Level 1 Lesson 15 / Sino-Korean Numbers / 일, 이, 삼, 사 ….

In this TTMIK lesson, we are talking about numbers. In Korean there are two sets of number, one is native Korean numbers and the other set is sino-Korean numbers. Sino-Korean numbers are numbers that are based on the Chinese language (therefore if you speak Chinese, you will find that the sino-Korean numbers are quite similar to the Chinese numbers), and in this lesson we are introducing numbers 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 100, and 1,000.

Numbers are not always easy to memorize, especially if you don’t have to use them often, so be sure to practice using them every chance you get!

Level 1 Lesson 15 / Sino-Korean Numbers / 일, 이, 삼, 사 ….

    I think numbers work the same way as in Chinese (I’m learning Chinese in school this year) so it makes sense! But I keep accidentally switching between Korean and Chinese haha

  • Cookie

    Thank you! Your way of teaching is really good! 감사합니다! How do I say a mobile phone number? Do I just say all the numbers separately or do I put them together? For example 1234. Would it be 1-2-3-4 or 12-34? I hope you know what I mean! 🙂

    • Setsuna

      Not a teacher or anything but i’m pretty sure you just say it number by number just like anywhere else. Maybe not the best comparison, but we Japanese people also say it number by number so.

    • Jayhee Kim

      You say the individual numbers.
      010-5321-0173 = 공일공[에] 오삼이일[에] 공일칠삼. The hyphen is pronounced like 에 but you can drop it because it gets really repetitive and dull-sounding lol. Kind of like Americans say their numbers without the dash but instead use a space between the numbers, Koreans use 에.

  • Suga Swag

    795 칠백구십오
    421 사백이십일
    16 십육
    24 이십사
    3793 삼천칠백삼

    Am I correct?

    • JooyeonPark

      They are all good but the last one. It should be 삼천칠백구십삽.

  • krysolov

    For pronunciation, are the combined numbers treated as one word with all the corresponding sound changes?
    33 – 삼십삼 [삼십쌈]
    639 – 육백삼십구 [육빽쌈십꾸]

    Listening to this and the Lv 2/12 (dates) lessons I clearly heard the movement of the 받침 if the following number starts with ㅇ, and I thought I heard the tensification, but i don’t think my ears are fully trained yet to clearly recognize that.

  • Hero

    This was my practice

    912 구백십이
    227 이백이십칠
    552 오백오십이
    3219 삼천이백일십구

    For 3219 the 3(삼) goes before 1000(천) like above correct?

    감사합니다! ^^

  • 423 사백이십삼
    87 팔십칠
    6986 육천구백팔십육
    155 백오십오
    7034 칠천삼십사

    Correct? 감사합니다~

  • Amber Woods

    감사합니다 ~Thank you ^u^

  • 4 = 사
    94 = 구십사
    994 = 구백구십사
    1994 = 천구백구십사

    How do I say, “iKON has 7 members.”? Is it “아이콘 칠 멤버들 있어요.”?

  • Raven Gonzales

    So is it better to learn Sino-Korean numbers or Native?

    • Ikraan Hassan

      Both are equally importent

    • Raven Gonzales

      Thank you!


    6794 육천칠백구십사
    57 오십칠
    4203 사천이백삼
    Am I correct?

  • Semitic akuma

    btw the comments on the previous lesson is closed
    so you know 🙂 you are welcome keke~

  • Maya Rijkelijkhuizen

    23 -> 이십삼
    411-> 사백십일
    808 -> 팔백팔
    1500 -> 천오백
    1345 -> 천삼백사십오
    76 -> 칠십육
    88 -> 팔십팔
    101-> 백일
    1189 -> 천백팔십구
    184 -> 백팔십사
    2200 -> 이천이백

    Are these correct?

    • Mario Super

      Yes they are correct. Well done. But there is one exception that is the same in English, and that’s addresses and phone numbers. Those numbers would all be said as separate numbers.

  • Bushra

    is it okay to buy the workbooks without buying the lesson books??

  • Sabeur safaa

    This is the most wonderful course I had in my entier life ! ( 18 years of studies ) 😀 Thank you ! you really made my day !

