Korean Particles Guide: 은/는, 이/가, 을/를 Explained
Master Korean particles 은/는, 이/가, 을/를, 에, 에서 and more. Learn how particles work in sentences with examples from K-dramas.
Korean particles are small but mighty. They attach directly to nouns to show their role in a sentence — who's doing the action, what's being acted on, where something is happening. Unlike English, which uses word order to show these relationships, Korean uses particles. Once you understand them, Korean sentences start to make much more sense.
What Are Particles?
Particles (조사, josa) are grammatical suffixes that glue directly onto the end of a noun. They don't stand alone — they always attach to the noun they modify.
Because Korean uses particles to mark grammatical roles, the subject can appear anywhere in the sentence. This flexibility allows for the dramatic, poetic sentence structures you hear in K-dramas.
Particle (grammar)
Final consonant of a syllable
받침이 있으면 '은', 없으면 '는'
bat-chim-i i-sseu-myeon 'eun', eom-seu-myeon 'neun'
If there's a final consonant, use '은'; if not, use '는'
은/는 vs 이/가 — Topic vs Subject
This is the most confusing distinction for learners. Both 은/는 and 이/가 can translate to 'is' or mark the subject, but they carry different nuances.
은/는 (topic marker): Used to introduce or contrast the topic of the sentence. Often implies 'as for...' or 'speaking of...'. Also used for contrast ('But X is...').
이/가 (subject marker): Used when introducing new information, emphasizing the subject, or in answer to 'who/what did something?'
The choice of particle depends on
batchim(final consonant): 은/이 after a consonant, 는/가 after a vowel.
저는 한국어를 공부해요.
Jeo-neun han-guk-eo-reul gong-bu-hae-yo.
I study Korean. (topic: 'as for me')
저 ends in a vowel → 는
제가 했어요!
Je-ga haet-seo-yo!
I did it! (emphasizing subject)
이/가 used for emphasis or new info
커피는 좋아하는데, 차는 별로예요.
Keo-pi-neun jo-a-ha-neun-de, cha-neun byeol-lo-ye-yo.
I like coffee, but tea not so much.
는 used twice for contrast
을/를 — Object Markers
을/를 marks the direct object of a verb — what the action is done to. 을 attaches after a consonant (받침), 를 after a vowel.
In casual speech, 을/를 is very often dropped entirely. You'll hear this a lot in K-drama dialogue between friends.
영화를 봤어요.
Yeong-hwa-reul bwat-seo-yo.
I watched a movie.
영화 ends in a vowel → 를
밥을 먹었어.
Bab-eul meok-eot-seo.
I ate rice/a meal.
밥 ends in consonant ㅂ → 을
너 좋아해.
Neo jo-a-hae.
I like you.
너 (you) has 를 dropped — very common in casual speech
에 and 에서 — Location Particles
Both 에 and 에서 relate to location, but they have distinct uses:
에→ static location (where something exists/is) or direction (destination of movement)
에서→ active location (where an action takes place)
Think of it this way: if there's motion or action happening at a place, use 에서. If you're just stating where something is or where you're going to, use 에.
카페에 가요.
Ka-pe-e ga-yo.
I'm going to the café.
에 = destination
카페에 있어요.
Ka-pe-e it-seo-yo.
I'm at the café.
에 = static location with 있다
카페에서 공부해요.
Ka-pe-e-seo gong-bu-hae-yo.
I study at the café.
에서 = location where action happens
