How Do You Say Daebak in Korean?

The everyday way to say daebak in Korean is 대박, used on its own as a reaction. It works like English "wow" or "no way", and the tone of voice shows if the news is good or shocking. To make it a full sentence, add 이다 and say 대박이다.

Building the sentence takes two steps:

1. Start with the noun 대박 ("a big hit").
2. Add 이다 ("to be"): after a consonant it joins as 이다, giving 대박이다, and polite 이에요 gives 대박이에요.

The word 완전 (wanjeon, "completely") is a slang intensifier that goes in front. 대박 can also sit before another noun to describe it, as in 대박 영화 (daebak yeonghwa, "a blockbuster film") and 대박 소식 (daebak sosik, "amazing news"). In that use it works like an adjective that means "huge" or "hit". The next section sets the forms out by use.

What Are the Casual Ways to Say Daebak?

Daebak is a casual word, so the choice is mostly about strength and ending. The guide to Korean speech levels explains casual speech (반말) and polite speech (존댓말). In short: use the bare form with friends and the 요 form with people you know a little.

Casual: 대박 (daebak)

대박 alone is a reaction. You say it when you hear surprising news, see a great result or watch something amazing. It needs no subject and no ending.

Casual: 대박이다 (daebagida)

대박이다 states that something is amazing. Add the thing first, as in 이 영화 대박이다, or add 완전 to raise the strength. Play

Casual: 완전 대박 (wanjeon daebak)

완전 대박 means "totally awesome" and is the strong version. It is common among young speakers and in variety shows, and it can end a sentence by itself. Play

Polite but Friendly: 대박이에요 (daebagieyo)

대박이에요 adds the polite 요 ending. It suits a coworker or a classmate you speak politely to but who is friendly. The word is still slang, so use it only where jokes and relaxed talk are normal. Play

Casual: 대박 사건 (daebak sageon)

대박 사건 names a huge event or a big incident, such as a scandal or a surprising turn. It sounds like "a big deal" in English.

Pronunciation comes next, because the spelling hides a sound change in the sentence form.

How Do You Pronounce 대박?

대박 is pronounced [대박], daebak in Revised Romanization, in two syllables: dae-bak. The vowel ㅐ sounds like the "e" in "bed", and the final ㄱ of 박 is a short, closed sound.

1. 대 (dae): a clear "deh" with a soft d.
2. 박 (bak): "ba" followed by a closed k, with the tongue stopped and no puff of air.

Do not add a vowel at the end: the word is not "daebaku". The final ㄱ is called unreleased, which means the sound is held and not exploded.

Sound Changes to Listen For

Two changes affect the forms on this page, following the National Institute of Korean Language Standard Pronunciation rules (표준 발음법):

• 대박이다 is [대바기다]. The final ㄱ of 박 moves into the next syllable, which has no sound of its own at the start. This is liaison, covered in the page on Korean liaison.
• 대박 사건 can sound like [대박 싸껀]. After a final ㄱ, a following ㅅ is always tense (Standard Pronunciation Article 23), and the dictionary pronunciation of 사건 also has a tense ㄱ [사껀]. The page on Korean tensification explains the pattern.

Revised Romanization writes 대박이다 as daebagida, matching the liaison. With the sounds in place, the next question is when 대박 fits.

When Should You Use 대박, and When Should You Not?

Use 대박 for good news, a surprise or a hit, and avoid it where a polite word is needed. Because it is slang, the listener matters more than the grammar.

Situations Where It Fits

• Good news from a friend. A passed exam, a new job or a lucky win all deserve a 대박!
• Reacting to a big surprise. A twist in a drama or a surprise party fits 완전 대박.
• Praising a hit. A film, a song or a shop that suddenly becomes popular is 대박 (and it is 대박 나다 when it succeeds).
• Shock that is not good. 대박... in a lower tone can mean "no way" when bad news arrives, as in the third dialogue below.

Situations to Avoid

• A business meeting or a formal speech. Use 대단하네요 (daedanhaneyo, "that is impressive") or 놀랍네요 (nollamneyo, "that is surprising").
• A first meeting with an older person. The slang tone may sound too relaxed.
• A condolence or a serious talk. The word can sound careless when someone shares real trouble.
• Every sentence. Overuse makes the word empty. Use it for peak moments.
