Na poslu koristimo stvari kao što su stalci za prijenosna računala.

Na poslu is a very common Croatian expression meaning at work or at the workplace.

• posao = work / job
• after na in the sense of location, Croatian normally uses the locative case
• the locative singular of posao is poslu

So:

• posao = work, job
• na poslu = at work

This is one of those expressions you will see very often, just like:

• na fakultetu = at university
• na stolu = on the table
• na sastanku = at the meeting

So the ending changes because the noun is in the locative, not because the meaning of posao itself changes.

Koristimo means we use.

It comes from the verb koristiti = to use.

This is the 1st person plural present tense form:

• ja koristim = I use
• ti koristiš = you use
• on/ona koristi = he/she uses
• mi koristimo = we use
• vi koristite = you use
• oni koriste = they use

So in the sentence:

• Na poslu koristimo... = At work, we use...

Also, koristiti is normally an imperfective verb, so it fits general or habitual use well, like we use these things at work.

Here stvari means things.

The basic noun is:

• stvar = thing

In the sentence, stvari is the plural direct object of koristimo, so it is in the accusative plural.

For this noun, the nominative plural and accusative plural look the same:

• stvari = things

So although the form does not change visibly, its function is accusative because it is the thing being used:

• koristimo stvari = we use things

This is very common in Croatian: sometimes a case is determined by function, even if the spelling looks identical to another case.

In this sentence, kao što su means such as.

So:

• stvari kao što su stalci... = things such as stands...

Literally, kao što su is something like as what are, but you should learn it as a fixed expression meaning:

• such as
• like
• for example

A very useful pattern is:

• kao što je
  • singular noun
• kao što su
  • plural noun

Examples:

• gradovi kao što su Split i Zadar = cities such as Split and Zadar
• uređaj kao što je printer = a device such as a printer

In your sentence, stalci is plural, so Croatian uses su.

Because the noun that follows is plural:

• stalci = stands

So Croatian uses the plural form of to be:

• je = is
• su = are

Compare:

• stvar kao što je stalak = a thing such as a stand
• stvari kao što su stalci = things such as stands

So su agrees with the plural noun being introduced.

Stalci means stands.

The singular is:

• stalak = stand

Plural:

• stalci = stands

This is a masculine noun. The plural changes a bit:

• stalak → stalci

That kind of change is normal in Croatian and has to be learned with the noun.

In this sentence, stalci is in the nominative plural, because it comes after su in the phrase kao što su stalci...

The phrase za prijenosna računala means for laptops.

Breakdown:

• za = for
• prijenosna računala = laptops

In Croatian, za often takes the accusative case.

The singular noun is:

• prijenosno računalo = laptop, portable computer

Plural:

• prijenosna računala = laptops

So after za, you get:

• za prijenosno računalo = for a laptop
• za prijenosna računala = for laptops

The adjective prijenosna agrees with računala in gender, number, and case.

Yes, literally računalo means computer.

But prijenosno računalo literally means portable computer, which is the standard Croatian way to say laptop.

So:

• računalo = computer
• prijenosno računalo = laptop

In everyday speech, many Croatians also say laptop, but prijenosno računalo is a fully normal and standard Croatian expression.

It is in the accusative plural, because it follows za in the sense for.

Base form:

• prijenosno računalo = nominative singular

After za:

• za prijenosno računalo = accusative singular

Plural:

• prijenosna računala = nominative plural
• za prijenosna računala = accusative plural

For neuter plural nouns like računala, the nominative and accusative plural are often the same in form, so the spelling does not change, even though the grammatical case is accusative.

Because the noun is plural.

Singular:

• prijenosno računalo = a laptop

Plural:

• prijenosna računala = laptops

The adjective has to agree with the noun:

• računalo is neuter singular → prijenosno
• računala is neuter plural → prijenosna

This agreement is an important feature of Croatian grammar.

Yes. If you only want to say We use laptop stands at work, you could simply say:

• Na poslu koristimo stalke za prijenosna računala.

That is more direct.

But the original sentence means something slightly broader:

• Na poslu koristimo stvari kao što su stalci za prijenosna računala.
• At work we use things such as laptop stands.

So stvari kao što su... introduces examples rather than giving a complete list.

Good question. This is about case.

After koristimo, the direct object is in the accusative:

• Koristimo stalke. = We use stands.

But in the original sentence, stalci comes after su:

• ...kao što su stalci...

Here stalci is not the direct object of koristimo. Instead, it is part of the phrase such as stands, where Croatian uses su and a nominative noun.

So:

• stalci = nominative plural
• stalke = accusative plural

Compare:

• Stalci su korisni. = Stands are useful.
• Koristimo stalke. = We use stands.

Yes, Croatian word order is fairly flexible, although some versions sound more natural than others.

The given sentence is perfectly natural:

• Na poslu koristimo stvari kao što su stalci za prijenosna računala.

You could also hear variations such as:

• Koristimo na poslu stvari kao što su stalci za prijenosna računala.
• Na poslu koristimo, primjerice, stalke za prijenosna računala.

But the original order is clear and natural because it starts with the context na poslu and then gives the main action koristimo.

Yes. Besides kao što su, Croatian can also use expressions like:

• poput = like / such as
• na primjer = for example
• primjerice = for example

For example:

• Na poslu koristimo stvari poput stalaka za prijenosna računala.
• Na poslu koristimo stvari, na primjer stalke za prijenosna računala.

These are all possible, but they are not identical in structure.

Notice that after poput, the following noun changes form:

• poput stalaka = like/such as stands

So for learners, kao što su is often easier at first because the noun stays in the nominative:

• kao što su stalci

A singular version would be:

• Na poslu koristimo stvar kao što je stalak za prijenosno računalo.

Changes:

• stvari → stvar
• su → je
• stalci → stalak
• prijenosna računala → prijenosno računalo

So the pattern is:

• plural: stvari kao što su stalci
• singular: stvar kao što je stalak

This is a very useful comparison for understanding agreement in Croatian.

The structure is:

• Na poslu = at work
• koristimo = we use
• stvari = things
• kao što su stalci za prijenosna računala = such as laptop stands

So literally:

• At work we use things such as stands for portable computers.

Natural English:

• At work we use things such as laptop stands.

This sentence is useful because it combines several common Croatian patterns:

• a prepositional location phrase: na poslu
• a present-tense verb: koristimo
• a direct object: stvari
• the expression kao što su = such as
• a purpose phrase with za: za prijenosna računala
