Policista chce vidět platný pas.

Because policista is a masculine noun of a special type: it refers to a male person, but its form looks a bit like a feminine noun because it ends in -a.

Czech has several masculine nouns like this, especially for professions or people, for example:

• kolega = colleague
• turista = tourist
• taxikář is different, but taxikářka etc. show how profession words vary

So even though policista ends in -a, it is still grammatically masculine when it refers to a man.

Its feminine counterpart is policistka.

Here pas is in the accusative singular, because it is the direct object of vidět (to see).

The important point is that pas is a masculine inanimate noun, and in Czech, many masculine inanimate nouns have:

• nominative singular: pas
• accusative singular: pas

So the form does not change here.

That is why:

• To je pas. = That is a passport.
• Vidím pas. = I see a passport.

Same form, different case function.

Platný agrees with pas in:

• gender: masculine
• number: singular
• case: accusative

Since pas is masculine inanimate singular, the adjective takes the matching form platný.

So:

• platný pas = valid passport

For masculine inanimate nouns, the accusative singular adjective is often the same as the nominative singular:

• platný pas
• nový stůl
• český film

If the noun were different, the adjective would change too. For example:

• platná karta = valid card
• platné vízum = valid visa

This is a very common Czech pattern:

• chtít
  • infinitive

It works much like English to want to do something.

So:

• chce = wants
• vidět = to see

Together:

• chce vidět = wants to see

Other examples:

• Chci jít. = I want to go.
• Chce spát. = He/She wants to sleep.
• Chceme odejít. = We want to leave.

So the sentence uses a very standard verb + infinitive construction.

Vidět means to see, and here it is used in the sense of wanting to see / inspect / check the passport.

In real-life contexts, especially with officials, Czech often uses vidět where English might also say:

• see
• look at
• check

So Policista chce vidět platný pas is natural Czech.

Also, vidět is the imperfective verb. Its perfective partner is uvidět. In this sentence, the imperfective is normal because after chtít Czech usually uses the basic infinitive naturally:

• chce vidět = wants to see

Because Czech has no articles.

English distinguishes:

• a passport
• the passport

Czech usually does not mark that directly with a separate word. Context tells you whether something is definite or indefinite.

So platný pas could mean:

• a valid passport
• the valid passport

depending on the situation.

This is very normal in Czech, and learners have to get used to relying more on context.

Czech word order is much more flexible than English word order, because case endings help show the grammatical roles.

The sentence:

• Policista chce vidět platný pas.

is the most neutral, straightforward order.

But other orders are possible, for example:

• Platný pas chce policista vidět.
• Policista platný pas chce vidět.

These alternatives may sound more marked, more emphatic, or more context-dependent.

As a learner, it is best to treat:

• subject + verb + infinitive + object

as the safest neutral pattern here.

Because in normal Czech, descriptive adjectives usually come before the noun, just like in English.

So:

• platný pas = valid passport
• nový dům = new house
• české auto = Czech car

Putting the adjective after the noun is possible in some special styles or expressions, but it is not the normal neutral pattern here.

So platný pas is exactly what you would expect in standard Czech word order inside the noun phrase.

Yes, chce is a word many learners notice.

It is pronounced approximately like:

• kh-tseh

More precisely, the ch in Czech is a separate sound, like the ch in German Bach or Scottish loch, not like English ch in chair.

Then ce sounds like tse.

So chce comes out roughly as:

• [x-tse]

The whole sentence has stress on the first syllable of each word, because Czech stress is usually initial:

• PO-licista
• CHCE
• VI-dět
• PLAT-ný
• PAS

Vidět is an infinitive, the basic dictionary form of the verb.

In Czech, after verbs like chtít (to want), you normally use the infinitive:

• chci vidět = I want to see
• chce vidět = he/she wants to see
• chtějí vidět = they want to see

So in this sentence:

• chce is the finite verb
• vidět is the infinitive depending on chce

This is very similar to English wants to see, except Czech does not need a separate word like to before the infinitive in this construction.

Yes. Policista specifically means a male police officer / policeman. If you want the female form, use:

• policistka = female police officer / policewoman

Sometimes Czech also uses more formal or institutional phrasing depending on context, but policista is a normal everyday word.

So this sentence is specifically about a male officer. If the officer were female, it would be:

• Policistka chce vidět platný pas.

Because Czech often leaves out subject pronouns when they are unnecessary.

In this sentence, the subject is already clearly given as policista, so there is no reason to add a pronoun.

Even when there is no noun, Czech often omits the pronoun because the verb ending already helps identify the person:

• Chci vidět pas. = I want to see a passport.
• Chce vidět pas. = He/She wants to see a passport.

So Czech is much less dependent on subject pronouns than English.

Its main meaning here is valid, especially for documents, tickets, laws, rules, and official things.

Common examples:

• platný pas = valid passport
• platná jízdenka = valid ticket
• platný zákon = valid law / law in force

It comes from the verb platit, which can mean things like to be valid or to apply, and also to pay in other contexts.

So learners often notice that this word family covers more than one English idea, but in platný pas, the meaning is clearly valid passport.
