Obligation in Korean often uses verb stem + -아/어야 하다.
• 씻다 → stem 씻- + 어야 = 씻어야 (“must wash”)
• Then add 하다, conjugated politely as 해요.
So 씻어야 해요 = “you have to wash.”
Both express necessity, but:
• 씻어야 해요 focuses on the speaker’s judgment (“I say you must wash”).
• 씻어야 돼요 comes from 되다 (“to become”), meaning “it becomes that you must wash,” sounding a bit more like an external rule or situation. In daily speech they’re interchangeable.
Korean is relatively flexible because case markers (like 에, -을) show each word’s role. You could say:
• 꼭 손을 씻고 집에 가기 전에 해요 (less natural)
• 집에 가기 전에 손을 꼭 씻어야 해요 (moves 꼭 after 손을 without changing meaning)
But the main verb 씻어야 해요 must stay at the end of its clause. The time clause 집에 가기 전에 normally comes before the main verb.
