Questions & Answers about naeil hakgyoe gaya haeyo.
가야 해요 comes from the grammar pattern -아/어야 하다, which expresses must or have to. To form it:
- Remove 다 from 가다 → 가-
- Add -야 (because the stem ends in ㅏ) → 가야
- Attach 하다, then conjugate politely → 해요
Put together → 가야 해요 (“I have to go”).
Yes. -아/어야 되다 is another way to express obligation. In daily speech, many Koreans say 가야 돼요. The nuance is subtle:
- 해야 해요 (하다) often feels like a personal decision.
- 해야 돼요 (되다) can imply an external necessity or social rule.
In most contexts, they’re interchangeable.
The -요 ending is polite informal speech (해요체). It’s suitable for conversations with strangers or acquaintances.
- More formal: 가야 합니다 (하십시오체)
- More casual: 가야 해 (no -요) for close friends or family
Use 안 + verb stem + -아/어도 되다:
• 내일 학교에 안 가도 돼요 – “You don’t have to go to school tomorrow.”
Note: 못 가도 돼요 means “even if you can’t go,” which has a different nuance.
You can simply raise your intonation at the end:
• 내일 학교에 가야 해요?
For higher formality, use -습니까?:
• 내일 학교에 가야 합니까?
In Korean, expressing obligation with -아/어야 하다 uses the present tense and relies on the time adverbial (here 내일) to show when it applies. You could add a future nuance by saying:
• 내일 학교에 가야 할 거예요 – “I will have to go to school tomorrow,” but 가야 해요 plus 내일 already makes it clear.
