Korean Speech Levels — Formal vs Informal Korean Explained
Why Speech Levels Exist in Korean
Korean embeds social hierarchy directly into its grammar. The speech level you choose signals your relationship to the listener — their age, status, familiarity, and the formality of the situation. This is not merely polite vocabulary swapped in and out; the verb endings themselves change completely depending on the level. In English, you might say 'please pass the salt' or 'pass the salt, would you?' — the meaning is the same and only the phrasing softens. In Korean, a waiter, a close friend, and a company CEO would hear structurally different sentences with different verb forms, different particles, and sometimes different vocabulary altogether. Understanding speech levels is not optional for Korean communication — using the wrong level in the wrong context is perceived as either rude (if too casual) or robotic and cold (if overly formal). The system reflects Confucian values of hierarchical respect that are woven into Korean social and professional life.
The 3 Speech Levels That Actually Matter
Korean technically has seven speech levels, but three account for roughly 95% of modern usage. Formal polite (합쇼체, hapsyo-che): uses -습니다/-ㅂ니다 verb endings and -십시오 for commands. This is the level of news broadcasts, formal presentations, airline announcements, and job interviews. It signals professionalism and full respect. Informal polite (해요체, haeyo-che): uses -아요/-어요 endings. This is the workhorse level — everyday workplace conversation, service interactions, speaking to older acquaintances you are not close to, and polite interactions with strangers. It is warm but respectful. Casual/intimate (해체 or 반말, banmal): drops the polite endings entirely — 가 (go) instead of 가요 (go-polite). This level is used with close friends of equal or younger age, children, and in internal monologue or diary writing. Using 반말 with someone who did not invite it is considered quite rude in Korean social contexts.
How to Choose the Right Level
The decision framework is simpler than the full seven-level system suggests. Default rule: use informal polite (해요체) with everyone you do not know well. This level is universally appropriate and will not offend anyone. Upgrade to formal polite (합쇼체) for job interviews, formal speeches, meeting senior executives, or any high-stakes professional setting. Downgrade to casual (반말) only when a Korean friend or peer explicitly invites it — a common phrase is 말 놓아도 돼 (you can speak casually). Age and hierarchy determine who initiates the shift to banmal, not the foreigner. In ambiguous workplace situations, match the level your direct colleagues use with each other. When in doubt, stay at 해요체 — it signals effort and respect without being stiff, and native speakers consistently appreciate foreigners who use it well.
Common Mistakes Foreigners Make With Speech Levels
The most frequent mistake is treating 반말 as the 'real' Korean learned from dramas and songs — then using it with Korean adults you have just met. Dramas portray intimate relationships in which characters have already shifted to 반말; the shift itself is a meaningful social moment that happens over time. Starting with 반말 skips that moment and reads as socially unaware. A second common mistake is rigidly using formal polite (합쇼체) in casual settings like lunch with colleagues — it creates distance and formality that Korean coworkers may find alienating. A third mistake is mixing levels within the same sentence, which happens when learners know some -아요 endings and some -습니다 endings and alternate randomly. Each conversation should stay consistently at one level. The practical fix for all three mistakes: learn 해요체 thoroughly first, master it completely, then learn 합쇼체 for formal settings and 반말 for invited intimacy.
