Questions & Answers about biga geuchimyeon usaneul an sseodo dwaeyo.

What does -면 mean here—if or when?

-면 is a conditional ending that can mean if or when, depending on context.
In 비가 그치면, it often sounds like when/once it stops raining (a likely future situation), but it can also be understood as if it stops raining.


Why is it 비가 and not 비는?

비가 uses the subject marker -가, which commonly introduces the subject in a neutral, “what happens is…” way: the rain stops.
비는 (topic marker -는) would shift the nuance to “as for rain…”—often for contrast or a broader topic.
So 비가 그치면 is the most natural for simply stating the condition.


How is 그치면 formed?

The verb is 그치다 (to stop, e.g., rain/wind/noise).
Stem: 그치- + -면그치면.
It means if/when (it) stops.


Does 그치다 mean “to stop” in general, like “stop doing something”?

Usually 그치다 is used for something that stops on its own or naturally ends: rain, snow, wind, noise, a cough, etc.
For “stop doing (an action)” you more often use:

  • 멈추다 (stop moving/stop an action)
  • 그만하다 (quit/stop doing)

Example difference:

  • 비가 그쳤어요 = The rain stopped.
  • 그만해! = Stop it!/Quit it!

Why is it 우산을? Can that be omitted?

우산을 has the object marker -을 because 쓰다 (to use/wear) takes an object: use an umbrella.
In real conversation, it can be omitted if it’s obvious:

  • 비가 그치면 안 써도 돼요. = If it stops raining, you don’t have to (use it).

What exactly does do, and why is it placed there?

is the short form of negation meaning not. It typically goes right before the verb (or verb phrase):

  • 안 써요 = (I) don’t use (it).
  • 우산을 안 써도 돼요 = (You) don’t have to use an umbrella.

What’s the difference between and ?
  • = don’t / not (choice, intention, general negation)
  • = can’t / unable to (lack of ability or circumstances)

So:

  • 우산을 안 써요 = I don’t use an umbrella (by choice / I just don’t).
  • 우산을 못 써요 = I can’t use an umbrella (hands are full, it’s broken, etc.).

In this sentence, the meaning is “no need to,” so fits.


How does -아/어도 돼요 work here?

-아/어도 돼요 means it’s okay to… / you may…, and very commonly it also implies you don’t have to… in context.
So 안 써도 돼요 literally is Even if you don’t use it, it’s okay → naturally: You don’t have to use it.


Why is it 써도 and not 쓰도?

The verb is 쓰다. With -아/어도, 쓰다 conjugates to :

  • 쓰다 → 써요 So:
  • 써 + 도써도.

This is a regular conjugation pattern for -type verbs like 쓰다.


Can I also say 우산을 쓰지 않아도 돼요? Is it different?

Yes.

  • 우산을 안 써도 돼요 = more casual/short, very common in speech
  • 우산을 쓰지 않아도 돼요 = a bit more explicit and slightly more formal/neutral

Both mean you don’t have to use an umbrella.


Is the sentence ordering flexible? Can the clauses be swapped?

Yes. Korean often allows swapping as long as the meaning stays clear:

  • 비가 그치면 우산을 안 써도 돼요.
  • 우산을 안 써도 돼요, 비가 그치면. (less common, but possible with a pause)

The first version is more natural and straightforward.


Why is it written 돼요 and not 되요?

The correct spelling is 돼요. It comes from 되다 → 되어 → 돼 (contraction), then 돼요 in polite speech.
되요 is a very common misspelling, but standard Korean writes 돼요.
