Ako stojiš daleko, preko razglasa nećeš dobro čuti na koji kolosijek trebaš ići.

Croatian often drops subject pronouns when they are not needed, because the verb ending already shows who the subject is.

Here, the endings tell you it is you (singular, informal):

• stojiš = you stand / are standing
• nećeš = you will not
• trebaš = you need / should

You could add ti for emphasis, but normally it is omitted.

Ako means if.

It introduces a conditional clause:

• Ako stojiš daleko... = If you are standing far away...

This is a very common word in Croatian.

Stojiš is the 2nd person singular present tense of stajati or stojati in everyday use, meaning to stand.

So:

• stojim = I stand / am standing
• stojiš = you stand / are standing
• stoji = he/she/it stands

In this sentence, stojiš daleko means you are standing far away.

Because daleko is an adverb, while dalek is an adjective.

Here you need an adverb because it describes how / where someone is standing:

• stojiš daleko = you stand far away

Compare:

• dalek peron = a distant platform → adjective
• stojiš daleko = you are standing far away → adverb

Preko razglasa means over the loudspeaker, through the PA system, or via the station announcement system.

Word by word:

• preko = over / via / through
• razglas = loudspeaker system / public-address system

In this context, it means the information is being announced over speakers at a station.

Because preko normally takes the genitive case.

So:

• razglas = nominative
• razglasa = genitive

That is why you get:

• preko razglasa

This is a useful pattern to remember:

• preko mosta = across the bridge
• preko telefona = over the phone
• preko razglasa = over the loudspeaker

Nećeš čuti is the future tense in Croatian.

It is built with:

• the future form of htjeti (ću, ćeš, će...)
• plus the infinitive

Here:

• ćeš = you will
• nećeš = you will not
• čuti = hear

So:

• čut ćeš / čuti ćeš is not standard here
• nećeš čuti = you will not hear

In negative future, the auxiliary is written as one word:

• neću, nećeš, neće, nećemo, nećete, neće

Because čuti means to hear, while slušati means to listen.

That difference is important:

• čuti = to perceive sound
• slušati = to actively listen

In this sentence, the point is that if you stand too far away, you won’t be able to hear the announcement clearly. So čuti is the natural choice.

Dobro is an adverb meaning well.

So:

• dobro čuti = to hear well
• nećeš dobro čuti = you will not hear well

It describes the quality of hearing, not the content itself.

Na koji kolosijek means to which track.

It uses na because Croatian says ići na kolosijek in the sense of going to / onto a track or platform area.

After a preposition of movement like this, Croatian uses the accusative:

• na koji kolosijek = to which track

A useful comparison:

• na kolosijeku = on the track / at the track → location, so a different case
• na kolosijek = to the track → movement

Also, kolosijek is masculine singular, and for this noun the nominative and accusative look the same, so you see kolosijek in both forms.

Kolosijek means railway track.

At a station, it refers to the track a train will arrive at or leave from. In English, depending on context, this may sometimes be translated more naturally as track rather than literally railway track.

So here it is about understanding which track you need to go to.

Trebaš ići means you need to go or you should go.

• trebati = to need / should
• ići = to go

So:

• trebaš ići = you need to go

A note learners often notice: with trebati + infinitive, Croatian often also uses an impersonal form, especially in more formal or prescriptive grammar. But in everyday speech, the personal form trebaš ići is very common and natural.

Ići is the general verb to go.

Here the sentence is about which track you should go to, so the neutral, general motion verb ići is the most natural choice.

Otići means to leave / go away, and it adds a sense of departure or completion. That is not really the focus here.

So:

• trebaš ići = you need to go
• trebaš otići would sound more like you need to leave/go off

It is an embedded question or indirect question.

It corresponds to the direct question:

• Na koji kolosijek trebaš ići? = Which track do you need to go to?

Inside the larger sentence, it becomes:

• ... nećeš dobro čuti na koji kolosijek trebaš ići.
• ... you won’t hear well which track you need to go to.

Croatian does not do English-style inversion here. English says do you need to go, but Croatian keeps normal verb order:

• trebaš ići

Yes. The forms stojiš, nećeš, and trebaš are all 2nd person singular informal.

So the speaker is addressing one person as ti.

If you wanted the formal or plural version, you would say:

• Ako stojite daleko, preko razglasa nećete dobro čuti na koji kolosijek trebate ići.

Because Ako stojiš daleko is a subordinate if-clause, and when it comes before the main clause, Croatian normally separates it with a comma.

So:

• Ako stojiš daleko, ...

This is similar to English, where a comma is also commonly used after an opening if clause:

• If you stand far away, ...
