The passive voice is a grammatical voice in which the subject receives the action of a transitive verb. Passive voice emphasizes the process rather than who is performing the action. In Korean this form is called 피동. There are few patterns to help distinguish between active and passive voices in Korean verbs. This makes this more difficult to learn than a regular Korean grammar rule.
Passive verbs still work as action verbs but now the object (that usually takes 을 or 를) has become the subject of the sentence (takes the particles: 이 or 가).
- 길을 막아요. [Traffic] blocks the road.
- 길이 막혀요. The road is blocked [by traffic]. (막히다 is much more common in this scenario)
Many active voice English expressions should be translated to the passive form in Korean. (Only using the passive form is natural in Korean.)
- It looks fine. ☞ 괜찮아 보여요. [It] is seen to be fine.
- It sounds like English. ☞ 영어처럼 들려요. [It] is heard like English.
- I can't see the blackboard well. ☞ 칠판이 잘 안 보여요. The blackboard is not seen well (by me).
- Can you hear my voice? ☞ 내 목소리 들리냐? Is my voice heard (by you)?
- The game has begun. ☞ 게임이 시작되었다. The game has been begun. (A game can't begin something because it has no ability to decide. There must be a human who had decided to begin the game. The "game" is passive, not active.)
- This book is selling very well. ☞ 이 책은 아주 잘 팔리고 있다. This book is being sold very well. (A book can't sell something because it's not a human. The "book" is passive, not active.)
- The door is opening. ☞ 문이 열리고 있다. The door is being opened. (A door can't open something because it has no ability to decide. If a door is opening, there must be something else affecting the door such as wind, dogs, installed automatic mechanisms, etc. Even if it's a haunted door, it should be opened by a ghost inside it, not by the door itself. The "door" is passive, not active.)
- This bowl is filling up. ☞ 이 그릇이 채워지고 있다. This bowl is being filled up.
- It feels like I am your teacher. ☞ 내가 마치 네 선생님인 것처럼 느껴진다. [It] is felt like I am your teacher. ("It" is a dummy subject. A dummy subject can't feel something because it is not a living being. "It" must have been felt by someone. English speakers might be used to these expressions, but this kind of nonsense has no place in Korean. It feels, a book sells, a game begins, a door opens, a door closes, it looks, etc.)
- ※ Grammar Breakdown
- 내가 네 선생님 : I your teacher
- 내가 네 선생님이다 : I am your teacher.
- 내가 네 선생님인 : (NOUN) that I am your teacher ("-인" is the attributive form of "-이다" meaning "be, am, are, is". "-이다" and "-인" both are the present tense.)
- 내가 네 선생님인 것 : the thing that I am your teacher
- 내가 네 선생님인 것처럼 : like the thing that I am your teacher
- 내가 네 선생님인 것처럼 느껴진다 : (It) is felt like the thing that I am your teacher. (느껴진다 (is felt) is the present tense)
- 마치 means "as if". You can put 마치 anywhere in the sentence or just omit it. Word order is not that important in Korean in the first place. You can also declare a topic with 나는(난) anywhere in the sentence. English speakers usually place much value on word order and try to focus on word order of Korean, because English is an analytic language in which word order is very important for understanding the meaning. Korean is not an analytic language, so you should change your approaching method. You should focus on how various suffixes are attached at the end of each word to assign their grammatical roles in a sentence, rather than word order. If you are not familiar with the word order of Korean, you can practice in any word order you want. You can refine it later when you are more experienced. Even if you change word order as you want, the Koreans would have no problem understanding your Korean though it might sound a bit unusual or wacky. I am demonstrating this to show word order is actually kind of irrelevant in Korean. Destroy your stereotype given by your native language, and don't be afraid of being different about word order.
- 내가 네 선생님 : I your teacher
- 나는 느껴진다 마치 내가 네 선생님인 것처럼.
- 나는(As for me) 느껴진다(it is felt) 마치(as if) 내가(I) 네(your) 선생님인(teacher am that) 것처럼(the thing like).
- The "-인" in "선생님인" is an attributive form as already explained, which means a noun (in this case, 것) has to be followed. So, the word order "선생님인 것처럼" is fixed and can't be changed. They are kind of integrated by the suffix "-인".
- 나는 느껴진다 마치 내가 네 선생님인 것처럼.
- This is another possible translation.
- 나는(As for me) 내가(I) 느껴진다(am felt) 마치(as if) 네(your) 선생님인(teacher being) 것처럼(the thing like).
Some Korean passive forms should be translated to the active voice in English. (Both the active and passive forms are natural in Korean, but only the active voice is natural in English.)
- 이 현실이 믿기지가 않았다. This reality was not believed (by me). ☞ ([I] couldn't believe this reality.)
- 이 현실을 믿을 수가 없었다. [I] couldn't believe this reality.
Many passive voice English expressions should be translated to the active form in Korean. (Both the active and passive voices are natural in English, but only the active form is natural in Korean.)
