Korean numbers 1 to 100

Both systems, every number, with the romanization under each word. Sino-Korean runs the whole way to 100; native Korean ends at 99.

How 11 to 99 are built

Sino-Korean multiplies and adds. A digit before 십 sip counts the tens, a digit after it adds the units: 십일 sibil is ten and one, 이십 isip is two tens, 사십칠 sasipchil is four tens and seven. Ten itself is 십 sip, not 일십.

Native Korean has a separate word for each ten and puts the unit straight after it, with no space: 열하나 yeolhana is 열 yeol and 하나 hana, 마흔일곱 maheunnilgop is 마흔 maheun and 일곱 ilgop. Written as one word either way.

The tens side by side

This is the part of the table where the two systems part company. Sino-Korean tens are predictable; native tens have to be learned one by one.

Where learners slip

Six. Written 육 yuk everywhere, including 십육 simnyuk and 육십 yuksip. The sound changes after a consonant (simnyuk, baengnyuk for 106), so learners sometimes write what they hear. The pronunciation page sets out why.
Eight. Native 여덟 yeodeol ends in the double consonant ㄼ, of which only the ㄹ is heard. It is the native number most often misspelled.
Forty and four. 마흔 maheun and 넷 net share nothing. Some tens echo their unit (여든 and 여덟, 아흔 and 아홉, 일흔 and 일곱), but the echo is too loose to build the tens from, and 스물, 마흔 and 쉰 show none at all.
Mixing systems inside one number. 스물셋 and 이십삼 are both 23; 이십셋 is neither.

For classroom practice, the worksheet generator makes sheets in either system at 1 to 99 or 1 to 100, with every decade on each sheet and the answer key as a separate file.

Questions teachers and learners ask

How do you say 100 in Korean?

100 is 백 (baek), Sino-Korean, with no 일 in front. There is no native Korean word for 100 in modern use, so even a native count that reaches 아흔아홉 (99) carries on with 백. 101 is 백일, with the zero in the tens place simply left out.

Why are there two words for 20?

Because each system has its own: 이십 is Sino-Korean (two tens) and 스물 is native Korean. Which one you use depends on what the number is for. You are 스무 살 (20 years old), but it is 이십 분 (20 minutes) and 이십 일 (the 20th of the month).

Is 16 pronounced the way it is spelled?

Not quite. 십육 is spelled with the parts 십 and 육, but it is said [심뉵], simnyuk: an n sound is added before 육 and the p of 십 turns to m in front of it. The same happens in 26, 36 and so on up to 96, and in 106. The spelling stays 육 throughout; only the sound changes.

Which is easier to learn first, Sino-Korean or native 1 to 100?

Sino-Korean, for most learners. Once you know nine digits and 십, every number to 99 follows: 칠십삼 is seven tens and three. Native Korean needs nine separate words for the tens, and they do not look like the units (마흔 for 40 shares nothing with 넷 for 4), so it takes longer to learn all the way to 99.
