Lenguia | TOPIK 4 Grammar: 60 Topics & Examples

VERB / ADJ stem + -(으)ㅁ turns the predicate into a NOUN, typically used in FORMAL / WRITTEN Korean: 행복함 ('happiness'), 좋음 ('being good'), 옴 ('coming'). Distinct from -기 (which is conversational and process-focused). -(으)ㅁ is treated as a CONCRETE noun.

Key rule

VERB / ADJ stem + -ㅁ (vowel/ㄹ) / -음 (consonant) = FORMAL NOMINAL. ㄹ KEEPS (만들다 → 만듦). PAST -았/었음. Lexicalized nouns: 삶, 죽음, 꿈, 잠, 슬픔, 기쁨. Contrast with -기 (process, conversational).

Examples

환경 보호의 중요함을 강조했습니다.
케이크를 만듬.
Formal nominalization 중요하다 → 중요함. Translation: (I) emphasized the importance of environmental protection. Romanization: Hwangyeong boho-ui jungyoham-eul ganghohaesseumnida.
한국어 학습의 어려움이 큽니다.
한국어 잘하기 가능합니다.
어렵다 → 어려움 (ㅂ-irregular adjusted). Translation: The difficulty of Korean learning is great. Romanization: Hangugeo hakseub-ui eoryeoum-i keumnida.
삶은 짧지만 의미가 있습니다.
그가 옴을 알아요.
Lexicalized 살다 → 삶 ('life'). Translation: Life is short but meaningful. Romanization: Salm-eun jjalbjiman uimi-ga isseumnida.

Common mistakes

wrong_l_handling
케이크를 만듬.
케이크를 만듦.
ㄹ-stems KEEP ㄹ + -ㅁ → 만듦 (not 만듬). Double-batchim ㄻ.
nominalizer_for_ability
한국어 잘하기 가능합니다.
한국어를 잘할 수 있습니다. / 한국어 잘하기가 가능합니다.
For ABILITY use -(으)ㄹ 수 있다, not bare -기 or -(으)ㅁ.

TOPIK 4 / B2Verb usage

-는 것이다 / -(으)ㄴ 것이다 (emphatic assertion / reformulation)

-는 것이다 / -(으)ㄴ 것이다

STEM + MODIFIER + 것이다 ('the case is that ~') reformulates and EMPHASIZES a previously stated or implied point: 그래서 시험에 떨어진 것이다 ('That's why he failed the exam'). Adds 'the fact / case / matter is ~' framing. Found in writing, explanations, lectures.

Key rule

MODIFIER + 것이다 = emphatic reformulation 'the case is that ~ / the truth is ~'. -는 것이다 (verb present), -(으)ㄴ 것이다 (verb past / adj), -인 것이다 (이다). Distinct from -(으)ㄹ 것이다 future. Used for explanation / restatement in formal writing.

Examples

그래서 시험에 떨어진 것이다.
그래서 시험에 떨어질 것이다. (intended: 'that's why he failed')
Past + emphatic explanation. Translation: That's why (he) failed the exam. Romanization: Geuraeseo siheom-e tteoreojin geosida.
즉, 한국어가 어려운 것이다.
그분이 한국 사람것이다.
Adjective + reformulation. Translation: That is, Korean is (indeed) hard. Romanization: Jeuk, hangugeo-ga eoryeoun geosida.

TOPIK 4 / C1Verb usage

Full quotative paradigm — tense shifts, embedding, layered indirect speech

간접인용 종합

Master-level command of indirect speech: ALL sentence types × ALL tenses × matrix-verb selection × multi-layer embedding × honorific interactions. Builds on T2/T3 basics, adding subtleties like inner-clause tense preservation, layered '~said that ~ said that', and choice between full / contracted forms.

Key rule

Full quotative paradigm: match SENTENCE TYPE (-ㄴ/는다고 / -(이)라고 / -자고 / -(으)라고 / -냐고). Tense preserved INSIDE clause. Layer with double matrix verbs. -아/어 달라고 (speaker) vs -아/어 주라고 (third party). Honorific subject → -(으)시- on matrix.

Examples

민수가 어제 비가 많이 왔다고 말했어요.
민수가 어제 비가 온다고 했어요. (intended: 'rained yesterday')
Past inner clause. Translation: Minsu said it rained a lot yesterday. Romanization: Minsu-ga eoje bi-ga mani watdago marhaesseoyo.
선생님께서 내일 시험을 본다고 하셨어요.
친구가 저한테 동생을 도와 달라고 했어요. (intended: 'asked me to help HIS sibling')
Honorific subject + present statement. Translation: The teacher said we have a test tomorrow. Romanization: Seonsaengnim-kkeseo naeil siheom-eul bondago hasyeosseoyo.
친구가 한국에 갈 거라고 약속했어요.
엄마가 가지 마라고 했어요.
Future + 약속하다. Translation: My friend promised to go to Korea. Romanization: Chingu-ga hangug-e gal georago yaksokhaesseoyo.

Common mistakes

missing_inner_past
민수가 어제 비가 온다고 했어요. (intended: 'rained yesterday')
민수가 어제 비가 왔다고 했어요.
Past inner clause: -았/었다고. Don't strip the past marker — Korean doesn't backshift like English.
dalrago_vs_jurago
친구가 저한테 동생을 도와 달라고 했어요. (intended: 'asked me to help HIS sibling')
친구가 저한테 동생을 도와 주라고 했어요.
-아/어 달라고 = for SPEAKER. For THIRD PARTY benefit, use -아/어 주라고.

TOPIK 4 / B2Verb usage

-(으)려고 하다 vs -(으)ㄹ까 하다 (different shades of intention)

-(으)려고 하다 vs -(으)ㄹ까 하다

Both express future plans, but with DIFFERENT firmness levels: -(으)려고 하다 = COMMITTED intention ('I plan to / intend to'). -(으)ㄹ까 하다 = TENTATIVE / WAVERING consideration ('I'm thinking of / I might'). 갈까 해요 implies the decision isn't firm yet.

