Korean Comparatives and Superlatives 더 가장: Meaning, Rules and Examples

Korean comparatives and superlatives 더 가장 are built by placing 더 ("more") or 가장 ("most") before an adjective or an adverb. Say 이 가방이 더 비싸요 for "This bag is more expensive" and 이게 제일 맛있어요 for "This is the tastiest." After this lesson you can build both patterns and name what you compare.

What you'll learn

• Build a comparative with 더 or 덜 and name the standard with 보다.
• Build a superlative with 가장 or 제일 and name the group with 중에서 or 에서.
• Choose between 더 and 가장 by counting the items you compare.
• Diagnose the error in 비싸더요 and fix it.

Before you start: you can say simple sentences with adjectives, such as 비싸요 (is expensive), and know the subject particle 이/가. Estimated time: 20 minutes.

What Does Korean Comparatives and Superlatives 더 가장 Mean?

Korean comparatives and superlatives 더 가장 mean "more" and "most". A comparative says that one thing has more of a quality than another. A superlative says that one thing has the most of a quality in a whole group. In English, endings such as -er and -est do this work ("bigger", "biggest"). Korean uses separate adverbs instead and leaves the adjective unchanged.

An adverb of degree is a word that tells you how much or how strongly, and it stands before the adjective or verb. 아주 (very) and 너무 (too) are adverbs of degree you may know, and the lesson on korean adverbs of degree 아주 너무 정말 covers them. 더 (more), 덜 (less), 가장 (most) and 제일 (most) belong to the same group. They work like volume knobs for the adjective that follows.

A First Example

The two sentences below show one comparative and one superlative. Read the Korean first, then the romanization, then the meaning.

• 이 가방이 더 비싸요. (i gabangi deo bissayo) [이 가방이 더 비싸요] = "This bag is more expensive." Word by word: 이 가방 (this bag) + 이 (subject) + 더 (more) + 비싸요 (is expensive).

• 이게 제일 맛있어요. (ige jeil masisseoyo) [이게 제일 마시써요] = "This is the tastiest." Word by word: 이게 (this one, short for 이것이) + 제일 (most) + 맛있어요 (is tasty).

Notice two things. First, the adjectives 비싸요 and 맛있어요 do not change at all: the adverb carries the comparison. Second, the spoken form 이게 is a short form of 이것이 (this thing + subject particle), and the sound of 맛있어요 is [마시써요]. With the meaning in place, the next section shows how to build the patterns.

How Do Korean Comparatives and Superlatives 더 가장 Work?

Korean comparatives and superlatives 더 가장 work by putting one adverb before the predicate and, if needed, naming what you compare. The adjective keeps its normal polite ending, so you only conjugate it as you would in a simple sentence.

1. Name the thing you describe: 이 가방, 서울, 사과.
2. Add the subject or topic particle: 이/가 or 은/는.
3. Choose the adverb: 더 or 덜 for a comparison, 가장 or 제일 for the top of a group.
4. Add the adjective or verb in its polite form: 비싸요, 커요, 좋아요.
5. Name the standard with 보다 (for a comparison) or the group with 에서 or 중에서 (for a superlative).

Pattern Table

The table shows the five patterns with one example each. Brackets show how the phrase sounds where it differs from the spelling.

The pattern table shows that the adverb sits in the same place in every row: right before the predicate. The standard and the group come earlier in the sentence and carry their own particles.

Which Adjectives Change Their Form?

Adjectives keep their normal polite form, including the irregular ones. The adverb 더 does not trigger any change.

The table shows that the ㅂ irregular adjectives (맵다, 덥다, 춥다) change their ending as usual, and 더 stays in front. The sentence 여름이 더 더워요 has two different words that look alike: the first 더 means "more" and the second 더워요 means "is hot". The form rule is complete, so the next section builds one full sentence from scratch.

Worked Example, Step by Step

This worked example builds 이 가방이 저 가방보다 더 비싸요 ("This bag is more expensive than that bag") from its parts. Each step names one decision, so you can repeat the process with any two things.

1. Choose the two things. You compare this bag with that bag.
2. Pick the one that has more. This bag is the one that is more expensive, so it is the subject: 이 가방이.
3. Name the standard. The bag you compare against is 저 가방 (that bag over there). Attach 보다 ("than") to it: 저 가방보다.
4. Add the adverb. For a comparison, use 더 ("more"): 더.
5. Choose the adjective. 비싸다 (be expensive) in the polite present is 비싸요.
6. Put the verb last. Korean ends with the predicate: 이 가방이 저 가방보다 더 비싸요.
7. Check what is optional. With 보다, the adverb 더 is optional: 이 가방이 저 가방보다 비싸요 is also correct. Without 보다, 더 is needed to signal the comparison.
8. Say it aloud. The phrase is [이 가방이 저 가방보다 더 비싸요], with no sound change.

