Questions & Answers about jamkkan changmuneul yeoreodo dwaeyo?

What does -아/어도 돼요? mean in this sentence, grammatically?

-아/어도 돼요? is a very common permission pattern meaning “Is it okay if I…?” / “May I…?”
Structure: Verb stem + 아/어도 + 돼요?
Here: 열다 (to open) → 열어도 돼요? = “Is it okay if I open (it)?”
Literally it’s like “Even if I open it, is it okay?” → natural English: “Can I open it?”

Why is it 열어도 and not 열아도 or something else?

Because of Korean verb conjugation rules:

• Dictionary form: 열다
• Verb stem: 열-
• Add -어도 (since 열- takes -어): 열어도 So 열어도 = “even if (I) open / if (I) open (it’s okay).”

What is the role of 잠깐 here, and where can it go in the sentence?

잠깐 means “for a moment / briefly / just a second.” It softens the request and specifies it won’t be long.
It can move around fairly freely depending on emphasis, for example:

• 잠깐 창문을 열어도 돼요? (common, neutral)
• 창문을 잠깐 열어도 돼요? (emphasis on “open the window briefly”) Both are natural.

Why is 창문을 marked with -을?

-을/를 marks the direct object of the verb.
Here, the verb 열다 (to open) takes an object: you open something → 창문 (window) is that object, so 창문을.

Do I have to include 창문을? Could it be omitted?

It can be omitted if it’s already obvious from context:

• 잠깐 열어도 돼요? = “Is it okay if I open it for a moment?” Korean often drops objects when they’re understood.

What does 돼요 mean here? Is it the same as 되다?

Yes. 돼요 is the polite present form of 되다 (“to become / to be okay / to work out”).
In the permission pattern -아/어도 돼요, 돼요 means “it’s okay / it’s allowed.”
So 열어도 돼요? literally is “Is it okay if (I) open (it)?”

How polite is 열어도 돼요? and what are more polite or more casual alternatives?

열어도 돼요? is polite-informal (common everyday polite speech).
More polite:

• 잠깐 창문을 열어도 될까요? (softer, more formal “May I…?”)
• 잠깐 창문을 열어도 되겠습니까? (very formal) More casual (to close friends):
• 잠깐 창문 열어도 돼?

What’s the difference between 열어도 돼요? and 열면 돼요?

They’re different:

• 열어도 돼요? = asking permission (“Is it okay if I open it?”)
• 열면 돼요? = asking about the correct action/solution (“Do I just open it?” / “Is it enough if I open it?”) So for requesting permission, -아/어도 돼요? is the natural choice.

Why is there a question mark—how is this sentence “made” into a question in Korean?

In speech, it becomes a question mainly through intonation (rising tone at the end).
The ending -요 is polite; the question feeling comes from the spoken intonation and the context. In writing, the ? marks it clearly.

Can I say 잠시 instead of 잠깐?

Often yes:

• 잠시 창문을 열어도 돼요? is also natural and means “for a short while.” Nuance:
• 잠깐 often feels like very brief / just a second (more casual and common in requests).
• 잠시 can feel a bit more neutral or slightly more formal than 잠깐.

Is 열다 the right verb for opening a window? Are there other common verbs?

Yes, 창문을 열다 is the standard, most common way to say “open the window.”
You might also hear:

• 창문 좀 열어 주세요. = “Please open the window (a bit).” (requesting someone else) But for “May I open the window?” the sentence you have is exactly the natural verb choice.
