Хозяин дома уже здесь.

In Russian, the present-tense verb to be is usually omitted.

So where English says:

The owner of the house is already here

Russian simply says:

Хозяин дома уже здесь.

Literally, it is closer to:

Owner of-the-house already here.

This is completely normal in Russian.

Хозяин is in the nominative singular. It is the subject of the sentence — the person being talked about.

This is also the dictionary form of the word.

Here дома is the genitive singular form of дом.

It depends on хозяин:

хозяин дома = owner/master/host of the house

Russian often uses the genitive after a noun to show a relationship like of the house, of the school, of the company, and so on.

Compare:

• директор школы = director of the school
• конец фильма = end of the film
• хозяин дома = owner/master of the house

No. In this sentence, дома does not mean at home.

Here it is the noun form of the house.

This is a very common learner confusion, because дома can be:

• an adverb meaning at home
• a noun form of дом

In Хозяин дома уже здесь, it is part of the phrase хозяин дома, so the meaning is owner/master of the house, not owner at home.

No, not in this sentence.

дома can also be the plural form houses, but that reading does not fit here.

In Хозяин дома уже здесь, the natural interpretation is:

• хозяин = the main noun
• дома = of the house

So this is a genitive construction, not a plural noun meaning houses.

Хозяин is a flexible word. Depending on context, it can mean:

• owner
• master
• host
• proprietor
• head of the household

In this sentence, it most naturally means something like the owner/master/host of the house.

It is broader than any single English word, so the best translation depends on context.

A useful related word is:

• хозяйка = the feminine form

Yes, Russian word order is fairly flexible, but the word order in this sentence is a very natural, neutral one.

It starts with the person being talked about:

Хозяин дома

and then gives the information about his presence/location:

уже здесь

You can move words around in Russian, but that usually changes emphasis, tone, or what sounds most natural in context. For a learner, this sentence is a good standard model.

Уже means already.

It shows that the situation is now true, often earlier than expected or earlier than some previous moment.

So the sentence suggests something like:

• he has arrived
• he is here now
• this is no longer pending

In other words, уже adds the idea of already now.

Both здесь and тут can mean here.

The difference is mostly one of style and tone:

• здесь = a bit more neutral and standard
• тут = often a bit more conversational

In many everyday situations, they are interchangeable. In this sentence, здесь sounds perfectly natural and neutral.

Russian has no articles, so there is no separate word for the or a.

You decide from context.

In this sentence, English usually uses the:

the owner of the house

because the person sounds specific and identifiable.

Russian leaves that to context instead of marking it with an article.

Здесь is a short, one-syllable word that many learners find tricky.

A rough guide is:

zdyes'

A few points:

• the ь does not have its own sound
• it softens the final consonant
• the word is pronounced as one compact syllable

It is best learned by listening to native audio a few times and repeating it slowly.
