Korean Has 14 Words for 'Very.' Here's When to Use Each One.

너무, 정말, 진짜, 아주, 매우, 엄청, 되게, 완전, 굉장히, 참, 대단히, 무지, 몹시, 워낙. Fourteen options, fourteen different vibes. Pick the wrong one and you sound like a news anchor at a barbecue.

Every Korean learner picks up 너무 early. "Very good" = 너무 좋아요. Done. But then you hear 진짜 in a drama, 엄청 from a friend, 매우 on the news, 되게 in a vlog, and 완전 in a text message. They all seem to mean "very" or "really," but using the wrong one in the wrong situation makes you sound either like a textbook robot or a toddler borrowing slang. This guide covers all 14 Korean degree adverbs (정도부사), organized by formality, with real examples and the mistakes learners actually make.

The Big Four: 너무, 정말, 진짜, 아주

These are the four degree adverbs every learner encounters first. Each has a distinct personality.

너무 (neomu)

Original meaning: "excessively, too much" (negative). 너무 비싸다 = too expensive. For decades, using 너무 with positive words (너무 좋다) was considered incorrect by prescriptivists.

What changed: In 2015, the National Institute of the Korean Language (국립국어원) officially revised the definition to include positive contexts. 너무 좋다 (very good) and 너무 예쁘다 (very pretty) are now standard Korean. However, some older speakers and language purists still consider this usage informal or even wrong.

Formality: Neutral to casual. Fine in conversation, texts, and informal writing. Avoid in academic papers and formal speeches.

정말 (jeongmal)

Etymology: 정(正) "correct, true" + 말 "words." Literally: "true words." This gives 정말 a nuance that 너무 lacks. It does not just intensify; it affirms. "I really, truly mean it."

Formality: The most versatile of the Big Four. Works everywhere: casual conversation, polite speech, formal writing. If you are unsure which to pick, 정말 is the safest choice.

진짜 (jinjja)

Etymology: Originally a noun meaning "the real thing, the genuine article" (opposite of 가짜, "fake"). When used as an adverb, it carries a raw, emphatic energy: "for real, seriously."

Formality: Casual. Great in speech, texting, and drama dialogue. Avoid in TOPIK essays, business emails, and formal presentations. If you hear someone say 진짜 in a wedding speech, they are probably close friends with the couple.

아주 (aju)

Character: A pure intensifier. No "truly" or "really" nuance, no original noun meaning. 아주 simply means "very, completely." It is the most neutral and straightforward of the Big Four.

Formality: Neutral to slightly formal. Works in both spoken and written Korean. A reliable, safe choice in most situations. Less emotional than 너무, less sincere than 정말, less emphatic than 진짜.

The Formal Trio: 매우, 대단히, 몹시

These three live in the upper register of Korean. You will encounter them in news, literature, speeches, and formal writing. Using them in casual conversation sounds stiff.

매우 (maeu)

The formal "very." If 아주 is business casual, 매우 is a suit and tie. You see it in news articles, academic papers, weather forecasts, and product descriptions. You rarely hear it in everyday conversation.

대단히 (daedanhi)

From 대단하다 ("to be remarkable, tremendous"). 대단히 literally means "remarkably, tremendously." It is very formal and most commonly appears in polite fixed expressions.

몹시 (mopsi)

Means "severely, terribly." It has a distinctly negative or intense lean. You are more likely to see 몹시 춥다 (terribly cold) than 몹시 좋다 (terribly good). It lives mostly in literature and formal writing.

Tendency: Negative or emotionally heavy contexts. Hunger, cold, longing, exhaustion. Using 몹시 행복하다 is not wrong, but it sounds literary and dramatic.

The Casual Squad: 엄청, 되게, 완전, 무지

These are the words you hear in real Korean life: on the street, in cafes, in YouTube vlogs, and in group chats. They carry energy and personality. They also do not belong in formal writing.

엄청 (eomcheong)

From 엄청나다 ("to be enormous, absurd"). 엄청 conveys scale: "enormously, insanely." It is one of the most common casual intensifiers in modern Korean and often feels stronger than 너무.

되게 (doege)

A Seoul-dialect casual intensifier. Etymologically related to 되다 ("to become"), but in practice it just means "quite, really, pretty." It sits in a comfortable middle ground of casual Korean: not as strong as 엄청, not as loaded as 진짜.

완전 (wanjeon)

From the noun 완전 meaning "completeness." As an adverb, it means "totally, completely." It is slangy, emphatic, and very popular among younger speakers.

Formality: Very casual. Fine with close friends and in texts. Do not use in job interviews, formal emails, or TOPIK writing.

무지 (muji)

Means "extremely, tremendously." 무지 was once more widespread but is now somewhat regional and old-fashioned compared to 엄청. You will still hear it from older speakers and in certain dialects. Similar strength to 엄청.

Special Cases: 참, 굉장히, 워낙

These three do not fit neatly into the formal or casual categories. Each has a unique flavor that sets it apart.

참 (cham)

Means "indeed, quite, truly." 참 carries a warm, gentle emphasis. It often expresses genuine admiration or heartfelt feeling rather than raw intensity. You hear it frequently from older speakers, parents, and teachers.

굉장히 (goengjanghi)

From 굉장하다 ("to be magnificent, amazing"). Means "amazingly, incredibly." It sits in a useful sweet spot between formal and casual. You can use it in a news interview and also in a slightly polished conversation.

Why it is useful: 굉장히 is the go-to adverb when you need something stronger than 아주 but less stiff than 매우. Korean YouTubers, podcast hosts, and interviewees love it.

워낙 (wonak)

워낙 is unique. It means "inherently, by nature so much that." It does not just say something is extreme; it says it has always been that way, as if it is an intrinsic quality. This is a nuance that no other degree adverb carries.

The Formality Ladder

Here is where all 14 degree adverbs land on the formality spectrum. This is a general guide, not an absolute rule. Context always matters.

워낙 is not on this ladder because it works across registers. Its defining feature is the "by nature" nuance, not its formality level.
