The Plain/Written Present -ㄴ다/는다 (한다체)

Open any Korean novel, newspaper, diary entry, or news headline and you will not find 해요 or 합니다 at the end of the sentences. You will find 간다, 먹는다, 좋다 — the plain present, or 한다체. This is the neutral, impersonal, "written-default" style: it addresses no one in particular, so it carries no politeness toward a listener. That is exactly why it fits print, narration, and private note-taking, and also why it can sound blunt or emphatic when used out loud. This page teaches how to build it — and shows you that its class-splitting shape is secretly the sharpest diagnostic in the whole verb system.

Action verbs: add -ㄴ다 or -는다

For action verbs (동사 — verbs of doing), the plain present is not the dictionary form. You attach a suffix to the stem, and which one depends on how the stem ends:

• Vowel-final stem → -ㄴ다 (fused onto the stem's last block): 가다 → 간다, 오다 → 온다, 보다 → 본다, 자다 → 잔다.
• ㄹ-final stem → -ㄴ다, and the ㄹ drops: 살다 → 산다, 알다 → 안다, 놀다 → 논다.
• Other consonant-final stem → -는다: 먹다 → 먹는다, 읽다 → 읽는다, 받다 → 받는다.

Note the pronunciation of the consonant-stem forms: the ㄴ of -는다 triggers nasalization, so 먹는다 is said [멍는다] and 읽는다 is said [잉는다]. You still write 먹는다, 읽는다 — the spelling is fixed, the sound changes. (See nasalization before a nasal.)

Descriptive verbs and the copula: stay bare -다

Descriptive verbs (형용사 — what English calls adjectives) do not take -ㄴ다/는다. Their plain present is the bare dictionary form -다. The copula 이다 behaves the same way — it stays 이다.

So a plain-present narrative sentence can end in 간다 (action verb, suffixed) right next to one ending in 좋다 (adjective, bare). This is not an inconsistency — it is the grammar telling you which kind of word each one is.

The hidden diagnostic: action vs descriptive verb

This asymmetry is the single cleanest test for the action-vs-descriptive distinction — a distinction that governs half of Korean grammar (which attributive ending a word takes, whether it can be commanded, and more). Apply the plain present:

• If the word becomes X는다 / X-ㄴ다, it is an action verb. (먹다 → 먹는다 ✓ action; 가다 → 간다 ✓ action.)
• If it stays plain X다, it is a descriptive verb (adjective). (좋다 → 좋다, unchanged → adjective; 크다 → 크다, unchanged → adjective.)

Try it on 있다 and 없다, the tricky existence words: you can say 있는다? No — but you can say 재미있다 stays 재미있다. These pattern as descriptive here, which is why their plain present is 있다/없다, not ×있는다. (Their attributive is the exception that keeps learners up at night — covered separately.)

Register: written-neutral, not rude — but not for polite chat

한다체 is the default of the printed page. It is what you write in:

• Books and fiction — all narration.
• Newspapers and headlines — 대통령이 오늘 방문한다 ("The president visits today").
• Diaries, notes, and internal monologue — 오늘은 정말 피곤하다 ("So tired today").
• Blunt or emphatic spoken assertions — thrown out loud, it sounds forceful or declarative rather than conversational.

What it is not is polite conversation. When you are actually talking to someone you owe politeness, you use 해요체 (해요) or 합니다체 (합니다), never 한다체. Dropping into 간다 with a stranger doesn't read as neutral — it reads as blunt or oddly literary, because you've stripped out the listener-politeness the situation calls for. (For the intimate spoken plain style used with close friends, that's a different register — 반말/해체 — which for statements uses -아/어, not -ㄴ다.)

Common Mistakes

1. Attaching -ㄴ다 to an adjective. Adjectives already predicate in the bare -다 form; there is no slot for -ㄴ다.

2. Adding -ㄴ다 to another adjective by analogy. Same rule: 크다, 좋다, 예쁘다 never take the suffix.

3. Using -는다 on a vowel stem. Vowel-final action stems take -ㄴ다, not -는다.

4. Forgetting to drop ㄹ. ㄹ-final stems lose the ㄹ before -ㄴ다.

5. Using 한다체 in polite conversation. To someone you'd address with 요, the plain style sounds blunt or impersonal.

Key Takeaways

• 한다체 is the written-neutral / impersonal present: books, news, diaries, narration, and blunt spoken assertions.
• Action verbs take a suffix: vowel/ㄹ stems → -ㄴ다 (간다, 산다), other consonant stems → -는다 (먹는다, 읽는다). ㄹ drops.
• Adjectives and the copula stay bare -다 (좋다, 파랗다, 학생이다).
• That split is the cleanest test for action vs descriptive verbs: -는다/ㄴ다 fits → action verb; only -다 fits → adjective.
• Never use 한다체 where politeness is owed — use 해요체 or 합니다체 instead.
