한다체: The Plain / Written Declarative (-ㄴ/는다) | Korean Grammar

Every other Korean speech level treats action verbs and adjectives the same way: 가요 and 좋아요 both just take 요; 갑니다 and 좋습니다 both just take 습니다. 한다체 — the plain style, also called 해라체 — is the one register where that unity breaks. Its present-tense statement forces you to know whether a word is an action verb or a descriptive verb (adjective), because the two classes take different endings: action verbs get -ㄴ다/-는다 (간다, 먹는다), while adjectives and the copula get a bare -다 that looks identical to the dictionary form (좋다, 학생이다). This is the register of books, newspapers, and diaries — the voice Korean uses when it addresses no one in particular — and it is the single best place to nail down the verb/adjective distinction that quietly runs through the whole grammar.

What 한다체 is, and where it lives

한다체 is the addressee-neutral style. The other levels are pitched at a listener — 해요체 and 합니다체 raise the person you're talking to, 해체 speaks warmly down to a familiar. 한다체 raises and lowers no one, because it presumes there is no specific listener to raise or lower. That makes it the natural default for writing and for statements aimed at the world rather than a person:

Books, novels, textbooks — narration and exposition.
Newspapers, magazines, encyclopedias — articles and entries.
Academic papers and reports — the neutral scholarly voice.
Diaries — you writing to yourself.
Generic, timeless truths — definitions and facts that hold for everyone.

지구는 태양 주위를 돈다.

jiguneun taeyang juwireul donda

The Earth revolves around the Sun. (한다체 — a timeless fact)

해는 동쪽에서 뜬다.

haeneun dongjjogeseo tteunda

The Sun rises in the east. (한다체 — generic truth)

For why Korean writing defaults to this style — the 문어체 (written style) vs 구어체 (spoken style) split — see plain style in writing and narration. This page is about the declarative form itself.

The verb/adjective split, spelled out

Here is the mechanism. In the plain present statement:

Word class	Ending	Rule	Examples
Action verb, vowel/ㄹ stem	-ㄴ다	-ㄴ다 attaches straight to the stem (ㄹ drops)	가다 → 간다 · 살다 → 산다 · 마시다 → 마신다
Action verb, consonant stem	-는다	-는다 after a final consonant	먹다 → 먹는다 · 읽다 → 읽는다 · 웃다 → 웃는다
Adjective (descriptive verb)	-다	bare -다 = the dictionary form	좋다 → 좋다 · 예쁘다 → 예쁘다 · 춥다 → 춥다
Copula 이다	-다	bare -다 = the dictionary form	학생이다 → 학생이다

The action-verb side does real work — you build a new form (간다, 먹는다) that never appears in the dictionary. The adjective and copula side does nothing visible: the plain statement of 좋다 is just 좋다, the same string you'd look up. That asymmetry is the whole reason the split is easy to miss.

Action verbs take -ㄴ다 / -는다

After a vowel stem (or a ㄹ stem, which drops its ㄹ), the ending is -ㄴ다, written into the syllable block.

그는 매일 아침 커피를 마신다.

geuneun maeil achim keopireul masinda

He drinks coffee every morning.

삼촌은 서울에 산다.

samchoneun seoure sanda

My uncle lives in Seoul. (살다 → 산다, ㄹ drops)

After a consonant stem, the ending is -는다, added as its own syllable.

학생들은 도서관에서 책을 읽는다.

haksaengdeureun doseogwaneseo chaegeul ingneunda

The students read books in the library.

아기가 엄마를 보고 웃는다.

agiga eommareul bogo unneunda

The baby looks at its mom and smiles.

Adjectives and the copula take a bare -다

Descriptive verbs — Korean's "adjectives" — make their plain statement with nothing but -다, so the sentence-final form is identical to the dictionary entry.

오늘은 날씨가 정말 춥다.

oneureun nalssiga jeongmal chupda

The weather is really cold today.

이 소설은 생각보다 재미있다.

i soseoreun saenggakboda jaemiitda

This novel is more interesting than expected.

The copula 이다 behaves like an adjective here, ending in a bare -다:

이것은 아주 중요한 문제이다.

igeoseun aju jung-yohan munjeida

This is a very important issue.

