가 is the subject marker. It tells you that 자동차 is the thing doing the action.

So:

• 자동차 = car / automobile
• 가 = subject marker

Together, 자동차가 means something like the car as the subject of the sentence.

In this sentence, the car is the thing that moves.

Both can be possible, but they give slightly different nuances.

• 자동차가 천천히 움직입니다.
  This simply points out that the car is the one moving slowly.
• 자동차는 천천히 움직입니다.
  This makes the car the topic, and can sound more like as for the car, it moves slowly or may imply contrast.

A simple way to think about it:

• 가 = focuses on the subject
• 는 = introduces or emphasizes the topic, often with contrast

For beginners, it is enough to understand that 가 is very natural here.

천천히 is an adverb, and it means slowly.

It modifies the verb 움직입니다 (moves / is moving), just like slowly modifies moves in English.

So:

• 천천히 = slowly

It tells you how the car is moving.

움직입니다 is the formal polite present-tense form of the verb 움직이다, which means to move.

Breakdown:

• 움직이다 = dictionary form, to move
• 움직입니다 = formal polite form, often used in:
  • announcements
  • presentations
  • news
  • polite public speech
  • textbook example sentences

So this sentence sounds polite and neutral.

It can mean both, depending on context.

Korean present tense often covers meanings that English separates into:

• moves
• is moving

So 자동차가 천천히 움직입니다 could mean:

• The car moves slowly.
• The car is moving slowly.

Context tells you which one is more natural.

Because Korean normally puts the verb at the end.

A very common Korean word order is:

• Subject + adverb + verb

So here you get:

• 자동차가 = the car
• 천천히 = slowly
• 움직입니다 = moves / is moving

This is different from English, but it is one of the most basic patterns in Korean.

No. 움직이다 is usually an intransitive verb, meaning it does not need a direct object here.

The sentence is complete with just:

• the subject: 자동차가
• the manner adverb: 천천히
• the verb: 움직입니다

In other words, the car simply moves. It is not moving something else.

Yes, very often in Korean, if the subject is already clear from context.

So in a real conversation, someone might simply say:

• 천천히 움직입니다.

This could mean It moves slowly or It is moving slowly, if everyone already knows what it is.

Korean often drops subjects when they are understood.

Korean does not have articles like a and the.

So 자동차 can mean:

• a car
• the car
• sometimes just car / cars in a general sense

The exact meaning depends on context.

That means 자동차가 천천히 움직입니다 could be interpreted as:

• The car is moving slowly
• A car is moving slowly

depending on the situation.

A careful pronunciation is close to:

• ja-dong-cha-ga cheon-cheon-hi um-jik-im-ni-da

In natural Korean pronunciation, 움직입니다 is often heard more like:

• 움지김니다

This happens because Korean pronunciation changes slightly in connected speech.

For a learner, the most important thing is:

• recognize the spelling: 움직입니다
• know the base verb: 움직이다
• get used to hearing the natural spoken form over time

You can do a rough word-for-word breakdown, but the natural English translation may vary.

Rough breakdown:

• 자동차가 = the car / a car
• 천천히 = slowly
• 움직입니다 = moves / is moving

So a literal-style gloss is:

• Car + subject marker + slowly + moves

But natural English would be:

• The car moves slowly.
• The car is moving slowly.

So yes, a word-for-word breakdown is useful for learning structure, but the best English translation depends on context.
