The 쯤 about particle is the Korean ending that attaches to a time, an amount or a place word to make it approximate: "about" or "around". Say 세 시쯤 만나요 for "Let us meet around three." After this lesson you can use 쯤 correctly, choose it over 정도, 경 and 약, and avoid its most common mistake.
What you'll learn
- Attach 쯤 to a time, an amount, a place or a question word to make it approximate.
- Choose among 쯤, 정도, 경 and 약 by looking at the word and the register.
- Combine 쯤 with 에 in the right order.
- Diagnose the error in 정확히 세 시쯤 만나요 and fix it.
Before you start: you can say clock times and simple amounts, as in the lesson on the time particle 에, and you know that a particle attaches to the end of a word. Estimated time: 15 minutes.
What Does the 쯤 about Particle Mean?
The 쯤 about particle means "about", "around" or "roughly". It tells the listener that the figure before it is an estimate, not an exact value. A particle (조사, josa) is a short ending glued to a word to show its job in the sentence, a little like a label on a box. Strictly speaking, 쯤 is a suffix (접미사) that behaves like a particle, and Korean grammar books list it together with the particles.
English handles approximation with separate words such as "about", "around" and "or so", which sit before or after the number. Korean fixes the marker to the end of the word: 세 시쯤 is "three o'clock-ish". The speaker admits that the exact figure is uncertain, and the listener knows not to expect precision. This makes 쯤 useful in plans, travel times and prices, where nobody expects an exact answer.
A First Example
The two sentences below put 쯤 on a clock time and on a length of time. Read the Korean first, then the romanization, then the meaning.
- 세 시쯤 만나요. (se sijjeum mannayo) [세 시쯤 만나요] = "Let us meet around three." Word by word: 세 시 (three o'clock) + 쯤 (about) + 만나요 (meet).
- 한 달쯤 걸려요. (han daljjeum geollyeoyo) [한 달쯤 걸려요] = "It takes about a month." Word by word: 한 달 (one month) + 쯤 (about) + 걸려요 (it takes).
Notice two things. First, 쯤 is written without a space and starts with the tense consonant ㅉ, which is said with a tight throat and no puff of air. Second, the first sentence uses 쯤 on a point in time and the second uses it on a length of time, so the same particle covers both. With the meaning in place, the next section shows how to build the phrase.
How Does the 쯤 about Particle Work?
The 쯤 about particle has one form, and it follows the time or amount expression it softens. It does not change after a vowel or a consonant, and it never attaches to a verb.
- Pick the time, amount, place or question word: 세 시, 한 달, 열 명, 언제, 이.
- Attach 쯤 directly to it, with no space: 세 시쯤.
- Add a verb or a copula.
- Put the verb last.
Three things can come before 쯤. A time point is a clock time, a date or a day word, such as 세 시, 다음 주 or 금요일. An amount is a number plus a counter, such as 두 시간, 열 명 or 만 원. A pointing or question word is 이, 그, 저, 언제, 어디, 얼마 or 몇 시. The question-word use is very common in speech: 언제쯤 도착해요? (eonjejjeum dochakaeyo) [언제쯤 도차캐요] means "About when do you arrive?"
Pattern Table
The table lists common expressions with 쯤. Brackets show how the phrase sounds where it differs from the spelling.
| Type | Expression + 쯤 | Meaning |
|---|---|---|
| Clock time | 세 시쯤 | around three o'clock |
| Day | 금요일쯤 | around Friday |
| Length of time | 한 달쯤 | about a month |
| Length of time | 두 시간쯤 | about two hours |
| People | 열 명쯤 | about ten people |
| Money | 만 원쯤 | about 10,000 won |
| Question word | 언제쯤 | about when |
| Question word | 몇 시쯤 | about what time |
| Place | 어디쯤 | about where |
| Pointing word | 이쯤 | about here, about this much |
The table shows that the particle is the same in every row. The pronunciation of the whole phrase follows the usual sound rules, so 열 명쯤 sounds like [열 명쯤] and 몇 시쯤 sounds like [멷씨쯤]. The form rule is complete, so the next section builds one full sentence from scratch.
