Internetové bankovnictví funguje.

Funguje means works, functions, or is working.

In this sentence, Internetové bankovnictví funguje. means that the internet banking system is functioning properly.

The verb is fungovat = to function / to work.

• funguji = I work / function
• funguješ = you work / function
• funguje = it works / he works / she works

Here it is funguje because the subject, internetové bankovnictví, is grammatically singular.

Because internetové has to agree with bankovnictví.

In Czech, adjectives change their endings to match the noun’s:

• gender
• number
• case

Bankovnictví is:

• neuter
• singular
• nominative here

So the adjective must also be neuter singular nominative, which gives:

• masculine: internetový
• feminine: internetová
• neuter: internetové

So:

• internetový obchod = internet shop
• internetová stránka = internet page / website
• internetové bankovnictví = internet banking

Bankovnictví is a neuter noun meaning banking.

It is an abstract noun, similar to English words like banking, engineering, or administration.

The ending -í is very common in Czech neuter abstract nouns, and -ství / -nictví is also a common noun-forming pattern.

So bankovnictví refers to the field or system of banking, not to a single bank.

Pretty much, yes.

• internetové = internet / online
• bankovnictví = banking

So internetové bankovnictví is the standard Czech way to say internet banking or online banking.

Depending on context, people may also talk about:

• online bankovnictví
• elektronické bankovnictví

But internetové bankovnictví is a very normal and natural phrase.

Because the whole subject, internetové bankovnictví, is one singular thing.

Even though the phrase has two words, the head noun is bankovnictví, and that noun is singular. So the verb must also be singular:

• Internetové bankovnictví funguje. = Internet banking works.

If the subject were plural, the verb would be plural too:

• Služby fungují. = The services work.

It is in the nominative case, because it is the subject of the sentence.

The basic structure is:

• subject: Internetové bankovnictví
• verb: funguje

So the sentence literally works like:

• Internet banking
  • works

That means the noun phrase is in nominative.

It is present tense, but like the English present tense, it can express either:

1. what is happening now
   
   • The internet banking is working right now

or

2. a general fact
   
   • Internet banking works / functions

Without more context, Czech allows both readings, just like English often does.

A rough pronunciation guide is:

IN-ter-ne-to-vé BAN-kov-nict-ví FUN-gu-ye

A few useful points:

• Czech stress is usually on the first syllable of each word.
• é and í are long vowels.
• j in Czech sounds like English y in yes.

So funguje sounds roughly like FUN-gu-ye, not like English fun-gooj or fun-gway.

Yes, Czech word order is flexible, but Internetové bankovnictví funguje. is the most neutral and natural order.

This standard order is:

• subject + verb

You might change the order for emphasis, but that would sound less neutral. For example, putting funguje first could emphasize that it works, perhaps in contrast to something else.

For a learner, the safest default is:

• Internetové bankovnictví funguje.

Often yes, but it is closer to to function in its most basic sense.

So fungovat is used for things like:

• machines
• systems
• plans
• methods
• services

Examples:

• Počítač funguje. = The computer works.
• To nefunguje. = That doesn’t work.
• Systém funguje dobře. = The system works well.

So in this sentence, funguje means the banking system is functioning properly.

Yes.

In Czech, ordinary adjectives like internetové are normally lowercase. It is capitalized here only because it starts the sentence:

• Internetové bankovnictví funguje.
• Nevím, jestli internetové bankovnictví funguje.

In the second sentence, internetové is no longer at the beginning, so it stays lowercase.

Yes, in natural English you would usually say:

• Online banking works
• Internet banking works
• The online banking is working

Which English version fits best depends on context. But the Czech sentence itself is simple and general: internet banking is functioning.

Normally no, not in this meaning.

It behaves like an abstract, uncountable noun, similar to English banking. So you usually talk about it as a general system or field, not as separate countable items.

That is why a sentence like Internetové bankovnictví funguje treats it as one general thing.
