Ravnateljica kaže da će se u zbornici razgovarati o raspustu, a u kabinetu o svjedodžbi.

Ravnateljica is the feminine form of ravnatelj and means female principal / headmistress / director, depending on context.

In this sentence, it tells you that the person speaking is a woman. It is in the nominative singular because it is the subject of kaže.

• ravnatelj = a male principal/director
• ravnateljica = a female principal/director

This is a very common Croatian structure.

• kaže = says
• da = that
• će = future auxiliary, roughly will

So kaže da će... means says that ... will ...

The clause after da is a subordinate clause:

• Ravnateljica kaže = The principal says
• da će se razgovarati... = that there will be discussion / that people will talk...

English sometimes leaves out that, but Croatian normally uses da here.

Here se makes the sentence impersonal.

Razgovarati normally means to talk / to have a conversation. In this sentence, Croatian does not name who will be doing the talking. Instead, it uses an impersonal construction:

• razgovarat će se
• će se razgovarati

Both mean something like:

• people will talk
• there will be discussion
• it will be discussed

So se here does not mean oneself. It helps create an impersonal meaning, similar to English people will... or a passive-like expression.

Because Croatian very often prefers an impersonal construction when the doer is unimportant, obvious, or deliberately left unstated.

So instead of saying:

• Teachers will discuss...
• The staff will talk about...

Croatian can simply say:

• razgovarat će se o... = there will be discussion about...

This is very natural and common in formal or institutional language.

Because u means in here, showing location, and after u in the meaning in/at a place, Croatian uses the locative case.

So:

• zbornica → u zbornici
• kabinet → u kabinetu

Compare:

• u zbornici = in the staff room
• u kabinetu = in the office / classroom / кабинет-type room

Important contrast:

• u zbornici = in the staff room (location, locative)
• u zbornicu = into the staff room (movement, accusative)

Because the preposition o meaning about takes the locative case.

So the base forms change like this:

• raspust → o raspustu
• svjedodžba → o svjedodžbi

This is a very useful rule:

• o + locative = about

Examples:

• o školi = about school
• o profesoru = about the teacher/professor
• o raspustu = about the school break/holiday

Because Croatian often leaves out repeated words when they are easy to understand from context.

The full version would be:

• Ravnateljica kaže da će se u zbornici razgovarati o raspustu, a u kabinetu će se razgovarati o svjedodžbi.

But that sounds repetitive, so Croatian shortens it to:

• ...a u kabinetu o svjedodžbi.

English does this too:

• They will talk about the holiday in the staff room, and in the office about the report card.

The missing part is understood from the first clause.

Here a is best understood as and, but with a slight sense of contrast or switching to another setting/topic.

It often connects two parallel pieces of information:

• u zbornici o raspustu
• a u kabinetu o svjedodžbi

So it is not a strong but, but it is not exactly the plain additive i either. It is more like:

• and meanwhile
• and in the other place
• whereas in the office...

Croatian a often links two related but contrasting parts.

Croatian word order is more flexible than English word order.

This sentence puts the place phrases early:

• u zbornici
• u kabinetu

That helps highlight where each discussion will happen.

A more expanded version could be:

• Ravnateljica kaže da će se razgovarati o raspustu u zbornici, a o svjedodžbi u kabinetu.

That is possible, but the original version sounds neat and well balanced. Croatian often arranges information for emphasis and rhythm, not only according to fixed word order rules.

These words can be slightly context-dependent:

• zbornica = staff room / teachers’ room
• kabinet = often office, but in schools it can also mean a subject classroom, study, or a specialized room
• raspust = school break / holiday / vacation
• svjedodžba = usually school report card or certificate

So the sentence sounds very school-related and fairly formal.

Yes. Both are correct future forms.

You may see:

• će se razgovarati
• razgovarat će se

In this sentence, da će se razgovarati is especially natural after da.

So:

• Ravnateljica kaže da će se razgovarati... = correct
• Ravnateljica kaže da razgovarat će se... = not natural/standard in this structure

After da, the version with će before the infinitive is the normal one.
