Ovo je apsolutno točno.

Ovo is the neuter singular form of this when it stands by itself, without a noun.

In Croatian, this changes depending on gender:

• ovaj = masculine
• ova = feminine
• ovo = neuter

When you are pointing to a whole statement, idea, situation, or something unspecified, Croatian often uses ovo:

• Ovo je važno.
• Ovo je istina.
• Ovo je apsolutno točno.

So here ovo does not refer to a specific masculine or feminine noun. It means something like this (thing / statement / idea).

If there were a noun, the form would match that noun:

• Ovaj odgovor je točan. = This answer is correct.
• Ova rečenica je točna. = This sentence is correct.
• Ovo objašnjenje je točno. = This explanation is correct.

Je is the 3rd person singular present form of the verb biti (to be).

So:

• ovo = this
• je = is
• apsolutno točno = absolutely correct / absolutely true

Croatian often uses forms of biti just like English uses to be:

• To je dobro. = That is good.
• Ovo je jasno. = This is clear.
• On je ovdje. = He is here.

In this sentence, je links ovo with the description apsolutno točno.

Because it agrees with ovo, which is neuter singular.

Croatian adjectives usually agree with the noun or pronoun they describe in gender, number, and case.

The adjective točan changes like this in the singular nominative:

• točan = masculine
• točna = feminine
• točno = neuter

So:

• Ovaj odgovor je točan.
• Ova tvrdnja je točna.
• Ovo je točno.

Since ovo is neuter singular, the adjective must also be točno.

Here apsolutno is an adverb.

It modifies točno, not ovo.

So the structure is basically:

• Ovo je
  • točno
• apsolutno strengthens točno

In other words, apsolutno means absolutely, and it tells you how true/correct something is.

Compare:

• To je točno. = That is correct.
• To je apsolutno točno. = That is absolutely correct.

So apsolutno is not agreeing in gender with anything here; it stays the same because it is an adverb.

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

The neutral, standard order here is:

• Ovo je apsolutno točno.

You may also hear:

• Ovo je točno.
• To je apsolutno točno.
• Apsolutno je točno.
  This shifts the focus slightly toward absolutely.

Croatian often changes word order for emphasis, rhythm, or style. But for a learner, the safest default is the original order:

• subject/pronoun + je + adverb + adjective

So Ovo je apsolutno točno is a very natural sentence to remember.

Both can be translated as this/that, but the difference is about distance or mental focus.

• ovo = this, something close to the speaker
• to = that, something a bit more removed, or something already mentioned

So:

• Ovo je apsolutno točno. = This is absolutely correct.
• To je apsolutno točno. = That is absolutely correct.

In real conversation, to is often very common when responding to something someone said:

• To je točno.

Ovo can feel more like you are pointing to something near you, or to the statement you are currently presenting.

It can mean either, depending on context.

Common senses of točno include:

• correct
• true
• accurate
• exact

Examples:

• To je točno. = That is true / correct.
• Točan odgovor. = Correct answer.
• Točno vrijeme. = Exact time / accurate time.

So in Ovo je apsolutno točno, the exact English wording depends on context:

• This is absolutely correct.
• This is absolutely true.

Both are possible.

Yes, they are basically the same word, but točno is the standard Croatian form, while tačno is used in some other varieties of the language area, especially Serbian and Bosnian.

For standard Croatian, you should learn and use:

• točno

So a Croatian learner sentence would normally be:

• Ovo je apsolutno točno.

not

• Ovo je apsolutno tačno.

A simple approximate pronunciation is:

• ovo ≈ OH-vo
• je ≈ yeh
• apsolutno ≈ ap-so-LOOT-no
• točno ≈ TOCH-no

A few useful points:

• j in Croatian is pronounced like English y in yes
• č sounds like ch in church, but typically a bit firmer/cleaner
• Croatian spelling is quite phonetic, so words are usually pronounced much as they are written

So točno is not tok-no or toh-no; the č is important.

In standard Croatian, in the present tense, you normally keep je in a sentence like this.

So:

• Ovo je točno. ✅
• Ovo točno. ❌

Croatian does sometimes omit parts of biti in very informal speech, headlines, notes, or special structures, but as a learner you should treat je as necessary here.

It is mostly neutral standard Croatian. It works well in conversation, writing, explanation, or discussion.

• apsolutno adds strong emphasis, so it can sound a bit forceful: absolutely
• točno is standard and natural
• the whole sentence sounds clear and idiomatic

Some related alternatives are:

• Ovo je točno. = less emphatic
• To je potpuno točno. = completely correct / true
• To je sasvim točno. = quite / entirely correct
• To je istina. = that is true

So Ovo je apsolutno točno is perfectly natural when you want to strongly confirm something.

Croatian does not have articles like English a/an/the.

So where English says:

• This is the truth
• This is a correct answer
• That is the explanation

Croatian simply uses the noun, adjective, or pronoun without an article:

• Ovo je istina.
• Ovo je točan odgovor.
• To je objašnjenje.

In Ovo je apsolutno točno, there is no missing word. The sentence is complete exactly as it is.
