Ako ideš pravo, vidiš most.

Ako means if. It introduces a condition:

• Ako ideš pravo = If you go straight
• vidiš most = you see the bridge / a bridge

So the whole sentence is a normal if-clause + result structure.

Serbian often drops subject pronouns when they are clear from the verb form.

• ideš already means you go (singular, informal)
• vidiš already means you see (singular, informal)

So ti is not necessary. You could say Ako ti ideš pravo, vidiš most, but that sounds more emphatic, like if you go straight...

Ideš is the 2nd person singular present tense of ići = to go.

A few present forms of ići are:

• idem = I go
• ideš = you go
• ide = he/she/it goes
• idemo = we go
• idete = you go
• idu = they go

So here ideš shows the speaker is talking to one person informally.

Here pravo is an adverb, meaning straight or straight ahead.

So:

• ići pravo = to go straight
• idi pravo! = go straight!

In this sentence, pravo describes how you go.

Vidiš is the normal present-tense form meaning you see.

In this kind of sentence, Serbian often uses the present tense for:

• general truths
• directions
• predictable results

So Ako ideš pravo, vidiš most is very natural in the sense of:

• If you go straight, you see the bridge
• more naturally in English: If you go straight, you’ll see the bridge

It is the object here, and it is in the accusative case. The reason it looks unchanged is that for many masculine inanimate nouns, the accusative singular is the same as the nominative singular.

• nominative: most = bridge
• accusative: most = bridge

So vidiš most is correct.

Compare that with a masculine animate noun, where accusative would change:

• vidiš čoveka = you see a man

It can mean a bridge or the bridge, depending on context.

Serbian has no articles, so there is no direct equivalent of a/an/the. Context tells you which meaning is intended.

So vidiš most could mean:

• you see a bridge
• you see the bridge

If the meaning has already been established in context, the listener usually knows which one is meant.

Because the sentence begins with a subordinate ako-clause.

• Ako ideš pravo = dependent clause
• vidiš most = main clause

In standard Serbian writing, when the if-clause comes first, a comma is used before the main clause.

Grammatically, both verbs are in the present tense, but the meaning can feel like a future result in English.

That is very common in Serbian, especially in:

• directions
• instructions
• general cause-and-effect statements

So the Serbian present can correspond to English:

• If you go straight, you see the bridge
• or more naturally: If you go straight, you’ll see the bridge

It is addressed to one person informally.

That is shown by:

• ideš
• vidiš

Both are 2nd person singular forms.

If you were speaking to:

• more than one person, or
• one person formally

you would usually say:

Ako idete pravo, vidite most.

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

The given sentence is very natural:

• Ako ideš pravo, vidiš most.

You could also say:

• Vidiš most ako ideš pravo.

That puts a bit more focus on most / the result.

But the original order is the most straightforward for giving directions.

It is grammatically a condition, but in practice it often works like a direction or route description.

So it can mean something like:

• If you go straight, you’ll see the bridge
• Go straight and you’ll see the bridge

Serbian often uses conditional sentences this way when explaining where something is.

In many situations, yes. Pravo and ravno can both be used for straight in directions.

However, pravo is extremely common in route instructions:

• idi pravo = go straight

Depending on region and style, one may sound more natural than the other, but pravo is completely standard here.

A simple approximate pronunciation for an English speaker is:

AH-koh EE-desh PRAH-voh, VEE-dish most

A few helpful notes:

• š sounds like sh in ship
• č / ć are different sounds in Serbian, but there are none here
• r in pravo is rolled or tapped
• Serbian spelling is very phonetic, so words are usually pronounced as written

Yes. You can say:

Ako ti ideš pravo, vidiš most.

But this is not neutral. It adds emphasis to you, as if contrasting with someone else:

• If you go straight, you see the bridge

In ordinary speech, the version without ti is more natural.

Yes:

Ako ideš pravo, videćeš most.

That means more explicitly:

• If you go straight, you will see the bridge

This version sounds a bit more clearly future-oriented.
The original vidiš most is still very natural, especially in directions and general route descriptions.
