In Korean, you can’t make a full sentence without understanding particles. Among the most common and essential are the object particles 을/를 – and they’re surprisingly easy to use once you get the hang of it! 🧩

These little markers come right after the object of the sentence and tell us what is being acted upon. Mastering 을/를 will instantly improve your sentence-making skills in Korean. Let’s break it down in a way that actually sticks! 💡
📘 What Are Object Particles in Korean?
Object particles show which noun in the sentence is receiving the action of the verb. In English, we use word order to show this: "I eat apples." → "Apples" is the object.
In Korean, you can rearrange words a bit, so particles help identify sentence roles clearly. 을/를 always attach directly to the object noun.
They’re used in both written and spoken Korean—formally and casually. Learning them is step one to sounding like you know what you’re doing. 😎
📊 Object Particle Basics
| Particle | Used After | Example |
|---|---|---|
| 을 | Noun ending in a consonant | 빵을 먹어요 |
| 를 | Noun ending in a vowel | 사과를 먹어요 |
🧠 When to Use 을 vs. 를
Choosing between 을 and 를 is based only on whether the object ends in a consonant or vowel—no need to worry about anything else!
- 📘 Use 을 if the noun ends in a consonant.
Example: 책 → 책을 읽어요 - 📗 Use 를 if the noun ends in a vowel.
Example: 바나나 → 바나나를 먹어요
That’s it. One of the simplest grammar rules in Korean – and thankfully, one of the most consistent too. ✔️

🧱 The Role of Object Particles in Sentences
In Korean, the object particle 을/를 marks the direct object – the thing being acted upon by the verb. Without it, your listener may not understand what’s receiving the action. 🎯
For example, in the sentence "나는 사과를 먹어요" (I eat an apple), “사과” (apple) is the object, and 를 tells us it’s being eaten. Without 를, the meaning could get lost or sound awkward, especially in formal situations.
Because Korean allows for flexible word order, these particles are essential for clarity. You could say "사과를 나는 먹어요" and it still makes sense, thanks to the particle.
📊 Sentence Role Example
| Sentence | Object | Verb |
|---|---|---|
| 나는 밥을 먹어요 | 밥을 (rice) | 먹어요 (eat) |
| 그녀는 책을 읽어요 | 책을 (book) | 읽어요 (read) |

❌ Can You Omit Object Particles?
Technically, yes—you might hear native speakers drop 을/를 in casual conversations. But it depends on clarity.
If the sentence is short and the context is obvious, dropping the particle is okay. For example: - “밥 먹었어?” (You ate rice?) - “책 읽었어?” (You read the book?)
However, in formal speech, writing, or longer sentences, it’s best to include them to avoid confusion.
📊 Omission Examples
| Full Sentence | Omitted Version | Context |
|---|---|---|
| 사과를 먹었어 | 사과 먹었어 | Casual |
| 책을 읽었어요 | 책 읽었어요 | Still understood |

❓ FAQ
Q1. What’s the difference between 을 and 를?
A1. It’s based on the final sound of the noun. Use 을 if the object ends in a consonant, and 를 if it ends in a vowel.
Q2. Can I leave out 을/를 in conversations?
A2. Sometimes, yes. In casual speech, native speakers may drop them when the meaning is clear. But for learners, it’s better to use them until it feels natural.
Q3. Are 을/를 used in questions too?
A3. Absolutely. For example, “뭐를 먹어요?” means “What are you eating?” The particle is key for clarity.
Q4. Do 을/를 change based on formality?
A4. No. The particle stays the same in both formal and informal speech. Only the verb ending changes based on politeness level.
Q5. What if I accidentally use 을 instead of 를?
A5. Native speakers will still understand, but it will sound a bit off. It’s like saying “an apple” as “a apple” in English—comprehensible but incorrect.
Q6. Is there ever a time when 을/를 aren’t used with objects?
A6. Occasionally, when the object is vague or implied, it may be dropped, especially in commands or short phrases. But in full sentences, it’s recommended to include them.
Q7. Can 을/를 be used more than once in a sentence?
A7. Yes! If there are two or more objects in a sentence, each gets its own particle. For example: “나는 사과를 먹고 우유를 마셔요.”
Q8. Are there exceptions to the 을/를 rule?
A8. Not really! 을/를 is one of the most consistent rules in Korean grammar, which is why it's perfect for beginners to master early on. 🙌