Worked Example, Step by Step
This worked example builds 세 시쯤 만나요 ("Let us meet around three") from its parts. Each step names one decision, so you can repeat the process with any time or amount.
- Choose the figure. You want to propose a meeting time that is not exact, so the figure is 세 시 (three o'clock).
- Check that the figure is a time or amount. 세 시 is a clock time, so it can take 쯤.
- Attach 쯤. Write 세 시 and add 쯤 directly: 세 시쯤. A space belongs between 세 and 시, but none before 쯤.
- Decide about 에. The meeting happens at a point in time, so 에 is possible after 쯤: 세 시쯤에 만나요. In everyday speech, 에 is often dropped: 세 시쯤 만나요.
- Choose the verb. You want "meet", which is 만나다. The polite present is 만나요.
- Put the verb last. Korean ends with the predicate: 세 시쯤 만나요.
- Leave out what is obvious. "We" is clear from the context, so no subject is needed.
- Say it aloud. The phrase is [세 시쯤 만나요], with a firm, tense [쯤].
You'll know it worked when you can swap the parts and still choose correctly. Replace 세 시 with 한 달 and the verb with 걸려요, and you get 한 달쯤 걸려요, "It takes about a month." Replace the figure with 열 명 and the verb with 왔어요, and you get 열 명쯤 왔어요 (yeol myeongjjeum wasseoyo) [열 명쯤 와써요], "About ten people came."
The same steps handle the question words in the table: 언제쯤 (about when) and 어디쯤 (about where). For example, 지금 어디쯤이에요? (jigeum eodijjeumieyo) means "About where are you now?", and it is a natural question to a friend who is on the way.
Once you can build the pattern, the next question is how 쯤 differs from the other words for "about".
How Is 쯤 Different from Similar Forms?
The 쯤 particle attaches to time points and amounts in speech and everyday writing, while 정도, 경 and 약 each have a narrower job. Four forms compete, and the table puts them side by side.
| Form | Type | Typical word | Example |
|---|---|---|---|
| 쯤 | suffix, attached | time points, amounts, question words, places | 세 시쯤 만나요. = We meet around three. |
| 정도 | separate word, after a space | amounts and degree | 세 시간 정도 걸려요. = It takes about three hours. |
| 경 | written suffix | dates and clock times, not lengths | 3월 초경, 5시경 = around early March, around five |
| 약 | written prefix, before a number | numbers and counts | 약 열 명 = about ten people |
The test is the kind of word and the register. For a time point in speech, 쯤 is the default. For an amount or a degree, 쯤 and 정도 are both common, and 정도 is slightly more neutral: 두 시간쯤 걸려요 and 두 시간 정도 걸려요 mean the same. For a written notice about a date, 경 is typical: 오후 세 시경 도착 예정입니다 means "Arrival is expected around three in the afternoon." For a figure in a news report, 약 is typical: 약 열 명 means "about ten people".
One difference is worth remembering: 정도 also carries the meaning of "degree" when it follows other words. 어느 정도 means "to some extent", and 이 정도면 충분해요 means "This much is enough." 쯤 can do the same job after a pointing word: 이쯤이면 충분해요 (ijjeumimyeon chungbunhaeyo) [이쯔미면 충분해요] means "About this much is enough."
The lesson on the 씩 each particle shows how to add "each" to a count, and the lesson on the (이)나 or particle covers 두 시간이나 ("as much as two hours"), which stresses that an amount is large rather than approximate. The comparison is clear, so the next section collects the limits of the rule.
When Do You Use 쯤, and When Not?
Use 쯤 whenever you give an estimate of a time, an amount, a place or a degree and want to sound relaxed about it. Beyond that core job, three points control where 쯤 sits in the sentence.
