다른 means different, another, or other, depending on context.

It comes from the dictionary form 다르다, which means to be different.
When Korean descriptive verbs modify a noun directly, they often change form. So:

• 다르다 → 다른 팀
• literally: a different team / another team / the other team

In this sentence, 다른 팀 means something like another team or a different team.

This is about the difference between the topic marker 은/는 and the subject marker 이/가.

• 팀은 = as for the team / the team,
• 팀이 = marks the team more directly as the grammatical subject

Using 은 often gives a sense of:

• introducing a topic
• contrast
• talking about something already known in the conversation

So 다른 팀은 산책로를 확인했습니다 can feel like:

• As for the other team, they checked the trail.
• possibly with a contrast like our team did something else

If you said 다른 팀이 산책로를 확인했습니다, it would sound more like:

• It was the other team that checked the trail
• or simply a more neutral subject-focused statement

Both can be correct, but 은 adds a topic/contrast nuance.

-은 is the topic particle. It attaches to nouns that end in a consonant.

• 팀 ends in a consonant sound, so it takes 은
• if the noun ended in a vowel, you would use 는

Examples:

• 팀은
• 학교는

In this sentence, 팀은 means as for the team or simply marks the team as the topic being discussed.

를 is the object marker.

In this sentence:

• 산책로를 = the walking trail as the thing being checked

The verb 확인했습니다 means checked / confirmed / inspected, and the thing being checked is the object, so it takes 를.

Structure:

• 다른 팀은 = topic
• 산책로를 = object
• 확인했습니다 = verb

Here, 로 is not a particle.
산책로 is a single noun meaning walking path, trail, or promenade.

It is made from:

• 산책 = walk, stroll
• 로 = road/path, as part of a noun

So 산책로 is a compound noun.

This is different from the particle -(으)로, which can mean things like to, by, or as in other sentences. In 산책로, it is just part of the vocabulary word.

확인했습니다 comes from:

• 확인하다 = to check, confirm, verify

This verb is built from:

• 확인 = confirmation/check
• 하다 = to do

So:

• 확인하다 literally = to do a check / to confirm

Then it is conjugated into the past formal polite form:

• 확인하다 → 확인했습니다

That means:

• checked
• confirmed
• verified

depending on context.

확인했습니다 is:

• past tense
• formal polite style (also called deferential style)

This style is common in:

• announcements
• reports
• presentations
• workplace speech
• news
• polite written narration

Compare:

• 확인했습니다 = formal polite past
• 확인했어요 = polite casual past
• 확인했다 = plain form past

So this sentence sounds appropriately formal, not casual.

Korean normally uses Subject/Object/Verb order, with the verb coming at the end.

So this sentence is structured like:

• 다른 팀은 = the other team
• 산책로를 = the trail
• 확인했습니다 = checked

Literally, it is closer to:

• The other team the trail checked

This is normal in Korean. The final verb carries important information such as:

• tense
• politeness
• sentence type

That is why Korean learners often need to wait until the end of the sentence to get the full action.

In conversational Korean, particles are often omitted when the meaning is obvious. But in a clear, careful sentence like this, keeping them is very natural.

For example:

• 다른 팀은 산책로를 확인했습니다 = complete and clear
• 다른 팀 산책로 확인했습니다 = possible in very casual or note-like contexts, but less standard

So for learners, it is best to understand and use the full version first:

• 은/는 for topic
• 을/를 for object

Yes, it often can.

Because 은 can create contrast, 다른 팀은 may imply something like:

• As for the other team, they checked the trail
• maybe while our team did something else
• or while another group handled a different task

The sentence does not always require a direct comparison, but the contrastive feeling is possible and very common.

So this could sound like part of a larger discussion, for example:

• 우리 팀은 장비를 준비했고, 다른 팀은 산책로를 확인했습니다.
• Our team prepared the equipment, and the other team checked the trail.

The spelling is 확인했습니다, but the actual pronunciation is a bit smoother than a letter-by-letter reading.

A common pronunciation is close to:

• 화긴해씀니다

Some sound changes happen naturally in speech:

• 확인 often sounds closer to 화긴
• 했습니다 often sounds closer to 해씀니다

You do not need to overthink every sound change at first, but it is useful to know that spoken Korean often sounds slightly different from the spelling.

Yes. Depending on context, 확인하다 can mean:

• check
• confirm
• verify
• inspect

So 산책로를 확인했습니다 could mean:

• they checked the trail
• they inspected the trail
• they confirmed the trail’s condition

The best English translation depends on the situation. If this is about safety, preparation, or logistics, checked or inspected may fit especially well.
