Questions & Answers about bang yeyageul miri haeya haeyo.

What does 방 예약을 미리 해야 해요 literally mean, and how is it structured?

Literally, it breaks down as:

• 방 (room)
• 예약을 (reservation + object marker)
• 미리 (in advance)
• 해야 해요 (must do / have to do)
  Altogether: “You have to reserve a room in advance.” It follows the typical Korean S–O–V order (Subject omitted) + adverb + necessity expression.

Why is 을 attached to 예약?

을 is the object particle marking 예약 as what you are doing. Without it, the verb 하다 wouldn’t know what you’re “doing.” So 예약을 하다 = “to make a reservation.”

What role does 미리 play, and can I move it around?

미리 means “in advance” or “ahead of time.” It’s an adverb modifying 해야 해요. You can generally place it before or after the object:

• 미리 방 예약을 해야 해요.
• 방 예약을 미리 해야 해요.
  Both are correct; the emphasis shifts slightly depending on placement but the meaning stays the same.

What is 해야 해요, and how does it express necessity?

해야 해요 comes from the verb 하다 (“to do”) plus the structure , which means “must” or “have to.” Conjugated politely in present tense, = “you must do.” So = “you have to make a reservation.”