You'll know it worked when you can swap the parts and still choose correctly. Replace 비싸요 with 커요 and you get 이 가방이 저 가방보다 더 커요 ("bigger"). Replace 더 with 제일 and remove the standard, and you get 이게 제일 맛있어요 (ige jeil masisseoyo), "This is the tastiest."

The same steps also build a superlative with a group. Name the group first and add 중에서 ("among"), then the item with its particle, then 제일 or 가장, then the adjective. 과일 중에서 사과가 제일 좋아요 (gwail jungeseo sagwaga jeil joayo) means "Among fruits, I like apples best." For a place or an organisation, use 에서 instead of 중에서: 서울은 한국에서 가장 큰 도시예요 (seoureun hangugeseo gajang keun dosiyeyo) means "Seoul is the biggest city in Korea."

Once you can build the patterns, the next question is how 더 and 가장 differ from the particles that sit around them.

How Is 더/가장 Different from Similar Forms?

The adverbs 더 and 가장 go before the predicate, while the particle 보다 follows the standard and the phrase 중에서 names the group. Four pieces often appear together, and the table puts them side by side.

The test is the job each piece does. Ask whether you are intensifying the adjective (더, 가장), naming the thing you compare against (보다) or naming the group (중에서). A sentence can use one adverb and one particle. In the sentence 과일 중에서 사과가 제일 좋아요, the adverb 제일 does the "most" work, and 중에서 sets the group. The sibling lesson on the comparison particle 보다 covers the particle in full.

Two other comparison patterns are worth knowing. The particle 처럼 expresses likeness, as in 아이처럼 (like a child), and the lesson on the 처럼 like particle explains it. The equal comparison "as much as" uses 만큼, which the lesson on 처럼 vs 같이 vs 만큼 compares. The comparison is clear, so the next section collects the limits of the rule.

When Do You Use 더 and 가장, and When Not?

Use 더 when you compare two things, and use 가장 or 제일 when you pick the top item from three or more. Beyond that core job, a few extra points control the choice.

What Is the Difference between 가장 and 제일?

가장 and 제일 mean the same, and either one is correct in any sentence. 가장 is neutral and appears often in writing, reports and careful speech: 가장 중요한 것 (the most important thing). 제일 is more spoken: 제일 좋아해요 (I like it best). Choose either one, and use the other when you want a change of style. The phrase 가장 좋아하는 음식 (the food I like most, or my favourite food) is a very common pattern.

Does 더 Work with Verbs and Quantities?

Yes. 더 also means "more" or "further" with verbs and amounts. 더 주세요 (deo juseyo) means "Please give me more", and 더 먹어요 means "I eat more." In this use, 더 stands before the verb and does not need 보다. The adverb 훨씬 더 (much more) and 조금 더 (a little more) add strength: 이게 훨씬 더 비싸요 means "This one is much more expensive."

Cases Where the Rule Does Not Fit

• Two items with a superlative. Use 더 for two items and 가장 for three or more. 두 사람 중에서 민수가 더 커요 (Of the two, Minsu is taller) is correct. 가장 would suggest a group of at least three.
• Nouns after 더. 더 does not attach directly to a noun to mean "more of it". Say 책을 더 주세요 (give me more books), with the object particle in place.
• Written style. In formal writing, 더욱 (even more) and 가장 are common. In casual speech, 훨씬 and 제일 are common.

One honest limit: the rule "two items take 더, three take 가장" is a teaching guide. Native speakers also use 제일 for a group of two in casual talk, for example 둘 중에서 이게 제일 나아요. The safe beginner habit is to follow the rule and to recognise the exceptions when you hear them. With the uses sorted, the next section lists the mistakes that come from mixing them up.

What Mistakes Do Learners Make?

Learners make four common mistakes with 더 and 가장. Each one follows the pattern "learners often assume X; actually Y, because Z".

1. Adding an English-style ending. Learners often assume the adjective must change, so they write 비싸더요 or 크더요. Actually the comparison lives in the adverb 더 and the adjective stays plain. Write 더 비싸요, 더 커요.
2. Putting 보다 on the wrong noun. Learners write 저 가방이 이 가방보다 더 비싸요 when they mean that this bag is more expensive. Actually the noun with 보다 is the standard, the one that is less. Write 이 가방이 저 가방보다 더 비싸요.
3. Using 가장 with two items. Learners write 둘 중에서 가장 커요. Actually a superlative needs a group of three or more in the classroom rule, so use 더: 둘 중에서 더 커요.
4. Placing 더 before a noun. Learners write 더 책 for "more books". Actually 더 modifies adjectives, adverbs and verbs, not bare nouns. Write 책을 더 주세요 or 더 많은 책.

