Nájemce má možnost reklamovat vyúčtování.

Yes. Nájemce is a masculine animate noun, even though its dictionary form ends in -e.

This is not unusual in Czech. Some masculine nouns referring to people have this pattern, especially in formal or legal vocabulary.

In this sentence, nájemce is in the nominative singular, because it is the subject of the sentence.

A learner may expect a form like nájemník, but nájemce is a more formal/official word for tenant.

Both can refer to a tenant, but the tone is different:

• nájemce = more formal, common in legal, administrative, or contractual language
• nájemník = more everyday/common in normal speech

So in a sentence about rights, billing, or official procedures, nájemce sounds very natural.

Both are possible, but they are not exactly the same in tone.

• má možnost reklamovat = has the possibility / has the right / has the option to contest
• může reklamovat = can contest / may contest

The version with má možnost sounds a bit more formal and often appears in official or legal-style language. It can suggest that the tenant is given an available option under some rules or procedure.

So:

• Nájemce může reklamovat vyúčtování. = simpler, more direct
• Nájemce má možnost reklamovat vyúčtování. = slightly more formal, more bureaucratic

Because after mít možnost (to have the possibility/opportunity), Czech normally uses an infinitive.

The structure is:

• mít možnost + infinitive

Examples:

• Má možnost odejít. = He/She has the option to leave.
• Má možnost se zeptat. = He/She has the opportunity to ask.
• Nájemce má možnost reklamovat vyúčtování.

This is very similar to English to have the possibility to do something or to be able to do something.

No. This is a very important false friend for English speakers.

In Czech, reklamovat usually means:

• to complain about
• to claim against
• to contest
• to make a formal complaint about a faulty product or an incorrect charge

It does not normally mean to advertise in this kind of sentence.

Here it means that the tenant can formally challenge the billing/statement if there is a problem.

Here vyúčtování is in the accusative singular, because it is the direct object of reklamovat.

However, the form looks the same as the nominative:

• nominative singular: vyúčtování
• accusative singular: vyúčtování

That is because vyúčtování is a neuter noun, and many neuter nouns have identical nominative and accusative singular forms.

So even though the case changes functionally, the word itself does not visibly change here.

Vyúčtování is a formal noun meaning something like:

• a billing statement
• a settlement of charges
• an itemized statement
• often a yearly statement of costs, utilities, services, etc.

In housing contexts, it often refers to the final calculation of payments such as heating, water, or other service charges.

So this is a very typical administrative/legal word.

It is definitely on the formal/administrative side.

Why it sounds formal:

• nájemce instead of the more everyday nájemník
• má možnost instead of the simpler může
• vyúčtování is also typical official vocabulary
• reklamovat in this sense is common in legal/consumer/administrative contexts

A more everyday version might be something like:

• Nájemník může napadnout vyúčtování.
• Nájemník si může na vyúčtování stěžovat.

But the original sentence is perfectly natural in official writing.

Yes. Czech word order is flexible, but changing it changes the emphasis.

The neutral order here is:

• Nájemce má možnost reklamovat vyúčtování.

This presents the information in a normal, straightforward way.

Other orders are possible, for example:

• Vyúčtování má nájemce možnost reklamovat.
  This puts more emphasis on vyúčtování.

• Možnost reklamovat vyúčtování má nájemce.
  This emphasizes the possibility itself, and can sound more contrastive or formal.

So the original order is probably the most neutral and natural in standard official prose.

In this sentence, reklamovat is the normal choice.

The verb is typically treated as imperfective in this kind of general statement about a person’s right or option to do something. The sentence is not focusing on one completed act, but on the general possibility.

That is why the infinitive reklamovat works well after má možnost.

For learners, the important point is: after expressions like má možnost, Czech often uses the basic infinitive to describe the available action in general.

A few useful pronunciation points:

• Czech stress is almost always on the first syllable of each word.
• So you get:
  • NÁ-jemce
  • MÁ
  • MOŽ-nost
  • re-kla-MO-vat? No—stress is still on the first syllable: RE-klamovat
  • VY-účtování

A rough pronunciation guide:

• nájemce ≈ NAA-yem-tseh
• má možnost ≈ maa MOZH-nost
• reklamovat ≈ RE-klah-moh-vaht
• vyúčtování ≈ VY-ooch-toh-vaa-nee

Two sounds English speakers often need to watch:

• á = long a
• č = ch as in check
• ž = the sound in measure

Sometimes, but it would not mean exactly the same thing.

• reklamovat vyúčtování = to formally contest/challenge the billing statement
• stěžovat si na vyúčtování = to complain about the billing statement

The second version sounds less technical and less legal. It can describe dissatisfaction, but not necessarily a formal claim procedure.

So in official language, reklamovat vyúčtování is more precise.
