Korean numbers: native vs Sino-Korean (full chart 1–100) A1

Two counting systems, one rule for which to use: native Korean (하나, 둘) for hours, age, and counting things; Sino-Korean (일, 이) for minutes, money, dates, and phone numbers. Chart with audio.

The two systems side by side

Korean inherited Sino-Korean numbers from Chinese and kept its own native numbers. Neither replaced the other. You need both, and the choice is decided by what you are counting.

11–99

Native: tens word + unit. 11 = 열하나, 25 = 스물다섯. Tens: 스물 20, 서른 30, 마흔 40, 50, 예순 60, 일흔 70, 여든 80, 아흔 90. Native numbers stop at 99 — nobody says a native 100.

Sino: 십 = 10, so 11 = 십일, 25 = 이십오, 99 = 구십구. Then 100, 1,000, 10,000, 100,000,000. Korean groups by 10,000, not 1,000 — 십만 is 100,000.

Which system, when

Use native forUse Sino for
Hours: 세 시 (3 o’clock)Minutes/seconds: 십오 분
Age (spoken): 스물다섯 살Age (formal/written): 이십오 세
Counting things with counters: 사과 두 개Money: 삼만 원
People: 네 명Dates, years: 구 월 사 일
Times/occurrences: 두 번Phone numbers, floors, bus routes, addresses

Before a counter, four native numbers shorten: 하나→한, 둘→두, 셋→세, 넷→네 (and 스물→스무 before 살). So it is 한 개, 두 명, 세 시, 네 잔.

Pronunciation notes

  • 여덟

    Double batchim ㄼ — said [여덜]; the ㅂ is silent alone.

  • yuk, but after 십 it becomes [심뉵]: 십육 → [심뉵].

  • 스물다섯

    seu-mul-da-seot; ㅡ is flat-lipped. Before 살 use 스물다섯 살 (age 25).

FAQ

Why does Korean have two number systems?

Native numbers are Korea’s own; Sino-Korean numbers came with Chinese characters. Both survived with split roles: native for counting things, hours, and age; Sino for math, money, minutes, dates, and phone numbers.

How do you count to 10 in Korean?

Native: 하나, 둘, 셋, 넷, 다섯, 여섯, 일곱, 여덟, 아홉, 열. Sino: 일, 이, 삼, 사, 오, 육, 칠, 팔, 구, 십.

How do you say your age in Korean?

Native number + 살: 스물다섯 살이에요 (I’m 25). Formal documents use Sino + 세: 25세.

Is 100 native or Sino in Korean?

Sino only — 백. Native numbers stop at 99.