Key rule

-(으)려고 하다 = COMMITTED intention. -(으)ㄹ까 하다 = TENTATIVE consideration. -(으)려고 takes 으 with consonants; -(으)ㄹ까 attaches future-modifier -ㄹ/-을. Past matrix → unrealized intention (가려고 했는데 / 갈까 했는데).

Examples

내년에 한국에 가려고 해요.
한국에 갈려고 해요.
Committed. Translation: I plan to go to Korea next year. Romanization: Naenyeon-e hangug-e garyeogo haeyo.
내년에 한국에 갈까 해요.
내년에 한국에 갈까 해요? (as question)
Tentative. Translation: I'm thinking of going to Korea next year. Romanization: Naenyeon-e hangug-e galkka haeyo.
이번 주말에 영화 보려고 해요.
한국 음식을 만들까 해요. (intended 'I'll definitely make')
Committed. Translation: I plan to watch a movie this weekend. Romanization: Ibeon jumare yeonghwa boryeogo haeyo.

Common mistakes

wrong_stem_form
한국에 갈려고 해요.
한국에 가려고 해요.
가다 is vowel stem → 가려고 (NOT 갈려고; that'd be 갈 + 려고 which is wrong).
form_used_as_question
내년에 한국에 갈까 해요? (as question)
내년에 한국에 갈까 해요. (statement) / 내년에 한국에 갈 거예요? (question)
-(으)ㄹ까 해요 is a hedged STATEMENT, not a real question. To ASK someone use -(으)ㄹ 거예요?.

TOPIK 4 / B2Verb usage

-(으)려던 참이다 / -(으)ㄹ 참이다 (just about to / on the verge of)

-(으)려던 참이다 / -(으)ㄹ 참이다

Both express IMMINENCE — 'just about to / on the verge of doing X'. -(으)려던 참이다 = was about to do X right when something happened (often paired with a discovery). -(으)ㄹ 참이다 = on the verge / planning to do X any moment now.

Key rule

-(으)려던 참이다 = was just about to (when ~), past-leaning. -(으)ㄹ 참이다 = about to (now), present moment. Pair with 막 / 마침 for emphasis. 참 = bound noun 'moment'. Built from -(으)려고 + -던 + 참.

Examples

막 나가려던 참에 친구가 왔어요.
막 나가려던 참에요.
Past imminence + interruption. Translation: I was just about to leave when my friend came. Romanization: Mak nagaryeodeon cham-e chingu-ga wasseoyo.
지금 막 나갈 참이에요.
나가려던 참인데 마침 친구가 왔어요. (intended past)
Present moment. Translation: I'm just about to leave now. Romanization: Jigeum mak nagal cham-iyeyo.
전화하려던 참인데 마침 전화가 왔어요.
지금 막 나갈려던 참이에요.
마침 serendipity. Translation: I was about to call and a call came right then. Romanization: Jeonhwaharyeodeon cham-inde machim jeonhwa-ga wasseoyo.

Common mistakes

missing_ida
막 나가려던 참에요.
막 나가려던 참이에요.
참 + 이다 → 참이에요. Don't drop 이.
tense_choice
나가려던 참인데 마침 친구가 왔어요. (intended past)
나가려던 참에 친구가 왔어요. / 나가려던 참이었는데 친구가 왔어요.
For PAST event, use 참에 (when) or past 참이었는데.

TOPIK 4 / B2Verb usage

-아/어 가다 / -아/어 오다 (continuative direction in time — progression)

-아/어 가다 / -아/어 오다

STEM + -아/어 가다 / -아/어 오다 expresses ongoing progress with DIRECTION through time: -아/어 가다 = '~ going / progressing AWAY from now into the future'. -아/어 오다 = '~ coming / having progressed UP TO now from past'. 점점 추워져 가요 ('It's getting colder'). 한국어를 5년 동안 공부해 왔어요 ('I've been studying Korean for 5 years').

Key rule

STEM + -아/어 가다 = ongoing progression INTO FUTURE (gradually). STEM + -아/어 오다 = has been PROGRESSING UP TO NOW (continuative perfect). 가다 = forward / away. 오다 = up to / accumulated. Often paired with 점점 / 계속 / 동안 / 지금까지.

Examples

날씨가 점점 추워져 가요.
한국어를 5년 동안 공부해 가요. (intended: 'have been studying')
Forward progression. Translation: The weather is gradually getting colder. Romanization: Nalssi-ga jeomjeom chuwojyeo gayo.
한국어를 5년 동안 공부해 왔어요.
날씨가 점점 추워져 와요. (intended: getting colder NOW)
Past → now accumulated. Translation: I've been studying Korean for 5 years. Romanization: Hangugeo-reul oyeon dongan gongbuhae wasseoyo.
한국어가 점점 좋아져 가요.
한국어가 좋아져 가다.
Progressive improvement. Translation: My Korean is getting better. Romanization: Hangugeo-ga jeomjeom joajyeo gayo.

Common mistakes

wrong_direction
한국어를 5년 동안 공부해 가요. (intended: 'have been studying')
한국어를 5년 동안 공부해 왔어요.
For PAST → NOW accumulation use -아/어 오다 (와요/왔어요). -아/어 가다 = forward into future.
wrong_direction
날씨가 점점 추워져 와요. (intended: getting colder NOW)
날씨가 점점 추워져 가요.
Forward progression = -아/어 가다. -아/어 오다 implies accumulation FROM past.

TOPIK 4 / B2Verb usage

-지(를) 못하다 / -지(를) 않다 (object marking in long negation)

-지(를) 못하다 / -지(가) 않다

In LONG NEGATION (-지 못하다 / -지 않다), an optional 을/를 or 이/가 can attach to -지 for EMPHASIS or FOCUS. 가지를 못해요 (vs 가지 못해요) emphasizes 'go' specifically. 좋지가 않아요 (vs 좋지 않아요) emphasizes the negation.

Key rule

Long negation -지 못하다 / -지 않다 can take optional 을/를 (action-focus) or 이/가 (state-focus) on the -지: 가지를 못해요 / 좋지가 않아요 = emphatic. SHORT negation (안/못) doesn't allow this. Past, honorific, etc. compose normally.

