단어 메모지 Vocabulary Notes

1. 내/제 My

Remember that Korean has two forms of the first-person pronoun I: 저, the humble form and 나, the plain form? The possessive form of the first person pronoun has two versions as well:

First-person Possessive My Example Translation
Humble Form 제 이름은 세영이에요. My name is Seyoung.
Plain Form 내 이름은 세영이에요. My name is Seyoung.

이름              my (-humble) name                              이름            my name

방                  my (-humble) room                              방                my room

2. 학년 School Year

Do you remember Sino Korean numbers that we learned in Preliminaries 2? They can be used together with 학년 (school year) to talk about your year in school. If you want to ask your classmates’ years, you can say “몇 학년이에요 (what year are you [in school])?”

일 학년 freshman           이 학년 sophomore           삼 학년 junior            사 학년 senior

3. 감사합니다/고맙습니다 Thank you

Korean has several versions of “thank you” depending on formality and politeness. Both 감사합니다 and 고맙습니다 are frequently used when you want to say “thank you” politely in Korean. 감사합니다 is a more slightly more formalistic “thank you,” while 고맙습니다 expresses your (slightly more heartfelt) appreciation.

문법과 표현 Recipe

1. Korean WH Questions: … -이/가 뭐예요?   What Is …?

A. WH Question 뭐예요? What is…?

When you make questions in Korean, the question word is not always placed at the beginning of the sentence. Simply replace the word or phrase that you are asking about with the wh- word. The question and answer have the same word order.

가: 전화 번호가 뭐예요?

What’s (your) telephone number?

나: (제 전화번호는) 011에 8500에 4567이에요.

(My telephone number) is 011-8500-4567 (As for my telephone number It’s…)

There are two forms of “what” in Korean. One is 무엇, the full form, and the other is 뭐, the shortened form. 뭐 is used in conversational Korean, and 무엇 usually in written Korean.

Finally, do not forget that the verb has to come at the very end of the sentence, and that you must always have a verb in each sentence!

이름이 뭐예요? What’s your name? NOT 이름이 뭐?

The verb BE is often considered parasitic or “too small,” since it is so short. It also sometimes disappears after a noun ending in a vowel (hence the form ‘예요’). For this reason, this verb is said in one breath along with the preceding noun and is written attached to it. All other verbs in Korean act far more independently, and you do need to put a space between other verbs and their preceding words.


Grammatical subjects in Korean usually introduce some new information. They are marked with -이 when they end in a consonant (like 이메일) and with -가 when they end in a vowel (like 전화번호).

The subject particle 이/가 has other usages, but one function is to mark the subjects of WH-questions, as they seek new information.

1111 가: 이름 뭐예요?                    What’s (your) name?
1111 나: 제 이름 후안이에요.        My name is Juan.
or    나’: 후안이에요.                         (It) is Juan.

As you know, 은/는 is a topic particle, and any noun – even the grammatical subject of the sentence – can be flagged with the topic particle in Korean if what is being discussed is known to both the listener and the speaker. (This is a fine point in the language and you will learn more about it as you go.)


As with your name, when answering with your phone number, you can simply give the information without repeating the word phone number. Where you would say it in English, you don’t need any word in Korea. If you were to repeat the word, you would use the topic particle -은/는, because you are now talking about something as the topic of your discussion.

1111가: 전화번호가 뭐예요?                                       What is (your) telephone number?
1111나: 제 전화번호는 016-7223-4567이에요.       My phone number is 016-7223-4567.
or   나’: 016-7223-4567이에요.                                (It) is 016-7223-4567.

2. Asking For and Reading Dates in Korean


Names of the months are easy in Korean. Simply say the month’s number before the suffix -월, which means ‘moon.’ For ease of pronunciation, the final consonant in the number word is not pronounced.

month month day day
일월 January 칠월 July 일일 the 1st (day) 칠일 the 7th
이월 February 팔월 August 이일 the 2nd 팔일 the 8th
삼월 March 구월 September 삼일 the 3rd 구일 the 9th
사월 April 시월 October 사일 the 4th 십일 the 10th
오월 May 십일월 November 오일 the 5th 십오일 the 15th
유월 June 십이월 December 육일 the 6th 삼십일일 the 31st

Saying the days of the month is just as easy. Just add the suffix -일, which means “day,” after the number. Sometimes you will see a space before 월 and 일 in written Korean, but it makes no difference in meaning.

