## 1. Why Korean Grammar Is Easier Than You Think

Before we start, let's bust some myths:

- **No grammatical gender.** Unlike French or German, Korean nouns don't have masculine/feminine forms. A table is just a table.

- **No articles.** No "a," "an," or "the" to worry about.

- **Verbs don't change with the subject.** In English, we say "I go" but "he goes." In Korean, the verb stays the same regardless of who's doing the action.

- **Consistent rules.** Korean has very few irregular verbs compared to English. Most grammar follows predictable patterns.

The only real challenge? **Word order** — Korean puts the verb at the end. But once you get used to it (and you will, fast), everything else flows naturally.

---

## 2. Korean Sentence Structure: Subject + Object + Verb

This is the **#1 most important thing** to understand.

English uses **SVO** (Subject → Verb → Object):

> **I** eat **pizza.**

Korean uses **SOV** (Subject → Object → Verb):

> **나는** 피자를 **먹어요.**

> **I** pizza **eat.**

### The Golden Rule

> 🔑 **The verb ALWAYS comes last in Korean.** Always. No exceptions.

Here are the three basic sentence patterns:

| Pattern | Example | Translation |

|---------|---------|-------------|

| Subject + Verb | 나는 자요. | I sleep. |

| Subject + Adjective | 나는 피곤해요. | I am tired. |

| Subject + Object + Verb | 나는 피자를 먹어요. | I eat pizza. |

### Pro Tip: You Can Drop the Subject

In Korean, if the subject is obvious from context, you can skip it entirely:

> 피자를 먹어요. (Eat pizza.) — Everyone already knows you mean "I."

This is why Korean conversations often sound much shorter than their English translations. Context is king.

---

## 3. Particles: The Tiny Words That Hold Everything Together

Particles are small markers attached to words that tell you **what role** each word plays in the sentence. Think of them as labels:

> "This word is the **subject**." "This word is the **object**." "This word is the **location**."

### The Essential Particles

#### Topic Markers: 은/는 (eun/neun)

Marks what the sentence is **about**.

- After a consonant → **은**: 선생님**은** (the teacher...)

- After a vowel → **는**: 나**는** (I...)

#### Subject Markers: 이/가 (i/ga)

Marks **who or what** does the action. Used for new information or emphasis.

- After a consonant → **이**: 학생**이** (the student...)

- After a vowel → **가**: 제가 (I... [formal, with emphasis])

> **은/는 vs. 이/가 — What's the difference?**

>

> - 은/는 = "Speaking of X..." (topic, general statements)

> - 이/가 = "X is the one that..." (specific subject, new info)

>

> Example:

> - 나**는** 학생이에요. = "**As for me**, I'm a student." (general intro)

> - 내**가** 학생이에요. = "**I'm** the one who's a student." (emphasis on "I")

#### Object Markers: 을/를 (eul/reul)

Marks the **object** — the thing receiving the action.

- After a consonant → **을**: 책**을** 읽어요. (I read a **book**.)

- After a vowel → **를**: 커피**를** 마셔요. (I drink **coffee**.)

#### Location Particles: 에 / 에서 (e / eseo)

- **에** = static location or destination: 학교**에** 가요. (I go **to** school.)

- **에서** = location of an action: 학교**에서** 공부해요. (I study **at** school.)

#### Other Must-Know Particles

| Particle | Meaning | Example |

|----------|---------|---------|

| 도 | also/too | 나**도** 가요. (I go **too**.) |

| 만 | only | 커피**만** 마셔요. (I drink **only** coffee.) |

| 의 | possessive ('s) | 나**의** 책 = **my** book |

| (으)로 | direction/means | 버스**로** 가요. (I go **by** bus.) |

| 부터 | from (time/place) | 월요일**부터** (from Monday) |

| 까지 | until/to | 금요일**까지** (until Friday) |

| 와/과, 하고 | and (connecting nouns) | 빵**하고** 우유 (bread **and** milk) |

---

## 4. Verbs: The Heart of Every Korean Sentence

Every Korean verb ends in **-다 (da)** in its dictionary form:

