How to Ask Really in Korean: 진짜요? and 정말요?
"Really?" in Korean is 진짜요? (jinjjayo?) or 정말요? (jeongmaryo?). Both work, both are polite, and you can use either one the next time someone tells you something surprising. The part no phrasebook mentions is that the word is the easy half. These are independent little words with no grammar attached — nothing to conjugate, nothing to attach them to — so what actually decides whether you sound surprised, skeptical, delighted or sad is your intonation. 진짜요? with your voice rising means "wow, seriously?" The exact same three syllables with your voice falling, 진짜요…, means "oh no, that's rough." Same word. Opposite conversation.
- Really? — 진짜요? (jinjjayo?)
- Really? (a touch more formal) — 정말요? (jeongmaryo?)
- Is that so? — 그래요? (geuraeyo?)
- Oh, really? — 아, 진짜요? (a, jinjjayo?)
- Really? (casual, to a friend) — 진짜? (jinjja?)
- No way / OMG — 헐! (heol!)
- Awesome, insane — 대박! (daebak!)
- Wow — 우와! (uwa!)
- That's right — 맞아요 (majayo)
- Ah, I see — 아, 그렇구나 (a, geureokguna)
진짜요? or 정말요? — which one to pick
They are near-synonyms, and no Korean will correct you for choosing the wrong one. If you want a tiebreaker:
진짜요? comes from 진짜, "the real thing," and it is the one you hear constantly in cafés, group chats and dramas. It is warm, spoken, slightly more emotional. Reach for this by default.
정말요? comes from 정말, "truly." It feels a half-step more composed — a little more at home in an office, with a client, or when speaking to someone noticeably older. It is also the one that sounds better when you genuinely need confirmation rather than when you are reacting: 정말요? 확인해 주실 수 있어요? ("Really? Could you check that for me?")
The pronunciation trap is 정말요. It is written 정-말-요 but it comes out of a Korean mouth as jeong-ma-ryo — the ㄹ slides over into the 요. Say "jeong-mal-yo" with a hard stop in the middle and it sounds stiff, which is the opposite of what the word is doing.

The rising and falling versions are different sentences
This is the whole skill, and it takes about thirty seconds to learn.
| What you do with your voice | What it means | When |
|---|---|---|
| 진짜요? ↗ | Really?! Seriously? | Good news, surprising news |
| 진짜요… ↘ | Oh… really. | Bad news, sympathy |
| 진짜요?! ↗↗ | No way | Something unbelievable |
| 진짜… flat, quiet | Ugh, come on | Frustration, not a question |
A friend says 나 다음 달에 한국 가요 ("I'm going to Korea next month"). You lift the end: 진짜요? — and the room gets brighter. A friend says 저 어제 지갑 잃어버렸어요 ("I lost my wallet yesterday"). You lift the end there and you have just congratulated them on losing their wallet. That one takes the falling version: 진짜요… ↘, soft, slower, almost a sigh.
English does this too, but it leans on extra words — "oh really," "wait, really?", "really…" Korean leaves the words alone and moves the pitch. If you only drill one thing out loud from this page, drill those two.
아, 진짜요? — the upgrade that costs one syllable
Put 아 (a) in front and the reaction stops sounding like a vocabulary item and starts sounding like a person.
아, 진짜요? — a, jinjjayo? — "Oh, really?" 아, 그래요? — a, geuraeyo? — "Oh, is that so?" 아, 정말요? — a, jeongmaryo? — "Oh, really?"
The 아 buys you a beat of thinking time and signals that you were listening before you answered. Koreans attach it almost reflexively, and adding it is the single fastest way to make your reactions sound native. It is a habit, not a rule — you will not be wrong without it, you will just sound like you are reading.
그래요? for when you are interested, not surprised
Not every piece of news deserves 진짜요?. If someone tells you a restaurant closes on Mondays, "Really?!" is too much face for the information. 그래요? (geuraeyo?) is the neutral one: "is that so," "I didn't know that." It acknowledges, it keeps them talking, it does not pretend to be amazed.
