Přestože výpis z katastru nemovitostí máme, potřebujeme občanský průkaz.

Přestože means although, even though, or despite the fact that. It introduces a subordinate clause that contrasts with the main clause.

So the structure is:

Přestože ... , ... = Although ... , ...

In this sentence, it sets up the contrast:

• we do have the extract
• but we still need an ID card

Do not confuse přestože with přesto, which usually means nevertheless / still / even so.

Yes. All of these can mean although / even though:

• přestože
• i když
• ačkoli / ačkoliv

A few rough tendencies:

• i když is very common and conversational
• přestože is standard and slightly more formal
• ačkoli / ačkoliv can sound a bit more formal or literary

So these are all possible:

• Přestože výpis z katastru nemovitostí máme, potřebujeme občanský průkaz.
• I když máme výpis z katastru nemovitostí, potřebujeme občanský průkaz.
• Ačkoli máme výpis z katastru nemovitostí, potřebujeme občanský průkaz.

This is mainly a matter of word order and emphasis.

A more neutral version would be:

Přestože máme výpis z katastru nemovitostí, potřebujeme občanský průkaz.

The given sentence puts výpis z katastru nemovitostí before máme, which gives that object a bit more emphasis or contrast:

Přestože výpis z katastru nemovitostí máme... = Although we do have the property-register extract...

So this word order is natural, but a little more marked than the neutral máme výpis... order.

Výpis is in the accusative singular, because it is the direct object of máme.

We ask:

Máme co?
výpis

The tricky part is that for many masculine inanimate nouns, the accusative singular looks the same as the nominative singular. That is exactly what happens here:

• nominative: výpis
• accusative: výpis

So the form does not change, but the function does.

Because z means from / out of, and it requires the genitive case.

So:

• katastr → z katastru
• nemovitosti here is also in the genitive: nemovitostí

The phrase katastr nemovitostí is a standard expression meaning the real estate cadastre / land register / property register.

Literally, it is something like:

• katastr = register/cadastre
• nemovitostí = of real estate / of properties

And then:

výpis z katastru nemovitostí = an extract from the real estate cadastre

It means an official extract from the Czech register of real estate ownership and property information.

A natural English translation could be:

• an extract from the land register
• a property register extract
• an extract from the real estate cadastre

Word by word:

• výpis = extract, statement, official printout
• z = from
• katastru nemovitostí = the property/real estate cadastre

So this is not just any list; it is an official administrative document.

Občanský průkaz is in the accusative singular, because it is the direct object of potřebujeme.

We ask:

Potřebujeme co?
občanský průkaz

Again, the form looks the same as the nominative because průkaz is a masculine inanimate noun:

• nominative: občanský průkaz
• accusative: občanský průkaz

The adjective občanský matches the noun in case, gender, and number.

It means an identity card, specifically the standard Czech national ID card.

Literally:

• občanský = civic, citizen-related
• průkaz = card, pass, document, certificate

In real usage, občanský průkaz is the normal term for the official ID card Czech citizens have.

It does not mean just any document. It refers to a specific kind of ID.

Because Czech often omits subject pronouns when they are clear from the verb ending.

Here:

• máme = we have
• potřebujeme = we need

The ending -me already tells you the subject is we, so my is usually unnecessary.

You could add my for emphasis, but in normal sentences it is usually left out.

Because Czech has no articles.

English must choose between:

• a
• the

Czech does not do that grammatically. Instead, definiteness is understood from context.

So:

• výpis can mean an extract or the extract
• občanský průkaz can mean an ID card or the ID card

The situation tells you which interpretation is meant.

Because přestože introduces a subordinate clause, and in Czech subordinate clauses are normally separated by commas.

Here the first part is the subordinate clause:

Přestože výpis z katastru nemovitostí máme

Then comes the main clause:

potřebujeme občanský průkaz

So the comma marks the boundary between them.

If the order were reversed, the comma would come before the subordinate clause:

Potřebujeme občanský průkaz, přestože výpis z katastru nemovitostí máme.

Yes. That version is probably the most neutral in everyday Czech.

Compare the two:

• Přestože máme výpis z katastru nemovitostí, potřebujeme občanský průkaz.
• Přestože výpis z katastru nemovitostí máme, potřebujeme občanský průkaz.

The second one puts more focus on výpis z katastru nemovitostí, almost as if saying:

Although we do have the extract from the property register, we still need an ID card.

So both are correct, but the given sentence has a bit more emphasis.
