Sve radi savršeno.

Sve here means everything.

Serbian distinguishes between:

• sve = everything / all things
• svi = all (people or masculine plural nouns)

In Sve radi savršeno, sve is treated as everything, so sve is the correct form.

Compare:

• Sve je dobro. = Everything is good.
• Svi su ovde. = Everyone is here / All are here.

Yes, raditi literally means to work, but in Serbian it is also very commonly used for machines, devices, systems, software, plans, and processes in the sense of:

• to work
• to function
• to operate
• to run

So Sve radi savršeno means something like:

• Everything works perfectly
• Everything is working perfectly
• Everything functions perfectly

This is a very natural Serbian sentence.

Because sve is treated grammatically as singular here.

Even though everything refers to many things in meaning, Serbian usually uses neuter singular agreement with sve in this kind of sentence.

So:

• sve radi = correct
• sve rade = not correct here

This is similar to:

• Sve je spremno. = Everything is ready.

Radi is:

• 3rd person singular
• present tense
• from the verb raditi

So the basic pattern is:

• ja radim = I work
• ti radiš = you work
• on/ona/ono radi = he/she/it works

Since sve takes singular agreement here, we use radi.

It can mean both, depending on context.

Sve radi savršeno can be understood as:

• Everything works perfectly
• Everything is working perfectly

Serbian present tense often covers both the English simple present and present continuous, especially with verbs like raditi when talking about how something functions.

Context tells you which English translation fits best.

Savršeno is an adverb here, meaning perfectly.

It describes how everything works:

• radi kako? → savršeno
• works how? → perfectly

Compare:

• savršен / savršena / savršeno can also be an adjective meaning perfect
• but in this sentence, savršeno functions adverbially: perfectly

Examples:

• Auto radi dobro. = The car works well.
• Sve radi savršeno. = Everything works perfectly.

Serbian often leaves out subject pronouns when they are not needed, and in this sentence there is no separate is because the main verb is radi = works / is working.

So the sentence structure is simply:

• Sve = everything
• radi = works / is working
• savršeno = perfectly

Unlike English, Serbian does not need an extra dummy subject like it, and it also does not need is here because radi already carries the meaning of the action.

Yes, Serbian word order is fairly flexible, but Sve radi savršeno is the most neutral and natural order.

Other orders are possible for emphasis, for example:

• Savršeno radi sve. — possible, but marked and unusual in most normal contexts
• Radi sve savršeno. — also possible only in specific emphatic contexts

For a learner, the safest choice is:

• Sve radi savršeno.

Yes. Sve funkcioniše savršeno also means Everything functions perfectly.

The difference is mainly style:

• radi is very common, everyday, and natural
• funkcioniše sounds a bit more formal or technical

Both are correct, but Sve radi savršeno is often the more idiomatic everyday choice.

It is pronounced approximately:

SAVR-she-no

More carefully:

• sa as in supper (short a)
• vr said together
• š like sh in shoe
• e like e in bed (but cleaner/shorter)
• no with a clear o

So:

• savršeno = savr-she-no

Also, the letter š always sounds like English sh.

No. It is very common for machines, devices, software, and systems, but it can also be used more broadly for anything that is functioning smoothly.

For example, it could refer to:

• a computer setup
• a plan
• a process
• a business operation
• a household system

So depending on context, Sve radi savršeno can mean:

• all the equipment works perfectly
• the whole system is running perfectly
• everything is going perfectly on a practical level

Yes, but it depends on the structure.

By itself, sve often means everything:

• Sve znam. = I know everything.

But it can also mean all with another noun:

• sve knjige = all the books
• sve vreme = all the time

In Sve radi savršeno, since there is no noun after it, the meaning is everything.
