×커피를 좋다: 을/를 with 좋다, 싫다, 있다

You want to say "I like coffee." Coffee is the object of like in English, so you mark it as an object: ×저는 커피를 좋아요. Every English speaker builds this sentence, and it's wrong. The correct version is 저는 커피가 좋아요 — coffee takes the subject particle 이/가. The reason is one of the deepest structural facts about Korean: a whole family of "feeling" words that English treats as transitive verbs are, in Korean, descriptive verbs (adjectives) whose stimulus is the grammatical subject. An adjective has no object to mark, so 을/를 simply has no slot there.

Why the English brain does this

In English, like, need, fear, want, have are transitive verbs: I like X, I need X, I fear X — X is a direct object. So the learner reaches for the direct-object particle 을/를 (을 after a batchim, 를 after a vowel) and attaches it to the thing liked, needed, or feared.

But Korean doesn't build these as "I do something to X." It builds them as "X is pleasing / is needed / is scary [to me]." The Korean word is an adjective — and Korean adjectives are a kind of verb — describing a quality of the thing, not an action aimed at it. So the thing is the subject (이/가), and the experiencer becomes the topic:

That structure — 저는 (experiencer/topic) + 커피가 (grammatical subject) + adjective — has two nominative-flavored slots and no object at all. It's the signature shape of Korean feeling-predicates.

The pattern across the family

The same trap is set by every psych-adjective and the existence verbs. Learn the shape once and it generalizes.

Notice 있다/없다 ("have/exist") belong here too: Korean says "time exists to me," so what you have is the subject, never an object. ×시간을 없어요 is impossible.

The escape hatch: the -하다 verbs DO take 을/를

Here's the part that rescues your English instinct. For most of these adjectives, Korean has a matching action verb ending in -하다, and that one is genuinely transitive — it takes 을/를 exactly the way English expects. 좋다 (adjective, "is pleasing") pairs with 좋아하다 (verb, "to like"):

So both 커피가 좋아요 and 커피를 좋아해요 are correct — they just use different words. There's a nuance worth knowing: the bare adjective 좋다 reports your own inner feeling (subjective, most natural in the first person), while 좋아하다 reports an observed preference and sits more comfortably describing other people — which is why "my sibling likes soccer" prefers 좋아하다. The full contrast lives on the 좋다 vs 좋아하다 page.

Common Mistakes

One reflex generates all of these: marking the stimulus with 을/를 because the English verb is transitive. When you catch yourself doing it, either switch the particle to 이/가 (keep the adjective) or switch the verb to the -하다 form (keep the object) — both fix it.

1. ×커피를 좋다. 좋다 is an adjective; its stimulus is the subject.

2. ×돈을 필요하다. 필요하다 means "is necessary," so money is what's needed → subject.

3. ×뱀을 무섭다. 무섭다 means "is scary."

4. ×시간을 있다. 있다 is "exists," never a transitive "have."

Key Takeaways

• Korean encodes like/dislike/need/fear/have as descriptive verbs (adjectives) — "X is pleasing/needed/scary/existent" — so the stimulus is the subject (이/가), not an object.
• The structure is experiencer(는) + stimulus(이/가) + adjective: 저는 커피가 좋아요. There is no object slot for 을/를.
• The matching -하다 action verbs (좋아하다, 싫어하다, 무서워하다) are transitive and take 을/를: 커피를 좋아해요.
• 있다/없다 belong to the adjective camp: 시간이 있어요, never ×시간을 있어요.
• Fix on the fly: either swap the particle to 이/가 (keep the adjective) or swap the verb to -하다 (keep 을/를).
