The basic Korean Adjectives
If you’re starting to learn Korean, you’ll quickly encounter Korean adjectives. Describing things is, after all, a fundamental part of any language! While Korean grammar can seem daunting at first, the basic structure of Korean adjectives is actually quite straightforward.
One of the most noticeable features is that *almost all* Korean adjectives, in their dictionary form, end with the syllable -다 (-da). Think of it as their “default” ending.
Let’s look at some Korean adjectives list:
예쁘다 (ye-ppeu-da): pretty, beautiful
크다 (keu-da): big, large
작다 (jak-da): small
좋다 (jo-ta): good
나쁘다 (na-ppeu-da): bad
맛있다 (ma-sit-ta): delicious
비싸다 (bi-ssa-da): expensive
See the pattern? Every single one ends in -다!
Why ‘-da’?
The ‘-da’ ending indicates the declarative form of the Korean adjectives. It’s how the Korean adjectives are listed in the dictionary and how you’ll often see it in simple statements, or when just stating a fact. It essentially signifies the Korean adjectives are that quality.
Important Note: You usually don’t use the ‘-da’ ending when you’re actively using the adjective to describe a noun or within a sentence. You’ll need to conjugate the adjective based on the level of politeness and the grammatical structure of the sentence. In these cases, the -다 will be dropped and the stem will be modified.
Types of Korean Adjectives
Korean adjectives can be classified into two primary categories: descriptive adjectives and an adjective form of verbs called stative verbs.
Descriptive adjectives directly express a quality. For example, the adjective “예쁘다” (yeppeuda) means “to be pretty,” and when used in a sentence, it modifies the noun it describes.
Story Style Breakdown™ (Example Sentence)
Let’s break down the first sentence using our Story Style Breakdown™ so you can really understand it:
Original Korean Sentence
꽃이 예쁘다.
Pronunciation Guide
꼬치 (ggo-chi) 예쁘다 (ye-bbeu-da).
Meaning and Context
꽃 (flower) 이 (I’m going to talk about the flowers) 예쁘 (to be pretty/beautiful) 다 (are; I’m expressing my opinion).
Grammar
* 이/가: Subject marker used with a noun. “이” is used after words ending in a consonant, and “가” is used after words ending in a vowel.
English Translation
The flowers are pretty.
Literal Translation
Flowers are pretty.
In contrast, stative verbs, such as “좋다” (jota), meaning “to be good,” can function similarly to Korean adjectives when used in a context that describes a state of being.
Original Korean Sentence
날씨가 좋다.
Pronunciation Guide
날씨가 (nal-ssi-ga) 조타 (jo-ta).
Meaning and Context
날씨 (weather) 가 (subject particle; used with words ending in vowels) 좋 (to be good) 다 (is; I’m expressing my opinion).
English Translation
The weather is good.
Literal Translation
Weather is good.
Korean adjectives work differently
Korean adjectives work differently from English adjectives. In English, adjectives stay the same regardless of how they are used in a sentence (e.g., “big” stays “big”). However, Korean adjectives function like verbs—they conjugate based on tense and politeness level.
Korean Adjectives Before Nouns
Korean Adjectives always end in “-다” (-da). This is their basic, or dictionary form. Think of it like the “to be” form in English, like “to be big,” “to be small,” or “to be pretty.”
However, when you want to use Korean adjectives *directly before* a noun (a person, place, or thing), you need to change them a little bit. This change is important to make the sentence grammatically correct and natural-sounding.
Let’s break it down with the examples:
크다 (keu-da): to be big
* This is the dictionary form.
* When you want to say “big house,” you change “크다” (*keu-da*) to “큰” (*keun*).
* So, big house is 큰 집 (keun jip). Notice the “-다” disappears and is replaced with “-ㄴ”. The “-ㄴ” is placed at the bottom of the preceding syllable as a final consonant (batchim).
작다 (jak-da): to be small
* This is the dictionary form.
* When you want to say “small bag,” you change “작다” (*jak-da*) to “작은” (*jageun*).
* So, small bag is 작은 가방 (jageun gabang). Similarly to the example above, the “-다” disappears and is replaced with “-은”. The “-은” is placed at the bottom of the preceding syllable as a final consonant (batchim).
예쁘다 (ye-ppeu-da): to be pretty
* This is the dictionary form.
* When you want to say “pretty flower,” you change “예쁘다” (*ye-ppeu-da*) to “예쁜” (*ye-ppeun*).
* So, pretty flower is 예쁜 꽃 (ye-ppeun kkot). Again, the “-다” disappears and is replaced with “-ㄴ”. The “-ㄴ” is placed at the bottom of the preceding syllable as a final consonant (batchim).
Why does this happen?
Essentially, it’s a grammar rule in Korean. These adjectives are being used to *modify* the noun, so they take a special form. The specific ending depends on whether the adjective stem (the part before the “-다”) ends in a vowel or a consonant.
Adjectives ending in a vowel: In the examples above, “크다” and “예쁘다” originally end in a vowel, so “-ㄴ” is attached to the original form to modify the noun.
Adjectives ending in a consonant: In the example above, “작다” originally ends in a consonant, so “-은” is attached to the original form to modify the noun.
Key takeaway: Don’t be confused by the dictionary form ending in “-다.” When an adjective comes before a noun, remember to change it by either adding “-ㄴ” or “-은”! You’ll learn which one to use with practice.
Conjugating Common Korean Adjectives
Korean adjectives work like verbs—they must be conjugated based on tense and politeness level. Let’s break down how to conjugate them in different tenses.
Present Tense (현재형)
In present tense, Korean adjectives don’t need an extra verb like “to be.” Instead, you drop -다 and add -아/어/여요 depending on the vowel in the stem.
Original Korean Sentence

Pronunciation Guide
가방이 (ga-bang-i) 자가요 (ja-ga-yo).
