Written and Formal Style in Korean

In Brief

Formal Korean prose often states information with the plain declarative endings -다, -ㄴ다, and -는다, rather than the polite conversational endings -요 or -습니다. It also uses 바 either as a spaced bound noun meaning “fact, matter, or what…” or, in -는바, as part of a formal connective meaning “as” or “since.” These forms are common in reports, essays, news, public notices, and academic writing, but a formal presentation may still use polite -습니다 endings when addressing an audience.

Overview

Korean “formal style” is not one single set of endings. The writer chooses a register according to the text’s purpose and audience. Expository writing—writing that presents or explains information—commonly uses the 해라체 plain style, whose neutral statements end in -다, -ㄴ다, or -는다. Although this style is called “plain,” it is not automatically casual. In a report, article, or textbook, it can sound objective, compact, and appropriately formal.

At C1, the challenge is less about forming one ending and more about controlling an entire text. English often uses essentially the same verb form in an academic article, a newspaper report, and a conversation. Korean marks the difference much more visibly through sentence endings, vocabulary, compression, and constructions such as 알려진 바와 같이 (“as is known”) or 발표한 바에 의하면 (“according to what was announced”). Switching endings without a reason can make a paragraph feel unstable even when every sentence is grammatical.

A second challenge is recognizing 바. A bound noun (a noun that normally needs another word before it) is written with a space: 검토한 바, “what was reviewed” or “the result of reviewing.” By contrast, connective -는바 is attached to the preceding stem and links clauses with a formal sense such as “as,” “since,” or “given that.” The space changes the grammatical analysis and often the meaning.

How It Works

1. Plain declarative endings

The plain declarative is built differently according to the predicate. A predicate is the part that says what happens or what something is like—usually a Korean verb, descriptive verb, or the copula 이다 (“to be”).

Predicate type	Formation	Example	Meaning
Action verb, vowel-final stem	stem + -ㄴ다	가다 → 간다	goes
Action verb, stem ending in ㄹ	drop ㄹ + -ㄴ다	살다 → 산다	lives
Action verb, other consonant-final stem	stem + -는다	먹다 → 먹는다	eats
Descriptive verb	dictionary-form -다	중요하다 → 중요하다	is important
있다 / 없다	있다 / 없다	문제가 있다	there is a problem
Copula / negative copula	이다 / 아니다	원인이다 / 원인이 아니다	is the cause / is not the cause

The special present-tense marking -ㄴ다/-는다 belongs to action verbs. Do not add it mechanically to descriptive verbs: 높다 means “is high,” not 높는다 in the ordinary descriptive sense.

Tense and other markers come before final -다:

Time or meaning	Pattern	Example	Translation
Past	-았/었다	연구를 진행했다.	The study was conducted.
Inference or retrospective realization	-더라 and related forms	차이가 크더라.	The difference turned out to be large.
Intention, prediction, or formal future	-겠다	다음 절에서 살펴보겠다.	We will examine this in the next section.
Negative statement	-지 않다	결과가 일치하지 않는다.	The results do not agree.

Plain style does not mean that every sentence must be a statement. Questions, commands, and proposals have their own plain-style forms, but in formal informational prose writers often avoid directly commanding the reader. Instructions may use -기 바란다 (“it is requested that…”) or noun-like labels, while questionnaires and interviews may use question forms suited to their genre.

2. Choosing between -다 style and -습니다 style

Both can be formal, but they organize the relationship with the reader differently.

Style	Main effect	Typical settings
-다/-ㄴ다/-는다	impersonal, concise, documentary	essays, reports, articles, textbooks, much news prose
-습니다/-ㅂ니다	politely addresses a listener or reader	speeches, presentations, customer notices, formal correspondence
-요	polite and conversational	interviews, explanatory dialogue, blogs with a friendly voice

This explains why 이상으로 마치겠습니다 (“I will conclude here”) is natural in a presentation. The speaker is directly addressing listeners, so polite formal -겠습니다 fits better than documentary 마친다. A written transcript may therefore contain both plain narrative and polite quoted speech without inconsistency.

