Korean Superlatives: The Most (가장 / 제일)
가장 or 제일 before any adjective to express the absolute superlative 'most' in Korean.
Grammar Rule in 30 Seconds
Use '가장' (gajang) or '제일' (je-il) before an adjective or verb to express the superlative 'the most'.
- Place '가장' or '제일' directly before the adjective: '가장 예뻐요' (It is the prettiest).
- Use '제일' more often in casual, spoken Korean: '제일 좋아요' (It is the best).
- Use '가장' in formal writing or speeches: '가장 중요한 문제입니다' (It is the most important problem).
Overview
In any language, expressing the highest degree of a quality—the superlative—is a fundamental part of communication. When you want to identify something as the best, worst, fastest, or most beautiful, you are using a superlative. In English, this is often accomplished with the suffix "-est" (e.g., "fastest") or the word "most" (e.g., "most beautiful").
Korean simplifies this concept by using two primary adverbs: 가장 (gajang) and 제일 (jeil). These words function as universal markers for "the most," placed before an adjective or another adverb to elevate its meaning to the highest possible degree.
Understanding 가장 and 제일 is crucial for moving beyond simple descriptions into the realm of nuanced expression and opinion. The core principle is straightforward: you do not alter the adjective or adverb itself. Instead, you use 가장 or 제일 as a pre-modifier.
For instance, to change 비싸다 (to be expensive) into "the most expensive," you simply say 가장 비싸다 or 제일 비싸다. This structure is consistent and reliable, making it an accessible yet powerful tool for A2 learners.
While largely interchangeable in everyday use, a subtle distinction exists between them based on their origins. 가장 is a native Korean word, which lends it a slightly more neutral, and at times formal or literary, tone. 제일, on the other hand, is a Sino-Korean word derived from the Hanja characters 第一, literally meaning "number one" or "first in order." This origin gives 제일 a slightly more emphatic and colloquial feel, as if you are explicitly ranking something as number one.
This distinction is not critical for beginners, but it helps explain why you might hear 제일 more often in casual conversation among friends.
How This Grammar Works
가장 and 제일 is that of an adverb. Their sole purpose is to modify the word that follows them, which is typically a descriptive verb (adjective) or another adverb. Unlike English suffixes, which require you to remember spelling rules (e.g., happy -> happiest), Korean's adverbial approach means the adjective's form remains unchanged, regardless of its phonological structure (e.g., whether it ends in a vowel or consonant).가장 or 제일 directly before it, with a space in between. The rest of the sentence structure, including the subject, object, and verb endings, remains exactly as it would otherwise be.이 책이 재미있어요 (This book is fun), you already know how to say 이 책이 가장 재미있어요 (This book is the most fun).가장 and 제일 interchangeably without fear of making a mistake. Both are grammatically correct and will be perfectly understood. However, observing native speakers reveals a tendency to favor 제일 in spoken, informal contexts due to its punchy, definitive feel.가장 is often preferred in written language, such as news articles, academic papers, and formal announcements, where a more neutral and objective tone is desired.- Spoken preference:
오늘 날씨가 제일 덥네!(The weather is the hottest today!) - A common, natural utterance. - Written preference:
올해 여름은 기상 관측 이래 가장 더운 여름으로 기록되었습니다.(This summer was recorded as the hottest summer since weather observation began.) - A typical sentence found in a news report.
가장 and 제일 will become more intuitive as you are exposed to more native Korean content.Formation Pattern
가장 or 제일 before the word you wish to modify. There are no conjugations or exceptions to memorize for 가장 and 제일 themselves.
Subject + 가장/제일 + Adjective + Politeness Ending
요/어요/아요) is unaffected.
좋다 (to be good) | 좋아요 | 가장 좋아요 | It is the best. |
크다 (to be big) | 커요 | 제일 커요 | It is the biggest. |
빠르다 (to be fast) | 빨라요 | 가장 빨라요 | It is the fastest. |
덥다 (to be hot) | 더워요 | 제일 더워요 | It is the hottest. |
멀다 (to be far) | 멀어요 | 가장 멀어요 | It is the farthest. |
가장 and 제일 can also modify other adverbs to indicate the highest degree of an action.
Subject + 가장/제일 + Adverb + Action Verb + Ending
치타가 가장 빨리 달려요. (The cheetah runs the fastest.)
빨리 (quickly) | 가장 빨리 | 그가 가장 빨리 도착했습니다. | He arrived the fastest. |
많이 (a lot) | 제일 많이 | 제가 선물을 제일 많이 받았어요. | I received the most presents. |
열심히 (diligently) | 가장 열심히 | 그 학생이 가장 열심히 공부합니다. | That student studies the most diligently. |
가장 or 제일 does not dictate the politeness level; the sentence ending does. You can use superlatives across all levels of formality.
이 노래가 제일 좋다. | This song is the best. |
해체) | With close friends | 이 노래가 제일 좋아. | This song is the best. |
해요체) | General conversation | 이 노래가 제일 좋아요. | This song is the best. |
합니다체) | Presentations, news | 이 노래가 가장 좋습니다. | This song is the best. |
When To Use It
가장 and 제일 to state facts, express preferences, ask for recommendations, and describe experiences.저는 봄을 가장 좋아해요.(I like spring the most.)이 카페의 티라미수가 제일 맛있어요. 꼭 드셔보세요.(The tiramisu at this cafe is the most delicious. You should definitely try it.)어제 본 영화는 올해의 최고의 영화는 아니었지만, 가장 슬펐어요.(The movie I watched yesterday wasn't the best of the year, but it was the saddest.)
