Eu quero comprar arroz e feijão para o almoço.

Yes, you can often drop eu in Portuguese.

Portuguese is a pro-drop language, which means the verb ending often already shows the subject:

• eu quero = I want
• você quer = you want
• nós queremos = we want

So Quero comprar arroz e feijão para o almoço is perfectly natural if the subject is clear from context.

You might keep eu when:

• you want emphasis: Eu quero, não ele
• you want clarity
• you are starting a sentence and want it to sound a bit more explicit

Quero is the first-person singular form of the verb querer, which means to want.

Its present tense forms are:

• eu quero = I want
• você/ele/ela quer = you/he/she wants
• nós queremos = we want
• vocês/eles/elas querem = you all/they want

So in this sentence, quero matches eu.

Because after querer, Portuguese usually uses another verb in the infinitive.

So the pattern is:

• querer + infinitive
• eu quero comprar = I want to buy
• eu quero comer = I want to eat
• eu quero sair = I want to leave

This works much like English want to + verb, except Portuguese does not use a separate word equivalent to to here. The infinitive itself does that job.

In Portuguese, food items are often used without articles when speaking generally or when referring to them as things you want to buy, eat, cook, etc.

So:

• comprar arroz e feijão = buy rice and beans

This is very natural.

You may also hear articles in other contexts, for example:

• O arroz está pronto. = The rice is ready.
• O feijão de hoje está ótimo. = Today’s beans are great.

So the absence of articles here does not sound incomplete.

Because Portuguese often treats feijão as a mass noun or a general food category, much like English rice.

So:

• arroz = rice
• feijão = beans / bean dish / beans in general

Even though English often uses the plural beans, Portuguese commonly uses singular feijão when talking about the food in a general sense.

If you specifically mean individual beans, context may change things, but in everyday food talk, feijão in the singular is very normal.

Para o almoço means for lunch or more literally for the lunch meal.

Breakdown:

• para = for
• o = the
• almoço = lunch

So:

• para o almoço = for lunch

In natural English, you would usually just say for lunch, but Portuguese often uses the article here.

Portuguese uses definite articles more often than English.

So where English says:

• for lunch
• after dinner
• before school

Portuguese may say:

• para o almoço
• depois do jantar
• antes da escola

This is very normal and not especially formal. In Portuguese, o almoço sounds natural where English would simply say lunch.

Yes. In spoken Brazilian Portuguese, pra is a very common informal form of para.

So you may hear:

• Eu quero comprar arroz e feijão pra o almoço

However, many speakers would actually prefer the contraction:

• pro almoço = para o almoço

So in everyday speech, these are common:

• para o almoço = standard/full form
• pro almoço = very common spoken contraction

In careful writing, para o almoço is the safest choice.

Yes. Para o commonly becomes pro in Brazilian Portuguese.

So:

• para o almoço → pro almoço

This is extremely common in speech and informal writing.

Similarly:

• para a → pra
• para os → pros
• para as → pras

So a very natural spoken version would be:

• Eu quero comprar arroz e feijão pro almoço.

The original word order is very natural:

• Eu quero comprar arroz e feijão para o almoço.

You can also say:

• Quero comprar arroz e feijão para o almoço.
• Para o almoço, eu quero comprar arroz e feijão.

The first is the most neutral.
The second is also normal because eu can be omitted.
The third puts emphasis on for lunch.

So yes, the order can change, but the original sentence is a standard, natural structure.

A few pronunciation points help a lot here:

• feijão sounds roughly like fay-ZHAWNG
• almoço sounds roughly like al-MO-soo in Brazilian pronunciation, though the final vowel is often lighter

Important details:

• ão is a nasal sound. English does not have an exact equivalent.
• In feijão, the stressed syllable is the last one: -jão
• The ç in almoço sounds like s

So:

• feijão = fei-jão
• almoço = al-mo-ço

They help show pronunciation.

• feijão has ã, which marks a nasal vowel
• almoço has ç, which tells you the c is pronounced like s

So:

• ã = nasal sound
• ç = s sound before o, a, or u

Without these marks, the pronunciation would be different or unclear.

Yes, very much.

Arroz e feijão is one of the most common and culturally familiar food pairings in Brazil. It often refers to a basic everyday meal, not just two random ingredients.

So this sentence sounds especially natural in Brazilian Portuguese because rice and beans is such a normal lunch combination.

Yes, but the meaning changes.

• Eu quero comprar arroz e feijão para o almoço. = I want to buy rice and beans for lunch.
• Eu quero comer arroz e feijão no almoço / no almoço. = I want to eat rice and beans for lunch.

So:

• comprar = to buy
• comer = to eat

The sentence with comprar focuses on getting the food, not eating it.

Both are possible, but they mean slightly different things.

• para o almoço = for lunch, intended for lunch
• no almoço = at lunch / during lunch / for lunch in some contexts

Examples:

• Vou comprar arroz e feijão para o almoço. = I’m going to buy rice and beans for lunch.
• Eu como arroz e feijão no almoço. = I eat rice and beans at lunch.

So in your sentence, para o almoço is the best choice because it shows purpose: you are buying it for that meal.