- I was interviewed. ☞ 나는 면접을 받았다. (I received an interview.) : ("-을 받다" can be considered a passive form itself. "나는 면접을 봤다" is also possible but this is nowhere near a passive form.)
- I was brought here. 나는 여기에 데려와졌다. (Although it can be literally translated, it sounds unnatural in Korean.) ☞ 그 사람이 나를 여기에 데려왔다. He brought me here.
- I was told that you were my son. (If I have to translate "be told", it would be 말해지다 or 이야기되다 but these expressions are unnatural in Korean) ☞ 네가 내 아들이라고 들었다. ([I] heard that you are my son.)
- ※ Think about this sentence "Give me a book." In this sentence, "a book" is the direct object (accusative case, -을/-를), and "me" is the indirect object (dative case, -에게). If you change word order (Give a book me), it is wrong that's why English is an analytic language and word order is fixed. In English, both of them ("a book" and "me") can be the subject of the passive voice (a book was given to me , I was given a book), but in Korean, only the direct object "a book" can be the subject of the passive verb. In Korean, the indirect object is not even called as "object", it's the dative case that is completely different.
- "I was given" has two possible meanings, it's an ambiguous expression. It can be either "someone gave something to me" or "someone gave me to another person (I am like a human slave that can be gifted)." In Korean, "I was given (내가 주어졌다)" only means the second translation (I am a slave). This kind of grammatical ambiguity doesn't exist in Korean, and it is applied to all other Korean verbs. "I was told" only means "someone told about me to another person" so "I was told (of a story)" doesn't make sense in Korean. It has to be "a story was told (to me)" in the passive voice.
- ※ Grammar Breakdown
- 네가 내 아들 : you my son
- 네가 내 아들이다 : You are my son.
- 네가 내 아들이다라고 : (VERB) that "You are my son"
- 네가 내 아들이라고 : (VERB) that you are my son (if "아들" doesn't have an ending consonant, -이라고 becomes -라고. for example, 친구 + (이)라고 → 친구라고)
- 네가 내 아들이라고 듣다 : to hear that you are my son
- 네가 내 아들이라고 듣는다 : Hear(s) that you are my son.
- 네가 내 아들이라고 듣겠다 : Would hear that you are my son.
- 네가 내 아들이라고 들었다 : Heard that you are my son.
- 네가 내 아들이라고 들었겠다 : Would have heard that you are my son.
- 네가 내 아들이라고 : (VERB) that you are my son
- 네가 내 아들이라고 하다 : to tell that you are my son
- 네가 내 아들이라고 한다 : Tell(s) that you are my son.
- 네가 내 아들이라고 하는 : (NOUN) that tells that you are my son
- 네가 내 아들이라고 하는 이야기 : a story that tells that you are my son
- 네가 내 아들이라고 하는 이야기를 들었다 : Heard a story that tells that you are my son.
- 네가 내 아들이라는 얘기를 들었다 (contracted from the previous sentence, same meaning)
- 네가 내 아들이란 얘길 들었다 (above sentence can be even further contracted, that is similar to the actual colloquial language. See the shrinking process "아들이라고 하는" → "아들이라는" → "아들이란", and "이야기를" → "얘기를" → "얘길". This kind of process happens all the time in Korean, and it is key to understand the actual spoken language.)
- If you want to clarify the subject who heard the story, declare a topic with 나는(난).
- 난 네가 내 아들이란 얘길 들었다 : As for me, (I) heard a story that tells that you are my son. (this final sentence looks simple, but it has a quite complex structure, especially in the "아들이란" part.)
- 네가 내 아들 : you my son
This grammar part should be explained together with the causative form but many Korean materials for foreigners skip it due to its confusing nature. If you are a casual learner and don't want to be stressed out, you can skip it but if you are trying to learn Korean seriously, you must learn it otherwise you'll never understand this part. This grammar part is hard, even for many native Korean speakers, so don't be afraid of making mistakes. I’ll outline the grammar structure with example verbs, you would be able to briefly understand how it works in Korean.
굽다 has two meanings and their conjugational forms are different.
- 굽다1 : to be bent
- 굽어지다 : to (naturally) become bent : (-어지다 is always passive. in this case, 굽다 follows the regular conjugation rule. this "naturally" means "not by someone intentionally")
- 굽게 하다1 (?) : to make something become bent , to bend something : (-게 하다 is always causative. technically, this is correct but hardly used because there is another causative form 굽히다. it seems like the Bible in Korean version uses this 굽게 하다 because it gives a unique unusual nuance.)
- 굽히다 : to make something become bent , to bend something : (this -히 is causative)
- 굽혀지다 : to become bent by someone : (causative -히 + passive -어지다. try to pronounce 굽히어지다 fast then you get 굽혀지다.)
- 굽다2 : to bake
- 굽히다2 (X) : (this is a theoretically expected passive or causative form of 굽다2 but according to the standard Korean dictionary, this is wrong.)
