Questions & Answers about biga omyeon usaneul sseoya haeyo.
Why does 오다 become 오면, and what is the function of -면 here?
The suffix -면 attaches to a verb stem to create a conditional clause, meaning “if…” or “when…”. You take the stem of 오다 (“오-”) and add -면, giving you 오면 (“if it comes,” i.e. “if it rains”).
What is the purpose of -아/어야 해요 in 써야 해요, and how does it convey obligation?
-아/어야 해요 is used to express necessity or obligation, equivalent to “have to” or “must.” You attach -아야 or -어야 to the verb stem and then add 해요. Here, 쓰다 (to use/put on) → 써- + -야 해요 = 써야 해요, meaning “you have to use (an umbrella).”
What is the difference between 해야 해요 and 해야 돼요?
Both mean “have to do.”
- 해야 해요 comes from 하다 + necessity (“to have to”).
- 해야 돼요 comes from 하다 + 되다 (“to become necessary”).
In everyday speech they are almost interchangeable, though some speakers feel -해요 is slightly more direct and -돼요 a bit softer.
