무슨 What Kind of: Meaning, Rules and Examples

What you'll learn

• Place 무슨 correctly before a noun, with no particle between them.
• Ask about days, topics and meanings with 무슨 요일, 무슨 일 and 무슨 뜻.
• Choose between 무슨 and 뭐, and say why in one sentence.
• Recognise the rhetorical uses of 무슨, such as 무슨 소리예요?
• Fix the most common mistake: using 무슨 without a noun.

Before you start: you should know that Korean attaches particles such as 을/를 to nouns and that the verb comes last. If not, read Korean sentence structure first. Audio plays only when you press a button.

What Does 무슨 What Kind of Mean?

무슨 is a question determiner (관형사, gwanhyeongsa): a word that modifies a noun without taking any ending. It asks "what" or "what kind of" about the noun that comes right after it. Because it modifies a noun, 무슨 can never stand by itself, and it never takes a particle such as 이/가 or 을/를.

A determiner is different from a pronoun. A pronoun like 뭐 replaces a noun, while a determiner like 무슨 sits next to a noun and leaves the noun in the sentence. The noun then takes its own particle: 무슨 음식을, not 무슨을 음식.

A First Example

Two annotated sentences show the pattern.

• 무슨 음식을 좋아해요? (museun eumsigeul joahaeyo?) [무슨 음시글 조아해요] = "What kind of food do you like?" The parts are 무슨 (what kind of), 음식을 (food, object), 좋아해요 (like, polite ending).
• 무슨 일이에요? (museun irieyo?) [무슨 니리에요] = "What is the matter?" or "What is it about?" The parts are 무슨 (what), 일 (matter, work), 이에요 (is).

In both sentences a noun follows 무슨 directly. The rule behind this is short, and the next section states it with a table of the nouns learners use most.

How Does 무슨 What Kind of Work?

Put 무슨 immediately before a noun, leave out any particle between the two, and then add the particle and verb you would use for the noun in a normal sentence. The question has the same shape as the statement it replaces. If the answer is "Korean food" (한식), the statement is 한식을 좋아해요, and the question swaps 한식 for 무슨 음식.

Pronunciation changes when the noun starts with an i or y sound (이, 야, 여, 요, 유). After 무슨, which ends in ㄴ, a noun such as 일 or 요일 usually gets an extra ㄴ sound when the two words are said together, so 무슨 일 is spoken [무슨 닐] and 무슨 요일 [무슨 뇨일]. Standard pronunciation rules (국립국어원 표준 발음법) describe this "ㄴ insertion." You do not need to write it: spell the words normally and let your mouth add the sound.

The table lists the nouns that follow 무슨 most often. Each row gives the full phrase, its meaning and a model sentence.

The table shows that 무슨 works with food, events, days and ideas. One step-by-step example shows how to turn a plain sentence into a 무슨 question.

How Do You Build a Question with 무슨 Step by Step?

You build a 무슨 question by finding the noun you want to ask about and putting 무슨 in front of it. Follow the steps with the sentence "I read a book."

1. Start with the statement. 저는 책을 읽어요. (jeoneun chaegeul ilgeoyo.) [저는 채글 일거요] = "I read a book." The noun is 책.
2. Find the part you want to ask about. You want to ask about the kind of book, not whether you read one.
3. Put 무슨 before the noun. 책 becomes 무슨 책. Keep the particle on the noun: 무슨 책을.
4. Drop the subject. Ask about the listener without saying "you": 무슨 책을 읽어요?
5. Say it as a question. 무슨 책을 읽어요? (museun chaegeul ilgeoyo?) = "What book are you reading?" The question word already marks the question, so the end often falls rather than rises.

You will know it worked when the noun still carries its own particle and 무슨 has none of its own. The common slip is putting 이/가 on 무슨 itself, as in 무슨이 책이에요, which Korean never says. The same method works for 무슨 영화를 봐요? ("What movie are you watching?") or 무슨 노래를 들어요? ("What song are you listening to?"). Here is a short exchange that uses the pattern twice:

• A: 주말에 무슨 영화를 봐요? (jumare museun yeonghwareul bwayo?) = "What movie are you watching on the weekend?"
• B: 한국 영화를 봐요. 무슨 영화를 좋아해요? (hanguk yeonghwareul bwayo. museun yeonghwareul joahaeyo?) = "I'm watching a Korean movie. What kind of movies do you like?"

Each question keeps the noun 영화 and its particle 를, and only the first word changes. A second question follows: how does 무슨 compare with other question words?

How Is 무슨 Different from 뭐 and 어떤?

무슨 needs a noun right after it, 뭐 stands alone, and 어떤 also needs a noun but asks about quality or type. The position test settles most cases: a noun next to the question word means 무슨 or 어떤, and no noun means 뭐.

The two replies differ. 뭐 봐요? invites a title: "I'm watching Parasite." 무슨 영화를 봐요? invites the same title or a type such as "an action movie." In everyday speech, 무슨 and 어떤 overlap a lot, and a learner who swaps them is usually still understood. The 뭐 무엇 what in korean lesson covers the stand-alone word, and 어떤 what kind of which covers the sibling determiner. The full three-way comparison is in 무슨 vs 어떤 vs 어느.

When Do You Use 무슨, and When Not?

Use 무슨 when you ask about the identity or topic of a noun, and avoid it when you need a number or a choice from a known set. Several fixed uses are worth learning as whole phrases.

