Dok igramo, domaćin piše poene.

Here dok means while.

So Dok igramo, domaćin piše poene. means something like While we play, the host keeps score / writes down the points.

A useful thing to know is that dok can also mean until in other contexts, so you have to decide from the sentence which meaning fits. In this sentence, because two actions are happening at the same time, it clearly means while.

Serbian often uses the present tense where English uses either:

• simple present: we play
• or present continuous: we are playing

So:

• igramo = we play / we are playing
• piše = he/she writes / is writing

In this sentence, the present tense shows two actions happening at the same time:

• we are playing
• the host is writing down points

Because Serbian does not have a separate verb form like English am playing, the ordinary present tense does the job.

Igramo is 1st person plural of igrati (to play).

That means:

• igram = I play
• igraš = you play
• igra = he/she plays
• igramo = we play
• igrate = you all / you formal play
• igraju = they play

So dok igramo literally means while we play or more naturally while we’re playing.

Because Serbian often drops subject pronouns when they are already clear from the verb ending.

• igramo already tells you the subject is we
• piše already tells you the subject is he/she/it

Then the noun domaćin is stated explicitly, so there is no need to add a pronoun like on (he).

This is very normal in Serbian. English usually needs the pronoun, but Serbian often does not.

Domaćin usually means host. Depending on context, it can also mean:

• the host of an event
• the host team
• the man of the house / homeowner
• more generally, someone acting as the organizer or host

In this sentence, it most likely means the host of the game or gathering—the person responsible for writing down the score.

Grammatically, domaćin is:

• masculine
• singular
• nominative case
  because it is the subject of piše

A female host would be domaćica.

Yes, piše literally means writes.

But in context, piše poene means writes down the points, so in natural English you would often say:

• keeps score
• writes down the score
• records the points

This is a very normal kind of difference between Serbian and English: the Serbian wording may be more literal, while the most natural English translation is slightly different.

Poene is accusative plural of poen (point).

It is in the accusative because it is the direct object of the verb piše:

• domaćin = subject
• piše = verb
• poene = what he is writing down

For masculine nouns like poen, the plural forms are:

• nominative plural: poeni
• accusative plural: poene

So here poene is exactly what we expect.

Often, yes.

Both poen and bod can refer to a point, but usage depends on context.

• poen is very common in sports and games
• bod is also common for points, especially in scoring systems, rankings, contests, and many sports

So in many situations, piše poene and piše bodove could both make sense. But the most natural choice depends on the specific game or sport.

Because Dok igramo is a subordinate clause placed before the main clause.

The structure is:

• Dok igramo = while we play / while we’re playing
• domaćin piše poene = the host writes down the points

When the dok clause comes first, it is normally separated by a comma.

You can also put the main clause first:

• Domaćin piše poene dok igramo.

That is also natural.

Yes. Serbian word order is fairly flexible.

You can say:

• Dok igramo, domaćin piše poene.
• Domaćin piše poene dok igramo.

Both are correct.

The difference is mainly about focus and style, not basic meaning.

• Starting with Dok igramo emphasizes the time frame: While we’re playing...
• Starting with Domaćin piše poene emphasizes the main action first: The host is writing down points...

Yes, aspect is important here.

Both verbs are imperfective:

• igrati = to play
• pisati = to write

Imperfective verbs are used for:

• ongoing actions
• repeated actions
• background actions
• actions happening over a period of time

That fits this sentence perfectly, because both actions are happening at the same time over some stretch of time:

• we are playing
• the host is writing down points

A perfective verb would usually suggest a completed action, which would not fit as well here.

A rough pronunciation guide:

• domaćin ≈ do-MAH-chin, but the ć is softer than English ch
• poene ≈ po-E-ne

A few details:

• ć is a soft consonant, something between English t and ch, but softer than ordinary č
• oe in poene is pronounced as two vowels, not one long sound:
  • po-e-ne
  • not like a single English vowel sound

So try to say:

• Dok igramo, domaćin piše poene
• with poene clearly in three syllables: po-e-ne

Yes, it is natural and understandable.

It sounds like normal Serbian for While we’re playing, the host keeps score / writes down the points.

Depending on context, a speaker might also say something like:

• Dok igramo, domaćin vodi rezultat.
• Dok igramo, domaćin zapisuje poene.

But your original sentence is perfectly fine and easy to understand.
