Separate the subject from the listener
In 선생님이 오세요, the predicate, the verb or description that ends the sentence (here 오세요), respects the teacher who is coming. The final polite form also addresses the listener politely. The teacher and the listener need not be the same person. You might be telling a classmate that the teacher is on the way. Identify both conversational roles before deciding what each ending does.
An ordinary polite sentence such as 제가 가요 politely tells the listener that the speaker is going. It does not take the subject honorific 시 just because the listener deserves respect: speakers do not use 시 for their own actions. Adding subject honorification indiscriminately would confuse two different relationships.
The exact choice of speech level depends on the social setting and relationship. This lesson uses ordinary polite final forms while focusing on who receives subject respect. It does not claim to supply a complete etiquette guide. The practical first skill is to distinguish the person being talked about from the person being talked to.
선생님이 오세요.
The teacher is coming.
The teacher is the respected subject; the listener may be someone else.
제가 가요.
I am going.
The final form is polite to the listener without honorifying the speaker as subject.
Build 시 and 으시 from the stem
The stem is the part of the verb before 다. A vowel stem takes 시, while most consonant stems take 으시. In the ordinary polite forms, where 시 and 어요 combine as 세요, 가다 gives 가세요, and 읽다 gives 읽으세요. The resulting form may be a respectful statement, question, or instruction according to context. The visible 세요 ending does not guarantee that the sentence is a command.
A rieul stem, one that ends in the letter ㄹ, drops its rieul before 시. 살다 gives 사세요, and 만들다 gives 만드세요. Compare endings before which the rieul stays, such as 려고 in 만들려고 and 고 in 만들고. The change is tied to the following ending. It is not a general rule to remove rieul whenever a sentence becomes polite.
For practice, begin with a named respected subject and an ordinary action sentence. Then replace the predicate with its honorific form while preserving the action’s object and location. The transformation should change how the subject is presented, not who does the action. Read the whole sentence to check that the new form still matches the intended scene.
선생님이 책을 읽으세요.
The teacher reads a book.
The consonant stem takes 으시 in the honorific form.
할머니가 서울에 사세요.
My grandmother lives in Seoul.
The rieul in 살다 drops before 시.
Honor a respected subject
Say that your grandmother lives in Seoul.
- Choose the subject 할머니.
- Use 서울에 as the location.
- Change the rieul stem 살다 to 사세요.
할머니가 서울에 사세요.
Use special honorific verbs for common actions
Some common meanings have special honorific vocabulary. 주무시다 is used respectfully for sleeping, and 드시다 is used respectfully for eating or drinking. These are not formed by simply adding 시 to the ordinary word. Learn the special verb together with a concrete scene and the person whose action it describes.
For a respected person’s presence in a place, 계시다 is the central form: 선생님이 교실에 계세요. For possession, use 있으시다, not 계시다. Keep being somewhere and having something apart, even though the ordinary verb 있다 covers both.
The construction 고 있어요, for an action in progress, can also respect its subject as 고 계세요, as in a teacher who is reading now. This does not mean every occurrence of 있어요 should be replaced mechanically by 계세요. Identify what 있어요 does in the sentence and who its subject is. Honorific vocabulary works inside meaningful constructions, not as a universal search and replace operation.
할머니가 주무세요.
My grandmother is sleeping.
주무시다 is the special honorific sleeping verb.
선생님이 교실에 계세요.
The teacher is in the classroom.
계시다 respectfully expresses a person’s presence in a place.
Mark respected subjects and recipients differently
The honorific subject particle 께서 can replace the ordinary subject particle 이 or 가 when appropriate: 선생님께서 오세요. It identifies the respected person as the subject. It is not a general respectful replacement for every particle attached to a person’s name or title.
The honorific recipient particle 께 marks the person receiving something or being addressed by a relevant action. The difference between 께서 and 께 is a difference in sentence role. A teacher who comes is the subject; a teacher who receives a letter is the recipient. Respect does not erase the underlying event structure.
