 vs 이/가. All of these belong to the Korean topic and subject particles set.

For practice, use the grammar quizzes. This page uses Revised Romanization only as a learning aid; the Hangul is the reference. The whole lesson fits in one sentence: the honorific subject particle 께서 replaces 이/가 for a respected person and must travel with -(으)시- on the verb.

Frequently Asked Questions

What Does 께서 Mean?

께서 is the honorific form of the subject particle 이/가. It marks the person who does the action and shows respect for that person: 선생님께서 오셨어요 means "The teacher has come". The verb must carry -(으)시- as well. 께서 has no English word of its own; English shows respect with titles or tone.

How Do I Form 께서?

Attach 께서 to the noun for the respected person, with no space and no change after a consonant or a vowel: 선생님께서, 할머니께서, 아버지께서. For the topic, add 는: 선생님께서는. Then put -(으)시- on the verb or use an honorific verb such as 드시다 or 주무시다.

What Is the Most Common Mistake with 께서?

The most common mistake is using 께서 without -(으)시- on the verb: 선생님께서 왔어요 is incomplete, and 선생님께서 오셨어요 is correct. A second mistake is using 께서 for yourself, a peer or a younger person. It is reserved for people you respect, such as elders, teachers and bosses.

Can Other Particles Follow 께서?

Yes. 는, 도 and 만 attach after 께서: 선생님께서는 (topic), 선생님께서도 (also) and 선생님께서만 (only). The order is fixed: 께서 comes first, then 는, 도 or 만. 이/가 never follows 께서, because 께서 already marks the subject. The verb still needs -(으)시-: 할머니께서도 오셨어요.

Do I Use 께서 in Speech, Writing or Both?

Both, but it leans toward writing and formal speech. News, letters, speeches and ceremonies use 께서 often. Everyday conversation frequently keeps 이/가 and relies on -(으)시- alone: 할머니가 오셨어요 is natural. Use 께서 when you want extra respect, especially with teachers, grandparents and senior colleagues.
