K‑drama cliff‑hangers, K‑pop chart numbers, and that inevitable question “몇 살이에요?” (How old are you?). Sooner or later, you’re going to have to understand Korean numbers. Therefore, mastering Korean numbers is one of the smartest early wins for any learner. In this guide, you’ll discover exactly how the two Korean number systems work, when to use which, and how to avoid the classic rookie mistakes. By the end, you’ll be reading prices, telling time, and ordering 세 잔의 커피 (three coffees) with a confident smile.

 <h2>Korean Numbers: Understanding the Two Number Systems</h2>

 Before we dive into pronunciation drills, let’s address the elephant in the room: yes, Korean uses two parallel sets of numbers. One set, called Native Korean, grew organically on the peninsula. The other, Sino‑Korean, arrived centuries ago with Chinese characters and is still used for anything countable above 100, money, phone numbers, dates, and mathematics.

 Most beginners panic at the thought of doubling their study load, but take heart: each system has clear jobs. Memorise the contexts and you’ll know instinctively which digits to reach for.

 <h3>Native Korean Number System</h3>

 Native Korean numbers feel friendly and down‑to‑earth. You’ll hear them whenever the conversation is personal, tactile, or close‑range; things you can point at or put a hand around.

 Common Uses
 <ul>
 <li>ages (especially under 30): 스물세 살 (23 years old)</li>
 <li>counting physical objects: 사과 다섯 개 (five apples)</li>
 <li>telling the hour on a 12‑hour clock: 네 시 (4 o’clock)</li>
 <li>informal counting in games: 하나, 둘, 셋… ― “Ready, set, go!”</li>
 </ul>

 Numbers 1 ‑ 20
 <ul>
 <li>1 하나 (ha‑na)</li>
 <li>2 둘 (dul)</li>
 <li>3 셋 (set)</li>
 <li>4 넷 (net)</li>
 <li>5 다섯 (da‑seot)</li>
 <li>6 여섯 (yeo‑seot)</li>
 <li>7 일곱 (il‑gop)</li>
 <li>8 여덟 (yeo‑deol)</li>
 <li>9 아홉 (a‑hop)</li>
 <li>10 열 (yeol)</li>
 <li>11 열하나 (yeol‑ha‑na)</li>
 <li>12 열둘 (yeol‑dul)</li>
 <li>13 열셋 (yeol‑set)</li>
 <li>14 열넷 (yeol‑net)</li>
 <li>15 열다섯 (yeol‑da‑seot)</li>
 <li>16 열여섯 (yeol‑yeo‑seot)</li>
 <li>17 열일곱 (yeol‑il‑gop)</li>
 <li>18 열여덟 (yeol‑yeo‑deol)</li>
 <li>19 열아홉 (yeol‑a‑hop)</li>
 <li>20 스물 (seu‑mul)</li>
 </ul>

Shortcut alert: 하나 → 한 and 둘 → 두 when they stand in front of counters: 한 명, 두 잔.

 <h3>Sino‑Korean Number System</h3>

 If Native Korean is the cosy cottage, Sino‑Korean is the high‑rise office block, built for scale. It handles all the big‑picture math that Native numbers can’t.

 Common Uses
 <ul>
 <li>money: 오천 원 (₩5,000)</li>
 <li>minutes&nbsp;&amp;&nbsp;seconds: 삼십오 분 (35 minutes)</li>
 <li>dates&nbsp;&amp;&nbsp;years: 이천이십오 년 (2025)</li>
 <li>phone numbers&nbsp;&amp;&nbsp;codes: 공일‑구칠팔…</li>
 <li>any number ≥ 100: 백팔십구 (189)</li>
 </ul>

 Numbers 0‑20
 <ul>
 <li>0 영 / 공 (yeong / gong)</li>
 <li>1 일 (il)</li>
 <li>2 이 (i)</li>
 <li>3 삼 (sam)</li>
 <li>4 사 (sa)</li>
 <li>5 오 (o)</li>
 <li>6 육 (yuk)</li>
 <li>7 칠 (chil)</li>
 <li>8 팔 (pal)</li>
 <li>9 구 (gu)</li>
 <li>10 십 (sip)</li>
 <li>11 십일 (sip‑il)</li>
 <li>12 십이 (sip‑i)</li>
 <li>13 십삼 (sip‑sam)</li>
 <li>14 십사 (sip‑sa)</li>
 <li>15 십오 (sip‑o)</li>
 <li>16 십육 (sip‑yuk)</li>
 <li>17 십칠 (sip‑chil)</li>
 <li>18 십팔 (sip‑pal)</li>
 <li>19 십구 (sip‑gu)</li>
 <li>20 이십 (i‑sip)</li>
 </ul>

영 vs 공: use 공 for phone numbers and locker codes; 영 for scores, temperatures, and maths.

