Formal Business Apology (-ㄴ/은/는 바 대단히 죄송합니다)
Grammar Rule in 30 Seconds
Use this structure to express sincere, formal regret in professional settings by attaching the cause of the apology to the suffix '-ㄴ/은/는 바'.
- Use '-ㄴ/은/는 바' to frame the specific situation or error you are apologizing for.
- Follow with '대단히 죄송합니다' to emphasize the gravity of the apology.
- Ensure the verb preceding '바' is in the appropriate tense (past for completed actions, present for ongoing states).
Overview
In Korean, expressing an apology is a nuanced act that reflects social hierarchy, context, and the gravity of the mistake. While beginners learn 미안합니다 and 죄송합니다 for everyday situations, the B2 level demands a more sophisticated tool for professional and public contexts. This is the domain of the formal apologetic structure: -ㄴ/은/는 바 대단히 죄송합니다.
This is not simply a stronger way to say "sorry." It is a grammatical construction for issuing a formal, official apology by first establishing a factual basis for the regret.
At its heart, this pattern separates the action from the apology. It uses the bound noun 바 (ba), meaning "the fact," "the situation," or "the case," to first present the wrongdoing as an objective, acknowledged fact. Then, it attaches a formal statement of regret.
This two-step process creates a tone of high formality, accountability, and respectful distance. It shifts the focus from a personal feeling of being sorry (like in -아/어서 죄송합니다) to a public or corporate acknowledgement of responsibility for a specific event. You will encounter this grammar in corporate press releases, legal documents, public notices about service failures, and the carefully worded apology statements (사과문, sagwamun) often issued by public figures in Korea.
Mastering it is essential for anyone aiming to operate in a professional Korean-speaking environment.
How This Grammar Works
바 (의존 명사, uijon myeongsa). A bound noun cannot be used on its own; it requires a preceding descriptive clause to give it meaning. In this structure, a verb or adjective phrase modifies 바, creating a nominalized clause that means "the fact that..." or "the situation in which...".- 1The Modifying Clause
[Action/State]: This is the first part of the sentence, where you describe the error or problem. For instance,시스템에 오류가 발생했다(An error occurred in the system). - 2The Nominalizer
-ㄴ/은/는 바: This connects to the clause and turns it into a single noun phrase.시스템에 오류가 발생한 바now means "the fact that an error occurred in the system." The tense (past, present) is crucial here and is marked on the verb before바. - 3The Apology
[대단히 죄송합니다]: This is the main clause of the sentence. You are stating your regret about the previously established fact.대단히(daedanhi) means "greatly" or "extremely," adding significant weight to the apology.
시스템에 오류가 발생한 바 대단히 죄송합니다, translates to: "Regarding the fact that an error occurred in the system, we are deeply sorry." This structure is inherently formal and slightly impersonal, which is precisely why it is favored in business and official communication. It conveys that the speaker or organization is taking official, documented notice of the issue and formally expressing regret. It removes the emotional immediacy of a personal apology and replaces it with a structured, accountable declaration.Formation Pattern
[Clause] + -ㄴ/은/는 바 + [Adverb of Degree (Optional)] + [Apology].

When To Use It
- Corporate & Business Communication: This is the primary home for
-ㄴ/은/는 바. It is standard in client-facing emails, official letters, and reports when addressing a problem, error, or delay. - Example (Email):
지난번 보내주신 파일에 오류가 있었던 바, 수정 후 다시 보내드립니다.(Regarding the fact that there was an error in the file you sent last time, we are re-sending it after correction.)
- Public Notices & Announcements (
공지사항): When a company or organization makes a public statement apologizing for an issue, this grammar is almost always used. Think of website banners, app notifications, or public press releases. - Example (Website Notice):
서버 점검이 예고 없이 진행된 바, 이용자 여러분께 큰 불편을 드린 점 머리 숙여 사과드립니다.(As the server maintenance was conducted without notice, we bow our heads in apology for causing great inconvenience to our users.)
- Formal Speeches & Press Conferences: A CEO or public figure delivering a formal apology will use this phrasing to show the utmost sincerity and accountability in a public forum.
- Legal and Official Documents: The objective and fact-based nature of this grammar makes it suitable for documents where acknowledging a specific point is necessary before proceeding.
- Casual Conversation: Never use this with friends, family, or in casual workplace chats. Apologizing for being five minutes late with
늦은 바 죄송합니다would be bizarre. Stick to늦어서 미안해or늦어서 죄송합니다. - Minor Mistakes: This grammar carries significant weight. Using it for a small error diminishes its power and makes you sound out of touch. It is for issues that have a real impact on a customer, client, or the public.
Common Mistakes
- 1Context Misuse (Over-Formality): The most frequent error is using this structure for everyday apologies. It's like wearing a tuxedo to a coffee shop. Remember, this is for official, impactful issues.
어머, 죄송합니다! | 동료의 서류에 커피를 쏟은 바 죄송합니다. |늦어서 죄송합니다. | 회의에 늦은 바 대단히 죄송합니다. |서비스 장애로 불편을 드린 바... | 웹사이트가 고장나서 죄송해요. |- 1Incorrect Tense Application: The tense on the verb before
바is critical. Use-ㄴ/은for completed past actions and-는for present, ongoing actions or general truths.
