Understanding how to count is the first step toward fluency in any language, and Korean is no different. The system for Korean numbers, known as Sino-Korean, is logical and structured, built upon a base-10 framework that makes large numbers easy to grasp. This guide provides a complete breakdown of numbers 1 through 100, helping you move from simple counting to confident usage in everyday situations.
Foundations of Sino-Korean Numbers
Unlike the native Korean number system used for counting objects and telling time on a 12-hour clock, Sino-Korean numbers are derived from Chinese numerals. This system is used for dates, money, phone numbers, and any situation where precision is key. The beauty of these figures lies in their consistency; once you learn the words for 1 through 10 and the words for ten, hundred, and thousand, you can construct almost any number.
The basic building blocks are as follows: one is "하나" (hana), two is "둘" (dul), and three is "셋" (set). However, when combining these with multiples of ten, you will primarily use the Sino-Korean versions: 일 (il), 이 (i), 삼 (sam), 사 (sa), 오 (o), 육 (yuk), 칠 (chil), 팔 (pal), 구 (gu), and 십 (sip). This distinction is crucial for mastering the language, as you will switch between the two systems depending on the context.
Numbers 1 to 10
To build a strong foundation, you must start with the essentials. The numbers 1 through 10 in Sino-Korean are the pillars upon which all larger numbers are constructed. Pronunciation is key here, as some sounds change depending on their position in a word, but the written forms remain stable.
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)
Tens and Compound Numbers
Once you reach 11, the logic of the language becomes apparent. Instead of having a unique word for every number, you combine the tens place with the ones place. For example, 11 is "십일" (sip-il), meaning "ten one." This pattern continues seamlessly through the teens and into the higher decades, making it easy to count on your fingers if you know the basic components.
When a number like two appears in the tens place, it changes from "둘" (dul) to "이" (i), resulting in "이십" (isip) for twenty. Similarly, three becomes "삼" (sam), making "삼십" (samsip) for thirty. This predictable pattern holds true all the way up to 99, allowing for quick mental calculations and easy memorization.
Numbers 20 to 100
After mastering the teens, you move into the twenties and beyond. The structure remains the same: the tens digit comes first, followed by the units digit, with no connector needed. For instance, 21 is "이십일" (isip-il), and 30 is "삼십" (samsip). This consistency is what makes the Korean number system so powerful and efficient for learners.
