-가 is the subject marker. It marks 구급차 as the thing doing the action.

So in this sentence:

• 구급차가 = the ambulance as the subject
• 사람을 = the injured person as the object

A learner often compares -가/-이 with -은/-는:

• 구급차가 sounds like the ambulance is the one that...
• 구급차는 would make ambulance the topic, often with a contrast or topic-setting feeling

In this sentence, -가 is the most straightforward choice.

현장 means the scene or the site. In this context, it usually means the scene of the accident/emergency.

-에서 often marks:

• the place where an action happens
• sometimes the place something starts from in context

So 현장에서 here means something like:

• at the scene
• or more naturally in English, from the scene

It is not just a static location marker. It tells you the ambulance is taking the injured person away starting there.

Compare:

• 현장에 = to the scene / at the scene depending on context
• 현장에서 = at/from the scene, where the action is happening

In Korean, words that describe a noun usually come before the noun.

So:

• 다친 사람 = injured person
• more literally, person who got hurt

The word 다친 comes from 다치다 (to get hurt / to be injured). Here it is in a noun-modifying form.

This is very common in Korean:

• 먹는 사람 = person who is eating
• 간 사람 = person who went
• 다친 사람 = person who got hurt / injured person

So instead of saying something after the noun like English sometimes does, Korean puts the modifier before it.

다치다 is the dictionary form, meaning to get hurt.

To modify a noun in a past/completed sense, Korean changes the verb into an adnominal form. For 다치다, that becomes 다친.

So:

• 다치다 = to get hurt
• 다친 사람 = the person who got hurt / injured person

You do not say 다치다 사람. The verb has to change form before a noun.

This pattern is very important in Korean because it is how relative-clause-like meanings are often made.

-을/-를 is the object marker. It marks the direct object of the verb.

Here, the verb is 데려가요 (takes [someone] away / takes [someone] to...), and the person being taken is 사람.

So:

• 사람을 = the person is the object
• 병원에 = the hospital is the destination
• 데려가요 = takes

This tells you clearly that the ambulance is taking the injured person, not that the injured person is doing the taking.

Both can work, but 병원에 is very natural with 데려가다.

Here, -에 marks the destination:

• 병원에 데려가요 = takes [someone] to the hospital

You could also hear:

• 병원으로 데려가요

That also means to the hospital, but -으로 can feel a little more directional, like toward/to. In many everyday sentences, both are possible, but -에 is extremely common for destinations with verbs like 가다, 오다, and 데려가다.

가요 means goes.

데려가요 means takes someone along / takes someone away / takes someone to a place.

So:

• 구급차가 병원에 가요 = The ambulance goes to the hospital.
• 구급차가 사람을 병원에 데려가요 = The ambulance takes the person to the hospital.

The important difference is that 데려가다 includes the idea of bringing or escorting a person/animal somewhere.

It is used for taking people, not just moving yourself.

They are very close.

• 데려가요
• 데리고 가요

Both can mean takes someone along / takes someone to...

In many situations, they are interchangeable. For a learner, it is enough to know that both are common and natural.

Very roughly:

• 데려가다 is a set verb meaning to take someone along
• 데리고 가다 is built from 데리다
  • -고 가다, literally something like take and go with

In everyday speech, the difference is usually not something beginners need to worry much about.

Yes, 데려가요 is in the present polite form, but Korean present tense is broader than English simple present.

Depending on context, it can mean:

• a general fact or usual action
• an action happening now
• a vivid description in a narrative
• sometimes even a near-future meaning

So this sentence could be understood as:

• a general statement about what ambulances do
• or a present-situation description, like in a news report or explanation

Korean often relies on context more than English does for exact time interpretation.

데려가요 is in the polite informal style, often called 해요체.

That means it is:

• polite
• natural in everyday conversation
• very commonly used

Related forms would be:

• 데려갑니다 = more formal/polite, often used in announcements or formal reports
• 데려가 = casual/plain intimate speech
• 데려간다 = plain dictionary-style or narrative style depending on context

So 데려가요 is a very normal, useful everyday form.

Korean does not use articles like English the and an/a.

So nouns like:

• 구급차
• 사람
• 병원

do not need separate words for definiteness. Context tells you whether the meaning is:

• an ambulance or the ambulance
• an injured person or the injured person
• a hospital or the hospital

When translating into English, you choose the most natural article from context.

The order can change more than in English because Korean uses particles to show each word’s role.

This sentence has a very natural order:

• 구급차가 — subject
• 현장에서 — location/source
• 다친 사람을 — object
• 병원에 — destination
• 데려가요 — verb

Because of the particles, Korean can move some parts around for emphasis, as long as the verb stays near the end. For example, 병원에 could appear earlier.

However, one thing does stay fixed:

• 다친 must come before 사람

So Korean word order is flexible, but not completely free.

Yes. Korean often omits subjects when they are clear from context.

So if everyone already knows you are talking about the ambulance, you might just say:

• 현장에서 다친 사람을 병원에 데려가요.

This is perfectly normal Korean.

Korean commonly leaves out:

• subjects
• objects
• other information

when the listener can understand them from context. That is one reason Korean sentences can look shorter or less explicit than English ones.
