일행 means something like the party, the group traveling together, or the people in one’s company. It is often used when talking about people moving together, especially on a trip, outing, or shared journey.

Compared with similar words:

• 그룹 = group, usually a general or borrowed word
• 팀 = team, often for sports, work, or organized roles
• 일행 = a group of people together in the same party, especially in movement or travel

So in this sentence, 우리 일행 suggests our group / the people with us rather than a formal team.

In Korean, 우리 literally means our, but it is often used where English would naturally say my.

For example, Koreans often say:

• 우리 엄마 = my mom
• 우리 집 = my house
• 우리 일행 = our group / the group I’m with

So here, 우리 일행 can mean our group in a literal sense, but depending on context, an English speaker might translate it more naturally as my group or the group I’m with.

The particle 이 is the subject marker. It marks 일행 as the subject of the sentence.

So:

• 우리 일행이 = our group
  • subject marker

This tells you that our group is the thing that fell behind.

You might wonder why it is not 은/는. Using 이/가 often presents the subject more directly as the one doing or experiencing the action. In this sentence, the speaker is simply stating what happened to the group: our group fell a bit behind.

조금 means a little or slightly. It softens the statement.

So:

• 뒤처졌어 = fell behind / got left behind
• 조금 뒤처졌어 = fell behind a little / got a bit behind

It suggests the delay or lag is not very large. In English, this is often translated naturally as a little, a bit, or slightly.

The dictionary form is 뒤처지다, which means to fall behind, to lag behind, or to be left behind.

The form 뒤처졌어 is the past tense casual form:

• 뒤처지다 = to fall behind
• 뒤처졌어 = fell behind / has fallen behind

This comes from combining the verb stem with past tense -었- and the casual ending -어.

Both are possible, but they have different levels of style.

• 뒤처졌어 = casual, conversational
• 뒤처졌다 = plain form, often used in writing, narration, or a more neutral statement

So 우리 일행이 조금 뒤처졌어 sounds like something you would say in conversation to a friend, companion, or someone you speak casually with.

If you wanted a polite version, you could say:

• 우리 일행이 조금 뒤처졌어요.

It can be used both literally and figuratively.

In a literal sense:

• a group walking more slowly than others
• someone lagging behind on a trip

In a figurative sense:

• falling behind in school
• lagging behind in work
• being behind others in progress or development

In this sentence, because 일행 refers to a travel/group context, it most likely means physically falling behind.

Yes. The standard form is 뒤처지다.

Many Koreans say or write 뒤쳐지다, and you will definitely see it in real life, but standard Korean spelling treats 뒤처지다 as correct.

So for learners, it is best to memorize:

• standard: 뒤처지다
• commonly seen/spoken variation: 뒤쳐지다

Yes, very naturally. Because of 우리 일행, the speaker usually sounds like someone belonging to that group.

So the feeling is often:

• the group I’m in fell a little behind
• our party got a bit behind

This is one reason 우리 is so common in Korean. It often places the speaker inside the group or relationship being discussed.

Sometimes, yes, depending on context.

The core meaning of 뒤처지다 is to fall behind or lag behind, but in natural translation, English might sometimes use:

• fell behind
• lagged behind
• got delayed
• was a bit behind

For example, if a tour group is supposed to follow another group and moves more slowly, English might naturally say Our group got a little delayed even though the Korean literally focuses on being behind.

So the best translation depends on the situation, but the Korean image is still basically being behind others.

Here are some common levels:

• Casual: 우리 일행이 조금 뒤처졌어.
• Polite: 우리 일행이 조금 뒤처졌어요.
• More formal/plain written style: 우리 일행이 조금 뒤처졌습니다.

The meaning stays basically the same. Only the speech level changes.

A speaker might say this when:

• walking with a tour group
• hiking with others
• traveling in multiple cars or groups
• moving together through an airport, station, or street
• reporting that their group is not keeping up

For example, someone might say it to explain why they arrived late or why they are not with the others yet:

• 우리 일행이 조금 뒤처졌어. 먼저 가 있어.
  • Our group fell a little behind. Go on ahead.

So the sentence feels very natural in real-life movement or travel situations.
