Prevoz je dobar.

Prevoz means transport, transportation, or means of transport, depending on context.

In Prevoz je dobar., it most naturally means something like:

• The transportation is good.
• The transport service is good.

It can refer to public transport, a ride, delivery/transport, or transport in a general sense.

Serbian does not have articles like a and the.

So prevoz can mean:

• transport
• the transport
• a transport service

The exact meaning depends on context. In English, you have to choose an article, but in Serbian you usually do not.

Je means is.

It is the 3rd person singular form of the verb biti (to be):

• ja sam = I am
• ti si = you are
• on/ona/ono je = he/she/it is

So:

• Prevoz je dobar. = Transport is good.

Because dobar has to agree with prevoz in gender, number, and case.

Prevoz is a masculine singular noun, so the adjective must also be masculine singular:

• masculine: dobar
• feminine: dobra
• neuter: dobro

So:

• Prevoz je dobar. = correct

If the noun were neuter, then dobro would be used.

One clue is the adjective form: dobar is masculine singular.

Also, many Serbian nouns ending in a consonant are masculine, and prevoz ends in -z.

So:

• prevoz = masculine
• therefore dobar = masculine form of good

The dictionary form is dobar.

It means good, but like many Serbian adjectives, it changes form depending on the noun:

• dobar prevoz = good transport
• dobra knjiga = good book
• dobro mesto = good place

So the form you see depends on what it describes.

This is the most neutral and natural word order.

Serbian word order is more flexible than English, so other orders are possible, for example:

• Dobar je prevoz.
• Je dobar prevoz. — this would usually sound unnatural by itself

But Prevoz je dobar. is the standard way to say it.

Normally, no. In Serbian, the verb to be is usually expressed in sentences like this.

So you should say:

• Prevoz je dobar.

not:

• Prevoz dobar. ❌

Omitting je would sound incomplete in standard Serbian.

A simple English-friendly approximation is:

PREH-vohz

A bit more precisely:

• pre sounds like preh
• voz rhymes roughly with close without the final s sound, but with a voiced z

Stress is usually on the first syllable: PRE-voz.

Sometimes, yes, depending on context.

Prevoz is a broad word. It can refer to:

• transport in general
• transportation service
• a ride/lift
• shipping/transport of goods

So if people are talking about how they got somewhere, Prevoz je dobar. could mean something like The ride is good or The transportation is good. Context decides.

It is in the nominative singular.

Why? Because it is the subject of the sentence:

• Prevoz = subject
• je = is
• dobar = good

In simple X is Y sentences, the subject is normally in the nominative.

Yes, it is grammatical and natural.

It sounds like a general statement such as:

• the transportation is good
• the transport service is good

Depending on the situation, a Serbian speaker might also say something more specific, such as:

• Javni prevoz je dobar. = Public transport is good.
• Prevoz do aerodroma je dobar. = The transport to the airport is good.

But Prevoz je dobar. is perfectly fine on its own.