Examples

한국어를 잘하지를 못해요.
한국어를 안 잘하지를 못해요.
-지를 못하다 emphatic. Translation: I really can't speak Korean well. Romanization: Hangugeo-reul jalhaji-reul mot haeyo.
이 음식이 맛있지가 않아요.
한국어가 안 쉽지가 않아요.
-지가 않다 emphatic. Translation: This food really isn't tasty. Romanization: I eumsig-i masitji-ga anayo.
그 책을 읽지를 않아요.
안 가지를 못해요.
-지를 않다. Translation: I really don't read that book. Romanization: Geu chaeg-eul ilkji-reul anayo.

Common mistakes

double_negation
한국어를 안 잘하지를 못해요.
한국어를 잘하지 못해요. / 한국어를 잘하지를 못해요.
Don't double-negate. 안 + -지 못하다 is redundant.
double_negation
한국어가 안 쉽지가 않아요.
한국어가 쉽지 않아요. / 한국어가 쉽지가 않아요.
Same — don't double-negate with 안 + -지 않다.

TOPIK 4 / B2Verb usage

-(으)ㄹ 줄 몰랐다 (didn't expect / thought otherwise)

-(으)ㄹ 줄 몰랐다 (예상)

STEM + -(으)ㄹ 줄 몰랐다 means '(I) didn't expect that ~ / I thought it wouldn't ~'. 비가 올 줄 몰랐어요 ('I didn't expect it to rain'). Built on -(으)ㄹ 줄 알다/모르다 ('know how to / be aware') — extended to UNEXPECTED OUTCOMES.

Key rule

Vowel/ㄹ + -ㄹ 줄 몰랐다; consonant + -을 줄 몰랐다 = 'didn't expect that ~'. Opposite: -(으)ㄹ 줄 알았다 ('I thought ~'). Distinct from ability -(으)ㄹ 줄 알다/모르다 (T2). For past awareness use -(으)ㄴ 줄 몰랐다 ('didn't realize').

Examples

비가 올 줄 몰랐어요.
비가 오는 줄 몰랐어요. (intended: didn't expect to rain)
Unrealized expectation. Translation: I didn't expect it to rain. Romanization: Bi-ga ol jul mollasseoyo.
이렇게 어려울 줄 몰랐어요.
비가 왔을 줄 몰랐어요.
ㅂ-irreg + 줄 몰랐다. Translation: I didn't think it'd be this hard. Romanization: Ireohge eoryeoul jul mollasseoyo.

그분이 한국 사람을 줄 몰랐어요.
Noun + 일 줄 몰랐다. Translation: I didn't realize he was Korean. Romanization: Geu-bun-i hanguk saram-il jul mollasseoyo.

Common mistakes

wrong_modifier
비가 오는 줄 몰랐어요. (intended: didn't expect to rain)
비가 올 줄 몰랐어요.
Future / unrealized expectation needs -(으)ㄹ. -는 is present-modifier (different meaning).
wrong_perfect_form
비가 왔을 줄 몰랐어요.
비가 온 줄 몰랐어요.
Past awareness uses -(으)ㄴ 줄 몰랐다 (NOT past-modifier inside future).

TOPIK 4 / B1Verb usage

Three purpose constructions compared: -기 위해 vs -(으)러 vs -(으)려고

-기 위해 / -(으)러 / -(으)려고 비교

All three express purpose but differ: -기 위해 = formal 'in order to' (general); -(으)러 = purpose attached to MOTION verbs (가다/오다 only); -(으)려고 = first-person intention 'in order to' (often with planning). 한국어를 배우러 가요 (motion) vs 한국어를 배우려고 노력해요 (intention) vs 한국어를 배우기 위해 책을 샀어요 (formal purpose).

Key rule

-(으)러 = motion-only purpose (가다/오다). -(으)려고 = intention with any verb. -기 위해 = formal purpose with any verb. Match form to context: motion verb → -(으)러; personal intention → -(으)려고; formal / written purpose → -기 위해.

Examples

한국어를 배우러 학교에 가요.
한국어를 배우러 매일 노력해요.
Motion: -(으)러. Translation: I go to school to learn Korean. Romanization: Hangugeo-reul baeureo hakgyo-e gayo.

한국어를 배우으러 학교에 가요.
Intention: -(으)려고 with non-motion. Translation: I try hard every day in order to learn Korean. Romanization: Hangugeo-reul baeuryeogo maeil noryeokhaeyo.

한국어를 배울러 학교에 가요.
Formal: -기 위해. Translation: We must strive to protect the environment. Romanization: Hwangyeong-eul bohohagi wihae noryeokhaeya hamnida.

Common mistakes

le_with_non_motion
한국어를 배우러 매일 노력해요.
한국어를 배우려고 매일 노력해요. / 한국어를 배우기 위해 매일 노력해요.
-(으)러 only works with MOTION verbs in main clause. 노력하다 isn't motion.
wrong_eu_insertion
한국어를 배우으러 학교에 가요.
한국어를 배우러 학교에 가요.
Vowel-stem + -러 (no 으): 배우다 → 배우러.

TOPIK 4 / B1Verb usage

-(으)ㄹ 만하다 (worth doing / bearable / decent)

-(으)ㄹ 만하다

STEM + -(으)ㄹ 만하다 means 'worth doing / decent / acceptable / bearable'. 이 영화는 볼 만해요 ('This movie is worth watching'). 이 음식은 먹을 만해요 ('This food is decent / passable'). Implies modest endorsement, often with reservation.

Key rule

Vowel/ㄹ + -ㄹ 만하다; consonant + -을 만하다 = 'worth ~ing / bearable / decent'. Modifier: -(으)ㄹ 만한 + NOUN. Modest endorsement / reservation. Negative: -(으)ㄹ 만하지 않다.

Examples

이 영화는 볼 만해요.
이 영화는 보 만해요.
Modest recommendation. Translation: This movie is worth watching. Romanization: I yeonghwa-neun bol manhaeyo.

wrong_modifier
이 음식은 먹는 만해요.
이 음식은 먹을 만해요.
-(으)ㄹ 만하다, not -는 만하다.

