Questions & Answers about eotteohge pyeonjireul sseoya hae?
What does 어떻게 mean in this sentence?
Why is 편지를 marked with -를?
What does 써야 해 mean? Why not just 써?
써야 해 expresses obligation or necessity. It breaks down as:
• 써- (verb stem of 쓰다, “to write”)
• -야 (connective ending, “must/have to”)
• 해 (casual form of 하다, “to do”)
So 써야 해 means (I/you/we) must write, not just “write.”
Why is there no subject like 내가 in the sentence?
What tense and politeness level is 써야 해?
This is present tense with a casual/informal ending. For other levels:
• Polite: 어떻게 편지를 써야 해요?
• Formal: 어떻게 편지를 써야 합니까?
What’s the difference between 써야 해 and 써야 돼?
Both mean must write or have to write.
• 써야 해 comes from 해야 하다 (“have to do”).
• 써야 돼 comes from 해야 되다 (also “have to do”).
There’s no major difference in meaning—just a slight variation in everyday speech.
How can I make this sentence more respectful toward the listener?
You can use the honorific verb 쓰시다:
• Polite honorific: 어떻게 편지를 쓰셔야 해요?
• Formal honorific: 어떻게 편지를 쓰셔야 합니까?
Can I rephrase it as 어떻게 편지를 쓰면 돼? Is the nuance different?
Yes. -으면 되다 (e.g. 쓰면 돼) asks “What should I do so that it’s okay?” rather than emphasizing obligation.
• 써야 해 → stresses necessity (“I must write”).
• 쓰면 돼 → focuses on the steps or method that will work. Both are common in conversation.
