아무도 means anyone / nobody, but it normally appears with a negative verb.

So in 지금 집에 아무도 없어요, the combination of:

• 아무도 = anyone
• 없어요 = is not / there is not / do not have

gives the meaning There is nobody at home right now.

A very important pattern is:

• 아무도 + negative verb

Examples:

• 아무도 안 와요. = Nobody comes.
• 아무도 몰라요. = Nobody knows.
• 아무도 없어요. = There is nobody.

So even though 아무도 can look like anyone, in a negative sentence it naturally becomes no one / nobody in English.

In this sentence, 도 adds the meaning of even and is part of the common negative expression 아무도.

So:

• 아무 = any
• 도 = even / also

Together in negative sentences, 아무도 means not even one person → nobody.

That is why you usually learn it as a fixed form:

• 아무도 없어요
• 아무도 안 왔어요
• 아무도 몰라요

You generally do not say 아무가 or 아무는 in this meaning.

집에 means at home or to home, depending on context. Here it means at home.

• 집 = house / home
• 에 = location marker or destination marker

In this sentence, 에 marks the place where someone is or is not:

• 집에 있어요 = is at home
• 집에 없어요 = is not at home

So 지금 집에 아무도 없어요 literally has the structure:

• 지금 = now
• 집에 = at home
• 아무도 = anybody / nobody
• 없어요 = is not / there is not

Korean word order is often different from English. Korean usually puts the verb at the end.

English:

• Nobody is at home right now.

Korean:

• 지금 집에 아무도 없어요.
• literally: now / at home / nobody / is not

This is normal in Korean. Time expressions like 지금 often come near the beginning, and the verb comes last.

So even if the order feels unusual, it is following standard Korean sentence structure.

없어요 is the natural opposite of 있어요.

• 있어요 = there is / to exist / to be present
• 없어요 = there is not / to not exist / to be absent

So:

• 집에 있어요 = is at home
• 집에 없어요 = is not at home

You can sometimes hear negative forms with 안, but for 있다, Korean very commonly uses the separate opposite verb 없다 instead of 안 있다.

That is why 아무도 없어요 is the natural expression, not 아무도 안 있어요.

없어요 is the polite informal style, often called the -요 form.

It is appropriate in many everyday situations:

• speaking to strangers
• speaking politely to coworkers
• general conversation
• classroom examples

Related forms:

• 없습니다 = more formal
• 없어 = casual, used with close friends or younger people

So the same sentence can appear as:

• 지금 집에 아무도 없어요. = polite everyday speech
• 지금 집에 아무도 없습니다. = formal
• 지금 집에 아무도 없어. = casual

Yes. Korean often leaves out the subject when it is obvious from context.

In English, you might expect:

• There is nobody at home right now.
• Nobody is at home right now.

Korean does not need to state a subject like there. The sentence simply describes the situation.

So 지금 집에 아무도 없어요 is complete by itself, even without an explicit subject.

Yes, 지금 is fairly flexible.

These are all possible, though some may sound more natural depending on context:

• 지금 집에 아무도 없어요.
• 집에 지금 아무도 없어요.
• 집에 아무도 지금 없어요. ← less common unless emphasizing right now

The most natural neutral version is usually:

• 지금 집에 아무도 없어요.

Putting 지금 earlier in the sentence is common because time expressions often come near the beginning.

Adding 는 creates contrast or emphasis.

• 집에 아무도 없어요. = There is nobody at home.
• 집에는 아무도 없어요. = At home, there is nobody. / There is nobody at home, though maybe elsewhere there is.

So 집에는 can suggest contrast, such as:

• nobody is at home, but maybe someone is at the office
• at least as for home, it is empty

Without 는, the sentence is more neutral and straightforward.

No. In this sentence, 집에 means at home, not has a house.

That is because:

• 에 marks a location
• 없어요 here describes absence from that location

To say nobody has a house, Korean would need a different structure, such as one involving possession, not just location.

So 지금 집에 아무도 없어요 only means There is nobody at home right now.

Korean verbs do not change for singular vs. plural the way English does.

So 없어요 works whether the meaning is:

• one person is not there
• no people are there
• nothing is there

Examples:

• 사람이 없어요. = There is no person / There are no people.
• 아무도 없어요. = Nobody is there.
• 물이 없어요. = There is no water.

The verb form stays the same.

Yes, but the meaning changes slightly.

• 지금 집에 아무도 없어요. = There is nobody at home right now.
• 지금 집에 사람이 없어요. = There are no people at home right now.

These are very similar, but 아무도 없어요 feels especially natural for nobody is there, with a stronger sense of not even one person.

So both are possible, but 아무도 없어요 is a very common and natural expression.

You change the ending on 없다.

Casual:

• 지금 집에 아무도 없어.

Polite:

• 지금 집에 아무도 없어요.

Formal:

• 지금 집에 아무도 없습니다.

The rest of the sentence can stay the same. The main change is the verb ending.