- 구워지다 : to be baked : (-어지다 is always passive. in this case, 굽다 follows the ㅂ irregular conjugation rule. try to pronounce 구우어지다 fast then you get 구워지다.)
- 굽게 하다2 : to make/let someone bake something : (-게 하다 is always causative. since 굽게 하다1 is hardly used, you can assume 굽게 하다 is this thing in most cases)
- ※ The "pronounce fast and get something" rule is applied to all verbs except for the irregular 으 dropping verbs. You can see an irregular example of 잠그다 at the end of this page.
In the example above, -히 is a causative suffix, but it can be a passive suffix either in many other verbs.
- 먹다 : to eat
- 먹어지다 (?) : to be eaten : (-어지다 is always passive. Technically, this is correct but hardly used because there is another passive form 먹히다. You'll probably never see or use this form.)
- 먹히다 : to be eaten : (this -히 is passive)
- 먹혀지다 (X) : to be eaten : (passive -히 + passive -어지다. this is wrong as it is a double passive)
- 먹이다 (먹게 하다) : to make/let someone eat , to feed : (this -이 is causative)
- 먹여지다 : to be fed : (causative -이 + passive -어지다. this is correct but hardly used.)
- ※ To be precise, the exact meanings of 먹어지다 and 먹히다 are slightly different. It's so subtle, very hard to explain in English. Let's say, if you are trying to eat a metal spoon (a metal spoon looks physically impossible to chew and swallow), I would say, 그게 먹어져요? (Can it be eaten?) but I wouldn't say 그게 먹혀요? (Is it eaten?). -어지다 can imply "(physically) possible" in some verbs.
For some verbs, the passive and causative forms are morphologically identical.
- 보다 : to see
- 보아지다 (봐지다) (?) : to be seen : (-아지다 is always passive. technically, this is correct but hardly used because there is another passive form 보이다1. you'll probably never see or use this form.)
- 보이다1 : to be seen : (this -이 is passive)
- 보여지다1 (X) : to be seen : (passive -이 + passive -어지다, this usage is wrong as it is a double passive)
- 보이다2 (보게 하다) : to make/let someone see , to show : (this -이 is causative. to avoid confusion, 보여주다 (보이다2 + -어주다) is used in most cases)
- 보여지다2 : to be shown : (causative -이 + passive -어지다) : (e.g. 마침내 그 끔찍한 진실이 관객들에게 보여졌다: Finally, the horrendous truth was shown to the audience)
- 듣다 : to hear : (this verb follows the ㄷ irregular conjugation rule)
- 들어지다 (?) : to be heard : (-어지다 is always passive. technically, this is correct but hardly used because there is another passive form 들리다1. you'll probably never see or use this form.)
- 들리다1 : to be heard : (this -리 is passive)
- 들려지다1 (X) : to be heard : (passive -리 + passive -어지다, this usage is wrong as it is a double passive)
- 들리다2 (듣게 하다) : to make/let someone hear, to tell(when talking) : (this -리 is causative. to avoid confusion, 들려주다 (들리다2 + -어주다) is used in most cases) : (e.g. 내 노래를 들려줄게 (듣게 해줄게): I'll let you hear my song)
- 들려지다2 : passive form of 들리다2 : (causative -리 + passive -어지다) : (e.g. 너의 노래가 나에게 들려졌다: Your song was told(heard) to me)
- ※ 들리다1 is simply "to be heard" whereas 들려지다2 is like someone is deliberately moving the source of the sound to your ears because he wants you to hear it. Likewise, 보이다1 is simply "to be seen" whereas 보여지다2(to be shown) is like someone is deliberately moving something in front of your eyes because he wants you to see it. If you can notice the difference between "진실이 보였다 (the truth was seen)" and "진실이 보여졌다 (the truth was shown)", you can also know the difference between "너의 노래가 들렸다 (your song was heard)" and "너의 노래가 들려졌다 (your song was VERB)". (I think there is no adequate verb for 들려지다2 in English, so you should imagine it)
- ※ In the Gyeongsang and Hamgyŏng dialects, 듣기다 is used instead of 들리다1. In these dialects, 듣기다(passive) and 들리다(causative) are different. Any dialect is the correct Korean language.
- ※ The passive ending -어지다 changed to -아지다 for 보아지다. If you don't know why it changes, see Vowel harmony.
Many verbs have two possible passive forms but only one of them is preferred in most cases. (the less preferred one might even sound unnatural) For some verbs, however, the two passive forms are equally preferred, either one is fine.
- 믿다 : to believe
- 믿기다 : to be believed : (this -기 is passive)
- 믿어지다 : to be believed : (-어지다 is passive)
- 믿겨지다 (X) : to be believed : (passive -기 + passive -어지다. this is wrong as it is a double passive)
- 믿게 하다 : to make/let someone believe something : (for this verb, only the -게 하다 causative is possible and there is no alternative causative form.)
