Provjerite broj leta.

Provjerite means check or verify.

In this sentence, it is a command or instruction. Depending on context, it can sound like:

• Check the flight number.
• Verify the flight number.

Both are good translations.

The ending -ite marks the imperative for:

• you all plural
• you formal singular

So Provjerite can mean:

• Check! when speaking to several people
• Please check. when speaking politely to one person

This is very common in signs, announcements, instructions, and customer-service language.

The infinitive is provjeriti.

So the forms are:

• provjeriti = to check, to verify
• provjeri! = check! informal singular
• provjerite! = check! formal singular or plural

Because Croatian often expresses X of Y by putting the second noun in the genitive case.

So:

• broj = number
• let = flight
• leta = of the flight

That means:

• broj leta = flight number
• literally: number of the flight

This is a very common pattern in Croatian.

Broj is in the accusative singular, because it is the direct object of Provjerite.

However, for many masculine inanimate nouns, the accusative singular looks the same as the nominative singular.

So:

• nominative: broj
• accusative: broj

They look identical, but the function in the sentence is different.

Leta is genitive singular of let.

Here it is used after broj to mean:

• the number of the flight
• more naturally in English: the flight number

So the structure is:

• broj
  • genitive
• broj leta

It is formal if spoken to one person, and it can also be plural if spoken to several people.

So this form is very suitable for:

• airport signs
• announcements
• written instructions
• polite service situations

If you were speaking to one friend, you would usually say:

• Provjeri broj leta.

Because Croatian does not have articles like English a or the.

So broj leta can mean:

• a flight number
• the flight number

The exact meaning depends on context.

In this sentence, English naturally uses the:

• Check the flight number.

Provjeriti is perfective.

That means it usually refers to checking something as a completed action: do the check, confirm it.

Its imperfective partner is usually provjeravati.

Very roughly:

• provjeriti = to check/verify once, successfully, as a complete act
• provjeravati = to be checking, to check repeatedly, to check from time to time

In an instruction like this, the perfective provjerite is very natural, because it tells someone to perform the action and complete it.

Yes, Croatian word order is more flexible than English.

The normal neutral order here is:

• Provjerite broj leta.

You might also hear other orders in special contexts, but this one is the most straightforward and standard for an instruction.

For a learner, this is the best version to remember.

You would say:

• Provjeri broj leta.

Compare:

• Provjeri = informal singular
• Provjerite = formal singular or plural

So if you are talking to a friend, sibling, or child, Provjeri broj leta. is the usual choice.

A simple English-friendly approximation is:

• pro-VYE-ri-te broy LE-ta

A few notes:

• j in Croatian sounds like English y
• broj sounds roughly like broy
• r is trilled or tapped more than in English
• stress can vary by dialect and teaching style, but this approximation will help you be understood

Yes, it sounds natural and appropriate, especially in written instructions or announcements.

You may also see slightly expanded versions such as:

• Molimo, provjerite broj leta. = Please check the flight number.
• Provjerite broj svojega leta. = Check your flight number.

But Provjerite broj leta. by itself is perfectly normal and clear.