Two close relatives are worth having in the same pocket. 아, 그렇구나 (a, geureokguna) is "ah, I see" — the sound of a new fact landing, used with friends. 아, 그러셨어요? (a, geureosseosseoyo?) is "oh, is that what happened?", the polite version you use when someone older is telling you a story. And when you simply agree, 맞아요 (majayo) — "that's right" — does more for a conversation than any clever sentence. Reaction words are roughly half of everyday Korean, which is why they come up again in Korean small talk phrases for total beginners.
대박 and 헐 — the friends-only tier
Two reactions you will hear in every drama and should keep away from strangers:
대박! (daebak!) — originally "a jackpot," now "whoa, amazing, insane." For concert tickets, surprise good news, a ridiculous coincidence. 헐! (heol!) — an exhale of disbelief. Closest to "no way" or "OMG." Works for good shock and bad shock.
Both are slang with no polite form. 대박이에요 exists and is fine with coworkers your own age; 헐 does not have one, so it stays with friends and group chats. Said to your boss or a shop clerk, they land as oddly familiar rather than rude — but still off. More of this register is sorted out in Korean slang words and what they actually mean.
진짜 in front of a word means something else
Here is the split that confuses learners most. On its own with a question mark, 진짜요? asks "really?" In front of an adjective or verb, 진짜 is just the adverb "really," the same as "very":
진짜 맛있어요 — jinjja masisseoyo — "it's really delicious." 진짜 추워요 — jinjja chuwoyo — "it's really cold." 진짜 몰랐어요 — jinjja mollasseoyo — "I really didn't know."
So 진짜 stacks: 이거 진짜 맛있어요 → 진짜요? The first is describing, the second is asking. Its cousins are 너무 (neomu), "too / so," and 완전 (wanjeon), "totally" — 완전 맛있어요 is slangy and young, 너무 맛있어요 is safe everywhere.
How it sounds running
Good news, with a coworker:
Them: 저 다음 주에 승진해요. — jeo daeum jue seungjinhaeyo. — "I'm getting promoted next week." You: 아, 진짜요? 축하해요! — a, jinjjayo? chukahaeyo! — "Oh really? Congratulations!"
Plain information, in a shop:
Them: 이 가게는 월요일에 쉬어요. — i gageneun woryoire swieoyo. — "This shop is closed on Mondays." You: 아, 그래요? 알겠습니다. — a, geuraeyo? algesseumnida. — "Oh, is that so? Got it."
Bad news, with a friend:
Them: 나 어제 핸드폰 잃어버렸어. — na eoje haendeupon ireobeoryeosseo. — "I lost my phone yesterday." You: 진짜…? 괜찮아? — jinjja…? gwaenchana? — "Really…? Are you okay?"
Note the last one dropped the 요. 진짜? is the casual form, for friends and people younger than you; 진짜요? is the polite default for everyone else. That single syllable is the same ladder that runs through every Korean sentence you will build, mapped out in how to greet someone in different Korean politeness levels.
What goes wrong
Rising pitch on bad news. The most common and the most noticeable. A cheerful 진짜요? ↗ in response to someone's hospital story reads as excitement about it. Drop the ending.
Using 진짜요? for every single thing. Over-reacting to ordinary facts makes the big reactions worthless. Low-stakes information gets 그래요?.
Saying it as a flat statement. Korean questions are marked by pitch here, not by a question word. 진짜요 said flat is not a question at all — it reads as "yeah, for real," agreement.
Splitting 정말요 into three hard pieces. jeong-ma-ryo, one smooth motion.
대박 at a counter. Keep it for friends. A clerk telling you the total is not a jackpot.
Answering 진짜요? with silence. It is a real question and expects a real reply: 네, 진짜요 ("yes, really") or 진짜예요 ("it's true"). If you throw 진짜요? and then say nothing further, the other person assumes you doubt them.
The pitch is the part you have to say out loud
진짜요? is three syllables you can read in one second, and it is still the phrase learners most often get wrong in a live conversation — because the mistake is not in the word, it is in where your voice goes. You cannot check that on a page. Reaction words are also what makes you sound like you are following along, which is exactly what breaks down when the other person is going fast, as in Korean phrases when someone speaks too fast.