Where 에 Goes
Put 에 after 쯤, not before it: 세 시쯤에 만나요. The particle 에 marks the whole phrase "around three" as a point in time, so it closes the phrase. The version without 에 is also correct and very common in speech: 세 시쯤 만나요. The lesson on the time particle 에 covers when 에 is needed with ordinary time words.
Combining 쯤 with Other Particles
Yes. 쯤 can be followed by 은/는, 도 or 이/가 like a noun: 세 시쯤은 괜찮아요 (se sijjeumeun gwaenchanayo) means "Around three is fine." It can also be followed by 까지 for a rough end point: 다섯 시쯤까지 기다릴게요 means "I will wait until about five." The lesson on the 까지 until particle explains the end-point meaning.
When Does 쯤 Not Fit?
- Exact figures. Do not combine 쯤 with words such as 정확히 (exactly) or 딱 (right on): 정확히 세 시에 만나요 is correct, and 정확히 세 시쯤 is not.
- Verbs. Do not attach 쯤 to a verb stem. To say "be about to do", Korean uses a verb pattern such as -(으)려고 하다 instead.
- Formal written dates. Prefer 경 for "around" with a date in a notice, and 약 for numbers in a report. 쯤 is acceptable but sounds spoken.
- Words that are already vague. Do not add 쯤 to words such as 가끔 (sometimes) or 보통 (usually), because they already carry no exact figure.
One honest limit: the choice between 쯤 and 정도 for amounts is partly a matter of habit. Many native speakers use both without noticing a difference, and two speakers may disagree about which sounds better. The table gives safe defaults, but real speech mixes them. With the uses sorted, the next section lists the mistakes that come from mixing them up.
What Mistakes Do Learners Make?
Learners make four common mistakes with 쯤. Each one follows the pattern "learners often assume X; actually Y, because Z".
- Adding 쯤 to an exact figure. Learners often assume 쯤 is a polite softener, so they write 정확히 세 시쯤. Actually 쯤 means "roughly", so it contradicts "exactly". Use 쯤 only when you are estimating.
- Attaching 쯤 to a verb. Learners write 먹쯤 for "about to eat". Actually 쯤 attaches to nouns, numbers and question words, not to verb stems. Use a different pattern for "about to".
- Putting a space before 쯤. Learners write 세 시 쯤. Actually 쯤 is attached, while 정도 is the word that takes a space: 세 시쯤 but 세 시간 정도.
- Placing 에 before 쯤. Learners write 세 시에쯤 만나요 because 에 normally follows the time. Actually 쯤 closes the approximate phrase and 에 follows it: 세 시쯤에 만나요, or the version with no 에.
A practical rule of thumb: if you could replace the figure with "or so" in English, 쯤 fits; if "exactly" fits, it does not. The practice below checks both halves of that rule.

Fill the gap: 세 시__ 만나요. (Let us meet around three.)
Show answer
쯤
The time is approximate, so 쯤 attaches to it. 에서 marks a place, and 약 is a prefix that goes before a number.
Which sentence means "We meet at exactly three"?
Show answer
정확히 세 시에 만나요.
쯤 means "roughly", so it contradicts 정확히 (exactly). Drop 쯤 and use 에.
Which sentence is written correctly?
Show answer
세 시쯤 만나요.
쯤 attaches with no space, and 에 can only come after 쯤, never before it.
If you add 에 to the phrase 세 시쯤, where does it go?
Show answer
After 쯤: 세 시쯤에 만나요
쯤 closes the approximate phrase, and 에 follows it. Dropping 에 is also correct in speech.
What does 언제쯤 도착해요? mean?
Show answer
About when do you arrive?
쯤 attaches to question words: 언제쯤 means "about when". "About where" would be 어디쯤.
Which word for "about" is a written prefix placed before a number, as in a news report?
Show answer
약
약 goes before the number: 약 열 명. 쯤 and 경 attach after the word, and 정도 follows it after a space.