TOPIK 4 / B2Verb usage

-(으)ㄹ 정도이다 / -(으)ㄹ 만큼 (to the extent that)

-(으)ㄹ 정도이다 / -(으)ㄹ 만큼

Both express EXTENT / DEGREE 'to the point of ~'. -(으)ㄹ 정도이다 = predicative ('it's to the extent that ~'). -(으)ㄹ 만큼 = connective ('as much as / to the extent that ~'). 죽을 정도예요 ('I'm dead tired'). 너무 매워서 못 먹을 만큼이에요 ('It's so spicy I can't eat it').

Key rule

Vowel/ㄹ + -ㄹ; consonant + -을 + 정도이다 (predicative) / 만큼 (connective). 정도 = 'degree'; 만큼 = 'extent / amount'. Adverbial: -(으)ㄹ 정도로. Modifier: -(으)ㄹ 정도의 N. N + 만큼 = 'as much as N'.

Examples

피곤해서 죽을 정도예요.

TOPIK 4 / B2Verb usage

-다(가) 보면 / -다(가) 보니까 (in the process of ~ing)

-다(가) 보면 / -다(가) 보니까

Both describe a PROCESS leading to a result: -다(가) 보면 = 'if you keep ~ing, then ~' (hypothetical future result). -다(가) 보니까 = '(now that) I've been ~ing, ~' (realized past result / discovery). 한국에 살다 보면 한국어가 늘어요 ('If you keep living in Korea, your Korean improves'). 살다 보니까 한국어가 늘었어요 ('Living here, my Korean improved').

Key rule

STEM + -다(가) 보면 = hypothetical future result of continued action ('if you keep ~ing, ~'). STEM + -다(가) 보니까 = realized result of past extended action ('having ~ed, I found ~'). Same subject. Built from -다(가) + 보다.

Examples

한국에 살다 보면 한국어가 늘어요.
한국에 살면 보면 한국어가 늘어요.

TOPIK 4 / B2Verb usage

Decision verbs compared (-기로 하다 / -(으)려고 하다 / -(으)ㄹ까 하다 / -(으)ㄹ래)

결정·의도 표현 비교

Four ways to express decisions / intentions with different firmness, audience-awareness, and tone: -기로 하다 (DECIDED), -(으)려고 하다 (INTEND), -(으)ㄹ까 하다 (CONSIDERING), -(으)ㄹ래 (CASUAL WILL / asking preference). Choose by what you want to convey.

Key rule

-기로 하다 (decided/committed) > -(으)려고 하다 (intend/plan) > -(으)ㄹ까 하다 (considering) > -(으)ㄹ래(요) (casual will / preference). Pick by firmness and audience-awareness. -(으)ㄹ래? = asking listener's preference. -기로 했어요 = finalized decision.

Examples

third_person_with_ulrae
친구가 한국에 갈래요. (intended: friend's plan)
친구가 한국에 갈 거예요. / 친구가 한국에 가기로 했대요.
-(으)ㄹ래요 is typically first-person. For third-person plans use -(으)ㄹ 거예요 or hearsay.

TOPIK 4 / B2Verb usage

-아/어야 하는데 / -아/어야 할 텐데 (should but / hope will)

-아/어야 하는데 / -아/어야 할 텐데

Modal advice expressions: -아/어야 하는데 = 'should ~ but (often unable / regret)'. -아/어야 할 텐데 = 'I hope (someone) will need to / should ~'. Both express necessity with concern. 일찍 자야 하는데 잠이 안 와요 ('I should sleep early but can't sleep'). 친구가 잘해야 할 텐데요 ('I hope my friend does well').

Key rule

STEM + -아/어야 하는데 = 'should ~ but ~' (necessity + obstacle / regret). STEM + -아/어야 할 텐데 = 'I hope ~ will need to / should' (hope for future necessity). PAST -아/어야 했는데 / -아/어야 했을 텐데.

Examples

일찍 자야 하는데 잠이 안 와요.
일찍 자야 한데 잠이 안 와요.
Necessity + obstacle. Translation: I should sleep early but can't fall asleep. Romanization: Iljjik jaya haneunde jam-i an wayo.

친구가 잘 해야 할 텐데요.
Need -(으)ㄹ before 텐데. 해야 + 할 + 텐데.

TOPIK 4 / B2Verb usage

-(으)ㄹ 텐데 advanced (background concern, hospitality, complex hedging)

-(으)ㄹ 텐데 (응용)

T3 introduced basic -(으)ㄹ 텐데 (expectation + concern). T4 adds advanced uses: HOSPITALITY ('you must be tired — please rest'), MULTI-LAYERED concern ('I would think ~ would be ~ but ~'), and EVENT-FORECAST with -았/었을 텐데 (past counterfactual). Sentence-final -(으)ㄹ 텐데(요)... is a polite trailing form.

Key rule

-(으)ㄹ 텐데 = expectation + concern / contrast (T3). Advanced uses: HOSPITALITY (피곤하실 텐데), MULTI-LAYERED concern (모르실 텐데 설명해 드릴게요), PAST COUNTERFACTUAL -았/었을 텐데 ('would have ~'), TRAILING -(으)ㄹ 텐데(요)... (open-ended concern).

Examples

피곤하실 텐데 좀 쉬세요.
피곤할 텐데 쉬세요. (to a respected listener)
Hospitality. Translation: You must be tired — please rest. Romanization: Pigonhasil tende jom swiseyo.

Common mistakes

missing_honorific
피곤할 텐데 쉬세요. (to a respected listener)
피곤하실 텐데 쉬세요.
Add honorific -(으)시- when addressing a respected listener: 피곤하 + 시 + -ㄹ 텐데 = 피곤하실 텐데.
spacing
갔으면 만났을텐데.
갔으면 만났을 텐데.
Space before 텐데. 만났을 텐데 is two units.

TOPIK 4 / B2Verb usage

-(으)ㄹ 걸 (그랬다) (should have / I wish I had)

-(으)ㄹ 걸 (그랬다)

STEM + -(으)ㄹ 걸 (그랬다) expresses REGRET — 'I should have ~ed / I wish I had ~ed'. 일찍 잘 걸 그랬어요 ('I should have slept early'). The 걸 is from 것을 contracted; 그랬다 emphasizes the regret. Used after the fact, when speaker realizes a better choice was missed.

