Avverte tutti del problema.

Avverte is the third-person singular present indicative of avvertire.

So it can mean:

• he warns / informs
• she warns / informs
• it warns / informs
• sometimes formal you warn / inform if the subject is Lei

In this sentence, the exact subject is not stated, so context tells you who is doing the action.

Italian often leaves out subject pronouns because the verb ending already shows the person and number.

So instead of saying Lui avverte tutti del problema, Italian commonly just says Avverte tutti del problema.

This is very normal in Italian and is one of the first things English speakers notice, since English usually requires a subject.

Here avvertire means something like to warn, to notify, or to inform.

That matters because avvertire can have other meanings too, such as to feel or to sense in other contexts.

For example:

• Avverte tutti del problema = he/she warns or informs everyone about the problem
• Avverte un dolore = he/she feels a pain

So the structure of the sentence helps you understand which meaning is intended.

Here tutti means everyone or all of them, depending on context.

It is the masculine plural form. In Italian, the masculine plural is also used for:

• a mixed group
• an unspecified group

So tutti does not necessarily mean only men.

Because tutti is plural, while tutto is singular.

Compare:

• tutto = everything / the whole thing
• tutti = everyone / all of them

In this sentence, the speaker is talking about multiple people being warned, so tutti is the right form.

Because with this meaning, Italian often uses the pattern:

avvertire qualcuno di qualcosa

That means to warn / inform someone about something.

So:

• tutti = the people being warned
• del problema = about the problem

If you said Avverte tutti il problema, that would not sound correct in standard Italian for this meaning.

Del is a contraction of di + il.

So:

• di + il = del

In this sentence, del problema literally corresponds to of/about the problem, though in natural English you would usually say about the problem.

This kind of contraction is very common in Italian:

• di + il = del
• di + lo = dello
• di + la = della
• di + i = dei
• di + gli = degli
• di + le = delle

Yes. In Avverte tutti del problema:

• avverte = the verb
• tutti = the direct object
• del problema = a prepositional complement, linked with di

So the structure is basically:

[subject] + avverte + someone + di/about something

That is why tutti comes directly after the verb.

Yes, if the sentence is using the formal Lei form.

In Italian, formal you uses the same verb form as he/she:

• Lei avverte tutti del problema = You inform everyone about the problem

So without context, avverte could refer to:

• he
• she
• formal you

Yes. Tutte would be used if the group is entirely feminine.

So:

• Avverte tutti del problema = everyone / all of them, masculine or mixed group
• Avverte tutte del problema = all of them, feminine group only

English does not usually show this distinction, but Italian does.

They are very close, and in many contexts both can work.

For example:

• Avverte tutti del problema
• Avvisa tutti del problema

Both can mean he/she warns or informs everyone about the problem.

However, avvisare is often the more straightforward everyday verb for to notify / let someone know, while avvertire can sometimes sound a bit broader or slightly more formal depending on context. Still, in many real situations they overlap a lot.

Yes, but Avverte tutti del problema is a normal, neutral order.

Italian word order is somewhat flexible, especially for emphasis. For example, you might also hear:

• Tutti li avverte del problema in a more marked or emphatic structure
• Avverte del problema tutti is much less neutral and usually not the basic choice

For learners, the safest pattern is the standard one: verb + person + di/about thing

Usually from context.

In practice, tutti can cover both ideas:

• everyone
• all of them

If the sentence appears by itself, English might translate it either way depending on what came before. Italian does not need to make the distinction as clearly here as English sometimes does.
