Proveriću informaciju.

It is future tense, specifically future I in Serbian.

The verb proveriću means I will check / I will verify. It comes from the verb proveriti and the future auxiliary ću.

So, grammatically:

• proveriti = to check / to verify
• ću = I will
• proveriću = I will check

Because in standard Serbian, when the future auxiliary ću comes directly after an infinitive ending in -ti, it attaches to the verb and the -ti drops.

So:

• proveriti + ću → proveriću

This is very common:

• uraditi + ću → uradiću
• videti + ću → videću
• proveriti + ću → proveriću

But if the auxiliary comes before the infinitive, it stays separate:

• Ja ću proveriti informaciju.

Both are correct; they are just built differently.

Because informaciju is in the accusative case.

The verb proveriti takes a direct object, and in Serbian the direct object is often put in the accusative.

Base form:

• informacija = information / a piece of information

Accusative singular:

• informaciju

This is a normal pattern for many feminine nouns ending in -a:

• knjiga → knjigu
• poruka → poruku
• informacija → informaciju

Because Serbian often omits subject pronouns when they are already clear from the verb form.

In proveriću, the ending tells you that the subject is I.

So:

• Proveriću informaciju. = I will check the information.
• Ja ću proveriti informaciju. = also I will check the information

You add ja only when you want emphasis, contrast, or clarity:

• Ja ću proveriti informaciju, ne on.
  I will check the information, not him.

Proveriti is perfective.

That means it refers to a completed action: checking something and reaching the result.

So Proveriću informaciju suggests:

• I will check it
• I will complete that check

Its imperfective partner is usually proveravati.

Compare:

• Proveriću informaciju. = I will check the information.
  completed, one whole action

• Proveravam informaciju. = I am checking the information / I check the information.
  ongoing, repeated, or habitual action

This aspect difference is very important in Serbian.

Yes. That is completely correct and very natural.

These are both fine:

• Proveriću informaciju.
• Ja ću proveriti informaciju.

The difference is mostly style and emphasis:

• Proveriću informaciju. = shorter, neutral, common
• Ja ću proveriti informaciju. = slightly more explicit; can sound more emphatic depending on context

In everyday Serbian, both are used.

Yes. That is also very common in spoken Serbian.

You will hear both patterns:

• Ja ću proveriti informaciju.
• Ja ću da proverim informaciju.

They usually mean the same thing.

Very roughly:

• ću + infinitive can sound a bit more neutral or formal in some contexts
• ću da + present is extremely common in conversation

So if you hear Ja ću da proverim informaciju, do not be surprised. It is normal Serbian.

Yes. Serbian word order is fairly flexible because case endings show grammatical roles.

Possible versions include:

• Proveriću informaciju.
  neutral

• Ja ću proveriti informaciju.
  explicit subject

• Informaciju ću proveriti.
  puts more focus on informaciju

But there is an important rule: ću is a clitic, so it usually cannot stand at the very beginning of the sentence by itself.

So this is not natural by itself:

• Ću proveriti informaciju. ❌

But these are fine:

• Ja ću proveriti informaciju.
• Informaciju ću proveriti.

Serbian has no articles like English a/an/the.

So informaciju does not itself tell you whether it is:

• the information
• some information
• a piece of information

You understand that from context.

If you want to be more specific, Serbian often uses demonstratives:

• tu informaciju = that information
• ovu informaciju = this information

So Proveriću informaciju can be understood in different ways depending on the situation, even though English usually forces you to choose.

That is a very common difference between the two languages.

In Serbian, informacija is a normal countable noun. It often means:

• a piece of information
• a bit of information
• a piece of news

So Serbian can naturally say:

• jedna informacija = one piece of information
• dve informacije = two pieces of information

That is why Proveriću informaciju sounds normal in Serbian. In English, depending on context, the best translation might be either:

• I’ll check the information
• I’ll check that piece of information

A rough pronunciation guide is:

• proveriću ≈ pro-ve-ri-ću
• informaciju ≈ in-for-ma-ci-ju

A few useful sound notes:

• ć is a soft sound, somewhat like a very soft ch.
  It is not exactly the same as English ch, but that is a decent approximation at first.

• c is pronounced ts

• j is pronounced like English y

So:

• ci sounds like tsi
• ju sounds like yu

If you want a rough English-friendly approximation, the whole sentence is something like:

• pro-ve-ri-chu in-for-ma-tsi-yu

Not perfect, but close enough for a beginner.
