TL;DR 🦄
- ❓ -(으)ㄴ/는가? [-(eu)n/neun-ga] is a formal, reflective question ending often used in essays, speeches, titles, and big “think with me” questions.
- 🧠 In a 수사 의문문 [su-sa ui-mun-mun] — a rhetorical question — the speaker is usually not waiting for an answer. The question points toward a strong idea.
- ✍️ It feels more written, serious, or philosophical than everyday -아요/어요? [-a-yo/eo-yo?] or polite -(으)ㄴ/는가요? [-(eu)n/neun-ga-yo?].
🎧 Iru Helper Note — Use Korean Helper Widgets to hear sentences like 우리는 왜 같은 실수를 반복하는가? [u-ri-neun wae ga-teun sil-su-reul ban-bo-ka-neun-ga] and 진짜 중요한 것은 무엇인가? [jin-jja jung-yo-han geo-seun mu-eo-sin-ga]. Listen for the thoughtful “essay question” rhythm. 🎧
🌈 The Big Picture
-(으)ㄴ/는가? is the grammar of serious questions: reflection essays, debate openings, presentation titles, philosophical thoughts, and dramatic “Are we really doing this?” moments. It is not usually the first ending you use when ordering coffee. ☕
A normal question asks for information. A rhetorical question often guides the listener toward a point:
- 우리는 왜 같은 실수를 반복하는가?
[u-ri-neun wae ga-teun sil-su-reul ban-bo-ka-neun-ga] — Why do we repeat the same mistake? 🔁
우리 = we/us; 왜 = why; 같다 = to be same; 실수 = mistake; 반복하다 = to repeat.
- 진짜 중요한 것은 무엇인가?
[jin-jja jung-yo-han geo-seun mu-eo-sin-ga] — What is truly important? 🧭
진짜 = truly / real; 중요하다 = to be important; 것 = thing; 무엇 = what.
In Korean, this ending can sound polished, written, self-directed, or public-facing. It is excellent for advanced grammar because it teaches both form and tone — tiny ending, huge attitude. 🎭
🎨 The Core -(으)ㄴ/는가? Family
1. Action verbs: -는가?
Use -는가? for present action verbs.
- 반복하다 [ban-bo-ka-da] — to repeat → 반복하는가? [ban-bo-ka-neun-ga] — does one repeat? / do we repeat?
- 해결하다 [hae-gyeol-ha-da] — to solve → 해결하는가? [hae-gyeol-ha-neun-ga] — does one solve?
- 행동하다 [haeng-dong-ha-da] — to act → 행동하는가? [haeng-dong-ha-neun-ga] — does one act?
- 침묵하다 [chim-mu-ka-da] — to stay silent → 침묵하는가? [chim-mu-ka-neun-ga] — does one stay silent?
2. Descriptive verbs / adjectives: -(으)ㄴ가?
Use -ㄴ가? after vowel-ending adjective stems and -은가? after consonant-ending adjective stems.
- 중요하다 [jung-yo-ha-da] — to be important → 중요한가? [jung-yo-han-ga] — is it important?
- 충분하다 [chung-bun-ha-da] — to be enough → 충분한가? [chung-bun-han-ga] — is it enough?
- 옳다 [ol-ta] — to be right/correct → 옳은가? [o-reun-ga] — is it right?
- 자유롭다 [ja-yu-rop-da] — to be free → 자유로운가? [ja-yu-ro-un-ga] — is it free?
3. Nouns with 이다: 인가?
Use noun + 인가?.
- 문제 [mun-je] — problem → 문제인가? [mun-je-in-ga] — is it a problem?
- 답 [dap] — answer → 답인가? [da-bin-ga] — is it the answer?
- 선택 [seon-taek] — choice → 선택인가? [seon-tae-gin-ga] — is it a choice?
