Grammar for Business Korean: Formal & Written Register

In a Korean workplace, the politeness you can be relaxed about among friends becomes load-bearing. Meetings, emails, and documents run on 합니다체 and a dense layer of honorifics that are not optional courtesy but the professional baseline — the register that signals you know how to behave. This roadmap sequences that system in the order you should build it, from the formal sentence endings up through the humble forms that lower you and the honorific nouns and email conventions that make written Korean look properly official.

This is genuinely demanding — expect it to take real time, and expect to keep a reference open for your first months of emails. Work the stages in order; each layer sits on the one before.

Stage 1 — 합니다체: the formal polite endings

The default register of presentations, reports, and any exchange with a client or senior is the formal polite 합니다체: statements end in -ㅂ니다 after a vowel and -습니다 after a consonant, and questions in -ㅂ니까? / -습니까?. Start with the 합니다체 overview and formal present -ㅂ니다/-습니다, add formal questions -습니까, and keep the 합니다체 verb-reference sheet handy. Then read 해요체 vs 합니다체 so you know exactly when to reach for the more formal one.

Stage 2 — Raising the other party: -(으)시- and 께서

The first dial of the seesaw is the subject honorific -(으)시-: you infix it into any verb whose subject is someone you respect — a superior, a client, an elder. It pairs with the honorific subject particle 께서 (replacing 이/가) and dative 께 (replacing 에게/한테). Some everyday verbs are suppletive — they swap for a whole different word: 있다 → 계시다, 먹다 → 드시다/잡수시다, 자다 → 주무시다, 말하다 → 말씀하시다, 죽다 → 돌아가시다. Study the subject honorific -(으)시- and -(으)세요/-(으)십니다, the suppletive honorific verbs — 계시다, 드시다/잡수시다, 주무시다, 돌아가시다/말씀하시다 — and the particles 께서 (subject) and 께 (dative).

Stage 3 — Lowering yourself: humble 겸양 forms

The second dial is 겸양 (humble) forms, which lower the speaker to elevate the listener by contrast. The pronoun is 저/저희 (never 나/우리 with a superior), and several verbs have dedicated humble forms: 주다 → 드리다 ("give" to someone above you, as in 연락드리다), 만나다/보다 → 뵙다/뵈다 ("meet/see" a superior), 묻다 → 여쭙다/여쭈다 ("ask" a superior). The benefactive -아/어 드리다 marks a service you perform for someone senior. Study 저/저희 (humble), 드리다, 뵙다, 여쭙다, the benefactive -아/어 드리다, and the humble verbs sheet. The choice between plain and humble "give" is drilled on 주다 vs 드리다.

Stage 4 — Honorific nouns

Raising the other party reaches the nouns too. A handful of everyday words have honorific twins you use for a respected person: 이름 → 성함 (name), 나이 → 연세 (age), 집 → 댁 (home), 말 → 말씀 (words), and the counter 사람 → 분 (person). Crucially, an honorific noun tends to pull the rest of the clause into agreement — it expects -(으)시- on the verb. Study 성함 (name), 연세 (age), 댁 (home), the honorific-noun set agreement, the honorific nouns reference, and address titles on 씨/님/선생님.

Stage 5 — Email and document conventions

Written business Korean has its own furniture. Emails open with 안녕하십니까, carry a deferential 겠 on your own future actions (검토해 보겠습니다 = "I'll review it"), and sign off with 드림 or the more formal 올림 after your name; a recipient's name takes 귀하. Commands to a client soften to -(으)십시오, and proposals to -(으)ㅂ시다 or a hedged question. Study -(으)십시오 (formal commands) and -(으)ㅂ시다 (formal proposals), the deferential future on 겠 and 겠다 vs -(으)ㄹ 거예요, and see the whole thing assembled in a workplace email, an official email, a formal announcement, and the set greeting 처음 뵙겠습니다.

Stage 6 — Nominal report style: -(으)ㅁ and -기

Reports, notices, and memos compress prose into noun-ending style. The nominalizers -(으)ㅁ and -기 turn a verb into a heading-like noun: 참석 요망 ("attendance requested"), 자료 제출 바람 ("materials to be submitted"), 확인했음 ("confirmed"). This is the terse register of the 개조식 bulleted memo. Study -(으)ㅁ nominalization, -기 nominalization, the -기 vs -(으)ㅁ vs -는 것 comparison, the nominalization pointer, and the written-vs-spoken split on 구어체 vs 문어체, official nominal endings, and written-plain 한다체.

The errors this path exists to correct

Two mistakes mark someone as new to workplace Korean. The first is honoring your own actions — attaching -(으)시- to what you do. -(으)시- raises the subject; when the subject is you, it is self-flattery. See -(으)시- is not for yourself, self-honorification, and mismatched honorification.

The second is sliding into 해요체 mid-document. A report or formal email must hold 합니다체 (or nominal style) throughout; a stray 해요체 sentence reads as sloppy. Keep the register consistent from greeting to sign-off.

And resist over-using 겠 as a blanket "will" — it is deferential and modal, not a plain future tense; see overusing 겠.

Key takeaways

• 합니다체 (-ㅂ니다/-습니다) is the workplace default; hold it consistently across a whole document.
• The seesaw: raise the other party with -(으)시-, 께서/께, and honorific nouns; lower yourself with 저/저희 and humble 드리다/뵙다/여쭙다 — often in the same sentence.
• Written Korean adds email furniture (안녕하십니까, 드림/올림, deferential 겠) and terse nominal -(으)ㅁ/-기 report style.
• Never put -(으)시- on your own actions, and never drift into 해요체 mid-report.