Key rule

STEM + -(으)ㄹ 걸 (그랬다) = regret 'should have ~'. Negative: -지 말 걸 (그랬다) 'shouldn't have ~'. Distinct from -(으)ㄹ 걸 'probably' (different tone / context). Often first-person; emotional / conversational.

Examples

일찍 잘 걸 그랬어요.

Key rule

STEM + -아/어 + 봤자 = 'no use even if you do ~'. Main clause typically NEGATIVE / dismissive (소용없다, 안 되다, 못 ~). Built from -아/어 보다 + -았자. Alternative: -아/어 봐야. Pessimistic concession; contrasts with neutral -아/어도.

Key rule

Vowel/ㄹ + -ㄹ 뿐(이다); consonant + -을 뿐(이다) = 'only / merely / that's all'. NOUN + 뿐이다 = 'only N'. Bare 뿐 used as connective. Distinct from 만 (simple only) and -(으)ㄹ 뿐만 아니라 (not only).

TOPIK 4 / B2Verb conjugation

Three-tense modifier review for action vs descriptive verbs (full paradigm)

관형형 종합 (시제별)

Korean modifier (관형형) endings encode TENSE on a verb / adjective modifying a noun. ACTION verbs: past -(으)ㄴ, present -는, future -(으)ㄹ. DESCRIPTIVE verbs (adjectives): present -(으)ㄴ, future -(으)ㄹ. Plus -던 (past imperfective) and -았/었던 (long-past). This tag consolidates the FULL paradigm.

Key rule

ACTION verb: past -(으)ㄴ / present -는 / future -(으)ㄹ. ADJECTIVE: present -(으)ㄴ / future -(으)ㄹ / past -았/었던. 있다/없다: present -는 (like verb). 이다: -인 (present). ㄹ-drop before -ㄴ. ㄷ/ㅂ/ㅅ irregulars apply.

Examples

어제 만난 친구가 한국 사람이에요.
어제 만나는 친구가 한국 사람이에요. (intended: 'met yesterday')
Verb past -(으)ㄴ. Translation: The friend I met yesterday is Korean. Romanization: Eoje mannan chingu-ga hanguk saram-iyeyo.

지금 본 영화가 재미있어요. (intended: 'watching now')
지금 보고 있는 영화가 재미있어요.
For PRESENT progressive use -고 있는, not past -(으)ㄴ.

TOPIK 4 / B2Verb conjugation

-던 (past imperfective modifier — recall, retrospective)

-던 (관형형)

STEM + -던 modifies a noun with a past, IMPERFECTIVE / RETROSPECTIVE meaning: '~ that used to / was being / is recalled as ~'. 자주 가던 식당 ('a restaurant I used to go to often'). Distinct from -(으)ㄴ (completed past).

Key rule

STEM + -던 = past IMPERFECTIVE / HABITUAL / RECALL modifier. Used for 'used to / was ~ing / recalled as ~'. Distinct from -(으)ㄴ (completed) and -았/었던 (completed long-past). No 으 insertion.

Examples

자주 가던 식당이 문을 닫았어요.
자주 간 식당이 문을 닫았어요. (intended: 'used to go often')

어렸을 때 좋아하던 노래.
Childhood / recurring habit → -던 (recalled).

TOPIK 4 / B2Verb conjugation

-았/었던 (past perfect modifier — long ago or completed)

-았/었던

STEM + -았/었던 modifies a noun with a COMPLETED LONG-PAST meaning, often emphasizing 'no longer current'. 어렸을 때 살았던 집 ('the house I LIVED in as a child — no longer'). Combines past -았/었 + retrospective -던 for stronger 'finished long ago' nuance.

Key rule

STEM + -았/었 + -던 = COMPLETED LONG-PAST modifier, often 'no longer current'. Adjective past state → -았/었던 (not -(으)ㄴ, which is present for adjectives). Distinct from -던 (habitual/lingering) and -(으)ㄴ (neutral past for verbs).

Examples

Key rule

Vowel/ㄹ + -ㄴ 채(로); consonant + -은 채(로) = 'in the state of having ~ed; with X on / leaving X as is'. Action A completed → state maintained while action B. ㄹ-drop. Distinct from -(으)면서 (simultaneous).

TOPIK 4 / B2Vocabulary usage

Advanced comparison (못지않다, 다름없다, 비교적, 한층 더)

비교 표현 (응용)

T4 expands comparison vocabulary: 못지않다 ('not inferior to / as good as'), 다름없다 ('no different from / virtually the same'), 비교적 ('comparatively / relatively'), 한층 더 ('even more / one step more'). Used for nuanced comparison beyond basic 보다.

Key rule

못지않다 = 'as good as / not inferior to' (N + 못지않다 / 못지않게). 다름없다 = 'no different from / equivalent to' (N + 와/과 다름없다). 비교적 = 'comparatively' (adverb). 한층 더 = 'even more / one step more' (intensifier).

-(으)ㅁ vs -기 — choosing between nominalizers

-잖아(요) (as you know / don't you remember — pragmatic appeal)

-잖아(요)

STEM + -잖아(요) appeals to SHARED KNOWLEDGE: 'as you know / don't you remember / isn't it ~'. 한국어가 어렵잖아요 ('Korean is hard, you know'). Used to soften disagreement, remind, or reason from shared ground. Casual = -잖아 (no -요).

Key rule

STEM + -잖아(요) = 'as you know / you remember / isn't it ~'. Pragmatic appeal to shared knowledge. Different from -지요? (asking confirmation) and -거든요 (giving new info). Casual = -잖아. Don't use with listener who doesn't know.

Key rule

STEM + -다는 + 점 + 에서/이/을 = 'in that / the point that ~ is ~'. VERB -ㄴ/는다는 점, ADJ -다는 점, NOUN -(이)라는 점, PAST -았/었다는 점. Formal / analytical use. Common with 인상적이다 / 특이하다 / 비슷하다 / 다르다 / 강조하다 / 인정하다.

