있는 / 없는: The -는 Attributive of 있다 and 없다

To turn a predicate into something that modifies a noun — "a book that is on the desk," "a person who has no money" — Korean changes the ending on the predicate and puts the whole thing before the noun. There are no relative pronouns like English who or that; the verb itself inflects. For 있다 and 없다 that inflected form is 있는 and 없는, and the ending is the crucial detail: it's the verb-type -는, not the adjective-type -(으)ㄴ. Getting this right is the root rule behind a large family of everyday modifiers.

Existence modifiers take the verb ending -는

Korean modifying clauses (what English calls relative clauses) reverse English word order: the clause comes before the noun it describes, with no relative pronoun and no gap-filler. To build one in the present tense, action verbs and 있다/없다 take -는.

Note the pronunciation, since it isn't obvious from the spelling: the final consonant of 있 and 없 nasalizes before the ㄴ of -는, so 있는 is said [인는] (inneun) and 없는 is said [엄는] (eomneun). The spelling stays 있는 / 없는; only the sound shifts.

Why -는 and not -(으)ㄴ? The verb / adjective split

Korean sorts its present-tense modifiers by word class. This is the deep logic, and it pays off across the whole grammar:

• Action verbs and 있다 / 없다 take -는: 가는 사람 ("a person who goes"), 있는 사람 ("a person who is there / who has [it]").
• Adjectives (descriptive verbs) take -(으)ㄴ: 좋은 사람 ("a good person"), 예쁜 꽃 ("a pretty flower").

Remember that Korean adjectives are verbs — descriptive verbs — so both classes are verbs at heart, but they split on this ending (the full contrast lives on the -(으)ㄴ vs -는 attributive page). 있다 and 없다 pattern with the action verbs here, even though their meaning ("exist") feels stative and adjective-like. That mismatch — stative meaning, verb-type ending — is precisely why they're a classic trap.

Put those two side by side: 좋은 uses -(으)ㄴ because 좋다 is an adjective; 있는 uses -는 because 있다 is not. "Popular" in Korean is literally "has popularity" (인기가 있다), so it rides on 있다 and therefore takes -는.

This is the root rule behind 맛있는, 재미없는

The 있다/없다 compound adjectives — 맛있다, 재미있다, 멋있다, 재미없다 — inherit their attributive behavior directly from this rule. Because they end in 있다 or 없다, they take -는, giving 맛있는, 재미있는, 멋있는, 재미없는. This is why they behave differently from a "normal" adjective in attributive position, and it all traces back to the parent verbs.

If you learn 있는/없는 as the root form, you never have to memorize 맛있는 and 재미없는 separately — they're just the -있다/-없다 words obeying their parent's rule. (Their own page treats them in more detail: -있다 / -없다 compound attributives.)

Past attributive: 있던, 있었던, 없던

The present is firmly 있는/없는, but the past attributive uses the retrospective -던 (and its perfective cousin -었던): 있던 / 있었던 for "that was / used to be there," and 없던 for "that wasn't there."

Don't let the past forms confuse the present rule: for the plain present modifier, it is always 있는 / 없는.

Common Mistakes

1. Regularizing to ×있은 / ×없은. Treating 있다 like a normal adjective and giving it -(으)ㄴ is the number-one error. Existence verbs take -는.

2. The same slip on the compound adjectives. 맛있다 ends in 있다, so its modifier is 맛있는, never ×맛있은.

3. ×없은 for '없는'. Same rule, negative side.

4. Forgetting the nasalization when you read it aloud. The spelling is 있는, but it is pronounced [인는] (inneun), and 없는 is [엄는] (eomneun). Reading them as written ("it-neun," "eop-neun") sounds off.

Key Takeaways

• The present attributive of 있다 / 없다 is 있는 / 없는 — the verb ending -는, never -(으)ㄴ.
• This is because Korean sorts modifiers by class: adjectives take -(으)ㄴ (좋은), action verbs and 있다/없다 take -는. 있다/없다 side with the verbs despite their stative meaning.
• The rule is inherited by every -있다 / -없다 compound: 맛있는, 재미있는, 멋있는, 재미없는.
• Pronounce them with nasalization: 있는 → [인는], 없는 → [엄는].
• The past attributive is 있던 / 있었던 / 없던, but the present is always 있는 / 없는.
