Introduction to Limiting Particles
Choosing Just One
In Korean, you can add special particles ( 보조사 ) to nouns to give them extra shades of meaning. This lesson covers three important particles that help you single something out from a group: 만 , 밖에 , and 뿐 .
All three can be translated as 'only' or 'just', but they are used in different grammatical situations and carry slightly different nuances.
The 'Only' Particle: 만
The Most Common 'Only': 만
만 is the most straightforward and common way to say 'only' in Korean. It attaches directly to a noun, pronoun, or even other particles.
How it Works
만 can either replace the basic subject ( 이/가 ) and object ( 을/를 ) particles, or it can be added after location or time particles like 에 or 에서 .
Original · With 만 · Meaning
학생이 와요. · 학생만 와요. · Only the student comes.
커피를 마셔요. · 커피만 마셔요. · I drink only coffee.
주말에 쉬어요. · 주말에만 쉬어요. · I rest only on the weekend.
Key Characteristic
The most important thing to remember is that 만 is neutral. It works perfectly with both positive and negative sentences.
저는 사과만 먹어요.
저는 사과만 안 먹어요.
'Nothing But': 밖에 + Negative
The 'Only' with a Rule: 밖에
밖에 also translates to 'only', but it has one very important rule that you must follow.
The Golden Rule: 밖에 must always be followed by a negative predicate.
A negative predicate includes verbs like 없다 (to not exist), 모르다 (to not know), or verbs combined with 안 (not) or 못 (cannot).
만 vs. 밖에
While the meaning is often similar, the sentence structure is opposite. Using 밖에 with a positive verb is a very common mistake for learners.
With 만 (Positive Verb) · With 밖에 (Negative Verb) · Meaning
학생이 한 명만 있어요. · 학생이 한 명밖에 없어요. · There is only one student.
이것만 알아요. · 이것밖에 몰라요. · I only know this.
두 시간만 잤어요. · 두 시간밖에 못 잤어요. · I only slept for two hours.
'Just/Merely': 뿐
The 'Just/Merely' Particle: 뿐
뿐 is another way to say 'only', but it's typically used in a specific pattern and carries a nuance of 'merely' or 'just that and nothing more'.
Common Pattern: Noun + 뿐이다
The most common way you'll see 뿐 used is attached to a noun, followed by the copula 이다 (to be).
이것뿐이에요. (It's only this / This is all.)
농담일 뿐이에요. (It's just a joke.)
우리는 친구일 뿐이에요. (We are just friends.)
Using 뿐 often downplays the item or situation, emphasizing that it's not more than what is stated. For example, saying 'we are just friends' strongly implies 'we are not in a romantic relationship'.
For advanced learners
뿐 can also be used with verbs in the pattern -(으)ㄹ 뿐이다 to mean 'I just do X (and nothing else)'. For example: 저는 그냥 조용히 듣고 있을 뿐이에요. (I'm just listening quietly.)
