Todos seguem o regimento interno na área comum.

Here todos means everyone or all people in a general sense.

In Portuguese, todos can work like a pronoun by itself:

• Todos seguem... = Everyone follows...

It can also come before a noun:

• Todos os moradores seguem... = All the residents follow...

So in this sentence, todos stands alone and means everyone.

Because todos is grammatically plural.

The verb seguir must agree with the subject:

• eu sigo
• você/ele/ela segue
• nós seguimos
• eles/elas seguem

Since todos corresponds to they / all of them, Portuguese uses seguem.

So:

• Todos seguem = Everyone follows

Even though English often uses everyone with a singular verb, Portuguese treats todos as plural here.

Seguem is the present indicative of seguir.

In this sentence, it expresses a general fact, rule, or habitual action:

• Todos seguem o regimento interno... = Everyone follows the internal rules / Everyone complies with the house rules.

So it is not necessarily happening only right now at this exact moment. It can describe a normal or expected situation.

Here seguir means something like to follow, to comply with, or to obey a rule.

Portuguese seguir can be used in different ways:

• seguir alguém = to follow someone
• seguir uma tradição = to follow a tradition
• seguir regras = to follow rules

In this sentence, seguir o regimento interno means following the rules or regulations of the place.

Portuguese often uses the definite article more naturally than English does.

So:

• o regimento interno = the internal regulations / the house rules

Even when English might say something more generally like follow house rules, Portuguese commonly says:

• seguir o regimento interno
• seguir as regras
• cumprir o regulamento

The article o is there because regimento is a masculine singular noun.

Regimento interno refers to the internal rules, bylaws, or regulations of an institution, building, condominium, school, club, or similar place.

Depending on context, it could be translated as:

• internal regulations
• house rules
• bylaws
• internal rulebook

In everyday Brazilian Portuguese, people may also say:

• regulamento interno
• as regras do condomínio
• as regras do local

Regimento interno sounds a bit formal or administrative.

Because na is a contraction of em + a.

• em = in / at
• a = the

So:

• em a área comum → na área comum

This contraction is standard in Portuguese.

Other common contractions:

• em + o = no
• de + o = do
• de + a = da

So na área comum means in the common area.

Área comum means common area or shared area.

It is often used for places shared by residents, users, or visitors, such as in:

• apartment buildings
• condominiums
• offices
• clubs

Examples of áreas comuns:

• hallway
• lobby
• elevator area
• shared garden
• pool area

So na área comum means in the common area or in shared spaces.

The word área has a written accent because the stress falls on the first syllable: Á-re-a.

The accent mark shows the correct stress and pronunciation.

Also, área has three syllables in Portuguese:

• á-re-a

This is different from how an English speaker might first guess it.

Yes. Portuguese allows some flexibility.

The original sentence:

• Todos seguem o regimento interno na área comum.

You could also say:

• Na área comum, todos seguem o regimento interno.

That version puts more emphasis on the location.

Both are natural. The original sounds like a neutral statement. The second highlights in the common area a bit more.

Yes, absolutely.

• Todos seguem o regimento interno.
• Todo mundo segue o regimento interno.

Both can mean Everyone follows the rules.

There is a grammar difference:

• todos takes a plural verb: seguem
• todo mundo takes a singular verb: segue

So:

• Todos seguem...
• Todo mundo segue...

In everyday Brazilian Portuguese, todo mundo is extremely common in speech.

No, because comum describes área, not todos.

The phrase is:

• a área comum = the common area

Here:

• área is singular
• comum agrees with área, so it stays singular too

If the noun were plural, then it would change:

• as áreas comuns = the common areas

So the number of todos does not affect área comum.

Grammatically, na área comum is singular and definite, so it usually suggests the common area of a specific place or building.

In real use, though, singular forms like this can sometimes refer more generally to the shared space of the place.

If someone wanted to be more explicitly plural, they could say:

• nas áreas comuns = in the common areas

So:

• na área comum = in the common area
• nas áreas comuns = in the common areas

Which one sounds best depends on context.