 <h2>How to Form Larger Korean Numerals</h2>

 Bigger numbers in Korean stack together like Lego bricks: once you know the base pieces, you can click them into anything from eleven to a billion. Each number family follows its own blueprint, so let’s zoom in on how to build with both.

 <h3>Forming Larger Numbers with Native Korean</h3>

 Native Korean tops out at 99 and shines in conversation; hours, ages, and counters all lean on it. Because this system never developed a standalone word for zero, native speakers simply skip 0 and rely on unique tens roots for round numbers. When a number ends in 0, you just say the tens root by itself; no extra word needed (e.g., 예순 = 60). Combine that root with a unit for everything else: 예순여덟 (68), 마흔둘 (42).

 Building rules
 <ul>
 <li>Unique tens roots:
 <ul>
 <li>20 스물 (seu‑mul)</li>
 <li>30 서른 (seo‑reun)</li>
 <li>40 마흔 (ma‑heun)</li>
 <li>50 쉰 (swin)</li>
 <li>60 예순 (ye‑sun)</li>
 <li>70 일흔 (il‑heun)</li>
 <li>80 여든 (yeo‑deun)</li>
 <li>90 아흔 (a‑heun)</li>
 </ul>
 </li>
 <li>Combine tens + single unit by simply adding the single unit: 스물다섯 (25), 마흔일곱 (47)</li>
 <li>For hours, add 시: 여섯 시 (6 o’clock)</li>
 <li>For age, add 살: 서른두 살 (32 years old)</li>
 </ul>

 Native numbers rarely wander above the everyday, but nailing them keeps your speech natural and prevents the rookie error of mixing systems.

 <h3>Forming Larger Numbers with Sino‑Korean</h3>

 Sino‑Korean is the workhorse for prices, dates, phone numbers, and anything mathematical. Its logic is straightforward: build numbers from left to right by stacking place‑value words (십, 백, 천, 만…) after the relevant digit.

 <h4>Building Bigger Korean Numbers</h4>

 <ul>
 <li>11 – 19 (십 + unit) 
 Place the unit (1‑9) directly after 십 (10). 
 Examples
 <ul>
 <li>12 십이 (sip-i)</li>
 <li>15 십오 (sip-o)</li>
 <li>18 십팔 (sip-pal)</li>
 </ul>
 </li>
 <li>20, 30 … 90 (leading digit + 십) 
 Combine the leading digit (2‑9) + 십. 
 Examples
 <ul>
 <li>20 이십 (i-sip)</li>
 <li>30 삼십 (sam-sip)</li>
 <li>60 육십 (yuk-sip)</li>
 <li>80 팔십 (pal-sip)</li>
 </ul>
 </li>
 <li>21 – 99 (tens + unit) 
 Add the following together: (leading digit + 십) + unit digit. 
 Examples
 <ul>
 <li>26 이십육 (i-sip-yuk)</li>
 <li>34 삼십사 (sam-sip-sa)</li>
 <li>56 오십육 (o-sip-yuk)</li>
 <li>78 칠십팔 (chil-sip-pal)</li>
 <li>99 구십구 (gu-sip-gu)</li>
 </ul>
 </li>
 <li>Hundreds (digit + 백) 
 백 (100) can stand alone. Add a digit in front for multiples of 100. 
 Examples
 <ul>
 <li>100 백 (baek)</li>
 <li>200 이백 (i-baek)</li>
 <li>514 오백십사 (o-baek-sip-sa)</li>
 <li>999 구백구십구 (gu-baek-gu-sip-gu)</li>
 </ul>
 </li>
 <li>Thousands (digit + 천) 
 천 (1,000) stands alone for 1,000. Combine with hundreds and below for other values. 
 Examples
 <ul>
 <li>1,000 천 (cheon)</li>
 <li>1,234 천이백삼십사 (cheon-i-baek-sam-sip-sa)</li>
 <li>5,700 오천칠백 (o-cheon-chil-baek)</li>
 </ul>
 </li>
 <li>Ten‑thousands and beyond (digit + 만, 억) 
 만 = 10,000. Treat everything left of 만 as one four‑digit block, then repeat for 억 (100 000 000) if needed. 
 Examples
 <ul>
 <li>35,000 삼만오천 (sam-man-o-cheon)</li>
 <li>100,000 십만 (sip-man)</li>
 <li>1,000,000 백만 (baek-man)</li>
 <li>2,304,500 이백삼십만사천오백 (i-baek-sam-sip-man-sa-cheon-o-baek)</li>
 </ul>
 </li>
 </ul>

Tip: Read large numbers from left to right, grouping by 만 (10 000). This keeps Korean place values intuitive once you get the hang of four‑digit blocks.
 