-(으)라 (간접 명령)

STEM + -(으)라 is a DIRECT IMPERATIVE in LITERARY / WRITTEN / SIGN contexts: 가라! ('Go!'). 책을 읽으라 ('Read the book'). Distinct from spoken -(으)세요. Also used as the BASE form for indirect-quotation commands -(으)라고 하다.

Key rule

Vowel/ㄹ + -라; consonant + -으라 = LITERARY / WRITTEN imperative. ㄹ keeps. Used in slogans, signs, novels, indirect-command base (-(으)라고). Distinct from spoken -(으)세요 (polite) and -아/어라 (casual 반말). Negative: -지 말라.

-는데 / -(으)ㄴ데 advanced (discourse setup / floor-yielding / sentence-final hedge)

-는데 (담화 기능)

T2 introduced -는데 / -(으)ㄴ데 (setting / mild contrast). T4 covers ADVANCED discourse functions: opening with -는데 to give CONTEXT, ending with sentence-final -는데(요) to YIELD the floor / hedge politely, and SOFTENING tactics in conversation. 저... 부탁이 있는데요... ('Um, I have a favor...').

Key rule

-는데 / -(으)ㄴ데 = (1) mid-clause SETTING / CONTEXT / mild contrast, (2) sentence-final HEDGE / floor-yielding. Polite -는데요 trails softly. VERB + 있다/없다 → -는데; ADJ → -(으)ㄴ데; 이다 → -인데; PAST → -았/었는데.

-느라(고) (because of doing / while doing — often negative result)

-느라(고)

VERB stem + -느라(고) gives a CAUSE that is simultaneous with the main clause — typically explaining a NEGATIVE outcome ('I couldn't do X because I was doing Y'). 공부하느라고 잠을 못 잤어요 ('I couldn't sleep because I was studying'). Same subject; verb (action) base only.

Key rule

VERB stem + -느라(고) = simultaneous engagement → negative outcome. Same subject, action verb only. Main clause typically has 못 / 안 / -지 못하다. ㄹ keeps, no eu. Distinct from -아/어서 (neutral cause) and -(으)면서 (neutral simultaneous).

Examples

공부하느라고 잠을 못 잤어요.
어렵느라고 잠을 못 잤어요. (adjective)
Negative outcome. Translation: I couldn't sleep because I was studying. Romanization: Gongbuhaneurago jam-eul mot jasseoyo.

-아서/어서 vs -(으)니까 — subtle differences in cause (advanced)

-아서 vs -(으)니까 (응용)

Advanced contrast: -아서/어서 = OBJECTIVE / general cause; can't take commands. -(으)니까 = SUBJECTIVE / first-hand reason; freely takes commands. T4 adds nuances: SHARED knowledge, EMOTIONAL reactions, EXPLAINING new info, and pairing with various main clause types.

Key rule

-아/어서 = neutral/objective cause; no past inside; no commands. -(으)니까 = subjective/discovered reason; takes past inside (-았/었으니까); pairs with commands & proposals & discovery reading. Emotion cause → -아/어서; justified decision → -(으)니까.

Examples

비가 와서 못 갔어요.
비가 와서 우산 가져가세요.

TOPIK 4 / B2Verb usage

-지 않으면 안 되다 (must — double negative; obligation)

-지 않으면 안 되다

STEM + -지 않으면 안 되다 means 'must / have to ~' through DOUBLE NEGATION. Literally 'if not doing ~, it won't work'. 일찍 일어나지 않으면 안 돼요 ('I must get up early'). Equivalent to -아/어야 하다 / 되다 but more emphatic.

Key rule

STEM + -지 않으면 안 되다 = 'must / have to ~' (emphatic double negation). Equivalent to -아/어야 하다 / 되다 but stronger / more formal. Distinct from -(으)면 안 되다 ('must not'). Past: -지 않으면 안 됐다.

Examples

일찍 일어나지 않으면 안 돼요.

-(으)ㄹ 뿐(만) 아니라 (not only ~ but also)

-(으)ㄹ 뿐만 아니라

STEM + -(으)ㄹ 뿐(만) 아니라 means 'not only ~ but also ~'. Connects two clauses where the second adds MORE / additional info. 한국어가 어려울 뿐만 아니라 재미있어요 ('Korean is not only difficult but also fun'). NOUN + 뿐만 아니라 also works.

Key rule

Vowel/ㄹ + -ㄹ 뿐(만) 아니라; consonant + -을 뿐(만) 아니라; NOUN + 뿐(만) 아니라 = 'not only ~ but also'. The 만 is optional. Second clause often takes 도 / 까지. Distinct from -(으)ㄹ 뿐(이다) (only / merely).

그러므로 / 따라서

그러므로 ('therefore / hence') and 따라서 ('accordingly / therefore') are FORMAL written discourse connectors used in essays, reports, and logical arguments. Both link a conclusion to a previous statement. Sentence-initial.

Indirect speech strategies for politeness (-(으)ㄹ 수 있을까요, -아/어도 될까요)

간접화법 전략

Korean polite requests / questions use INDIRECT strategies to soften: -(으)ㄹ 수 있을까요? ('could you ~?'), -아/어도 될까요? ('may I ~?'), -아/어 주실 수 있을까요? ('could you do ~ for me?'). These layer multiple softening devices for maximum politeness.

Key rule

Polite indirect strategies: -(으)ㄹ 수 있을까요? (could you), -아/어도 될까요? (may I), -아/어 주실 수 있을까요? (could you do for me), -(으)면 안 될까요? (wouldn't it be ok), -(으)셨으면 좋겠습니다 (I'd appreciate). Stack with 혹시 / 죄송하지만 / 좀.

Dialect awareness — Gyeongsang / Jeolla / Jeju (recognition)

방언 인식 (중급)

Korean has several regional DIALECTS (사투리 / 방언). T4 introduces RECOGNITION of (1) 경상도 (Gyeongsang — southeast: Busan, Daegu), (2) 전라도 (Jeolla — southwest: Gwangju, Jeonju), (3) 제주 (Jeju Island — distinct). Standard 표준어 is based on Seoul speech. Learners recognize, don't actively produce.

