This is just the normal Korean expression for it rains: 비가 오다.

Literally, it looks like rain comes, but you should learn it as one set expression meaning to rain.

• 비 = rain
• 오다 = to come
• 비가 오다 = to rain

Korean often describes weather in ways that do not match English word-for-word, so it is best not to translate it too literally every time.

-기 전에 means before doing something.

It is made like this:

• verb stem + -기 → turns the verb into a noun-like form
• 전에 → before

So:

• 오다 → 오기
• 오기 전에 = before coming
• 비가 오기 전에 = before it rains

This pattern works with many verbs:

• 먹기 전에 = before eating
• 자기 전에 = before sleeping
• 가기 전에 = before going

The 가 is the subject particle.

In 비가 오기 전에, 비가 오다 is the standard way to say it rains. So 비 is treated as the subject of the verb 오다.

• 비 = rain
• 비가 = rain + subject marker
• 비가 오다 = it rains

For learners, the most useful thing is to remember 비가 오다 as the normal expression, rather than trying to rebuild it from English every time.

Because 걷다 is an action happening in the park, and 에서 marks the place where an action happens.

• 공원에서 걷다 = walk in the park

Compare:

• 공원에 가요 = I go to the park
  → 에 marks destination
• 공원에서 걸어요 = I walk in the park
  → 에서 marks location of the action

So in this sentence, the park is not just the destination; it is the place where the walking happens.

조금 means a little or for a bit.

In this sentence, it softens the action and makes it sound like:

• walk a little
• walk for a bit
• take a short walk

So 공원에서 조금 걸을게요 means something like I’ll walk a little in the park or I’ll take a short walk in the park.

-을게요 / -ㄹ게요 is often used when the speaker is expressing:

• a decision they are making now
• an intention
• a promise or assurance to the listener

So 걸을게요 is not just plain future tense. It has a nuance like:

• I’ll walk
• I’ll go for a walk
• I’ll do that

In context, it can sound like the speaker is telling the listener their plan in a friendly, somewhat responsive way.

Compare:

• 걸어요 = I walk / I’m walking / I will walk
• 걸을 거예요 = I’m going to walk / I will walk
• 걸을게요 = I’ll walk (with a nuance of intention or assurance to the listener)

This is because 걷다 is a ㄷ irregular verb.

When ㄷ is followed by a vowel-initial ending, the ㄷ changes to ㄹ.

So:

• dictionary form: 걷다
• stem: 걷-
• before -을게요, the ㄷ changes to ㄹ
• result: 걸을게요

You can see the same pattern in other forms too:

• 걷다 → 걸어요
• 듣다 → 들어요
• 묻다 → 물어요
  though not every ㄷ verb is irregular

So 걸을게요 is the correct conjugation of 걷다.

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

So even though the sentence does not say 저는 or 제가, the meaning is still naturally understood as I’ll walk a little in the park before it rains.

This is very common in Korean. If the speaker is talking about their own action, the subject is often omitted.

You could say:

• 저는 비가 오기 전에 공원에서 조금 걸을게요.

But in many situations, that sounds unnecessary unless you want emphasis or contrast.

Yes. Korean usually puts time and place information before the main verb, and the main verb comes at the end.

Here is the structure:

• 비가 오기 전에 = before it rains
• 공원에서 = in the park
• 조금 = a little / for a bit
• 걸을게요 = I’ll walk

So the sentence is literally closer to:

Before rain comes, in the park, a little, I’ll walk.

That sounds odd in English, but it is normal Korean word order.

Yes, that is a very natural translation.

Even though the Korean uses 걷다 (to walk), English often prefers take a walk or go for a walk in this kind of sentence.

So these are all good translations:

• I’ll walk a little in the park before it rains.
• I’ll take a short walk in the park before it rains.
• I’ll go for a short walk in the park before it rains.

The exact English wording can change, even though the Korean sentence stays the same.
