Verbs - Polite [Present, Past]

Polite Form 

This lesson is about the polite form of verbs, in addition to the informal form which we learned in the previous lesson. Let's go over again the differences between the informal and polite forms.

  • Informal - Generally speaking, the informal form is used among people of the same age or to people who are younger by older people. It is also used by people who are closely related such as such family members and relatives. People who are close friends would use this form depending on the familiarity and acceptability.

  • Polite - The polite form is used when speaking to people who are older than you or of a higher rank than you such as in the company, army and other institutions. However, people generally use the polite form in many social settings regardless of one's age. Initially, it would be best to stick to the polite form when learning Korean, as this would be the predominant form of speaking to people in many social environments. However, if you attend school or other similar institutions where you'd make friends and the environment is more casual, it might be more appropriate to use the informal form.


Note: The words in bold indicate which of the two negatives are more commonly used in each case, i.e. 먹지 않습니다 is more commonly used than 안 먹습니다 in the written form, and 안 먹어요 is more commonly used than 먹지 않아요 in the spoken form.

Conjugation Rules

I) Informal Plain Polite Present (Written)

First of all, take 다 off the plain form of verbs, and then:

1. For verbs whose final character has no final consonant, add ㅂ 니다.

E.g.
  • 하다 → 합니다 = do
  • 가다 → 갑니다 = go
  • 오다 → 옵니다 = come
  • 쓰다 → 씁니다 = write 
  • 말하다 → 말합니다 = speak
  • 바라다 → 바랍니다 = hope 
  • 자라다 → 자랍니다 = grow

    2. For verbs whose final character has a final consonant, add 습니다.

    E.g.

    • 걷다 → 걷습니다 = walk
    • 듣다 → 듣습니다 = listen
    • 읽다 → 읽습니다 = read
    • 입다 → 입습니다 = wear

    Note: The rule 3 overrides the rule 2.


      3. For verbs whose last character has ㄹ as a final consonant, change it to ㅂ and add 니다.
       
      E.g. 

      • 살다 → 삽니다 = live
      • 놀다 → 놉니다 = play (have fun)
      • 알다 → 압니다 = know
      • 날다 → 납니다 = fly

      • 말다 → 맙니다 = roll (up) 
      • 밀다 → 밉니다 = push


      II) Informal Past Polite Past (Written)

      Take 다 off the informal past form of verbs, and then add 습니다.

      • 했다 → 했습니다 = did
      • 갔다 → 갔습니다 = went
      • 왔다 → 왔습니다 = came
      • 봤다 → 봤습니다 = watched 
      • 먹었다 → 먹었습니다 = ate
      • 달렸다 → 달렸습니다 = ran
      • 만났다 → 만났습니다 = met


        III) InformalPolite (Spoken)

        Just add 요 to the informal spoken forms.

        • 해 → 해요 = do
        • 가 → 가요 = go 
        • 와 → 와요 = come
        • 안해 → 안해요 = not do
        • 안봐 → 안봐요 = not watch
        • 안사 → 안사요 = not buy
        • 안자 → 안자요 = not sleep
        • 먹었어 → 먹었어요 = ate
        • 걸었어 → 걸었어요 = walked
        • 만났어 → 만났어요 = met
        • 안했어 → 안했어요 = didn't do
        • 안갔어 → 안갔어요 = didn't go
        • 안먹었어 → 안먹었어요 = didn't eat
        • 안빌렸어 → 안빌렸어요 = didn't borrow


        A brief revision of the differences between the written and spoken forms

        • The written form is used in literature such as books, newspapers and any form of writing that is not 'conversational.' The written form, in essence, is literary, factual and declarative. It is rarely used in normal everyday conversations. However, the news on TV uses this written form of Korean. It is also used in public speeches. The reason is probably due to the fact that the news and public announcements or speeches are usually all declarative and/or factual.

        • The spoken form is the usual way in which people speak and have a conversation. It is used in all types of spoken Korean such as normal conversations, dramas, and movies, with the possible exceptions of news, documentaries and other factual, formal types of programs on TV and radio.

          Verbs - Descriptive Form II

          The descriptive form II of verbs takes the meaning of "~ed." (ie. past tense) or is used as a past tense clause involving "who, which, that etc.".