3. 바 as a bound noun: “fact, matter, what…”

When 바 is a noun, a modifier comes before it. A modifier is a form that describes a following noun, comparable to the relative clause in English “the result that was announced.” Because 바 is a separate noun, put a space before it.

Relationship to 바	Pattern	Example	Approximate sense
Present or ongoing action	verb + -는 바	현재 추진하는 바	what is currently being pursued
Completed action	verb + -(으)ㄴ 바	조사한 바	what was investigated; upon investigating
State or descriptive meaning	descriptive modifier + -(으)ㄴ 바	필요한 바	what is needed
Expected or intended matter	verb + -(으)ㄹ 바	고려할 바	a matter to consider

The exact English translation depends on the expression. 바 is not always best translated as “thing.” It can refer to a fact, content, circumstance, experience, result, intention, or course of action.

Common formal frames include:

• 알려진 바와 같이 — as is known
• 앞에서 언급한 바와 같이 — as mentioned above
• 발표한 바에 의하면 — according to what was announced
• 조사한 바에 따르면 — according to the findings of the investigation
• 검토한 바 있다 — have examined; there is a past instance of examining
• 그러한 바 없다 — there is no such fact or instance
• 고려할 바가 많다 — there is much to consider

In 조사한 바, the completed modifier -ㄴ does not by itself force one fixed tense for the whole sentence. The main predicate still anchors the sentence in time. In the fixed-looking pattern -ㄴ 바 있다, the construction often reports prior experience or an officially relevant past action.

4. Attached -는바: “as, since, given that”

Connective -는바 joins one clause to the next. A clause is a group of words built around a predicate. The first clause supplies a circumstance, reason, or basis for the following statement:

본 연구는 자료가 제한적인바, 결과 해석에 주의가 필요하다. “Since this study has limited data, caution is needed when interpreting the results.”

Here -는바 is an ending, not a noun, so it is attached with no space. It has a distinctly formal, written, and sometimes legal or old-fashioned flavor. In ordinary speech, -아서/어서, -(으)니까, or -기 때문에 will usually sound more natural.

The most useful learner contrast is visual and functional:

Form	Analysis	Function
검토하는 바	modifier + bound noun	what is being reviewed; the matter being reviewed
검토하는바, …	attached connective	as/since [someone] reviews it, …

Real examples are not always equally natural with both analyses, but the pair makes the spacing rule clear. In contemporary formal prose, noun 바 expressions are much more broadly useful than productive connective -는바. Use the connective selectively rather than inserting it wherever English has “because.”

Common Mistakes

Adding -는다 to every predicate

• Wrong: 이 결과는 중요한다.
• Right: 이 결과는 중요하다.
• Why: 중요하다 is descriptive: it states what the result is like. Present -ㄴ다/-는다 marks action verbs, not ordinary descriptive predicates.

Using a dictionary form instead of the action-verb statement form

• Wrong: 회사는 새 제도를 도입하다.
• Right: 회사는 새 제도를 도입한다.
• Why: A dictionary lists 도입하다, but a present plain-style statement with an action verb is 도입한다. English-speaking learners may overlook this because English dictionaries and present statements can look similar; Korean distinguishes them.

Forgetting the space before noun 바

• Wrong: 알려진바와 같이
• Right: 알려진 바와 같이
• Why: Here 바 means the known fact or content. It is a bound noun and is spaced from its modifier.

Separating connective -는바

• Wrong: 자료가 부족한 바, 추가 조사가 필요하다. (if the intended meaning is “since the data are insufficient”)
• Right: 자료가 부족한바, 추가 조사가 필요하다.
• Why: In the intended causal reading, -는바 is a connective ending and attaches to the predicate. A spaced 바 invites a noun analysis and may produce a different or awkward reading.

