Idemo kroz park.

In Serbian, subject pronouns are often omitted because the verb ending already shows who is doing the action.

• idem = I go / am going
• ideš = you go
• ide = he/she/it goes
• idemo = we go / are going
• idete = you plural / formal go
• idu = they go

So idemo already means we go / we are going, and adding mi is usually unnecessary unless you want emphasis:

• Mi idemo kroz park. = We are going through the park.

Idemo is the 1st person plural present tense form of the verb ići (to go).

So:

• ići = to go
• idemo = we go / we are going

This verb is somewhat irregular, so its forms need to be learned rather than built in a completely predictable way.

The preposition kroz requires the accusative case.

The noun park is masculine and inanimate, and for masculine inanimate nouns, the accusative singular is the same as the nominative singular:

• nominative: park
• accusative: park

So:

• kroz park = through the park

By contrast:

• parkom is instrumental
• parka is genitive

Those cases are used in other contexts, but not after kroz.

Kroz means through and expresses movement from one side or part of something to another, or movement within something as a route.

So kroz park suggests passing through the park as part of the journey.

Compare:

• Idemo u park. = We are going to the park.
• Idemo kroz park. = We are going through the park.
• Idemo pored parka. = We are going past / by the park.

Yes, depending on context, Idemo kroz park can sound like either:

• a statement: We’re going through the park
• a suggestion / decision: Let’s go through the park

Serbian often uses the 1st person plural present form this way, especially in conversation.

Context and intonation help make the meaning clear.

For example:

• Neutral description: Idemo kroz park jer je kraće. = We’re going through the park because it’s shorter.
• Suggestion: Idemo kroz park! = Let’s go through the park!

Not completely. Serbian word order is fairly flexible, although Idemo kroz park is the most neutral and natural order.

Other orders are possible for emphasis:

• Kroz park idemo. = Through the park is where we’re going.
• Mi idemo kroz park. = We are going through the park.

Even though the order can change, not every version sounds equally natural in every situation. The basic version is the safest one for learners.

A simple approximate pronunciation is:

EE-deh-moh krohz park

A few details:

• I in Idemo sounds like ee in see
• e sounds like e in met
• r in kroz is rolled or tapped
• z is pronounced like z in zoo

Serbian spelling is quite phonetic, so words are usually pronounced much as they are written.

Ići is generally treated as an imperfective verb of motion. In a sentence like Idemo kroz park, it presents the movement as ongoing, current, or generally happening.

That is why it works naturally for:

• We are going through the park
• We go through the park

Serbian often uses verb aspect very importantly, but here the main thing for a learner is that idemo describes movement in progress or as an uncompleted action.

Serbian has no articles like a or the.

So park can mean:

• a park
• the park

The exact meaning depends on context.

In Idemo kroz park, the listener usually understands which park is meant from the situation.

Yes, several motion-related prepositions are easy to mix up:

• kroz park = through the park
• u park / u parku
  
  • u park = into the park
  • u parku = in the park
• preko parka = across the park
• pored parka = past / next to the park
• do parka = to the park, as far as the park

So if you want the idea of moving through an area, kroz is the right choice.