- 끊다 : to cut
- 끊기다 : to be cut : (this -기 is passive)
- 끊어지다 : to be cut : (-어지다 is passive)
- 끊겨지다 (X) : to be cut : (passive -기 + passive -어지다. this is wrong as it is a double passive)
- 끊게 하다 : to make/let someone cut something : (for this verb, only the -게 하다 causative is possible and there is no alternative causative form)
- ※ 끊다 has another passive-alike form 끊이다. This word is almost always used as negative forms "끊이지 않다 (never be cut/stopped, constantly continuous)" , "끊임(이) 없다 (there is no cutting/stopping, constantly continuous)".
- ※ If you are trying to cut a rope with your bare hands (it looks physically impossible), I would say 그게 끊어져요? (Can it be cut?) but I wouldn't say 그게 끊겨요? (Is it cut?). It's the same thing in 먹어지다 and 먹히다 mentioned above. There is a subtle difference.
There are some verbs that even most native Koreans fail to conjugate correctly.
- 잊다 : to forget
- 잊히다 : to be forgotten : (passive -히)
- 잊어지다 : to be forgotten : (passive -어지다, this form is correct but hardly used)
- 잊혀지다 (X) : to be forgotten : (a double passive using both -히 and -어지다. this is wrong)
- 잊게 하다 : to make/let someone forget something : (for this verb, only the -게 하다 causative is possible and there is no alternative causative form.)
Not to be confused with the normal causative+passive form. (they look like the double passive form but they are different.)
- 숨다 : to hide : (intransitive)
- 숨기다 : to make/let something become hidden, to hide something : (causative -기)
- 숨겨지다 : to become hidden by someone : (causative -기 + passive -어지다)
- 남다 : to remain : (intransitive)
- 남기다 : to make/let something remain, to leave something : (causative -기. not to be confused with 떠나다 meaning "to depart, to leave")
- 남겨지다 : to be left : (causative -기 + passive -어지다)
- 알다 : to know : (this verb follows the ㄹ irregular conjugation rule)
- 알리다 : to make/let someone know, to inform, to notify : (causative -리)
- 알려지다 : to be informed, to become known : (causative -리 + passive -어지다) : (e.g. 닐 암스트롱의 이름이 세상에 알려졌다: Neil Armstrong's name was informed (became known) throughout the world)
Some verbs don't allow the passive suffixes at all. These exceptional verbs need some special passive forms.
- 죽다 : to die
- 죽이다 : to make/let someone die , to kill : (causative -이)
- 죽여지다 (?) : to be killed (?) : (this is the expected passive form of 죽이다, but this is not used.)
- 죽임을 당하다 : to be killed : (causative -이 + nominalization -ㅁ + passive -을 당하다)
- 사망(死亡)하다 : to die : (Sino-Korean equivalent)
- 살해(殺害)하다 : to kill : (Sino-Korean equivalent)
- 살해(殺害)당하다 : to be killed : (Sino-Korean equivalent)
- 살해(殺害)되다 : to be killed : (Sino-Korean equivalent)
- 피살(被殺)되다 : to be killed : (Sino-Korean equivalent)
묻다 has three meanings and each of them has different conjugational forms.
- 묻다1 : to bury
- 묻히다1 : to be buried : (this -히 is passive)
- 묻어지다 : to be buried : (passive -어지다. this form is correct but hardly used)
- 묻혀지다1 (X) : to be buried : (passive -히 + passive -어지다, this usage is wrong as it is a double passive)
- 묻게 하다 : to make/let someone bury something : (causative form in -게 하다)
- 묻다2 : to be smeared
- 묻히다2 : to make/let something become smeared, to smear : (this -히 is causative. note that the previous 묻히다1 is passive)
- 묻혀지다2 : to become smeared with something by someone : (causative -히 + passive -어지다)
- 묻다3 : to ask : (this verb does not have a passive form. theoretically, it should be 물어지다 in the passive form but this is not used. instead, 물음을 받다 would work as the passive form. 물음 is a noun form of 묻다(to ask), as the object suffix -을/-를 is only attached to nouns. however, 물음을 받다 sounds kind of uncommon. the most frequently used passive form for this verb would be 질문(質問)을 받다, the Sino-Korean alternative. this 묻다3 verb follows the ㄷ irregular conjugation rule.)
- 물어보게 하다 : to make/let someone ask something : (causative form in -게 하다. theoretically, it should be 묻게 하다 but this can be misunderstood as the 묻다1 verb.)
Adjectives can also become passive and causative verbs.
- 낮다 : be(is) low (adjective)
- 낮아지다 : to become low : (passive -아지다, verb)
- 낮추다 : to make/let something low , to lower : (this -추 is causative)
- 낮춰지다 : to become lowered by someone : (causative -추 + passive -어지다)
- 높다 : be(is) high (adjective)
- 높아지다 : to become high : (passive -아지다, verb)
- 높이다 : to make/let something high, to raise : (this -이 is causative)
- 높여지다 : to become raised by someone : (causative -이 + passive -어지다)
- ※ To be precise, [adjective + -어/-아지다] can't be called as "passive form" but practically there is no difference in Korean.
