응/어 vs 네/예: Casual vs Polite 'Yes'

You can betray your speech level before you reach the verb. In Korean, the little words for "yes," "no," and "hey" are not register-neutral the way English yes and no are — each one is tied to a tier, and the very first sound out of your mouth announces whether you are being polite or casual. Say 응 to your boss and you have already slipped, no matter how carefully you conjugate the rest of the sentence. These words feel like free vocabulary to English speakers, but they are really the smallest, most exposed pieces of the honorific system. Getting them to match the register you're already in is half the battle of sounding natural.

The two sets

Everything below sorts into two columns. The polite (존댓말) set goes with 해요체 and 합니다체; the casual (반말) set goes with 해체. You switch the whole column as a unit, along with the rest of your speech level.

Why does English feel so different here? Because English yes is genuinely register-flat — you say the identical "yes" to a toddler and to a judge, and politeness lives entirely in the words around it ("yes, Your Honor"). Korean has grammaticalized the tier, so the response word itself must carry it. There is no neutral "yes" to fall back on; you are forced to choose 네 or 응 every single time, and each choice is a small honorific commitment.

The polite set: 네 / 예 and 아니요

네 is the everyday polite "yes." 예 is the same "yes" one notch more formal and deferential — the version you hear in 합니다체, in the military, in customer service, and from anyone being especially respectful. Both are correct; 네 is by far the more common in ordinary polite talk.

The polite "no" is 아니요 (often written and said 아니오, and easily confused with the copula-based 아니에요, "it isn't"). In quick speech 아니요 covers both "no" and a polite "not at all."

The casual set: 응 / 어 and 아니

Drop to 반말 and "yes" becomes 응 or 어. 응 is the softer, rounder casual yes; 어 is flatter and quicker. The casual "no" is a bare 아니 — the same root as polite 아니요, just stripped of its 요.

Casual 어 pulls double duty beyond "yes." It's the go-to backchannel — the "uh-huh / yeah" you drop in to show you're listening — and, said with a jump in pitch, a surprised "oh!"

Getting someone's attention: 야 vs 저기요

The address words split the same way. To flag down a stranger politely, you use 저기요 ("excuse me") or, if you know the name, 이름 + 씨. To grab a close friend's attention, you use the blunt vocative 야 ("hey").

네 is not just "yes" — it's the all-purpose polite response particle

Here is the piece that reframes the whole page. 네 does far more than answer yes/no questions. Treat it as the general-purpose polite response particle, and its casual counterpart 응/어 covers the same range one tier down.

• "Here!" — answering a roll call or a name being called.
• "Pardon?" — said 네? with a sharp rising tone when you didn't catch something.
• "Okay / got it / you're welcome" — a neutral acknowledgment, not answering any question at all.
• A listening backchannel — a low, repeated 네, 네… that just signals "I'm following you."

In casual speech, 응 and 어 slot into every one of these roles — the acknowledgment 어, 알았어 ("yeah, got it"), the listening 응, 응…, the "huh?" of 어? — so you really are switching a matched pair of all-purpose particles, not just two words for "yes." For the backchannel role specifically — how Koreans pepper conversation with these listening tokens — see agreement backchannels.

Common Mistakes

1. Answering 응 to someone you're addressing in 존댓말. A casual yes under a polite verb is a tier mismatch that reads as over-familiar or careless.

2. Answering a close friend with a stiff 네. Toward someone you're on 반말 terms with, 네 sounds cold, distant, or sarcastic — as if you've suddenly put up a wall.

3. Using 야 on a stranger. 야 toward someone you don't know is aggressive — practically picking a fight. Use 저기요.

4. Confusing 네 and 예 as different answers. They're the same "yes"; 예 is just more formal. Neither means "no" — the polite "no" is 아니요.

5. Mishearing the polite "no" 아니요 as the copula 아니에요. 아니요 answers "no"; 아니에요 means "it is not (that)." They overlap in sound and often in effect, but 아니요 is the bare response word.

Key Takeaways

• "Yes / no / hey" are not register-neutral in Korean — each belongs to a tier, and you switch the whole set with your speech level: polite 네·예 / 아니요 / 저기요, casual 응·어 / 아니 / 야.
• 예 is 네 one notch more formal; both mean "yes." The polite "no" is 아니요, easily confused with the copula 아니에요.
• Casual 어 also serves as the "uh-huh" backchannel and, with a pitch jump, a surprised "oh!"
• 야 is warm among close friends but confrontational toward strangers — use 저기요 to flag down anyone you don't know.
• Treat 네 as the all-purpose polite response particle — "yes," "here!", "pardon?", "okay," and a listening backchannel — with 응/어 as its exact 반말 counterpart.
