'은/는' VS '을/를'

Many Korean learners find it difficult to distinguish between '은/는' and '을/를' for several reasons:

1. They look similar, which makes them easy to mix up.

2. English does not have this kind of particle, so using them feels unfamiliar.

3. Learners may not fully understand grammatical roles, such as:

• What is a verb (동사) vs. an adjective (형용사) ?
• What is the subject (주어) vs. the object (목적어) ?

Since these particles depend on the sentence structure, 

understanding how verbs, adjectives, subjects, and objects work in Korean is crucial. 

Let’s break them down step by step!

1. '은/는'

- '은/는' is used when a noun is subject (주어) of a sentence.

- '은' is used after consonants, and '는' is used after vowels.

< How to Identify a Subject (주어) >

1) The subject (주어) is who or what is performing the action in the sentence.

- 제니는 책을 읽어요. (제니 reads a book.) 

- In this sentence, the subject is 제니 because she is the one performing the action.

2) The subject can also be the noun that a sentence describes (even if there is no action.)

- 날씨는 추워요. (The weather is cold.)

- In this sentence, the subject is '날씨' (the weather), which is simply the noun being described.

- Even though '추워요' is not an action, the sentence still needs a subject ('날씨') to describe what is cold.

- Therefore, '은/는' can be used with adjectives.

< Then, How Can You Tell if a Word is an Adjective (형용사)? >

-  Adjectives (형용사) Describe a State or Condition

-  Adjectives describe what something is like rather than an action

-  Adjectives often translate as "to be [adjective]" in English

- Common Adjectives:

: 크다 (to be big)  → 이 집은 커요. (This house is big.)

: 예쁘다 (to be pretty)  → 이 꽃은 예뻐요. (This flower is pretty.)

: 덥다 (to be hot)  → 오늘 날씨가 더워요. (Today’s weather is hot.)

- Therefore, if there is an adjective, the subject marker ('은/는' or '이/가') must be used!

- The difference between '은/는' and '이/가' is explained in another post, so please check it out!

< Examples >

- 저는 한국어를 배워요. (I learn Korean.)

- 이 영화는 재미있어요. (This movie is interesting.)

- 하늘은 파래요. (The sky is blue.)

- 준영 씨는 영화를 봐요. (준영 watches a movie.)

2. '을/를'

- '을/를' is used when a noun is the object (목적어) of a verb (동사).

- '을' is used after a consonant, and '를' is used after a vowel.

< How to Identify an Object (목적어) >

- The object (목적어) is what receives the action of a verb.                                                                    

- In English, the object usually comes after the verb. 

- I eat an apple. (Subject + Verb + Object)

- However, in Korean, the object comes right before the verb.

- 저는(주어) 사과를(목적어) 먹어요(동사).

< Then, How Can You Tell if a Word is a Verb(동사)? >

- Verbs are related to actions, not describing a state.

- Verbs are used when something/someone performs an action.

- Verbs often translate as action words in English

- Common Verbs:

:  먹다 (to eat) → 저는 사과를 먹어요. (I eat an apple.)

:  배우다 (to learn) → 저는 한국어를 배워요. (I learn Korean.)

:  읽다 (to read) → 저는 책을 읽어요. (I read a book.)

- Most verbs do require an object.

< Example >

- 지민 씨가 가방을 사요. (지민 buys a bag.)

- 학생들이 한국어를 공부해요. (The students study Korean.)

- 리쿠 씨가 블랙핑크 노래를 불러요. (Riku sings a BLACKPINK song.)

- 쇼타로 씨가 공을 찼어요.  (Shotaro kicked the ball)
