Sentence Structure and Basic Verbs

🎯

TL;DR — Korean Sentence Structure in 3 bullets

🔚 Korean is SOV: Subject → Object → Verb at the end. "I eat apples" becomes literally "I apples eat."

🔌 Particles tag each noun's role, so word order is flexible — but the verb always stays last.

🔀 Verbs come from a dictionary form ending in ~다 (가다, 먹다, 하다…); we conjugate the stem to make polite ~아/어요 endings.

Iru's Helper Note

안녕! 🦊 English brain says "I eat apples" → Korean brain says "I apples eat." Once you flip that switch — verb goes at the end — the rest of Korean sentence structure clicks fast. We'll use the particles you already learned (은/는/이/가/을/를) to glue everything together, then meet the magic verb ending ~아/어요 that turns dictionary words into real sentences. By the end of this lesson, you'll build your first Korean sentences from scratch! 🚀

Korean Helper Widgets in a side window and use the audio widget to compare "저는 사과를 먹어요" with the English "I eat apples." Notice how the verb 먹어요 is the last sound — that's the SOV signature.

🔚 Korean = SOV (Subject → Object → Verb)

English is SVO — Subject Verb Object. Korean is SOV — Subject Object Verb. The verb always sits at the end of the sentence.

Side-by-side comparison:

🍎 English: I (S) eat (V) apples (O).

🍎 Korean: 저는 (S) 사과를 (O) 먹어요 (V). (Literally: I apples eat.)

📖 English: She (S) reads (V) books (O).

📖 Korean: 그 사람은 (S) 책을 (O) 읽어요 (V).

☕ English: My friend (S) drinks (V) coffee (O).

☕ Korean: 친구가 (S) 커피를 (O) 마셔요 (V).

The golden rule: Once you set the verb at the end, everything else is just particles holding your nouns in place.

🔀 Word Order is Flexible — Verbs Are Not

Because Korean particles tag each noun's role, you can shuffle the noun groups around for emphasis. The verb still anchors the end.

All three of these mean "I eat apples":

🍎 저는 사과를 먹어요. (Standard SOV — most neutral.)

🍎 사과를 저는 먹어요. (Object first — emphasizes apples.)

🍎 저는, 사과를, 먹어요. (Pause-broken — stylistic, conversational.)

❌ What you can NOT do: 저는 먹어요 사과를. (Verb in the middle — sounds wrong.)

💡 Bottom line: Move nouns around for emphasis if you must, but the verb stays parked at the end.

🎯 Modifiers Come Before the Noun

Korean adjectives, possessives, and other modifiers always sit before the noun they modify — like in English, but more strictly.

🍎 빨간 사과 (red apple — modifier before noun)

🏠 우리 집 (our house — possessive before noun)

📖 재미있는 책 (interesting book — verb-form modifier before noun)

🏫 큰 학교 (big school)

In longer sentences this stacks up: Subject → (modifiers) → Object → Verb.

🍶 저는 따뜻한 커피를 마셔요. (I drink hot coffee.)

📝 친구가 재미있는 책을 읽어요. (My friend reads an interesting book.)

🔑 Verbs: The Dictionary Form Ends in ~다

Every Korean verb in a dictionary ends with ~다. This is the "raw" form — it never appears in real speech. We chop off 다 to find the stem, then add an ending.

Examples of dictionary form → stem:

🚶 가다 (to go) → stem: 가

🏃 오다 (to come) → stem: 오

🍚 먹다 (to eat) → stem: 먹

☕ 마시다 (to drink) → stem: 마시

📖 읽다 (to read) → stem: 읽

✍️ 쓰다 (to write) → stem: 쓰

🛌 자다 (to sleep) → stem: 자

👋 만나다 (to meet) → stem: 만나

🛍️ 사다 (to buy) → stem: 사

📚 공부하다 (to study) → stem: 공부하

💼 일하다 (to work) → stem: 일하

👁️ 보다 (to see/watch) → stem: 보

🎙️ Three Speech Levels (Quick Overview)

Korean has multiple politeness levels. We focus on the polite informal ~아/어요 for now — it's the everyday all-purpose form.

👔 Formal: 먹습니다 (news, business, military)

😊 Polite informal: 먹어요 (default for daily life with anyone you don't know super well)

👯 Casual: 먹어 (only with close friends, family, younger people)

We'll learn them all eventually — today's focus is ~아/어요.

✨ The ~아/어요 Conjugation — 3 Simple Rules

To make a verb stem polite, look at the last vowel in the stem and apply one of three rules:

🌗 Rule 1: If the last vowel is ㅏ or ㅗ → add 아요

🌙 Rule 2: If the last vowel is anything else → add 어요

🌟 Rule 3: If the verb is a 하다 verb → 하 + 여요 → contracts to 해요

Walkthrough — stem ends in ㅏ or ㅗ:

🚶 가다 → stem 가 → 가 + 아요 → 가아요 → contracts to 가요 (I go.)

