A bérlő leginkább bútorozott lakást akar.

Here is a word-by-word breakdown:

• A = the
• bérlő = tenant / renter
• leginkább = mostly, above all, most of all, preferably
• bútorozott = furnished
• lakást = apartment / flat with the -t accusative ending
• akar = wants

So the sentence means something like:

• The tenant mostly wants a furnished apartment
• more naturally in English: The tenant primarily wants a furnished apartment or The tenant would prefer a furnished apartment

The -t marks the direct object in Hungarian. This is called the accusative case.

In this sentence, the thing being wanted is lakás (apartment), so it gets -t:

• lakás = apartment
• lakást = apartment (as the direct object)

Compare:

• A bérlő lakást akar. = The tenant wants an apartment.

Hungarian often marks the object directly on the noun, unlike English.

Because Hungarian does not always use articles in the same way English does.

In this sentence:

• A bérlő = the tenant → definite, so it has the article a
• bútorozott lakást = a furnished apartment → indefinite, and Hungarian often leaves the indefinite article egy out when it is not especially important

So:

• bútorozott lakást akar = wants a furnished apartment
• egy bútorozott lakást akar would also be possible, but it would put a bit more emphasis on one / a certain furnished apartment

Omitting egy is very common.

Leginkább literally means most, most of all, primarily, or preferably, depending on context.

In this sentence, it does not mean mathematical the most in a strict sense. It expresses preference:

• A bérlő leginkább bútorozott lakást akar. = The tenant preferably wants a furnished apartment. = What the tenant wants most is a furnished apartment.

So it tells us that, among possible options, a furnished apartment is the preferred one.

Hungarian word order is flexible, but it is strongly connected to focus and emphasis.

This order is natural and neutral enough for saying that the tenant’s main preference is for a furnished apartment.

A rough structure is:

• A bérlő = topic, what the sentence is about
• leginkább bútorozott lakást = the most important information about the preference
• akar = wants

Different word orders can change the emphasis. For example:

• A bérlő bútorozott lakást akar. = The tenant wants a furnished apartment.
  More basic, without explicitly saying preferably / most of all.

• A bérlő leginkább lakást akar. = This would shift the emphasis and sound like What the tenant wants most is an apartment, not something else.

So the placement of leginkább helps show what the preference applies to.

Bútorozott is an adjective meaning furnished.

It is related to bútor (furniture). In Hungarian, many adjectives like this come from verbs or participle-like forms.

So:

• bútor = furniture
• bútorozott = furnished, equipped with furniture

You can use it before a noun:

• bútorozott lakás = furnished apartment

This is a very common real-estate word in Hungarian.

Because in Hungarian, when an adjective comes directly before a noun, the noun usually carries the case ending, not the adjective.

So:

• bútorozott lakás = furnished apartment
• bútorozott lakást = furnished apartment (object)

The -t goes on lakás, not on bútorozott.

This is normal in Hungarian:

• nagy ház = big house
• nagy házat = big house (object)

The adjective stays unchanged in this kind of phrase.

Hungarian has two forms of the definite article:

• a
• az

Which one is used depends on the following sound:

• a before a consonant
• az before a vowel

Since bérlő begins with b, a consonant, we use:

• a bérlő

Compare:

• az ember = the person
• az albérlő = the subtenant

Akar is the third person singular present tense form of the verb akarni (to want).

So:

• akarok = I want
• akarsz = you want
• akar = he/she/it wants

In this sentence, the subject is a bérlő (the tenant), which is third person singular, so akar is the correct form.

Not naturally. This sentence means that the tenant wants a furnished apartment as an object.

That is:

• bútorozott lakást = a furnished apartment

It describes the type of apartment being wanted.

If you wanted to say The tenant wants the apartment to be furnished, Hungarian would normally use a different structure, not this one.

So here, bútorozott is simply modifying lakást.

Usually yes, in this context.

Lakás commonly means:

• apartment
• flat

depending on the variety of English.

So:

• bútorozott lakás = furnished apartment in American English
• furnished flat in British English

The exact translation can vary, but the Hungarian word is very standard for an apartment/home unit.

Yes, it would be correct.

• A bérlő leginkább bútorozott lakást akar.
• A bérlő leginkább egy bútorozott lakást akar.

Both are grammatical. The version without egy is often more natural in Hungarian when you just mean a furnished apartment in a general sense.

Adding egy can make it feel a bit more specific or a bit more explicitly indefinite, somewhat like stressing one or a certain furnished apartment, depending on context.

So the original sentence is perfectly normal.
