Up to here every sentence has ended in 이다. This is the lesson that adds real verbs.
Korean verbs are cited in the dictionary as stem + 다 — 가다, 먹다, 하다. The 다 is never used as-is in speech; you strip it off and attach an ending. Which ending is the whole lesson.
Vocabulary: places
Used with the question 어디(에) 가요? — where are you going?
| 학교 / 대학교 | school / university | 도서관 (圖書館) | library |
| 회사 (會社) | company, office | 서점 (書店) | bookshop |
| 집 | house, home | 우체국 (郵遞局) | post office |
| 공원 (公園) | park | 공항 (空港) | airport |
| 식당 (食堂) | restaurant | 병원 (病院) | hospital, clinic |
| 시장 (市場) | market | 약국 (藥局) | pharmacy |
| 은행 (銀行) | bank | 백화점 (百貨店) | department store |
| 회의실 (會議室) | meeting room | 화장실 (化粧室) | toilet |
회의실 is pronounced [회이실]. The ㅢ in a non-initial syllable is routinely levelled to [이] — the same thing happens to 회의해요 [회이해요] below.
가: 어디(에) 가요? Where are you going?
나: 회사(에) 가요. I'm going to the office.
Casual polite: -아요 / -어요 / -해요
Three endings, and the choice is made by the last vowel in the stem.
| Ending | When | Examples |
|---|---|---|
| -아요 | Last stem vowel is ㅏ or ㅗ | 살다 → 살아요 · 가다 → 가요 · 보다 → 봐요 |
| -어요 | Last stem vowel is anything else | 먹다 → 먹어요 · 읽다 → 읽어요 · 마시다 → 마셔요 |
| -해요 | The verb is noun + 하다 | 일하다 → 일해요 · 공부하다 → 공부해요 |
Note that it is the vowel, not the last letter. 먹다’s stem is 먹, which ends in a consonant — but its vowel is ㅓ, so it takes -어요.
The contractions
Adding the ending often produces two vowels in a row, and Korean collapses them:
| Verb | Literally | Actually | |
|---|---|---|---|
| 가다 | to go | 가 + 아요 → 가아요 | 가요 |
| 자다 | to sleep | 자 + 아요 → 자아요 | 자요 |
| 오다 | to come | 오 + 아요 → 오아요 | 와요 |
| 보다 | to see, watch | 보 + 아요 → 보아요 | 봐요 |
| 살다 | to live | 살 + 아요 | 살아요 |
| 먹다 | to eat | 먹 + 어요 | 먹어요 [머거요] |
| 읽다 | to read | 읽 + 어요 | 읽어요 [일거요] |
| 마시다 | to drink | 마시 + 어요 → 마시어요 | 마셔요 |
Two patterns: identical vowels merge (가아요 → 가요), and different ones fuse into a compound vowel (오아요 → 와요, 마시어요 → 마셔요). Stems ending in a consonant have nothing to collapse, so 살아요 and 먹어요 stay long — and link, as always.
하다 verbs
하다 is to do, and it attaches to a noun to make a verb out of it. This is the most productive pattern in the language — a large share of Korean verbs are built this way, including every imported one.
| Noun | + 하다 | → | |
|---|---|---|---|
| 하다 | 해요 | to do | |
| 일 | 일하다 | 일해요 | to work |
| 운동 | 운동하다 | 운동해요 | to exercise |
| 공부 | 공부하다 | 공부해요 | to study |
| 전화 | 전화하다 | 전화해요 | to make a call |
| 이야기 | 이야기하다 | 이야기해요 | to talk (with someone) |
| 말 | 말하다 | 말해요 | to talk, to say (to someone) |
| 회의 | 회의하다 | 회의해요 [회이해요] | to have a meeting |
하다 is irregular — 하 + 아요 should give 하요, and gives 해요 instead. It is the one you will use most, so the irregularity costs nothing.
Formal polite: -ㅂ니다 / -습니다
The 하십시오체 form. Here the rule is simpler — it depends on whether the stem ends in a vowel or a consonant, and nothing else.
| Ending | When | Statement | Question |
|---|---|---|---|
| -ㅂ니다 | Stem ends in a vowel | 가다 → 갑니다 | 갑니까? |
| 보다 → 봅니다 | 봅니까? | ||
| -습니다 | Stem ends in a consonant | 먹다 → 먹습니다 | 먹습니까? |
| 읽다 → 읽습니다 | 읽습니까? | ||
| -합니다 | noun + 하다 | 일하다 → 일합니다 | 일합니까? |
| 운동하다 → 운동합니다 | 운동합니까? |
With -ㅂ니다 the ㅂ is not a syllable of its own — it goes into the 받침 slot of the stem’s last syllable. 가 + ㅂ니다 = 갑니다.
Two things fall out of comparing the tables. First, the formal form asks and tells with different words (갑니다 / 갑니까?) while the casual form uses one for both (가요 / 가요?). Second, the formal form is easier to conjugate — no vowel harmony, no contractions. If you are unsure of a casual form under pressure, the formal one is both safer socially and simpler mechanically.
Practice
A: 지금 뭐 해요?
What are you doing now?
B: 일해요.
I'm working.
A: 리사 씨는 지금 뭐 해요?
What is Lisa doing now?
B: 리사 씨는 전화해요.
Lisa is making a call.
지금 is now; 뭐 is what, from lesson 108.
Work culture: where to sit
Korean seating is not arbitrary and it is not first-come. Every shared space has an upper seat (상석) and a lower seat, and the rule generating them is the same everywhere: the senior person sits furthest from the door.
The logic is practical rather than symbolic. Whoever is nearest the entrance deals with interruptions — the door, arriving documents, a call to fetch something. That is the junior’s job, so that is the junior’s seat.
In the meeting room
- Senior seats are in the middle of the table, facing away from the entrance.
- Junior seats are nearest the door.
- The junior sits by the door specifically because they will be getting up the most.
- Hold the door for seniors coming in and going out. This is baseline manners, not an extra courtesy.
In a car or taxi
| Seat | Who |
|---|---|
| Rear right (behind the front passenger) | The most senior — the most comfortable seat |
| Rear left | Second most senior |
| Rear middle | The junior |
| Front passenger | The junior — unless a senior is driving |
That last exception matters: if the senior person is driving themselves, the front passenger seat becomes the upper seat, and leaving it empty while you sit in the back is a small insult.
In the lift
- The senior stands in the far corner from the doors.
- The junior stands by the buttons.
- The junior presses the floor, and holds door open until everyone senior has left.
Greeting a group
Greet the highest-status person first, then the oldest. Those are not always the same person, and status wins.
How do you tell who that is before anyone has spoken? Watch the doorway — the most senior person walks in front and enters the room first. The order a Korean delegation walks through a door is a reliable org chart.
