2 different system of cardinal numbers
There are 2 different system of cardinal numbers in Korean -- one derived from Chinese characters, in other words, Sino-Korean, and the other from native Korean. Koreans use one of them based on the situation.
1. Native Korean numbers exist only from 1 to 99. If the number is either 0 or above 100, Koreans only use the Chinese character system of numbers.
2. Native Korean numbers are usually used when you count something or say someone's age or hours.
□ 나는 다섯 살입니다.
- naneun dah-sut sahrimnida.
- I am five years old.
□ 지금 두 시입니다.
- jigeum du shi-imnida.
- It's two o'clock.
Chinese oriented numbers are used for dates, money, minutes and seconds, addresses, and phone numbers.
□ 오늘은 이 월 구 일입니다.
- ohneureun ee wol goo yeerimnida
- It's February 9 today.
