What Does -아/어/여야 하다 Mean?
The -아/어/여야 하다 pattern is a grammatical construction used to express a sense of obligation, necessity, or requirement. In English, it corresponds to “must,” “have to,” or “should.” This structure is commonly used in both spoken and written Korean when you want to state that something is necessary or mandatory.
Breaking Down the Pattern
- Verb Stem + -아야 하다: Used when the last vowel of the verb stem is either ㅏ or ㅗ.
- Verb Stem + -어야 하다: Used with other vowels.
- Verb Stem + -여야 하다: Used for 하다 verbs (to do).
The verb 하다 (to do) in this construction serves the function of “have to” or “must.” The pattern can also appear as -아/어/여야 되다, which is interchangeable in most contexts.
How to Form -아/어/여야 하다
To create this pattern, follow these simple steps:
- Take the verb stem (remove 다 from the dictionary form).
- Add -아야, -어야, or -여야 depending on the last vowel of the stem.
- Add 하다 to the end.
Examples:
- 가다 (to go) → 가 + 아야 하다 → 가야 하다 (must go)
- 먹다 (to eat) → 먹 + 어야 하다 → 먹어야 하다 (must eat)
- 공부하다 (to study) → 공부하 + 여야 하다 → 공부해야 하다 (must study)
Negative Form
To express that you “must not” do something, use -아/어/여서는 안 되다 instead of -아/어/여야 하다.
- 가다 (to go) → 가 + 아서는 안 되다 → 가서는 안 되다 (must not go)
