Asking Questions (Basic Formation)
Grammar Rule in 30 Seconds
In Korean, you turn a statement into a question simply by changing the ending or using a question mark in writing.
- Use the '-(으)ㅂ니까?' ending for formal questions: '밥을 먹습니까?' (Do you eat?)
- Use the '-아요/어요?' ending for polite questions: '밥을 먹어요?' (Do you eat?)
- Use the '-니?' ending for casual questions: '밥 먹니?' (Do you eat?)
Overview
Asking questions in Korean fundamentally differs from English, primarily due to Korean’s Subject-Object-Verb (SOV) word order and its heavy reliance on verb endings to convey grammatical mood, including interrogation. Unlike English, which often rearranges word order or inserts auxiliary verbs (e.g., 'do,' 'is') to form questions, Korean maintains its basic sentence structure. The interrogative nature of a sentence is signaled either by a specific verb ending or, in polite informal speech, by rising intonation at the end of the sentence.
This system allows for remarkable consistency. For example, a statement like 밥 먹어요 (I eat rice) can become 밥 먹어요? (Are you eating rice?) simply by changing the intonation. This efficiency means learners can focus on mastering core sentence structures rather than complex transformations.
Understanding this principle is crucial, as it underpins much of Korean grammar.
How This Grammar Works
해요체 (-아요/어요), a question is distinguished from a statement almost exclusively by rising intonation. A flat or falling intonation indicates a declarative statement, while a rising intonation signals a question. For instance, 한국 사람이에요 (I am Korean) is a statement.한국 사람이에요? (Are you Korean?) becomes a question with the same words but a higher pitch at the end.합쇼체 (-ㅂ니다/습니다), the verb ending itself changes. Declarative sentences end with -ㅂ니다 or -습니다, but interrogative sentences conclude with -ㅂ니까 or -습니까. This explicit grammatical marker makes intonation less critical for indicating a question in formal contexts, though a slightly rising tone is still natural.갑니다 (I go) becomes 갑니까? (Are you going?).Word Order Rules
민지가 사과를 먹어요 (Minji eats an apple). If you want to ask who eats the apple, 누구 (who) replaces 민지 (Minji), maintaining the subject position: 누가 사과를 먹어요? (Who eats the apple?). If you want to ask what Minji eats, 무엇 (what) or 뭐 (its contracted form) replaces 사과 (apple), keeping the object position: 민지가 뭐를 먹어요? (What does Minji eat?).수지가 학교에 가요. (Suzy goes to school.) | 수지가 어디에 가요? (Where does Suzy go?) |지민이 커피를 마셨어요. (Jimin drank coffee.) | 지민이 무엇을 마셨어요? (What did Jimin drink?) |학교 (school) and 어디 (where) both precede the verb 가요, and 커피 (coffee) and 무엇 (what) both precede 마셨어요. The placement of the interrogative word corresponds directly to the grammatical role of the information being sought.Formation Pattern
해요체) and Formal Polite (합쇼체).
해요체) Questions:
해요체 are formed by using the same verb ending as declarative statements (-아요/어요) but with a rising intonation at the end of the sentence.
-아요/어요 + Rising Intonation (?)
-아요 when the last vowel of the verb stem is ㅏ or ㅗ (e.g., 가다 (to go) → 가 + 아요 → 가요).
-어요 for all other vowel endings (e.g., 먹다 (to eat) → 먹 + 어요 → 먹어요).
하다 change to 해요 (e.g., 공부하다 (to study) → 공부해요).
해요체) | Interrogative (해요체) | English (Literal) |
가다 | 가요. (I go.) | 가요? (Are you going?) | Go? |
먹다 | 먹어요. (I eat.) | 먹어요? (Are you eating?) | Eat? |
읽다 | 읽어요. (I read.) | 읽어요? (Are you reading?) | Read? |
하다 | 해요. (I do.) | 해요? (Are you doing?) | Do? |
커피 마셔요? (Are you drinking coffee?) — distinguished from 커피 마셔요. (I'm drinking coffee.) solely by your tone of voice.
합쇼체) Questions:
해요체, 합쇼체 uses distinct question endings.
-ㅂ니까/습니까
-ㅂ니까 (e.g., 가다 (to go) → 가 + ㅂ니까 → 갑니까?).
-습니까 (e.g., 먹다 (to eat) → 먹 + 습니까 → 먹습니까?).