Which of these words for "about" is written as a separate word after a space?
Show answer
정도
정도 takes a space (세 시간 정도), while 쯤 and 경 attach directly (세 시쯤, 5시경).
What does 한 달쯤 걸려요 mean?
Show answer
It takes about a month.
쯤 marks the figure before it as an estimate, so 한 달쯤 is "about a month".
Exercise 1: Choose the form. Fill in the blank with 쯤 or 에서: 세 시__ 만나요. (Let us meet around three.)
Exercise 2: Fix the error. A learner writes 정확히 세 시쯤 만나요 for "We meet at exactly three". Correct it.
Exercise 3: Translate. "It takes about two hours." (two hours = 두 시간, it takes = 걸려요)
Exercise 4: Write your own. Write a question that asks a friend about what time they will arrive (arrive = 도착해요, what time = 몇 시).
Answer Key
- Exercise 1: 세 시쯤 만나요. The meeting time is approximate, so 쯤 fits. 에서 marks a place and does not fit a time.
- Exercise 2: 정확히 세 시에 만나요. (jeonghwakhi se sie mannayo) "Exactly" needs an exact figure, so drop 쯤 and use 에.
- Exercise 3: 두 시간쯤 걸려요. (du siganjjeum geollyeoyo) [두 시간쯤 걸려요] Another correct answer is 두 시간 정도 걸려요.
- Exercise 4: One model answer: 몇 시쯤 도착해요? (myeot sijjeum dochakaeyo) [멷씨쯤 도차캐요] = "About what time do you arrive?" The question word 몇 시 takes 쯤 like any time expression.
If you missed Exercise 1 or 2, reread the comparison table and the list of cases where 쯤 does not fit. The next section shows where to go from here.
Next Lessons and Where to Go from Here
The next lesson in this set is 만 vs 밖에, which compares two ways to say "only". The lesson before it in the set is the 밖에 only particle. To review time words, return to the time particle 에 and the 까지 until particle.
What this lesson does not cover. This lesson does not cover the verb patterns for guessing, such as -(으)ㄹ 것 같다, the related form 즈음, or number lists with 두세 and 서너. Every lesson in this particle set is listed on korean comparison particles.
In short, the 쯤 about particle makes a time, an amount, a place or a degree approximate: attach it with no space, never use it with an exact figure, and put 에 after it when you need one.
Frequently Asked Questions
What does 쯤 mean? 쯤 means "about", "around" or "roughly". It follows a time, an amount or a place word and tells the listener that the figure is approximate. 세 시쯤 만나요 means "Let us meet around three", and 이쯤에서 그만해요 means "Let us stop around here." The speaker gives an estimate, not an exact figure.
How do I form 쯤? Attach 쯤 straight to a time or amount expression with no space and no change: 세 시쯤, 한 달쯤, 열 명쯤, 언제쯤. It has one form, so the last sound of the noun does not matter. The ㅉ is a tense sound, so say it with a tight throat and no puff of air: [쯤]. It never follows a verb stem.
What is the most common mistake with 쯤? Learners attach 쯤 to an exact figure, or add it to a verb. A speaker who says 정확히 세 시쯤 (exactly around three) contradicts themselves, because 정확히 means exactly and 쯤 means roughly. Use 쯤 only when you are estimating, and attach it only to times, amounts, places and question words.
How is 쯤 different from similar forms? 쯤 attaches to the word and suits time points and amounts. 정도 is a separate word that suits amounts and degree (세 시간 정도). 경 is a written suffix for dates and clock times (5시경). 약 is a written prefix placed before a number (약 열 명). In speech, 쯤 and 정도 are the common pair.
Do I use 쯤 in speech, writing or both? Both, but it leans toward speech and everyday writing. It appears in chat, polite conversation and informal essays. Formal notices and news reports often prefer 경 for dates and 약 for numbers. The particle does not change with politeness, so 세 시쯤 works in casual and polite sentences.