          Die
          죽다
          죽은
           
          Verbs can be used in front of nouns to describe them, and form a past tense clause involving "who, which, that" of English. For example, the descriptive form II of 떠나다 is 떠난 and 떠난 기차 means a "train which left". Literally, 떠난 means "left" therefore 떠난 기차 = a left train

          ● Rules 

          First, take 다 off a verb and then, 

          1. For verbs with a final consonant, add 은

          Eg.
          • 먹다 → 먹은 = ate
          • 사과 먹은 난쟁이 → a dwarf who ate an apple
          • 죽다 → 죽은 = died/dead

          • 믿다 → 믿지 않은 = disbelieved
          • 믿지 않은 토마스 → Thomas who disbelieved
          • 읽다 → 읽은 = read (past tense)
          • 읽은 기사 → an article that I read 

          2. For verbs without a final consonant and verbs with ㄹ as a final consonant, replace it with ㄴ as a final consonant.

          Eg.
          • 빌리다 → 빌린 = borrowed
          • 빌린 책 → a book which I borrowed (Lit. a borrowed book)
          • 쓰다 →쓴 = wrote
          • 성루까가 쓴 복음 = the gospel which St. Luke wrote
          • 멈추다 → 멈춘 = stopped

          • 주님을 기다리지 않은 하인 → a servant who didn't wait for the Lord
          • 먹다 → 먹지않은 = didn't eat
          • 음식을 먹지 않은 개 = a dog who didn't eat food
          • 포기하다 → 포기하지 않은 = didn't give up
          • 끝까지 포기하지 않은 욥 = Job who didn't give up till the end

          Verbs - Contiunous

          Continuous Form [~고 있다]

          In this lesson, we'll learn about the 'continuous' form. It would be similar to the '-ing' form in English.


          Informal Written Form Plain Form
          Present Continuous
          Positive 하다 하고 있다
          Negative 하지 않다
          안 하다
          하지 않고 있다
          안 하고 있다

          • 하다 = do
          • 하지 않다/안 하다 = not do
          • 하고 있다 = is doing
          • 하지 않고 있다/안 하고 있다 = is not doing

          Note: The bold letters indicate which of the two alternatives in the negative form is more commonly used in the written form, i.e.:
          • 하지 않다 is more commonly used than 안 하다 in written Korean.

          Informal Written Form Past Past Continuous
          Positive 했다 하고 있었다
          Negative 하지 않았다
          안 했다
          하지 않고 있었다
          안 하고 있었다

          • 했다 = did
          • 하지 않았다/안 했다 = didn't do
          • 하고 있었다 = was doing
          • 하지 않고 있었다/안 하고 있었다 = wasn't doing


          Conjugation Rules

          Take 다 off the plain form of verbs, and then add 고 있(었)다 for their positive form and 지 않고 있(었)다 for their negative form.

          E.g.
          • 쓰다 → 쓰고 있다 = is writing
          • 피터는 편지를 쓰고 있다 = Peter is writing a letter.

            • 나눠주다 → 나눠 주고 있다 = is serving/distributing
            • 보영은 아이들에게 학교급식을 나눠주고 있다 = Bo-young is serving school meals to children.

                • 듣다 → 듣고 있었다 = was listening
                • 폴은 팀 켈러의 메세지를 듣고 있었다 = Paul was listening to a Tim Keller's message.

                          Negative

                          • 하지 않고 있어/안 하고 있어 = is not doing
                          • 하고 있었어 = was doing
                          • 하지 않고 있었어/안 하고 있었어 = was not doing


                          The conjugation rule is the same as the written form except 다 at the end of sentences changes to 어.

                          • 점심 먹고 있어 = I am eating lunch
                          • 줄리아는 안 달리고 있어 = Julia is not running

                          Polite Form

                          While the informal form in the examples above is used by people who are of the same age and/or close, or when older people are talking to younger people in informal situations, the polite form is commonly used by younger people addressing older people, and in any formal situations.

                          These descriptive forms I are used in front of nouns to describe them, and form a present tense clause involving "who, which, that" of English. For example, the descriptive form I of 가다 is 가는 and 가는 기차 means a "train which goes". Literally, 가는 means "going" therefore 가는 기차 = a going train.

                          ● Rules 

                          First, take 다 off a verb and then, 

                          1. add 는

                          Eg.

                          2. Take ㄹ off a verb with a final consonant, ㄹ and add 는.

                          Conjugation rules

                          First of all, take 다 off the plain form of verbs and then:

                          I) Will

                          1. For verbs whose final character has no final consonant, attach ㄹ 거다 to them.

                          E.g.
                          • 하다 → 할 거다 = will do

                          • 앉다 → 앉을 거다 = will sit

                          3. For verbs whose final character has ㄹ as a final consonant, just attach 거다 to them.

                          E.g.

                          • 밀다 → 밀거다 = will push

                          II) Won't

                          Simply attach 지 않을 거다 to verbs.

                          E.g. 

                          • 하다 → 하지 않을 거다 = won't do
                          • 가다 → 가지 않을 거다 = won't go

                          Let's briefly go over the differences between the informal and polite forms again.

                          While the informal form in the examples above is used by people who are of the same age and/or close, or when older people are talking to younger people in informal situations, the polite form is commonly used by younger people addressing older people, and in any formal situations.