 Because prices in Korea often sit in the 만 (10,000) range, you’ll hear 삼만오천 원 (₩ 35,000) or even 백만 (1,000,000) daily. Practice by reading shopping sites aloud; it’s addictive listening prep!

 <h2>Understanding Time in Korean</h2>

 Telling the time is where Korea’s dual‑number system really flexes its muscles. Native Korean takes care of hours (because hours feel like ‘countable things’), while Sino‑Korean handles the precise minutes and seconds, the realm of math and schedules.

 두 시 삼십 분 (02:30) 열한 시 십오 분 (11:15)

 <h3>Core pattern</h3>
 <ul>
 <li>Hour (Native) + 시</li>
 <li>Minute (Sino) + 분</li>
 <li>Second (Sino) + 초 (optional)</li>
 </ul>

 <h3>Handy add‑ons</h3>
 <ul>
 <li>정각 (jeong‑gak): “on the dot”.
 <ul>
 <li>열두 시 정각 → 12:00 exactly</li>
 </ul>
 </li>
 <li>반 (ban): “half past”.
 <ul>
 <li>여섯 시 반 → 6:30</li>
 </ul>
 </li>
 <li>오전 / 오후 (ojeon / ohu): AM / PM markers that come before the hour.
 <ul>
 <li>오후 세 시 → 3:00 PM</li>
 <li>오전 열 시 반 → 10:30 AM</li>
 </ul>
 </li>
 </ul>

 <h3>24‑hour clock</h3>
 Transport timetables, the military, and news broadcasts often use the 24‑hour format written (or spoken) with pure Sino‑Korean numerals:
 <ul>
 <li>18:45 → 십팔시 사십오분</li>
 <li>00:05 → 영시 오분</li>
 </ul>

 <h3>Spoken shortcuts</h3>
 Native speakers frequently drop 분 and 초 when the context is clear:
 <ul>
 <li>다섯 시 십오(분) → 5:15</li>
 <li>두 시(정각) → 2:00 on the dot</li>
 </ul>

 <h3>Mini practice list</h3>
<ul>
 <li>1:05 – 한 시 오 분 (han si o bun)</li>
 <li>3:30 – 세 시 반 (se si ban)</li>
 <li>7:45 – 일곱 시 사십오 분 (ilgop si sa‑sip‑o bun)</li>
 <li>12:00 – 열두 시 정각 (yeol‑du si jeong‑gak)</li>
</ul>
Need to set up a study date? Try: 여섯 시 반에 만나요! – Let’s meet at 6:30.

<h2>Pro Tips &amp; Common Pitfalls</h2>
<ol>
 <li>Mixing systems: Resist saying 오십 살 for a 12‑year‑old; stick to Native ages under 30.</li>
 <li>Dropping counters: In Korean, you never say a bare number + noun. Add 개, 명, 권 etc.</li>
 <li>Forgetting spaces: When writing, leave a gap between the written word and the counter: 다섯 개. Numerals can stick: 5개.</li>
 <li>Saying zero: Temperature? Use 영 도. Phone number? 공.</li>
 <li>Pronunciation shortcuts: 하나 → 한 before counters (한 잔), 둘 → 두 (두 시).</li>
</ol>

How to Use Korean Numbers

korean numbers1

Korean uses Native Korean numbers for counting people, objects, hours, and ages up to about 30, while Sino‑Korean numbers cover money, dates, phone numbers, minutes, seconds, math, and any figure from 100 upward.

What are the two number systems in Korean and when should I use each?

Combine place‑value words left to right: 십 (10) + unit for 11‑19; leading digit + 십 for 20‑90; add a unit digit for 21‑99; use 백 (100), 천 (1,000), 만 (10,000), 십만 (100,000) and 백만 (1,000,000) in the same way—e.g., 26 = 이십육, 1,234 = 천이백삼십사, 35,000 = 삼만오천.

How do I form larger numbers with Sino‑Korean numerals?

Native Korean tops out at 99 and never developed a standalone word for zero; round tens are unique roots like 스물 (20) and 예순 (60). When a number ends in 0, you simply say the tens root—예순 equals 60—with no extra word for zero.

Why is there no zero in Native Korean numbers?

Language is a gateway to culture, and swear words are one of the most peculiar ways people express strong emotion, humor, or frustration. The Korean language is no exception—Korean swear words can reveal a lot about cultural values, social hierarchies, and even comedic styles. However, because Korean culture places a high emphasis on respect and politeness, dropping a curse word at the wrong time can lead to a serious social faux pas. That said, let’s dive into some of the most common Korean swear words, their pronunciation, and the context behind them.

