Daj nam priliku: ostanimo prijatelji i razgovarajmo u četiri oka.

Daj is the 2nd person singular imperative of dati (to give). It means give! when speaking to one person informally.

So:

• Daj nam priliku = Give us a chance (informal, one person)
• Dajte nam priliku = Give us a chance (formal or plural)

In this sentence, daj makes the tone sound direct and personal.

Nam means to us. It is the dative form of mi (we/us).

With dati, Croatian normally uses this pattern:

dati nekome nešto = to give someone something

So here:

• nam = to us
• priliku = a chance

Also, nam is an unstressed pronoun, a clitic, so it usually goes near the beginning of the clause, often in second position. That is why Daj nam priliku sounds natural.

Because priliku is the accusative singular of prilika.

• prilika = nominative singular
• priliku = accusative singular

Here it is the direct object of daj, so Croatian uses the accusative:

Daj nam priliku = Give us a chance

Croatian uses the 1st person plural imperative to express let’s ...

So:

• ostanimo = let’s stay / let’s remain
• razgovarajmo = let’s talk

This is a very common pattern:

• ostani = stay! (singular informal)
• ostanite = stay! (plural/formal)
• ostanimo = let’s stay

And similarly:

• razgovaraj = talk!
• razgovarajte = talk!
• razgovarajmo = let’s talk

Because prijatelji is not the object here. It is a predicate noun after ostati (to remain).

In Croatian, after verbs like biti (to be) and ostati (to remain), the noun is usually in the nominative:

• Mi smo prijatelji = We are friends
• Ostanimo prijatelji = Let’s remain friends

So prijatelji is correct.

Yes. Prijatelji is the masculine plural form, and it is also the usual form for a mixed group or when gender is not being specified.

If both people were female, you would normally say:

Ostanimo prijateljice.

So the sentence as written most naturally suggests either:

• at least one male, or
• a generic/mixed use

Because Croatian often leaves out subject pronouns when the verb ending already shows who the subject is.

Here:

• ostanimo already means let us stay
• razgovarajmo already means let us talk

So adding mi is usually unnecessary. You could add it for emphasis, but the normal sentence does not need it.

It is a very common idiom meaning:

• in private
• one on one
• face to face
• with no one else present

Literally, it means in four eyes, but you should learn it as a fixed expression, not translate it word for word.

So razgovarajmo u četiri oka means something like let’s talk privately or let’s talk one on one.

Because after the numbers dva, tri, četiri, Croatian uses a special counting form of the noun.

The normal plural of oko is oči:

• Moje oči = my eyes

But after četiri, you get:

• četiri oka = four eyes

So in u četiri oka, oka is exactly what you expect after četiri.

Yes, absolutely. That is also natural Croatian.

The difference is mainly style:

• Daj nam priliku: ostanimo prijatelji i razgovarajmo u četiri oka.
  More dramatic, punchy, and rhetorical.

• Daj nam priliku da ostanemo prijatelji i razgovaramo u četiri oka.
  More straightforward grammatically: Give us a chance to remain friends and talk privately.

Both work.

This is about aspect, which is very important in Croatian.

• dati is perfective → daj
  It focuses on one complete act: give us that chance.

• ostati is also perfective → ostanimo
  It focuses on reaching or keeping the resulting state: let’s remain friends.

• razgovarati is imperfective → razgovarajmo
  It focuses on the activity itself: let’s talk.

So the sentence mixes aspects in a natural way:

• a complete act: give
• a resulting state: remain
• an ongoing action: talk