💡

Quick test: can you swap the word into "It is [adjective]" in English (cold, pretty, interesting)? Then it's a descriptive verb and its plain statement is the bare dictionary -다 (춥다, 예쁘다). Does it name an action (go, eat, read)? Then it takes -ㄴ다/-는다 (간다, 먹는다). The two existence verbs 있다/없다 side with the adjectives — their plain statement is 있다/없다, never ×있는다.

Why 한다체 is neutral, not rude

English speakers meet this "no-요" style and assume it must be the rude or casual one, since 요 reads to them as "the politeness." That instinct is wrong. 한다체 is neither polite nor intimate — it is neutral, the register with no addressee to be polite or casual toward. A textbook sentence in 한다체 isn't being rude to you; it simply isn't talking to you at all. Pointing 한다체 at a person's face in conversation is a separate, marked move — it comes out as emphatic self-narration, exclamation, or storytelling, and that spoken use has its own page, 한다체 vs 해체. In writing, though, 한다체 is the plain, correct default with no attitude attached.

The split you're really learning

The verb/adjective test you just practiced isn't a one-off quirk of this ending — it is the same test that recurs across the grammar, which is why 한다체 is worth mastering early. The identical -는 vs -(으)ㄴ divide shows up in the present attributive (a verb modifies a noun with -는: 먹는 밥 "the food [one] eats"; an adjective with -(으)ㄴ: 좋은 밥 "good food"). And it shows up again in indirect quotation, which is built directly on 한다체: "he said he goes" is 간다고 했다 (action verb, -ㄴ다고), while "he said it's good" is 좋다고 했다 (adjective, -다고).

친구가 내일 온다고 했다.

chinguga naeil ondago haetda

My friend said he's coming tomorrow. (action verb → 온다고)

사람들이 그 영화가 좋다고 했다.

saramdeuri geu yeonghwaga jotago haetda

People said the movie was good. (adjective → 좋다고)

Learn "is this an action verb or a descriptive verb?" here, in the cleanest possible frame, and you'll have already solved the attributive and the quotation the first time you meet them. The full four-mood 한다체 system builds on this same base — see 한다체 moods.

Common Mistakes

1. Writing the dictionary form 먹다 as the present statement "eats." An action verb's plain statement is 먹는다, not 먹다. Bare 먹다 is only the citation form, not a finished sentence meaning "eats."

❌ 그는 저녁에 라면을 먹다.

Wrong — an action verb needs -는다: 먹는다. 먹다 is only the dictionary form.

✅ 그는 저녁에 라면을 먹는다.

geuneun jeonyeoge ramyeoneul meongneunda

He eats ramen in the evening.

2. Adding -ㄴ다 to an adjective. Descriptive verbs take a bare -다; ×예쁜다 doesn't exist.

❌ 그 배우는 정말 예쁜다.

Wrong — 예쁘다 is an adjective; its plain form is the bare 예쁘다, never 예쁜다.

✅ 그 배우는 정말 예쁘다.

geu baeuneun jeongmal yeppeuda

That actress is really pretty.

3. Making 있다 into ×있는다. The existence verbs 있다/없다 pattern with adjectives in the statement.

❌ 냉장고에 우유가 없는다.

Wrong — 없다 takes the bare -다 here: 없다, not 없는다.

✅ 냉장고에 우유가 없다.

naengjanggoe uyuga eopda

There's no milk in the fridge.

4. Treating 한다체 as rude and avoiding it in writing. An essay or article should be in 한다체 — using 해요체 there sounds like a chatty spoken diary.

❌ 이 실험은 세 가지 결과를 보여줘요.

Wrong register for a report — 해요체 addresses a listener; written prose takes 한다체.

✅ 이 실험은 세 가지 결과를 보여준다.

Key Takeaways

한다체 (plain / 해라체) is the addressee-neutral written register — books, news, academic prose, diaries, and timeless truths.
Its present statement splits word classes: action verbs take -ㄴ다/-는다 (간다, 먹는다), adjectives and the copula take a bare -다 (좋다, 학생이다) that looks like the dictionary form.
있다/없다 side with adjectives: 있다/없다, never ×있는다.
한다체 is neutral, not rude — the absence of 요 marks "no addressee," not disrespect. Using it at a person in speech is a separate, marked move.
The same verb/adjective test drives the present attributive (-는 vs -(으)ㄴ) and indirect quotation (간다고 vs 좋다고) — master it here first.