 <h2>A Quick Overview of Korean Language Etiquette</h2>
 
 Before we jump into specific words, it’s important to understand why etiquette matters so much in Korea. In many Western cultures, swear words might be tossed around playfully among friends or even co-workers. In Korea, social hierarchies are far more pronounced. Age, status, and the setting of a conversation dictate how you should speak, from your level of formality to the specific phrases you use.
 
 
 Remember, there are multiple speech levels in Korean—honorifics are used for people older than you or those who hold higher status. Swearing while using polite language is almost always jarring. It’s basically the linguistic equivalent of wearing a tuxedo to a beach party. Not a good mix.

 <h2>18 Korean Swear Words and When to Use Them</h2>
 
 Let’s get into the core of the topic: the Korean swear words themselves. We’ll list each word, a rough pronunciation guide, what it literally means, when it’s used, and why you might want to avoid using it. Get ready—some of these can be quite strong. While you’re at it, you might also want to explore more creative forms of put-downs with lighter impact, like certain

 <h2>When Swearing in Korean Might Be (Somewhat) Acceptable</h2>
 
 Swear words aren’t always used maliciously. In some cultures, a mild curse word can even serve as a term of endearment among very close friends. The same might be true in certain Korean social circles, but the context is crucial. If you find yourself looking for more casual expressions, consider discovering popular 
 <a href="https://tandem.net/blog/korean-slang">Korean slang</a> that’s still more polite than outright cursing.
 
 <ul>
 <li>Close Friend Groups: Some young adults might casually throw around words like 씨발 in a joking manner. But if you’re an outsider, using these words could be seen as you overstepping boundaries.</li>
 <li>Emotional Moments in Dramas or Movies: You’ll hear swear words in K-dramas, especially during intense scenes. This is a good opportunity to understand how and why these words are used, but it doesn’t mean you should mimic them in real life.</li>
 <li>Comedic Routines: Sometimes comedians use swear words for shock value or comedic effect, just as they do in other countries.</li>
 </ul>

 <h3>Always Watch and Listen First</h3>
 
 Because Korean culture is built on nuanced social hierarchies, you’ll want to observe how native Koreans use (or don’t use) these words in various settings. Swearing might be acceptable among close-knit friends who grew up together, but it might be offensive if it comes from someone outside that inner circle. Basically, read the room.
 

 
 To deepen your understanding of conversational Korean, you might also want to look beyond swear words. For instance, exploring 
 <a href="https://tandem.net/blog/korean-idioms">Korean idioms</a> can give you insight into how native speakers express ideas more poetically, while tapping into the cultural nuances behind everyday speech.
 

 <h2>How to Avoid Offense (and What to Say Instead)</h2>
 
 Even if you know these words, you may not want to use them. But what if you’re angry or frustrated and really want to express it? Here are some more polite ways to show annoyance or anger without resorting to heavy swearing:
 
 <ul>
 <li>아이씨 (Ai-ssi): A mild exclamation that can mean something like “Oh, come on!”</li>
 <li>아이고 (Aigo): An exclamation that conveys frustration or exasperation but is not offensive.</li>
 <li>진짜 (Jinjja) / 정말 (Jeongmal): Both mean “really” or “seriously,” often used to express disbelief or mild annoyance.</li>
 </ul>

 <h2>Wrapping Up with Caution</h2>
 
 Korean swear words can be intriguing, especially if you’re a language nerd who loves diving into every nook and cranny of a culture’s vocabulary. These words do more than express anger; they reflect cultural norms, social hierarchies, and sometimes a playful sense of humor among friends.
 
 
 However, don’t assume that just because you understand the literal meaning of these words, you can whip them out whenever you like. Take into account age, setting, and the relationship you have with the person you’re talking to. A swear word among friends might be a term of endearment—or it might end a friendship if misused.
 

 Here’s a quick recap:
 <ol>
 <li>Context is King: Knowing when (and if) to use these words is more important than just memorizing them.</li>
 <li>Start Polite: Korean culture has a strong emphasis on formality and respect. Play it safe and stay polite.</li>
 <li>Observe and Learn: Watch K-dramas, variety shows, and real-life interactions to see how Koreans use (or avoid) these words.</li>
 <li>Choose Softer Alternatives: If you’re upset, there are mild expressions that convey annoyance without outright offending someone.</li>
 <li>Practice with Native Speakers: The best way to learn the nuances is to engage with people who speak Korean, but always remain respectful.</li>
 </ol>

 
 Finally, remember that language is a living, breathing entity. Meanings evolve, new slang emerges, and cultural norms shift. Stay curious and open-minded. By doing so, you won’t just learn words—you’ll gain a deeper insight into the Korean way of life. Good luck, study hard, and remember: with great swear words comes great responsibility!
