Korean Fillers: Sound Natural with "you know" and "I mean"
Learn Korean filler words like 있잖아, 뭐랄까, and 그러니까 to hesitate, soften, and sound natural in intermediate conversation.
By TheaFirst conversations · Yapr Learn
Filler words are short expressions that give you a moment to think, soften what you say, or signal that more is coming. English uses "you know," "I mean," and "like." Korean has its own set, and using them well makes intermediate speech sound less textbook-like. This lesson focuses on fillers, not discourse markers that organize a whole argument. You will learn where each filler fits, how polite it sounds, and when to avoid it.
By the end, you can…
- use 있잖아 to share common ground or soften a statement in casual talk.
- use 뭐랄까 to hesitate while searching for the right words.
- use 그러니까 to clarify or restate what I mean.
- choose between casual and polite fillers based on the listener.
Listen once. Try it slowly. Then say it without looking.

있잖아
you know / hey, you know
it-jan-a
Very common in casual speech. It can open a sentence to get attention or signal shared knowledge. Avoid it in formal settings.
뭐랄까
how should I say it / I mean, like
mwo-ral-kka
Used when you are searching for the right expression. It sounds thoughtful rather than empty.
그러니까
I mean / so, what I'm saying is
geu-reo-ni-kka
Clarifies or restates a point. It can also mean "therefore," so context matters.
뭐 그냥
just, you know, whatever
mwo geu-nyang
Softens a vague or low-key answer. Common when you do not want to overexplain.
약간
kind of / sort of
yak-gan
Hedges adjectives and verbs. Very frequent among younger speakers in casual conversation.
Pronunciation guides are approximate. Slow playback keeps the original pitch.
Make it make sense
Useful pattern
Fillers often sit at the start of a clause or right before the key word. 있잖아 opens a turn: 있잖아, 오늘 좀 바빠. (You know, I'm a bit busy today.) 뭐랄까 appears when you hesitate: 뭐랄까, 그건 좀 어려운 질문이야. (How should I say it, that's a hard question.) 약간 goes before what you are softening: 약간 피곤해. (I'm kind of tired.) These fillers do not change the core meaning; they manage tone and timing.
When to use it
Use 있잖아 and 뭐 그냥 with close friends or people your age. With strangers, older people, or at work, use softer polite forms such as 있잖아요, 뭐랄까요, or 그렇죠 뭐. For example, a polite hesitation is 뭐랄까요, 제가 좀 더 생각해 봐야 할 것 같아요. (How should I say it, I think I need to think a bit more.) Too many fillers in one sentence can sound unsure, so use one or two per turn.
Listen to each line, then take one part and reply out loud.
있잖아, 이번 주말에 시간 있어?
You know, do you have time this weekend?it-jan-a, i-beon ju-mal-e si-gan i-sseo?뭐랄까, 토요일은 좀 바쁘고 일요일은 괜찮아.
How should I say it, Saturday is a bit busy and Sunday is okay.mwo-ral-kka, to-yo-il-eun jom ba-ppeu-go il-yo-il-eun gwaen-chan-a.그러니까 일요일이 낫다는 거지?
I mean, you're saying Sunday is better, right?geu-reo-ni-kka il-yo-il-i nat-da-neun geo-ji?응, 뭐 그냥 우리 집 근처에서 보자.
Yeah, let's just, you know, meet near my place.eung, mwo geu-nyang u-ri jip geun-cheo-e-seo bo-ja.A little context goes a long way
Korean fillers carry politeness levels. 있잖아 is fine with close friends but can sound rude to a boss or an older stranger; 있잖아요 is safer. 뭐랄까 and 약간 are common in casual speech and can sound youthful. In formal writing or presentations, reduce fillers and use clear connectors instead.
One thing to watch for
Using 있잖아 with a boss or an older stranger because it translates as "you know."
Try this instead: Use the polite form 있잖아요 or a neutral opener. For example, to a manager: 있잖아요, 잠깐 여쭤봐도 될까요? (You know, may I ask you something for a moment?)
Your turn
Try answering out loud before checking a possible answer.
1You want to hesitate politely while answering a teacher. Which filler fits best: 있잖아, 뭐랄까요, or 뭐 그냥?
Show a sample answer
뭐랄까요
뭐랄까요 is the polite hesitation form and fits a teacher or formal listener. 있잖아 is too casual, and 뭐 그냥 is vague and casual.
2Fill in the blank with a filler that softens an adjective: ___ 피곤해.
Show a sample answer
약간
약간 means "kind of" and softens 피곤해. Other hedges like 좀 can also work, but 약간 is the closest filler here.
3Your friend says something unclear, and you want to restate it. Which filler do you use?
Show a sample answer
그러니까
그러니까 introduces a clarification or restatement. It can also mean "therefore," so make sure the context shows you are clarifying.
Use Korean fillers to buy time and set tone, not to replace meaning. Match the politeness level: 있잖아 with friends, 있잖아요 or 뭐랄까요 in polite settings, and keep it to one or two per turn.
