Saying Sino-Korean numbers in Korean
The Korean language has two counting systems - the first being a native Korean counting system, the second is based on the Chinese counting system.
Today, we introduce the Sino-Korean counting system:
1 일 [il]
2 이 [i]
3 삼 [sam]
4 사 [sa]
5 오 [o]
6 륙 [ryuk] / 육 [yuk]
7 칠 [chil]
8 팔 [pal]
9 구 [gu]
10 십 [sip]
And the rest, as they say, is easy.
In Korean, if you want to say 11, you just say TEN + ONE.
If you want to say 33, you just say THREE + TEN + THREE.
If you want to say 99, you say NINE + TEN + NINE.