Key rule

Korean dialects: 표준어 (Standard, Seoul), 경상도 (Busan/Daegu — tonal, 뭐 하노?), 전라도 (Gwangju — 잉 softener, 그라제), 제주 (Island — distinct vocab 혼저 옵서예). Learner level: RECOGNIZE; don't produce. Stick with 표준어.

Examples

(경상도) 뭐 하노?
(서울 사람에게 외국인이) 뭐 하노?
Gyeongsang 뭐 해? Translation: What are you doing? (Busan/Daegu). Romanization: Mwo hano?

TOPIK 4 / B2Vocabulary usage

Emotion / state idioms (속이 타다, 가슴이 아프다, 기가 막히다)

감정 관용 표현

Korean has rich EMOTION / STATE idioms beyond basic body-part expressions. T4 adds: 속이 타다 ('inside burns' = anxious / worried), 가슴이 아프다 ('heart hurts' = heartbroken), 기가 막히다 ('energy is blocked' = stunned / appalled), 머리가 아프다 (headache / troubled), etc.

Key rule

Emotion / state idioms = BODY + 이/가 + state verb. 속이 타다 (anxious), 가슴이 아프다 (sad/hurt), 기가 막히다 (stunned), 어이가 없다 (flabbergasted), 마음이 무겁다 (burdened), 정신이 없다 (frantic), 눈물이 나다 (moved to tears). Memorize as fixed.

TOPIK 4 / B2Vocabulary usage

Sino-Korean productive suffixes (-적, -성, -화, -감, -자, -계)

한자어 접미사 (-적/-성/-화)

T4 advanced SK suffixes that derive abstract nouns / adjectives: -적 (-ic / -al, makes adjective-like), -성 (-ness / nature), -화 (-ization / change), -감 (-ness / feeling), -자 (-er / -ist), -계 (-system / world). 사회적 (social), 가능성 (possibility), 현대화 (modernization), 책임감 (sense of responsibility).

Key rule

Productive SK suffixes: -적 (~ic / ~al, with 이다/으로/-ㄴ), -성 (~ness, abstract noun), -화 (~ization, with -하다/-되다), -감 (~feeling), -자 (~er person), -계 (~realm). Knowing morphemes + suffixes multiplies vocabulary recognition.

Examples

한국 사회의 문화적인 변화가 빠릅니다.
한국 사회의 문화 변화가 빠릅니다.
-적인 + N. Translation: Cultural changes in Korean society are fast. Romanization: Hanguk sahoe-ui munhwajeog-in byeonhwa-ga ppareumnida.
이 일이 성공할 가능성이 높아요.
성공할 가능이 높아요.
-성 abstract noun. Translation: This work has high possibility of success. Romanization: I ir-i seonggonghal ganeungseong-i nopayo.

Negative prefixes (불-, 무-, 비-, 미-)

부정 접두사

Four Sino-Korean NEGATIVE prefixes: 불- (not / un- / im-), 무- (without / -less), 비- (non- / un-), 미- (not yet / un-). 불가능 (impossible), 무관심 (indifferent), 비공식 (unofficial), 미완성 (incomplete). Each carries a distinct nuance.

Key rule

불- = 'not / un-' (strong negation: 불가능). 무- = 'without / -less' (absence: 무료). 비- = 'non-' (formal categorical: 비공식). 미- = 'not yet / un-' (incomplete: 미완성). Each pairs with specific roots; learn as lexicalized pairs.

Examples

이 일은 불가능해요.
이 일은 안 가능해요.
불-. Translation: This work is impossible. Romanization: I ir-eun bulganeunghaeyo.
이 행사는 무료로 진행돼요.
무공식적인 회의.
무-. Translation: This event is free. Romanization: I haengsa-neun muryo-ro jinhaengdwaeyo.
비공식적인 회의였어요.

wrong_prefix_pairing
무공식적인 회의.
비공식적인 회의.
공식 pairs with 비- for 'unofficial', not 무-.

TOPIK 4 / B2Writing system

Liaison (연음) and consonant assimilation (자음 동화)

연음 / 자음 동화

Korean SPELLING preserves morphemes, but PRONUNCIATION uses two main processes: (1) LIAISON (연음) — a final consonant before a vowel-initial syllable shifts to the next syllable. 한국어 → 한구거 [han-gu-geo]. (2) CONSONANT ASSIMILATION (자음 동화) — adjacent consonants influence each other: ㄴ + ㄹ → ㄹㄹ (편리 → 펼리), ㄱ + ㄴ → ㅇㄴ (한국 노래 → 한궁노래).

Key rule

Spelling preserves morphemes; pronunciation flows via LIAISON (받침 → next syllable) and ASSIMILATION (stops→nasals before nasals; ㄴ↔ㄹ → ㄹㄹ; ㄱ/ㄷ/ㅂ+ㅎ → ㅋ/ㅌ/ㅍ). Recognize for correct pronunciation; spelling unchanged.

Examples

한국어
한국어 spelled as 한구거.
Liaison: ㄱ → next syllable. Translation: Korean language Romanization: han-gug-eo (spelled), [한구거] han-gu-geo (pronounced)
책을
한국 노래 pronounced 한국 노래.
Liaison. Translation: (object) book Romanization: chaek-eul (spelled), [채글] chae-geul (pronounced)
한국 노래
입니다 pronounced 입니다 (with ㅂ).
Nasalization ㄱ → ㅇ. Translation: Korean song Romanization: hanguk norae (spelled), [한궁노래] han-gung-no-rae

Common mistakes

spelling_to_match_pronunciation
한국어 spelled as 한구거.
Spelled 한국어, pronounced [한구거].
Spelling preserves morphemes; pronunciation differs. Don't change spelling.
missing_assimilation
한국 노래 pronounced 한국 노래.
Pronounced [한궁노래] with nasalization.
ㄱ before ㄴ → ㅇ in connected speech.

TOPIK 4 / B2Writing system

Double batchim (겹받침) pronunciation rules

겹받침 발음

Korean has 11 DOUBLE BATCHIM (겹받침) — clusters of two final consonants in a syllable: ㄳ, ㄵ, ㄶ, ㄺ, ㄻ, ㄼ, ㄽ, ㄾ, ㄿ, ㅀ, ㅄ. Pronunciation rules depend on which consonant is dropped vs preserved. 앉다 → [안따]. 읽다 → [익따]. 짧다 → [짤따].

