Korean Counter Jan (잔): Count Cups and Glasses of Drink

What you'll learn

• Count one to ten cups or glasses of drink with 잔, using the correct native number forms.
• Order drinks in a cafe and ask 몇 잔 to find out how many.
• Tell 컵 (the cup as an object) from 잔 (the counter for the drink).
• Understand why 한잔 can mean "a drink" in a social invitation.

Prerequisites: native Korean numbers 1-10. Estimated time: 30 minutes.

Korean Counter Jan: the Essentials

The Korean counter jan (잔) is a short word that follows a number and means "a cup or glass of". A counter is a word that tells you what kind of unit a number refers to. English does the same when it says "two cups of tea" or "three glasses of water". Korean needs the counter almost every time, and 잔 is the one for drinks poured into a cup, glass or small drinking vessel.

The pattern is: drink + native number + 잔.

The word 잔 is also a noun. It means a small drinking cup or glass on its own, and it appears inside other words: 찻잔 (a teacup) and 술잔 (a liquor glass). The counter grew out of this noun. When you say 물 두 잔, you are saying "two glasses' worth of water".

Like 병 and 그릇 (but not 인분, which takes Sino-Korean numbers), 잔 takes native Korean numbers (하나, 둘, 셋), not Sino-Korean ones (일, 이, 삼). So 두 잔 is correct and 이 잔 is not. You can see the whole system in how Korean counters work. The next section shows the word order in full sentences.

How Do You Use 잔 in a Sentence?

To use 잔 in a sentence, put the drink first, then the native number, then 잔: 커피 두 잔을 마셨어요 (I drank two cups of coffee). English puts the number before the noun, but Korean puts the counter phrase after the noun, and the counter is an extra word that English does not need.

Three patterns cover almost every real sentence.

Here are more sentences to hear and repeat.

• 하루에 물을 여덟 잔 마셔요. (I drink eight glasses of water a day.)
• 오늘 커피를 한 잔도 안 마셨어요. (I have not had even one cup of coffee today.)
• 손님이 다섯 분이라서 차 다섯 잔 준비했어요. (Five guests are coming, so I prepared five cups of tea.)

Notice that the particle 을/를 or 이/가 can sit on the drink (커피를 세 잔) or be dropped in speech (커피 세 잔 마셨어요). You never put a particle between the number and 잔. Writing 세를 잔 is always wrong. The particle 도 in 한 잔도 attaches to the whole counter phrase and means "even one".

Now you can build a full sentence. Next comes the number rule that makes the counter work.

Which Number System Does 잔 Take?

The counter 잔 takes native Korean numbers from 1 to 99. Five native numbers shorten before any counter, and learning those five forms once covers every counter that takes native numbers, including 병, 그릇 and 개.

Look at the "Spoken" column for 5, 6, 7 and 9. A final ㅅ or ㅂ is said as a plain stop ([ㄷ] or [ㅂ]), and that stop usually makes the ㅈ of 잔 tense, so you hear [ㅉ]. This is tensification, covered by the National Institute of Korean Language (국립국어원) standard pronunciation rules (표준 발음법). After ㄹ, as in 여덟 잔 and 열 잔, the standard form stays plain. The same effect gives 몇 잔 the sound [멷짠]. You do not have to think about it, because the mouth does it on its own.

Which Forms Shorten before 잔?

Five numbers shorten before 잔: 하나 becomes 한, 둘 becomes 두, 셋 becomes 세, 넷 becomes 네 and 스물 becomes 스무. These short forms are numeral determiners (수 관형사). They stand in front of the counter the way an adjective stands in front of a noun.

The shortening applies at the end of larger numbers too: 열한 잔 (11), 열두 잔 (12), 스물한 잔 (21). Round tens keep their full form: 서른 잔 (30), 마흔 잔 (40).

Expert tip: if you remember only one short form, remember 두. Learners often say 둘 잔, because 둘 is the number two they learned first. Korean ears hear this as a mistake. Use 두 잔 every time a counter follows.

