Negative Questions as Tags: 안 …아요? / -지 않아요?

When an English speaker sees 안 추워요? or 춥지 않아요?, the instinct is to read a plain information request: "Is it not cold?" But most negative questions in Korean are not really asking for unknown information at all. Like English "It's cold, isn't it?", they are softened assertions — the speaker already has an opinion or an assumption and is inviting you to agree with it. Understanding this is what turns a stiff, literal reading into natural Korean, and it explains why the answers to these questions hinge on agreement rather than fact (covered on the companion page, answering a negative question).

Two shapes, one function

Korean forms a negative question in two ways, and both can be pronounced with the rising intonation of any 해요체 yes/no question:

• Short negation: 안 + verb/adjective + -아/어요? → 안 추워요? "isn't it cold?"
• Long negation: stem + -지 않아요? → 춥지 않아요? "isn't it cold?"

Grammatically they are questions; functionally they are usually hedged claims. This is one of Korean's central politeness moves: instead of asserting an opinion flat-out ("It's cold"), you float it as a negative question and let the listener confirm it, which feels gentler and more collaborative.

Opinion-seeking: nudging the listener to agree

The most common use is to put an opinion on the table without imposing it. The speaker plainly thinks the thing is true and wants a "yes, it is."

Notice how odd a flat assertion would feel by comparison: saying 경치가 아름다워요 states your verdict, while 경치가 아름답지 않아요? hands the verdict to the other person to ratify. That is the whole point of the construction.

Soft assumption-checking

The other everyday use is to gently check something you already suspect about the listener — their state, their situation, their plans — rather than interrogate them.

These are warm, face-saving openings. 오늘 안 바빠요? is a much softer way to angle toward an invitation than the blunt 오늘 시간 있어요?, because a negative question presupposes a favourable answer and lets the listener decline without friction.

The copula tag: 아니에요?

When the predicate is a noun, the negative question uses the copula's negative 아니에요? ("isn't it…?"), not 안. This is the tag you use to double-check an identification.

Crucially, 안 cannot negate a noun. You never say ×저 사람 안 학생이에요?; the copula carries its own negation as 아니에요. (For the underlying split, see 안 vs -지 않다.)

Short vs long: a difference of warmth

Both shapes are correct and interchangeable in meaning, but they carry slightly different colour. The short 안 …아요? is flatter and more neutral — a quick check. The long -지 않아요? tends to sound warmer, more deliberate, and more openly rhetorical, which is why it dominates when you are actively trying to bring the listener around to your opinion.

When it really is a question

The tag reading is the default, not a straitjacket. With the right context and a more neutral, genuinely inquiring intonation, a negative question can be a real information request — you actually don't know, and you want to find out. The negative framing then just adds a shade of expectation or mild surprise, much like English "Hasn't he arrived yet?"

So the construction spans a spectrum: from a pure agreement-seeking tag (경치가 아름답지 않아요?) to a genuine, expectation-laden question (안 왔어요?). Intonation and context place any given utterance on that line. What stays constant is how you answer it — by agreement, not by English polarity.

A note on answering them

Because these are agreement-seekers, their replies follow the proposition-confirming logic of 네/아니요: if you agree with the negative claim, you say 네 and repeat the negative; if you disagree, you say 아니요 and give the positive fact.

The full treatment — and the flip relative to English — lives on answering a negative question.

Common Mistakes

1. Reading the tag as a neutral question and mis-answering it. Because you took 안 바빠요? as a literal "Are you not busy?", you answer with English polarity and confirm the wrong thing.

2. Negating a noun with 안. A noun predicate takes the copula negative 아니에요?, never 안 before the noun.

3. Doubling up short and long negation. Pick one shape. Stacking 안 and -지 않다 on the same predicate is ungrammatical.

4. Using the flat 안 …아요? where the persuasive -지 않아요? fits. Grammatical, but the wrong tool for gently pushing an opinion.

Key Takeaways

• A Korean negative question has two shapes — short 안 …아요? and long -지 않아요? — and both usually work as softened assertions / agreement-seeking tags, not neutral yes/no requests.
• The construction is Korean's main device for floating an opinion (경치가 아름답지 않아요?) or gently checking an assumption (오늘 안 바빠요?) without asserting it outright.
• Noun predicates tag with the copula negative 아니에요?; 안 never negates a noun.
• -지 않아요? reads warmer and more rhetorical; 안 …아요? is flatter and quicker. Match the shape to your intent.
• Answer these as agreement-checks: 네 confirms the negative claim, 아니요 corrects it — the reason answering a negative question needs its own page.