| Korean | Romanization | Meaning |

|--------|-------------|---------|

| 하다 | hada | to do |

| 가다 | gada | to go |

| 오다 | oda | to come |

| 먹다 | meokda | to eat |

| 마시다 | masida | to drink |

| 보다 | boda | to see/watch |

| 읽다 | ikda | to read |

| 쓰다 | sseuda | to write |

| 자다 | jada | to sleep |

| 있다 | itda | to have/exist |

| 없다 | eopda | to not have/not exist |

| 좋아하다 | joahada | to like |

| 사다 | sada | to buy |

| 알다 | alda | to know |

| 만나다 | mannada | to meet |

### The Magic of 하다 (hada) Verbs

One of the best things about Korean: you can make **hundreds** of verbs by adding 하다 (to do) to a noun:

| Noun | + 하다 | Meaning |

|------|--------|---------|

| 공부 (study) | 공부하다 | to study |

| 운동 (exercise) | 운동하다 | to exercise |

| 요리 (cooking) | 요리하다 | to cook |

| 전화 (phone call) | 전화하다 | to call |

| 일 (work) | 일하다 | to work |

| 노래 (song) | 노래하다 | to sing |

| 사랑 (love) | 사랑하다 | to love |

Once you learn this pattern, your vocabulary grows exponentially.

---

## 5. Verb Conjugation: Simpler Than You'd Expect

Here's where Korean gets beautifully logical.

### Step 1: Find the Verb Stem

Remove **-다** from the dictionary form:

| Dictionary Form | Verb Stem |

|----------------|-----------|

| 먹다 (to eat) | 먹 |

| 가다 (to go) | 가 |

| 마시다 (to drink) | 마시 |

| 하다 (to do) | 하 |

### Step 2: Apply the Conjugation Rule

For polite present tense (the form you'll use 90% of the time):

> **If the last vowel in the stem is ㅏ or ㅗ → add 아요**

> **For all other vowels → add 어요**

> **하다 always becomes → 해요**

| Verb | Stem | Last Vowel | Conjugation | Result |

|------|------|-----------|-------------|--------|

| 가다 | 가 | ㅏ | + 아요 → 가아요 → | **가요** (contracted) |

| 오다 | 오 | ㅗ | + 아요 → 오아요 → | **와요** (contracted) |

| 먹다 | 먹 | ㅓ | + 어요 → | **먹어요** |

| 마시다 | 마시 | ㅣ | + 어요 → 마시어요 → | **마셔요** (contracted) |

| 하다 | 하 | — | → | **해요** (always) |

That's it. **One rule** covers nearly every verb.

### Important: Verbs Don't Change by Person

| English (changes) | Korean (doesn't change) |

|-------------------|------------------------|

| I **go** | 나는 **가요** |

| You **go** | 너는 **가요** |

| She **goes** | 그녀는 **가요** |

| We **go** | 우리는 **가요** |

Same form. Every time. Beautiful, right?

---

## 6. Tenses: Past, Present, and Future

### Present Tense (-아요/어요)

You already learned this above. It covers both present and habitual actions:

> 저는 커피를 마셔요. = I drink coffee. / I am drinking coffee.

### Past Tense (-았어요/었어요)

Same vowel rule as present, but with **-았/었** + 어요:

| Rule | Example |

|------|---------|

| Last vowel ㅏ/ㅗ → 았어요 | 가다 → **갔어요** (went) |

| Other vowels → 었어요 | 먹다 → **먹었어요** (ate) |

| 하다 → 했어요 | 공부하다 → **공부했어요** (studied) |

More examples:

| Verb | Past Tense | Meaning |

|------|-----------|---------|

| 보다 (see) | 봤어요 | saw |

| 오다 (come) | 왔어요 | came |

| 마시다 (drink) | 마셨어요 | drank |

| 자다 (sleep) | 잤어요 | slept |

| 있다 (exist) | 있었어요 | was/existed |

### Future Tense

Korean has three ways to express the future:

**1. -(으)ㄹ 거예요 — General future (most common)**

> 내일 갈 거예요. = I will go tomorrow.

- Vowel-ending stem → add -ㄹ 거예요: 가 → 갈 거예요

- Consonant-ending stem → add -을 거예요: 먹 → 먹을 거예요

**2. -(으)ㄹ게요 — Promise or decision (first person only)**

> 제가 할게요. = I'll do it. (I promise / I've decided)

**3. -겠어요 — Strong will or intention**

> 열심히 하겠어요. = I WILL work hard.

