Definition: Saying “20” in Korean
In Korean, saying the number “20” isn’t as straightforward as it might seem. The Korean language employs two distinct number systems: the Sino-Korean system, derived from Chinese, and the Native Korean system, which is indigenous to the Korean peninsula. The choice of which system to use depends on the context of the situation. Therefore, there are two ways to say “20” in Korean: 이십 (isip) in the Sino-Korean system and 스물 (seumul) in the Native Korean system. Understanding the appropriate context for each is vital for effective communication.
Korean Number Systems
The Korean language utilizes two primary number systems: Sino-Korean and Native Korean. Each system has its own set of numbers and specific contexts in which it is used.
Mastering both systems is essential for fluency in Korean.
Sino-Korean Numbers
The Sino-Korean number system is derived from Chinese and is used for a variety of purposes, including telling time (minutes and seconds), counting money (especially larger amounts), measuring length, weight, and area, and stating phone numbers and dates (year, month, and day). Sino-Korean numbers are generally considered more formal than Native Korean numbers.
Native Korean Numbers
The Native Korean number system is indigenous to the Korean peninsula and is used for counting objects (up to 99), telling time (hours), stating age, and counting people. Native Korean numbers are generally considered more informal and are often used in everyday conversations.
Saying “20” in Korean
As mentioned earlier, the way to say “20” in Korean depends on which number system you are using. Let’s break down each system and its corresponding word for “20.”
“20” in Sino-Korean
In the Sino-Korean number system, “20” is expressed as 이십 (isip). This is a combination of two characters: 이 (i), which means “two,” and 십 (sip), which means “ten.” Therefore, 이십 (isip) literally translates to “two ten,” or twenty. This system is used for higher numbers and more formal contexts.
“20” in Native Korean
In the Native Korean number system, “20” is expressed as 스물 (seumul). This word is entirely different from the Sino-Korean term and is used in different contexts, such as counting objects or stating someone’s age. Remember that Native Korean numbers are typically used for numbers up to 99.
Usage of Sino-Korean and Native Korean Numbers
Knowing when to use Sino-Korean numbers (이십) versus Native Korean numbers (스물) is crucial for accurate and natural communication. Here’s a breakdown of the situations where each system is typically used.
When to Use Sino-Korean Numbers
Sino-Korean numbers are used in a variety of contexts, generally involving larger numbers, measurements, and formal situations. Here are some specific instances:
- Counting money (especially larger amounts): When dealing with significant sums of money, Sino-Korean numbers are preferred.
- Dates (year, month, day): When stating the year, month, and day, use Sino-Korean numbers.
- Phone numbers: Korean phone numbers are read using the Sino-Korean number system.
- Addresses: When giving addresses, Sino-Korean numbers are used for building numbers, apartment numbers, and other numerical components.
- Measurements (length, weight, area): When expressing measurements, Sino-Korean numbers are typically used.
- Minutes and seconds: When telling time, minutes and seconds are expressed using Sino-Korean numbers.
- Numbers with fractions or decimals: Use Sino-Korean numbers when dealing with fractions or decimal points.
- Mathematical calculations: Sino-Korean numbers are used in mathematical contexts.
When to Use Native Korean Numbers
Native Korean numbers are used for counting objects (up to 99), stating age, telling time (hours), and counting people. Here are some specific instances:
- Counting objects (up to 99): When counting items, use Native Korean numbers, but only up to 99. For numbers greater than 99, use Sino-Korean.
- Age: When stating someone’s age, use Native Korean numbers.
- Telling time (hours): When telling the hour, use Native Korean numbers. Minutes and seconds use Sino-Korean.
- Counting people: When counting the number of people, use Native Korean numbers along with the counter 명 (myeong).
- General counting in informal situations: In casual conversations, especially when the numbers are small, Native Korean numbers are often preferred.

- Money: When dealing with larger sums of money, Sino-Korean numbers are preferred. For example, “이십만 원” (isip man won) means 200,000 won.
- Measurements: Use Sino-Korean numbers for measurements such as length, weight, and area. For example, “이십 미터” (isip miteo) means 20 meters.
- Phone Numbers: Phone numbers are always recited using Sino-Korean numbers. For example, “공일공-이십이-삼사오륙” (gongil-gong – isibi – samsaryuk) is 010-22-3456.
- Minutes and Seconds: When telling time, minutes and seconds are expressed using Sino-Korean numbers. For example, “십이시 이십분” (sibisi isip bun) means 12:20.
Native Korean Numbers:
- Age: Always use Native Korean numbers when stating someone’s age. For example, “스물 살” (seumul sal) means 20 years old.
- Counting Objects (up to 99): Use Native Korean numbers when counting objects, but only up to 99. For example, “사과 스물 개” (sagwa seumul gae) means 20 apples.
- Hours of the Day: When telling the hour, use Native Korean numbers. For example, “두 시” (du si) means 2 o’clock. However, this is becoming less common, and Sino-Korean are often interchanged.
- Counting People: When counting the number of people, use Native Korean numbers along with the counter 명 (myeong). For example, “스물 명” (seumul myeong) means 20 people.
It’s important to note that when counting objects beyond 99, you should switch to Sino-Korean numbers. Additionally, when combining numbers with counter words (classifiers), it’s crucial to use the appropriate counter for the specific object being counted.
Common Mistakes When Using Korean Numbers
Learning Korean numbers can be challenging, and it’s common for learners to make mistakes. Here are some frequent errors and how to correct them:
| Incorrect | Correct | Explanation |
|---|---|---|
| 이십 살 (isip sal) | 스물 살 (seumul sal) | Using Sino-Korean for age is incorrect. Use Native Korean. |
| 스물 분 (seumul bun) | 이십 분 (isip bun) | Using Native Korean for minutes is incorrect. Use Sino-Korean. |
| 스물 원 (seumul won) | 이십 원 (isip won) | Using Native Korean for money is incorrect. Use Sino-Korean. |
| 사과 이십 개 (sagwa isip gae) | 사과 스물 개 (sagwa seumul gae) | Using Sino-Korean for counting objects (less than 100) is incorrect. Use Native Korean. |
