Razgovarajmo u četiri oka.

Razgovarajmo is the 1st person plural imperative of razgovarati.

In practical terms, it means let's talk or let's have a conversation.

So this form is used when the speaker includes themself:

• Razgovarajmo. = Let's talk.
• not Talk! to one person
• not We talk as a statement

It is a very common Croatian way to make a suggestion or invitation.

Because razgovarajmo and razgovaramo do different jobs.

• razgovaramo = we are talking / we talk
  This is the present tense.
• razgovarajmo = let's talk
  This is the imperative.

Compare:

• Sada razgovaramo. = We are talking now.
• Razgovarajmo kasnije. = Let's talk later.

So the -jmo ending is a clue that this is a let's... form.

It is an idiom meaning:

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

Literally, it looks like in four eyes, but you should learn it as a fixed expression.

It usually suggests a private conversation, often about something personal, serious, or sensitive.

Because the idiom imagines two people, and each person has two eyes:

• 2 people × 2 eyes = 4 eyes

English does not use this exact image, but Croatian does. So u četiri oka is just the normal Croatian expression for a private, two-person conversation.

This is a very common grammar point with Croatian numbers.

After dva, tri, četiri (2, 3, 4), nouns often appear in a special counted form. With oko (eye), that form is oka:

• jedno oko = one eye
• dva oka = two eyes
• tri oka = three eyes
• četiri oka = four eyes

So četiri oči would sound wrong here.
After the number četiri, the correct form is oka.

Yes, usually it strongly suggests exactly two people: the speaker and one other person.

If more people are present, the phrase normally does not fit. It is specifically about a private conversation between two people.

So this sentence implies:

• you and I should talk privately
• not let's all talk privately as a group

It is quite neutral.

It can work in:

• everyday conversation
• workplace situations
• serious discussions
• polite but direct requests

The phrase itself often sounds a little serious, because asking to speak u četiri oka can suggest:

• something important
• something personal
• something delicate

But grammatically it is not especially formal or informal.

Yes, razgovarati is very natural here because it means to have a conversation / to talk with someone.

You may also hear:

• Popričajmo u četiri oka. = Let's have a little talk in private.
• Moramo razgovarati u četiri oka. = We need to talk in private.
• Htjela bih razgovarati s tobom u četiri oka. = I'd like to speak with you privately.

A verb like pričati is possible in some contexts, but razgovarati sounds especially natural for a serious or mutual conversation.

No, Croatian word order is fairly flexible, but Razgovarajmo u četiri oka is the most natural basic order.

You could change the order for emphasis, for example:

• U četiri oka razgovarajmo.

But that sounds more marked or stylistic.
For normal use, the original order is the safest choice.

It usually sounds:

• direct
• serious
• private
• sometimes slightly tense, depending on context

It does not automatically sound rude, but it can feel weighty because private conversations are often important.

For example, it could be used when someone wants to:

• discuss a problem
• say something confidential
• avoid speaking in front of others

So the sentence is not just about talking — it also suggests privacy and importance.

A simple learner-friendly pronunciation guide is:

raz-go-VA-rai-mo u CHE-ti-ri O-ka

A few tips:

• r is rolled or tapped
• j sounds like English y
• č sounds like ch in chocolate
• u sounds like oo in food

So:

• razgovarajmo ≈ raz-go-VA-rai-mo
• u četiri oka ≈ oo CHE-ti-ri O-ka

Yes, absolutely. It is a normal and idiomatic expression.

It is especially common in sentences like:

• Moramo razgovarati u četiri oka.
• Mogu li razgovarati s tobom u četiri oka?
• Htio bih s vama porazgovarati u četiri oka.

So this is not a textbook-only phrase. It is a real, useful expression worth learning as a whole chunk.