**For beginners:** Just master **-(으)ㄹ 거예요** first. It covers 80% of future situations.

---

## 7. Speech Levels: Being Polite in Korean

Korean has **7 speech levels**, but don't panic — you only need **3** as a beginner:

### The Three Levels You Actually Need

| Level | Ending | When to Use | Example |

|-------|--------|------------|---------|

| **Formal** (합쇼체) | -ㅂ니다/습니다 | Business, presentations, news, strangers | 감사합니다 (Thank you) |

| **Polite** (해요체) | -아요/어요 | Everyday conversations, most situations | 감사해요 (Thanks) |

| **Casual** (해체) | -아/어 | Close friends, younger people | 고마워 (Thanks) |

### Which Should You Use?

> 🔑 **Start with 해요체 (polite) for everything.** It's safe in 95% of situations.

Switch to formal (-ㅂ니다) for:

- Job interviews

- Presentations

- Speaking to much older people you've just met

Switch to casual (-아/어) only with:

- Close friends your age or younger

- Children

- People who've explicitly said "let's speak casually" (반말 하자!)

### Examples Across All Three Levels

| Meaning | Formal | Polite | Casual |

|---------|--------|--------|--------|

| I go | 갑니다 | 가요 | 가 |

| I eat | 먹습니다 | 먹어요 | 먹어 |

| Thank you | 감사합니다 | 감사해요 | 고마워 |

| I'm sorry | 죄송합니다 | 죄송해요 | 미안해 |

---

## 8. Adjectives: They Work Like Verbs

This is one of the most unique things about Korean: **adjectives conjugate just like verbs.**

In English: "The food **is** delicious." (You need "is.")

In Korean: 음식이 맛있어요. (The adjective IS the verb. No "is" needed.)

### Common Korean Adjectives

| Korean | Meaning | Polite Form |

|--------|---------|-------------|

| 크다 | to be big | 커요 |

| 작다 | to be small | 작아요 |

| 좋다 | to be good | 좋아요 |

| 나쁘다 | to be bad | 나빠요 |

| 예쁘다 | to be pretty | 예뻐요 |

| 맛있다 | to be delicious | 맛있어요 |

| 재미있다 | to be fun | 재미있어요 |

| 비싸다 | to be expensive | 비싸요 |

| 싸다 | to be cheap | 싸요 |

| 덥다 | to be hot (weather) | 더워요 |

| 춥다 | to be cold (weather) | 추워요 |

### Adjectives Before Nouns

When an adjective comes **before** a noun, add **-ㄴ/은** to the stem:

| Adjective | + Noun | Meaning |

|-----------|--------|---------|

| 작다 → 작**은** | 작은 집 | small house |

| 크다 → 큰 | 큰 가방 | big bag |

| 예쁘다 → 예쁜 | 예쁜 꽃 | pretty flower |

| 좋다 → 좋**은** | 좋은 사람 | good person |

---

## 9. Negation: Saying "Not" and "Can't"

### "Not" — Two Ways

**Method 1: 안 (an) before the verb** (shorter, more conversational)

> 안 먹어요. = I don't eat.

**Method 2: -지 않다 (ji anta) after the stem** (slightly more formal)

> 먹지 않아요. = I don't eat.

### "Can't" — Two Ways

**Method 1: 못 (mot) before the verb**

> 못 가요. = I can't go.

**Method 2: -지 못하다 (ji mothada) after the stem**

> 가지 못해요. = I can't go.

### "Don't!" — Negative Commands

> -지 마세요 (ji maseyo) = Please don't...

- 걱정하지 마세요. = Please don't worry.

- 가지 마세요. = Please don't go.

### Quick Negation Cheat Sheet

| What You Want to Say | Korean Pattern | Example |

|---------------------|----------------|---------|

| I don't... | 안 + verb | 안 해요 (I don't do it) |

| I can't... | 못 + verb | 못 해요 (I can't do it) |

| Don't...! | verb stem + 지 마세요 | 하지 마세요 (Don't do it) |

| There isn't... | 없어요 | 시간이 없어요 (There's no time) |

## 10. Essential Connectors: Building Longer Sentences

Once you can make simple sentences, connectors let you combine them:

### -고 (go) — "and" / "and then"

> 커피를 마시**고** 공부해요.

