Almost every learner meets Korean politeness as one ladder: 합니다 at the top, 해요 in the middle, 해 at the bottom. Pick a rung and stay on it.
That model is wrong, and it breaks the first time you talk to a friend about your teacher.
1 · The two dials
| Dial | Raises | Shown by |
|---|---|---|
| Listener | The person you are talking **to** | The sentence ending: 합니다 · 해요 · 해 |
| Subject | The person you are talking **about** | -(으)시- inside the verb, and honorific nouns |
| Korean | To whom | About whom |
|---|---|---|
| 선생님이 가셨습니다 | Someone senior | The teacher — raised |
| 선생님이 가셨어요 | A polite everyday listener | The teacher — raised |
| 선생님이 가셨어 | A close friend | The teacher — raised |
| 친구가 갔어 | A close friend | A friend — not raised |
2 · Why learners collapse them
Because in the commonest case they move together. When you speak politely to your teacher about your teacher, both dials are up and you never see the seam.
The seam only shows in two situations, and both are everyday: talking casually about someone senior, and talking politely about someone junior.
| Situation | Listener | Subject |
|---|---|---|
| Telling a friend that your boss left | Down (반말) | Up (-시-) |
| Telling your boss that a junior colleague left | Up (합니다체) | Down (no -시-) |
| Telling a friend that another friend left | Down | Down |
| Telling your boss that the director left | Up | Up |
