Lesson 0 · Classroom Korean 20 교실 한국어 20 · 무료 · 10분 · 첫 사람 수업 전에

Your tutor speaks only Korean. Here are the 20 words you need.

Every Korean language school on earth teaches in Korean from day one — and it works, because the teacher only ever uses a few dozen words. These are ours. Learn the sound and the meaning; you never have to say the first 16, only understand them. (Audio: coming — your tutor is the audio for now.)

Why this works: Your tutor will use only these 20 words + the sentences of the lesson. Nothing else. So once these are familiar, you understand 100% of what she says. The English explanations are on your screen; the tutor is the voice.

A · What your tutor says (understand these)

1안녕하세요
an-nyeong-ha-se-yo
Hello
When: first second of every lesson. Say it back!

3따라 하세요
tta-ra ha-se-yo
Repeat after me
When: right after she says something. The most common instruction.
4다시
da-si
Again
When: one more time — not a complaint, just repetition.
5한 번 더
han beon deo
One more time
When: same as 다시, a little softer.

This one

10천천히
cheon-cheon-hi
Slowly
When: she'll say it slowly — or you ask her to (see B).
11크게
keu-ge
Louder
When: your mic is quiet. Not a criticism.
12좋아요 / 잘했어요
jo-a-yo / jal-hae-sseo-yo

Just a moment
When: she's typing in the chat or checking something.
16질문 있어요?
jil-mun i-sseo-yo?
Any questions?
When: end of a section. Answer 네 (yes) or 아니요 (no), or type it.

We're done
When: end of the lesson.
19수고했어요

Yes / No
When: everywhere. Nod = 네, shake = 아니요.

B · What YOU can say (4 phrases — also buttons on your screen)

다시 천천히요
da-si cheon-cheon-hi-yo
Again, slowly please
Use it: whenever she's too fast. She'll be glad you asked.
모르겠어요
mo-reu-ge-sseo-yo
I don't know
Use it: instead of silence. It's a real sentence and it moves things along.
잠깐만요
jam-kkan-man-yo
Just a moment
Use it: you need a second, or someone's at the door.
네, 알겠어요
ne, al-ge-sseo-yo
Got it
Use it: you understood. Better than nodding.
다시 천천히요Again, slowly
모르겠어요I don't know
잠깐만요Just a moment
네, 알겠어요Got it

In the live lesson these four are buttons under the video. Press one and it appears on your tutor's screen in Korean — no typing.

C · And when words fail

If…Do this
You don't understand an instructionPress I'm lost. The English explanation for the current slide appears again.
You have a "why?" questionPress Ask AI. You get an English answer without interrupting the tutor.
You need to tell the tutor something in EnglishType it in the chat. She sees it in Korean. Her reply comes back in English.
She says a sentence and you missed itLive subtitles under the video show her Korean with an English translation (2–4 s delay). Or press 다시 천천히요.
Nothing worksPoint, smile, say 모르겠어요. That is a completely normal Korean-class moment.
Self-check before your first live lesson: can you recognise 안녕하세요 · 따라 하세요 · 다시 · 좋아요 · 맞아요 · 질문 있어요? · 수고했어요 by sound? Yes → you're ready. (In the app this is a 2-minute listening quiz.)
