Soft Wondering: -나요? / -(으)ㄴ가요?

Korean lets you dial a question's force up or down purely by choosing a different ending. A bare -아/어요? question (자리 있어요? "Is there a seat?") is direct — it puts the listener on the spot to answer. Swap in -나요? or -(으)ㄴ가요? and the same question softens into "I was just wondering whether there might be a seat…". These are the endings of polite service counters, online Q&A boards, and any moment where you want to sound curious and considerate rather than demanding. This page shows you which one to use, and why the choice splits along the verb-vs-adjective line that runs through all of Korean grammar.

What these endings do

English needs extra words to soften a question — "Would it happen to be…?", "I was wondering whether…", "Do you know if…". Korean folds that softening into the verb ending itself. -나요? and -(으)ㄴ가요? both add a note of gentle, non-pushy curiosity. They present the question as something you're musing about, leaving the listener room to answer at ease.

Compare 자리 있어요? ("Is there a seat?") — perfectly polite, but blunter and more transactional. 있나요? adds deference and a touch of hesitancy, exactly the way a customer speaks to staff or a newcomer asks a room full of strangers.

The split: verbs take -나요?, adjectives take -(으)ㄴ가요?

Here is the one rule that governs everything below. In the present tense, the two endings divide the predicate world in half along the same fault line that splits Korean grammar everywhere:

• Action verbs and the existence pair 있다 / 없다 take -나요?
• Descriptive verbs (adjectives) and the copula 이다 take -(으)ㄴ가요?

Verbs and 있다/없다 → -나요?

Attach -나요? straight onto the plain stem — no vowel adjustment, whether the stem ends in a vowel or a consonant.

Notice the pronunciation shifts that RR reflects: 먹나요 is read [멍나요] (meongnayo) — the ㄱ before ㄴ nasalizes to [ŋ]. 있나요 is [인나요] (innayo) and 맞나요 is [만나요] (mannayo), the batchim neutralizing and then nasalizing before ㄴ. This nasalization is automatic and applies every time -나요 lands on a consonant-final stem.

Adjectives and 이다 → -(으)ㄴ가요?

Descriptive verbs use -(으)ㄴ가요?, whose shape depends on the stem's final sound:

• After a batchim (consonant): -은가요? — 좋다 → 좋은가요?, 많다 → 많은가요?
• After a vowel: -ㄴ가요? — 예쁘다 → 예쁜가요?, 바쁘다 → 바쁜가요?
• The copula 이다 takes -인가요? — 학생 → 학생인가요?

The past tense collapses the split

Here is the elegant payoff. In the past tense, both classes converge on -았/었나요? — the -(으)ㄴ가요? form simply disappears. The reason is mechanical: a past stem always ends in 았/었, i.e. in the consonant ㅆ, and a consonant-final stem takes -나요?. So verbs and adjectives alike ride the same ending once you're talking about the past.

You never say ×어려웠은가요 or ×바빴은가요. The present-tense choice between -나요 and -(으)ㄴ가요 matters only in the present; the past neutralizes it. This is one of those rare places where Korean grammar gives you less to memorize as you go up a tense.

How soft is it, really?

The gap between 있어요? and 있나요? is small but real, and native speakers feel it. A blunt -아요? question treats the answer as owed to you; -나요? treats it as a favor you're hoping for. That's why -나요? dominates situations with a built-in power or familiarity gap — a customer to a clerk, a newcomer to a group, a citizen to an official. It buys you softness without the stiffness of the fully formal -습니까?.

The second example stacks the softener 혹시 ("by any chance") with the honorific -시- and -나요? — a triple hedge that sounds delicate and considerate, the register of someone treading carefully around a possibly awkward question.

The modal cousin: -(으)ㄹ까(요)?

Don't confuse -(으)ㄴ가요? with the "shall we / I wonder" ending -(으)ㄹ까요?. The 까 form projects into an unrealized event — a suggestion (같이 갈까요? "Shall we go together?") or a guess about something not yet known (비가 올까요? "Do you think it'll rain?"). The -(으)ㄴ가요? form asks about a present fact you simply don't have. Full treatment lives on the -(으)ㄹ까요? page.

Register and tone

-나요? and -(으)ㄴ가요? are polite (they carry 요) and lean gentle. They are extremely common in:

• Service and customer speech — a shopper asking staff, a patient asking a pharmacist.
• Online Q&A and forums — 이거 맞나요? / 배송 언제 오나요? headline thousands of posts, because they read as humble and non-confrontational.
• Softened requests and checks — where a bare -아요? would feel abrupt.

Because the tone is inherently soft, over-relying on them with someone you're close to can sound oddly formal or distant. Among friends you'd drop back to plain -아? / -지? or the plain-style -니?/-냐? endings.

Common Mistakes

1. Putting adjectives on -나요? (the core error). In standard Korean, descriptive verbs take -(으)ㄴ가요?, not -나요?.

2. Putting the copula 이다 on -나요?. The copula patterns with adjectives → -인가요?.

3. Keeping -(으)ㄴ가요? in the past tense. Once you go past, both classes use -았/었나요?.

4. Adding an extra 이 before the vowel-stem -ㄴ가요. After a vowel-final adjective stem, the ending is bare -ㄴ가요, not -은가요.

Key Takeaways

• -나요? and -(으)ㄴ가요? soften a question into gentle "I wonder if…" territory — considerate, deferential, non-pushy.
• Present tense splits by predicate: verbs and 있다/없다 → -나요?; adjectives and 이다 → -(으)ㄴ가요? (-은가요 after batchim, -ㄴ가요 after a vowel, -인가요 for the copula).
• Past tense converges: everything becomes -았/었나요?, and the -(으)ㄴ가요? form vanishes.
• Don't confuse -(으)ㄴ가요? (asking a present fact) with the modal -(으)ㄹ까요? (suggestion / guess about an unrealized event).
• Standard Korean keeps adjectives off -나요?; the colloquial 예쁘나요? exists but isn't the model to learn from.
