Korean Question Words: 누가, 뭐, 어디, 언제, 왜, 어떻게

Master korean question words — who, what, where, when, why, how — with 50+ real example sentences and K-drama lines for fluent daily talk.

Korean Question Words: 누가, 뭐, 어디, 언제, 왜, 어떻게

Asking the right questions is how real conversation starts. Once you master korean question words, you can order food, navigate Seoul, text a friend, and follow K-drama dialogue without a dictionary. This guide covers the six core question words plus bonus ones, with romanization and example sentences tailored for Arabic-speaking learners.

The Six Core Korean Question Words

English	Korean	Romanization
Who	누구 / 누가	nugu / nuga
What	뭐 / 무엇	mwo / mueot
Where	어디	eodi
When	언제	eonje
Why	왜	wae
How	어떻게	eotteoke

Step 1: Who — 누구 / 누가

누구 is "who" as object or in general. 누가 (누구 + 가) is the subject form "who" for the one doing the action.

• 이 사람은 누구예요? — Who is this person?
• 누가 왔어요? — Who came?
• 누구를 좋아해요? — Who do you like?

Step 2: What — 뭐 / 무엇

뭐 is the common spoken form; 무엇 is more formal or written.

• 이름이 뭐예요? — What is your name?
• 뭐 해요? — What are you doing?
• 뭐 먹을까요? — What should we eat?
• 무엇을 원하십니까? — What do you want? (formal)

Step 3: Where — 어디

어디 is used with particles depending on meaning.

• 어디예요? — Where is it?
• 어디 가요? — Where are you going?
• 어디에서 일해요? — Where do you work?
• 어디서 만날까요? — Where shall we meet?

Step 4: When — 언제

• 생일이 언제예요? — When is your birthday?
• 언제 와요? — When are you coming?
• 언제부터 공부했어요? — Since when have you been studying?
• 언제까지 해야 돼요? — Until when do I have to do it?

Step 5: Why — 왜

• 왜 그래요? — Why is it like that? / What is wrong?
• 왜 안 와요? — Why are you not coming?
• 왜 울어요? — Why are you crying? (classic K-drama line)

Step 6: How — 어떻게

어떻게 asks about manner or method; 얼마나 asks about quantity or degree.

• 어떻게 가요? — How do I get there?
• 어떻게 지내요? — How are you doing?
• 얼마나 걸려요? — How long does it take?
• 얼마나 매워요? — How spicy is it?

Bonus Question Words

Korean	Meaning	Example
얼마	How much (price)	얼마예요?
몇	How many (with counter)	몇 살이에요?
무슨	What kind of	무슨 영화 봐요?
어느	Which	어느 나라 사람이에요?
어떤	What kind / which sort	어떤 사람이에요?

Step 7: Building Polite and Casual Questions

Style	Example
Formal	어디 가십니까?
Polite	어디 가요?
Casual	어디 가?

Korean does not invert word order like English. You keep SOV and add a question word, with rising intonation.

Step 8: Indirect Questions

Use -는지 / -(으)ㄴ지 for embedded questions.

• 이게 뭔지 알아요? — Do you know what this is?
• 왜 그런지 몰라요 — I do not know why it is like that
• 언제 올지 모르겠어요 — I am not sure when (they) will come

Mini-Dialogue to Practice

A: 이 사람이 누구예요? B: 제 친구예요. 이름은 지민이에요. A: 어디에서 만났어요? B: 학원에서 만났어요. A: 언제부터 알았어요? B: 작년부터요.

Translation: A: Who is this? B: He is my friend. His name is Jimin. A: Where did you meet? B: We met at the academy. A: Since when have you known him? B: Since last year.

Tips to Sound Natural

1. Drop 저는 / 당신은 in most questions — context is enough.
2. Use 뭐 in speaking, 무엇 mostly in writing.
3. Learn 누가 vs 누구 — they are not interchangeable.
4. Rise your intonation at the end for yes/no questions.
5. Watch K-drama scenes and pause each time a question word appears.

Common Mistakes

• Translating "why" as 왜 in every context; sometimes 어째서 fits better in literary style.
• Using 어디 without a particle when the verb requires one (가요 vs 에서 일해요).
• Forgetting that 몇 requires a counter (몇 명, 몇 시).

Frequently Asked Questions

How long before I see real progress with korean question words?

Many beginners notice progress with regular daily practice. Many intermediate learners hit a plateau, which is where structured courses can make the biggest difference.

What resources pair best with this guide?

Combine this article with our textbook, a daily journaling habit, and one K-drama scene per day. That three-stack covers reading, writing, and listening at the same time.

Should I focus on speaking or grammar first?

Grammar gives you the scaffolding, but speaking forces the brain to retrieve language under pressure. Beginners should do both — 30 minutes of grammar, 15 minutes of shadowing speech — every single day.
