Dropping Subjects and Objects (Pro-Drop)

Here is a sentence a Korean speaker says a dozen times a day: 밥 먹었어요? It means "Did you eat?" — but look closely and there is no word for "you" anywhere in it. There is no word for "I" in the answer either. Korean freely drops any argument the listener can recover from context, and it does so far more aggressively than English ever allows. This page establishes the phenomenon; learning to leave things out is as important as learning to put them in, because a sentence stuffed with pronouns is the clearest fingerprint of English hiding underneath.

English fills every slot; Korean fills only what's needed

English grammar forces you to name a subject in every finite clause. You cannot say "Am eating" — you must say "I am eating." You cannot even describe the weather without inventing a subject that refers to nothing: "It is raining." That dummy "it" is grammatically required and semantically empty. Korean has no such rule. If who or what you mean is obvious, you simply don't say it.

In that little exchange, both the subject (you / I) and, in the reply, the object (the meal) simply evaporate. Nobody is being vague or lazy — the context has already supplied everything, so restating it would be over-explaining, the way an English speaker who answered "Did you eat?" with "Yes, I ate a meal of food today" would sound strangely heavy.

Questions and answers drop the obvious person

The most common place pronouns disappear is in ordinary back-and-forth, where "you" (the person you're talking to) and "I" (yourself) are never in doubt.

Neither sentence names a person. 어디 가요? cannot mean anything but "where are you going?" — you're asking the person in front of you. 집에 가요 cannot mean anything but "I'm going home" — you're the one answering. Adding 당신은 ("you") to the question or 저는 ("I") to the answer would not make them clearer; it would make them sound stilted, textbook-ish, or subtly confrontational.

A bare adjective is a complete sentence

Because the subject can vanish entirely, a single predicate word can stand as a whole grammatical sentence. If a friend hands you a coffee and you sip it, you can express "I like it" with one word — the verb of liking, with nothing in front of it.

What "좋아요" means depends entirely on the situation — "I like it," "it's fine," "sounds good," "sure." That is exactly the point: Korean lets context do the work that English forces onto an explicit subject.

Weather has no dummy subject

English weather sentences are the purest illustration of the difference, because English invents a subject ("it") that points to nothing at all. Korean uses the actual event as its subject and adds no dummy word.

Notice 비가 와요: "rain" (비) is the genuine subject — it is the thing coming — so it takes the subject particle 가. There is no slot for, and no need for, an English-style "it." When you catch yourself reaching for a word to translate the "it" in "it's raining," stop: that word does not exist in Korean.

Objects drop just as freely

Pro-drop is not limited to subjects. Once a thing has been mentioned, it, too, disappears on the next reference — where English would keep saying "it."

The answer 봤어요 carries no object at all, yet nobody wonders seen what? — the movie is right there in the shared context. English is obliged to pin it down with "it"; Korean simply trusts the conversation.

Overt pronouns are heavy, and sometimes pointed

Korean does have pronouns — 저/나 ("I"), 너 ("you"), 그 사람 ("that person") — but they are used sparingly and carry weight. Bringing in an overt pronoun where context already covers it can sound emphatic, contrastive, blunt, or oddly formal. 저는 학생이에요 is perfectly fine when you're genuinely introducing yourself, because "I" is new information there. But firing a 저는 or 그것을 into every sentence, the way English fires "I" and "it," is the single most reliable tell of a sentence built in English and then swapped word-for-word into Korean.

The reframe: overusing pronouns doesn't make you clearer in Korean; it makes you sound like a translation. Aim to name a referent only when it is genuinely new, genuinely contrastive, or genuinely ambiguous — and otherwise let it drop. The finer machinery of how far back a dropped referent can reach, and what happens when two candidates compete, is handled on the context recovery page; here the lesson is simply that the empty slot is normal and expected.

Common Mistakes

Mistake 1 — Inserting 당신 for "you." English speakers reach for 당신 as the default word for "you," but 당신 is marked and distant — it shows up in ads, in song lyrics, in translated text, or in a married couple's arguments. To an ordinary listener it feels cold or pointed. Use the person's name or title, or drop it entirely.

Mistake 2 — Putting a subject pronoun in every clause. English needs a subject in each finite clause, so learners repeat 저는 relentlessly. In Korean, name yourself once (if at all) and drop it thereafter.

Mistake 3 — Inventing a dummy subject for the weather. There is no Korean "it." Do not translate it.

Mistake 4 — Keeping "it" as an overt object. Once the thing is known, the object slot goes empty; don't fill it with 그것을.

Key Takeaways

• Korean drops any argument — subject or object — that context already makes clear; the empty slot is the default, not an omission.
• Everyday questions and answers name neither "you" nor "I"; 어디 가요? / 집에 가요 is complete.
• Weather takes the real event as subject (비가 와요) and has no dummy "it."
• Overt pronouns are heavy and used sparingly; 당신 is distant, and repeating 저는/그것을 in every clause is the top sign of English transfer.