Key rule

겹받침 (double batchim) = 11 clusters. Word-end / pre-consonant: one consonant 'survives' (memorize per cluster). Before vowel: liaison splits cluster across syllables. Exceptions: 밟다 [밥따], 읽기 [일끼], 닭 [닥].

Examples

앉다
앉다 pronounced [안ㅈ다].
ㄵ → ㄴ before consonant. Translation: to sit Romanization: [안따] an-tta (word-end ㄴ)
앉아요
읽다 pronounced [읽다].
ㄵ liaison: ㄴ stays, ㅈ shifts. Translation: (sits) Romanization: [안자요] an-ja-yo (liaison)
많다
밟다 pronounced [발따].
ㄶ + 다 → ㄴ + ㅌ aspiration. Translation: many Romanization: [만타] man-ta

Common mistakes

missing_cluster_simplification
앉다 pronounced [안ㅈ다].
Pronounced [안따].
Word-end ㄵ → ㄴ; following ㄷ becomes ㄸ (tense).
missing_cluster_simplification
읽다 pronounced [읽다].
Pronounced [익따].
ㄺ word-end → ㄱ; following ㄷ → ㄸ.

TOPIK 4 / B2Writing system

Loanword orthography rules (외래어 표기법)

외래어 표기법

Korean has official ORTHOGRAPHY rules for transcribing FOREIGN words: vowels approximate Korean sounds (a → 아 / 어), consonants follow conventions (F → ㅍ, V → ㅂ, L/R → ㄹ, TH → ㅅ/ㄸ). 'coffee' → 커피, 'taxi' → 택시. Rules ensure consistency.

Key rule

Loanwords spelled per official 외래어 표기법: F→ㅍ, V→ㅂ, L/R→ㄹ, TH→ㅅ/ㄷ. Vowels approximate (a→아/어, e→에/이). Consonant clusters split into syllables. Avoid tensing in standard spelling. Memorize common words.

Examples

커피
커피의 영어 ☕는 'cofi'라고 적어요.
F → ㅍ. Translation: coffee Romanization: keo-pi
택시
텔레비전 → tellebijon (incorrect romanization)
TX split. Translation: taxi Romanization: taek-si
버스
택씨 (with double ㅆ).
B → ㅂ + final ㅡ support. Translation: bus Romanization: beo-seu

Common mistakes

false_assumption
커피의 영어 ☕는 'cofi'라고 적어요.
커피 = coffee (영어 spelling). 커피 is the Korean transliteration.
Korean spelling reflects pronunciation rules.
non_standard_correspondence
텔레비전 → tellebijon (incorrect romanization)
텔레비전 → tel-le-bi-jeon (with ㅂ for V).
V → ㅂ standard.

Advanced spacing 띄어쓰기 (auxiliaries, bound nouns, compound nouns)

띄어쓰기 (응용)

Korean SPACING (띄어쓰기) is famously tricky. Key advanced rules: (1) AUXILIARY verbs space from main verb (가 봤어요 / 먹어 보다). (2) BOUND NOUNS (것, 수, 적, 등) space from preceding modifier (좋은 것, 갈 수 있다, 간 적이 있다). (3) COMPOUND nouns often join (도서관 vs 도서 관). (4) Particles attach directly.

Key rule

Particles attach. AUXILIARY verb-pair spaces (가 봤어요). BOUND NOUNS space after modifier (좋은 것, 갈 수 있다, 간 적이 있다). 안/못 + V space (안 가요). Compound nouns joined if lexicalized. NUMBERS + COUNTER space (두 명).

Examples

책을 읽었어요.
가본적이있어요.
Particle attached. Translation: I read a book. Romanization: chaeg-eul ilgeosseoyo
가 봤어요.
좋은것을 골랐어요.
Auxiliary -아/어 보다 with space. Translation: I tried going. Romanization: ga bwasseoyo
좋은 것을 골랐어요.
갈수있어요.
Bound noun 것 with space. Translation: I chose a good one. Romanization: joeun geos-eul gollasseoyo

Common mistakes

missing_spaces
가본적이있어요.
가 본 적이 있어요.
Each bound noun + auxiliary should have spaces.

좋은것을 골랐어요.
좋은 것을 골랐어요.

Quotation marks 「」『』 and Korean punctuation conventions

인용 부호 / 문장부호 (응용)

Korean uses two sets of QUOTATION MARKS: '~' (single) and "~" (double) — same as English — plus traditional CORNER MARKS 「~」 (single) and 『~』 (double). Modern Korean also uses ENGLISH-style punctuation: period (.), comma (,), question mark (?), exclamation (!). Some specifics: 가운뎃점 (·) for lists, 줄임표 (...) for omission.

Key rule

Korean punctuation: "" / '' (Western) and 「」 / 『』 (traditional). 가운뎃점 (·) for tight lists. 줄임표 (... or ......) for omission. Same period/comma/?/!/dash as English. Titles: 『books』, 「articles」. No space before punctuation, space after.

Examples

친구가 "안녕하세요"라고 말했어요.
친구가 안녕하세요 라고 말했어요. (no quotes)
Direct quote. Translation: Friend said 'hello'. Romanization: Chingu-ga 'annyeong-haseyo' rago marhaesseoyo.
『한국어 문법』은 좋은 책이에요.
한국 문법은 좋은 책이에요. (book title without marks)
Book title corner marks. Translation: 'Korean Grammar' is a good book. Romanization: 'Hangugeo munbeop'-eun joeun chaeg-iyeyo.
한·중·일 회담이 열렸어요.
한중일 회담.
가운뎃점 for tight list. Translation: Korea-China-Japan talks were held. Romanization: Han-jung-il hoedam-i yeollyeosseoyo.

Common mistakes

친구가 안녕하세요 라고 말했어요. (no quotes)
친구가 "안녕하세요"라고 말했어요.
Add quotation marks around direct speech.