What about Quantities above 99?

Native numbers stop at 아흔아홉 (99) in everyday counting, so a very large drink order switches to Sino-Korean numbers: 백 잔 (100 cups). Real orders this large are rare. A catering company or a festival stall might say 이백 잔 팔았어요 (we sold 200 cups). Everyday life stays between 한 잔 and 스무 잔.

When you write with digits, attach the counter without a space: 3잔, 12잔. This is how you see it on cafe menus and loyalty cards. When you write the number in Hangul, keep a space: 세 잔, not 세잔. The spacing rule comes from the 한글 맞춤법 (Hangul spelling rules), Article 43.

You can now count any round of drinks. Next is the question that asks for the count.

How Do You Ask How Many with 몇 잔?

To ask how many cups there are, say 몇 잔이에요? The word 몇 means "how many", so 몇 잔 means "how many cups or glasses". It is pronounced [멷짠] because the final ㅊ of 몇 is said as [ㄷ], which tenses the ㅈ.

The answer repeats the same pattern: number + 잔 + 이에요 or a verb. After 잔 the copula takes the 이에요 form because 잔 ends in a consonant, so you say 세 잔이에요. The ending 쯤 in 여섯 잔쯤 means "about", and it attaches directly to the counter phrase.

Cafe Dialogue

The dialogue below uses 잔 the way a real cafe does. The customer names each drink and its count, and the clerk confirms the total with 잔.

• 직원: 어서 오세요. 주문하시겠어요? (Welcome. Are you ready to order?)
• 손님: 아이스 아메리카노 두 잔 주세요. (Two iced americanos, please.)
• 직원: 따뜻한 음료도 필요하세요? (Do you need a hot drink too?)
• 손님: 네, 따뜻한 라테 한 잔 주세요. (Yes, one hot latte, please.)
• 직원: 모두 세 잔이에요. 여기서 드시고 가세요? (That is three drinks in all. Will you drink here?)
• 손님: 아니요, 포장해 주세요. (No, take-away, please.)

Notice that 아이스 (iced) and 따뜻한 (hot, literally "warm") describe the drink and come before it. They never replace the counter. Size words such as 큰 (big) behave the same way: 큰 라테 한 잔 means one big latte. For more lines like these, see Korean restaurant phrases. First, one pair of words needs sorting out.

컵 or 잔: What Is the Difference?

The word 컵 is the cup as an object, and 잔 is the counter for the drink inside it. 컵 is a loanword from English "cup", and you count the objects themselves with 개: 컵 두 개 (two cups). You count the drink with 잔: 물 두 잔 (two glasses of water). The two answers can describe the same table.

The third row shows a real overlap. In cooking, 컵 works as a measuring unit, so 물 한 컵 means one measuring cup of water. A Korean listener will also understand 물 한 컵 주세요 in a cafe, but it sounds like a measuring request. When a server hands you a drink, the natural count is 잔.

The distinction helps with a common trap. If a friend asks 컵 몇 개 필요해요? they want to know how many cup objects to bring. If they ask 몇 잔 마실 거예요? they want to know how much you plan to drink.

What Does 한잔 Mean as an Invitation?

한잔 written as one word is a noun meaning "a drink", and 한잔하다 means "to have a drink". The Korean dictionary of the National Institute of Korean Language (국립국어원 표준국어대사전) lists 한잔 as its own word, separate from 한 잔 (one cup) written with a space, and it also lists the verb 한잔하다, written as one word. When another word comes between, as in 한잔 더 하시겠어요?, the parts are spaced.

The invitation is very common in everyday talk.

On its own, 한잔하다 usually suggests alcohol, and context decides. 커피 한잔할래요? names the drink, so it is clearly about coffee. The invitation does not promise exactly one glass. People who say "let's have a drink" may stay for hours. The attached spelling marks the social meaning, and the spaced 한 잔 is the exact count.