에베레스트 산은 세계에서 가장 높은 산입니다.(Mount Everest is the highest mountain in the world.)나일강은 지구상에서 제일 긴 강으로 알려져 있습니다.(The Nile River is known as the longest river on Earth.)통계에 따르면, 서울은 한국에서 인구가 가장 많은 도시입니다.(According to statistics, Seoul is the most populous city in Korea.)
서울에서 야경이 가장 아름다운 곳이 어디예요?(Where is the place with the most beautiful night view in Seoul?)이 메뉴 중에서 뭐가 제일 인기가 많아요?(Among the items on this menu, which is the most popular?)한국으로 가는 가장 싼 비행기 표는 어떻게 찾아요?(How do I find the cheapest plane ticket to Korea?)
Common Mistakes
가장/제일 directly before a noun, as in "the most students." This is grammatically incorrect in Korean because 가장 and 제일 are adverbs and cannot directly modify nouns.- Incorrect:
*저는 가장 책을 읽었어요. - Incorrect:
*교실에 제일 학생이 있어요.
가장/제일 can modify.- Correct:
저는 책을 가장 많이 읽었어요.(I read books the most. / I read the most books.) - Correct:
교실에 학생이 가장 많아요.(There are the most students in the classroom.)
최고 (choego)최고 (from Hanja 最高) also means "the best" or "the highest," but it functions differently. 최고 is a noun. This distinction is critical.가장/제일 (Adverb) | 최고 (Noun) |이다), or modifies a noun using 의. |이 가수는 노래를 가장 잘해요. (This singer sings the best.) | 이 가수는 최고예요. (This singer is the best.) |이 가수는 최고의 가수예요. (This singer is the best singer.) |이 가수는 가장이에요. | 이 가수는 최고 잘해요. (This is a common colloquial error, but is technically ungrammatical.) |가장 and 제일 are independent adverbs, they must have a space after them. Attaching them to the adjective is a common spelling mistake.- Incorrect:
이게 제일비싼 거예요. - Correct:
이게 제일 비싼 거예요.(This is the most expensive one.)
더 (deo)더 means "more." Since 가장/제일 already signifies the highest degree, adding 더 is redundant and incorrect. It is like saying "the most more expensive" in English.- Incorrect:
*이 건물이 가장 더 높아요. - Correct:
이 건물이 가장 높아요.(This building is the tallest.)
Real Conversations
Here is how superlatives appear in natural, everyday dialogues. Notice how 제일 is common in casual chats, while 가장 can appear in slightly more considered or formal contexts.
Scenario 1
Context: Two friends are texting to make dinner plans.
- A: 오늘 저녁 뭐 먹지? 매운 거 당기는데. (What should we eat for dinner? I'm craving something spicy.)
- B: 아, 그럼 새로 생긴 쭈꾸미 집 가볼래? 거기 후기가 제일 좋더라. (Oh, then do you want to try the new Jjukkumi (spicy webfoot octopus) place? It had the best reviews.)
- A: 오 진짜? 콜. 거기서 만나. (Oh really? Deal. Let's meet there.)
Scenario 2
Context: Fans talking about their favorite group online.
- A: 이번 앨범 컨셉 진짜 미쳤다. 난 수록곡 '별빛'이 가장 좋아. (This album's concept is insane. I like the B-side track 'Starlight' the most.)
- B: 인정! 근데 난 타이틀곡이 제일 신나서 계속 듣게 돼. (Agreed! But the title track is the most exciting so I keep listening to it.)
Scenario 3
Context: A team leader is giving feedback to a junior colleague.
- A: 이번 프로젝트에서 김대리님이 제안한 아이디어가 가장 창의적이고 효과적이었습니다. (In this project, the idea that you proposed, Assistant Manager Kim, was the most creative and effective.)
- B: 감사합니다, 팀장님. 팀원들이 도와준 덕분입니다. (Thank you, Team Leader. It was thanks to the help of my team members.)
Quick FAQ
가장 and 제일 really 100% interchangeable?In terms of grammatical correctness, yes. For an A2 learner, you can treat them as interchangeable. The difference is one of nuance and frequency. 제일 is statistically more common in daily speech, while 가장 appears more in formal writing and news. Using 가장 in a casual chat is not wrong, it just might sound slightly more formal than intended.
You use the adverb 덜 (deol), which means "less." The structure is the same: 가장 덜 or 제일 덜.
이 길이 가장 덜 막혀요.(This road is the least congested.)저는 채소 중에서 오이를 제일 덜 좋아해요.(Among vegetables, I like cucumbers the least.)
Absolutely. You can describe something as being the "most bad" or the "most un-delicious." The pattern works identically.
이 영화가 제가 본 영화 중에 가장 재미없었어요.(This was the most un-fun/boring movie I have ever seen.)어제 컨디션이 제일 안 좋았어요.(My physical condition was the worst yesterday.)
가장/제일 with action verbs like 가다 (to go) or 먹다 (to eat)?Not directly. 가장/제일 must modify an adverb that, in turn, modifies the verb. You use adverbs like 빨리 (fast), 늦게 (late), 많이 (a lot), 자주 (often).
그가 우리 반에서 가장 늦게 왔어요.(He came the latest in our class.)제가 우리 가족 중에서 밥을 제일 빨리 먹어요.(I eat meals the fastest in my family.)
가장/제일 relate to the comparative form -보다?They serve different functions. -보다 (boda) is comparative and is used to compare exactly two items ("A is more __ than B"). 가장/제일 is superlative and is used to single out one item from a group of three or more. You can, however, use them in the same sentence to build a more complex description.
- Comparative:
수박보다 딸기가 더 좋아요.(I like strawberries more than watermelon.) - Superlative:
과일 중에서 딸기를 가장 좋아해요.(Among all fruits, I like strawberries the most.)