- Incorrect:
어제 발송이 누락되는 바 죄송합니다.(The verb should be past tense.) - Correct:
어제 발송이 누락된 바 죄송합니다.(We are sorry for the fact that the shipment was missed yesterday.)
- 1Spacing Errors: Because learners are used to grammatical endings that attach directly to stems, they often forget the mandatory space before
바.바is a noun and must be treated as a separate word.
- Incorrect:
심려를 끼쳐드린바... - Correct:
심려를 끼쳐 드린 바...
- 1Mixing Speech Styles: This grammatical pattern locks you into the highest level of formality (하십시오체, hasipsioche). Ending the sentence with a less formal
요(-yo) ending is a jarring mistake.
- Incorrect:
오류가 발생한 바 죄송해요. - Correct:
오류가 발생한 바 죄송합니다.
- 1Confusing
바with데: The noun데(de) can also be used to mean "the case" or "the situation," but it has a different nuance.-ㄴ/은/는데often introduces background information, whereas-ㄴ/은/는 바establishes a formal, objective basis for the main clause.
공사 중인데 시끄러울 수 있습니다.(We are under construction, so it might be noisy - background info).공사로 인해 소음이 발생한 바 죄송합니다.(We apologize for the fact that noise has occurred due to construction - formal apology).
Real Conversations
Because this is a feature of formal, one-way communication, you won't find it in casual back-and-forth chats. Below are three realistic examples of how it is used in the wild.
1. Corporate Email to a Client
Subject
[ABC사] 요청하신 자료 재송부 드립니다.```
김민준 부장님께,
안녕하십니까. ABC사의 박서준입니다.
지난주 요청하신 마케팅 분석 보고서의 일부 데이터에 누락이 있었던 바, 심려를 끼쳐 드린 점 대단히 죄송합니다. 내부적으로 재검토하여 수정한 최종본을 다시 첨부하오니 확인 부탁드립니다.
동일한 문제가 재발하지 않도록 프로세스를 개선하겠습니다.
감사합니다.
박서준 드림
```
Breakdown
데이터에 누락이 있었던 바 ("the fact that there was an omission in the data") establishes the mistake formally and factually before the apology 심려를 끼쳐 드린 점 대단히 죄송합니다 ("we are greatly sorry for causing you concern") is delivered.2. App Update Notice
This is the kind of text you would see in the App Store or Google Play update notes for a Korean app.
```
[v1.2.5 업데이트 안내]
- 일부 기기에서 발생하던 로그인 오류를 수정하였습니다. 앱 이용에 불편을 드렸던 바, 이용자 여러분의 너그러운 양해 부탁드립니다.
- 결제 프로세스의 안정성을 개선하였습니다.
```
Breakdown
불편을 드렸던 바 ("the fact that we caused inconvenience") is a slightly softer version, often paired with a request for understanding (양해 부탁드립니다). It’s still highly formal and acknowledges the user's negative experience as a fact.3. Snippet from a Public Figure's Apology Statement (사과문)
```
먼저 저의 부적절한 언행으로 인해 많은 분들께 실망을 안겨드린 바, 진심으로 고개 숙여 사과드립니다. 공인으로서 더 신중한 모습을 보여드렸어야 했으나, 그러지 못했습니다. 이번 일을 계기로 깊이 반성하고 자숙하는 시간을 갖겠습니다.
```
Breakdown
실망을 안겨드린 바 ("the fact that I caused disappointment") frames the public's reaction as the factual basis for the apology. This is followed by 진심으로 고개 숙여 사과드립니다 ("I sincerely bow my head and apologize"), a classic and very strong combination in public apologies, conveying deep remorse and humility.Quick FAQ
바 in this pattern the same 바 as in 어쩔 줄을 모르다?Yes, it is the exact same bound noun. In 어쩔 줄을 모르는 바 (the situation of not knowing what to do) or 아는 바와 같이 (as is the fact that we know), 바 carries this meaning of "way," "method," "fact," or "situation." Recognizing 바 as a versatile bound noun is key to understanding many advanced grammar points.
대단히?No. 대단히 is a common and strong partner, but other adverbs can be used to modify the nuance.
진심으로 죄송합니다(Sincerely sorry)깊이 사과드립니다(Deeply offer apology)- Or you can use none at all:
...바 죄송합니다.
죄송합니다 and 사과드립니다?죄송합니다 is an adjective-based phrase expressing a state of being sorry/regretful. 사과드립니다 is a verb-based phrase (사과=apology, 드리다=to give humbly) meaning "I offer an apology." In these formal contexts, 사과드립니다 can feel even more official and performative, as it describes the act of apologizing itself. Both are acceptable, but 사과드립니다 is often chosen for the most formal corporate or public statements.
미안합니다 with this pattern?It is grammatically possible but culturally inappropriate. 미안합니다 is considered less formal than 죄송합니다 and is not suitable for the high-formality register that -ㄴ/은/는 바 establishes. Stick to 죄송합니다 or 사과드립니다.
-ㄴ/은/는 바 grammar be used for non-apologies?Absolutely. This is a critical point for advanced learners. The ...바 construction is a general tool for formal statements. A very common related pattern is -ㄴ/은/는 바입니다, which means "It is the case that..." or "I hereby declare that..." It is used for making firm, official announcements.
- Example:
이상으로, 본 계약이 유효함을 확인하는 바입니다.(With the above, it is the case that we confirm this contract is valid.)
