deungsanro-eseo uri ilhaengeul jamkkan gidarija.

에서 marks the place where an action happens. Since 기다리다 means to wait, and waiting is treated as an action taking place somewhere, 등산로에서 means on/at the hiking trail as the location of the waiting.

A simple way to think about it:

• 에 often marks a destination or location of existence
• 에서 often marks the location where someone does something

So here, 등산로에서 sounds natural because the speaker is saying where the group should wait.

일행 means the people traveling together, one’s party, or companions.

It is often used for a group that is moving together, especially on a trip, outing, hike, tour, etc.

So 우리 일행 is something like:

• our group
• our party
• the people we’re with

It sounds a bit more specific than a general word like group, because it usually implies people accompanying one another.

In Korean, 의 is often omitted in everyday speech when showing possession, especially before nouns like family, group, country, school, and so on.

So:

• 우리 일행 = natural, common
• 우리의 일행 = grammatically possible, but more formal or emphasized

Also, 우리 is used very often in Korean where English might use my or our, depending on context. Here it naturally means our group.

This is a very common learner question. In Korean, 기다리다 directly takes an object, so the person or group being waited for gets 을/를.

So Korean says:

• 일행을 기다리다 = to wait for the group

Even though English uses the preposition for, Korean does not. You should learn 기다리다 as a verb pattern like this:

• N을/를 기다리다 = wait for N

Examples:

• 친구를 기다려요. = I’m waiting for my friend.
• 버스를 기다려요. = I’m waiting for the bus.

잠깐 is an adverb meaning for a moment, briefly, or for a short time.

In this sentence, it tells you that the waiting should only be for a short time.

It modifies the verb 기다리자, so the meaning is basically:

• Let’s wait briefly
• Let’s wait for a moment

Its position is fairly flexible, but putting it before the verb is very common:

• 등산로에서 우리 일행을 잠깐 기다리자.
• 등산로에서 잠깐 우리 일행을 기다리자.

Both are understandable, though the original sounds very natural.

-자 is the propositive ending. It means let’s ... and is used when the speaker is suggesting that they and the listener do something together.

So:

• 기다리자 = let’s wait

This is a casual/plain style. It is commonly used:

• when talking to someone close in age or relationship
• in internal narration
• in a straightforward suggestion

Compare:

• 기다리자 = let’s wait
• 기다립시다 = let’s wait (more formal/polite)
• 기다려라 / 기다려 = wait (command, not let’s)

The subject is omitted, which is very normal in Korean.

Because the verb ends in -자 (let’s), the implied subject is understood as we:

• (우리는) 등산로에서 우리 일행을 잠깐 기다리자.

Korean often leaves out subjects when they are obvious from context or from the verb ending.

So even without saying 우리는, the meaning is clear.

Yes, this can feel slightly strange if you think about it too literally in English.

In Korean, 우리 일행 can refer to the people in our party, and in context it may mean:

• the rest of our group
• the others we are traveling with
• the members of our party who are behind or separated from us

So the speaker may be talking to one or more people who are currently ahead, suggesting they wait for the rest of the party.

If someone wanted to make that idea extra clear, they might say something like:

• 나머지 일행을 기다리자 = let’s wait for the rest of the group

But 우리 일행을 기다리자 is still understandable in context.

Yes. Korean word order is more flexible than English because particles show each word’s role.

The most important thing is that:

• 등산로에서 = location
• 우리 일행을 = object
• 잠깐 = adverb
• 기다리자 = verb

So variations are possible, such as:

• 우리 일행을 등산로에서 잠깐 기다리자.
• 잠깐 등산로에서 우리 일행을 기다리자.

However, the original order sounds natural and easy to process:

• place → object → adverb → verb

That is a very common Korean sentence flow.

It is in the plain/casual style because of -자.

That does not automatically mean rude. It just means it is not marked with politeness like -요 or -ㅂ니다.

This style is natural:

• among close friends
• between equals
• in narration
• in informal planning or discussion

If you wanted a more polite version, you could say:

• 등산로에서 우리 일행을 잠깐 기다립시다.

That means the same thing, but in a more formal/polite way.
