Korean -더라 and -더라고요: Reporting What You Saw Yourself

Quick answer: -더라고요 (-deoragoyo) means "I saw/found that…" — you are reporting something you personally witnessed or experienced, usually recently, usually a bit newly to you. 비가 오더라고요 = "It was raining — I saw it." In 반말 it's just -더라: 비 오더라.

If you watch K-dramas with subtitles, you've heard this ending hundreds of times and never seen it translated. A character comes back from somewhere, drops onto the sofa and says 그 사람 진짜 이상하더라. The subtitle says "That guy is so weird." True, but that's not what she said. She said: I met him, I watched him, and here is my verdict based on what I personally saw.

That's the one idea. -더- is the speaker's eyewitness stamp. It marks the information as coming from your own eyes, ears or experience, not from logic, not from gossip, not from general knowledge.

The forms you'll actually hear

Attach it straight to the verb or adjective stem: 오다 → 오더라, 맛있다 → 맛있더라, 바쁘다 → 바쁘더라. Past tense goes in front of it: 갔더라, 잘랐더라.

In fast speech and in texts you'll constantly see -더라구요. That's the spoken shape; -더라고요 is the standard spelling. Write the second one, expect to hear the first.

What it sounds like in real sentences

어제 민수 봤는데, 머리 잘랐더라. I saw Minsu yesterday — he'd cut his hair.

The 더라 is doing the work of "I saw that." Without it, 머리 잘랐어 is just a fact you know from somewhere.

그 카페 아침 아홉 시에 열더라고요. That café opens at nine in the morning — I noticed.

You were there. You saw the door open. Compare 아홉 시에 열어요, which is simply information, maybe read somewhere.

밖에 비 오더라. 우산 가져가. It's raining out there — take an umbrella.

This is a tiny act of kindness in grammar: I went outside, I checked, here's what I found.

사장님이 벌써 와 계시더라고요. The boss was already there (when I arrived).

Honorifics stack in front of it normally — 계시다 → 계시더라고요, 하시다 → 하시더라고요. If -(으)시- still feels slippery, the honorific -(으)시- explainer sorts that part out.

민지 씨가 그 얘기는 하지 말자고 그러더라고요. Minji said let's not talk about that.

Note the difference from reported speech: 그러더라고요 means I heard her say it with my own ears. For the full machinery of quoting people, see how to say "he said" in Korean.

-더라고요 vs 았/었어요 vs -대요

This is the comparison that makes the ending click.

A Korean picks 더라고요 when the point is the discovery. You're not stating a fact; you're handing over an impression you just formed, often with a flicker of surprise — it was better than expected, worse than expected, not what you'd assumed. That's why it sounds so natural after 생각보다 ("more than I thought"):

생각보다 춥더라고요. It was colder than I expected.

And it's why 더라 feels friendly. You're sharing, not informing. Saying 그 식당 비싸더라 to a friend is warm; 그 식당 비싸요 is a review.

The mistake learners make

Don't use -더라 for your own ordinary actions.

• ✗ 저는 어제 영화를 보더라고요.
• ✓ 저는 어제 영화를 봤어요.

You can't be an eyewitness to yourself doing something on purpose. To a Korean ear, 내가 밥을 먹더라 sounds like you watched yourself from the ceiling. Use plain past tense for what you did.

Feelings and impressions are the exception — those you genuinely discover inside yourself, so first person is fine:

저는 그 사람이 좀 부담스럽더라고요. I found him a bit much, honestly.

막상 가 보니까 좋더라고요. Once I actually went, I liked it.

Also note that Korean leaves the subject out constantly here — 비 오더라 has no "I," no "it." If that still feels like missing information, Korean sentences that drop 'I' and 'you' covers why that's normal.

The other 더라: "what was it again?"

There's a second, very common use that looks identical and means something completely different. -더라 in a question to yourself = digging through your own memory.

그 식당 이름이 뭐더라? What was that restaurant called again?

우리 몇 시에 만나기로 했더라? What time did we say we'd meet again?

내가 어디까지 얘기했더라? Where was I?

Said half under your breath, trailing off. You're not really asking the other person — you're searching your own head out loud. Drama characters do this while pacing around a room.

A quick word on -던데(요)

Same 더-, different ending. -던데요 reports what you saw and leaves a door open — a mild "but" or "so what do you think?"

아까 보니까 사람 많던데요. When I looked earlier, there were a lot of people — just so you know.

더라고요 closes the thought. 던데요 hands it to the other person to respond to. If you only learn one, learn 더라고요; 던데요 will start making sense once your ear is tuned.

FAQ

What does 더라 mean in Korean?

-더라 marks something you personally saw, heard or experienced and are now reporting. 맛있더라 means "I tried it and it was good," not just "it was good." It's 반말; the polite version is -더라고요. English has no single equivalent, which is why subtitles usually drop it.

What is the difference between -더라고요 and -았/었어요?

-았/었어요 is neutral past tense: the thing happened. -더라고요 adds that you witnessed it yourself and are sharing it as a fresh discovery, often with mild surprise. 비가 왔어요 is "it rained." 비가 오더라고요 is "I looked outside and it was raining."

Can I use -더라고요 about myself?

For your own deliberate actions, no — say 갔어요, not 가더라고요. For feelings, impressions and things you noticed about yourself, yes: 생각보다 힘들더라고요 ("it was harder than I expected") is completely natural.

1. 밖에 비 오더라.

2. 그 영화 생각보다 슬프더라고요.

3. 저는 어제 친구를 만났어요. (Your own action → plain past tense.)

4. 그 사람 이름이 뭐더라?

5. 사장님이 벌써 가셨더라고요.

Next time you watch something, listen for the 더라 at the end of a line and check what the subtitle did with it. Nine times out of ten it vanished — and now you know what vanished with it.