Some causative forms in the -우 suffix are inflected with the vowel ㅣ.
- 자다 : to sleep (intransitive)
- 재우다 : to make/let someone sleep : (자 + ㅣ + 우 + 다)
- 재워지다 : passive form of 재우다 : (causative -우 + passive -어지다)
- 차다 : to fill (intransitive. 차다 has many meanings and their conjugational forms are different by each meaning, as in 묻다 explained above.)
- 채우다 : to make something filled, to fill something : (차 + ㅣ + 우 + 다)
- 채워지다 : to be filled : (causative -우 + passive -어지다)
- 서다 : to stand (intransitive)
- 세우다 : to make/let something stand : (서 + ㅣ + 우 + 다)
- 세워지다 : passive form of 세우다 : (causative -우 + passive -어지다)
Some verbs have multiple causative forms.
- 눕다 : to lie (down) : (intransitive)
- 눕게 하다 : to make someone lie (down), to lay someone (down) : (causative -게 하다)
- 눕히다 : to make someone lie (down), to lay someone (down) : (causative -히)
- 눕혀지다 : to be laid (down) : (causative -히 + passive -어지다)
- 누이다 (뉘다) : to make someone lie (down), to lay someone (down) : (눕다 + 이 → 눕이다 → 누우이다 → 누이다 → 뉘다)
- 누여지다 : to be laid (down) : (causative -이 + passive -어지다)
Double causative forms are possible and correct.
- 죽이다 (죽게 하다) : to make someone die, to kill
- 죽이게 하다 : to make someone kill (causative -이 + causative -게 하다) : (e.g. "Hey John, kill Lisa" → I made John to make Lisa die)
- 재우다 (자게 하다) : to make someone sleep
- 재우게 하다 : to make someone1 to make someone2 sleep : (e.g. "Hey Lisa, put me to sleep" → I made Lisa to make me sleep)
The 르 irregular verbs follow a special pattern.
- 구르다 : to roll (intransitive)
- 굴리다 : to make something roll, to roll something (causative)
- 굴려지다 : passive form of 굴리다
- 누르다 : to press
- 눌리다 : to be pressed (passive)
- 눌러지다 : to be pressed (passive -어지다)
- 눌려지다 (X) : to be pressed (double passive, this is wrong)
- ※ 굴리다 and 눌리다 have the same pattern, seemingly they are easy. However, 굴리다 is causative, 눌리다 is passive. There is no specific way to know which one is passive and which one is causative. You have to just memorize them whenever you encounter new words. You have to look up in a dictionary to know if they are passive or causative. If you find this grammar part very confusing, it is normal. I guess you are doing well. Welcome to the most irrational and absurd part of Korean. This part will be the final hurdle on the road to master the grammar of Korean.
When verbs have a -하다 (to do) ending, the conjugations are different from the rules above. Most Hanja words (Chinese loanwords) belong to this part.
When 하다 verbs have a monosyllabic stem, they tend to take the -어/-아지다 ending.
Note that the 하다 verb itself is irregular.
[하다 + -어/-아지다 → 하여지다 → 해지다]
- 칠하다 : to paint
- 칠해지다 (칠하여지다) : to be painted
- 정하다 : to decide
- 정해지다 (정하여지다) : to be decided
Note that there are many exceptions, this is not an established principle. For example, 변하다 (to change, intransitive) already works like a passive form without any conjugation. If you use 변해지다 which is wrong, the Koreans would instantly notice that you are not a native speaker. The native Korean counterpart for "to change", 바꾸다, has a normal passive form 바뀌다. In short,
- 변하다 : (not used as the active form)
- 변하다 : to be changed (passive / intransitive)
- 바꾸다 : to change (active)
- 바뀌다 : to be changed (passive)
바뀌다 and 변하다 are interchangeable because they both work as passive forms. For example,
- My mind was changed = 내 마음이 바뀌었다 = 내 마음이 변했다 : 내 마음(my mind) is the subject of the sentence
바꾸다(active) can't be replaced with 변하다(passive).
- [I] Changed my mind = 내 마음을 바꾸었다(바꿨다) : 내 마음(my mind) is the object of the sentence
- ※ If you want to use the stem 변 as a transitive verb, you must use other correct transitive verbs such as 변경하다, 변화시키다.
When 하다 verbs have a polysyllabic stem, they don't add the -어/-아지다 ending. Instead, the 하다 ending changes to 되다 or 당하다 or 받다. (you should memorize which one to use. most verbs allow one or two ways out of the three)
- 결정하다 : to decide
- 결정되다 : to be decided (Note : 결정하다 is a synonym of 정하다 above, the only difference is the prefix 결, but they follow different rules.)
