The intriguing complexity of the Korean language goes beyond its unique script, Hangul, and its rich vocabulary. Indeed, one of the most fascinating elements of this language comes from its dual number systems, the Sino-Korean and Native Korean. To fully grasp the usage of these systems, one not only needs to familiarize himself with the numeric symbols and their pronunciation but also understand their applications in various contexts such as age, money, dates, and timekeeping among others. As such, this exploration begins with a brief overview of these two number systems and their practical utilization.
Understanding the Two Number Systems
Korean Number Systems: An Overview
There are two main number systems used in Korean, which are Sino-Korean and Native Korean. The Sino-Korean system is derived from Chinese and is utilized primarily for dates, money, addresses, phone numbers, and numbers above 100. On the other hand, the Native Korean system handles numbers from 1-99 and is commonly used for denoting age, hours, and counting objects.
Understanding Sino-Korean Numbers
This system primarily derives from Chinese numerals and finds its use in certain aspects of daily life. The basic numerals for Sino-Korean system 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), and 10 – 십 (ship).
It’s imperative to understand the basis of this system as it’s frequently used to express money, dates, and large numbers. For example, to understand Korean won (money), one must recognize how the Sino-Korean number system works. Dates are also spoken in this particular system, making it vital for people learning Korean.
Grasping Native Korean Numbers
The Native Korean number system is used for numbers from 1-99, counting objects, amounts, and hours. The fundamentals of this system 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), and 10 – 열 (yeol). For numbers 20, 30, 40 and so forth, you just add the native Korean number to 열 (yeol). For example, 20 is 스물 (seumool), 30 is 서른 (seoreun) and so forth.
Usually, when you state your age, you will use the Native Korean number system. Similarly, this system is used when stating the time. A critical aspect to note is, when counting objects or people, you must use a correct counting word after the number. Different objects may require different counting words.
Navigating the Two Systems
In day-to-day use, you will come across both these systems in Korea. While it may be challenging to navigate between the two systems initially, practice and consistent exposure will help. Remember, Sino-Korean is prominent for dates, money, addresses, phone numbers, and large numbers, while Native Korean dominantly caters to numbers from 1-99, hours, and objects. Therefore, figuring out where each system is used is the first step to acing Korean numbers.

Practicing Pronunciation of Korean Numbers
Learning Basics of Korean Numbers System
The Korean language features two sets of numbers, the native Korean numbers and the Sino-Korean numbers. Sino-Korean numbers are derived from Chinese numbers and are used to express dates, measurements, money, phone numbers, and other things involving units or counts. The native Korean numbers are used for quantities up to 99, age, hours, and for counting objects/instances.Pronouncing Sino-Korean Numbers
Begin by familiarizing yourself with the Sino-Korean number system. Here are the first ten numbers to start practicing:- 일 (il)
- 이 (yi)
- 삼 (sam)
- 사 (sa)
- 오 (o)
- 육 (yuk)
- 칠 (chil)
- 팔 (pal)
- 구 (gu)
- 십 (ship)
Pronouncing Native Korean Numbers
Then switch to the native Korean numbers. Similar to the Sino-Korean numbers, start with the first ten:- 하나 (hana)
- 둘 (dul)
- 셋 (set)
- 넷 (net)
- 다섯 (daseot)
- 여섯 (yeoseot)
- 일곱 (ilgop)
- 여덟 (yeodeol)
- 아홉 (ahop)
- 열 (yeol)
Forming Larger Numbers
For numbers beyond 10, both systems use the base numbers one through ten to form larger numbers. For example, in Sino-Korean, 15 would be 십오 (ship-o), combining the words for “ten” and “five.” In native Korean, 15 would be 열다섯 (yeol-daseot), following the same logic.Advanced Practice Tips
Consider recording your voice as you practice and listen to it afterwards to ensure your pronunciation is accurate. There are many online resources, including pronunciation guides and native speaker videos, that can assist you in honing your skills. Remember, practice is the key to perfecting your Korean numbers pronunciation.
Applying the Use of Korean Numbers
Understanding the Two Korean Number Systems
In the Korean language, there are two different numbering systems – the ‘Native Korean numbers’ and the ‘Sino-Korean numbers’. The Native Korean numbers, also known as ‘Pure Korean numbers’, are unique to the Korean language and used for numbers from 1 to 99. The Sino-Korean numbers, on the other hand, are derived from Chinese and are used for higher numbers and counting units.
Mastering the Native Korean Numbers
Native Korean numbers are typically used when you’re counting from 1-99 without a specific unit of measure attached. Memorize the numbers from 1 to 10 and understand the structure of the numbers from 11 to 99 to master this number system. For instance, the number ’15’ would be 이나는 for fifteen (십오) in Sino-Korean, and 열다섯 for fifteen (열다섯) in Native Korean.
Getting Comfortable with The Sino-Korean Numbers
The Sino-Korean number system is used for dates, measurements, defining the digits or telling phone numbers, giving your age, or dealing with money. Essentially, for this system you only need to memorize the numbers from 1 to 10, as well as the units for tens, hundreds, thousands, tens of thousands, etc. which are simply combined. For example, 25 in Sino-Korean, would be 이십오 (이 means 2, 십 means 10, 오 means 5).
Expressing Your Age in Korean
When expressing your age, you generally use the Sino-Korean number system. If your age is 25, for instance, your age in Korean would be 이십오 살 (이십오 means 25, 살 means years old).
Telling Time in Korean
When telling the time, Koreans use both numeral systems. The hours are represented using the Sino-Korean numbers, whereas the minutes are represented using the Native Korean numbers. However, the exception is when a number from 1 to 30, in this case, either system could be used. For example, 3:15 would be 세 시 십오 분 (세 means 3 in Native Korean, 시 means hour, 십오 means 15 in Sino-Korean, 분 means minute).
Numbers in Daily Life: Phone Numbers
When expressing phone numbers in Korean, you use the Sino-Korean number system. Each digit is said one by one. For instance, a phone number like 123-4567 would be 일이삼-사오육칠팔 in Korean (일 for 1, 이 for 2, 삼 for 3, 사 for 4, 오 for 5, 육 for 6, 칠 for 7).
Remember, the secret to mastering Korean numbers is practice!
Incorporate the usage of these numbers in your daily life and see how quickly you’ll be able to count and express various numbers in Korean!
