Questions & Answers about naeireun kkok hakgyoe gaya haeyo.

In 내일은, why is the topic marker -은 used instead of the subject marker -이?
The particle -은 marks 내일 (“tomorrow”) as the topic, signaling “as for tomorrow…”. If you used 내일이, you’d simply be stating “tomorrow” as the grammatical subject. Using -은/는 often adds a contrastive or topical nuance, like “speaking of tomorrow…”.
What does add to the sentence?
means “definitely,” “without fail,” or “for sure.” It emphasizes that going to school is non‐negotiable: 내일은 꼭 학교에 가야 해요 = “Tomorrow I absolutely must go to school.”
Why is the particle used in 학교에 가야 해요?
The particle marks the destination or direction of movement. When you go somewhere, you attach to the place name. Thus 학교에 means “to school.”
How does 가야 해요 express obligation?

가야 해요 comes from the structure -아/어야 하다, which expresses necessity or obligation. Here’s the breakdown:
1) 가다 (“to go”) → stem 가-
2) Add -아야가야 (“must go”)
3) Attach 하다 and make it polite → 가야 해요 (“have to go”)

Can you break down the formation of 가야 해요 step by step?
  1. Start with 가다 (to go).
  2. Drop -다, leaving 가-.
  3. Add -아야 (from -아/어야 하다):
    • = 가야 (“must go”).
  4. Add 하다 as the main verb: 가야 하다.
  5. Conjugate 하다 politely: 가야 해요.
Is there a difference between 가야 해요 and 가야 돼요?

No significant difference in meaning—they both mean “must go.”

  • 가야 해요 comes from -아야 하다.
  • 가야 돼요 comes from -아야 되다.
    Both are common; -돼요 can sound a bit more colloquial, but they’re interchangeable.
Could you use 내일은 꼭 학교에 가야 돼요 instead, and would it be correct?
Yes. 내일은 꼭 학교에 가야 돼요 is perfectly correct. It simply uses -아야 되다 for obligation. The overall meaning is still “I absolutely must go to school tomorrow.”
How would you say this sentence in a more casual (informal) style?

You can drop the polite endings:

  • 내일은 꼭 학교에 가야 해.
  • 내일은 꼭 학교에 가야 돼.
    Even shorter:
  • 내일 꼭 학교 가야 돼.