  • Miumiu

    Im from Hong Kong and i speak cantonese. This lesson is quite easy for me as the numbers have the same pronunciation! And so i’m also excited when having this lesson! THANK YOU!

    • Kenny Lau

      I speak Cantonese also, and I think that Taiwanese/Hokkien/Amoy numbers (the literal version) are more similar to the Korean numbers.

  • Kenny Lau

    It might be worth mentioning that people avoid saying the number 18 in the Sino-Korean numeral system because it sounds like the f-word 씨발.

  • Colleen Chen

    Thank you for sharing!

  • nathalie

    십삼 = 13
    삼천십일 = 3011
    일천삼 = 2003

    • 신 켄넷

      You forgot that 일 is one lol
      Should be 이

  • Sana ShyShyShy

    I learn a lot in this lesson. Personally I think forming Korean 숫자 is easier than 영어 숫자 because you add. “eleven” how was that even made?
    Anyways- 감사합니다~ 이 Lesson 정말 재미 있어요~
    안녕히 계세요~~

  • Tyka Amanda

    일 찬 교십이 = 1992
    이십발 = 27
    일 = 1
    이챤 일십욕= 2016
    일십욕 = 16
    십 삼 = 30

    this is correct ??

    • 신 켄넷

      1992 should be:
      천 구백 구십 이

      27 is correct but 7 is 팔 and not 발

      2016 should be:
      이천 십륙 / 이천 십육 (I’m not sure about 육 and 륙. It’s the same but has a rule)

      16 is 십육/십륙 (again, the 륙 and 육…)

      And 30 is 삼십

      So technically you didn’t get any correct answer…
      You still need to review this lesson. But don’t feel bad about it. You can do it. Just review a bit more and you’ll be fine 🙂

    • Simay

      I think it’s “십육” since the “ㅇ” doesn’t have a sound when it is used as a top consonant. And probably trying to make a “ㄹ” sound will be hard when it is used at the top after any consonants. But I’m not sure tbh.

    • Kirstin Traylor

      wouldn’t 27 be 이십칠? 팔 is 8

  • 신 켄넷

    So 100,547 is
    백천 오백사십칠?
    Idk why I’m trying to get complicated lol
    But I do think and feel like I understand this lesson well….

    Or do I?

    • Chinkee Padua Motas

      십만 오백 사십 칠

      there is no thing as 백천

      hundred thousand in korean is 십만 (ten 10,000)

  • Yanesya Lastika

    So if 10.000 is 만 100.223 is 십만시백시십삼? (CMIIW)
    what is 500.000? Should I say 50 + 10.000? (오십만)
    And what is the korean of “million” and “billion”?
    Thanks ^^

    • Anne Whoknows

      백만 – million
      천만 – 10 000 000
      억 – 100 000 000

  • Chichi Arquisola

    I am grateful for you guys! Learning is so much fun with TTMIK! I learn 한글 when I’m stressed. That should mean I’ve having lots of fun learning. 감사합니다!

  • Kirstin Traylor

    So 1991 is 천구백구십일
    and 2017 is 이천십칠 Right?

  • chemicent

    If 육 was at the beginning of a number (654) would it be 육 or 륙?

  • Shirogane

    They sound really similar to japanese 1-9

  • Danica

    So every time i combine nuuhmbers i just put십 in the middle??

    • Janene Simte

      The combination of numbers are made with number place value. The term shib is used for the ten place value, for example: 73, seven + ten (since 70 is ten place value) + three as Chil Shib Sam

  • Alex

    This sort of reminds me of French except it’s more logical/consistent.

    18 = 10 + 8
    88 = 8 + 10 + 8
    98 = 9 + 10 + 8

    Cool, that makes sense!

    18 = 10 + 8
    88 = 4 + 20 + 8
    98 = 4 + 20 + 10 + 8

    Why France… Why are you doing this to me…

    • mengshachen

      Quick nitpick for mathematical accuracy 🙂
      In French, 88 is 4 * 20 + 8 and 98 = 4 * 20 + 10 + 8

      Yeah it was a pain when I first started learning French but after years of use the numbers just roll off the tongue without me thinking about it or the maths behind it. That’s where I hope to achieve with Korean!

  • Janice

    so would 989,898 be 구십팔만구천팔백구십팔?
