누르면 comes from the verb 누르다 (to press).

• verb stem: 누르-
• conditional ending: -면
• combined: 누르면

-면 means if or when, depending on context. In this sentence, it means something like:

• if you press this button
• when you press this button

Both are natural in English here.

It can feel like both.

In instructions or device descriptions, -면 often gives a general result:

• 이 버튼을 누르면... = If/When you press this button...

English often prefers when for something expected to happen, but if is also possible because it is still a condition. So this sentence is describing a normal cause-and-effect result.

Because 버튼 is the object of 누르다 (to press).

• 이 버튼을 = this button
  • object marker 을
• You are pressing the button, so the button receives the action.

That is why 을/를 is used here.

Because 지도 is the subject of 나오다.

나오다 literally means to come out, to appear, or to come up. The map is not being directly acted on; instead, the map is the thing that appears.

So:

• 지도가 나와요 = the map appears / comes up

Using 를 would suggest the map is a direct object, but 나오다 does not work that way here.

나와요 comes from 나오다.

Basic meaning of 나오다:

• to come out
• to appear
• to come up
• to be shown

In this sentence, it most naturally means:

• the map appears
• the map comes up
• the map is displayed

So although the literal image is comes out, in technology or screen contexts it often means shows up on the screen.

This is a normal conjugation pattern.

• dictionary form: 나오다
• stem: 나오-
• polite ending: -아요
• combined: 나오아요

In actual Korean, 오 + 아 contracts to 와, so:

• 나오아요 → 나와요

So 나와요 is just the natural polite present-tense form of 나오다.

-요 makes the sentence polite in everyday speech.

So 나와요 is a standard polite form, often used in:

• conversation
• instructions
• customer-facing writing
• apps and devices

Without -요, it would be plain style:

• 이 버튼을 누르면 지도가 나와.

That is less polite and more casual.

Yes. Korean usually puts the condition first and the main result later.

So the structure is:

• 이 버튼을 누르면 = if/when you press this button
• 지도가 나와요 = the map appears

Korean often follows this pattern:

condition + result

So a very literal order would be:

• This button press-if, map appears

That sounds strange in English, but it is normal in Korean.

Korean often leaves out the subject when it is obvious from context.

In a sentence like this, it is naturally understood that the user is the one pressing the button. So Korean does not need to say you explicitly.

A more literal English explanation would be:

• If you press this button, the map appears.

But in Korean, leaving out you is completely normal.

Literally, 이 버튼 means this button.

• 이 = this
• 버튼 = button

However, Korean does not use articles like a and the the way English does. So sometimes Korean expressions do not match English articles exactly.

In this sentence, 이 버튼 clearly points to a specific button near the speaker, on the screen, or in the shared context, so this button is the best translation.

Yes, absolutely.

In modern Korean, 지도가 나와요 very naturally means:

• the map appears on the screen
• the map comes up
• the map is displayed

So this sentence is very common for:

• apps
• navigation systems
• kiosks
• websites
• digital interfaces

It does not have to mean a paper map physically comes out.
