Važne odluke donosimo zajedno.

Because važne odluke is plural and the adjective has to agree with the noun.

• odluka = decision
• odluke = decisions
• važan / važna / važno = important, changing form to match gender, number, and case

Here, odluke is a feminine plural form, so the adjective also becomes važne.

So:

• važna odluka = an important decision
• važne odluke = important decisions

Here, odluke is in the accusative plural, because it is the direct object of donosimo.

The verb donositi in this expression means to make or to bring about a decision, and the thing being made is the object:

• donosimo odluke = we make decisions

A useful thing to notice is that for many feminine nouns ending in -a, the nominative plural and accusative plural look the same:

• nominative plural: odluke
• accusative plural: odluke

So you tell the case from the sentence function, not just the form.

That is a very common question. Literally, donositi often does mean to bring, but in Croatian there is a fixed expression:

• donositi odluke = to make decisions

So this is just like an idiomatic verb-noun combination in English. English says make a decision, while Croatian says bring a decision in a literal sense, but the real meaning is simply make a decision.

This kind of thing is very common across languages, so it is best to learn donositi odluke as a whole phrase.

Donosimo is the 1st person plural present tense form of donositi.

So it means:

• we bring
• or, in this context, we make

The ending -mo tells you it means we.

That is why Croatian does not need the pronoun mi here. The verb already shows the subject.

Because Croatian often leaves subject pronouns out when they are not needed.

In English, you must say we make.
In Croatian, the verb form already tells you who is doing the action:

• donosim = I make / bring
• donosiš = you make / bring
• donosimo = we make / bring

So mi is unnecessary unless you want emphasis:

• Važne odluke donosimo zajedno. = neutral
• Mi donosimo važne odluke zajedno. = we make important decisions, maybe contrasting with someone else

Zajedno means together.

It is an adverb, so it describes how the action is done:

• donosimo zajedno = we make them together

It does not change form here. It stays zajedno.

Croatian word order is more flexible than English word order.

Važne odluke donosimo zajedno is a natural, neutral sentence. But other orders are possible, depending on emphasis:

• Važne odluke donosimo zajedno. = neutral; focus may fall naturally on the whole statement
• Zajedno donosimo važne odluke. = emphasizes together
• Donosimo važne odluke zajedno. = also possible, a bit closer to English order
• Važne odluke zajedno donosimo. = possible, with a slightly marked emphasis

So the sentence can change, but the choice of order affects style and emphasis.

Yes, it matters.

Donositi is imperfective. Its perfective partner is usually donijeti.

In this sentence, the imperfective form is natural because it expresses a general fact, habit, or ongoing practice:

• Važne odluke donosimo zajedno. = We make important decisions together / We make important decisions jointly

If you used the perfective verb, it would usually refer to a completed act of making a particular decision, not a general principle.

So here donosimo suggests a regular way of acting, not one single finished event.

Because Croatian has no articles.

English says:

• an important decision
• the important decisions
• important decisions

Croatian does not use separate words for a/an/the, so the meaning depends on context:

• važna odluka
• važne odluke

In this sentence, važne odluke could mean important decisions or, depending on context, the important decisions.

Yes, depending on context.

The Croatian present tense often covers both:

• a general present: We make important decisions together
• a current ongoing sense: We are making important decisions together

Without extra context, the most natural reading is usually the general one: this is how we make important decisions.

If the speaker wanted to make the ongoing situation especially clear, context would usually do that.

You can tell by matching:

• gender: odluka is feminine
• number: here it is plural
• case: here it is accusative plural

The adjective must match the noun, so:

• singular feminine: važna odluka
• plural feminine: važne odluke

This agreement is one of the most important patterns in Croatian grammar.

Usually, yes. Most Croatian nouns ending in -a are feminine.

So:

• odluka = feminine singular noun
• plural: odluke

That is why the adjective takes the feminine form too.

There are some exceptions in Croatian, but for a beginner, treating most -a nouns as feminine is a very good rule.

A simple learner-friendly approximation is:

VAZH-neh OD-loo-keh do-NO-see-moh za-YED-noh

A few helpful sounds:

• ž sounds like the s in measure
• j sounds like English y
• dj / đ is not in this sentence, but learners often confuse it with j
• Croatian vowels are usually clear and short, not reduced like in English

You do not need perfect pitch accent to say this understandably. Clear consonants and vowels matter more for most learners.