A practical rule of thumb: count the items you compare. Two items need 더, and three or more need 가장 or 제일. The practice below checks both halves of that rule.

Practice and Answers

These four exercises check the core outcome: using 더 and 가장 in a new sentence and explaining how they differ from 보다 and 중에서. Try each one before reading the answers.

Exercise 1: Choose the adverb. Fill in the blank with 더 or 가장: 두 사람 중에서 민수가 __ 커요. (Of two people, Minsu is taller.)

Exercise 2: Fix the error. A learner writes 이 가방이 비싸더요 for "This bag is more expensive". Correct it.

Exercise 3: Translate. "Summer is hotter than spring." (summer = 여름, spring = 봄, is hot = 더워요)

Exercise 4: Write your own. Write one sentence that says which Korean food you like best (food = 음식, like = 좋아요, bibimbap = 비빔밥).

Answer Key

• Exercise 1: 민수가 더 커요. Two people make a comparison, so 더 fits. 가장 would suggest a group of three or more.
• Exercise 2: 이 가방이 더 비싸요. (i gabangi deo bissayo) The adjective stays 비싸요, and the adverb 더 goes in front of it.
• Exercise 3: 여름이 봄보다 더 더워요. (yeoreumi bomboda deo deowoyo) [여르미 봄보다 더 더워요] Summer is the subject with 이, spring is the standard with 보다. The word 더워요 is the ㅂ irregular form of 덥다.
• Exercise 4: One model answer: 한국 음식 중에서 비빔밥이 제일 좋아요. (hanguk eumsik jungeseo bibimbabi jeil joayo) [한국 음식 중에서 비빔빠비 제일 조아요] = "Among Korean foods, I like bibimbap best." The group takes 중에서, the favourite takes 이, and 제일 does the "most" work.

If you missed Exercise 1 or 2, reread the mistakes section. The next section shows where to go from here.

Next Lessons and Where to Go from Here

The next lesson to read beside this one is the comparison particle 보다, which covers the standard in depth. If the previous lesson in this set felt shaky, return to 만 vs 밖에. For likeness instead of more or less, read the 처럼 like particle.

What this lesson does not cover. This lesson does not cover the verb ending -(으)ㄹ수록 (the more, the more), the equal comparison with 만큼 beyond a short mention, or adjectives in clauses with -(으)ㄴ. Every lesson in this particle set is listed on korean comparison particles.

In short, Korean comparatives and superlatives 더 가장 work by placing an adverb before an unchanged adjective: use 더 for two items, use 가장 or 제일 for three or more, name the standard with 보다, and name the group with 에서 or 중에서.

Frequently Asked Questions

What do 더 and 가장 mean? 더 means "more" and makes a comparison between two things: 이 가방이 더 비싸요 (this bag is more expensive). 가장 means "most" and picks the top item from a group of three or more: 서울은 한국에서 가장 큰 도시예요 (Seoul is the biggest city in Korea). 제일 has the same meaning as 가장 and is common in speech.

How do I form a comparative in Korean? Put 더 before the adjective or adverb and leave the adjective unchanged: 크다 becomes 더 커요, and 빠르다 becomes 더 빨라요. Add 보다 after the thing you compare with: 이 가방이 저 가방보다 더 비싸요. Korean has no ending like the English -er, so 비싸더요 is wrong; write 더 비싸요.

What is the most common mistake with 더 and 가장? Learners add an English-style ending, as in 비싸더요, or use 보다 on the wrong noun. The noun with 보다 is the standard, the one you compare against. In 이 가방이 저 가방보다 더 비싸요, the bag that is more expensive takes 이, and the bag that is the standard takes 보다.

How is 더/가장 different from similar forms? 더 and 가장 are adverbs of degree that sit before the predicate. 보다 is a particle that follows the noun you compare against, and it means "than". 중에서 is a particle phrase that names the group for a superlative, "among". A full sentence often uses all of them: 과일 중에서 사과가 제일 좋아요.

Do I use 더/가장 in speech, writing or both? Both. 더 appears everywhere, in speech and writing. 가장 is neutral and common in writing, reports and careful speech. 제일 is more spoken, but it is also fine in writing. A written alternative for 더 is 더욱, and a very common intensifier is 훨씬 더 (much more). None of these change with politeness.