4. Past and future
- Past action/state often uses -았/었는가?: 우리는 무엇을 배웠는가? [u-ri-neun mu-eo-seul bae-wot-neun-ga] — What did we learn? 📚
- Future/intention often uses -(으)ㄹ 것인가?: 우리는 어떤 미래를 만들 것인가? [u-ri-neun eo-tteon mi-rae-reul man-deul geo-sin-ga] — What kind of future will we make? 🌱
🛠️ How They Work in a Sentence
-(으)ㄴ/는가? shines when the question is bigger than the answer. It makes the sentence feel like an essay prompt, a debate hook, or a mirror held up to the reader. 🪞
- 이 방법이 정말 문제를 해결하는가?
[i bang-beo-bi jeong-mal mun-je-reul hae-gyeol-ha-neun-ga]
Does this method really solve the problem? 🧰
이 = this; 방법 = method; 정말 = really; 문제 = problem; 해결하다 = to solve.
- 지금 우리의 침묵은 충분한가?
[ji-geum u-ri-ui chim-mu-geun chung-bun-han-ga]
Is our silence now enough? 🤐
지금 = now; 우리의 = our; 침묵 = silence; 충분하다 = to be enough.
- 우리는 어떤 사회를 만들 것인가?
[u-ri-neun eo-tteon sa-hoe-reul man-deul geo-sin-ga]
What kind of society will we make? 🏙️
어떤 = what kind of; 사회 = society; 만들다 = to make.
🧩 General Formation Rule
Present action verbs
Verb stem + -는가?
- 반복하다 → 반복하는가?
- 해결하다 → 해결하는가?
- 말하다 → 말하는가?
- 듣다 → 듣는가?
Descriptive verbs / adjectives
Adjective stem + -(으)ㄴ가?
- 중요하다 → 중요한가?
- 충분하다 → 충분한가?
- 옳다 → 옳은가?
- 자유롭다 → 자유로운가?
Nouns
Noun + 인가?
- 문제 → 문제인가?
- 답 → 답인가?
- 선택 → 선택인가?
Rhetorical force
The grammar alone does not automatically make a rhetorical question. Context does the magic:
- 이것이 답인가? can be a real question in writing.
- 이것이 정말 답인가? often sounds reflective or skeptical: “Is this really the answer?” 🧐
- 누가 책임에서 자유로운가? often implies “No one is free from responsibility.” ⚖️
📚 Cross-check note
This lesson was checked against korean.go.kr. Their grammar guidance describes -ㄴ가, -은가, and -는가 as question endings, and their dictionary definition of 수사 의문문 explains that it has question form but does not require an answer and implies a strong positive or negative statement. ✅
🪞 Synonym Alert
These endings overlap, but the vibe changes:
- -(으)ㄴ/는가? → formal, written, reflective, essay-like: 무엇이 중요한가? = What is important?
- -(으)ㄴ/는가요? → polite and softer to another person: 무엇이 중요한가요? = What is important? / May I ask what is important?
- -지 않겠어요? → polite rhetorical agreement-seeking: 중요하지 않겠어요? = Wouldn’t it be important?
- -나? → casual/self-directed or plain wondering: 중요한가? can be more formal than 중요하나? depending on context.
⚠️ Pitfalls to Dodge
- ❌ Using -(으)ㄴ/는가? for casual daily questions → ✅ use -아요/어요? or -(으)ㄴ/는가요? in ordinary polite conversation.
- ❌ Assuming every -(으)ㄴ/는가? sentence is rhetorical → ✅ context decides whether it asks, reflects, or argues.
- ❌ 중요하는가? → ✅ 중요한가?. 중요하다 is descriptive, so use -ㄴ가?.
- ❌ 해결한가? for present action → ✅ 해결하는가?. Present action verbs use -는가?.
- ❌ 문제는가? → ✅ 문제인가?. Nouns use 인가?.
🎉 You now have a polished rhetorical-question tool: 무엇인가?, 왜 반복하는가?, 정말 충분한가?. Use it when your Korean needs a little courtroom spotlight and a tiny philosopher cape. 🧠⚖️
