1. Definition
The ‘아/어’ ending is a fundamental verb conjugation in Korean, primarily used in informal speech (반말체). It corresponds to various English tenses and can form commands or requests.
2. Form (Structure)
Add ‘아/어’ to the verb stem after removing ‘다’. The choice between ‘아’ or ‘어’ depends on the verb stem’s last vowel.
To conjugate a verb or adjective with ‘아/어’:
- If the verb stem has ㅏ or ㅗ as the final vowel, use ‘아’.
- If the verb stem has other vowels (ㅓ, ㅜ, ㅡ, ㅣ), use ‘어’.
- Special cases apply to 하다-verbs, which change to ‘해’.
Table summary:
| Last vowel | Add | Example |
| ㅏ, ㅗ | 아 | 가다 → 가 |
| Others | 어 | 먹다 → 먹어 |
| 하다 | 해 | 공부하다 → 공부해 |
