Korean Comparatives and Superlatives: 더, 제일, 가장 Explained

Learn how to compare things in Korean using 더 (more), 제일 and 가장 (most), and the -보다 particle, with clear tables and example sentences.

Comparing two things or picking "the best" is a basic conversational need, and Korean handles it with a small set of words that are easy to learn but easy to mix up at first: 더, 보다, 제일, and 가장.

Making Comparisons with 더 (More) and -보다 (Than)

To compare two things, attach -보다 ("than") to the thing being compared against, and add 더 ("more") before the adjective.

Pattern	Example	Meaning
A가 B보다 더 [adjective]	이게 저거보다 더 비싸요.	This is more expensive than that.
A가 B보다 덜 [adjective]	오늘이 어제보다 덜 추워요.	Today is less cold than yesterday.

The order of A와 B와 -보다 is flexible in Korean — 저거보다 이게 더 비싸요 means the same thing, just with a different emphasis.

Superlatives with 제일 and 가장

Both 제일 and 가장 mean "the most," and they are interchangeable in nearly all everyday contexts — 가장 is slightly more formal/written, while 제일 is more common in speech.

Korean	Example	Meaning
제일	이게 제일 맛있어요.	This is the most delicious.
가장	이것이 가장 중요합니다.	This is the most important.

Adding a Comparison Group

To specify "the most among X," attach 중에서 ("among") to the group being compared.

• 한국 음식 중에서 김치찌개가 제일 좋아요. — Among Korean foods, kimchi jjigae is my favorite.
• 우리 반에서 그 학생이 가장 똑똑해요. — Among our class, that student is the smartest.

Common Mistakes to Avoid

1. Forgetting -보다 in comparisons. Without it, the sentence loses its comparative meaning entirely — "이게 더 비싸요" alone just means "this is more expensive" with no clear reference point.
2. Using 더 with superlatives. 더 is only for comparing two things; for "the most," use 제일 or 가장 instead, never both together.
3. Word order confusion. Since Korean word order is flexible, beginners sometimes place -보다 incorrectly — it always attaches directly to the noun being compared against, never to the adjective.

Quick FAQ

Is there a difference between 제일 and 가장 in meaning? No real difference in meaning — the choice is mostly about formality and personal style, similar to choosing "kind of" versus "somewhat" in English.

How do I say "the same as"? Use -와/과 같다 or 처럼: 이것은 저것과 같아요 (This is the same as that).

Comparisons come up constantly in daily conversation — shopping, describing food, giving opinions. Klovers' conversation practice builds these patterns into real, natural-sounding sentences from day one.