합쇼체) | Interrogative (합쇼체) | English (Literal) |
가다 | 갑니다. (I go.) | 갑니까? (Do you go?) | Go? |
먹다 | 먹습니다. (I eat.) | 먹습니까? (Do you eat?) | Eat? |
읽다 | 읽습니다. (I read.) | 읽습니까? (Do you read?) | Read? |
하다 | 합니다. (I do.) | 합니까? (Do you do?) | Do? |
주문하시겠습니까? (Would you like to order? - formal service context).
해요체) | English (Literal) |
누구 (nugu) | Who | 누가 왔어요? | Who came? |\
무엇 (mueot) / 뭐 (mwo) | What | 뭐 먹고 싶어요? | What do you want to eat? |\
어디 (eodi) | Where | 어디에 가요? | Where are you going? |\
언제 (eonje) | When | 언제 만나요? | When shall we meet? |\
왜 (wae) | Why | 왜 안 왔어요? | Why didn't you come? |\
어떻게 (eotteoke) | How | 어떻게 만들어요? | How do you make it? |\
몇 (myeot) | How many | 몇 시예요? | What time is it? (Lit: How many o'clock?) |\
얼마 (eolma) | How much | 이거 얼마예요? | How much is this? |
민지가 어디에 가요? (Where is Minji going?) is correct, with 어디에 replacing the location. Avoid placing all interrogatives at the beginning if they modify other parts of the sentence.
When To Use It
해요체 (Polite Informal) for most everyday situations:- With friends, colleagues, or acquaintances of similar age or status:
점심 먹었어요?(Did you eat lunch?). - With strangers in general public settings (shops, restaurants, public transport):
이거 얼마예요?(How much is this?). - When addressing elders or superiors in a respectful, but not overly formal, manner if the relationship allows (e.g., a professor you know well):
잘 지내셨어요?(Have you been well?). - This is your default question form at the A1 level. Most interactions you will have as a beginner will comfortably fit into this category.
합쇼체 (Formal Polite) for highly formal or public contexts:- In business or professional settings, especially during initial introductions or meetings with superiors:
성함이 어떻게 되십니까?(What is your name? - highly formal). - When addressing an audience in a lecture, presentation, or news report:
다음 소식입니다. 현재 상황은 어떻습니까?(Next news. What is the current situation?). - In service industries (e.g., flight attendants, customer service representatives) when addressing customers:
무엇을 도와드릴까요?(How may I help you?). - This form conveys a high degree of respect and formality. While essential to recognize, learners at A1 might not use it extensively in active conversation until later stages.
해요체 or 합쇼체 endings, though 해요체 is more common for A1 learners.오늘 뭐 해요?(What are you doing today? -해요체with뭐).회의는 언제 시작합니까?(When does the meeting start? -합쇼체with언제).
해요체 and adjust as you become more familiar with social cues.Common Mistakes
- Error: Attempting to insert a Korean equivalent for English auxiliary verbs like 'do' or 'is' at the beginning of a question. For example, trying to say something like
해요 당신은 좋아해요?for

Smart Tips
Use the polite -아요/어요 form; it is safe in almost all situations.
Put the question word (like 'what' or 'where') right before the verb.
Use formal -ㅂ니까 to show high respect.
Use the casual -니 form only with close friends.
Pronunciation
Rising Intonation
Raise your pitch at the end of the sentence to signal a question.
Question Pitch
어디 가요? (↗)
Signals a polite question.
Memorize It
Mnemonic
Think of the question mark as a hook that pulls the verb up into a question.
Visual Association
Imagine a fishing rod where the hook is the question mark, catching the verb and lifting it high into the air.
Rhyme
When you ask, don't be shy, just raise your pitch and say -yo or -ni!
Story
Min-su is at a cafe. He looks at the menu and asks, '이거 맛있어요?' (Is this delicious?). The waiter smiles and says, '네, 맛있어요.' (Yes, it is). Min-su then asks, '얼마예요?' (How much is it?).
Word Web
Challenge
Ask 3 people today: '오늘 날씨가 좋아요?' (Is the weather good today?)
Cultural Notes
Politeness is essential. Always use -yo with people you don't know well.
They often use different intonation and endings like -na.
Formal -ㅂ니까 is expected in meetings.
Korean interrogative endings evolved from ancient verb suffixes that indicated the speaker's intent.
