Čim krenemo, proverićemo red vožnje.

Čim means as soon as, once, or the moment that. It introduces a time clause.

So Čim krenemo, proverićemo red vožnje means that the second action happens immediately after the first one starts.

This is very common in Serbian. After time words like čim, kad, and posle što / nakon što in certain contexts, Serbian often uses the present tense to talk about a future event.

So krenemo is grammatically present, but here it refers to a future action:

• Čim krenemo... = As soon as we leave/start off...

This is similar to English, which also often avoids will in time clauses:

• As soon as we leave, we’ll check the timetable.
• not normally As soon as we will leave...

Krenemo comes from the verb krenuti, which is usually perfective. It focuses on the action as a single completed event: to set off / to start moving / to leave.

Krećemo comes from kretati (se) or from the present of krenuti depending on usage, but learners usually notice a difference in nuance:

• krenuti / krenemo = to set off, begin, start in a more definite, one-time sense
• kretati / krećemo = to be setting off, to start going, or a more repeated/process-like meaning depending on context

In this sentence, krenemo fits well because it means once we set off.

Here krenemo most naturally means we set off, we leave, or we get going.

The verb krenuti can have a few related meanings depending on context:

• start moving
• leave
• set off
• begin

In this sentence, it probably means something like:

• As soon as we leave
• As soon as we get going

Proverićemo is the future tense of proveriti = to check / verify.

It is made from:

• proveriti = infinitive
• future auxiliary from hteti = ćemo for we will

In Serbian, this can appear in two common ways:

• proverićemo
• ćemo proveriti

Both mean we will check.

The one-word form is very common and natural.

There is no real difference in meaning. Both mean we will check.

• proverićemo is the fused future form
• ćemo proveriti keeps the auxiliary separate

Both are standard. In many sentences, the choice depends on style, rhythm, or word order.

For example:

• Proverićemo red vožnje.
• Ćemo proveriti red vožnje. → this is generally not used at the start of a sentence
• Mi ćemo proveriti red vožnje.
• Čim krenemo, proverićemo red vožnje.

So in your sentence, proverićemo is the most natural form.

Red vožnje is a fixed expression meaning timetable or schedule for transport.

Literally, it is something like:

• red = order, sequence
• vožnje = of driving / of rides / of transport

So the phrase means something like the schedule of departures and arrivals.

The word vožnje is in the genitive because it depends on red:

• red
  • genitive

This combination is just the standard Serbian phrase for a bus, train, or transport timetable.

Because Čim krenemo is a subordinate clause placed before the main clause.

Structure:

• Čim krenemo = subordinate time clause
• proverićemo red vožnje = main clause

When the subordinate clause comes first, Serbian normally separates it with a comma.

So the comma works much like in English:

• As soon as we leave, we’ll check the timetable.

Both main verbs here are perfective:

• krenuti → krenemo
• proveriti → proverićemo

Perfective verbs present actions as whole, bounded events:

• krenemo = once we set off
• proverićemo = we will check it once

This makes sense because the sentence talks about two single future actions happening in sequence.

If imperfective verbs were used, the meaning would usually shift toward process, repetition, or ongoing activity.

Yes. Serbian word order is flexible, though some versions sound more natural than others.

Your sentence:

• Čim krenemo, proverićemo red vožnje.

Possible variation:

• Proverićemo red vožnje čim krenemo.

This means the same thing: We’ll check the timetable as soon as we leave.

The version with čim first puts more focus on the timing: as soon as we set off.

This is a very common learner question.

• č is a harder sound, roughly like ch in chocolate, but usually stronger
• ć is softer, made a bit closer to the middle/front of the mouth

So:

• Čim begins with č
• proverićemo contains ć

Many English speakers do not clearly distinguish these at first, and that is normal. In careful Serbian, the difference matters.

A rough guide:

• č = harder ch
• ć = softer, more palatal ty/ch sound

You do not need a perfect accent immediately, but it is good to notice that Serbian treats them as different sounds.
