A felújított lakás üres, mintha bútorozatlan lenne.

In Hungarian, the verb van = to be is usually left out in the present tense, third person singular and plural, when you are simply saying that something is something or is in some state.

So:

• A lakás üres = The apartment is empty
• not normally A lakás van üres

This is completely normal Hungarian.

But in the second part, lenne appears because that is not the plain present-tense form. It is the conditional form of van, and conditional forms are not omitted.

Felújított is the past participle of felújít, which means to renovate or to refurbish.

So:

• felújít = to renovate
• felújított = renovated / refurbished

In this sentence, it works like an adjective modifying lakás:

• felújított lakás = renovated apartment

This is a very common Hungarian pattern: a past participle can be used directly before a noun as an adjective.

Yes. A is the definite article, meaning the.

Hungarian has two forms of the definite article:

• a before consonant sounds
• az before vowel sounds

So:

• a lakás = the apartment
• az épület = the building

Here, lakás begins with a consonant, so Hungarian uses a.

At the beginning of the sentence, it is capitalized as A.

Mintha means as if or as though.

It introduces a comparison that describes how something seems, not necessarily what is actually true.

So:

• A lakás üres, mintha bútorozatlan lenne
  = The apartment is empty, as if it were unfurnished

The idea is that the apartment looks or feels so empty that it gives the impression of being unfurnished.

After mintha, Hungarian very often uses the conditional form of the verb.

Here:

• lenne = would be / were
• it is the conditional form of van

So:

• mintha bútorozatlan lenne = as if it were unfurnished

This is one of the most important things to notice in the sentence. English often uses were in this kind of unreal comparison, while Hungarian uses the conditional.

A useful pattern to remember is:

• mintha + conditional

They are related, but not identical.

• üres = empty
• bútorozatlan = unfurnished

So an apartment can be:

• üres if there is nothing in it, or almost nothing in it
• bútorozatlan if it has no furniture

In this sentence, the speaker says the apartment is empty, and then adds that it is so empty that it seems as if it were unfurnished.

So the second part strengthens or clarifies the first part.

It comes from bútor, meaning furniture, and the verb bútoroz, meaning to furnish.

From that, Hungarian forms:

• bútorozott = furnished
• bútorozatlan = unfurnished

So bútorozatlan is an adjective meaning that something has not been furnished, or has no furniture.

This kind of word formation is very common in Hungarian, where a derived adjective can express the idea of lacking something or not having been affected by an action.

Because mintha bútorozatlan lenne is a subordinate clause.

Hungarian normally separates subordinate clauses with a comma, especially when they are introduced by words like:

• hogy = that
• mert = because
• ha = if
• mintha = as if

So the comma here is standard and expected.

The given word order is natural and neutral:

• A felújított lakás üres, mintha bútorozatlan lenne.

But Hungarian word order is fairly flexible, and changing it can shift the emphasis.

For example:

• Üres a felújított lakás puts more emphasis on üres
• A lakás felújított would mean something different, focusing on the fact that it has been renovated

So the exact order used here presents the apartment first, then states its condition in a straightforward way.

Lakás most commonly means apartment or flat, but more broadly it can also mean a dwelling or residence depending on context.

In everyday usage, though, an English speaker will most often understand it as:

• apartment
• flat

If Hungarian wants to say house, it usually uses ház instead.

So:

• lakás = apartment / flat
• ház = house

In this sentence, apartment is the most natural translation.
