Korean Particles Guide: How to Use Korean Particles [With Examples]

---

Korean particles attach to nouns and show how those nouns relate to the rest of a sentence. They can mark a topic, subject, object, location, direction, contrast and several other relationships.

An English preposition may be the closest translation in one example, but particles are not Korean versions of English articles or prepositions. Learn each form with its attachment rule, its job and a complete sentence.

This guide covers the contrasts that beginners meet most often. If you are new to the language, pair it with our practical beginner’s guide to Korean.

Read the examples aloud, then change one noun while keeping the particle and ending intact.

What Korean Particles Do

Most particles in this guide come directly after a noun phrase. They can mark grammatical roles such as subject and object, discourse roles such as topic and contrast, or relationships such as location and direction.

In 학교에 가요 (hakgyoe gayo, “I go to school”), 에 marks 학교 (hakgyo, school) as the destination. English uses “to”, but 에 also has time and static-location uses, so memorising “에 = to” would be too narrow.

Korean often omits a subject or object when the conversation makes it recoverable. A particle marks the noun that is present; it does not announce that another noun has been omitted. Context tells the listener what is understood.

How Many Korean Particles Are There?

There is no single useful total. Grammars differ over whether closely related forms, combinations and endings belong in the same category. A headline count such as 18 or 128 gives you less guidance than a list organised by function.

Start with the contrasts below. Add another particle when it solves a sentence problem you actually have.

Topic and Subject Particles

은/는 and 이/가 can point to the same noun while organising the message differently. The contrast is about topic, contrast, subject and focus; it is not a Korean version of Spanish ser versus estar.

Topic and Contrast: 은 / 는

Use 은 after a consonant-ending noun and 는 after a vowel-ending noun. The pair can set a topic, return to one, or contrast it with another possibility. Topics are often already active in the conversation, but 은/는 does not mean “known fact”.

• 저는 학생이에요. (Jeoneun haksaeng-ieyo.) “As for me, I’m a student.”
• 커피는 마시지만 차는 안 마셔요. (Keopineun masijiman chaneun an masyeoyo.) “I drink coffee, but I don’t drink tea.”

Subject and Focus: 이 / 가

Use 이 after a consonant-ending noun and 가 after a vowel-ending noun. This pair marks a grammatical subject. It often identifies the answer to “who?” or “what?”, presents something in the scene, or gives that subject narrow focus. It does not mean that the statement is temporary or uncertain.

• 누가 왔어요? 민지가 왔어요. (Nuga wasseoyo? Minjiga wasseoyo.) “Who came? Minji came.”
• 날씨가 추워요. (Nalssiga chuwoyo.) “The weather is cold.”
• 저는 한국어가 재미있어요. (Jeoneun hangugeoga jaemiisseoyo.) “As for me, Korean is interesting.”

The final example contains both a topic and a subject. That is why a one-line “old information versus new information” rule cannot cover the system.

Object Particles: 을 / 를

을 follows a consonant-ending noun and 를 follows a vowel-ending noun. They often mark the object affected by an action.

Korean commonly places a verb at the end of its clause, but particles carry useful role information when constituents move or are omitted.

저는 비디오 게임을 해요. (Jeoneun bidio geimeul haeyo.) “I play video games.”

In informal conversation, speakers sometimes omit a case particle when the role is clear. Learn the marked form first; omission depends on syntax, information structure and register rather than a rule that topics are normally dropped.

Time and Location: 에 and 에서

에 can mark a destination, a time, or the location of existence or a state:

• 학교에 가요. (Hakgyoe gayo.) “I go to school.”
• 책이 책상 위에 있어요. (Chaegi chaeksang wie isseoyo.) “The book is on the desk.”
• 세 시에 만나요. (Se sie mannayo.) “Let’s meet at three.”

에서 can mark the place where an action happens or the starting point of movement:

• 도서관에서 공부해요. (Doseogwaneseo gongbuhaeyo.) “I study at the library.”
• 부산에서 왔어요. (Busaneseo wasseoyo.) “I came from Busan.”

With plain 있다 for existence, use 에 for the location: 방에 사람이 있어요 (Bange sarami isseoyo), “There is a person in the room.” 여기서, 거기서 and 저기서 are shortened forms of 여기에서, 거기에서 and 저기에서 when 에서 has one of its valid functions.

Direction and Means: 으로 / 로

Use 으로 after a consonant except ㄹ. Use 로 after a vowel or a final ㄹ. The pair can mark direction, route, means, material, method or capacity; the surrounding noun and verb select the interpretation.

• 버스로 학교에 가요. (Beoseuro hakgyoe gayo.) “I go to school by bus.”
• 오른쪽으로 가세요. (Oreunjjogeuro gaseyo.) “Go to the right.”
• 서울로 출발해요. (Seoullo chulbalhaeyo.) “I leave for Seoul.”

