Profesorica će sutra najaviti datum ispita.

Profesorica means female professor/teacher, while profesor is masculine.

So this sentence tells you that the person announcing the exam date is a woman.

• profesorica = female professor
• profesor = male professor

Croatian often marks the gender of professions more clearly than English does.

Će is the auxiliary used to form the future tense in Croatian.

In this sentence:

• Profesorica će najaviti = The professor will announce

So će works a bit like English will.

That is one standard way to form the Croatian future tense.

Here:

• će = future auxiliary
• najaviti = infinitive, to announce

Together:

• će najaviti = will announce

With full noun subjects, this structure is very common:

• Profesorica će doći. = The professor will come.
• Studenti će učiti. = The students will study.

Both patterns exist in Croatian, but they are used in different situations.

With a full noun subject like Profesorica, the usual order is:

• Profesorica će najaviti...

The form where the auxiliary attaches after the verb is more typical when there is no explicit noun subject, or in certain standard written patterns:

• Najavit će datum ispita. = She will announce the exam date.

So in your sentence, Profesorica će najaviti... is the natural choice.

Sutra means tomorrow.

It tells you when the action will happen:

• Profesorica će sutra najaviti datum ispita.
• The professor will announce the exam date tomorrow.

Its position is flexible. You could also say:

• Sutra će profesorica najaviti datum ispita.
• Profesorica će najaviti datum ispita sutra.

All of these are grammatical, but the emphasis changes slightly depending on word order.

Croatian word order is generally more flexible than English word order.

English usually depends heavily on fixed order:

• The professor will announce the exam date tomorrow.

Croatian uses cases and verb forms, so the roles of words are clearer even if the order changes.

Your sentence is a very natural neutral order:

• Profesorica = subject
• će najaviti = will announce
• sutra = tomorrow
• datum ispita = exam date

But Croatian allows movement for emphasis.

Here profesorica is in the nominative singular, because it is the subject of the sentence.

You can ask:

• Who will announce the exam date?
• Profesorica.

That tells you it is the subject, so nominative is expected.

Datum is in the accusative singular, because it is the direct object of najaviti.

You can ask:

• What will the professor announce?
• Datum ispita.

For this noun, the nominative and accusative forms look the same:

• nominative: datum
• accusative: datum

So even though the form does not change visibly, its function here is accusative.

Because ispita is genitive singular and means of the exam.

So:

• datum ispita = the date of the exam / the exam date

This is a very common Croatian pattern: one noun followed by another noun in the genitive to show possession or relation.

Examples:

• vrata učionice = the classroom door
• rezultat testa = the test result
• datum ispita = the exam date

Yes. Literally it is:

• datum = date
• ispita = of the exam

So word-for-word it is date of the exam.

In natural English, that is usually expressed as:

• the exam date

This kind of noun + genitive structure is very common in Croatian.

Croatian does not have articles like English a and the.

So datum ispita can mean:

• an exam date
• the exam date

The exact meaning depends on context.

In this sentence, English will usually translate it as the exam date, because that sounds most natural.

Najaviti is a verb meaning to announce.

More specifically, it is a perfective verb. That means it presents the action as a completed whole: making the announcement.

In this sentence, that fits well:

• the professor will make the announcement tomorrow

A related imperfective verb is najavljivati, which would suggest repeated, ongoing, or habitual announcing in the right context.

So:

• najaviti = to announce, to make the announcement
• najavljivati = to be announcing / to announce repeatedly

Će is pronounced roughly like chye or a softer cheh, depending on accent, but the important point is that ć is a soft sound.

A few useful notes:

• č and ć are different letters in Croatian
• ć is softer than č
• će is usually a short unstressed word

If you are just starting, it is better to aim for a soft ch sound than to worry too much about perfect precision immediately.

Yes, in many contexts that is a good English translation.

Croatian future tense with će often corresponds to English:

• will
• is going to

So:

• Profesorica će sutra najaviti datum ispita. can be understood as
• The professor will announce the exam date tomorrow. or
• The professor is going to announce the exam date tomorrow.

Which English version sounds best depends on context and style.

Yes. That position works well for many adverbs of time.

For example:

• Profesorica će danas najaviti datum ispita. = The professor will announce the exam date today.
• Profesorica će uskoro najaviti datum ispita. = The professor will announce the exam date soon.
• Profesorica će kasnije najaviti datum ispita. = The professor will announce the exam date later.

So sutra is just the time expression used in this sentence.
