Mastering Korean Native Numbers: The Definitive Guide to Sino-Korean and Native Korean Systems

Korean native numbers can be confusing for learners due to the existence of two distinct systems: Sino-Korean and Native Korean. This guide will help you understand when to use each system, providing practical examples and clear explanations to enhance your fluency.

Understanding the Two Pillars: Sino-Korean vs. Native Korean

Korean uses two primary number systems: Sino-Korean and Native Korean. Sino-Korean numbers are derived from Chinese and are used in formal, official, and mathematical contexts. Native Korean numbers, on the other hand, are used in everyday conversations and for counting people and objects.

Key Differences

Sino-Korean	Native Korean
일 (il)	하나 (hana)
이 (i)	둘 (dul)
삼 (sam)	셋 (set)
사 (sa)	네 (ne)
오 (o)	다섯 (daseot)
육 (yuk)	여섯 (yeoseot)
칠 (chil)	일곱 (ilgop)
팔 (pal)	여덟 (yeodeol)
구 (gu)	아홉 (ahop)
십 (sip)	열 (yeol)

When to Use Sino-Korean Numbers (The Official & Financial Language)

Sino-Korean numbers are used in formal contexts, such as dates, money, phone numbers, addresses, measurements, and large numbers. Here are some specific contexts and examples:

Dates and Times

• Today is 일월 이일 (il-wol i-il), which means January 2nd.
• The meeting is at 오시 삼십분 (o-si sam-sip-bun), or 5:30 PM.

Money

• This item costs 이만 원 (i-man won), which is 20,000 won.
• I need 삼백 원 (sam-baek won), or 300 won.

Phone Numbers and Addresses

• My phone number is 오일삼사오사오 (o-il-sam-sa-o-sa-o), or 013-456-7890.
• My address is 일사오사오 (il-sa-o-sa-o), or 145-678.

When to Use Native Korean Numbers (For Daily Counting and People)

Native Korean numbers are used for counting people, age, and general objects in everyday conversations. Here are some practical examples:

Counting People and Objects

• There are 세 명 (se myeong) of us going to the park.
• I have 두 개의 (du gae) apples.

Age

• She is 스무 살 (seumu sal), or 20 years old.
• He is 서른 살 (seoreun sal), or 30 years old.

Mastering Large Numbers: The Role of '만' (Man)

When dealing with large numbers in Korean, the unit '만' (man) is crucial. '만' represents 10,000. Here’s how to use it:

Examples

• 이만 원 (i-man won) means 20,000 won.
• 삼만 원 (sam-man won) means 30,000 won.
• 오십만 원 (o-sip-man won) means 500,000 won.

Handling Large Numbers

To express numbers larger than 10,000, you use '만' followed by the remaining digits. For example:

• 이백만 원 (i-baek-man won) means 2,000,000 won.
• 삼천만 원 (sam-cheon-man won) means 30,000,000 won.

Practical Application Scenarios

Counting Money

When paying for items, you will use Sino-Korean numbers. For example:

• 이만 원 (i-man won) for 20,000 won.
• 오백 원 (o-baek won) for 500 won.

Telling Time

For telling time, you use Sino-Korean numbers. For example:

• 오시 삼십분 (o-si sam-sip-bun) for 5:30 PM.
• 일시 오십분 (il-si o-sip-bun) for 1:50 AM.

Common Mistakes and How to Avoid Them

Switching Between Systems

A common mistake is switching between Sino-Korean and Native Korean numbers inappropriately. To avoid this:

1. Identify the Context: Determine if the situation requires formal or informal counting.
2. Practice with Examples: Use the examples provided to practice switching between the two systems.
3. Listen and Repeat: Listen to native speakers and repeat after them to get the pronunciation right.
