Večeras ćemo pozvati komšiju u svoj stan.

Večeras means tonight / this evening and it is an adverb of time. Serbian very often puts time expressions near the beginning of the sentence, especially when setting the scene.

So Večeras ćemo pozvati komšiju u svoj stan sounds very natural: first you say when, then the rest.

You could move it later, but that would sound different in focus:

• Večeras ćemo pozvati komšiju u svoj stan. = neutral, natural
• Pozvaćemo komšiju u svoj stan večeras. = also possible, with večeras more like added information at the end

This is the future tense.

Serbian often forms the future with:

• a form of hteti (ću, ćeš, će, ćemo, ćete, će)
• plus the infinitive

Here:

• ćemo = we will
• pozvati = to invite / to call

So:

• ćemo pozvati = we will invite / we will call

Because the subject is understood from ćemo, Serbian does not need a separate word for we.

Because ćemo is a clitic. In Serbian, clitics usually go in the second position of the sentence or clause.

So:

• Večeras = first element
• ćemo = second-position clitic

That is why Večeras ćemo... is the normal order.

This second-position behavior is very common in Serbian, and learners notice it a lot with forms like sam, si, je, smo, ste, su, ću, ćeš, će, ćemo.

Yes. That is also correct.

Serbian has two common ways to express this future:

• Večeras ćemo pozvati komšiju u svoj stan
• Večeras pozvaćemo... is generally not the normal standard order
• Pozvaćemo komšiju u svoj stan večeras = perfectly fine if the verb comes first

When the infinitive comes before the future clitic, Serbian often uses the joined form:

• pozvati + ćemo → pozvaćemo

So Pozvaćemo is a very common form.

This is mainly about aspect.

• zvati = imperfective
• pozvati = perfective

In this sentence, the speaker is talking about one complete future action: inviting the neighbor over. Serbian usually prefers the perfective verb for that kind of meaning.

So:

• pozvati = to invite / call once, as a completed act
• zvati would suggest something more ongoing, repeated, or less bounded, depending on context

Also, in this sentence pozvati ... u svoj stan clearly means invite someone over, not just call in a general sense.

Yes. Depending on context, pozvati can mean:

• to call
• to invite

Here, the phrase u svoj stan makes the meaning clearly invite into one’s apartment.

Without that phrase, Pozvaćemo komšiju could sometimes be understood as We’ll call the neighbor, depending on the situation.

Because komšiju is the accusative singular, and here komšiju is the direct object of the verb pozvati.

Dictionary form:

• komšija = neighbor

But after a transitive verb like pozvati, you need the accusative:

• pozvati koga? → komšiju

This is especially important because komšija refers to a male animate person. Masculine animate nouns change in the accusative.

So:

• nominative: komšija
• accusative: komšiju

Because svoj is the reflexive possessive pronoun, and Serbian usually uses it when the possessor is the same as the subject.

Here, the subject is we:

• ćemo pozvati = we will invite

And whose apartment is it?

• our own apartment, belonging to the subject

So Serbian naturally uses:

• svoj stan = our own apartment in this sentence

Using naš stan is possible in some contexts, but svoj is the more natural choice when the owner is the same as the subject.

A rough rule:

• use svoj for one’s own
• use moj, tvoj, naš, vaš, njegov... when you are not using that reflexive relationship, or when you want contrast/emphasis

Because u can take different cases depending on the meaning.

Here it expresses movement toward / into a place, so it takes the accusative:

• u svoj stan = into/to one’s apartment

If it meant location inside the apartment, it would take the locative:

• u svom stanu = in one’s apartment

Compare:

• Pozvaćemo komšiju u svoj stan. = We will invite the neighbor into our apartment.
• Večeras ćemo biti u svom stanu. = Tonight we will be in our apartment.

Because stan is a masculine inanimate noun, and for many such nouns the accusative singular looks the same as the nominative singular.

So:

• nominative: stan
• accusative: stan

The adjective shows the case more clearly:

• svoj stan = accusative masculine singular

So even though stan itself does not visibly change, the phrase is still in the accusative.

Stan means apartment or flat.

It usually refers to a private living space in a building. In English, apartment is often the easiest translation.

So:

• u svoj stan = to/into our apartment

It is not written as a separate word, but it is understood from ćemo.

Serbian often leaves out subject pronouns when the verb form already shows the person and number clearly.

Here:

• ćemo = we will

So there is no need to add mi unless you want emphasis:

• Mi ćemo pozvati komšiju... = We will invite the neighbor...

That version sounds more contrastive or emphatic.

Yes. Serbian word order is fairly flexible, but the meaning and emphasis can shift.

For example:

• Večeras ćemo pozvati komšiju u svoj stan. = neutral, natural
• Komšiju ćemo večeras pozvati u svoj stan. = extra focus on the neighbor
• U svoj stan ćemo večeras pozvati komšiju. = extra focus on into our apartment
• Pozvaćemo komšiju u svoj stan večeras. = also natural

What stays important is:

• ćemo tends to behave like a second-position clitic
• case endings show grammatical roles, so the words can move more freely than in English