🛍️ 사다 → 사 → 사 + 아요 → 사아요 → contracts to 사요 (I buy.)

🏃 오다 → 오 → 오 + 아요 → 오아요 → contracts to 와요 (I come.)

👁️ 보다 → 보 → 보 + 아요 → 보아요 → contracts to 봐요 (I see.)

Walkthrough — other vowels:

🍚 먹다 → 먹 → 먹 + 어요 → 먹어요 (I eat.)

📖 읽다 → 읽 → 읽 + 어요 → 읽어요 (I read.)

☕ 마시다 → 마시 → 마시 + 어요 → 마시어요 → contracts to 마셔요 (I drink.)

🛌 자다 → 자 → 자 + 아요 → 자아요 → contracts to 자요 (I sleep. — last vowel is ㅏ, so actually Rule 1!)

👋 만나다 → 만나 → 만나 + 아요 → 만나아요 → contracts to 만나요 (I meet. — last vowel is ㅏ → Rule 1.)

Walkthrough — 하다 verbs:

📚 공부하다 → 공부하 → 공부 + 해요 → 공부해요 (I study.)

💼 일하다 → 일해요 (I work.)

👊 운동하다 → 운동해요 (I exercise.)

❤️ 사랑하다 → 사랑해요 (I love.)

💡 Pro tip: Many of the most common Korean verbs are 하다 verbs, so the → 해요 ending unlocks tons of vocabulary instantly.

📖 12 Essential Verbs — Memorize These First

These twelve verbs power 80% of beginner Korean speech. Learn the dictionary form and the polite ~아/어요 form together.

🚶 가다 → 가요 (to go)

🏃 오다 → 와요 (to come)

🍚 먹다 → 먹어요 (to eat)

☕ 마시다 → 마셔요 (to drink)

👁️ 보다 → 봐요 (to see / watch)

📖 읽다 → 읽어요 (to read)

✍️ 쓰다 → 써요 (to write)

🛌 자다 → 자요 (to sleep)

👋 만나다 → 만나요 (to meet)

🛍️ 사다 → 사요 (to buy)

📚 공부하다 → 공부해요 (to study)

💼 일하다 → 일해요 (to work)

🧱 Building Your First Sentences

Now combine everything you know: pronoun + topic/object particles + verb.

🚶 저는 학교에 가요. (I go to school. — 에 = direction particle.)

☕ 나는 커피를 마셔. (I drink coffee. — casual ending 어 instead of 어요.)

📖 친구가 책을 읽어요. (My friend reads a book.)

🏫 동생은 학교에서 공부해요. (My younger sibling studies at school. — 에서 = location-action particle.)

🍚 우리는 김치를 먹어요. (We eat kimchi.)

💡 You haven't met 에 / 에서 yet — those are place/direction particles you'll learn next. They follow the same SOV rule: noun + particle + verb.

🇰🇷 Why This Matters

Korean's SOV order plus particle-driven grammar is what makes Korean radically different from English. The Korean government's official grammar reference at korean.go.kr describes Korean as a "head-final language" — the verb (the head of the sentence) comes at the end. Once your brain accepts this, you can decode any Korean sentence by walking right to left: find the verb, then read backwards through the particles to see who did what to whom.

The bonus payoff: because particles tag roles, listening comprehension in Korean rewards patience. The most important word — the verb — arrives last.

⚠️ Pitfalls

❌ Saying "저는 먹어요 사과를" (verb stuck in the middle — sounds wrong to Korean ears)

✅ "저는 사과를 먹어요" — verb at the end

❌ Using the dictionary form 먹다 in conversation (it sounds like a textbook header)

✅ Use 먹어요 (polite) or 먹어 (casual) when speaking

❌ Forgetting the conjugation contraction: 가아요 (uncontracted, sounds awkward)

✅ 가요 — contracts to a single syllable

❌ Using 하아요 / 하어요 for 하다 verbs

✅ 하다 verbs always become 해요 (irregular but consistent)

❌ Mixing speech levels (e.g., 저는 먹어) (formal subject + casual ending)

✅ Match the level: 저는 먹어요 (polite) / 나는 먹어 (casual)

🎉 You did it!

You now know the SOV blueprint, the verb-final rule, the dictionary-form-to-polite-form bridge, and twelve essential verbs. Combine these with your particles knowledge and you can build real Korean sentences from scratch! 정말 잘했어요! Onto practice! 🚀