                          Polite Written Form
                          Will do
                          Won't do

                          하지 않을 겁니다
                          안 할 겁니다

                          Polite Spoken Form
                          Will do
                          Won't do

                          할 거예요
                          하지 않을 거예요
                          안 할 거예요


                          Note: The bold letters indicate which of the two alternatives in the negative form is more commonly used in each of the written and spoken forms, i.e.:

                          • 하지 않을 겁니다 is more commonly used than 안 할 겁니다 in written Korean.
                          • 안 할 거예요 is more commonly used than 하지 않을 거예요 in spoken Korean.

                                  Verbs - Have

                                  Have (있다) / Don't have (없다)

                                  This lesson covers how the verb, 'have', is used. It can be expressed in two ways:

                                  • 있다 = there is/are (Lit. is present)
                                  • 가지고 있다 = have, possess
                                  • 없다 = there isn't/aren't (Lit. is not present)
                                  • 가지고 있지 않다 = do not have/possess

                                  Informal Written Form Have Don't have
                                  있다 없다

                                  가지고 있다 가지고 있지 않다
                                  안 가지고 있다

                                  Informal Spoken Form Have Don't have
                                  있어 없어

                                  가지고 있어 가지고 있지 않아
                                  안 가지고 있어

                                  Note: The words in bold letters are the more commonly used of the two alternatives in each of the Written and Spoken forms.


                                  Have (있다)

                                  있다 means 'there is/are', for example:

                                  • 정원에 강아지가 있다 = There is a puppy in the garden.
                                  • 책상 위에 개미가 있다 = There's an ant on the desk.

                                  However, 있다 can also mean 'have'. It is used more frequently than the alternative, '가지고 있다', which is more cumbersome to pronounce.

                                  • Written form → 있다, 가지고 있다
                                  • Spoken form → 있어, 가지고 있어


                                  Example Sentences

                                  Written Form
                                  • 책이 있다. = I have a book. (Lit. There is a book)
                                  • 시계가 있다. = I have a watch.
                                  • 핸드폰이 있다. = I have a mobile phone.
                                  • 책을 가지고 있다. = I have a book.
                                  • 핸드폰을 가지고 있다. = I have a mobile phone.

                                  Spoken Form
                                  • 책(이) 있어.
                                  • 핸드폰(이) 있어.
                                  • 시계(가) 있어.
                                  • 책(을) 가지고 있어.
                                  • 핸드폰(을) 가지고 있어.

                                    Note: 1. Use 이/가 with "있다" and 을/를 with "가지고 있다".
                                              2. The particles are usually omitted in spoken Korean.


                                    When you say, 'I have a brother or sister', 가지고 있다 CANNOT be used because it implies ownership. Only 있다 can be used in relation to people. 

                                    For example,

                                    Written Form
                                    • 남동생이 있다. = I have a younger brother.
                                    • 여동생이 있다. = I have a younger sister.

                                    Spoken Form
                                    • 형(이) 있어. = I have an older brother.
                                    • 누나(가) 있어. = I have an older sister.
                                    • 남동생(이) 있어. = I have a younger brother.
                                    • 여동생(이) 있어. = I have a younger sister.


                                    Don't have (없다)

                                    없다 literally means 'there isn't/aren't'. However, it can also mean 'don't have'

                                    For example,

                                    Written Form
                                    • 없다 = don't have (Lit. there isn't/aren't)
                                      • 가지고 있지 않다/안 가지고 있다 = don't have (Lit. don't own/possess)

                                        Spoken Form
                                        • 없어 = don't have (Lit. there isn't/aren't)
                                          • 가지고 있지 않아/안 가지고 있어 = don't have (Lit. don't own/possess)

                                          Note: For the negatives, the words in bold letters are the more commonly used of the two alternatives in each of the Written and Spoken forms.

                                          Question Form

                                          In spoken Korean, in order to change a sentence into a question, you simply need to raise your tone at the last letter.

                                          To see how it's done, it'd be probably best to watch a native Korean do it for you. However, as I figure most of you would not have that kind of luxury, having a native speaker do it for you whenever you want, I encourage you to listen to the Korean audios or recordings online or watch Korean dramas or movies and familiarize yourself with the intonation of questions.

                                                        ● A list of written forms and their respective spoken forms.

                                                        Verbs - Present, Past

                                                        동사 [Verbs]

                                                        Now, we come to learn, possibly, the most important subject of all Korean grammar, the 'verbs.'

                                                        I have drawn up tables below to display various conjugations of verbs. But first of all, we need to pay attention to a distinct feature in Korean verbs, namely, the plain form.

                                                        The plain form is the most basic form of verbs, from which all the other conjugations of verbs are derived and produced.

                                                        However, the plain form is almost never used in both written and spoken Korean. The only instance where the plain form is used is when verbs are listed in the dictionary. Therefore, it is necessary to know the plain form if you'd like to know the meaning of certain verbs and find them in the dictionary.

                                                        Examples of the plain form of verbs

                                                        • 하다 = do
                                                        • 먹다 = eat
                                                        • 가다 = go 
                                                        • 달리다 = run
