These polite verb endings might seem tricky at first, but they follow simple patterns based on vowel harmony. Once you understand the rules, you’ll be able to speak confidently and politely in everyday conversations.
In this guide, you'll learn the difference between 아요 and 어요, when to use each one, how to conjugate verbs correctly, and how to apply them in real-life situations. We’ve also included examples, tables, and a short quiz to help you remember what you learn. Let’s go! 🇰🇷
1️⃣ What Are 아요 and 어요?
아요 and 어요 are polite present tense endings used in Korean. They’re part of the speech level known as 해요체, which is friendly and respectful — perfect for everyday conversations.
When you attach these endings to a verb stem, you're saying “I do,” “I eat,” “I go,” etc., in a polite and natural way. You’ll use this form constantly — at cafes, in stores, in class, or even with strangers.
For example: - 가다 (to go) → 가요 - 먹다 (to eat) → 먹어요 - 배우다 (to learn) → 배워요
Once you master these endings, you’ll be able to express almost anything in the present tense without sounding too casual or too formal.
🧾 Verb Ending Summary Table
| Verb | Stem | Ending | Conjugated |
|---|---|---|---|
| 가다 (to go) | 가 | -아요 | 가요 |
| 먹다 (to eat) | 먹 | -어요 | 먹어요 |
| 배우다 (to learn) | 배우 | -어요 → 워요 | 배워요 |
2️⃣ When to Use 아요 vs 어요
So how do you know whether to use 아요 or 어요? It depends on the **final vowel** in the verb stem.
Use 아요 if the verb stem’s last vowel is either “ㅏ” or “ㅗ”. Use 어요 for all other vowels like “ㅓ”, “ㅜ”, “ㅡ”, and “ㅣ”.
Some quick examples: - 오다 (to come) → 오 + 아요 = 와요 - 서다 (to stand) → 서 + 어요 = 서요 - 마시다 (to drink) → 마시 + 어요 = 마셔요
This system is consistent and easy to apply once you learn the vowel patterns. It also helps you pronounce things smoothly.
I’ve found that thinking in vowel sounds—not just rules—makes conjugation feel more natural over time.
📊 아요 vs 어요 Vowel Ending Comparison Table
| Verb | Stem Vowel | Rule | Conjugated |
|---|---|---|---|
| 오다 (to come) | ㅗ | Add -아요 | 와요 |
| 서다 (to stand) | ㅓ | Add -어요 | 서요 |
| 보다 (to see) | ㅗ | Add -아요 | 봐요 |
| 쓰다 (to write) | ㅡ | Add -어요 | 써요 |
This table helps you visualize how vowel harmony affects the ending. Once you memorize a few patterns, you’ll apply them naturally when speaking or writing. ✅
3️⃣ How to Conjugate Regular Verbs
Let’s go step by step. Most Korean verbs follow regular rules when conjugated into the present tense using 아요 or 어요. You simply remove the “다” from the verb and add the correct ending based on the last vowel.
For example: - 하다 → 하 + 여요 = 해요 - 가다 → 가 + 아요 = 가요 - 읽다 → 읽 + 어요 = 읽어요
If the verb ends in “ㅏ” or “ㅗ”, you add **-아요**. If it ends in any other vowel, you add **-어요**. If the verb is 하다, you change it to **해요**.
Once you get used to the pattern, it becomes second nature — like muscle memory. You’ll soon start guessing the right forms without needing to look them up.
🔍 Regular Verb Conjugation Table
| Infinitive | Stem | Ending Rule | Conjugated |
|---|---|---|---|
| 가다 | 가 | + 아요 (ㅏ vowel) | 가요 |
| 먹다 | 먹 | + 어요 (ㅓ vowel) | 먹어요 |
| 하다 | 하 | → 해요 (irregular rule) | 해요 |
4️⃣ Irregular Verbs and Exceptions
While many verbs follow the regular 아요/어요 rules, Korean has its share of **irregular verbs** that behave differently. These can be confusing, but they follow predictable patterns.
Some common types of irregulars include: - **르 Irregular** (e.g. 모르다 → 몰라요) - **ㅂ Irregular** (e.g. 돕다 → 도와요) - **ㄷ Irregular** (e.g. 듣다 → 들어요)
For example, 돕다 (to help) ends in ㅂ. That changes to 오 + 아요 → 도와요. Similarly, 듣다 (to listen) replaces ㄷ with ㄹ → 들어요.
These exceptions may look random, but the patterns are consistent. Once you see enough examples, they won’t surprise you anymore.
⚠️ Irregular Verb Examples Table
| Verb Type | Infinitive | Conjugated | Note |
|---|---|---|---|
| 르 Irregular | 모르다 | 몰라요 | Double ㄹ added |
| ㅂ Irregular | 돕다 | 도와요 | ㅂ → 오 |
| ㄷ Irregular | 듣다 | 들어요 | ㄷ → ㄹ |