• Days of the week. 무슨 요일이에요? is the standard question for "What day is it?" The answer is 월요일이에요 ("It's Monday"). For the date of the month, Korean uses 며칠 instead (오늘 며칠이에요?).
• Meaning. 무슨 뜻이에요? ("What does it mean?") is one of the most useful classroom questions. Add the word before it: 이 단어는 무슨 뜻이에요?
• "Is something wrong?" 무슨 일 있어요? (museun il isseoyo?) [무슨 닐 이써요] with a rising tone means "Is something wrong?" or "Did something happen?" The same words with a falling tone ask "What is going on?"
• Disbelief. 무슨 소리예요? (museun soriyeyo?) means "What are you talking about?" and 무슨 말이에요? means "What do you mean?" These are not neutral questions. They show surprise or disagreement, so use them with friends rather than with a boss.
• Not for time or number. To ask the hour, say 몇 시예요?, not 무슨 시예요?. See 몇 how many in korean for the counting questions.
• Not for choices. When you point at two or three items and ask which, use 어느 which in korean.

An honest limit: this lesson treats 무슨 and 어떤 as close neighbours and gives a working rule, not a strict boundary. Native speakers swap them often in questions about kinds, and dictionaries list overlapping senses. Learners who follow the position rule above will be correct and natural in the large majority of everyday questions. The most frequent errors come from breaking that position rule.

What Mistakes Do Learners Make with 무슨?

Learners most often drop the noun or add a particle in the wrong place. Four mistakes appear again and again, and each has a quick repair.

1. Using 무슨 without a noun. 무슨 먹어요? is wrong because 무슨 has nothing to modify. Say 뭐 먹어요? ("What are you eating?") or 무슨 음식을 먹어요? ("What food are you eating?").
2. Putting a particle on 무슨. 무슨이, 무슨을 and 무슨은 do not exist. The noun after 무슨 carries the particle: 무슨 음식이 맛있어요?
3. Using 무슨 for time and number. 무슨 시예요? and 무슨 명이에요? are wrong. Use 몇 시예요? and 몇 명이에요?, which ask for numbers.
4. Using 무슨 for a known choice. If a menu lies on the table and you ask 무슨 음식이 맛있어요?, the question sounds open-ended. Ask 어느 음식이 맛있어요? ("Which dish is tasty?") to pick from the menu.

Use this checklist when a 무슨 sentence feels wrong: Is there a noun right after 무슨? Is the particle on the noun, not on 무슨? Does the question ask for a kind or topic, not a number or a choice? The practice below tests these three checks.

Practice and Answers

Try the four items before you read the answer key. Cover the answers with your hand.

1. Choose the form. Complete: ___ 음식을 좋아해요? (뭐 / 무슨)
2. Fix the error. A learner asks 무슨 먹어요? What are two ways to repair it?
3. Translate. "What day is it today?"
4. Write your own. Write one question with 무슨 and the noun 영화, and one with 무슨 and the noun 노래.

Answer key

1. 무슨. The noun 음식 follows, so the determiner 무슨 is needed: 무슨 음식을 좋아해요?
2. Add a noun: 무슨 음식을 먹어요? Or use the stand-alone word: 뭐 먹어요? Either one repairs the missing noun.
3. 오늘 무슨 요일이에요? (oneul museun yoirieyo?) The answer might be 오늘은 금요일이에요.
4. Answers vary. Check that 무슨 sits right before the noun and the noun has its own particle. Examples: 무슨 영화를 좋아해요? and 무슨 노래를 들어요?.

Remember this rule of thumb: 무슨 plus a noun, never 무슨 alone. If no noun follows, reach for 뭐.

What Should You Learn Next after 무슨 What Kind Of?

After 무슨 what kind of, study the neighbouring determiners and then the other question words. This lesson covers the pattern before a noun and does not teach the full contrast with 어떤 and 어느. Those live on their own pages.

1. Start with 뭐 무엇 what in korean if you skipped the stand-alone "what."
2. Continue with 어떤 what kind of which, which covers quality and type.
3. Learn 어느 which in korean for choices from a known set, then read 무슨 vs 어떤 vs 어느.
4. Practise questions that need no question word in yes no questions in korean.
5. Return to Korean questions to see every lesson in the set.

With these steps, 무슨 what kind of becomes automatic: find the noun, put 무슨 in front of it, and let the noun keep its own particle.

Frequently Asked Questions

What Does 무슨 Mean in Korean?

무슨 means "what" or "what kind of" and always comes before a noun. 무슨 음식 is "what food," and 무슨 일 is "what matter." It asks about the identity, topic or type of that noun. It cannot stand alone, so a question like 무슨 먹어요? is incorrect without a noun after it.

Can 무슨 Take a Particle Like 이 or 을?

No. 무슨 is a determiner, so it never takes a particle. The noun after it takes the particle instead: 무슨 음식을 좋아해요? has 을 on 음식. If you find yourself writing 무슨이 or 무슨을, delete the particle and move it to the noun that follows 무슨.

How Do I Ask the Day of the Week in Korean?

Ask 무슨 요일이에요?, which means "What day of the week is it?" Add 오늘 for "today": 오늘 무슨 요일이에요? A reply is 오늘은 수요일이에요. The date of the month is a different question, 오늘 며칠이에요?, which uses 며칠 and not 무슨.

Is 무슨 일이에요 Always a Polite Question?

It is polite in form, since 요 is a polite ending. The meaning is open, "What is the matter?", and tone decides how it lands. With a rising tone and a caring face it shows concern. Said sharply it can sound impatient. Adding 괜찮아요? ("Are you OK?") makes it warmer.

Can I Use 무슨 and 어떤 Interchangeably?

Often yes, for questions like 무슨 영화 and 어떤 영화. 무슨 leans toward identity or topic, and 어떤 leans toward type or quality. Native speakers swap them freely in many cases, so a mix-up rarely causes confusion. For a pure choice from a known set, use 어느 instead.
