Eu recebo o salário todo mês.

In Brazilian Portuguese, the subject pronoun is often optional because the verb ending already shows who the subject is.

• recebo = I receive
• eu recebo = I receive

Adding eu can give emphasis, clarity, or contrast. In everyday speech, both are natural.

• Recebo o salário todo mês.
• Eu recebo o salário todo mês.

Both mean the same thing here.

Recebo is the present tense of the verb receber (to receive).

It is the 1st person singular form:

• eu recebo = I receive

In Portuguese, the present tense can also express a habitual action, so here it means something like:

• I receive my salary every month
• I get paid every month

Because it is the eu form of the verb in the present tense.

The verb receber is an -er verb. Its present tense forms are:

• eu recebo
• você/ele/ela recebe
• nós recebemos
• vocês/eles/elas recebem

So the -o ending is typical for the I form in many Portuguese verbs.

O is the masculine singular definite article, meaning the.

• o salário = the salary

Portuguese uses definite articles more often than English does. In this sentence, o salário sounds natural and specific: it refers to the salary the speaker regularly receives.

Because salário is a masculine noun in Portuguese.

So it takes:

• o in the singular: o salário
• os in the plural: os salários

This grammatical gender is something you usually need to learn together with the noun.

Todo mês means every month.

Here, todo means every when it comes before a singular noun without an article:

• todo mês = every month
• todo dia = every day
• toda semana = every week

So todo mês expresses regular repetition.

Both are correct, but they are structured a little differently:

• todo mês = every month
• todos os meses = every month / all the months

In many everyday situations, they mean basically the same thing.
Todo mês is shorter and very common in speech.

Compare:

• Eu recebo o salário todo mês.
• Eu recebo o salário todos os meses.

Both are natural.

Because it agrees with the singular noun mês.

• todo mês = every month
• toda semana = every week
• todo ano = every year

If the noun were plural, the form would change:

• todos os meses

So todo must match the gender and number of the noun it goes with.

Yes, depending on context, it can sound like to receive/get paid a salary. But literally, receber means to receive.

In this sentence:

• Eu recebo o salário todo mês.

the idea is that the person gets their salary every month. In natural English, you might translate it as:

• I receive my salary every month
• I get paid every month

Yes, but it changes the nuance a bit.

• receber salário focuses on receiving the pay
• ganhar salário can focus more on earning or making a salary

For example:

• Eu recebo o salário todo mês. = I receive my salary every month.
• Eu ganho um bom salário. = I earn a good salary.

So receber is especially natural when talking about the act of being paid.

It could be. Both are possible:

• Eu recebo o salário todo mês.
• Eu recebo meu salário todo mês.

Using meu salário makes the possession more explicit: my salary.

Using o salário is also natural in Portuguese, especially when the context already makes it obvious whose salary it is. Portuguese often uses the definite article where English might prefer a possessive.

The stress falls on lá:

• sa-LÁ-rio

The written accent mark in salário shows the stressed syllable.

So it is pronounced roughly like:

• sa-LAH-ree-o

In Brazilian Portuguese, the final -rio is usually pronounced as part of two syllables: ri-o.

Mês is pronounced with one syllable, and the vowel is stressed.

A rough English approximation is something like mess, but that is not exact.

Important points:

• the ê has a closed vowel sound
• the final s is pronounced like s in Brazilian Portuguese in most accents here
• the accent mark shows stress: mês

Also note the plural:

• mês = month
• meses = months

Yes, but some orders sound more natural than others.

Most natural:

• Eu recebo o salário todo mês.

Also possible:

• Todo mês, eu recebo o salário.

That version puts emphasis on the time expression every month.

Less common in neutral speech:

• Eu todo mês recebo o salário.

This is understandable, but it sounds more marked or stylistic.

Yes, it is natural and correct.

A Brazilian might also say:

• Eu recebo meu salário todo mês.
• Eu sou pago todo mês. (less direct equivalent of I get paid every month)
• Recebo salário todo mês.

But your original sentence is fully natural and grammatically correct.

The infinitive is receber, which means to receive.

So:

• receber = to receive
• eu recebo = I receive

This is the dictionary form you would look up.

Mês is masculine.

So you say:

• o mês = the month
• um mês = a month
• todo mês = every month

Its plural is:

• os meses = the months

Yes. In this sentence, the present tense expresses a habitual action.

So Eu recebo o salário todo mês does not mean that the person is receiving the salary at this exact moment. It means this happens regularly.

This is very common in Portuguese:

• Eu estudo à noite. = I study at night.
• Ela trabalha de manhã. = She works in the morning.
• Eu recebo o salário todo mês. = I receive/get my salary every month.
