Reportei o apagão à empresa.

Reportei is the 1st person singular form of the verb reportar in the pretérito perfeito simples.

So it means:

• I reported
• I filed / notified / informed (depending on context)

In this sentence, the speaker is talking about one completed action in the past.

Breakdown:

• reportar = to report
• reportei = I reported

This is a regular -ar verb in this tense:

• eu reportei
• tu reportaste
• ele/ela/você reportou
• nós reportámos (European Portuguese spelling/pronunciation)
• vós reportastes
• eles/elas/vocês reportaram

In Portuguese, the subject pronoun is often left out when the verb ending already makes the subject clear.

So:

• Reportei o apagão à empresa.
• Eu reportei o apagão à empresa.

Both are correct, but the first is more natural in many contexts.

Because reportei clearly means I reported, Portuguese does not need eu unless you want emphasis, contrast, or clarity.

For example:

• Eu reportei o apagão, não foi o João.
  I reported the blackout, not João.

Portuguese often uses the definite article where English may or may not use the.

Here, o apagão means the blackout / the outage and refers to a specific incident.

• o = the
• apagão = blackout / major power outage

Using the article makes the noun sound more complete and natural in this sentence.

Without the article, reportei apagão would sound wrong here.

À is the contraction of:

• a = to
• a empresa = the company

So:

• a + a empresa = à empresa

That accent is called a grave accent and marks crasis: the merging of two a sounds into one written form.

So:

• Reportei o apagão à empresa. = I reported the blackout to the company.

Compare:

• a empresa = the company
• à empresa = to the company

This is one of the most common things learners need to notice in Portuguese writing.

With reportar, the most direct structure is usually:

• reportar alguma coisa a alguém
  to report something to someone

So:

• Reportei o apagão à empresa.

Using para a empresa is not the normal choice here.

In general:

• a alguém is common after verbs of saying, giving, reporting, telling, showing, etc.
• para often suggests direction, destination, or purpose rather than the indirect object pattern used by this verb

So for this sentence, à empresa is the expected structure.

Apagão usually refers to a blackout, especially a large or significant power outage.

It comes from apagar (to switch off / to go out) plus the ending -ão, which can give a stronger or larger sense.

Depending on context, it can suggest:

• a blackout
• a major outage
• a widespread loss of power

In everyday use, apagão often sounds stronger than a small local electrical problem.

If you wanted something more specific, you might also see:

• falha de energia = power failure
• corte de eletricidade = power cut
• avaria elétrica = electrical fault

It is understood and can be used, especially in:

• technical contexts
• customer support
• formal/administrative language
• IT or service issues

However, in European Portuguese, depending on the situation, speakers may also prefer verbs such as:

• comunicar = to communicate / notify
• informar = to inform
• participar = to report formally
• assinalar / sinalizar = to point out / flag
• dar conta de = to report / inform of

For example:

• Comuniquei o apagão à empresa.
• Informei a empresa do apagão.
• Participei o apagão à empresa. (more formal, and less common for many learners)

So reportei is possible, but it may sound a bit more formal, technical, or influenced by international/business usage than some alternatives.

Yes, but the original order is the most neutral:

• Reportei o apagão à empresa.

Other orders are possible for emphasis or style, for example:

• À empresa, reportei o apagão.
  This is more marked and sounds like you are emphasizing to the company.

• O apagão, reportei-o à empresa.
  This is more literary or emphatic, not the most normal everyday phrasing.

In ordinary speech and writing, the basic order:

• verb + direct object + indirect object is the safest and most natural choice here.

Good question, because pronouns in European Portuguese can be tricky.

Replacing o apagão

Since apagão is masculine singular, you use o:

• Reportei-o à empresa.
  = I reported it to the company.

Notice that in European Portuguese, object pronouns are often attached to the verb with a hyphen in affirmative main clauses:

• reportei-o

Replacing à empresa

For to the company, you use the indirect object pronoun lhe:

• Reportei-lhe o apagão.
  = I reported the blackout to it/to them.

Replacing both

You can also combine them:

• Reportei-lho.

That means:

• I reported it to the company / to them

This combined form is correct but may feel quite formal or dense for learners. Many speakers prefer repeating part of the sentence instead of using such a compact pronoun combination.

Because the two nouns play different roles in the sentence.

• o apagão is the direct object: the thing being reported
• à empresa is the indirect object: the recipient of the report

Portuguese often marks the indirect object with a:

• reportar algo a alguém

So the structure is:

• Reportei = verb
• o apagão = what I reported
• à empresa = to whom I reported it

This is similar to English:

• I reported the blackout to the company

A broad European Portuguese pronunciation would sound roughly like:

• Reportei u apagão à empresa

A few useful notes:

• o before a consonant often sounds close to u
• à is a stressed a sound
• empresa in European Portuguese often has a reduced unstressed vowel at the start, something like em-pré-zə
• reportei ends with a sound like -tay

A rough learner-friendly approximation:

• reh-por-TAY u ah-puh-GOWN ah em-PREH-zuh

But the real European Portuguese pronunciation has more vowel reduction than this English-friendly version suggests.

Yes. Even if the basic meaning is already clear, reportei can have slightly different shades depending on context.

It could mean:

• I reported the outage to the company
• I notified the company about the outage
• I filed a report with the company about the outage
• I flagged the outage to the company

So the exact English wording depends on whether the context is:

• customer service
• IT support
• utilities
• a formal complaint
• an internal company process

The Portuguese sentence itself stays the same, but the best English equivalent can shift a little.