> I drink coffee **and** study.

### -지만 (jiman) — "but"

> 비싸**지만** 맛있어요.

> It's expensive **but** delicious.

### -아/어서 (aseo/eoseo) — "because" / "so"

> 배가 고파**서** 밥을 먹었어요.

> I was hungry, **so** I ate.

### -(으)면 (myeon) — "if" / "when"

> 시간이 있**으면** 같이 가요.

> **If** you have time, let's go together.

### -(으)면서 (myeonseo) — "while"

> 음악을 들**으면서** 공부해요.

> I study **while** listening to music.

### -기 전에 (gi jeone) — "before"

> 자**기 전에** 책을 읽어요.

> I read a book **before** sleeping.

### -(으)ㄴ 후에 (hu-e) — "after"

> 밥을 먹**은 후에** 운동해요.

> I exercise **after** eating.

---

## 11. Questions in Korean

Good news: making questions in Korean is **incredibly simple.**

### In Polite Speech (해요체)

Just raise your intonation at the end. The sentence stays exactly the same:

> 커피를 마셔요. = I drink coffee. (statement ↘)

> 커피를 마셔요? = Do you drink coffee? (question ↗)

### In Formal Speech (합쇼체)

Change -ㅂ니다 to **-ㅂ니까**:

> 한국어를 공부합니**다**. = I study Korean. (statement)

> 한국어를 공부합니**까**? = Do you study Korean? (question)

### Question Words

| Korean | Romanization | Meaning |

|--------|-------------|---------|

| 뭐 / 무엇 | mwo / mueot | what |

| 누구 | nugu | who |

| 어디 | eodi | where |

| 언제 | eonje | when |

| 왜 | wae | why |

| 어떻게 | eotteoke | how |

| 얼마 | eolma | how much |

| 몇 | myeot | how many |

### Examples

> 이거 **뭐**예요? = **What** is this?

> **어디**에 가요? = **Where** are you going?

> **왜** 한국어를 공부해요? = **Why** do you study Korean?

> 이거 **얼마**예요? = **How much** is this?

---

## 12. Numbers and Counters

Korean has **two number systems**. Yes, two. But don't worry — each has a clear use case.

### Native Korean Numbers (하나, 둘, 셋...)

Used for: **counting things, age, hours**

### Counters (What Makes Korean Special)

In Korean, you need a **counter word** between the number and the thing you're counting:

> Number + Counter + Noun (or Noun + Number + Counter)

| Counter | Used For | Example |

| 개 (gae) | General objects | 사과 두 개 = 2 apples |

---

## 13. Honorifics: Showing Respect

Korean culture deeply values respect, and the language reflects this through **honorifics (존댓말, jondaemal).**

### The Honorific Infix: -시- (si)

Add **-시-** to the verb stem when talking **about** someone you respect:

> 선생님이 가**시**어요. → 선생님이 가**세요**. = The teacher goes.

> 어머니가 주무**세요**. = Mother is sleeping.

### Special Honorific Verbs

Some verbs have completely different honorific forms:

| Normal Verb | Honorific Verb | Meaning |

|------------|----------------|---------|

| 먹다 (eat) | 드시다 / 잡수시다 | to eat (respectful) |

| 자다 (sleep) | 주무시다 | to sleep (respectful) |

| 있다 (be/exist) | 계시다 | to be (respectful) |

| 말하다 (speak) | 말씀하시다 | to speak (respectful) |

| 죽다 (die) | 돌아가시다 | to pass away (respectful) |

### Honorific Particles

| Normal | Honorific | Usage |

|--------|-----------|-------|

| 이/가 (subject) | **께서** | 선생님**께서** 오셨어요. |

| 에게 (to someone) | **께** | 할머니**께** 드렸어요. |

### Address Terms

| Term | Usage |

|------|-------|

| -씨 (ssi) | Mr./Ms. — standard polite |

| -님 (nim) | Respected — more formal |

| 선생님 (seonsaengnim) | Teacher / Mr./Ms. (respectful) |

| 사장님 (sajangnim) | Company president |

| 언니/오빠/누나/형 | Older sister/brother (varies by speaker's gender) |
