Banmal vs Jondaemal: How to Tell Korean Speech Levels Apart

존댓말 and 반말 are the two labels Korean speakers use to sort speech into levels, and almost all the information sits in the last syllable of the sentence. 먹었어 and 먹었어요 are the same verb, the same tense, the same meaning — one syllable apart, and on opposite sides of the line. This is a map of that line: which endings belong to which label, what the sub-style names mean, and how to hear the switch in dramas and song lyrics.

What the two labels actually name

존댓말 is the cover term for speech whose endings carry a politeness marker. 반말 is the cover term for speech whose endings do not. Korean grammar books split them further into named styles: 해요체 and 합니다체 sit on the 존댓말 side, 해체 (the technical name for everyday 반말) and 해라체 on the other.

A useful detail: the labels describe endings, not vocabulary. Whether a sentence counts as 존댓말 does not depend on how formal the words are — 밥 먹었어요 is 존댓말 and 식사하셨어 is not, even though the second sentence contains a far more elevated verb.

The endings that mark 존댓말

Two ending sets do the work. The first is 요, attached to the plain form: 가요, 먹었어요, 예뻐요, 어디예요. The second is the 합니다 set: 갑니다, 먹었습니다, 좋습니다, questions in -습니까. News anchors, flight announcements and military dialogue in dramas run almost entirely on that second set.

A third signal lives inside the verb rather than at the end. The infix -으시- raises the subject of the sentence, producing 가세요 from 가요 and 오십니다 from 옵니다. It combines with either ending set, which is why a single sentence can carry two separate politeness markers at once.

The endings that mark 반말

The plain side is the same verb stem with the marker stripped off. Statements end in a bare -어/-아 (먹어, 갔어, 좋아) or in -야 after a noun (학생이야). -지 turns up in 그렇지 and 맞지. Questions arrive as -어? with rising intonation, or as -니 and -냐 (어디 가니?, 밥 먹었냐?). Commands drop to -어라 or a bare -어 (빨리 와), and suggestions to -자 (같이 가자).

There is also a written branch: 해라체, the style used in books, newspapers and diaries, ending in -는다/-다 (간다, 먹는다, 좋다). It is plain in form but neutral in feel, because writing has no listener to address.

Hearing the line in dramas and lyrics

Screen dialogue is full of the moment where a character crosses from one side to the other, and Korean audiences catch it instantly: 어디 가세요 becomes 어디 가, or 왜 그러세요 becomes 왜 그래. Nothing else in the sentence moves. Song lyrics sit mostly on the plain side, which is why a chorus like 보고 싶어 has no 요 — and why the polite equivalent 보고 싶어요 shows up when a singer addresses the audience between songs rather than inside the song.

Two forms are worth flagging because they blur the outline. 요 can be tacked onto almost any fragment (아니요, 저요?), which makes short answers hard to classify at a glance. And 존댓말 with -으시- can appear alongside 반말 endings inside one exchange when a speaker is quoting someone else. Working through the Korean grammar overview and the 해요체 lesson makes the endings easier to spot at speed, and the formal 합니다체 set follows the same logic one step up. Since address terms shift on the same axis, the oppa and hyung map is the companion piece to this one.
