Provjerite energetsku oznaku i razred energetske učinkovitosti.

Provjerite is the imperative form of provjeriti (to check, to verify).

In this sentence, it is the 2nd person plural imperative, which is used:

• when speaking to more than one person, or
• as a polite/formal singular command, like English Check... in an instruction or notice.

So Provjerite means Check!

Compare:

• provjeri = check! (to one person, informal)
• provjerite = check! (to several people, or one person formally/politely)

This form is very common in instructions, signs, manuals, and advertisements.

Because energetsku oznaku is the direct object of Provjerite, so it must be in the accusative case.

The dictionary forms are:

• energetska = energetic/energy-related
• oznaka = label, mark

Since oznaka is:

• feminine
• singular
• accusative

the adjective must match it:

• nominative: energetska oznaka
• accusative: energetsku oznaku

So after a verb like provjeriti (to check), you get:

• Provjerite energetsku oznaku.

Because razred is also a direct object, and it is a masculine inanimate noun.

In Croatian, for masculine inanimate nouns, the accusative singular is usually the same as the nominative singular.

So:

• nominative: razred
• accusative: razred

That is why the sentence has:

• Provjerite ... razred ...

not razreda.

A useful pattern:

• vidim stol = I see the table
• provjerite razred = check the class/category

Because this part means of energy efficiency and depends on razred.

The structure is:

• razred = class/category
• energetske učinkovitosti = of energy efficiency

So together:

• razred energetske učinkovitosti = energy efficiency class

This is a very common Croatian structure:

• noun + genitive phrase

For example:

• boja auta = the color of the car
• cijena proizvoda = the price of the product
• razred energetske učinkovitosti = the class of energy efficiency

English often uses noun stacking (energy efficiency class), but Croatian often prefers a head noun + genitive structure.

Because energetske učinkovitosti is in the genitive singular.

The base forms are:

• energetska = energy-related
• učinkovitost = efficiency

Here, učinkovitost depends on razred, so it becomes genitive:

• nominative: energetska učinkovitost
• genitive: energetske učinkovitosti

The adjective energetska must agree with učinkovitost, so it changes too:

• nominative feminine singular: energetska
• genitive feminine singular: energetske

So:

• razred energetske učinkovitosti = class of energy efficiency

I simply means and.

It joins two direct objects of Provjerite:

• energetsku oznaku
• razred energetske učinkovitosti

So the structure is:

• Check [the energy label] and [the energy efficiency class].

Croatian often does this very directly, just like English.

Here are the basic dictionary forms:

• provjeriti = to check, to verify
• energetski / energetska / energetsko = energy-related
• oznaka = label, mark, designation
• i = and
• razred = class, category, grade
• učinkovitost = efficiency

Forms actually used in the sentence:

• Provjerite ← from provjeriti
• energetsku ← from energetska
• oznaku ← from oznaka
• razred ← same form as dictionary form here
• energetske ← from energetska
• učinkovitosti ← from učinkovitost

Yes, very often it is.

Energetska oznaka commonly means energy label, especially on appliances or products. It is a standard expression in consumer information and regulations.

Similarly, razred energetske učinkovitosti is also a standard phrase meaning energy efficiency class/rating.

So even though you can analyze the grammar word by word, these are also useful chunks to learn as set phrases:

• energetska oznaka
• razred energetske učinkovitosti

Yes, but the tone changes.

• Provjeri = singular informal command, used with one person you address as ti
• Provjerite = plural command, or polite/formal singular, used with vi

So:

• Provjeri energetsku oznaku... = Check the energy label... (to one friend, child, etc.)
• Provjerite energetsku oznaku... = Check the energy label... (formal/polite, or to multiple people)

In public instructions, labels, and advertisements, Provjerite is much more common.

Because this sentence uses a slightly fuller structure:

• razred energetske učinkovitosti = class of energy efficiency

Croatian can also use:

• energetski razred

depending on context, but razred energetske učinkovitosti is more explicit and precise. It spells out exactly what kind of class is meant.

So the sentence is not saying:

• energy class

but more exactly:

• energy efficiency class

That is why the phrase is built with razred + genitive.

Yes, Croatian word order is fairly flexible, but not every version sounds equally natural.

The given sentence:

• Provjerite energetsku oznaku i razred energetske učinkovitosti.

is natural and standard.

You could rearrange parts for emphasis, but in ordinary instructions this version is the best choice. Croatian often keeps instructional sentences clear and straightforward:

• verb first
• then the objects

So for learners, this is a good default pattern to remember:

• Verb + object(s)

A very useful chunking is:

• Provjerite = Check
• energetsku oznaku = the energy label
• i = and
• razred energetske učinkovitosti = the energy efficiency class

Or grammatically:

• Provjerite = imperative verb
• energetsku oznaku = direct object 1
• i = conjunction
• razred energetske učinkovitosti = direct object 2, where energetske učinkovitosti modifies razred

This helps you see that the sentence is structurally quite simple, even though some forms change because of case.

Probably these two points:

1. Direct objects often go in the accusative

   • energetska oznaka → energetsku oznaku

2. Croatian often uses a genitive phrase where English uses a noun chain

   • razred energetske učinkovitosti
   • literally: class of energy efficiency
   • natural English: energy efficiency class

So this one sentence gives you two very common Croatian patterns:

• imperative + accusative object
• noun + genitive complement
