Chci reklamovat vyúčtování.

Chci means I want.

In Czech, after chtít (to want), you normally use the infinitive of another verb directly:

• Chci reklamovat = I want to dispute / complain about
• Chci odejít = I want to leave
• Chci zaplatit = I want to pay

Unlike English, Czech does not need a separate word like to before the second verb in this structure.

This is a very common point of confusion.

In Czech, reklamovat usually means to make a complaint about a product or service, to file a claim, or to dispute something officially.

So in this sentence, reklamovat vyúčtování means something like:

• to dispute the billing
• to challenge the statement
• to make a complaint about the bill

It is not the normal verb for to advertise.

Related words:

• reklama = advertisement
• reklamace = complaint / claim / warranty claim
• reklamovat = to complain about / claim against

So this is a classic false friend for English speakers.

Vyúčtování is a noun meaning something like:

• billing statement
• settlement of charges
• account statement
• itemized bill

The exact English translation depends on context.

For example, it can refer to:

• a utility bill settlement
• a phone bill statement
• a financial accounting of charges
• a final calculation of what is owed

So the sentence is about disputing some kind of statement of charges, not necessarily a simple shop receipt.

Vyúčtování is the direct object of reklamovat, so it is in the accusative case.

However, for many neuter nouns in Czech, the nominative and accusative singular look the same. That is what happens here.

So:

• nominative: vyúčtování
• accusative: vyúčtování

The case is different in function, but the form does not change.

The neutral word order is:

• Chci reklamovat vyúčtování.

That is a very natural, standard way to say it.

Czech word order is flexible, so you could also move things around for emphasis:

• Vyúčtování chci reklamovat.
  = It is the billing statement that I want to dispute.

• Reklamovat chci vyúčtování.
  = Less neutral; sounds more contrastive or emphatic.

For a learner, the original order is the safest and most natural choice.

It is understandable, but it sounds fairly direct.

If you want to sound more polite in a customer-service situation, Czech often uses a softer form:

• Chtěl bych reklamovat vyúčtování.
  = I would like to dispute the billing. (said by a man)

• Chtěla bych reklamovat vyúčtování.
  = same, (said by a woman)

This is often more natural in formal interaction than the plain Chci..., which can sound a bit blunt depending on tone and context.

They are related, but not the same.

• reklamovat = to make a formal complaint/claim about a product, service, bill, or charge
• stěžovat si = to complain in general

So:

• Chci reklamovat vyúčtování.
  = I want to formally dispute the billing.

• Chci si stěžovat na vyúčtování.
  = I want to complain about the billing.

The second one sounds more general. The first one sounds more official and specific, especially in administrative or customer-service contexts.

Yes, chci can be tricky for English speakers.

A rough guide:

• ch in Czech is like the ch in Scottish loch or German Bach
• c is pronounced like ts
• so chci sounds roughly like kh-tsee, said quickly together

The cluster chc- is awkward at first, but it is normal in Czech. Try saying it slowly first:

• ch...ci
• then faster: chci

You do not need to insert a vowel between the sounds.

A rough pronunciation guide is:

vy-OOCH-toh-vah-nee

A few details:

• vy = roughly vih or vee with a short Czech y/i-type sound
• ú = a long oo
• č = ch in church
• á = a long a
• ní at the end = nee

The stress in Czech is usually on the first syllable, so:

VY-účtování

Even though some later vowels are long, the main stress still stays at the beginning.

Yes, a little.

Reklamovat is normally treated as an imperfective verb. In this sentence, that is completely normal, because after chci Czech often uses an infinitive simply to describe the intended action:

• Chci reklamovat vyúčtování.
  = I want to dispute the billing.

The sentence focuses on the intention to perform the action, not on whether it will be completed successfully.

For everyday use, learners do not usually need to worry much more about aspect with this exact sentence.

No, that would not work as a normal sentence.

Reklamace is a noun meaning complaint/claim, while reklamovat is the verb.

So if you want a full sentence with I want to..., you need the verb:

• Chci reklamovat vyúčtování.

You could use the noun in a different structure, for example:

• Chci podat reklamaci vyúčtování.
  = I want to file a complaint about the billing.

But that is a different construction.

Yes, but often with a more polite or more specific phrasing.

Natural possibilities include:

• Chtěl bych reklamovat vyúčtování.
• Chci reklamovat toto vyúčtování.
• Chci podat reklamaci k tomuto vyúčtování.
• Mám výhrady k vyúčtování a chci ho reklamovat.

So your sentence is correct and understandable, but in real service situations speakers often make it a little softer or more specific.