Spelling here is flexible in real life. Many people write 한 잔 even for the invitation, and readers understand either way. The dictionary form is the attached one, so use 한잔 in careful writing. Next, compare 잔 with the other drink counters.

Which Counter Fits Which Drink?

잔 fits drinks served in a cup or glass, while 병 fits bottles and 캔 fits cans. The same drink can take all three counters, and the counter tells the listener how it arrives. Beer is the clearest case.

The 병 counter has its own lesson. For a soju table, people pour by the glass (소주 두 잔) but order by the bottle (소주 한 병 주세요). Counting the amount in the bottle uses 병, and counting each pour uses 잔.

Size and temperature words do not change the counter. 따뜻한 차 한 잔, 아이스 라테 두 잔 and 큰 주스 한 잔 all keep 잔. Words like 톨 (tall) or 그란데 (grande) on a chain menu are size labels for the drink, not counters. Learn the drink names in Korean drinks vocabulary.

Daily-Life Phrases with 잔

Most real uses of 잔 fall into a few daily scenes: ordering, hosting, health and nightlife. Learn these phrases as whole chunks, because the number and counter then come out together without thinking.

The particle 만 in 두 잔만 means "only", and it attaches to the counter phrase. The word 더 in 한 잔 더 means "one more", and it follows the counter. Drinking etiquette is its own topic, but one detail is useful: when you pour for an older person, people commonly use both hands, and the phrase 한 잔 받으세요 goes with that gesture.

Misconceptions about 잔

Learners often assume that 잔 is only for alcohol, or that 잔 and 컵 are the same word. Both ideas are wrong, and this section clears them up.

Misconception 1: 잔 is only for alcohol. 잔 counts any drink in a cup or glass. 물 한 잔, 우유 한 잔 and 커피 한 잔 are all normal. The link with alcohol comes from words like 술잔 and 한잔하다, not from the counter itself.

Misconception 2: 한 잔 and 한잔 are the same thing. The spaced form counts one glass. The attached form is a noun for a casual drink and the base of 한잔하다. In speech you cannot hear the space, so context decides.

Misconception 3: 컵 can replace 잔 in orders. 컵 is understood, but it names the vessel. For the drink you are served, use 잔.

Misconception 4: Sino numbers sound more formal. 잔 never takes them below 100. A formal setting changes the verb ending (드시겠어요?), not the number system.

Common Mistakes and Fixes

The most frequent errors with 잔 are about number forms and word order. Each one has a simple fix.

The second-to-last row points to the 그릇 counter, which counts bowls of rice, soup and noodles. Remember the rule of thumb: if you drink it from a cup or glass, use 잔. If you eat it from a bowl, use 그릇.

Practice Set

Try these five questions before you check the answers below.

1. Fill in the blank: 커피 ___ 잔 주세요. (three)
2. Say "two glasses of water" in Korean.
3. Which is the natural request in a cafe: 물 한 컵 주세요 or 물 한 잔 주세요?
4. What does 우리 한잔해요 invite you to do?
5. Correct this sentence: 맥주 이 잔 주세요.

Answers

1. 세. The sentence is 커피 세 잔 주세요.
2. 물 두 잔.
3. 물 한 잔 주세요. 컵 names the vessel, so it sounds like a measuring request.
4. To have a drink together, usually alcohol unless a drink such as coffee is named.
5. 맥주 두 잔 주세요. The counter 잔 needs a native number, so 이 becomes 두.

What This Lesson Does Not Cover

This lesson covers 잔 for drinks. It does not cover bottles (see the 병 counter), bowls and plates of food (see the 그릇 counter), or servings in a restaurant (see the 인분 counter). It also leaves out measuring units for liquids, such as 리터 (liter) and 밀리리터 (milliliter), which are borrowed from English and used on product labels.

What to Learn Next

The next lesson is the 병 counter, which counts bottles and often sits next to 잔 on the same menu. To see every drink and food counter side by side, go back to Counting Food and Drinks. Once the korean counter jan feels natural, practise it with Korean shopping phrases and the numbers in native Korean numbers 1-100.
