Understanding Korean Politeness Levels (반말 vs 존댓말)

Why Korean has 3+ ways to say every sentence, and how to pick the right one without offending anyone.

Why Politeness Levels Exist

Korean encodes social relationships directly into the language. Every sentence you speak reveals how you perceive your relationship with the listener — their age, social status, and how close you are. This isn't optional decoration; using the wrong level can genuinely offend someone. The good news: modern Korean has simplified to three main levels that cover 99% of situations.

When in doubt, use 해요체 (polite). It's safe in almost every situation and won't offend anyone.

Level 1: 반말 (Casual) — Among Friends

반말 (banmal, literally 'half-speech') is the informal level used between close friends of similar age, with younger people, or with children. Verb endings: -아/어 (해, 가, 먹어). Using 반말 with someone older or a stranger is considered rude. Only use it when someone explicitly says '말 놓으세요' (please speak casually) or you're clearly close friends.

반말 rule of thumb: only use it if THEY use it with you first, or you've agreed to speak casually.

Level 2: 해요체 (Polite) — The Default

해요체 (haeyo-che) is the standard polite level for everyday conversation. Verb endings: -아요/어요 (해요, 가요, 먹어요). Use it with strangers, acquaintances, colleagues, people slightly older, and anyone you want to be polite to. This is your safe default — start here and adjust only when you're sure of the relationship.

해요체 is versatile because it's polite without being stiff. You can use it with your boss AND your slightly-older neighbor.

Level 3: 합쇼체 (Formal) — Maximum Respect

합쇼체 (hapsyo-che) is the highest formality level. Verb endings: -ㅂ니다/습니다 (합니다, 갑니다, 먹습니다). Used in news broadcasts, formal presentations, military, customer service, and with much older people. It sounds professional and respectful but can feel cold or distant in casual settings.

합쇼체 is what you hear in Korean news, at job interviews, and in formal speeches. It's respected but creates emotional distance.

Same Verb, Three Moods

Let's see '먹다' (to eat) in all three levels. 반말: 먹어 (meogeo) — eating! 해요체: 먹어요 (meogeoyo) — I eat / eating. 합쇼체: 먹습니다 (meokseumnida) — I eat (formal). Notice how 먹어→먹어요 just adds 요, but 먹습니다 is a completely different ending. The conjugation rules for 합쇼체 depend on whether the verb stem ends in a consonant or vowel.