- 구타하다 : to beat up
- 구타당하다 : to be beaten up (당하다 means "to suffer")
- 지원하다 : to support
- 지원받다 : to be supported (받다 means "to receive")
The causative form of 하다 is 시키다.
- 실행하다 : to carry out
- 실행시키다 : to make someone to carry out something
- 실행하게 하다 : to make someone to carry out something
- ※ Note : Many 하다 verbs don't take the 시키다 causative form. 하게 하다 can be applied universally.
Note that Korean adjectives can have the 하다 ending too, but the 하다 in adjectives is a different thing and doesn't mean "to do". The conjugation rules are also different. They take the -어/-아지다 and -게 되다 forms like verbs but the 시키다 causative form is not used. This poses another difficulty because 하다 verbs and adjectives look the same, so you can't determine if they are verbs or adjectives unless you look up in a dictionary. You should first figure out if they are verbs or adjectives, then you can apply the correct conjugation rule.
- 깨끗하다 : be(is) clean (adjective)
- 깨끗해지다 : to become clean (verb)
- 깨끗하게 되다 : to become clean (verb)
- 깨끗하게 하다 : to make/let something be(is) clean (-게 하다 causative)
- 깨끗해지게 하다 : to make/let something become clean (-게 하다 causative)
- ※ Note : For 하다 adjectives, whether the stem is monosyllabic or polysyllabic doesn't matter. The passive form is always "하다 → 해지다" and "하다 → 하게 되다". (It only matters to 하다 verbs.)
Note that (하)게 하다 and (하)게 되다 are different. (하)게 하다 is a causative form for verbs and adjectives, (하)게 되다 is like "to become" for adjectives. If verbs take (하)게 되다, the meaning is slightly different. It's like "end up doing / get to do".
- 결정하다 : to decide (verb)
- 결정되다 : to be decided (verb)
- 결정하게 하다 : to make/let someone to decide something : (the 시키다 causative form is not used for this verb)
- 결정되게 하다 : to make/let something to be decided : (-게 하다 causative)
- 결정하게 되다 : to end up deciding something , to get to decide something
- 결정되게 되다 : to end up being decided : (same with other non-되다 passive verbs. for example, [정해지게 되다 : to end up being decided] , [구타당하게 되다 : to end up being beaten up] , [먹히게 되다 : to end up being eaten])
- 결정해지다 (X) : (if you don't understand why this is wrong, read the explanation again. hint : 결정하다 is a verb and the stem 결정 is polysyllabic.)
- 익숙하다 : be(is) accustomed (adjective)
- 익숙하게 되다 : to become accustomed (verb)
- 익숙해지다 : to become accustomed (verb)
- 익숙해지게 하다 : to make/let someone to become accustomed (verb) : (-게 하다 causative)
- 익숙되다, 익숙당하다, 익숙받다 (X) : (if you don't understand why this is wrong, read the explanation again. hint : 익숙하다 is an adjective.)
In short, the conjugations for the passive and causative forms vary with individual verbs, but there are some patterns. (most passive verbs take one of -이, -히, -리, -기 or -어/-아지다 or -되다/-당하다/-받다. most causative verbs take one of -이, -히, -리, -기, -우 ,-구, -추 or -시키다 or -게 하다). The four suffixes -이, -히, -리, -기 are particularly tricky as they could be either passive or causative (or sometimes both). If you come across a Korean word you don't know, suffixed with one of the four suffixes, you can't really determine whether it is passive or causative unless you look up in a Korean dictionary, because the meaning of those four suffixes in individual verbs is arbitrary. (Say, if you come across an English word you don't know, suffixed with "-ed" ending, you can soon figure out that it is a past tense suffix for a verb, but you can't determine the function of the four Korean suffixes without a Korean dictionary) Besides, when they have the -하다 ending, you have to figure out if they are verbs or adjectives, because verbs and adjectives follow different rules despite looking exactly the same things. That's why most Korean materials for foreigners overlook or skip this grammar part. They (those who created Korean materials for foreigners) often say "Passive form is not much used in Korean" or "Passive form is not as common as it is in English". The first argument is wrong. Passive form is very common in Korean in fact. The latter argument might be true in many cases but dubious if it's concluded from any valid statistics. As previously shown, many active voice English expressions should be translated to the passive form in Korean, but it is often ignored. It seems like many Koreans aren't even aware that they are actually speaking in the passive form. I have never seen someone explain 믿기지 않다 or 믿어지지 않다 or 믿겨지지 않다 as the passive form. Most people just explain it as "can't believe". That's how you end up thinking the passive form is not common in Korean without understanding the underlying grammar structure. Depending on the situation, the passive form in Korean could be even more common than the passive voice in English.