July 4th          칠 월 사 일                    August 15th  팔 월 십오 일
111111111111   칠월 사일                                              팔월 십오일

B. 며칠 AND 언제 WHEN

When you ask for a date, you can use 며칠 for a specific date. Some people also ask the month: 몇 월 며칠이에요?
11111A: 오늘(이) 며칠이에요?              What’s the date today?
11111B: 사월 오일이에요.                       It’s April 5th .

언제 (when) is also used to ask for a specific date.

11111A: 생일이 언제예요?                          When is your birthday?
11111B: 시월 십일이에요. 오늘이에요.     It is October 10th . It’s today!
11111A: 와, 생일 축하합니다!                     Wow, Happy Birthday! (Lit., Congratulations on your birthday!

연습 3. 한국의 공휴일 (National Holiday)

Listen to your teacher say the month and date for the following holidays and mark them on the calendar.

1) 삼일절 (Independence Movement Day)

2) 어버이 날 (Parents’ Day)

3) 현충일 (Memorial Day)

4) 광복절 (Independence Day)

5) 한글날 (Hangul Day)

6) 크리스마스 (Christmas)

3. -의 (Possessive Particle) and -도 (Also)

A. -도 ALSO

-도 is a noun particle that means too or also. In English, also can occur in several places in the sentence. In Korean, however, -도 must be attached to the new or added noun, which is italicized in the following examples:

저는 1학년이에요. 다미도 1학년이에요.
I am a freshman. Dami is a freshman, too. (Dami, too, is a freshman.)

제 생일은 10월이에요. 친구의 생일도 10월이에요.
My birthday is in October. My friend’s birthday is also in October.


As you already know, the first noun expresses possession of the second noun when two nouns are put together:

111111선생님 전화      teacher’s phone

There is a more obvious way to express possession in Korean, using the possessive particle -의:

111111선생님 전화   teacher’s phone

The possessive particle -의 is used more often in written Korean than in everyday conversation.

누구, which means “who” or “whom,” can be used to ask “whose” questions.

11111가: 누구(의) 우산이에요?   Whose umbrella is it?
11111나: 선생님(의)우산이에요. It’s a teacher’s umbrella.

The possessive form of the humble first person 제 my is often used to answer 누구 + NOUN questions. Note that 제comes from humble I 저 + 의, and the plain form 내 comes from plain I 나 + 의.

plain first person possessive 나 + 의 -> 내
나의 전화번호는 123-9876이에요. My phone number is 123-9876. (written)
전화번호는 123-9876이에요.     My phone number is 123-9876. (spoken)

humble first person possessive 저 + 의 -> 제
저의 친구는 미국 사람이에요.  My friend is American. (written)
친구는 미국 사람이에요.      My friend is American. (spoken)

나 and 저 are never used to mean my even in spoken Korean. You must use 내 and 제!

한국 문화 Korean Flavors

Language Point

Korean Nouns: Plurality

Nouns in Korean are not marked for plurality like in English (e.g. book vs. books).
1111한국어 책이 있어요. I have a Korean book/some Korean books.

To clarify and emphasize that more than one is being talked about, the suffix -들 can be added to the noun, but generally only with animate nouns like “people” or “friends”:
1111한국 친구들이 많아요. I have many Korean friends.

Because 많아요 already means there are many, -들 is rather redundant and often left out: 한국 친구가 많아요. I have many Korean friends.

숫자 Numbers in Korea

Three vs. Four

What numbers do Koreans like? According to a recent survey, Koreans love the number 3, which is believed to bring good fortune. Korean youths even frequently play rock-paper-scissors three times in a row (삼세판). Four, on the other hand, is the number Koreans most dislike, as it is pronounced the same as the Chinese word for dying, 사 (死). In some buildings, the 4 th -floor button in elevators is replaced with “F” (four), and you won’t ever see 4444 in license plates or business telephone numbers!

Korean businesses take advantage of certain number combinations that sound like words. The following are some popular phone numbers that Korean business owners pay extra fees to own. Can you guess what types of businesses the following numbers are used for?

2424 이사이사          (이사하다 = to move)
8282 팔이팔이          (빨리 = quickly)
1004 천사                   (천사 = angel)

Answer: moving company        delivery service           charity donation center

Year in School vs. Student Number

Korean college students often ask peers for their “학번” as in “학번이 뭐예요?” If a college student’s 학번 is 20 학번, they entered college in 2020. As many male students fulfill their two-year military service during college, 학번 is a more accurate indicator of one’s seniority than 학년 (year in school).

할 수 있어요! I got this!

1rCheck to see if you can do the following.

  • I can exchange personal contact information in Korean.
  • I can ask and answer “what” questions in Korean.
