One lane per word — no nested boxes, just the gist.
A clause that modifies a noun, describing its attributes or state in detail
When to use
modifying nouns, adjective clause endings, before nouns
The nuance
관형절 precedes and directly modifies a noun, typically using adjective clause endings like '-는', '-던', or '-을'.
A clause that modifies verbs, adjectives, or entire sentences to express time, reason, condition, purpose, etc.
When to use
modifying verbs, modifying entire sentences, conjunctive endings
The nuance
부사절 modifies the main verb, adjective, or entire sentence, using conjunction endings like '-때문에', '-면', '-니까'.
나는 어제 읽은 책이 재미있었다.
na-neun eo-je ik-eun chaek-i jae-mi-iss-eoss-da., na neun eo je ik eun chaek i jae mi iss eoss da.
'읽은' is an adjective clause ending '-은' modifying the noun '책', so this is a 관형절.
나는 어제 읽은 책 때문에 늦었다.
na-neun eo-je ik-eun chaek ttae-mun-e neuj-eoss-da., na neun eo je ik eun chaek ttae mun e neuj eoss da.
'책 때문에' uses the conjunctive ending '-때문에' expressing reason, so this is a 부사절.
비가 오는 날 나는 집에 있었다.
bi-ga o-neun nal na-neun jip-e iss-eoss-da., bi ga o neun nal na neun jip e iss eoss da.
'오는' modifies the noun '날' with adjective clause ending '-는', so this is a 관형절.
비가 오기 때문에 나는 집에 있었다.
bi-ga o-gi ttae-mun-e na-neun jip-e iss-eoss-da., bi ga o gi ttae mun e na neun jip e iss eoss da.
'오기 때문에' uses the conjunctive ending '-기 때문에' expressing reason, so this is a 부사절.
나는 공부하는 동안 음악을 들었다.
na-neun gong-bu-ha-neun dong-an eum-ak-eul deul-eoss-da., na neun gong bu ha neun dong an eum ak eul deul eoss da.
'공부하는' modifies the noun '동안' with adjective clause ending '-는', so this is a 관형절.
나는 공부하는 동안 음악을 들었다.
na-neun gong-bu-ha-neun dong-an eum-ak-eul deul-eoss-da., na neun gong bu ha neun dong an eum ak eul deul eoss da.
This sentence combines 관형절 '공부하는' modifying '동안' which acts as a time-related 부사절; the structure is correct.
나는 공부하는 동안에 음악을 들었다.
na-neun gong-bu-ha-neun dong-an-e eum-ak-eul deul-eoss-da., na neun gong bu ha neun dong an e eum ak eul deul eoss da.
'동안에' forms a temporal adverbial clause, so this is a 부사절.
나는 공부하는 음악을 들었다.
na-neun gong-bu-ha-neun eum-ak-eul deul-eoss-da., na neun gong bu ha neun eum ak eul deul eoss da.
'공부하는 음악' is semantically odd since '공부하다' (to study) cannot naturally modify '음악' (music) here.