Mixing registers sentence by sentence

• Awkward: 본 연구는 원인을 분석한다. 먼저 자료를 살펴보겠습니다. 결과는 다음과 같아요.
• Better for a report: 본 연구는 원인을 분석한다. 먼저 자료를 살펴본다. 결과는 다음과 같다.
• Why: -다, -겠습니다, and -요 each create a different relationship with the audience. A deliberate quotation or change from report to presentation can justify a switch; random alternation cannot.

Treating -는바 as an everyday equivalent of “because”

• Awkward in conversation: 피곤한바 집에 갈게요.
• Natural conversation: 피곤해서 집에 갈게요.
• Why: Attached -는바 is strongly written and formal. In conversation, use an ordinary causal connector unless you intentionally want a stiff or humorous effect.

Usage Notes

Formality is more than the final ending

A paragraph does not become academic merely by replacing -요 with -다. Formal Korean also favors explicit logical links, stable terminology, restrained evaluation, and compact Sino-Korean vocabulary where appropriate. Conversely, too many heavy frames—-는바, ~에 의거하여, ~에 있어서—can make prose bureaucratic rather than clear. Modern professional writing often prefers a straightforward sentence when it conveys the same meaning.

Subjects may be omitted, but evidence must remain clear

Korean readily leaves out a subject when context identifies it. Formal writing, however, must make clear who made a claim and what evidence supports it. Compare 발표한 바에 의하면 with 기관이 발표한 바에 의하면. If several possible announcers have been mentioned, naming 기관이 prevents ambiguity.

News, academic prose, and literature are not identical

News headlines often omit particles and endings for space and impact, while the body of an article generally uses complete sentences. Academic prose relies on definitions, evidence, cautious claims, and references to sections. Literary prose may use the same -다 endings but manipulate rhythm, sentence length, tense, and viewpoint. Learning plain style gives access to all three, but it does not erase their genre differences.

Punctuation and paragraph consistency matter

A comma often follows a fronted frame such as 알려진 바와 같이, although punctuation choices can vary with sentence length and editorial style. More important than copying every comma is keeping the dependency clear: readers should immediately see which claim the opening frame qualifies.

Beyond the Basics: Stance and Stylistic Control

Advanced writers use endings to express stance—the writer’s position toward the information—not merely politeness. -다 can present a proposition as the text’s neutral claim. -겠다 can announce the writer’s plan (살펴보겠다, “I/we will examine”), but repeated use may make the writer too visible for an impersonal research style. A noun-centered alternative such as 다음 절의 분석 대상은 …이다 can sound more detached.

Be cautious with -ㄴ 바 있다. It often sounds official and records a noteworthy prior action: 정부는 같은 방침을 발표한 바 있다 (“The government has previously announced the same policy”). In everyday experience, 한국에 가 본 적이 있다 is usually more natural than 한국에 간 바 있다. The latter frames the visit almost as a matter for the record.

Similarly, -(으)ㄹ 바가 아니다 can move beyond literal “a matter to…” and express judgment: 지금 포기할 바가 아니다 means roughly “This is no time to give up” or “We should not give up now.” 알 바 아니다 means “It is none of [someone’s] concern,” and can sound blunt. These lexicalized uses should be learned as whole expressions rather than derived word by word.

Finally, formal prose can quote speech or shift communicative setting. A report may use -다 in its analysis, reproduce an interviewee’s -요 ending inside quotation marks, and end an attached public statement with -습니다. That is controlled variation, not inconsistency: each ending belongs to a clearly identifiable voice.

Practice Tips

1. Convert by predicate type. Take ten polite sentences and rewrite them in report style. First label each predicate “action,” “descriptive,” “있다/없다,” or “이다”; then choose -ㄴ다/-는다 or -다. This prevents guessing from sound alone.
2. Run a 바 spacing check. In a newspaper or institutional report, collect examples of 바. Ask whether it names a fact or matter (space before 바) or connects two clauses as a reason or circumstance (attached -는바). Keep the whole phrase, not just the ending.
3. Edit one paragraph for register. Write a six-sentence report in -다 style, then read only the final words of each sentence. Any unexplained -요 or -습니다 will stand out. Rewrite the same content as a spoken presentation to see where -습니다 becomes the better choice.
