Biramo puno radno vrijeme ili nepuno radno vrijeme.

Biramo is the 1st person plural present tense of birati, meaning to choose.

So it means we choose, we are choosing, or sometimes we’re opting for, depending on context.

A useful extra note:

• birati is the imperfective verb, so it focuses on the process or general act of choosing.
• The perfective partner is izabrati.

In this sentence, biramo is a very natural choice.

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

• biram = I choose
• biraš = you choose
• bira = he/she/it chooses
• biramo = we choose

So biramo already contains the idea of we, and adding mi would usually only be for emphasis:

• Mi biramo... = We are the ones choosing...

Puno radno vrijeme means full-time work or full-time working hours.

Literally:

• puno = full
• radno = working / work-related
• vrijeme = time

So the phrase literally means something like full working time, but in normal English it is best translated as full-time.

Nepuno radno vrijeme means part-time work or part-time hours.

Literally:

• ne- = not / non-
• puno = full
• so nepuno = not full

Yes, this is a normal and standard expression, especially in formal, administrative, and employment-related language.

You may also see related phrases such as:

• raditi na nepuno radno vrijeme = to work part-time
• zaposlen na nepuno radno vrijeme = employed part-time

Because vrijeme is a neuter noun, so the adjective must also be in the neuter singular form.

The adjective is radni in its basic dictionary form, but it changes to match the noun:

• radni dan = working day, workday (dan is masculine)
• radna soba = study / work room (soba is feminine)
• radno vrijeme = working time / working hours (vrijeme is neuter)

So radno is used because it agrees with vrijeme.

Because the words must agree grammatically.

Here, vrijeme is:

• singular
• neuter
• functioning as the direct object of the verb

So the adjectives also appear in the matching neuter singular form:

• puno
• radno
• vrijeme

The same happens in nepuno radno vrijeme.

These phrases are in the accusative case because they are the direct objects of biramo.

We are choosing what?

• puno radno vrijeme
• nepuno radno vrijeme

However, for many neuter singular nouns, the accusative looks exactly the same as the nominative. That is why it looks like the dictionary form.

So even though it is accusative here, it looks unchanged:

• nominative: puno radno vrijeme
• accusative: puno radno vrijeme

Because here puno is an adjective meaning full, not the adverb/noun-like word meaning a lot.

Compare:

• puno radno vrijeme = full-time work
  Here puno agrees with vrijeme and means full.

• Puno radim. = I work a lot.
  Here puno means a lot.

So the meaning depends on how the word is being used in the sentence.

In this sentence, repeating the whole phrase is the clearest and most natural option:

• Biramo puno radno vrijeme ili nepuno radno vrijeme.

Yes, Croatian can sometimes omit repeated words if the meaning is obvious, but in a sentence like this, full repetition sounds more complete and standard.

A shortened version might be possible in conversation, but the full version is better for learners and very natural in formal language.

It can mean either one, depending on context.

Croatian present tense often covers both:

• we choose
• we are choosing

So this sentence could describe:

• a general choice
• a current decision in progress
• a habitual or repeated situation

Context tells you which English translation is best.

No. Croatian does not have articles like a/an or the.

So puno radno vrijeme can mean:

• full-time work
• a full-time position
• the full-time option

The exact English article depends on context, not on a separate Croatian word.

Yes. A Croatian speaker might also say something like:

• Biramo između punog i nepunog radnog vremena.
  = We are choosing between full-time and part-time work.

This version uses:

• između = between
• punog / nepunog / radnog vremena in the genitive case

Your original sentence is still completely correct and natural; this is just another common structure.

Vrijeme is roughly pronounced vrye-meh.

A few pronunciation tips:

• vr comes together at the start, with no vowel in between
• ije here sounds approximately like ye
• stress in Croatian is not usually marked in normal writing, so learners often focus first on getting the sounds right

A rough pronunciation of the whole sentence is:

Bee-rah-moh poo-noh rad-noh vrye-meh ee-lee neh-poo-noh rad-noh vrye-meh

That is only an approximation, but it is a helpful starting point.
