Vi ćete posle večere razgovarati sa majkom.

Vi means you in the plural, but it is also used as the formal singular form, like you in polite English but marked more clearly.

When it is capitalized as Vi, that often shows extra politeness in writing when speaking to one person formally. In ordinary sentences, you may also see lowercase vi.

So in this sentence, Vi most likely means:

• you (speaking politely to one person), or
• you all / you plural, depending on context

The capitalization strongly suggests the formal singular reading.

This is the future I tense in Serbian.

It is formed with:

• the present tense of hteti (to want, but used as a future auxiliary)
• plus the infinitive of the main verb

Here:

• ćete = future auxiliary for you (plural/formal)
• razgovarati = to talk / to have a conversation

So:

• ja ću razgovarati = I will talk
• ti ćeš razgovarati = you will talk
• Vi ćete razgovarati = you will talk

This is very similar to English will + verb.

Because after the future auxiliary, Serbian normally uses the infinitive of the main verb.

So the correct structure is:

• ćete razgovarati

not:

• ćete razgovarate

That second version is wrong because razgovarate is a present-tense form, while after ću/ćeš/će/ćemo/ćete/će you normally use the infinitive.

Razgovarati means to talk, to converse, or to have a conversation. It is an imperfective verb, which makes sense here because it describes an ongoing activity rather than a completed action.

It commonly appears with:

• sa + instrumental = with someone
• sometimes o + locative = about something

Examples:

• Razgovaram sa prijateljem. = I am talking with a friend.
• Razgovaramo o poslu. = We are talking about work.

Because the preposition sa (with) requires the instrumental case.

The noun majka changes in the instrumental singular:

• nominative: majka = mother
• instrumental: majkom = with mother / with the mother

So:

• sa majkom = with (your/the) mother

This is one of the most important things to notice in Serbian: prepositions often force nouns into a specific case.

Serbian often leaves possession unstated when it is obvious from context.

So sa majkom can mean:

• with your mother
• with the mother
• sometimes even with his/her mother

depending on the situation.

If Serbian wants to be more explicit, it can say:

• sa vašom majkom = with your mother (formal/plural)
• sa svojom majkom = with one’s own mother

But in many everyday sentences, Serbian simply uses majkom and lets context do the work.

Posle means after, and it requires the genitive case.

The noun večera (dinner / supper) changes like this:

• nominative: večera
• genitive: večere

So:

• posle večere = after dinner

This is a very common pattern:

• posle škole = after school
• posle sastanka = after the meeting
• posle ručka = after lunch

Yes.

• posle is common in Ekavian Serbian
• poslije is the corresponding Ijekavian form

You may also see nakon, which also means after and likewise takes the genitive:

• nakon večere

So these are all possible, depending on region and style:

• posle večere
• poslije večere
• nakon večere

Yes, Serbian word order is fairly flexible.

This sentence is neutral and natural. But other orders are also possible, depending on emphasis:

• Vi ćete posle večere razgovarati sa majkom.
  Neutral: You will talk with mother after dinner.

• Posle večere ćete razgovarati sa majkom.
  Emphasizes after dinner.

• Sa majkom ćete razgovarati posle večere.
  Emphasizes with mother.

The meaning stays basically the same, but the focus shifts.

One important detail: the auxiliary ćete tends to stay in second position in the clause, which is a common Serbian pattern for clitic-like elements.

Yes. Serbian often drops subject pronouns because the verb form already shows the subject.

So you can say:

• Ćete posle večere razgovarati sa majkom.

However, in practice this sounds less natural at the beginning of a sentence by itself than:

• Razgovaraćete sa majkom posle večere.
• Posle večere ćete razgovarati sa majkom.

Including Vi is useful when you want:

• politeness
• contrast
• emphasis
• clarity

So Vi is not always necessary, but it is perfectly fine here.

Yes. Serbian often has two future-tense patterns:

• Vi ćete razgovarati
• Razgovaraćete

Both mean you will talk.

The second form combines the auxiliary with the verb in a single written word. Both are correct, though style, rhythm, and sentence structure may influence which one sounds better.

In your sentence, the split form Vi ćete razgovarati is especially clear for learners because it shows the future auxiliary more transparently.

It can be either, depending on context.

Razgovarati simply means to talk / to have a conversation. It is neutral. It could mean:

• casual chatting
• discussing something important
• having a serious conversation

If the context is serious, Serbian might also use words like:

• porazgovarati = to have a talk
• pričati = to talk, often more casual
• diskutovati = to discuss

But razgovarati sa majkom is a normal, neutral phrase.

There are two especially important case forms here:

• večere = genitive singular after posle
• majkom = instrumental singular after sa

So this sentence is a good example of how Serbian uses cases after prepositions:

• posle + genitive
• sa + instrumental

If you remember just that, you are already getting a lot of useful grammar from this one sentence.