There is another problem. The Korean-English dictionary is designed for Korean people trying to learn English, not for foreign people trying to learn Korean. 맺히다 is a passive form of 맺다 but if you find this word in the Korean-English dictionary, there is no such information and the definition doesn't even look like a passive voice, because English speakers seldom use the passive voice for this verb. If you find 팔리다 in the dictionary, the definition is either "sell" or "be sold" so English speakers may misunderstand 팔리다 has both meanings, but it is in fact the English word "sell" that has both meanings 팔다(to sell) and 팔리다(to be sold). I have already explained about 팔리다 at the beginning of this page. 열다 and 열리다 are even the same meaning "open" according to the dictionary. Therefore, you should find these words in the Korean-Korean dictionary. 피동사 means passive verb, 사동사 means causative verb so you can finally be 100% sure about them.
This grammar part is very confusing even for native Korean speakers. Many Koreans are still using double passive words like 잊혀지다, because they are not sure about the function of the -히 suffix. It feels like 잊히다 is not sufficient to represent a passive form, because -히 works as causative in many other verbs (as in 굽히다 and 묻히다2 above), so they just added the passive ending -어/-아지다 again to make sure that it is a passive form. (Try to imagine a word like "forgottened" which has an extra "-ed" suffix. That's what's called the double passive in Korean. Now think about the word "enlightened". The "-ened" suffix in "enlightened" is working like causative(-en) + passive(-ed), whereas the "-ened" suffix in "forgottened" is just a double passive. Now imagine there are tons of these things in English. It would be very confusing and at some point, you won't be sure if "forgottened" is correct or wrong, because there are many similar looking but correct words like "enlightened". It's exactly what is happening in Korean.) I think they (those who created Korean materials for foreigners) are just avoiding some nettlesome parts. Who would want to freak out their customers? In practice, each form of every verb should be memorized.
※ Further explanation about the passive form and the attributive form with tense.
In English, somehow the past participles are used for the passive voice, so English speakers naturally relate the completely different two concepts. In Korean, however, the past tense has nothing to do with the passive form. They are morphologically completely different. Besides, English verbs don't have any attributive conjugational forms. The verb conjugations are much simpler in English so it is causing misunderstandings or difficulties of Korean to English speakers. Think about this phrase "a pretty girl". English speakers never say "a pretty-ed girl" or "a pretty-will girl" so it is basically impossible to naturally convey connotations of Korean. I hope the following over specific translations can convey this Korean part.
A passive verb, for example, 먹히다 (to be eaten) is the infinitive form (the basic verb form used in the dictionary), it doesn't even have any tense (it is not the present tense. it literally has no tense whatsoever), so you should conjugate it in actual Korean. Let's make it to the attributive past tense.
- 먹힌 닭 : a chicken that was eaten , a chicken that has been eaten (an eaten chicken) : (in Korean, the past and the present perfect tenses are kind of merged. in most cases, the present perfect can be just replaced with the past tense. in this page, probably it would be the only thing that is definitely simpler in Korean than it is in English.)
먹힌 alone implies three additional connotations along with the basic meaning "to eat". -히 stands for the passive form, -ㄴ/은 stands for the past tense and the attributive form combined. If the verb stem has an ending conosonant (e.g., 먹 in 먹다), -은 is used instead (먹다→먹은 as opposed to 먹히다→먹힌). Let's change it to the present tense.
- 먹히는 닭 : a chicken that is eaten (a chicken that is being eaten. similar to 먹히고 있는 닭)
-히 stands for the passive form, -는 stands for the present tense and the attributive form combined. It looks exactly like 먹히 is a noun and -는 is the topic marker. It may be greatly confusing for beginners. It is what learners have to overcome. Let's change it to the future tense.
- 먹힐 닭 : a chicken that will be eaten , a chicken that is going to be eaten (English doesn't have a grammatical future tense but Korean does.)
-히 stands for the passive form, -ㄹ/을 stands for the future tense and the attributive form combined. Let's change to the past-future tense.
- 먹혔을 닭 : a chicken that would have been eaten (먹 + 히 + 었 + 을 → 먹혔을)
-히 stands for the passive form, -었 stands for the past tense, -을 stands for the future tense and the attributive form combined. See more variations.
- 먹히던 닭 : a chicken that was being eaten (-던 implies the speaker is thinking about the past retrospectively)
- 먹혔던 닭 : a chicken that was eaten before (similar to 먹힌 닭, retrospectively)
- 먹혔었던 닭 : a chicken that had been eaten before (similar to 먹힌 닭 and 먹혔던 닭, retrospectively)
- 먹히고 있는 닭 : a chicken that is being eaten (similar to 먹히는 닭 but emphasizing the action is being done now)
- 먹히고 있던 닭 : a chicken that was being eaten
- 먹히고 있었던 닭 : a chicken that was being eaten
- 먹히고 있을 닭 : a chicken that will be being eaten
- 먹히고 있었을 닭 : a chicken that would have been being eaten (this one is hard to translate. you should change the "have been" part to "was". imagine "would" and "was being eaten" are combined)
- 먹히게 되는 닭 : a chicken that ends up being eaten (I've already explained about the -게 되다 grammar)
- 먹히게 될 닭 : a chicken that will end up being eaten
- 먹히게 된 닭 : a chicken that (just) ended up being eaten
- 먹히게 되었던 닭 : a chicken that (had) ended up being eaten
- 먹히게 되었었던 닭 : a chicken that had ended up being eaten
- 먹히게 되었을 닭 : a chicken that would have ended up being eaten
Be careful it is slightly different for adjectives.