Compare 학교에 가요, where 에 presents school as the destination, with 학교 쪽으로 가요, “I’m going in the direction of the school”. The forms overlap in some movement contexts but do not freely replace each other.

Possession and Relationship: 의

의 links one noun to another. Possession is one use, but the relationship can also be affiliation, origin, subject matter or another kind of association.

• 민지의 책 (Minjiui chaek) “Minji’s book”
• 한국의 역사 (Hangugui yeoksa) “the history of Korea”

As a particle, 의 is often pronounced [에] in ordinary speech, although [의] is also possible. Keep the spelling 의. Familiar relationships may omit it when the connection is clear.

• 나의 → 내 (naui → nae) “my”
• 저의 → 제 (jeoui → je) “my” in the polite/humble first-person set
• 너의 → 네 (neoui → ne) “your”; 네 is often pronounced [니] in conversation to distinguish it from 내

Noun Connectors and -고

과/와, 하고 and (이)랑 can join nouns or mark accompaniment. Their main difference is register and style, not whether the nouns have a logical relationship.

• 과 follows a consonant and 와 follows a vowel. The pair is common in writing and more formal or neutral contexts: 계란과 빵을 먹어요. (Gyerangwa ppangeul meogeoyo.) “I eat eggs and bread.”
• 하고 follows any noun and is common in conversation: 친구하고 영화를 봐요. (Chinguhago yeonghwareul bwayo.) “I watch a film with a friend.”
• 이랑 follows a consonant and 랑 follows a vowel. The pair is conversational and casual: 밥이랑 고기를 먹어요. (Babirang gogireul meogeoyo.) “I eat rice and meat.”

-고 is different: it is a connective ending on a verb or descriptive verb, not a noun particle. 책을 읽고 자요. (Chaegeul ilkko jayo.) means “I read a book and sleep.”

Korean Counting Words

Korean counters are bound nouns used after a number. They are not particles, even though beginner guides often teach them beside particles.

• People: 명 (myeong); honorific 분 (bun)
• Animals: 마리 (mari)
• General objects: 개 (gae)
• Books: 권 (gwon)
• Bottles: 병 (byeong)
• Vehicles and machines: 대 (dae)
• Clock hours: 시 (si)
• Duration in hours: 시간 (sigan)
• Minutes: 분 (bun)
• Age: 살 (sal)

Most counters in that list take native Korean numbers, with shortened forms such as 한, 두, 세 and 네 before a counter. Minutes take Sino-Korean numbers. Our Korean numbers guide teaches both systems.

• 저는 개가 두 마리 있어요. (Jeoneun gaega du mari isseoyo.) “I have two dogs.”
• 콘서트는 5분 후에 시작해요. (Konseoteuneun obun hue sijakaeyo.) “The concert starts in five minutes.”

개 is useful for general objects, but it is not a universal fallback for people, animals or every specialist category. Learn the counter with the noun you expect to count.

Korean Question Endings

The formal-polite question ending appears as -습니까? after most consonant-final verb or descriptive-verb stems and -ㅂ니까? after vowel-final stems. A final ㄹ drops before -ㅂ니까?, as in 살다 → 삽니까? (“Do [you] live?”). After the noun copula, the corresponding form is 입니까?

음식이 있습니까? (Eumsigi itseumnikka?) “Is there food?”

In informal-polite speech, 음식이 있어요? (Eumsigi isseoyo?) can be a question through the ending, intonation and context. It does not contain a separate “question particle”.

-(으)ㄹ까요? is another ending. It can make a suggestion or ask for the listener’s view about a possible action. Use -을까요 after a consonant other than ㄹ, add -ㄹ까요 after a vowel, and add -까요 after a stem that already ends in ㄹ.

• 먹을까요? (Meogeulkkayo?) “Shall we eat?”
• 갈까요? (Galkkayo?) “Shall we go?”

Three More Useful Particles

도: “also” or “too”

도 can replace a topic, subject or object particle in many positions, and it can combine with some location forms such as 에도 and 에서도.

저도 커피를 좋아해요. (Jeodo keopireul joahaeyo.) “I like coffee too.”

까지: “until”, “as far as” or “up to”

오후 7시까지 일했어요. (Ohu ilgop sikkaji ilhaesseoyo.) “I worked until 7 pm.”

만: “only”

드라마만 봐요. (Deuramaman bwayo.) “I only watch dramas.”

How to Practise Korean Particles

1. Learn one pair with its attachment rule, such as 은 after a consonant and 는 after a vowel.
2. Compare two sentences that change the function, not just the noun.
3. Save a line from audio and underline the noun-plus-particle unit.
4. Change one element, say the new sentence aloud and ask a tutor or language-exchange partner what the change implies.

The Basic Korean Dictionary’s advanced search lets you filter for postpositional particles and inspect their separate meanings and examples. That is more reliable than forcing one English translation onto every use.
