Understanding the Two Number Systems in Korean
Sino-Korean Numbers
Sino-Korean numbers originate from Chinese and are used for a wide variety of purposes in modern Korean. They are based on Chinese characters and are commonly used in formal, official, and mathematical contexts. Sino-Korean numbers are: 1 (일, il), 2 (이, i), 3 (삼, sam), 4 (사, sa), 5 (오, o), 6 (육, yuk), 7 (칠, chil), 8 (팔, pal), 9 (구, gu), 10 (십, sip), and so on.
Native Korean Numbers
Native Korean numbers are unique to the Korean language and are generally used for counting objects, people, and age in informal situations. These numbers are: 1 (하나, hana), 2 (둘, dul), 3 (셋, set), 4 (넷, net), 5 (다섯, daseot), 6 (여섯, yeoseot), 7 (일곱, ilgop), 8 (여덟, yeodeol), 9 (아홉, ahop), 10 (열, yeol).
When to Use Sino-Korean Numbers
1. Telling Time (Minutes and Seconds)
Use Sino-Korean numbers for minutes and seconds. For example, 10 minutes is 십 분 (sip bun), and 30 seconds is 삼십 초 (samsip cho).
2. Dates, Months, and Years
Sino-Korean numbers are used for calendar dates, months, and years. For example, 2024년 (i-cheon-i-sip-sa nyeon) for the year 2024, 6월 (yuk-wol) for June, and 15일 (sip-o il) for the 15th day.
3. Phone Numbers, Addresses, and Prices
All numbers used in phone numbers, addresses, and prices are Sino-Korean. For example, 전화번호 010-1234-5678 (jeonhwabeonho 010-1234-5678) and 5,000원 (o-cheon won) for 5,000 Korean Won.
4. Counting Large Numbers and Mathematics
Anything involving large numbers, mathematical operations, or statistics uses the Sino-Korean system. For example, 100 (백, baek), 1,000 (천, cheon), 10,000 (만, man).
When to Use Native Korean Numbers
1. Counting Objects (with Counters)
Use Native Korean numbers when counting objects, animals, or people, especially up to 99, and always with a counter word. For example, three apples: 사과 세 개 (sagwa se gae); five people: 다섯 명 (daseot myeong).
2. Telling Age (Informal and with 살)
When talking about age informally or with the word 살 (sal), use Native Korean numbers. For example, 20 years old: 스무 살 (seumu sal). For official or legal purposes (such as forms), Sino-Korean numbers can also be used with 세 (se).
3. Hours (in Telling Time)
Hours on the clock are given using Native Korean numbers, while minutes are Sino-Korean. For example, 3:10 is 세 시 십 분 (se si sip bun).
4. Counting Items Up to 99
Native Korean numbers are generally used for counting items up to 99. Beyond that, Sino-Korean numbers are preferred.
Common Mistakes and How to Avoid Them
Mixing Number Systems Incorrectly
A frequent error among Korean learners is mixing the two number systems in one phrase. For example, saying “십하나 개” instead of “열한 개” for 11 items. Remember: stick to one system per context.
Forgetting Counters
Both number systems require the use of counters when counting things, people, or animals. Don’t forget to add the appropriate counter after the number.
Using Native Numbers for Dates and Money
Dates, money, and phone numbers always use Sino-Korean numbers—never the native system.
Practical Tips for Mastering Korean Numbers
- Practice with real-life examples: Try telling the time, counting objects, and stating your age using both systems.
- Use flashcards to memorize both sets of numbers and their common counters.
- Engage with interactive exercises and quizzes, such as those available on Talkpal, to reinforce your understanding.
- Listen to native speakers and note which system they use in different scenarios.
- Don’t be afraid to make mistakes—practice is key to fluency.