Keep objects distinct as well. In a sentence about sending a letter to a teacher, the letter remains the object, even though the recipient is respected. First sketch the event in ordinary terms: sender, item, recipient. Then choose the appropriate respectful forms. This sequence prevents a learner from attaching the subject honorific particle to a recipient merely because that person is important.
선생님께서 오세요.
The teacher is coming.
Unlike 선생님이 오세요 above, this sentence shows respect in the particle as well as in the verb: 께서, the honorific form of 이 or 가, marks the respected subject.
선생님께 편지를 보내요.
I send a letter to the teacher.
께 marks the respected recipient; the speaker is the sender.
Separate recipient from subject
Say that you send a letter to the teacher.
- The speaker is the sender.
- Mark the teacher as recipient with 께.
- Keep the letter as the object and the speaker’s action in ordinary polite form.
Compare your reasoning
선생님께 편지를 보내요.
Recognize respectful nouns that refer to the same things
Some everyday nouns have respectful counterparts when referring to another person appropriately. 성함 can be used for a respected person’s name, 연세 for age, 댁 for home, and 말씀 for words or speech. These forms still refer to the same kinds of things; their social presentation changes.
Do not assume that every noun in a respectful conversation needs an honorific substitute. The person associated with the noun matters. A learner politely stating their own name normally uses the ordinary noun rather than elevating their own name through 성함. Listener politeness can be maintained through the rest of the sentence.
Korean treatment of family members should not be copied from another language’s rules. The cited teaching material includes respect for one’s own senior family members. The models here use a grandmother as a respected subject. They illustrate a common linguistic pattern, while leaving finer choices about relationship, intimacy, and setting to more advanced study.
성함이 어떻게 되세요?
What is your name?
The respectful noun for name pairs with a respectful question ending.
제 이름은 민수예요.
My name is Minsu.
The speaker uses the ordinary noun for their own name.
Interpret statements, questions, and requests in context
A 세요 form can appear in a respectful statement about a subject or in an instruction to the listener. 선생님이 읽으세요 can report that the teacher reads, while 읽으세요 addressed to someone can ask or tell that person to read. The surrounding words, situation, and intonation show whether it is a statement, a question, or an instruction.
A helpful action request with 읽어 주세요 has its own structure. It asks the listener to perform reading as a favor. Do not construct it by simply placing 주세요 after an already complete 세요 form. The main verb takes the 아/어 form (the ordinary polite form without 요) before the request auxiliary, the helping verb 주세요.
Negative instructions use 지 마세요. Ordinary negative reports use their own negative predicate, and honorific subject marking can be combined with those predicates where appropriate. For a beginner exchange, keep the request or report purpose explicit. This makes it easier to learn the respectful form without accidentally changing what the speaker is doing conversationally.
이 문장을 읽으세요.
Please read this sentence.
In this classroom instruction, the listener is asked to read.
이 문장을 읽어 주세요.
Please read this sentence for me.
The helpful action request uses the 아/어 form before 주세요.
Check the social roles before adding forms
Use a short role check when preparing an utterance. Identify the listener, the subject of the predicate, and any recipient. Then ask whether a special honorific verb or noun is relevant. This prevents the familiar mistake of treating respect as one suffix that can be placed anywhere in the sentence.
In the choice game, some alternatives differ only in grammatical role, while others differ in speaker perspective or word meaning. Explain the specific mismatch. Do not describe an ordinary vocabulary item as inherently rude in every setting; each practice situation determines which respectful form is requested.
For production, report a respected person’s location and one action, then write a sentence in which that person is the recipient of a letter. Finally, state your own action politely without subject honorification. Retrieve these on a later day and verify that the participants remain the same. Accurate respect depends on knowing who is meant as well as on correct forms.
선생님께서 책을 읽고 계세요.
The teacher is reading a book.
The subject particle and ongoing predicate both respect the teacher.
저는 도서관에서 공부해요.
I study at the library.
The speaker addresses the listener politely without honoring themselves as the subject.
