O Pedro não ignora o perigo quando atravessa a rua principal.

In European Portuguese, it’s very common to use the definite article before a person’s first name:

• O Pedro = Pedro (male)
• A Maria = Maria (female)

This doesn’t translate directly to English; it doesn’t mean “the Pedro”. It’s just a normal, neutral way to refer to someone.

You’ll hear both with and without the article, but in many regions and registers of European Portuguese, using o / a with names is the default in speech. In more formal writing you might see it less.

Yes, you can say:

• Pedro não ignora o perigo quando atravessa a rua principal.

The basic meaning is the same. The difference is mostly stylistic and regional:

• With article (O Pedro): very common in everyday European Portuguese; sounds natural, colloquial, and neutral.
• Without article (Pedro): a bit more formal or “written”, or used in certain dialects/regions that prefer it.

For learning purposes, it’s good to get used to hearing and using O / A + name in European Portuguese.

In Portuguese, não normally comes immediately before the conjugated verb:

• O Pedro não ignora o perigo. – Pedro does not ignore the danger.
• Eu não sei. – I don’t know.

You do not put não after the main verb the way you might in some other languages:

• ❌ O Pedro ignora não o perigo. (wrong)
• ✅ O Pedro não ignora o perigo.

If there is a compound verb (e.g. an auxiliary + main verb), não comes before the first (conjugated) verb:

• O Pedro não vai atravessar a rua. – Pedro is not going to cross the street.

Ignorar has two main meanings in Portuguese:

1. Not know, be unaware of

   • Eu ignoro o motivo. – I don’t know the reason.

2. Deliberately ignore, pay no attention to

   • Ele ignora os conselhos. – He ignores the advice.

In your sentence, não ignora o perigo means:

• He is aware of the danger and does not choose to ignore it.

So it mixes both ideas: he knows the danger exists and he doesn’t pretend it doesn’t.

Portuguese uses definite articles much more than English. Here:

• o perigo literally = the danger.

In English, we sometimes drop the and just say danger, but in Portuguese the article is very common in this type of sentence:

• Ignora o perigo. – He ignores (the) danger.
• Tem medo do escuro. – He is afraid of the dark.

You could say ignora perigo in some stylised, headline-like, or poetic contexts, but in normal speech and writing o perigo is the natural choice.

Portuguese often drops subject pronouns (eu, tu, ele, etc.) because the verb ending already shows who the subject is.

• (Ele) atravessa → the ending -a in atravessa already tells you it’s ele / ela / você / o Pedro.

So both are grammatically correct:

• O Pedro não ignora o perigo quando atravessa a rua principal.
• O Pedro não ignora o perigo quando ele atravessa a rua principal.

The version without ele is more natural and less repetitive, because O Pedro is already the subject of the sentence.

Portuguese uses the simple present much more often than English to talk about:

• habits or repeated actions
• general truths
• typical behaviour

Here, quando atravessa a rua principal means:

• whenever / when(ever) he crosses the main street (habitual)

You could say quando está a atravessar a rua principal, but:

• quando atravessa = more neutral, general, simple
• quando está a atravessar = focuses more on the ongoing process at that moment

For a general, repeated situation, the simple present atravessa is the most natural.

Yes, you can say:

• O Pedro não ignora o perigo quando está a atravessar a rua principal.

Differences:

• quando atravessa

  • more general/habitual: when he crosses the main street (as a rule)
  • shorter, very natural in Portuguese for routine situations.

• quando está a atravessar

  • continuous aspect: when he is in the middle of crossing the main street
  • emphasises the ongoing action at that moment.

Both are correct; in most contexts, natives would pick the shorter quando atravessa.

The verb atravessar already has the idea of “cross (from one side to the other)” built in, and it normally takes a direct object with no extra preposition:

• atravessar a rua – to cross the street
• atravessar o rio – to cross the river
• atravessar a estrada – to cross the road

So:

• atravessa a rua principal = he crosses the main street.

If you wanted “walk along / through the main street”, you’d use a different verb or add a preposition, e.g.:

• andar pela rua principal – to walk along the main street
• passar pela rua principal – to go through / via the main street

In Portuguese, each noun has grammatical gender:

• perigo is masculine → o perigo
• rua is feminine → a rua

There is no logical reason here; it’s just part of each word’s dictionary form, like in many other Romance languages.

Some weak patterns (with many exceptions):

• many nouns ending in -o are masculine: o carro, o livro, o perigo
• many nouns ending in -a are feminine: a rua, a casa, a janela

But you must learn the gender with the noun. A good habit is to always learn new words together with o / a, for example:

• o perigo – danger
• a rua – street

The normal word order in Portuguese is:

• noun + adjective
  
  • a rua principal – the main street
  • o carro vermelho – the red car

So a rua principal is the standard, neutral way to say the main street.

You can sometimes put principal before the noun (a principal rua), but:

• it’s much less common,
• it sounds more formal, literary, or stylistically marked,
• it can subtly change focus or feel slightly unusual in everyday speech.

In everyday European Portuguese, you should say a rua principal.

In this context, principal means main / most important:

• a rua principal – the main street
• a razão principal – the main reason

Other common uses:

• o papel principal – the main role (in a film/play)
• a ideia principal – the main idea

It can also be a noun meaning “principal / headteacher” in school contexts:

• o principal da escola – the school principal (though diretor / diretora is more common in Portugal).

In your sentence, it clearly means the main street.

Key points:

• não

  • ão is a nasal sound roughly like “own” in English said through the nose, but shorter and tenser.
  • The m or n that nasalises the vowel is usually not fully pronounced as a consonant; it just makes the vowel nasal.

• ignora

  • Stressed on -no-: i-gNO-ra
  • The gn is pronounced like “ny” in canyon (similar to Italian gn or Spanish ñ), especially in slower or careful speech: /iˈɲɔɾɐ/ in many accents.
  • In fast speech some speakers make it closer to a palatal /ɲ/ or even simplify it, but aiming for “i-nyo-ra” is a good learner target.

• o perigo

  • o before consonant is usually like English “oo” in food, but shorter.
  • perigo has the stress on -ri-: pe-RI-go.

Putting it together (simplified guide):

• O Pedro não ignora o perigo ≈ oo PE-dru now ee-NYO-ra oo pe-REE-go (with now nasalised).
