이 길로 means by this road, along this road, or more naturally in English, this way / down this road.

The particle -로 often marks:

• direction: toward, by way of
• means/method: by, with
• route/path: along, through

In this sentence, it marks the route you take. So 이 길로 가면 is literally something like if you go by this road.

Compare:

• 이 길로 가세요. = Go this way / Go along this road.
• 버스로 가요. = I go by bus.

가면 is 가다 (to go) + -면, which means if or when.

So:

• 가다 = to go
• 가면 = if you go / when you go

In this sentence, 이 길로 가면 means:

• if you go this way
• or when you go this way

In Korean, -면 can sound natural in both if and when situations depending on context.

Examples:

• 비가 오면 안 가요. = If it rains, I won’t go.
• 집에 가면 전화할게요. = When I get home, I’ll call.

This is a very common question because 나오다 can be used in different ways.

Here, 학교가 나와요 does not mean someone exits the school. Instead, it means the school appears, comes into view, or you come across the school.

So 학교가 is the thing that appears, which is why it takes -가 as the subject marker.

In this sentence:

• 학교가 나와요 = the school appears / you’ll see the school

But in a different sentence:

• 학교를 나와요 can mean to leave school or to graduate from school, depending on context.

So the particle changes because the meaning of 나오다 changes.

Yes, 나와요 comes from 나오다, which literally means to come out.

But Korean uses 나오다 in a broader way than English come out. It can mean:

• to come out
• to appear
• to emerge
• to show up
• to come into view

So in a road/direction context, 학교가 나와요 means:

• the school comes into view
• you’ll come across the school
• you’ll see the school

This is more natural in English than saying the school comes out.

Similar examples:

• 앞에 편의점이 나와요. = A convenience store will appear ahead / You’ll see a convenience store ahead.
• 지하철역이 바로 나와요. = The subway station comes right up / You’ll see the subway station right away.

Korean often uses the present tense form to talk about future results when the meaning is clear from context.

So 이 길로 가면 학교가 나와요 literally uses present-style forms, but the meaning is naturally:

• If you go this way, the school will appear
• If you go down this road, you’ll see the school

This is very normal in Korean.

English often prefers will for future results, but Korean does not always need a separate future form.

You could think of it as a general fact:

• When/if someone goes this way, the school appears.

Yes. Korean often leaves out subjects when they are obvious from context.

In this sentence, the listener is probably asking for directions, so 가면 is understood as:

• if you go
• if one goes

The full idea could be something like:

• (당신이) 이 길로 가면 학교가 나와요.

But saying 당신 is usually unnecessary and can even sound awkward in ordinary Korean conversation. Korean prefers to omit pronouns when they are clear.

Korean often puts the condition first and the result second.

Structure:

• 이 길로 가면 = if/when you go this way
• 학교가 나와요 = the school appears / you’ll see the school

So the sentence is literally:

• If you go by this road, the school appears.

This is a very common Korean pattern:

[condition] + [result]

Examples:

• 쭉 가면 은행이 나와요. = If you keep going straight, you’ll see a bank.
• 오른쪽으로 돌면 역이 나와요. = If you turn right, you’ll come to the station.

Not with the same meaning.

Each particle gives a different idea:

• 이 길로 = by this road / along this road / this way
  → focuses on the route or direction

• 이 길을 = this road (object)
  → possible with verbs where the road is treated as the path being traversed, as in 이 길을 가다, though 이 길로 가다 is often more natural for directions

• 이 길에 = on/at this road
  → focuses on location, not route

So for giving directions, 이 길로 가면 is the most natural choice.

Yes, the pattern is very common in directions:

• N(으)로 가면 X가 나와요
• If you go toward/along N, you’ll see X

Very natural examples:

• 앞으로 가면 공원이 나와요. = If you go forward, you’ll see a park.
• 왼쪽으로 가면 화장실이 나와요. = If you go left, you’ll find the restroom.
• 쭉 가면 사거리가 나와요. = If you go straight, you’ll come to an intersection.

So even if 나오다 seems strange at first, this pattern is extremely useful for understanding spoken directions.

나와요 is pronounced roughly like na-wa-yo.

Breakdown:

• 나오다 → stem 나오-
• 나와요 is formed from that verb and contracts naturally

The 오 + 아 combination becomes 와, so:

• 나오아요 → 나와요

This kind of contraction is very common in Korean:

• 오다 → 와요
• 나오다 → 나와요
• 보다 → 봐요
