Sastavićemo komodu danas.

Sastavićemo is future tense: we will assemble / put together.

It comes from:

• the verb sastaviti = to assemble, to put together
• the future auxiliary ćemo = we will

So the full idea is:

• sastaviti + ćemo → sastavićemo

This is the 1st person plural future form: we will.

In Serbian, future tense can often be formed in two ways with many verbs:

• Sastavićemo komodu danas.
• Ćemo sastaviti komodu danas.

The first version is the contracted form, where the auxiliary attaches to the verb stem:

• sastaviti → drop -ti
• add ćemo
• sastavićemo

This is completely standard.

Grammatically, yes, but in normal Serbian word order you would usually say:

• Sastavićemo komodu danas.
• or Mi ćemo sastaviti komodu danas.

Using ćemo first without mi can sound less natural in isolation. Since ćemo is a clitic-like auxiliary, it usually prefers not to stand at the very beginning unless something comes before it.

So the most natural options are:

• Sastavićemo komodu danas.
• Mi ćemo sastaviti komodu danas.
• Danas ćemo sastaviti komodu.

Because komodu is in the accusative case, which is used for the direct object.

The noun is:

• komoda = a chest of drawers / dresser

But after the verb, when it is the thing being assembled, it becomes:

• komodu

For feminine nouns ending in -a, the accusative singular usually changes:

• -a → -u

Examples:

• Imam knjigu. = I have a book.
• Kupujem stolicu. = I am buying a chair.
• Sastavićemo komodu. = We will assemble the dresser.

Komoda usually means a dresser, chest of drawers, or sometimes a cabinet-like storage piece, depending on context.

So Sastavićemo komodu danas suggests something like:

• assembling a flat-pack dresser
• putting together a chest of drawers

Serbian has no articles. There is no direct equivalent of a or the in normal usage.

So:

• komoda can mean a dresser or the dresser
• komodu can mean a dresser or the dresser as an object

You understand which one is meant from the context.

So Sastavićemo komodu danas could mean:

• We’ll assemble a dresser today
• We’ll assemble the dresser today

Because Serbian verb endings usually already show the subject.

Here, -ćemo tells you it is we will. So mi is not necessary.

• Sastavićemo komodu danas. = We will assemble the dresser today.
• Mi ćemo sastaviti komodu danas. = also We will assemble the dresser today

You add mi only if you want emphasis, contrast, or clarity.

For example:

• Mi ćemo sastaviti komodu, a oni sto.
  • We will assemble the dresser, and they the table.

Sastaviti is a perfective verb. That means it focuses on the action as a completed whole.

So this sentence suggests:

• we will finish putting it together
• we will assemble it completely

If you wanted to focus more on the process or repeated action, Serbian would often use an imperfective verb instead, such as sastavljati in the appropriate context.

So:

• sastaviti = assemble, put together, complete the assembly
• sastavljati = be assembling / assemble repeatedly / focus on process

Yes, danas can move. Serbian word order is fairly flexible, although some placements sound more natural depending on emphasis.

All of these are possible:

• Sastavićemo komodu danas.
• Danas ćemo sastaviti komodu.
• Komodu ćemo sastaviti danas.

The difference is mainly focus:

• Sastavićemo komodu danas.
  Neutral: we’ll assemble the dresser today.

• Danas ćemo sastaviti komodu.
  Emphasizes today.

• Komodu ćemo sastaviti danas.
  Emphasizes the dresser.

A rough pronunciation guide is:

• sa-sta-VI-će-mo

And the whole sentence roughly:

• sa-sta-VI-će-mo ko-MO-du DA-nas

A few useful sound notes:

• ć is a soft sound, somewhat like a very soft ch or ty sound
• č and ć are different in Serbian
• Serbian spelling is very phonetic, so words are usually pronounced close to how they are written

In sastavićemo, the letter is ć, not č.

Very roughly:

• č is harder, like the ch in church
• ć is softer

This difference matters in Serbian, because they are different sounds and different letters.

So:

• sastavičemo would be incorrect
• sastavićemo is correct

It is neutral. It is not especially formal or especially informal.

You could say it:

• in everyday conversation
• while making plans
• when talking about furniture assembly
• in a practical or household context

It sounds like normal spoken or written Serbian.

No. Serbian mi and the verb form -ćemo do not distinguish between:

• we including you
• we excluding you

So Sastavićemo komodu danas simply means we will assemble the dresser today, and context tells you who we refers to.
