O Pedro compra brócolos e peixe no supermercado.

In European Portuguese, it is very common to put the definite article before a person’s name in everyday speech: o Pedro, a Ana, o João.

So O Pedro usually just means Pedro, not a special emphatic the Pedro as it would in English.

A few useful points:

• This is especially common in Portugal.
• In formal writing, the article is sometimes omitted.
• You will hear both forms, but o/a + name is very normal in speech.

Compra is the 3rd person singular present indicative of comprar.

Here it agrees with O Pedro, because Pedro is one person.

So:

• eu compro = I buy
• tu compras = you buy
• ele/ela compra = he/she buys

In this sentence, O Pedro compra... means Pedro buys...

Depending on context, the Portuguese present can also sometimes translate naturally as is buying, but the basic form here is the simple present.

Yes, sometimes the present in Portuguese can be translated in more than one way in English, depending on context.

So O Pedro compra brócolos e peixe can mean:

• Pedro buys broccoli and fish
  or, in the right context,
• Pedro is buying broccoli and fish

However, in European Portuguese, if you specifically want to emphasize an action in progress right now, a very common structure is:

O Pedro está a comprar brócolos e peixe.

That is the typical Portugal Portuguese way to say Pedro is buying broccoli and fish.

In European Portuguese, brócolos is commonly used as a plural noun when talking about broccoli as a food.

That can feel strange to an English speaker, because English usually treats broccoli as an uncountable food word.

So:

• brócolos = broccoli

This is just a vocabulary difference between the languages. Portuguese often talks about this vegetable in the plural form.

A useful Portugal-specific note:

• In Portugal, brócolos is the usual form.
• In Brazil, brócolis is very common instead.

Portuguese often leaves out the article when talking about food or things being bought in a general, non-specific way.

So compra brócolos e peixe means he buys:

• some broccoli
• some fish

It does not have to mean a specific previously mentioned broccoli or fish.

Compare:

• compra brócolos e peixe = buys broccoli and fish / some broccoli and some fish
• compra os brócolos e o peixe = buys the broccoli and the fish

The version in your sentence sounds natural for a general shopping statement.

Because peixe in Portuguese can refer to:

• fish as food
• a fish as an animal
• fish in a general category, depending on context

In this sentence, peixe most naturally means fish as food.

So peixe here is like:

• fish
• some fish

It does not necessarily mean exactly one whole fish.

If you wanted to make it clearly singular and countable, you could say:

• um peixe = one fish

If you wanted a specific fish already known in the conversation:

• o peixe = the fish

No is a contraction of:

em + o = no

So:

• em = in / at / on
• o supermercado = the supermarket
• no supermercado = in the supermarket / at the supermarket

This kind of contraction is very common in Portuguese.

Other examples:

• na = em + a
• nos = em + os
• nas = em + as

Because here supermercado is the place where the buying happens, not the destination of movement.

So:

• comprar no supermercado = to buy at/in the supermarket
• ir ao supermercado = to go to the supermarket

That is the key difference:

• no supermercado = location
• ao supermercado = destination

So this sentence says Pedro buys broccoli and fish at the supermarket, not that he goes there.

Yes. Portuguese often drops the subject when it is clear from context, because the verb ending already gives information about the subject.

So you could hear:

Compra brócolos e peixe no supermercado.

That can mean:

• He buys broccoli and fish at the supermarket
• Pedro buys broccoli and fish at the supermarket, if the context already makes it clear you are talking about Pedro

Still, keeping O Pedro is completely normal, especially when introducing the subject or making it explicit.

No. This is a very normal Portuguese word order:

Subject + verb + object + place

So:

• O Pedro = subject
• compra = verb
• brócolos e peixe = object
• no supermercado = place

This is one of the most basic and common sentence patterns in Portuguese.

English uses the same basic order here, which makes the structure easy to recognize.

The accent mark shows the stressed syllable:

brócolos → stress on bró

So it is pronounced roughly like:

• BRO-co-los

The accent is there because the stress does not follow the most basic default pattern for a word of that shape, so Portuguese marks it.

Very roughly, you can think of the main stresses in the sentence like this:

• PE-dro
• com-pra
• BRÓ-co-los
• pei-xe
• su-per-mer-CA-do

The accent mark in Portuguese is often very helpful because it tells you where the stress goes.