- 예쁘다 : to be pretty (adjective)
- 예쁜 닭 : a chicken that is pretty (a pretty chicken) : (unlike verbs, -ㄴ/은 stands for the present tense. it may be confusing)
- 예뻤던 닭 : a chicken that was pretty : (this alternative past tense form is applied to adjectives, which is same with that of verbs)
- 예쁘던 닭 : a chicken that was pretty : (implies the chicken used to be pretty, retrospectively)
- 예뻤었던 닭 : a chicken that was pretty before (a chicken that had been pretty before)
- 예쁘는 닭 (X) : (if 예쁘다 was a verb, -는 stands for the present tense, but it is an adjective so -는 is completely wrong)
- 예쁠 닭 : a chicken that will be pretty : (the future tense follows the same pattern for verbs. in this case 예뻐질 닭 (a chicken that will become pretty) would be more natural.)
In short, -ㄴ/은 is the past tense for verbs, but present tense for adjectives. -는 is the present tense for verbs, but wrong for adjectives.
I have said that Korean verbs must be conjugated in a sentence, but there is a trap that makes a conjugated verb look like an ordinary infinitive form. Take a look at this sentence.
- 먹히다 간신히 탈출했다.
In this sentence, 먹히다 looks exactly like the basic infinitive form, but it isn't in fact. That 먹히다 is contracted from 먹히다가 (먹히다 + -다가) meaning "while being eaten"
- 먹히다가 간신히 탈출했다. : (Someone) Barely escaped while being eaten. (He was being eaten alive, but barely escaped.)
If you ever come across a verb in a sentence that looks like an unconjugated form, it is the -다가(while) form. It is just contracted to -다(while).
Korean has two different suffixes for the meaning "while". In fact, "-(으)면서" is more similar to the meaning of the English "while". Google if you want to know about the difference between -다가 and -(으)면서.
There is another case. In headlines or titles of some articles, the unconjugated verb form can be used.
- 관광객, 상어에게 잡아먹히다! : A tourist, eaten by a shark! (this is supposed to be a headline of a news)
In this case, that 먹히다 is the unconjugated form. So, this headline has no tense. (먹힌다 for present tense, 먹혔다 for past tense)
※ -이다 vs -하다
Let's assume your parents gave you a name as "Lovely" when you were born. How would you introduce yourself when you meet someone?
- Hello, I am Lovely. (sounds so narcissistic)
- Hello, my name is Lovely. (sounds like boasting of her name)
It is a very awkward situation, isn't it? If you remember this specific situation, you will never be confused about -이다 and -하다. The fundamental problem is that you can't specify the grammatical role of "lovely". Your name is supposed to be a noun but it sounds like an adjective due to the same pronunciation. Languages around the world have various solutions to avoid this kind of problem. English has solved this kind of problem with extensive use of articles. If you put an article like a/an/the, you can make clear that "Lovely" is a noun. However, In this specific situation, unfortunately you can't put any article. I wanted to show what happens when you can't use articles in English. Now you would understand why English speakers are obsessed with correct use of grammatical articles.
Korean has a different solution without using articles.
- 안녕, 나는 Lovely야. (Hello, I am Lovely.) : (-야 explicitly indicates that "Lovely" is a noun. -야 is conjugated from -이다. -입니다, -예요/-이에요 are also possible)
- 안녕, 나는 lovely해. (Hello, I am lovely.) : (-해 explicitly indicates that "lovely" is an adjective. -해 is conjugated from -하다. -합니다, -해요 are also possible)
As you see, the grammar has eliminated the ambiguity, so there is no such an awkward situation in Korean. Instead, there is another problem in Korean. I've already said that there are two different kinds of 하다s in Korean; 하다 for verbs and 하다 for adjectives. Here they go again. In the example above, -해 could be either a verb or an adjective. In the casual speech styles, the grammar is simplified, and the same spelling is used for both of them. Let's make it more clear by using a different speech style.
- 안녕, 나는 Lovely이다. (Hello, I am Lovely.) : ("Lovely" is a noun. -이다 can be shortened to -다 when the noun doesn't have an ending consonant.)
- 안녕, 나는 lovely하다. (Hello, I am lovely.) : ("lovely" is an adjective)
- 안녕, 나는 Lovely한다. (Hello, I do the thing "Lovely".) : ("Lovely" can be anything you can do. for example, it could be a name of a video game.)
All the examples are the present tense. (-이다 the copula for nouns, and adjectives, don't add -ㄴ/는 for the present tense in this speech style. Only verbs do.)
