있잖아, 그러니까 — Korean Filler Words in Real Conversations
Real Korean conversations are full of 있잖아, 그러니까, 뭐랄까, and 어. These filler phrases are what native speakers actually sound like — and learning them makes you sound natural fast.
You've studied Korean for a while. You can build sentences. You can answer questions.
But something feels stiff.
The missing piece is often filler — the small words and phrases that native speakers use to think aloud, hold the floor, and soften what they're about to say.
Korean has a rich set of these. Learning them won't help you pass a grammar test. But they'll make you sound like a real person in a real conversation.
The fillers
있잖아
Romanizationitjana
Meaningyou know / hey, listen / so, the thing is...
💡 Literally 'there is, you know.' Used to start a sentence when you want the other person's attention, or when you're about to say something a little tentative. 있잖아요 is the polite form. One of the most natural conversation openers in Korean.
그러니까
Romanizationgeureonikka
Meaningso / I mean / what I'm saying is
💡 Used to clarify, summarize, or restart a point you're making. Like 'so' or 'I mean' in English. Very common mid-sentence when the speaker is organizing their thoughts.
뭐랄까
Romanizationmworalkka
Meaninghow should I put it / what can I say
💡 Used when you're searching for the right word. 뭐랄까... signals a pause while you find language for something that's hard to describe. Very human, very natural.
어
Romanizationeo
Meaninguh / um
💡 The Korean equivalent of 'um.' A brief sound made while thinking. Very informal — you won't write it, but you'll say it constantly. 어... followed by the sentence is a completely normal speech pattern.
아 맞다
Romanizationa majda
Meaningoh right / oh, I forgot to mention
💡 Used when you suddenly remember something. Mid-conversation, you say 아 맞다 and then add what you just recalled. Natural, warm, very commonly said.
솔직히
Romanizationsoljikhi
Meaninghonestly / to be honest
💡 Used to signal that you're about to say something genuine or slightly vulnerable. 솔직히 말하면 = to be honest. Very common at the start of a frank statement.

Cultural note
Filler words don't appear in textbooks or grammar guides. But they're everywhere in real speech. If you listen to Korean conversations — in dramas, in cafes, between friends — you'll hear 있잖아 and 그러니까 constantly.
Using them signals fluency more than vocabulary does. It tells the person you're talking to: I know how conversations work in Korean. That's a big thing to signal.
Start with 있잖아 and 그러니까. Add 아 맞다. These three alone will change the texture of your spoken Korean immediately.
