Ovlašteni servis provjerava potrošnju vode.

Ovlašteni means authorized, licensed, or officially approved.

It ends in -i because it is an adjective agreeing with servis, which is:

• masculine
• singular
• nominative (the subject form)

So:

• ovlašteni servis = authorized service center

This is the indefinite masculine singular adjective form, which is very common in everyday Croatian.

Here servis does not mean service in the abstract English sense. It usually means:

• a service center
• a repair shop
• a maintenance provider

So ovlašteni servis is best understood as:

• authorized service center
• authorized repair service

In contexts involving appliances, meters, or machines, this is a very common meaning.

Provjerava is the:

• 3rd person singular
• present tense of the verb provjeravati / provjeriti (to check, to verify)

It means:

• he/she/it checks
• or more naturally here, checks

Because the subject is ovlašteni servis (the authorized service center), Croatian uses 3rd person singular:

• Ovlašteni servis provjerava...
• The authorized service center checks...

Because it is the direct object of the verb provjerava.

The basic form is:

• potrošnja = consumption

But after a transitive verb like provjeravati (to check), the direct object usually goes into the accusative case.

For a feminine noun ending in -a, the accusative singular usually changes:

• potrošnja → potrošnju

So:

• provjerava potrošnju = checks the consumption

Because vode is in the genitive case.

The phrase potrošnja vode literally means:

• consumption of water

In Croatian, nouns often use the genitive after another noun to express of.

So:

• voda = water (basic dictionary form, nominative)
• vode = of water (genitive singular)

This structure is very common:

• čaša vode = a glass of water
• cijena goriva = the price of fuel
• potrošnja vode = water consumption

Yes, it is a very normal and common expression meaning:

• water consumption
• use of water

It follows a standard Croatian noun + genitive pattern:

• potrošnja struje = electricity consumption
• potrošnja plina = gas consumption
• potrošnja goriva = fuel consumption

So if you learn potrošnja + genitive, you can build many useful phrases.

Because Croatian has no articles like English a/an/the.

So:

• ovlašteni servis can mean an authorized service center or the authorized service center
• potrošnju vode can mean water consumption or the water consumption, depending on context

Croatian usually leaves definiteness to be understood from the situation, context, or word order.

Yes. Croatian word order is more flexible than English because case endings show grammatical roles.

The neutral order here is:

• Ovlašteni servis provjerava potrošnju vode.

But other orders are possible, for example:

• Potrošnju vode provjerava ovlašteni servis.
• Provjerava potrošnju vode ovlašteni servis.

These alternatives may sound more marked or emphasize different parts of the sentence.

Still, for learners, the safest default is:

• subject + verb + object

You know mainly from:

1. word order
2. verb agreement
3. case form

In the basic sentence:

• Ovlašteni servis is in the nominative and functions as the subject.
• provjerava is singular, matching servis.
• potrošnju vode is the object phrase.

So the structure is:

• Ovlašteni servis = subject
• provjerava = verb
• potrošnju vode = object

Yes. Provjerava is grammatically present tense.

Croatian present tense can correspond to several English possibilities depending on context:

• checks
• is checking
• sometimes even something like will check in practical or scheduled contexts

Without broader context, the plain meaning is simply:

• checks

The dictionary forms are:

• ovlašten = authorized
• servis = service center / repair service
• provjeravati or provjeriti = to check / verify
• potrošnja = consumption
• voda = water

In the sentence, some of these appear in changed forms because of grammar:

• ovlašten → ovlašteni
• potrošnja → potrošnju
• voda → vode

Yes, Croatian verb aspect matters.

Here, provjerava comes from the imperfective verb provjeravati.

Croatian often has a pair:

• provjeravati = imperfective, focusing on process, repetition, or general action
• provjeriti = perfective, focusing on a completed check

In a simple present-tense statement like this, the imperfective is normal:

• Ovlašteni servis provjerava potrošnju vode.

If you wanted a completed future action, Croatian would often use the perfective:

• Ovlašteni servis će provjeriti potrošnju vode.
• The authorized service center will check the water consumption.

A rough pronunciation guide:

• š sounds like sh in ship
• nj sounds like the ny sound in canyon or Spanish ñ

So potrošnju is approximately:

• po-TROSH-nyoo

And the whole sentence is roughly:

• ov-LA-shte-nee SER-vees pro-VYE-ra-va po-TROSH-nyoo VO-de

This is only approximate, but it helps with the key sounds.

Sometimes, but authorized service center is usually better.

Official service in English can sound vague or unnatural in many contexts. Croatian ovlašteni servis usually means a business that has official authorization from the manufacturer or provider.

So the most natural translations are:

• authorized service center
• authorized repair service
• licensed service provider (depending on context)

Here is the full breakdown:

• Ovlašteni servis

  • nominative singular
  • subject of the sentence

• potrošnju

  • accusative singular
  • direct object of provjerava

• vode

  • genitive singular
  • depends on potrošnja, meaning of water

So the sentence shows a very typical Croatian pattern:

• subject (nominative) + verb + object (accusative) + genitive complement
